Description

Luminaire with protective cover

The invention relates to a system for realizing a lamp that is elongated in the longitudinal direction, a lamp and a method for producing the lamp by means of a system and components of the system according to the invention.

Generic systems are suitable for realizing a lamp that is elongated in a longitudinal direction and has a mounting rail that is elongated in the longitudinal direction and a current-conducting rail that is elongated in the longitudinal direction. The current conducting rail has channels running in the longitudinal direction, which are arranged next to one another in a transverse direction perpendicular to the longitudinal direction. Since the channels are lined up next to each other along the transverse direction, the transverse direction is also sometimes referred to as the line-up direction. At least one conductor wire is arranged in each case in at least some of the channels. The channels are designed to insulate the conductor wires running in them from one another. Correspondingly, the conducting wires also run elongated in the longitudinal direction. Channel walls, which form the channels, run in the transverse direction to insulate the line wires from one another. The channels are preferably open on an access side, with the access side pointing perpendicularly to the transverse direction and perpendicularly to the longitudinal direction, so that the conductors arranged in the channels are accessible from the access side and can therefore be contacted, with the channels preferably being on the access side over their longitudinal extent are continuously open. The channels are preferably on their side facing away from the access side, with which the current conduction rail is preferred on the Mounted adjacent to the mounting rail, closed to isolate the line wires from the mounting rail. Due to their arrangement in the current conducting rail, the conducting wires are arranged at a sufficient distance from the remaining conducting wires in order to be insulated from them. For this purpose, the line wires are preferably arranged such that two adjacent line wires in the transverse direction are either arranged sufficiently spaced apart on different channel walls of a channel or are separated from one another by a channel wall running between them, which separates two channels from one another. Typically, the mounting rail is used to fix the lamp to a structure, such as a ceiling. The current conducting rail with the line wires arranged in its channels is used to supply power to electrical functional elements of the lamp, which are to be fixed at various longitudinal positions along the mounting rail to create a lamp and are electrically conductively connected to at least some of the line wires for the electrical supply. Generic systems often include corresponding functional elements, such as lighting modules, in particular including printed circuit boards with LEDs, control gear, radio modules, sensors such as cameras or other presence detection sensors, etc. Generic systems often also include at least one assembly body, in particular several identically designed assembly bodies. In order to implement a lamp using a system of this type, at least one functional element and a contact device are usually mounted on the mounting body, and the mounting body is appropriately equipped to implement a lamp and is connected to the mounting rail, and the contact device is electrically conductively connected to at least some, in particular all, of the line wires , which are arranged in the current conduction rail brought.

The support rail usually has a support rail base and two extending away from the support rail base in a vertical direction that is perpendicular to the longitudinal direction mounting rail side walls. The carrier rail base runs in the transverse direction between the carrier rail side walls, so that the carrier rail side walls are spaced apart from one another in the transverse direction by the carrier rail base. The transverse direction is perpendicular to the vertical direction and perpendicular to the longitudinal direction. The transverse direction preferably runs parallel to the transverse direction or corresponds to the transverse direction. The access side preferably points in the vertical direction. The support rail base and the support rail side walls together form a wall which delimits a receiving space which is open at both longitudinal ends of the support rail and is suitable for receiving the current conducting rail. The support rail often has a cross section perpendicular to the longitudinal direction, which is formed in the manner of a U-shape, so that the receiving space is not only open at the longitudinal ends of the support rail but also at a vertical end of the support rail. In the realization of a lamp by means of a generic system using the mounting body explained, the mounting body is usually mounted on the open vertical end of the mounting rail, so that the receiving space is vertically delimited by the mounting body on its side vertically opposite the base of the mounting rail. In order to realize a lamp, both the current conducting rail and the electrical functional elements are arranged in the receiving space. The mounting rail is usually fastened to a structure via its mounting rail base. The luminaire, which is realized by means of a generic system, usually has an interior space which is formed by the named receiving space of the mounting rail, the interior space being delimited by the mounting rail and mounting body with respect to the transverse direction and with regard to the vertical direction, and in the longitudinal direction is limited by mounting rail protective caps, which are arranged at the longitudinal ends of the mounting rail to realize the lamp, so that a protected interior space is formed for the functional elements. The support rail and the mounting body are generally usually produced separately from one another, support rail and/or are particularly preferred Assembly body j ewei ls made of sheet metal by forming. In order to implement a lamp, the mounting body is preferably held on the mounting rail by a retaining spring. For this purpose, the carrier rail usually has a side wall projection on the inner sides of its carrier rail side walls facing each other, the retaining spring being firmly connected to the mounting body and having elastically deflectable retaining projections at its transversal end when it is connected to the mounting body Cal assembly movement of the assembly body with the retaining spring attached to it can be elastically deflected towards one another in the transverse direction while they are being moved past the side wall projections of the support rail side walls, after which they grip behind these side wall projections under elastically conditioned restoring and thus elastically conditioned moving away from one another in the transverse direction, whereby the mounting body can be held reliably on the support rail. The contact device is preferably fastened to the mounting body and is electrically conductively connected to at least one electrical functional element, which is also fastened to the mounting body. The mounting body, contact device, current conducting rail and support rail are preferably designed to correspond to one another in such a way that during the assembly movement, contact fingers of the contact device are inserted into channels in the current conducting rail and the functional element is thus electrically connected via the contact device to at least some of the conductor wires arranged in the current conducting rail becomes . For example, the side wall projections of the support rail side walls can be formed by reshaping the support rail side walls. In order to implement a lamp, it is first necessary for the system to be in an installed state in which the current-carrying rail is arranged in the receiving space formed by the mounting rail and is fastened to the mounting rail. Embodiments are known in which the current conducting rail is fastened to at least one of the side walls of the mounting rail. The conductor rail is often fastened to the base of the mounting rail. In any case runs in the assembled state of the system, which describes a specific arrangement of components of the system relative to one another, the conductor rail extends in the longitudinal direction within the receiving space delimited by the wall of the mounting rail. A structure is thereby provided by the mounting rail and current-conducting rail, which allows the positioning of the functional element and the electrical supply of functional elements along the extension of the current-conducting rail and mounting rail. In the assembled state, the conductor rail usually extends over at least 80%, in particular at least 90%, in particular at least 95% of the longitudinal extension of the mounting rail. The current conducting rail is usually made of plastic, in particular by means of an extrusion or injection molding process.

A generic system is particularly preferably used to implement such an elongated lamp, in which at least two lamp assemblies are arranged one behind the other in the longitudinal direction. Each of the lamp assemblies includes a mounting rail and a current-conducting rail, which are arranged relative to one another as explained with regard to the assembled state of the system. The two lamp assemblies are connected to one another by the mounting rails being mechanically connected to one another by means of a coupling and the conductor rails being connected to one another at their ends pointing towards one another by means of an electrical connector, which in each case has a conductor wire which is arranged in the conductor rail of one of the lamp assemblies, with a lead wire, which is arranged in the current conducting rail of the other lamp assembly, electrically conductively connects. In order to ensure the desired modularity of the system, the mounting rail and power rail of a generic system must be designed in such a way that they can form a lighting assembly that has a receiving space that can be closed at the longitudinal ends, and on the other hand connected to another lighting assembly as explained can be, in which case the two lamp assemblies each form an accommodation space, the accommodation spaces being connected to one another and together forming an overall accommodation space, which is to be closed at its longitudinal ends so that a closed interior of a lamp can be realized. In this context, it is essential that such an interior space is sufficiently sealed off for the realization of a lamp, at least in accordance with the IP20 standard, preferably to prevent the ingress of dust. Such an interior preferably meets at least the requirement according to standard IP5X and thus standard IP50, in particular according to IP6X and thus standard IP60 (according to DIN EN60529). In addition, it must be ensured that the conductors routed in the conductor rails can be easily contacted by a contact device and the conductor rails can be connected to one another simply by means of an electrical connector and that a voltage breakdown between two conductor wires, especially at the longitudinal ends of the conductor rails, is prevented. In addition, such a system should have a modular structure that is as flexible as possible, so that a wide variety of connection positions for feeding in external energy supply is possible. These complex and diverse requirements for generic systems mean that generic systems are usually either complicated or not adequately protected. For example, it is known to provide such mounting rail protective caps on the longitudinal ends of a mounting rail to close the receiving space at its longitudinal ends, which are held on the mounting rail by retaining springs, which requires a complicated construction of the retaining springs or the protective caps and a complicated design on the mounting rail, since Retaining springs, protective caps and mounting rails must be designed to correspond to one another in order to enable the mounting rail protective caps to be adequately fixed to a mounting rail. It is also known to design current-conducting rails at their longitudinal ends in such a way that their conductors are sufficiently insulated from one another by the current-conducting rail itself, even at the longitudinal ends, which, however, makes it difficult for the conductors to make contact with an electrical connector as explained above.

The object of the present invention is to provide a system that has at least one disadvantage of the generic type systems at least partially fixed. Furthermore, the invention is based on the object of providing at least one method for realizing a lamp by means of a system and/or components of a system in order to at least partially eliminate at least one disadvantage of generic systems.

As a solution to the described problem underlying the invention, the invention proposes a system with the features according to claim 1 .

The system according to the invention is designed to realize a lamp that is elongated in the longitudinal direction. The system comprises at least one longitudinally elongate support rail and one longitudinally elongate power conducting rail. The system preferably comprises a plurality of mounting rails and a plurality of current-conducting rails, it being possible for each of the mounting rails and each of the current-conducting rails in embodiments according to the invention to have features that are described here in connection with embodiments according to the invention with reference to a mounting rail or with reference to a current-conducting rail. The current conducting rail has channels running in the longitudinal direction, in each of which at least one conductor wire is arranged. The channels are preferably arranged next to one another in a rowing direction which is perpendicular to the longitudinal direction, preferably the rowing direction runs in the transverse direction. The current conducting rail can, of course, also have further channels in which no conductor wire is arranged, with all channels, i.e. both the channels in which conductor wires are arranged and the further channels, running in the longitudinal direction, preferably being of the same design, and one behind the other in the direction of rows are arranged. The mounting rail has a mounting rail base and two mounting rail side walls extending away from the mounting rail base in a vertical direction and spaced apart from one another in a transverse direction by the mounting rail base. Vertical direction and transverse direction are perpendicular to each other and perpendicular to the longitudinal direction. The The base of the mounting rail and the side walls of the mounting rail form a wall that delimits a receiving space that is open at both longitudinal ends of the mounting rail for receiving the current-carrying rail. In an assembled state of the system, in which case a certain state of the system describes a certain arrangement of components of the system relative to one another, the current conducting rail is arranged in the receiving space and fastened to the mounting rail. The current conducting rail is preferably fastened to the mounting rail in such a way that a relative movement of the mounting rail and current conducting rail to one another along the transverse and vertical directions is avoided. The longitudinal mobility of the current conducting rail relative to the mounting rail is preferably limited, in particular to less than 5% of the longitudinal extent of the current conducting rail. The channels of the current conducting rail are preferably open on an access side of the current conducting rail, the current conducting rail being fastened to the mounting rail with its side facing away from the access side, particularly preferably being fastened to the bottom of the mounting rail. The access side preferably points in the transverse direction or in the vertical direction. In the assembled state, the current conducting rail is preferably fastened to the support rail base and points the access side away from the base in the vertical direction. The support rail preferably has a U-shaped cross-section perpendicular to the longitudinal direction, with the access side facing the open side of the U. The system according to the invention can in particular have further features which are described in connection with generic systems. In one embodiment, the system has a mounting rail protective cap which can be pushed onto each of the longitudinal ends of the mounting rails at the longitudinal ends in order to close the receiving space. The system particularly preferably has a plurality of these mounting rail protective caps, which are therefore each of identical design, with one of the mounting rail protective caps being able to be pushed onto one longitudinal end of the mounting rail in each case, depending on the installed state. Through the pin up the mounting rail protective caps on the longitudinal ends of the mounting rail, the receiving space can be closed in the longitudinal direction, so that the mounting rail protective caps with their inner sides pointing to one another in the longitudinal direction, the mounting rail side walls with their inner sides pointing to one another in the transverse direction and the mounting rail base with its inner side facing the mounting rail side walls together delimit an interior space, in which, for example, as explained above, at least one electrical functional element of the lamp can be arranged to realize a lamp, with this interior preferably being able to be delimited by a mounting body at its end opposite the mounting rail base in the vertical direction, as explained above. In one embodiment, the system has a current-conducting rail protective cap, which is designed to be slipped onto a longitudinal end of the current-conducting rail, with insulation of the line wires from one another. For example, the conductor rail protective cap can only cover the line wires at its longitudinal end in order to prevent the line wires from being able to be contacted from its longitudinal end and thus avoid contact occurring in the longitudinal direction Line-up direction adjacent line wires, so that the line wires are insulated with respect to the line-up direction by the support rail protective cap.

In an embodiment according to the invention, the mounting rail protective cap has a first holding contour. Furthermore, each longitudinal end of the support rail is formed by a respective longitudinal end region of the support rail, which has a second holding contour. Each of the two longitudinal end regions, which form the two opposite longitudinal ends of the support rail in the longitudinal direction, thus has such a second holding contour. Each of the holding contours, ie the first and second holding contour, has a gripping section and a pressing section, the pressing section being in a direction perpendicular to the longitudinal direction extending locking direction is spaced from the rear grip portion. The support rail protective cap is designed to correspond to the support rail in such a way that it can be fastened to the longitudinal end section forming this longitudinal end in an operating position in order to close one of the longitudinal ends, with the holding contours being brought into engagement in such a way that the holding contours press against one another with their pressing sections along the blocking direction and the gripping section of the support rail protective cap is longitudinally further spaced from the longitudinal end of the support rail than the gripping portion of the support rail and overlaps with it in the locking direction. Each of the holding contours thus has a gripping section and a pressing section spaced apart from this gripping section along the blocking direction. Because the pressing sections of the two holding contours press against each other in the operating position in the blocking direction and the gripping sections of the holding contours overlap in the blocking direction, the mounting rail protective cap is particularly reliably fixed to the mounting rail in the operating position, since this ensures that the overlapping of the gripping sections in the blocking direction is reliable is present and can only be canceled by a relative force acting against the pressing force between the rear grip sections. The operating position denotes a defined position of the mounting rail protective cap relative to the mounting rail. In the operating position, the support rail protective cap is preferably fixed to the support rail in such a way that it is held in a fixed position on the support rail in the longitudinal direction and only relatively when a considerable force is applied, which is preferably at least 20 N, in particular at least 40 N, and which acts in the longitudinal direction can be moved to the mounting rail. The blocking direction particularly preferably runs in the vertical direction or in the transverse direction, particularly preferably in the vertical direction. The support rail protective cap particularly preferably has a stop which, in the operating position, bears against the longitudinal end of the support rail, which it closes in the operating position. Particularly preferably presses the support rail protective cap in the operating position with the stop with a pressing force acting in the longitudinal direction against the longitudinal end of the support rail. In the operating position, the mounting rail protective cap generally preferably closes at least 70%, in particular at least 80%, in particular at least 90% of the clear cross section of the mounting rail, which is delimited by the mounting rail bottom and the mounting rail side walls.

In one embodiment of the system according to the invention, the conductor wires arranged in the channels of the current conducting rail are accessible from both longitudinal ends of the current conducting rail, with the current conducting rail forming a first connector face at its first longitudinal end and a second connector face that is different from the first connector face at its second longitudinal end. The mating faces of the conductor rail are formed by their contour. For example, the current conducting rail has a rear gripping device at each longitudinal end, via which the current conducting rail can be brought into engagement with a power conducting rail adjacent in the longitudinal direction and/or a mounting rail protective cap, with the rear gripping devices of the two connector faces being different from one another. In general, the channels are preferably arranged asymmetrically with respect to the center of the current-carrying rail, in relation to the line-up direction. This can prevent incorrect insertion of, for example, a contact device or an electrical connector when plugged onto the current-conducting rail or its conductors. For example, the connector faces can differ due to the asymmetrical arrangement of the channels, since each connector face then has a different shape when looking at the respective connector end along the longitudinal direction. For example, the channels of the current-conducting rail can be open at the longitudinal ends, so that contact can be made directly with the conductors in the channels. For example, the line wires can protrude beyond the current-conducting rail at the longitudinal ends, so that they are accessible at the longitudinal end of the current-conducting rail and can therefore be contacted. The accessibility of the lead wires from the longitudinal end of the Conductor rail from simplifies the connection of the conductor rails of the conductor rail, for example to an electrical connector. In a preferred embodiment, the system has a conductor rail protective cap, the conductor rail protective cap having two longitudinal ends that are designed differently and of which a first longitudinal end is designed to correspond to the first connector face and a second longitudinal end to the second connector face in such a way that the conductor rail protective cap is connected to its first end can be plugged onto the first longitudinal end of the current conducting rail in a first protective position while insulating the line wires at the first end of the current conducting rail and can be plugged with its second end onto the second longitudinal end of the current conducting rail in a second protective position while insulating the line wires at the second end of the current conducting rail. The current conducting rail protective cap can thus have a first plug face at the first longitudinal end and a second plug face at the second longitudinal end, the first plug faces of the current conducting rail and current conducting rail protective cap being designed to correspond to one another and the second plug faces of the current conducting rail and current conducting rail protective cap being designed to correspond to one another. For example, the conductor rail protective cap can be configured at its respective longitudinal end in such a way that it corresponds to the respective longitudinal end of the conductor rail in such a way that it covers the line wires at their longitudinal ends in their respective protective position and/or extends between two line wires that are adjacent to one another in the line up direction in order to insulate them from one another . Since the conductor rail protective cap is designed in such a way that each of its longitudinal ends is designed to correspond to one of the two connector faces of the conductor rail, a conductor rail protective cap can be arranged at each longitudinal end of the conductor rail, with insulation of the line wires at the longitudinal end of the conductor rail, with the conductor rail protective cap on the two longitudinal ends the conductor rail arranged with their respective other longitudinal ends is. The provision of such a current-conducting rail protective cap can, in a particularly simple manner, enable protection of the conductors at the ends of the current-conducting rail in a particularly effective manner, in particular while avoiding electrical breakdown between adjacent conductors and/or between components arranged at the longitudinal end of the current-conducting rail, a lamp or a lamp assembly and at least one of the lead wires. The provision of a conductor rail protective cap according to the invention is also advantageous in a system independently of the provision of at least one mounting rail protective cap, but particularly advantageous together with the provision of at least one mounting rail protective cap, in particular according to another embodiment of the invention. Generally preferably, the current-conducting rail protective cap has a maximum of one tenth, in particular a maximum of one twentieth, of the longitudinal extent of the current-conducting rail in the longitudinal direction. The conductor rail protective cap generally preferably extends in the longitudinal direction by a maximum of 7 cm, in particular a maximum of 5 cm.

In one embodiment, the mounting rail protective cap, the current conducting rail protective cap, the mounting rail and the current conducting rail are designed to correspond to one another in such a way that, starting from the assembled state, one of the current conducting rail protective caps is attached to both longitudinal ends of the current conducting rail to implement an operating state of the system while maintaining the attachment of the current conducting rail to the mounting rail and one of the mounting rail protective caps can be plugged onto each of the two longitudinal ends of the mounting rail. The system generally preferably comprises a plurality of mounting rail protective caps and a plurality of current conducting rail protective caps, each of which has features that are described here with reference to embodiments according to the invention with reference to a mounting rail protective cap or a current conducting rail protective cap. The system preferably has a number of identically designed support rail protective caps and a number of identically designed current conducting rail protective caps. When the system is in operation, the mounting rail protective cap is particularly preferably located at each longitudinal end of the mounting rail in the operating position explained above and the current-conducting rail protective cap is in its first protective position at the first longitudinal end of the current-conducting rail and in its second protective position at the second longitudinal end of the current-conducting rail ition . This design of the system allows an operating state to be achieved, in particular by realizing a lighting assembly, in which the receiving space is reliably closed at both of its longitudinal ends by the mounting rail protective caps and in which the conductors on the longitudinal ends of the conductor rail are reliably protected against incorrect contacting and / or unwanted contact and / or electrical breakdown are protected. In a particularly advantageous embodiment, the mounting rail protective cap arranged at a first longitudinal end of the mounting rail rests against the current conducting rail protective cap arranged at the first longitudinal end of the current conducting rail and the mounting rail protective cap arranged at the second longitudinal end of the mounting rail rests against the current conducting rail protective cap arranged at the second longitudinal end of the current conducting rail.

In one embodiment, the retaining contours are designed to correspond to one another in such a way that the mounting rail protective cap can be fastened to the longitudinal end section by being pushed onto the longitudinal end of the mounting rail in a plugging direction in order to realize its operating position. The first retaining contour formed by the mounting rail protective cap and the second retaining contour formed by the mounting rail can thus be brought into engagement with their rear grip sections simply by performing a relative movement of the mounting rail and mounting rail protective cap to one another at the longitudinal end of the mounting rail in the plugging direction, so that the Mounting rail protective cap on the mounting rail is fixed in position by engaging, in particular in position with respect to all three directions in space. The insertion direction preferably runs in the longitudinal direction. The retaining contours of the mounting rail and the mounting rail protective cap are particularly preferred in relation to one another Correspondingly designed so that the support rail protective cap, starting from its operating position, can only be detached from the longitudinal end of the support rail by a releasing force applied to it counter to the direction of insertion, the amount of which is at least 20 N, in particular at least 25 N, in particular at least 30 N is at least 50 N. In general, the mounting rail protective cap is preferably firmly fixed to the mounting rail in the operating position in such a way that it can only be detached from the mounting rail in the opposite direction to the plug-in direction, in which the other two spatial directions are perpendicular to the plug-in direction, which of course are perpendicular to one another, j However, it cannot be detached from the mounting rail, so that it can only be released from its position and removed from the mounting rail by a relative movement in the opposite direction to the mounting rail. The insertion direction preferably runs in the longitudinal direction, with the mounting rail in the operating position enclosing the mounting rail protective cap transversally and vertically at each of its transverse ends and next to its vertical ends, at least in sections, and with the mounting rail protective cap in a direction along the longitudinal direction with a stop on the longitudinal end of the The carrier rail rests against a relative movement to the carrier rail in a first direction along the longitudinal direction, and the rear grip sections of the carrier rail and carrier rail protective cap overlap perpendicularly to the longitudinal direction, preventing a relative movement of the carrier rail protective cap to the carrier rail in a second direction, opposite the first, along the longitudinal direction. The mounting rail protective cap particularly preferably has a covering section which, in the operating position, covers at least 80% of a cross-sectional area delimited by the mounting rail base and mounting rail side walls and thus an internal cross-section enclosed at least in sections by the mounting rail base and mounting rail side walls, with the cross section being perpendicular to the longitudinal direction extends . The covering section preferably covers at least 90% of the cross-sectional area mentioned. Thus, the clear cross-section enclosed by the wall is at the longitudinal end of the support rail in any case largely covered by the mounting rail protective cap in the operating position, which ensures protection of the receiving space closed by the mounting rail protective cap. At least one, preferably at least two, break-out sections are preferably provided in the cover section. Such a break-out section can easily be broken out of the rest of the cover section; in particular, a thinning of the material surrounding the break-out section, ie a dividing line with a reduced wall thickness, is provided in the cover section for this purpose. By breaking out the break-out section, a break-out opening can be realized in the cover section, through which, in the operating position of the mounting rail protective cap, a supply cable can be routed from the outside through the mounting rail protective cap into the receiving space. In one operating state, the break-out section is preferably removed from the remaining cover section and a sealant, for example an elastomer ring, is provided in the resulting break-out opening, with a supply cable being guided through the break-out opening and the sealant enclosing the supply cable and with an edge surrounding the break-out opening of the cover section connects, so that the supply cable is connected to the cover section by the sealant, in particular via a friction fit. The inventors have recognized that the special design of the retaining contours themselves allows the cable bushing to be provided in the cover section, with the associated loading of the cover section, without having to expect the mounting rail protective cap to detach from the mounting rail in normal applications.

In one embodiment, the mounting rail protective cap, in the operating position, covers the mounting rail side walls and/or the mounting rail bottom at the longitudinal end of the mounting rail, which is formed by the longitudinal end region to which it is attached. The mounting rail protective cap thus runs perpendicularly to the longitudinal direction over the extent of the mounting rail side walls and/or the mounting rail base. On the one hand, this can improved sealing between the mounting rail protective cap and the wall of the mounting rail can be made possible, on the other hand, a longitudinal position of the mounting rail can be defined particularly reliably in its operating position, in particular together with the provision of the rear grip sections, which overlap or overlap in the operating position. back to back . The area of the mounting rail protective cap with which it covers the mounting rail side walls and/or the mounting rail base at the longitudinal end is preferably formed directly adjacent to the covering section. The covering section is preferably formed by a plate-like section of the mounting rail protective cap, which extends perpendicularly to the longitudinal direction over the mounting rail side walls and/or the mounting rail bottom, concealing these. The support rail protective cap preferably lies against the longitudinal end in the longitudinal direction. The support rail protective cap particularly preferably extends in the vertical direction and/or in the transverse direction beyond the longitudinal end of the support rail and thus at this longitudinal end beyond the extension of the support rail in the respective direction. This ensures a reliable stop between the mounting rail and the mounting rail protective cap and also a particularly reliable seal.

In one embodiment, the retaining contours are designed to correspond to one another in such a way that, after it has been fastened to the longitudinal end section of the mounting rail, the mounting rail protective cap can only be detached from the mounting rail with elastic deformation. Thus, at least one of the retaining contours, preferably the first retaining contour formed by the support rail protective cap, is designed to be elastically deformable, with the overlapping of the rear grip sections starting from the operating position being resolved or expanded as a result of the elastic deformability. can be eliminated, and after the resolution of the overlap of the Hintergri ff sabschnitte or. during this overlap is resolved, the mounting rail protective cap can be detached from the mounting rail, in particular by relative movement opposite to the insertion direction.

In one embodiment, the gripping section formed by the support rail is formed by an embossing stamped into the wall. The wall is particularly preferably closed over the embossing, so that the gripping section formed by the mounting rail is formed in a closed wall section. The implementation of the gripping section by means of the embossing can allow the wall of the support rail to close the receiving space within the entire extension of the second holding contour and thus enclose the receiving space without an opening provided in the wall, which can particularly promote sealing of the interior. The wall is particularly preferably made of sheet metal and the embossing is formed by forming the sheet metal. The embossing is particularly preferably formed at least in sections in the base of the mounting rail. The embossing can be a continuous embossing or have several partial embossings spaced apart from one another. The embossing can be in the form of a projection or indentation formed on the inside of the wall. Forming the embossing with a depression has proven to be particularly advantageous, since such an embossing is particularly easy to implement and the outside of the wall can be made as smooth as possible in the simplest possible way, ie with as little unevenness as possible that is visible from the outside is, which can be advantageous both for the optical design and for avoiding the accumulation of dirt. The embossing is generally preferably at least partial, in particular at least 70% of the depth of the embossing is formed by reducing the wall thickness of the wall. Of course, the wall thickness designates the extent of the wall perpendicular to its areal extent, with which it delimits the receiving space. The wall thickness preferably corresponds to the extension of the wall in the pressing direction. Particularly preferably, the embossing has a depth of less than 1 mm, in particular less than 0.5 mm, in the pressing direction. Particularly preferably, the wall is level with the embossing a wall thickness of less than 1 mm, in particular less than 0.8 mm, in particular less than 0.6 mm, in particular less than 0.5 mm, in particular less than 0.4 mm. This is based on the wall thickness in the area of the embossing in which the embossing has its maximum depth. The depth of the embossing refers to a step in the wall that is provided by the embossing. Correspondingly, the depth of the embossing defines the extension of the gripping section in the pressing direction. In the operating position, the gripping section formed by the support rail protective cap particularly preferably extends over more than 50%, in particular more than 70%, in particular more than 90% of the depth of the embossing, of course with reference to the pressing direction. In the operating position, the gripping sections preferably overlap along a distance in the pressing direction that is less than 0.8 mm, in particular less than 0.5 mm, in particular between 0.2 mm and 0.5 mm. The depth of the embossing is generally preferably an extension of the embossing in the pressing direction. Generally preferably, the embossment is immediately adjacent to a wall portion of the wall, with the bottom of the embossment being spaced from the adjacent wall portion along the pressing direction by the depth of the embossment.

The wall section preferably borders the embossing on only one side; in one embodiment, the wall section borders the embossing in several directions, in particular it encloses the embossing in an uninterrupted closed manner. Generally preferably, the wall in the wall section immediately adjacent to the embossing has a wall thickness of less than 1 mm, in particular less than 0.8 mm, in particular less than 0.7 mm, in particular between 0.5 mm and 0.7 mm.

Particularly preferably, the embossing has a width running perpendicularly to its depth, which is at least twenty times, in particular at least fifty times, its depth, in particular at least 5 mm, in particular at least 10 mm. The embossing is particularly preferably provided in the mounting rail base, with the depth running in the vertical direction and the width running in the transverse direction. The depth is based on the maximum depth with a varying depth, and the width is based on the total width, and if an embossing with a plurality of partial embossings is provided, it is therefore based on the common extension all partial embossings together. The embossing generally preferably has a depth that changes along the longitudinal direction over at least 50%, in particular at least 70% of the longitudinal extent of the embossing, the depth increasing with increasing distance from the longitudinal end of the mounting rail formed by the longitudinal end region within which the embossing is formed decreases along the longitudinal direction. The depth of the embossing preferably decreases continuously in this longitudinal extension area with increasing distance from the longitudinal end. Particularly preferably, the depth at a first longitudinal end of the embossing, with which it forms the gripping section of the support rail, is dimensioned as explained above, providing a gripping section with sufficient extension in the pressing direction, whereas the depth at the second longitudinal end, opposite the first longitudinal end in the longitudinal direction, of the Embossing is less than a third, in particular less than a fifth of the depth at the first longitudinal end, with the embossing preferably merging continuously at its second longitudinal end, ie with a depth equal to zero, into an immediately adjacent wall section of the wall.

In one embodiment, the mounting rail protective cap is delimited along the pressing direction by two pressing direction ends, one of the pressing direction ends being that of the mounting rail protective cap formed rear grip section and the other of the pressing direction ends formed by the support rail protective cap pressing section. Since the pressing section and gripping section are formed at two ends of the mounting rail protective cap in the pressing direction, they can be formed particularly easily with a specific contour and can also be specifically adapted to the retaining contour formed by the mounting rail. An end of the pressing direction is not necessarily the absolute end of the mounting rail protective cap in the pressing direction, but in any case forms an end of the mounting rail protective cap in sections, based on the pressing direction.

In one embodiment, the first retaining contour formed by the mounting rail protective cap has a plug-in section which, in the operating position, is arranged in the receiving space formed by the mounting rail. The plug-in section particularly preferably forms the gripping section formed by the support rail protective cap. Generally preferably, the mounting rail and mounting rail protective cap overlap at one longitudinal end of the mounting rail, which is thus directed in a specific direction along the longitudinal direction, exclusively with their gripping sections. In general, the gripping sections in the operating position are preferably arranged exclusively inside the receiving space. In the embodiment in which the mounting rail protective cap has the aforementioned plug-in section, the plug-in section preferably has two side walls and a base connecting the side walls on its outside, with each of the side walls resting against one of the mounting rail side walls in the operating position of the mounting rail protective cap and the base against the support rail bottom. The base of the plug-in section is preferably spaced at least 70%, in particular at least 80% of its extension in the transverse direction by less than 0.5 mm, in particular less than 0.3 mm from the carrier rail base. The side walls of the plug-in section are particularly preferably less than 0.5 mm, in particular less than 0.3 mm, from them over at least 70%, in particular at least 80% of their extension in the vertical direction each associated mounting rail side wall spaced. In this way, a particularly good seal and fixation of the mounting rail protective cap relative to the mounting rail in its operating position can be ensured.

In one embodiment, the first retaining contour formed by the mounting rail protective cap forms an overlapping section with which it runs along the outside of the wall. While the wall faces the receiving space with its inside and delimits it, it faces away from the outside space with its outside. By the mounting rail protective cap running at least in sections along the outside of the wall with its holding contour, a particularly good sealing and fixing of the mounting rail protective cap to the mounting rail in the operating position can be achieved. Particularly preferably, the overlapping section runs from the longitudinal end of the support rail, on which it is arranged in the operating position, along the outside of the wall to the section of the wall in which the wall forms the first grip section on its inside. The mounting rail protective cap particularly preferably runs with its first retaining contour in a section of the wall along the outside of the wall, in which the wall forms the first gripping section on its inside. In this way, a particularly reliable safeguarding of the meshing of the gripping sections can be guaranteed. The overlapping section of the retaining contour preferably extends along the base of the mounting rail. The overlapping section preferably has an area of at least 3 cm ² , ie the holding contour extends over at least 3 cm ² , as explained, on the outside of the wall.

In one embodiment, the pressing section formed by the support rail protective cap includes a projection protruding along the pressing direction. The pressing section is particularly preferably formed by one or a plurality of such projections. The projection is thus in the pressing direction compared to sections of the DIN rail protective cap that are adjacent perpendicular to the pressing direction. The support rail protective cap particularly preferably has a web section which extends in the longitudinal direction and on which the projection is arranged. The web section particularly preferably extends in the longitudinal direction away from the cover section explained above. The mounting rail protective cap particularly preferably has the plug-in section explained, which has side walls and base, the pressing section formed by the mounting rail protective cap comprising at least two projections which are each formed on one of the side walls. The projections can extend in the transverse direction away from the side walls and are preferably designed as projections protruding along the pressing direction. Particularly preferably, the at least one projection protruding in the pressing direction has an insertion bevel, with its extent increasing in the pressing direction along the longitudinal direction. Thus, the projection is preferably designed to slide along a section of the mounting rail when the mounting rail protective cap is placed in the longitudinal direction on the longitudinal end of the mounting rail, increasing the contact pressure between itself and the section of the mounting rail. The section of the support rail is particularly preferably formed by a projection which is formed on a support rail side wall.

In one embodiment, the gripping section formed by the mounting rail is formed in the base of the mounting rail, the mounting rail side walls each having a projection running in the transverse direction, the projections together forming the first pressing section, the pressing direction running in the vertical direction. The projections formed by the mounting rail side walls are particularly preferably designed to correspond to the projections formed by the pressing section of the mounting rail protective cap. The projections of the pressing sections of the mounting rail protective cap and the mounting rail are preferably designed to correspond to one another in such a way that under elastic deflection of the projection of the Pressing section of the support rail protective cap when the support rail protective cap is placed on the support rail in the longitudinal direction until the operating position is reached, an increasing pressure force is generated between the projections, while the projections slide along one another.

Generally preferably, in the operating position, only the rear grip sections overlapping perpendicularly to the longitudinal direction limit a longitudinal displaceability of the mounting rail protective cap relative to the mounting rail in a specific direction along the longitudinal direction. As a result, a targeted limitation of the longitudinal displacement can be guaranteed and, in particular, a targeted release force can be specified or a targeted release movement can be specified, with which the support rail protective cap can be detached from the support rail, starting from the operating position and overcoming the overlap of the rear gripping sections.

In one embodiment, the conductor rail protective cap has a first longitudinal end area forming the first longitudinal end and a second longitudinal end area forming the second longitudinal end. The conductor rail protective cap has channel sections running next to one another in the longitudinal direction in each of the two longitudinal end regions, the first longitudinal end region of the conductor rail protective cap being pluggable onto the first plug-in face of the conductor rail, with the accommodation of first conductor wire ends of the conductor wires arranged in the conductor rail in the channel sections of its first longitudinal end area, and wherein the conductor rail protective cap can be pushed with its second longitudinal end area onto the second plug-in face of the current conducting rail, receiving second conductor wire ends of the conductor wires arranged in the conductor rail in the channel sections of its second longitudinal end area. In the particularly preferred embodiment, the longitudinal ends of the conductor rail protective cap are thus in such a way corresponding to the connector faces or Longitudinal ends of the conductor rail formed that s in the protective position Lead wires are accommodated with their ends in the channel sections and are thus electrically insulated from one another by the channel walls of the respective channel section, which form the channel sections between them. The channel sections are sections of a channel which runs longitudinally and is thus adapted to receive a longitudinally running longitudinal end region of a conductor wire. In the protective position, a channel wall of the channel section runs on each side, relative to the line-up direction, of a line wire on which an adjacent line wire is arranged. The inventors have recognized that the provision of channel sections in the conductor rail protective cap can ensure that the ends of the conductors are held and insulated in a particularly reliable manner. The inventors have found that in particularly simple embodiments it is even possible for the channel sections formed by the conductor rail protective cap to be open at their longitudinal ends facing away from the line wire ends in the protective position, because of the channels themselves and the distance between the line wire ends and the line wire ends facing away from them Longitudinal end of the channel sections adequate insulation can be ensured. In the protective position, the line wire ends are preferably spaced at least 20%, in particular at least 30% of the longitudinal extension of the conductor rail protective cap from the longitudinal end of the channel sections facing away from them in the longitudinal direction, in particular at least 3 mm, in particular at least 5 mm in the longitudinal direction from this longitudinal end of the channel sections .

In one embodiment, the conductor rail protective cap can be pushed with each of its longitudinal ends onto the associated longitudinal end of the conductor rail in such a way to achieve the respective protective position that the channel sections formed in their respective longitudinal end area overlap with the channels of the conductor rail in the longitudinal direction and together with them via a transition between the conductor rail and conductor rail protective cap in the longitudinal direction away form uninterrupted overall channels. Because the channel sections of the current-conducting rail protective cap are arranged so that they overlap with the channels of the current-conducting rail in the longitudinal direction, a particularly reliable, continuous electrical insulation of the line wires from one another and from the environment can be ensured. At this point, it should be pointed out that the channel sections are generally preferably arranged next to one another in the rowing direction, analogous to the channels of the current-conducting rail, and run elongated in the longitudinal direction, with them preferably being open on an access side running perpendicular to the rowing direction and perpendicular to the longitudinal direction. The access side of the current-conducting rail protective cap preferably points in the same direction as the access side of the current-conducting rail or in the opposite direction to this.

In one embodiment, the first and second channel sections are arranged in alignment with one another. Preferably, the first and second channel sections together form continuous channels of the conductor rail protective cap in the longitudinal direction. The inventors have recognized that the aligned arrangement of the channel sections, in particular the continuous configuration of the channels, is particularly easy to produce and that when the protective cap for the current-conducting rail is attached to a longitudinal end of the current-conducting rail, adequate insulation of the conductors at the end of the current-conducting rail is ensured. In general, the conductor rail protective cap forms a different plug face at each of its longitudinal ends, with the plug faces in particular differing at least in that when looking at the respective longitudinal end of the conductor rail protective cap along the longitudinal direction, the plug faces are configured asymmetrically, in particular are formed inverted to one another. The connector faces of the conductor rail protective cap preferably differ analogously to the connector faces of the conductor rail.

In one embodiment, the longitudinal end portions of the Conductor rail protective cap formed in such a way corresponding to the longitudinal ends of the conductor rail that in the protective position the conductor rail and the conductor rail protective cap encompass each other transversally. In the first protective position, the current-conducting rail preferably encompasses the current-conducting rail protective cap transversally, and in the second protective position the current-conducting rail protective cap encompasses the current-conducting rail transversally. The transversal gripping can ensure a particularly reliable fixing of the current-conducting rail protective cap and current-conducting rail to one another. By in a protective position the Stromleitschiene the Stromleitbahnen protective cap and in the other protective position the Stromleitbahnen protective cap encompasses the Stromleitschiene transversally, the Stromleitbahnen protective cap can be plugged onto the corresponding longitudinal end of the Stromleitschiene particularly easily and without errors. It is generally preferred that the current-conducting rail protective cap has, at its first longitudinal end, a first rear-engagement device which is designed to correspond to a first rear-engagement device formed at the first longitudinal end of the current-conducting rail. Particularly preferably, the current-conducting rail protective cap has a second rear-engagement device on its second longitudinal end, which is designed to correspond to a second rear-engagement device formed on the second longitudinal end of the current-conducting rail. The rear-engagement device or rear-engagement device can be formed by the respective plug-in face of the current-conducting rail protective cap or current-conducting rail. Rear grip device and corresponding rear grip device are preferably designed to correspond to one another in such a way that in the protective position of the current conducting rail protective cap, which the current conducting rail protective cap occupies, when its corresponding rear grip device assigned to the protective position engages behind the corresponding rear grip device of the current conducting rail, they limit the longitudinal displaceability of the current conducting rail protective cap and current conducting rail relative to one another in the longitudinal direction. Preferred is by interlocking Rear grip device and rear grip device set the longitudinal position of the current conduction rail protective cap for current conduction rail. Particularly preferably, the rear grip device and rear grip device are designed to correspond to one another in such a way that they can only be detached from one another by elastic deformation of the current conducting rail protective cap and/or current conducting rail, starting from the protective position. Particularly preferably, the first gripping device is formed on a transversal outer side or on at least one first holding arm that transversally encompasses the current-conducting rail at its first longitudinal end in the first protective position. Particularly preferably, the second rear grip device is formed on a vertical outer side or on at least one second holding arm that vertically encompasses the current conducting rail in the second protective position at its second longitudinal end. A transversely or vertically encompassing holding arm runs on a transverse side or vertical side, ie transversely next to or vertically next to the current-conducting rail and overlaps with the current-conducting rail in the longitudinal direction. Preferably, the first rear-engagement device has two first holding arms, between which the current-conducting rail is arranged in the transverse direction and which encompass the current-conducting rail on both transverse sides. Preferably, the second rear grip device has one or more holding arms only on a vertical side of the current-conducting rail, preferably on the vertical side of the current-conducting rail facing away from the access side. A retaining projection is particularly preferably provided on the retaining arm, which engages with a retaining recess on the current conducting rail. Of course, in such a configuration, in which the rear grip device is formed on a transverse outer side or vertical outer side of the conductor rail protective cap, the conductor rails have a holding arm which, as explained with regard to the retaining arm of the conductor rail protective cap, encloses the conductor rail protective cap on this side, with this holding arm also being preferred a corresponding retaining projection can be formed, which engages in a recess provided on the outside in the protective position. In one embodiment, the current conducting rail comprises a plurality of current conducting profiles arranged one behind the other in the longitudinal direction, with two current conducting profiles arranged one behind the other in the longitudinal direction having mutually corresponding engagement devices on their mutually facing longitudinal end regions, which are brought into engagement in the assembled state and a longitudinal displaceability of the two adjacent current conducting profiles relative to one another on a specified Limit displacement range, of course based on a relative movement in the longitudinal direction. Each of the current conducting profiles is preferably configured in its first longitudinal end area in the same way as the current conducting rail in its first longitudinal end area and/or each of the current conducting profiles in its second longitudinal end area is configured in the same way as the current conducting rail in its second longitudinal end area. As a result, a contour can be formed particularly advantageously on a longitudinal end region of the current conducting rail and the current conducting profiles, which enables both a plug face corresponding to the current conducting rail protective cap and an engagement device for connecting two current conducting profiles arranged one behind the other in the longitudinal direction. Particularly preferably, at least some of the current-conducting profiles have in their first longitudinal end region a rear grip device designed similarly to the second rear grip device and/or have a rear grip device designed similarly to the first rear grip device on their second longitudinal end region. The rear engagement device formed by the respective current conducting profile can be encompassed by the engagement device formed by it. In this particularly preferred embodiment, the engagement devices can be designed to correspond to the engagement devices of the current-conducting rail protective cap, so that a current-conducting profile can be selectively engaged with its second longitudinal end with the first longitudinal end of an adjacent current-conducting profile in the longitudinal direction can be or can be brought into engagement with the second longitudinal end of the conductor rail protective cap. The inventors have recognized that this enables an analog structure of the engagement devices on the one hand and rear grip devices and rear grip devices on the other hand, which particularly simplifies and improves the production of the system.

Generally preferably, in the mounted state, the conductor wires protrude in the longitudinal direction beyond the current-conducting rail at at least one of the longitudinal ends of the current-conducting rail. In general, the mounting rail protective cap and the conductor rail protective cap can be connected to one another in two different positions relative to one another in a fixed position. Can be connected in a fixed position means that the mounting rail protective cap and conductor rail protective cap are captively held together. In a first relative position, the first longitudinal end of the conductor rail protective cap points away from the mounting rail protective cap in the longitudinal direction. In a second relative position, the conductor rail protective cap points with its first longitudinal end in the longitudinal direction towards the mounting rail protective cap. Correspondingly, in the first relative position, its second longitudinal end points towards the support rail protective cap and away from it in the second relative position. The inventors have recognized that in this way a component comprising a mounting rail protective cap and a current conducting rail protective cap can be realized in a particularly simple and cost-effective manner, which can be attached to both longitudinal ends of a lighting assembly, so that the mounting rail protective cap is in its operating position and the current conducting rail protective cap is in its respective protective position. For example, the conductor rail protective cap can be mounted on the support rail protective cap such that it can rotate, so that the two different relative positions can be realized by rotating the conductor rail protective cap. For example, a sliding guide can be provided between the mounting rail protective cap and current-carrying rail protective cap, which can be pulled off, then turned and put on again Conductor rail protective cap on the mounting rail protective cap enable the realization of the two different relative positions. Particularly preferably, the support rail protective cap and the current conducting rail protective cap can be pushed together in the first relative position onto the first longitudinal end of the support rail and current conducting rail and in the second relative position together onto the second longitudinal end of the support rail and current conducting rail, realizing the operating position of the supporting rail protective cap and realizing the respective protective position of the current conducting rail protective cap . Due to the fact that the mounting rail protective cap and conductor rail protective cap can be plugged on together, closing the receiving space based on the installed state of the system can be particularly simplified. Conductor rail protective cap and support rail protective cap can thus be plugged as a single component onto the respective longitudinal end of the support rail and current conductive rail, based on the assembled state of the system.

In one embodiment, the system includes a plurality of the support rails and a plurality of the power conduction rails, the system including a first and a second light assembly, each including one of the support rails and each of the power conduction rails. All mounting rails can each have features that are explained in connection with a mounting rail of an embodiment of a system according to the invention. Correspondingly, all current-conducting rails can have features that are described in connection with embodiments of the system according to the invention with reference to a current-conducting rail. All support rails of the system and all current-conducting rails of the system are preferably of identical design. Notwithstanding this, the system can, of course, also include additional mounting rails and additional current-carrying rails that are configured differently. The conductor rail of each lamp assembly is attached to the support rail of the respective lamp assembly. With each lighting assembly, the conductor rail and mounting rail are therefore in their Relative position to each other that they occupy when the system is assembled as explained above. In the preferred embodiment, the system also comprises a coupling, which has a coupling base and coupling side walls and can be inserted in the longitudinal direction into the mounting rail from each longitudinal end of each mounting rail. With its wall, the support rail preferably forms a guide into which the coupling can be inserted, at least with its coupling side walls, with the coupling being fixed in position on the support rail. The guide preferably has a vertically upper and a vertically lower guide end, with the coupling lying against the upper and lower guide end when inserted into the guide. When the system is assembled, the coupling is inserted into the first longitudinal end of the mounting rail of the first lamp assembly and inserted into the second longitudinal end of the mounting rail of the second lamp assembly, with the mounting rails of the lamp assemblies being fixed in position relative to one another. In the assembled state, the support rails particularly preferably lie against one another, in particular with their longitudinal ends facing one another, in particular directly against one another. In the assembled state, the conductor rails of the lamp assemblies are spaced apart from one another in the longitudinal direction, in particular by at least twenty times the distance that the support rails are spaced apart from one another in the longitudinal direction. Particularly preferred is an operating state of the system that can be implemented in which the mounting rails of the lighting assemblies are fixed in position to one another by the coupling, with the mounting rail protective cap being fixed in its operating position relative to this mounting rail at the second longitudinal end of the mounting rail of the first lighting assembly , a current conducting rail protective cap is fixed in its second protective position on the second longitudinal end of the current conducting rail of the first lighting assembly, a further supporting rail protective cap is fixed in its operating position relative to this supporting rail at the first longitudinal end of the supporting rail of the second lighting assembly and on the first longitudinal end of the current conducting rail of the second Light assembly another Stromleitbahnenschutz cap is fixed in its first protective position relative to this current conduction rail. Correspondingly, in the operating state, the interior space of a lamp can be limited by the two mounting rails of the lamp assemblies and the two mounting rail protective caps. This interior space can be open, for example, on the vertical side facing away from the mounting rail bases, so that electrical functional means can be brought into the interior space through this opening, for example by one or more mounting bodies being able to be fixed to this opening and thereby the interior space ießen this side, with the provision of several mounting bodies, the mounting bodies are arranged one behind the other in the longitudinal direction and are attached to one or both of the support rails, in particular by means of the retaining springs explained above.

In one embodiment, the system has an electrical connector whose first longitudinal end is designed to correspond to the first mating face of the current conducting rail and whose second longitudinal end is designed to correspond to the second mating face of the current conducting rail. In the assembled state, the electrical connector is designed to electrically conductively connect one line wire, which is arranged in the current-conducting rail of the first lamp assembly, to one line wire, which is arranged in the current-conducting rail of the second lamp assembly. The electrical connector is particularly preferably held in a detachably fixed manner on the coupling. Particularly preferred is an operating state of the system that can be realized in which the electrical connector connects the wires of the power supply rail of the two lamp assemblies, as explained, with the electrical connector and the coupling on the power supply rail or the support rail of one of the lamp assemblies are ruled out, after which this lamp assembly is then moved longitudinally towards the other lamp assembly, while the coupling is inserted into one of the longitudinal ends of the other lamp assembly and bringing the electrical connector into electrically conductive contact with the lead wires of the other lamp assembly. Preferably, the support rails of the light assemblies are fixed in position by means of the coupling and the electrical connection of the lead wires of the light assemblies is carried out by means of the electrical connector with a single relative movement of the light assemblies to one another that is continuously performed in the longitudinal direction, after one of the light assemblies has previously had the Coupling and the electrical connector have been connected. For the detachable fixing of the electrical connector to the coupling, for example, two latching devices can be provided on the connector and a corresponding latching device on the coupling, with which these are latched to one another. Conductor rail , mounting rail , coupling and connector of the system are designed to correspond to each other in order to be able to realize the corresponding states of the system .

In a particularly preferred embodiment, the conductor rails, support rails, coupling, electrical connector and conductor rail protective caps of the system are designed to correspond to one another in such a way that in the assembled state one of the conductor rail protective caps of the system is optionally on the first longitudinal end of the conductor rail of the first light assembly in the first protective position and on the second longitudinal end of the current conducting rail of the second lamp assembly another current conducting rail protective cap of the system can be arranged in the second protective position with insulation of the conductors arranged in the current conducting rails from one another or alternatively the electrical connector between the current conducting rails of the lamp assemblies with electrically conductive connection of the in the Conductor rails arranged line wires can be arranged i st. It should be taken into account that in the assembled state the first longitudinal end of the current conducting rail of the first lamp assembly points in the longitudinal direction to the second longitudinal end of the current conducting rail of the second lamp assembly and the first longitudinal end of the support rail of the first lamp assembly faces the second longitudinal end of the support rail of the second lamp assembly in the longitudinal direction. Due to the particularly advantageous embodiment of the system according to the invention, a decision can be made during on-site assembly as to whether the conductor rails of interconnected lamp assemblies should be electrically insulated from one another or should be electrically connected to one another. The inventors have recognized that the basic modular concept of the system is particularly advantageous since it enables the protective cap for the conductor rails to be used in a wide variety of positions, thereby enabling the system to be used in a variety of ways in a particularly cost-effective manner. In one embodiment, the system comprises an elongated combination current-conducting rail protective cap, which is designed to correspond at both of its longitudinal ends to one of the two connector faces of the current-conducting rail, as explained here in general for current-conducting rail protective caps and which can have in particular features of embodiments of current-conducting rail protective caps, which are present in connection with a wide variety of Embodiments of the system according to the invention are described. The combination current conducting rail protective cap is elongated in the longitudinal direction in such a way that, in the assembled state, as an alternative to the provision of the electrical connector, it can be arranged with its first longitudinal end on the first longitudinal end of the current conducting rail of the first light assembly and with its second longitudinal end on the second longitudinal end of the current conducting rail of the second light assembly Insulation of the conductor rails arranged in the conductor rails from one another, insulating the conductor wires of the first lamp assembly at its first longitudinal end and the conductor wires of the second lamp assembly at its second longitudinal end, and also ensuring insulation of the conductors of the lamp assemblies from one another. The combination Stromleitbahnenschutzkappe is thus specifically designed so that they are in the assembled state between the Conductor rails of the two lamp assemblies extends that, as generally explained in the present case for conductor rail protective caps, it is arranged with its longitudinal ends at the longitudinal ends of the two conductor rails. In a particularly preferred embodiment, the combination current conductor rail protective cap has a latching device which is designed to correspond to the latching device of the coupling, so that either the electrical connector with its latching device or the combination current conductor rail protective cap with its latching device can be detachably fixed to the coupling.

In one embodiment of the system according to the invention, the coupling has at least one first opening in its coupling base, which is completely closed by a first closure piece which is pressed into a first opening, and the carrier rail has a second opening in its carrier rail base, which in particular is completely is closed by a second closure piece pressed into the second opening. The first closure piece can be released from the first opening by a vertical pressing force. The loosening is preferably possible without deforming the clutch. The second closure piece can preferably be released from the second opening by a vertical pressing force. Detachment is preferably possible without deforming the mounting rail. The respective closure piece is preferably fixed in the respective opening without a material connection, ie without a material connection to the edge defining the opening, preferably exclusively by means of a frictional connection. The embodiment described is generally advantageous for a system for realizing a lamp that is elongated in the longitudinal direction, which comprises at least one support rail that is elongated in the longitudinal direction and a current-conducting rail that is elongated in the longitudinal direction and has channels that run in the longitudinal direction, in each of which at least one conductor wire is arranged, wherein the support rail has a support rail base and two support rail side walls extending away from the support rail base in a vertical direction and spaced apart from one another in a transverse direction by the support rail base, the support rail base and the support rail side walls form a wall which delimits a receiving space open at both longitudinal ends of the support rail for receiving the current conducting rail, the current conducting rail being arranged in the receiving space and fastened to the support rail when the system is in an assembled state. The system can have additional features that are described here in connection with other embodiments. The special configuration of the coupling is particularly preferably used in further embodiments according to the invention, in which, as explained, at least one mounting rail protective cap and/or at least one current conducting rail protective cap is provided and the mounting rail has a corresponding advantageous second holding contour at its longitudinal ends corresponding to the first holding contour of the mounting rail protective cap. The advantageous embodiment described has the particular advantage that the coupling can be designed to be as sealed as possible at its coupling base and, at the same time, the fact that the first closure piece can be pressed out of the first opening makes it easy to feed access lines, for example, into the receiving space of a mounting rail or into the is made possible by two supporting rails connected to the coupling. It is generally preferred that the support rail is made from sheet metal by forming and the coupling is made from another sheet of metal by forming, with the other sheet being harder and/or thicker than the sheet. In this case, the thickness is based on the sheet metal thickness, which in the case of the mounting rail accordingly defines the wall thickness of the mounting rail. The sheet metal from which the mounting rail is made preferably has a sheet metal thickness of at least 0.5 mm, in particular at least 0.6 mm, preferably at most 0.8 mm. The sheet metal from which the clutch is made preferably has a sheet metal thickness of at least 0.9 mm, in particular at least 1.0 mm, in particular at least 1.2 mm. The coupling is particularly preferably made of stainless steel. The coupling is particularly preferably made of sheet metal by means of cutting, in particular stamping, and forming, with the first closure piece being made of sheet metal. The is particularly preferred Mounting rail made from another sheet metal by cutting, in particular punching, and forming, wherein the first closure piece is made from the other sheet metal. The production of the coupling and support rail from one piece of sheet metal enables a particularly simple implementation. The inventors have found that the realization of the opening and the closure piece from a single metal sheet, by means of which the coupling or support rail is produced, can be realized particularly advantageously, inexpensively and with a high cycle rate. The inventors have surprisingly found that the provision of an opening and a closure piece in the coupling is also possible, although the coupling must have sheet metal with sufficient hardness and sheet metal thickness. It has been found to be particularly advantageous to produce the coupling in a manufacturing process during which a metal sheet is cut and unshaped, with the opening being punched in the coupling base by means of a punching tool in an intermediate step of the manufacturing process, with the locking piece being punched out during the realization of the opening, with in a subsequent intermediate step, the closure piece is pressed back into the opening. Particularly preferably, the punching is performed circumferentially closed around the closure piece, so that the closure piece, concerning the coupling of course the first closure piece, is punched out of the sheet metal around its entire circumference and is then pressed back into the opening. Of course, an analogous manufacturing method can be used to implement the mounting rail and the second opening or the second closure piece. The first and the second opening are particularly preferred in the above-mentioned assembled state of the system, in which particularly preferably mounting rail protective caps or current conducting rail protective caps can also be provided on the longitudinal ends of mounting rails and current conducting rails, but do not necessarily have to be provided, in the longitudinal direction between the current conducting rails of the two Lamp assemblies arranged. As a result, the receiving space formed jointly by the connected support rails can be particularly easily accessible be made possible because the conductor rails are arranged offset to the openings and thus an element can be easily guided from the outside into the receiving space through the openings, for example an electrical supply line. In one embodiment, the first opening is aligned with the second opening, so that both openings each form a clear cross-section and these clear cross-sections are aligned with one another, so that an access line can be routed from the outside into the receiving space through these aligned clear cross-sections. Particularly preferably, the system can be used to implement a first operating state in which the first opening is closed by the closure piece, with the coupling connecting the support rails to one another in such a way that the transition between the support rails is dust-tight due to their contact with the coupling, at least according to the standard IP50, preferably according to IP 54. Furthermore, a second operating state can preferably be implemented, in which the first closure piece is removed from the first opening and the first opening is freely accessible from the outside through the second opening, with a prior to the second opening being preferred provided second closure piece is removed from the second opening. In this embodiment, the connection between the support rails is not dust-tight, since the first and second openings allow the receiving space formed by the support rails to be accessed from the outside. When inserting an access line into the receiving space, a sealing means, for example an elastomer plug, is to be provided in the first and/or second opening in order to implement a rod-tightly sealed luminaire. In general, the mounting rails of the lamp assemblies in the assembled state are in contact with their longitudinal ends pointing towards one another, thereby ensuring a dust-tight transition between them. The abutment can be provided directly at their longitudinal ends or indirectly via the coupling, with the dust-tight transition being able to be dust-tight in accordance with the IP50 standard, for example.

In one embodiment, the coupling is in a fixed state of the system, in which a first and a second support rail of the Systems are fixed to one another by the coupling explained here, with a first longitudinal section forming a first longitudinal end of the coupling in the first mounting rail and with a second longitudinal section forming a second longitudinal end of the coupling in the second mounting rail and fixing these two mounting rails to one another. In a separated state of the system, however, the coupling is only arranged with its second longitudinal section in the second mounting rail and is fixed to it and released from the first mounting rail. Thus, in the separated state of the system, the coupling protrudes with its first longitudinal section in the longitudinal direction over the second mounting rail, on which it is fixed in a fixed position. The state of separation and the state of fixation each define a specific arrangement of the components of the system in relation to one another. In the separating state, the first mounting rail is detached from the second mounting rail and the coupling. separated from these and can thus be arranged independently of the second mounting rail and the coupling in the room. First support rail and second support rail are two of the support rails of the system, which are designed to assume the presently defined arrangements in which the presently defined properties of fixation state or. state of separation of the system. The first and second support rails can have features that are generally described herein in connection with a support rail of the system. In the separating state of the system, for example, the second support rail can be a last support rail in the longitudinal direction of a lighting component arrangement or Support rail arrangement in which a plurality of support rails are arranged one behind the other in the longitudinal direction and are held fixed in position to one another via a coupling of the system. In this case, the described coupling, to which the definition of the operating and separating state refers, protrudes beyond one longitudinal end of the second mounting rail, while another mounting rail is arranged at the opposite longitudinal end of the second mounting rail and with a further one Coupling of the system connected to the second mounting rail i st. In this case, as explained above, it may be necessary on a construction site for implementation a sensible termination of the mounting rail arrangement or

Lighting component assembly to separate the coupling from the second support rail and then example swei se the support rail with a support rail end cap ießen complete. In one embodiment, the current conduction rail protective cap is designed as a dismantling tool of the system for releasing the coupling from the second mounting rail, starting from the separating state, so that the current conduction rail protective cap combines several functions, depending on how it is positioned or positioned. is used . The conductor rail protective cap is therefore preferably the dismantling tool explained in more detail below. The coupling has a receptacle that corresponds to the dismantling tool and is formed by at least one of the coupling side walls, in particular by both coupling side walls, and/or the coupling base. The dismantling tool is designed to correspond to the coupling in such a way that it can be inserted into the receptacle to realize a dismantling position of the dismantling tool in such a way that it is guided relative to the coupling with a form fit acting along the longitudinal direction towards the first longitudinal end of the coupling to enable such a force loading on the dismantling tool relative to the second mounting rail in the longitudinal direction towards the first longitudinal end of the coupling, with which the coupling can be detached and removed from the second mounting rail along the longitudinal direction starting from the separating state. The system thus includes a dismantling tool, which is designed specifically to correspond to the coupling, so that the dismantling tool can be used to easily loosen and remove it and thus separate the coupling from the second mounting rail, starting from the separating state in which the coupling with its second longitudinal section in the second support rail is arranged and protrudes with its first longitudinal section over the second support rail in the longitudinal direction. I refer to the separation or Removal of the coupling upon removal of the coupling starting from the longitudinal end of the second mounting rail and away from this longitudinal end of the second mounting rail, which is formed by the longitudinal section of the second mounting rail, in which the coupling with its second longitudinal section im Fixing state and arranged in the separating state i st.

The dismantling tool is thus designed to correspond to the coupling in such a way that the coupling can be released from the second mounting rail by applying a releasing force to the dismantling tool, which acts predominantly in the longitudinal direction, in particular exclusively exclusively in the longitudinal direction, relative to the second mounting rail. In one embodiment, the receptacle and dismantling tool are designed to correspond to one another in such a way that the dismantling tool alone can be used to apply a sufficient release force to the coupling relative to the second mounting rail in order to release the coupling from the second mounting rail, starting from the separating state, and thus from this refer to . It is therefore preferably sufficient to apply force to the coupling by means of the dismantling tool in order to detach it from the second mounting rail.

In one embodiment, the receptacle extends over a transverse width that is at least 10%, in particular at least 20% of a transverse width of the coupling, in particular at least 80%, in particular at least 90% of the transverse width of the coupling. The transverse width of the coupling is the total length of the coupling in the transverse direction. The recording may be uninterrupted or intermittent across its transverse width. For example, the recording can include several partial recordings that are designed together to correspond to the dismantling tool. By providing a correspondingly large transversal width of the receptacle, it can be avoided in a particularly effective manner that the application of the explained releasing force to the dismantling tool and thus to the receptacle of the coupling for separating the coupling from the second mounting rail causes the coupling to jam relative to the second Mounting rail is generated. For example, the recording as two part recordings can have two mutually aligned cutouts, with the disassembly tool cutting into both cutouts or Partial recordings can be introduced. In one embodiment, the receptacle has a contact surface against which the dismantling tool rests in the dismantling position with its longitudinal end pointing toward the first longitudinal end of the coupling. The contact surface runs with at least one directional component perpendicular to the longitudinal direction, so that the force required to pull the coupling out of the second mounting rail can be applied via the contact surface to the coupling via the interaction between the contact surface and the dismantling tool by means of the dismantling tool. In the disassembly position, the disassembly tool preferably lies with its longitudinal end only against the contact surface, so that force is only applied from the disassembly tool to the coupling via the contact surface when the coupling is removed from the second mounting rail by means of the disassembly tool. The receptacle is generally preferably formed by an undercut formed in at least one of the side walls of the clutch and/or the clutch base. This undercut preferably forms the contact surface. The contact surface naturally extends as a surface in two surface directions or Directions in space, with their shape being defined by their two surface directions that span the surface. The surface directions can also be curved, for example when the contact surface has a curved surface profile. At least one of its surface directions, in particular both surface directions within the same surface section, run with a directional component perpendicular to the longitudinal direction. One of the surface directions preferably runs at least in sections perpendicularly to the longitudinal direction. Since the contact surface runs with at least one of its surface directions, in particular with its two surface directions, at least in sections perpendicular to the longitudinal direction, the disassembly tool can be prevented from sliding off its disassembly position when a releasing force is applied to the disassembly tool, with which it is pressed against the contact surface in the longitudinal direction. lean forward very well while it is in its disassembly position. By both surface directions within a surface section of the contact surface perpendicular to the longitudinal direction run, this surface section runs perpendicular to the longitudinal direction. The contact surface preferably has a surface area of at least 2 mm ² , in particular at least 3 mm ² , in particular at least 5 mm ² , in particular less than 50 mm, in particular less than 30 mm ² , over which the dismantling tool can rest on it in the dismantling position abuts, whereby a sufficiently large surface area is provided over which force can be transmitted from the dismantling tool longitudinally to the first longitudinal end of the coupling towards the coupling. The contact surface preferably extends continuously over this surface area with at least one directional component perpendicular to the longitudinal direction. The contact surface can be formed, for example, by a step that runs in a plane perpendicular to the longitudinal direction with a step surface that corresponds to the contact surface. The contact surface can, for example, have an arcuate cross-section running perpendicular to the transverse direction and can extend with a directional component, in particular one of its surface directions, parallel to the transverse direction, with a directional component extending perpendicular to the longitudinal direction due to the extension in the transverse direction. In general, the receptacle preferably encloses the dismantling tool in the dismantling position along at least one specific spatial direction on both of its sides. The receptacle thus preferably extends on both sides, each of which forms an end of the dismantling tool in a specific spatial direction. The specific spatial direction particularly preferably runs perpendicularly to the longitudinal direction. In the dismantling position of the dismantling tool, the receptacle is particularly preferably arranged on one side of the dismantling tool that delimits the dismantling tool in the longitudinal direction towards the first longitudinal end of the coupling, and is arranged on two sides of the dismantling tool that delimits the dismantling tool in a direction perpendicular to the longitudinal direction, in particular limited in the vertical direction. As a result, the receptacle can provide particularly good guidance of the removal tool in the removal position. By recording on one side of the dismantling tool is present, the If the dismantling tool is limited in the longitudinal direction, the dismantling tool can be pressed against the receptacle by applying a releasing force acting in the longitudinal direction, so that the coupling can be released from the second support rail starting from the explained separation state using the dismantling tool. The dismantling tool and contact surface are preferably designed to correspond to one another in such a way that simply by contacting the dismantling tool, a force of at least 50 N acting in the longitudinal direction on the first longitudinal end of the coupling can be transmitted from the dismantling tool to the coupling in order to remove the coupling from the second mounting rail .

In one embodiment, a contour formed in at least one of the side walls of the clutch and/or the clutch base forms at least a section of the receptacle, in particular the receptacle. The contour particularly preferably includes a hole. It is generally preferred that the side walls of the clutch and the base of the clutch are produced in one piece from sheet metal by forming the sheet metal. The contour preferably includes a hole which is provided in the metal sheet. The receptacle preferably includes this hole, so that the hole is part of the receptacle. In one embodiment, the contour comprises a first sub-contour, in particular a first hole, which is provided in a first of the clutch side walls, and a second sub-contour, in particular a second hole, which is provided in a second of the clutch side walls. Particularly preferably, the partial contours each form a part of the receptacle and thus a partial receptacle. The receptacle preferably includes the two partial contours. The partial contours preferably each form a section of the contact surface. By providing a partial contour in each of the coupling side walls, a particularly uniform force can be applied to the coupling relative to the second mounting rail via the disassembly tool, which is held by the receptacle in the disassembling position and rests against both partial contours, thereby preventing the Coupling can be particularly effectively prevented relative to the second mounting rail. Through the design of the partial contours in each case as a hole in the respective clutch side wall, the dismantling tool can be guided particularly well relative to the clutch side walls in its dismantling position and, moreover, the recording can be realized particularly easily in the clutch. The partial contours are particularly preferably arranged in alignment with one another along the transverse direction. This can particularly simplify the insertion of the dismantling tool into the receptacle formed at least in sections by the two partial contours, and this can enable the dismantling tool to apply force evenly to the coupling for releasing the coupling from the second mounting rail.

In one embodiment, the clutch comprises at least one scratch spring that can be resiliently deflected from a rest position on at least one of its clutch side walls and/or on the clutch base. On each of its side walls, the clutch preferably comprises at least one scratch spring that can be resiliently deflected from a rest position. If only one scratch spring is provided, this is preferably arranged centrally on the clutch base with respect to the transverse direction. In one embodiment, at least one scratch spring is arranged on each of the side walls of the clutch, but not on the floor of the clutch. By arranging only one scratch spring in the middle of the coupling base and/or by arranging at least one scratch spring on each of the side walls of the coupling, a uniform fixing of the coupling on the second support rail can be ensured. All scratch springs, i.e. the at least one scratch spring and, if several scratch springs are provided, the scratch springs, are deflected in the separating state with a deflection and each lie against one of the support rail side walls assigned to them and/or the support rail bottom of the second support rail, ensuring that the Coupling relative to the second mounting rail. A rest position of the scratch spring means a position in which no external forces act on the scratch spring encompassed by the clutch. Generally preferred is a first scratch spring on a first of the clutch side walls and a second scratch spring on a second of the clutch side walls arranged, in particular each arranged directly adjacent to this. In the separating state, the scraper spring is deflected in relation to its rest position by the respective support rail side wall against which the respective scraper spring rests and/or by the support rail base against which the respective scraper spring rests, with the formation of an inherent spring force which presses the scratch spring against and thus against the mounting rail presses. Due to the deflection, the scratch spring preferably rests against the supporting rail side walls or the supporting rail base assigned to it with a pressing force that runs at least predominantly perpendicular to the longitudinal direction. In the fixed state, the scratch springs, which are provided on the respective coupling side wall, preferably rest with a scratch spring section on one of the carrier rail side walls and/or the carrier rail bottom of the second carrier rail assigned to them and on one of the carrier rail side walls and/or the carrier rail bottom of the first carrier rail assigned to them Mounting rail so that they are pressed against both the first and the second mounting rail and thereby ensure a fixation of the two mounting rails to each other in the fixed state. In general, the scratch spring is preferably deflected in the de-separating state and in the fixing state in a direction that runs perpendicular to the longitudinal direction, starting from the rest position.

Particularly preferably, the first and second mounting rails each comprise a first and a second mounting rail side wall, and the coupling includes a first scratch spring which, in the fixing state, rests against the two first mounting rail side walls of the two mounting rails, and in particular a second scratch spring, which, in the fixing state, rests against the second Support rail side walls of the two support rails in a fixed position. As a result, the relative position of the two support rails to one another can be particularly favored due to the contact of the scratch spring on the support rail side walls of both support rails. Generally preferably, each of the clutch sidewalls includes a clutch sidewall portion. The coupling side wall section preferably extends in a straight line along the vertical direction and rests on the first and second mounting rails at its vertical upper end and at its vertical lower end. Due to the rectilinear extension of the coupling side wall section and the contact with its vertical ends, the coupling side wall section enables a particularly reliable fixing of the coupling to the mounting rails and thus a particularly reliable fixing of the mounting rails to one another.

The at least one scratch spring ensures that the coupling is fixed particularly reliably on the support rails. In particular, the at least one scratch spring ensures reliable relative fixing of the support rails to one another in the longitudinal direction in the fixing state, in that the scratch spring digs into the support rails. In addition, the scratch spring can produce a reliable electrical contact between the two mounting rails, so that when only one mounting rail is connected to a PE conductor via the coupling, the other of the mounting rails is also connected to the PE conductor. If the scratch spring is arranged on the side wall of the clutch, the scratch spring can also be provided in a particularly space-saving manner.

All scratch springs are particularly preferably arranged exclusively in a longitudinal area of the coupling which, in the fixed state, extends in the longitudinal direction by less than 10 cm, in particular less than 8 cm, in particular less than 5 cm, in particular less than 3 cm, extending into both support rails. By the scratch spring is thus provided near the mutually facing longitudinal ends of the support rail, the assembly of the support rails is particularly simplified, since the force generated by the scratch spring on the support rail side wall only has to be overcome over a short joining distance. In a In a preferred embodiment, the scratch springs each have at least one scratch nose which, in the separating state, presses directly against one of the support rail side walls and/or the support rail bottom of the second support rail. In particular, the scratch springs each have a plurality of scratch lugs, which are spaced apart from one another in particular in the longitudinal direction and in particular along the transverse direction, with all of the scratch lugs particularly preferably in the fixed state directly against one of the support rail side walls and/or one of the support rail bottoms of the first and second support rail press. In particular, the scratch springs have a spring section, in particular several spring sections. The spring section, in particular the spring sections, extend away from at least one, in particular all of the scratching lugs, in particular in the longitudinal direction and preferably in a direction perpendicular to the longitudinal direction of the scratching lug. In particular, the spring section is directly adjacent to the scratching nose. The spring section preferably forms a first section of the scratch spring and the scratching nose forms a second section, with the two sections merging into one another by bending, in particular at an angle of at least 30°, with the first section forming an angle to the transverse direction that is at least 30° greater than the second section. In the operating position, the spring section, in particular each of the spring sections, is resiliently deflected in relation to the rest position along a deflection direction that runs perpendicularly to the longitudinal direction. In particular, the scratching nose is rigid in a section extending away from the spring section along the deflection direction. Preferably, in the separating state and in particular in the fixing state, at least 90% of the deflection of the scratch spring, starting from the rest position, is realized by deflection of the spring section and thus not by the scratch nose. In particular, a projection surface that depicts the extent of the spring section and runs perpendicular to the direction of deflection is larger, in particular 20% larger, in particular 60% larger, in particular 80% larger, in particular more than 100% larger than a projection surface that depicts the extent of the scratching nose and Projection surface running perpendicular to the deflection direction. In particular, the scratching nose has an axial moment of inertia that is at least twice as high as the axial moment of inertia of the spring section based on a deformation caused by the deflection in the deflection direction. In a preferred embodiment, the scratch springs are formed separately from the first and second clutch side walls. In particular, the scratch lugs are each attached to one of the side walls of the clutch, in particular indirectly via the spring section of the respective scratch spring. The scraper springs are particularly preferably deflected in the separating state and in particular in the fixing state, starting from their rest position in the vertical direction. In this way, a sufficient spring pressure force can be ensured in a particularly effective manner, with which the scraper springs press in the vertical direction against the side wall of the mounting rail or the base of the mounting rail.

In one embodiment, the conductor rail protective cap is designed as a release tool of the system, which is designed to correspond to the scratch springs and in a release position in which it can be used on all scratch springs, ie if only one scratch spring is provided on one scratch spring, if several are provided Scratch springs on all scratch springs, rests and deflects them beyond the deflection, can be arranged under realization of a release state of the system starting from the separating state in which all scratch springs are released from the second mounting rail. The conductor rail protective cap thus combines several functions, depending on how it is positioned or used. Thus, the conductor rail protective cap is preferably the release tool of the system, which is explained in more detail below. In the released state, the coupling is arranged with its second longitudinal section in the second support rail, unchanged compared to the separated state. However, while in the separating state the scraper springs press against the support rail side walls of the second support rail assigned to them and/or against the support rail bottom of the second support rail, the scratch springs are in the state of being released from them j ewei ls associated mounting rail side wall or. the support rail base of the second support rail is released, so that in the released state the scratch springs no longer contribute to fixing the coupling relative to the second support rail. The release tool can thus be used to achieve such a deflection of the scratch springs, starting from which the coupling can be removed particularly easily from the second support rail, in particular by a displacement movement of the coupling as explained in the longitudinal direction. Thus, starting from the separating state, the coupling can be separated from the second mounting rail in that the release state is first reached by means of the release tool, in that the release tool is positioned in its release position, after which the coupling side walls and the coupling base relative to the second mounting rail in the longitudinal direction be moved to remove the coupling from the second mounting rail. The release tool is thus designed to correspond to the scratch springs that are provided on the two side walls of the clutch. The scratch springs can thus be released by the release tool, so that the one release tool makes it particularly easy to separate the coupling from the second support rail. The detachment of the scratch springs from the second support rail particularly preferably reduces the amount of force acting in the longitudinal direction required to remove the coupling from the support rail by at least 50%, in particular by at least 70%. For example, the second mounting rail and the coupling can be designed to correspond to one another in such a way that, in order to remove the coupling from the second mounting rail, starting from the separating state while avoiding reaching the release state, ie. H . if, starting from the assembled state, the coupling is removed from the second mounting rail without the scratch springs being detached from the second mounting rail while they are inside the second mounting rail, a longitudinal force of at least 200 N, in particular at least 300 N is required, while for removing the coupling from the second support rail, starting from the separating state after reaching the release state and maintaining the release state achieved in the release of the Scratch springs from the second mounting rail only a force acting in the longitudinal direction of less than 100 N, in particular less than 80 N, in particular less than 60 N is required. In the separating state, at least one of the scratch springs is particularly preferably in contact with one of the carrier rail side walls of the second carrier rail and the release tool is in the release state in contact with all the scratch springs, spanning the coupling base. Thus, the scratch springs, which are arranged on the two side walls of the clutch, can be released in a particularly simple manner by the one release tool that spans the clutch base in its release position.

In one embodiment, the scraper springs in the separating state each press with a spring force acting in the vertical direction against a projection provided in the supporting rail side walls assigned to them and/or against the supporting rail base. Since the support rail side walls extend over a considerable vertical extent, a particularly effective, sufficiently large pressing force can be provided between scratch spring and support rail side wall by the vertical pressing against such a projection. Particularly preferably, the coupling side walls rest with an upper and a lower end of a coupling side wall section formed by them on a respective guide receptacle assigned to them, which is formed by the supporting rail side walls assigned to them and in particular together with the supporting rail base, the coupling side wall section comprising a flat wall area, which is perpendicular to the transverse direction and connects the upper and lower ends of the coupling side wall portion to each other. As a result, the clutch side wall section can be designed to be particularly resilient in the vertical direction. As a result, a scratch spring can be fixed to the clutch side wall section, in particular surrounded by the wall region, so that it can be subjected to particularly high loads in the vertical direction. Particularly preferably, the clutch side walls each have a step with a recess through which the scratch springs each extend in the vertical direction extend through. The coupling side wall section, which is accommodated by the guide receptacle of the second support rail in the separating state and rests against this guide receptacle with its upper and lower end, preferably extends in the vertical direction beyond this recess. The formation of a shoulder can particularly advantageously ensure that the scratch spring passes through the clutch side wall without mechanical impairment of the stability of the clutch side wall section. The respective scratch spring is generally preferably arranged and fastened on an inner side of the clutch side wall assigned to it or on the inner side of the clutch base, the inner side of the clutch side wall obviously being the side of the clutch side wall which faces the other clutch side wall in the transverse direction.

In one embodiment, at least one of the coupling side walls and/or the coupling base includes a fixing device and the scratch spring arranged on the respective coupling side wall or the coupling base includes a holding device designed to correspond to the fixing device. In particular, the fixing device is integrally formed by the clutch side wall or by the clutch base and/or the holding device by the scratch spring. In particular, the first clutch side wall and the second clutch side wall each have a fixing device, with the scratch springs each having a holding device designed to correspond to the fixing device of the clutch side wall assigned to them. In the separating state and in particular in the fixing state, the fixing device is connected to the holding device in particular rigidly, in particular positively and/or non-positively, with the scratch spring being fixed in position on the clutch side wall. In particular, the fixing device is positively connected to the holding device along the longitudinal direction. In particular, in the separating state and in particular in the fixing state, the fixing device with the Retaining device based on a direction perpendicular to the longitudinal direction connected exclusively non-positively. In particular, the fixing device and the holding device are clamped to one another with the scratch spring being fixed in position on the clutch side wall. In particular, the fixing device and the holding device can be connected to one another by applying a fixing force directed perpendicular to the longitudinal direction.

In one embodiment, the release tool and the dismantling tool are both integrated in the current-conducting rail protective cap, so that the current-conducting rail protective cap is a multifunctional tool of the system. Particularly preferably, the tool can be brought into the dismantling position in such a way that it simultaneously holds the dismantling position and the release position, so that the system is in the released state when the tool is in the disassembly position. With this tool, the scratch springs can be released at the same time and the tool can be arranged in the receptacle in such a way that a force can be applied in the longitudinal direction to the coupling relative to the second mounting rail, with which the coupling can be pulled out of the mounting rail while the scratch springs are deflected so far that they no longer contribute to fixing the clutch relative to the second mounting rail.

In one embodiment, the current-conducting rail protective cap has a cap body in which channels are formed for receiving end sections of the conductors of the second current-conducting rail. The end sections of the line wires form the respective end of the line wire at the longitudinal end of the current conducting rail, onto which the current conducting rail protective cap is placed in its protective position. A wing is formed at each transverse end of the cap body, the wings forming a portion of the dismantling tool that interacts with the receptacle and/or a portion of the release tool that interacts with the scratching springs. By having a cap body with channels for accommodating end portions of the conductor rails of the second conductor rail, the conductor rail protective cap can effectively provide insulation of the conductor wires at said end of the second conductor rail. The inventors have recognized that it is particularly advantageous to provide at least one wing on this cap body, which can be specifically designed to ensure adequate insulation, which can then provide further properties of the current-carrying rail protective cap as a disassembly or release tool and for this purpose without Consideration can be given to the properties of the conductor rail protective cap that are required to achieve adequate insulation, since these are already provided by the design of the cap body that is tailored to this. Particularly preferably, the wing, all of the wings when a plurality of wings are provided, is provided at one end, ie one side of the cap body, which delimits the cap body in a direction perpendicular to the longitudinal direction. Specifically, a wing is provided at each transverse end of the cap body. It is generally preferred that all wings and the cap body are manufactured as a one-piece component, in particular by means of an injection molding process.

All wings are particularly preferably arranged at least in sections outside the spatial extent of the cap body, both with respect to the transverse direction and with respect to the vertical direction, which is formed or arranged between the wings in the transverse direction. In one embodiment, the at least one wing, in particular each of the plurality of wings, has a first and a second wing part. In one embodiment, the first wing portion is configured to interact with the receptacle and the second wing portion is configured to interact with the scratch springs. In one embodiment, the first wing portion is angled toward the second wing portion. In one embodiment, the second wing part is at least as large as the first wing part, in particular larger, in particular at least 1.5 times as large as the first wing part body volume is turned off. As a result, the different requirements placed on the two wing parts can be taken into account particularly well and at the same time the size of the wing can be kept as small as possible. In general, it should be noted that the interaction of the wings with the scratch springs can provide the explained further deflection of the scratch springs in order to implement the release state in which the scratch springs are released from the second mounting rail and the coupling can therefore be removed particularly easily from the second mounting rail can. Furthermore, it should be pointed out in general that the interaction of the wings with the receptacle is aimed at the fact that, as explained, by means of the current conduction rail protective cap acting as a dismantling tool, in the dismantling position of the current conduction rail protective cap, such a force can be applied to the coupling by means of the current conduction rail protective cap that, starting from the separation state , can be moved out of the second mounting rail, in particular under previously implemented realization of the release state.

The invention also relates to a lamp that is produced by means of a system according to the invention. The system is in one of the operating states explained above. The luminaire particularly preferably comprises at least one mounting body, with the mounting body closing the opening of the at least one mounting rail of the lamp facing away from the base of the mounting rail, in particular closing it in a dust-tight manner, with the mounting body being in particular designed in several parts and having a sheet metal body and a cover which together can be used for closing of the opening are fixed to the mounting rail.

The invention also relates to a conductor rail protective cap that is designed to correspond to an embodiment of a system according to the invention. The Stromleitbahnen protective cap is designed to correspond to an embodiment of the system, in which the arranged in the channels of the Stromleitschiene line wires from both longitudinal ends of the current conducting rail are accessible and the current conducting rail forms a first plug face at its first longitudinal end and a second plug face that differs from the first plug face at its second longitudinal end, wherein the current conducting rail protective cap has two longitudinal ends that are designed differently and of which a first longitudinal end is the first Plug face and a second longitudinal end are designed to correspond to the second plug face in such a way that the conductor rail protective cap can be plugged with its first longitudinal end to insulate the conductors at the first longitudinal end of the conductor rail on the first longitudinal end of the conductor rail in a first protective position and with its second longitudinal end to insulate the conductors at the second longitudinal end of the current conducting rail can be plugged onto the second longitudinal end of the current conducting rail in a second protective position.

The invention also relates to a mounting rail protective cap for an embodiment of a system according to the invention. In the embodiment of the system according to the invention, each longitudinal end of the support rail is formed by a respective longitudinal end region of the support rail, which has a second holding contour. The mounting rail protective cap has a first retaining contour, each of the retaining contours having a gripping section and a pressing section spaced from this in a blocking direction running perpendicular to the longitudinal direction, wherein the mounting rail protective cap can be fastened in an operating position to the longitudinal end section forming this longitudinal end in order to close a specific one of the longitudinal ends with the holding contours being brought into engagement in such a way that the holding contours press against one another with their pressing sections along the blocking direction and that the gripping section of the mounting rail protective cap is spaced further from the longitudinal end of the mounting rail in the longitudinal direction than the gripping section of the mounting rail and overlaps with it in the blocking direction.

The invention also relates to a support rail for an embodiment of a system according to the invention. The support rail is elongated in the longitudinal direction and has a support rail bottom and two support rail side walls extending away from the support rail bottom in a vertical direction and spaced apart from one another in a transverse direction by and connected by the support rail bottom. The base of the mounting rail and the side walls of the mounting rail form a wall which delimits a receiving space open at both longitudinal ends of the mounting rail for receiving the current conducting rail. An embossing is formed on an inside of the wall facing the receiving space, in particular in the base of the mounting rail. The embossing is preferably designed as explained above, in particular as a gripping section of the mounting rail, which is designed to correspond to a gripping section of a mounting rail protective cap of the system, as explained above. In one embodiment, the support rail side walls each have a projection facing the other support rail side wall within their vertical end region facing away from the support rail base. In one embodiment, the support rail side walls each have a contour with a constriction within their vertical end region adjoining the support rail base. The vertical end regions preferably each extend from an absolute vertical end of the mounting rail over at most 30%, in particular at most 20% of the total vertical extent of the mounting rail between its absolute vertical ends. The projection and the constriction can each be realized by reshaping the respective support rail side wall. The contour or constriction forms a recess on the outside of the respective mounting rail side wall and a projection resulting from the recess on the inside of the respective mounting rail side wall, this projection facing or protruding towards the other mounting rail side wall. Particularly preferably, the projection provided in the vertical end region facing away from the base of the mounting rail is formed by reshaping the side wall of the mounting rail at its extension end. Starting from this projection, the support rail side wall preferably extends, in particular over several deformations, up to the base of the carrier rail. The inventors have recognized that a system according to the invention with the advantages described can be implemented particularly advantageously by means of such a mounting rail.

The invention also relates to a clutch for an embodiment of a system according to the invention. The clutch has a clutch floor and clutch sidewalls. The coupling is designed to correspond to each of the mounting rails of the system in such a way that it can be inserted from each longitudinal end of each mounting rail into the mounting rail in the longitudinal direction to implement an assembled state of the system in which the coupling is inserted into the first longitudinal end of the mounting rail of a first lighting assembly is and is inserted into the second longitudinal end of the mounting rail of a second lamp assembly with positionally fixed fixing of the mounting rails of the lamp assemblies to each other. More detailed explanations regarding the state of assembly of the second lamp assemblies have already been made in connection with embodiments of the system according to the invention. The coupling has in its coupling base at least one first opening which is completely closed by a first plug pressed into the first opening, the first plug being detachable from the first opening by a vertical pressing force.

The invention also relates to a method for realizing a lamp using a system according to the invention. In one embodiment of the method according to the invention, starting from the assembly state, an identically designed conductor rail protective cap is pushed in the longitudinal direction onto both longitudinal ends of the conductor rail and an identically designed carrier rail protective cap is pushed onto both longitudinal ends of the carrier rail, with the conductor rail protective caps being fixed in position on the conductor rail and the carrier rail protective caps on the carrier rail . In one embodiment of the method according to the invention, a first and a second lamp assembly, which each comprise a support rail and a current-conducting rail attached thereto, connected to one another by a coupling being fixed to one longitudinal end of the first light assembly and an electrical connector or a first current-conducting rail protective cap being connected to the longitudinal end of the current-conducting rail of the first light assembly lying at this longitudinal end of the first light assembly , and by pushing the first lighting assembly with the coupling fixed to its mounting rail in the longitudinal direction towards the second lighting assembly, inserting the coupling into the mounting rail of the second lighting assembly and fixing the coupling to this mounting rail of the second lighting assembly and by during the insertion of the coupling into the The mounting rail of the second light assembly is connected to the electrical connector at the longitudinal end of the current conduction rail of the second light assembly pointing to the current conduction rail of the first light assembly, or by connecting a second current conduction rail protective cap to the longitudinal end of the current conduction rail of the second light assembly pointing to the current conduction rail of the first light assembly.

In Figure 1, comprising Figures 1a and 1b, a mounting rail 1 and a mounting rail protective cap 2 are shown separately in schematic representations of the principle. FIG. 2, comprising FIGS. 2a and 2b, each shows views of the mounting rail 1 and the mounting rail protective cap 2 in the operating position of the mounting rail protective cap 2. While a sectional view is shown in FIG. 2a, a plan view is shown in FIG. 2b. Figures 1 and 2 are explained together below. It can be seen from the figures that the mounting rail 1 has a mounting rail bottom 11 and two mounting rail side walls 12 . The support rail base 11 extends in the transverse direction Y between the two support rail side walls 12, which extend away from the support rail base 11 in the vertical direction Z and are spaced from the support rail base 11 in the transverse direction Y. Support rail side walls 12 and support rail base 11 are connected to one another in one piece and merge directly into one another, which is generally advantageous according to the invention. In the present case, the mounting rail 1 is made from sheet metal by means of forming. The support rail 1 extends in the longitudinal direction X in an elongated manner. The support rail 1 has a length in the longitudinal direction X that is more than five times, in particular more than ten times, in particular more than twenty times the width of the support rail 1 in the transverse direction Y, which is generally advantageous according to the invention. The mounting rail side walls 12 each have a projection 13 running in the transverse direction Y, which extends as a projection toward the opposite mounting rail side wall 12 . In its mounting rail base 11, the mounting rail 1 has an embossing 14, which in the present case is formed by two partial embossings, which run over a width in the transverse direction Y and are spaced apart from one another in the transverse direction Y. The support rail 1 also has a contour 120 which is formed as a constriction of the support rail side walls 12 what according to the invention is generally advantageous, since this allows the mountability of the mounting rail 1 and the stability of the mounting rail 1 to be realized in a particularly advantageous manner. The support rail protective cap 2 has a plug-in section which, in the operating position shown in FIG. The plug-in section has two side walls 22 and a base 25 connecting the side walls 22, the base 25 connecting the side walls 22 in the transverse direction Y. The side walls 22 each have a projection 23 which protrudes in relation to adjacent areas along the pressing direction, which in the present case corresponds to the vertical direction Z. The projection 23 has an insertion bevel, so that the support rail protective cap 2 can be pushed onto one of the longitudinal ends of the support rail 1 in the longitudinal direction X to achieve the operating position, with increasing pressure being generated during the pushing-on due to the insertion bevel of the projection 23 which the projection 23 of the mounting rail protective cap 2 presses against the projection 13 assigned to it on the mounting rail side wall 12 assigned to its side wall 22 . As can be seen by looking at FIGS. 1 and 2 together, the mounting rail protective cap 2 with its plug-in section has an outer contour which essentially corresponds to the inner contour of the mounting rail 1, which is generally advantageous according to the invention. Thus, the side walls 22 of the support rail protective cap 2 form corresponding constrictions 220 which correspond to the constrictions or the contour 120 of the side walls 12 of the support rail 1 .

Looking at Figures 1 and 2 together, it can be seen in particular that the mounting rail 1 has an embossing 14 in its mounting rail bottom 11, which forms a section that engages behind the mounting rail 1, whereas the mounting rail protective cap 2 has a projection 24 that forms the section that engages behind the mounting rail protective cap 2 forms. The gripping section and thus the projection 24 are formed from the bottom of the plug-in section of the mounting rail protective cap 2, which is generally advantageous according to the invention. Embossing 14 and protrusion 24 include in each case a plurality of partial sections spaced apart from one another in the transverse direction Y, in each case one partial embossing together with a partial projection forming a pair which are in engagement with one another in the operating position shown in FIG. As indicated in FIG. 1b, the embossing 14 has a cross section perpendicular to the transverse direction Y, which is designed in the manner of a triangle, the depth of the embossing 14 decreasing in the longitudinal direction X with increasing distance from the longitudinal end. Correspondingly, a substantially right-angled step is formed between the embossing 14 and the section of the support rail base 11 immediately adjacent in the longitudinal direction X, and in the operating position the projection 24 rests against this step, as shown in Figure 2a, whereby the support rail protective cap 2 with reference to the longitudinal direction X is held in a fixed position on the support rail 1 . Because the projections 23, 13 of the mounting rail protective cap 2 and mounting rail 1 form pressing sections of the mounting rail protective cap 2 and mounting rail 1, which press against one another in the pressing direction, in this case the vertical direction Z, the gripping sections, which are presently formed by the projection 24 and embossing 23, are in one position forced, in which they overlap along the vertical direction Z, whereby the meshing of the engagement sections is secured, even if the embossing 14 has only a small depth. In the present case, the embossing 14 has a depth of 0.4 mm, the wall, and thus also the mounting rail base 11, having a wall thickness of approximately 0.6 mm. The support rail base 11 is smooth on its outside at the level of the embossing 14 . At this point it should be pointed out that the projections 23 are visible in FIG. 2 purely for explanation purposes and are shown as supposedly plunging through the projections 13 of the support rail 1, whereas in reality the projections 23 naturally rest on the projections 13 and press against them . For special securing of the support rail protective cap 2 on the support rail 1, the support rail also has an overlapping section which, starting from the longitudinal end of the support rail 1 in the longitudinal direction towards the embossing 14, almost reaches the area of the embossing 14 on the Outside of the support rail base 1 runs, whereby the support rail protective cap 2 forms a groove into which the support rail base 11 is inserted. The formation of such a groove, in particular, as in the present case, by the base forming the gripping section and the overlapping section of the mounting rail protective cap 2, is generally advantageous according to the invention. The mounting rail protective cap 2 also has a cover section, in which knockout sections 20 are provided, which can be broken out from the rest of the cover section along respective material weakening lines that enclose them and that are provided in the cover section, as a result of which a knockout opening can be realized in each case through which a supply cable can be guided into the receiving space of the support rail 1 from the outside. The cover section ensures a reliable closure of the accommodation space, and the break-out sections 20 allow the insertion of supply lines into the accommodation space.

In FIG. 3, which includes FIGS. 3a and 3b, a conductor rail protective cap 3 is shown in two different views in schematic representations. While FIG. 3a shows an oblique view from a first vertical side, FIG. 3b shows an oblique view from the opposite vertical side. It can be seen from Figure 3 that the current-conducting rail protective cap 3 has a different plug-in face at each of its two longitudinal ends, with which it can be plugged onto one longitudinal end of a current-conducting rail 4, as is shown in Figure 4 including Figures 4a and 4b for a first longitudinal end of the current-conducting rail 4 is shown and FIG. 5 comprising FIGS. 5a and 5b for a second longitudinal end of the current-conducting rail 4 opposite the first. The conductor rail protective cap 3 has a first longitudinal end area forming the first longitudinal end and a second longitudinal end area forming the second longitudinal end. Each of the longitudinal end regions comprises channel sections, the channel sections being aligned with one another and in Longitudinally X between the longitudinal ends of the Stromleitbahnenschutzkappe 3 continuously extending channels 30 form. The channels 30 are formed by channel walls, which form the channels between them, and as can be seen from Figures 4b and 5b in combination with Figures 4a and 4b, the conductor wires 5, which are arranged in the channels 30 of the current conducting rail 4, when plugged on of the current conduction rail protective cap 3 can be arranged on a longitudinal end of the current conduction rail 4 in the channels 30 of the current conduction rail protective cap 3 . Looking at FIGS. 3, 4 and 5 together, it can be seen that the different connector faces of the conductor rail protective cap

3 differ at least in that the arrangement of the channels 30 in the line-up direction, which in the present case corresponds to the transverse direction Y, is different, since the channels 30 are not arranged symmetrically. The designation plug-in face relates to the design of the respective longitudinal end when the longitudinal end is viewed along the longitudinal direction X. Furthermore, the connector faces differ in the configuration of the transversal outer sides of the conductor rail protective cap 3 in their respective longitudinal end regions. The conductor rail protective cap 3 has a grip device 320, 310 at each of its longitudinal ends. The rear grip device 310, 320 is provided on a holding arm 311, 32 in each case. The current-conducting rail protective cap 3 is designed to be slipped onto one of the longitudinal ends of the current-conducting rail 4, as shown in Figure 4, in that its holding arms 311 are arranged on a vertical outer side of the current-conducting rail 4 and their rear-engagement devices 310 engage with corresponding rear-engagement devices of the current-conducting rail 4 be brought, in the present case, the rear grip devices of the current conducting rail 4 are not shown and are designed as recesses into which the rear grip devices 310 engage. As can be seen in FIG. 4, the conductor rail

4 has transversely outer side walls 41 in its longitudinal end section 401, with which it transversely surrounds the protective cap 3 for conductor rails in the protective position shown in FIG. 4b and thus rests transversely from the outside against the transversal end 31 of the current-conducting rail protective cap 3 provided in the first longitudinal end region of the current-conducting rail protective cap 3 . The ends of the line wires 5, with which they protrude beyond the channels of the current-conducting rail 4 at the relevant longitudinal end, as shown in FIG. The channels 40 of the current-conducting rail 4 and the channels 30 of the current-conducting rail protective cap 3 overlap in the longitudinal direction X and together form continuous channels in the longitudinal direction X. At the other longitudinal end of the current conducting rail 4, the current conducting rail protective cap 3 can be plugged with its other longitudinal end, as is shown in FIG. Correspondingly, the current conducting rail 4 has a differently configured longitudinal end region 402 at its other longitudinal end, in which a differently configured rear grip device 42 is provided, which engages with the rear grip device 320 at the corresponding longitudinal end of the current conducting rail protective cap 3, as shown in Figure 5b , when the conductor rail protective cap 3 is arranged in its corresponding protective position. As shown in Figure 3a and generally advantageously, the conductor rail protective cap 3 also has spacer sections 326 on one of its vertical sides, with which it can be arranged supported in any protective position relative to the mounting rail base 11 while ensuring a sufficient distance between the channel bases of its channels 30 and the mounting rail base 11 Correspondingly, it is generally advantageously provided that these section sections 326 are arranged in the operating position on the vertical side of the current-conducting rail 4 facing away from the access side. Accordingly, it is generally preferred that the holding arms 311 and rear grip devices 310, with which the current conducting rail protective cap 3 runs on a vertical outer side of the current conducting rail 4 in the protective position shown in Figure 4, are arranged on the side of the current conducting rail 4 facing away from the access side. In general, the conductor rail protective cap 3 is particularly preferably designed in such a way that in each protective position, its same vertical side faces the same side as the access side of the current-carrying rail 4, as also shown in the present embodiment. As a result, the channels 30 of the current-conducting rail protective cap 3 can be designed particularly well with respect to the channels 40 of the current-conducting rail 4 .

In FIG. 6, comprising FIGS. 6a, 6b and 6c, an embodiment of a system according to the invention is shown in various basic representations in an operating state, different components of the system being shown in each case in the various representations. The exemplary embodiment according to FIG. As shown in FIG. 6a, the support rails 1 of the lamp assemblies are arranged in abutting relationship in the longitudinal direction X when the system is in operation. The support rails 1 are connected to one another in a fixed position by a coupling 8 as shown in FIG. 6b. For this purpose, the coupling 8 is introduced into the respective support rail 1 from the respective longitudinal end. The coupling 8 has a scratch spring with scratch lugs 81 which presses against the side walls of the support rails 1, whereby the relative position of the support rails 1 to one another is fixed particularly reliably, which is generally advantageous according to the invention. As shown in FIG. 6b, the coupling 8 has four first openings in its coupling base, each of which is closed by a first closure piece 800, as shown here. The mounting rails 1 each have two second openings, which in the present case are each closed by a second closure piece 100 . In the state shown in FIG. 6a, the first and second openings are arranged in alignment with one another, although they cannot be seen in FIG. 6a, but can be seen from the combination of FIGS. 6a and 6b. Correspondingly, in the operating state shown, a dust-tight seal of the receiving space formed by the support rails 1 is ensured. On the other hand, for example, a lead can be inserted into this receiving space by a first closure piece 800 and a second closure piece 100 is pressed out of the openings along the vertical direction Z, resulting in a passage through which the supply line can be guided into the receiving space. After the area between the supply line and the edge of the respective opening has been sealed, a dust-tight sealing of the receiving space can then be achieved again. As can be seen in Figure 6c, in the exemplary embodiment described, a current-conducting rail protective cap 3 is arranged on the longitudinal ends of the current-conducting rails 4 of the lamp assemblies that face one another in the longitudinal direction X, with the current-conducting rail protective cap 3 being plugged with a respective other longitudinal end onto the other of the two current-conducting rails 4 and in doing so with its holding devices 310, 320, which are provided at the respective longitudinal end, is held in a fixed position on the current conducting rail 4 and, as shown in FIGS. 4 and 5, the conductor wires 5 arranged in the current conducting rails 4 are electrically insulated from one another at the respective end.

FIG. 7 shows a schematic representation of a conductor rail protective cap 3 and a mounting rail protective cap 2 of a further embodiment of a system according to the invention. The main difference between the embodiment according to Figure 7 and the embodiments according to Figures 1 to 6 is that the mounting rail protective cap 2 can be captively connected to the current conducting rail protective cap 3, for which purpose the mounting rail protective cap 2 has a guide rail 26, on which the current conducting rail protective cap 3 can be attached along the longitudinal direction X can be postponed. Thus, two relative positions of the current conducting rail protective cap 3 relative to the supporting rail protective cap 2 can be realized, wherein in the first relative position the current conducting rail protective cap 3 points with one of its longitudinal ends in the longitudinal direction X to the supporting rail protective cap 2 and with its opposite longitudinal end points away from the supporting rail protective cap 2, whereas in the second relative position it points with its one longitudinal end points away in the longitudinal direction X of the support rail protective cap 2 and with its other longitudinal end to DIN rail protective cap 2 indicates. Accordingly, a coherent component can be created by targeted positioning of the conductor rail protective cap 3 on the mounting rail protective cap 2, which can be plugged onto one end of a lighting assembly, whereby using the same mounting rail protective cap 2 and the same conductor rail protective cap 3 by changing the relative position creates a coherent component can be created that can be plugged onto the other longitudinal end of a lighting assembly, wherein when the entire component is plugged in, which can be plugged together, the receiving space at the respective longitudinal end of the mounting rail 1 can be closed at the same time and the conductor wires 5 at the respective longitudinal end of the conductor rail 4 can be isolated by the conductor rail protective cap 3.

FIG. 8, comprising FIGS. 8a, 8b and 8c, shows the combination current conductor rail protective cap 3 of an embodiment of a system according to the invention. As can be seen from FIG. 8a, this combination conductor rail protective cap 300 is elongated in the longitudinal direction X and forms a first longitudinal end region 301 and a second longitudinal end region 302. With the first longitudinal end area 301 it can be plugged onto a first longitudinal end of a current-conducting rail 4 of the system, with its second longitudinal end area 302 it can be plugged onto a second longitudinal end of the current-conducting rail 4 of the system. Furthermore, the combination conductor rail protective cap 300 has a latching device 303 . The embodiment according to FIG. 8 of the system according to the invention also includes an electrical connector 9. The electrical connector 9 has a latching device which corresponds to the latching device 303 of the combination current-conducting rail protective cap 300. In the system according to the invention, it is provided that either the combination conductor rail protective cap 300 or the electrical connector 900 can be attached to the coupling 8 . Correspondingly, when using a coupling 8 to which an electrical connector 9 according to FIG. 8c is fixed, be mechanically connected to each other by the coupling 8 by means of their support rails 1 and their lead wires 5 be connected to each other by means of the electrical connector 9. On the other hand, when using a coupling 8 with a combination conductor rail protective cap 300 attached to it, as shown in Figure 8b, two lamp assemblies of the system can be connected to one another in a fixed position by means of the coupling 8 by means of their mounting rails 1, while the combination conductor rail protective cap 300 ensures that the conductors 5 at the two ends of the conductor rails 4 of the lamp assemblies, which face one another in the longitudinal direction X, are each reliably isolated.

In FIG. 9, comprising FIGS. 9a and 9b, a conductor rail protective cap 2 of an embodiment of a system according to the invention is shown schematically in two schematic representations with two different views. This current-conducting rail protective cap 3 is made as a plastic injection-moulded part and fulfills several purposes at the same time: On the one hand, the current-conducting rail protective cap 3 can be attached with its cap body 35 to a longitudinal end of the current-conducting rail 4 to insulate the conductor wires 5, which are arranged in the current-conducting rail 4, as is rudimentarily shown in Figure 9a is shown. For this purpose, the conductor rail protective cap 3 has channels 30 in its cap body 35 for receiving end sections of the conductor wires 5, as is shown in FIG. 9b. A wing 33 is formed at each transverse end of the cap body 35, respectively. With these wings 33, the conductor rail protective cap 3 fulfills another purpose, namely its suitability as a disassembly and release tool. The wings 33 each have a first wing part 332, which is designed to interact with the receptacle 860, which is shown by way of example in FIG. In addition, the wings have a second wing part 331, which is designed to interact with the scratch springs 88 so that the conductor rail protective cap 3 can fulfill its purpose as a release tool. first and second Wing part 332, 331 are angled to each other, in this case by approx. 90° angled to each other. The mode of operation of the conductor rail protective cap 3 as a release tool, ie its interaction with the scratch springs 88, and the mode of operation of the scratch springs 88 per se can be seen in particular from FIG. 10 including FIGS. 10a, 10b, 10c, 10d and 10e. The scratch springs 88 each have a holding device 83 which is designed to correspond to a fixing device 84 which is designed on the respective clutch side wall, as can be seen in particular from FIGS. 10a, 10b and 10c. The scratch springs 88 also each have a spring section 82 which is designed to be resilient in the vertical direction Z and via which the scratch noses 81 of the scratch springs 88 are connected to the holding device 83 of the respective scratch spring 88 . In the operating and separating state, the spring sections 82 of the scraper springs 88 are deflected vertically and press the scraper lugs 81 against the respective support rail 1, in the separated state against the second support rail, in the fixed state against the second and against the first support rail. For better understanding, the support rail 1 with the coupling 8 arranged therein and its scratch springs 81 is shown in its rest position in FIG. 10b for the sake of explanation. In any case, FIG. 10b shows that the scratch springs 81 must be deflected when the coupling 8 is arranged in the support rail 1. So that the coupling 8 can be removed from the second mounting rail 1 in a simple manner, as shown in FIG. For this purpose, the Stromleitbahnen protective cap 3 is arranged relative to the second support rail 1 and the scratch springs 88 that it presses with its second wing part 331 against the spring section 82, as shown in Figures 10d and 10e. By moving the conductor rail protective cap 3 in the longitudinal direction X relative to the second mounting rail 1 and to the coupling 8 , the scratch springs 88 are increasingly deflected further until their scratching lugs 81 are detached from the second mounting rail 1 . In the course of this relative movement of the conductor rail protective cap 3 along the longitudinal direction X to the second mounting rail 1 and coupling 8, the first wing part 332 comes into contact with the contact surface provided by the receptacle 860, as a result of which the conductor rail protective cap 3 reaches its dismantling position, in which the system continues to be in the Release state is, so release position and disassembly position are identical. By continuing the relative movement of the conductor rail protective cap 3 relative to the second mounting rail 1 in the longitudinal direction X, during which no further relative movement of the conductor rail protective cap 3 to the coupling 8 can take place, since these are in positive contact with one another with respect to the longitudinal direction X, the coupling 8 can easily be disengaged be pulled out of the support rail 1 along the longitudinal direction X.
