Description

The invention relates to a system for realizing a lamp according to the preamble of claim 1.

Systems of the generic type have, as two basic components, a support rail which is elongated in a longitudinal direction and a mounting body which is elongated in the longitudinal direction. Supply lines are usually arranged on the mounting rail, and a light source and / or other functional element is usually arranged on the mounting body, such as radio modules, operating devices, etc. Typically, the mounting rail is used to fix the luminaire to a component, for example a ceiling. When assembling a lamp, the mounting rail is usually first attached to the component and then the mounting body, which is equipped with the named components of the lamp that require a corresponding electrical supply, is fixed on the mounting rail, so that the mounting rail and mounting body form an interior space, in which the essential elements of the luminaire are arranged, for example circuit boards with LEDs, operating devices, radio modules, supply lines, etc. Typically, the support rail and mounting body are each designed to be elongated in a longitudinal direction. The support rail usually has a cross section perpendicular to the longitudinal direction, along a The vertical direction is open at a vertical end and is delimited along a transverse direction by two side walls which are connected to one another by a bottom section of the support rail running along the transverse direction. Usually, the support rail is attached to a component via its base section. The mounting body is usually arranged at the open vertical end of the mounting rail, so that the mounting body, together with the mounting rail, forms an interior space which is closed off circumferentially by the mounting rail and the mounting body perpendicular to the longitudinal direction, whereby the enclosure of the interior space can of course be interrupted in sections, for example, to allow an air supply. A generic system usually comprises a power conducting rail which is elongated in the longitudinal direction and which has channels in which conductor wires are arranged, and an electrical contact device with a mounting section and a contact section spaced apart from the mounting section along a vertical direction. In an operating position of the components, also called components, of the system, in which the components of the system have an arrangement to one another that characterizes the operating position and which is necessary for the realization of a lamp, the two basic components are attached to one another, with the conductor rail on a first of the two Basic components is attached and the contact device is attached with its mounting portion to a second of the two basic components and is electrically conductively connected with its contact portion with at least some of the lead wires. In the operating position, the conductor rail is usually attached to the support rail, in particular to the base section of the support rail. However, it is also conceivable that the conductor rail in the operating position on the mounting body, in particular on the bottom portion of the Mounting body is attached. The basic principle of the conductor rail is to enable contacting across a longitudinal section so that contact can be made between the supply lines arranged on the support rail and the components arranged on the assembly body within a specific longitudinal section and not just at a singular longitudinal position. For example, the mounting section of the contact device can be fixed in position on the support rail in the operating position and the contact device can be connected in an electrically conductive manner to electrical supply lines arranged on the support rail, while the power guide rail is arranged on the mounting body and the contact section of the contact device engages in the channels of the power guide rail and contacted the conductor wires arranged in the channels, which in turn are connected to components arranged on the mounting body for supplying the components. Alternatively, for example, in the operating position, the conductor rail can be arranged on the mounting rail, the conductor wires arranged in the channels of the power conductor rail forming at least one section of supply lines which are arranged in the mounting rail, the mounting section being fixed to the mounting body and the contact device in the Channels of the conductor rail arranged on the support rail engages in order to contact the conductor wires arranged therein, the contact device being at the same time electrically conductively connected to components arranged on the mounting body in order to supply these components. The contact device thus in principle enables the supply of components arranged on the mounting body by enabling an electrical connection between the supply lines arranged on the support rail and the components. The supply lines can be in addition to power supply lines also include control or data lines. It must be taken into account that, in order to reach the operating position, the mounting body and the mounting rail are moved towards one another along a vertical direction that is perpendicular to the longitudinal direction until they are arranged and fixed to one another. Common retaining springs are known to those skilled in the art, by means of which a mounting body can be fixed relative to a mounting rail. Typically, such retaining springs have a base section for mounting on the assembly body and, at both transverse ends of the base section, a retaining section extending vertically away from the base section, on which a retaining projection is provided that extends outward in the transverse direction. This retaining projection typically engages behind a fastening projection which is arranged on one of the side walls of the support rail assigned to the retaining projection. For this purpose, the mounting body itself is often designed in such a way that it has a cross-section perpendicular to the longitudinal direction in the manner of a U-shape and thus comprises a bottom section and two side wall sections, the bottom section of the retaining spring often being attached to the mounting body by the bottom section being clamped to projections which are provided on the side wall portions of the mounting body, whereby the bottom portion of the retaining spring is pressed against the bottom portion of the mounting body. However, other fastening options are also known, for example by means of screwing, latching or by means of bayonet locks, by means of which a mounting body can be fixed to the mounting rail. In general, suitable fastening means, with which the assembly body is fastened to the mounting rail in the operating position, are preferably used to prevent the mounting body and mounting rail from moving vertically away from one another, starting from the operating position.

In principle, a large number of common contact devices are known in the prior art, via which the contact between the mounting body and the mounting rail or between components arranged on the mounting body and supply lines arranged on the mounting rail is possible by means of a conductor rail. The contact devices are always designed in such a way that they have contact sections with which they can be introduced into the ducts of the conductor rail. For example, it is known to attach a fixed tap to a conductor rail that contacts the conductor wires arranged in the channels of the conductor rail, this tap forming the contact section of the contact device and being connected to a mounting section via a cable, wherein the conductor rail and the mounting section are attached to different basic components are. However, such contact devices are expensive to produce and complex to assemble. There are also known contact devices that are to be attached to one of the two basic components with their mounting section, the power conducting rail is attached to the other of the two basic components and the contact device has such electrical contact sections that when the mounting body and support rail are vertically brought together, the contact sections in the ducts of the conductor rail are introduced and contact the conductor wires arranged therein. This solution allows inexpensive production of the contact device and simple assembly of the components of the system for reaching the operating position. However, this solution also has various disadvantages. For example, fastening means, such as retaining springs or latching connections, do not offer such a fixability of the mounting body to the mounting rail, that the vertical position of the mounting body relative to the mounting rail is always precisely and unchangeably fixed at any load. For example, vibrations or vertical movements of room ceilings can take place in buildings, for example due to the effects of movement from the floor above the room on the ceiling or due to movement effects on the ground near the building. In the event that a relative movement occurs between the mounting rail and the mounting body, there is a risk that arcs will occur within the interior space enclosed by the mounting rail and mounting body if the contact device with its contact section is diverted from the conductor wires of the conductor rail, which can cause fires . In the prior art, this problem is prevented by providing a sufficient contact length between the contact section and the lead wires and by providing special mechanisms to ensure the smallest possible distance between the mounting rail and the mounting body. However, both require expensive production and influence the free availability of the interior for lighting components. It is also known that the conductor rail with its conductor wires and support rail and mounting body are made of different materials which have different thermal expansion behavior. There is therefore the risk that there will be a relative movement between the contact device fastened to the second basic component relative to the conductor rail while the contact device is in electrical engagement with the conductor wires of the conductor rail. This can lead to stresses and reduced durability, in particular also to the creation of a torque between the conductor rail and the contact device. Such a torque brings the danger with the fact that a relative force is generated between the mounting body and the mounting rail, which works towards a loosening of these two basic components starting from the operating position, so that only a small additional relative force between the two basic components can lead to a loosening of the basic components from one another. In addition, there is a risk that the contact section will lose its electrical connection to the lead wires of the conductor rail.

The present invention is based on the object of providing a system for realizing a lamp which at least partially eliminates at least one of the problems described above or one of the disadvantages of the generic systems described above.

As a solution to the stated object on which the present invention is based, the invention proposes a system having the features of claim 1.

The system according to the invention is suitable for realizing a lamp. The system comprises as two basic components a support rail which is elongated in a longitudinal direction and on which supply lines are arranged, as well as an assembly body which is elongated in the longitudinal direction and on which a lighting means and / or a functional element is arranged. The illuminant and / or other functional element is an element that is to be supplied electrically. The system has a power conducting rail elongated in the longitudinal direction with channels in which conductor wires are arranged, as well as an electrical contact device with a mounting section and a contact section offset along a vertical direction relative to the mounting section. In the operating position, the two basic components are attached to each other and the mounting section and contact portion attached to each other. The mounting section and the contact section can be designed as two separate components, which are combined with one another to form a cohesively fixed component; they can also be designed together as a single-piece component. In the operating position, the conductor rail is fastened to a first of the basic components, and in the operating position the contact device is fastened with its mounting section to a second of the two basic components and is electrically conductively connected to at least some of the conductor wires with its contact section. Particularly preferably, in the operating position, the conductor rail is fixed on the support rail and the mounting section of the contact device is fixed on the mounting body. The mounting body and the mounting rail are particularly preferably fastened to one another in the operating position by fastening means which prevent the mounting body from moving away from the mounting rail along the vertical direction. Particularly preferably, the mounting body and the support rail are designed to correspond to one another so that they are guided to one another along the vertical direction to reach the operating position until they reach a vertical end position, in which case they are fixed to one another by fastening means in this vertical end position. The second basic component has a bottom section and two side wall sections extending away from the bottom section along the vertical direction. In the operating position, the mounting section is held on the second base component, pressed against the base section. In the operating position, the contact section overlaps vertically with the conductor rail with a vertical engagement section and is held fixed on the conductor rail by a contact force acting within the engagement section between the conductor rail and the contact section and with at least some of the lead wires of the power supply rail connected in an electrically conductive manner. The engagement section thus defines a section along the vertical direction, within which the conductor rail and contact section overlap in the operating position. In this overlap area, ie within the vertical extent of the engagement section, the contact force acts between the conductor rail and the contact section, preferably directly between the conductor rail and the contact section. The contact force counteracts a displacement of the contact section relative to the conductor rail starting from the operating position. For example, the contact force can bring about a frictional connection between the conductor rail and the contact section in the engagement section. It must be taken into account that the conductors are encompassed by the conductor rail. However, a form fit can also be provided within the engagement section between the conductor rail and the contact section, wherein the form fit can also bring about a contact force between the conductor rail and the contact section. In this case, in order to carry out a relative movement of the conductor rail and the contact section to one another, starting from the operating position, a force must be generated relative between the conductor rail and the contact section that the contact force is overcome, whereby it may also be necessary that this relative force be applied between the contact section and the conductor rail Contact force significantly exceeds if a relative movement is to be brought about between the contact section and the conductor rail, if there is a form fit within the engagement section between the conductor rail and the contact section. It must be taken into account that in the present case the contact force is preferably generated exclusively by the arrangement formed by the conductor rail and the contact section. For generating a relative movement of the contact section to power guide rail starting from the operating position, with the focus on the relative arrangement of contact section and power guide rail to each other, when they are in the operating position, a force defined with reference to this arrangement consisting of power guide rail and contact section must be overcome so that power guide rail and Contact portion can be moved to each other, regardless of the other influences of other components of the system in the operating position. In any case, to carry out a relative movement between the contact section and the conductor rail, it is necessary to overcome the contact force which is accordingly present between the conductor rail and the contact section in the operating position. According to the invention, a spring device acting between the mounting section and the second basic component is provided, which in the operating position presses the mounting section with a spring force vertically against the bottom section of the second basic component to fix the mounting section to the second basic component. In the operating position, the assembly section is therefore in any case, in particular exclusively, fixed relative to the second basic component in that the spring device exerts a spring force vertically on the assembly section in the direction of the bottom section of the second basic component. This spring force is less than a vertical minimum force which is required to overcome the contact force for performing a vertical relative movement between the contact section and the conductor rail, usually referring to a relative movement of the contact section along the vertical direction starting from the operating position away from the conductor rail. This is based on the contact force that results from the arrangement of the contact section and conductor rail. The vertical minimum force can be defined, for example, via the contact section and current conducting rails are brought into such a position relative to one another in which they are relative to one another in the operating position of the system. The arrangement of conductor rail and contact section created in this way, starting from this position, which this arrangement also has in the operating position, is then subjected to a force which acts relatively between the contact section and conductor rail. In any case, this force must exceed the minimum force so that the contact section can be moved relative to the conductor rail. In one embodiment, the minimum force can be determined, for example, so that a relative force is generated between the mounting rail to which the conductor rail is attached, or directly between the conductor rail and the contact section, and its magnitude is increased until the contact section is relative to the power guide rail moves, this resulting total amount is set as the minimum force. Of course, the amount of the minimum force can be different for different directions of the minimum force. The minimum vertical force is the amount of the minimum force along the vertical direction. The spring device can be formed, for example, from the second basic component or from the mounting section. The spring device is particularly preferably formed only by the mounting section. In one embodiment, the spring device can be formed partly by the second basic component, partly by the mounting section. The system according to the invention can have further features which are explained above in connection with generic systems.

The system according to the invention has significant advantages compared to generic systems. In that the mounting section is fixed relative to the second basic component by a spring device, in that the spring device presses the mounting section vertically against the bottom section of the second basic component with its spring force, it is ensured that the mounting section can be removed from the bottom section of the second basic component along the vertical direction starting from the operating position, ie starting from its position in the operating position along the vertical direction relative to the second basic component is deflected when only a force exceeding the spring force is applied against the spring force on the mounting section relative to the second basic component. Since the spring force is less than the vertical minimum force that is required to overcome the contact force and to perform a vertical relative movement between the contact section and the conductor rail, it is ensured that when the two basic components move relative to one another, for example if there is a movement of a ceiling which the mounting rail is attached, there is a relative movement between the mounting body and the mounting rail, the contact section can remain unchanged in the same position relative to the power guide rail that it occupies in relation to the power guide rail in the operating position of the system. Because with a vertical deflection of the assembly body relative to the mounting rail, the assembly section can initially detach from the bottom section of the second basic component. Since the spring force is less than the minimum force required to overcome the contact force and to carry out a vertical relative movement between the contact section and the conductor rail, the contact section can remain without changing its position relative to the conductor rail during the deflection of the spring device, starting from its position in the operating position.

In one embodiment, the mounting section is starting releasable from the operating position of the bottom portion of the first basic component along the vertical direction by applying a release force exceeding the spring force, while the spring device presses the mounting portion unchanged with the spring force towards the bottom portion of the second basic component. Starting from the operating position, the mounting section is preferably releasable from the bottom section of the first basic component along the vertical direction by applying a release force that exceeds the spring force and acts between the two basic components, in particular acting exclusively between the two basic components, while the spring device keeps the mounting section unchanged with the spring force presses towards the bottom section of the second basic component. In the system according to the invention, a deflection limitation provided between the assembly section and the second basic component is preferably provided in the operating position, which limits a vertical deflection with which the assembly section can be removed vertically from the bottom section of the first basic component by the release force, starting from the operating position, to a maximum deflection. The maximum deflection is preferably less than 5 mm, in particular less than 3 mm, in particular less than 2 mm. Particularly preferably, the deflection limitation between the mounting section and the second basic component is provided in such a way that when the mounting section and the second basic component are arranged in relation to one another that corresponds to the arrangement of the mounting section and the second basic component in the operating position, the vertical deflection with which the mounting section is caused by a release force that acts along the vertical direction between the mounting section and the second basic component, starting from the stated position of the mounting section relative to the second basic component being vertically removable from the bottom section of the second basic component, on the maximum deflection is limited. The deflection limitation is particularly preferably provided independently of the first basic component. The deflection limitation is particularly preferably provided exclusively between the second basic component and the mounting section. The deflection limitation is particularly preferably implemented by a section of the mounting section and a corresponding section of the second basic component. The provision of the deflection limitation can be particularly effective in preventing the mounting section from becoming detached from the second basic component, since this ensures that the spring device can only be deflected until the mounting section is relative to the second basic component, starting from its position relative to the second basic component in the operating position with the maximum deflection.

Particularly preferably, at least one of the side wall sections has a projection pointing towards the opposite side wall section, the spring device having a spring arm which presses vertically upwards against the projection and which presses the assembly section vertically downwards against the bottom section of the second basic component. Particularly preferably, each of the two side wall sections each has a projection facing the opposite side wall section, the spring device having a spring arm at its transverse ends that points vertically upwards against the respective projection of the respective side wall section assigned to it. A transverse end is an end of the spring device along the transverse direction, the transverse direction being perpendicular to the vertical direction and perpendicular to the longitudinal direction. The spring device particularly preferably has four spring arms, two of the spring arms each forming a pair of spring arms, the facing each other in the transverse direction, the two pairs of spring arms being spaced from one another along the longitudinal direction. Particularly preferably, the spring arms of a pair of spring arms each form a transverse end of the spring device. Particularly preferably, the two pairs of spring arms each form a longitudinal end of the spring device. Particularly preferably, each of the spring arms, as explained for the one spring arm, presses vertically upwards against the projection of the side wall section on which the respective spring arm is arranged. By providing four such spring arms, a particularly reliable fixation of the assembly section relative to the second basic component or to the bottom section of the second basic component can be ensured.

The assembly section particularly preferably comprises a body made from sheet metal that forms a support section with which the assembly section rests in the operating position on the bottom section of the first basic component, preferably rests directly on the bottom section of the first basic component. The body also forms at least a part of the spring device in that the body forms the spring arm which, in the operating position, rests on the projection with a vertical pressing force which presses the assembly body against the bottom section of the first basic component. The body particularly preferably has at least four spring arms, each of which in the operating position rests against the projection of the side wall section assigned to it with a vertical pressing force which presses the assembly body against the bottom section of the first basic component. In this embodiment, the assembly body is pressed against the bottom section of the first basic component from the sum of the pressing forces which are generated by the at least four spring arms. Particularly preferred the spring arms are arranged as explained above in order to ensure a particularly reliable fixing of the mounting section on the bottom section of the first basic component. By providing a body made of sheet metal, which is encompassed by the mounting section and designed as explained, a mounting section and part of the spring device with the properties explained can be implemented in a particularly simple manner. Particularly preferably, the spring arm is designed as a scratching nose at its end pointing vertically away from the bottom section of the second basic component in the operating position, which in the operating position preferably establishes electrical contact between the contact device and the second basic component. When a plurality of spring arms is provided, at least one of the spring arms preferably has such an end designed as a scratching nose. Particularly preferably, the end of the spring arm, which is designed as a scratching nose and points away from the bottom section of the second basic component, rests against the projection of the side wall section in the operating position. As explained above, it is particularly preferred that the spring arm or arms always bear against the projection of the side wall section even when the mounting section is deflected from its position in the operating position relative to the bottom section up to the maximum deflection. In general, particularly preferred are the bottom section, side wall sections and protrusion, in particular the protrusions of the side wall sections, each of the side wall sections each having a protrusion, the second basic component being made from sheet metal, in particular by reshaping the sheet metal. The projection of the side wall section is particularly preferably formed by a fold, the fold and thus the projection forming one end of the side wall section. This can apply accordingly when each of the side wall sections each has a projection pointing towards the opposite side wall section. By producing the base section, side wall sections and projection or projections of the second basic component from a one-piece sheet metal, the basic component with its required properties can be produced in a particularly simple and inexpensive manner.

Particularly preferably, the mounting section has a delimiting projection which is vertically spaced from the projection of the side wall section in the operating position and which rests against the projection when the mounting section is maximally deflected vertically relative to the second basic component. In the operating position, the limiting projection is preferably arranged vertically below the projection of the side wall section, while the spring device presses the mounting section vertically downwards against the bottom section of the second basic component. During the maximum deflection, the delimiting projection can, for example, lie indirectly against the projection, for example by having a sheet metal section of the mounting section against the projection during the maximum deflection, against which the delimiting projection comes to rest during the maximum deflection. Such a sheet metal section preferably has an extension of less than 5 mm between its point at which it rests against the projection during the maximum deflection and its location at which it rests against the limiting projection during the maximum deflection. Particularly preferably, the delimiting projection rests directly on the projection during the maximum deflection. This enables a particularly hard stop of the limiting projection and thus a particularly precise setting of the maximum deflection. The delimiting projection is particularly preferably formed by a plate-like section of the mounting section, its flat extension forms an angle of less than 30 °, in particular less than 15 °, relative to the vertical direction. The delimiting projection is thus formed by a section which is designed in the manner of a plate. Such a plate has a flat extension, the area of which is substantially larger than its edge area. The flat extension thus forms the plate surface of the plate. Since the flat extension of the plate-like section of the mounting section, which forms the limiting projection, forms a small angle to the vertical direction, it can be ensured in a particularly advantageous manner that the limiting projection forms a hard stop in the event of a vertical load and can thus precisely define the maximum deflection, since the limiting projection or the plate-like section then acts as little elastic as possible on such a vertical force. Particularly preferably, in the operating position, the delimiting projection overlaps in the transverse direction with the projection of the side wall section. Since the delimitation projection overlaps transversely with the projection of the side wall section, a reliable stop of the delimitation projection and thus a precise definition of the maximum deflection can be supported. Particularly preferably, the side wall section is elastically deflectable relative to the bottom section of the first basic component along the transverse direction and / or the delimiting projection forms a transverse end of the mounting section, which can be elastically deflected relative to an opposite transverse end of the mounting section along the transverse direction. In this particularly preferred embodiment, it can be ensured that, on the one hand, the mounting section can be fixed to the bottom section in a simple manner by the limiting projection along the vertical direction past the projection of the side wall section in the direction of the bottom section can be guided towards the mounting body, the limiting projection in the operating position nevertheless being able to overlap with the projection of the side wall section. In general, it is preferably provided that the assembly section has a plurality of delimiting projections, each delimiting projection being assigned to exactly one projection of a side wall section, that is to say exactly to one side wall section and thus its projection. Particularly preferably, four such limiting projections are provided, analogous to the four spring arms advantageously provided as explained above, whereby two pairs of limiting projections can be provided corresponding to the two pairs of spring arms explained above, which are distributed analogously to the two discussed pairs of spring arms on the assembly section can be provided.

In one embodiment, the spring device overlaps in the operating position in the transverse direction with the projection of the side wall portion, the side wall portion being elastically deflectable relative to the bottom portion of the second base component along the transverse direction and / or the spring device forming a transverse end of the mounting portion with which it is in the Operating position rests against the projection with a vertical pressing force, and this transverse end formed by the spring device is elastically deflectable relative to an opposite transverse end of the mounting section along the transverse direction. Since the side wall section can be deflected relative to the bottom section as explained and / or the transverse end of the spring device is elastically deflectable relative to the opposite transverse end of the mounting section, as explained, it can be particularly advantageously ensured that on the one hand the spring device is reliable in the operating position can be supported on the projection or the projections of the side wall section or the side wall sections in order to press the assembly section against the bottom section of the second basic component, it being possible at the same time to ensure that the assembly section can be fixed in a simple manner to the second basic component, for example by the Mounting portion can be moved along the vertical direction down towards the bottom portion of the second basic component until the spring arm is arranged under the projection of the side wall portion and engages on this and thereby presses the mounting portion along the vertical direction down against the bottom portion of the second basic component
In one embodiment, the mounting section has a guide section on each transverse side, each of the guide sections in the operating position running with a vertical section along one of the two side wall sections of the second basic component assigned to it and in this vertical section by less than 1 mm, in particular less than 0.5 mm, in particular by less than 0.3 mm, in the transverse direction from this side wall section assigned to it. The two guide sections ensure that the mounting section is guided as precisely as possible along the transverse direction relative to the second basic component. This can be particularly advantageous if, starting from its position in the operating position relative to the second basic component, the mounting section is deflected along the vertical direction due to the application of a force as explained above relative to the second basic component. In this case, the guide sections can ensure that undesired movements of the mounting section relative to the second basic component do not occur comes, which can lead to undesired movements of the contact portion relative to the conductor rail.

As a solution to the stated objective technical problem on which the invention is based, the invention also proposes a system for realizing a luminaire which comprises, as two basic components, a support rail which is elongated in a longitudinal direction and on which supply lines are arranged, and a mounting body which is elongated in the longitudinal direction which a light source and / or other functional element is arranged. The system has a power conducting rail elongated in the longitudinal direction with channels in which conductor wires are arranged, as well as an electrical contact device with a mounting section and a contact section offset along a vertical direction relative to the mounting section. In an operating position, the two basic components are fastened to one another and the conductor rail is fastened to a first of the basic components and the contact device is fastened with its mounting section to a second of the two basic components. The second basic component has a bottom section and two side wall sections extending away from the bottom section along the vertical direction. In the operating position, the mounting section is held pressed against the bottom section on the second base component, wherein in the operating position the contact section overlaps vertically with the power guide rail with a vertical engagement section and is held fixed on the power guide rail by a contact force acting within the engagement section between the power guide rail and the contact section, and is electrically conductively connected to at least some of the lead wires. In order to carry out a relative movement between the contact section and the conductor rail, it is necessary to overcome the contact force. The described second solution according to the invention can have further features which are described above in connection with the first solution according to the invention. According to the second inventive solution, a longitudinal guide is provided between the mounting section and the contact section, the contact section being displaceably guided relative to the mounting section along the longitudinal direction by means of the guide and the guide forming a stop at each of its longitudinal ends. The contact section can only be displaced relative to the mounting section within a longitudinal area defined by the stops. The second solution according to the invention has further particular advantages. In particular, the provision of such a guide ensures that the mounting section and the contact section can move relative to one another within a predetermined longitudinal range along the longitudinal direction. This can effectively counteract the generation of stresses between the components of the system in the event of thermal fluctuations. This is because, for example, with a different thermal expansion of the conductor rail, support rail and mounting body, it can then be ensured that such different thermal expansion can be countered by the contact section moving relative to the mounting section without force influences at the transitions or within the engagement section between Conductor rail and contact section occur. In general, the first and second solution according to the invention and the various embodiments thereof described here can be combined with one another. With regard to the geometric dimensions of the mounting section and the contact section, the stops are particularly preferably designed in such a way that the stops cover a displacement path of the contact section within which, starting from the operating position, it is relative to the mounting section is displaceable, allow at least 1 mm, in particular at least 2 mm and / or limit the displacement distance to less than 10 mm, in particular less than 5 mm. The inventors have recognized that specifying a certain minimum displacement distance is particularly advantageous in order to prevent the occurrence of a corresponding voltage between the components of the system over a sufficiently large temperature range. On the other hand, the inventors have recognized that problems can arise when allowing too great a displacement distance, for example if free mobility of the contact section relative to the mounting section is not desired due to electrical contacts or due to the installation space available on the mounting body and / or can lead to damage.

Particularly preferably, a holding force acting between the contact section and the mounting section is ensured by the guide to prevent a displacement of the contact section relative to the mounting section along the longitudinal direction, wherein a displacement force acting in the longitudinal direction relative between the mounting section and the contact section is required for moving the contact section relative to the mounting section, which has a minimum force component along the longitudinal direction to overcome the holding force, this minimum force component in particular being smaller than a minimum force acting along the longitudinal direction, which is required to overcome the contact force and to perform a relative movement along the longitudinal direction between the contact section and the conductor rail. As explained above, the contact section and the conductor rail are in the operating position in a specific position relative to one another, in which the contact force between the conductor rail and the contact section acts. Around To change the arrangement of conductor rail contact section starting from the position it occupies in the operating position so that the contact section is moved relative to the conductor rail along the longitudinal direction, a force is required which in any case overcomes the contact force and to perform a relative movement along the longitudinal direction is suitable between contact section and conductor rail. Since the minimum force component required to overcome the holding force between the mounting section and the contact section is smaller than the force along the longitudinal direction that is required to overcome the contact force to perform a relative movement of the contact section and conductor rail to each other, this can be ensured in the particularly advantageous embodiment that when a relative force occurs between the conductor rail and the contact section, the contact section can remain in its position relative to the conductor rail while it is moving relative to the mounting section starting from the operating position. Thus, the particularly advantageous embodiment can prevent the occurrence of stresses in the system when it is in its operating position and external force influences act on the system, it being possible at the same time to ensure that the contact section is reliably fixed relative to the mounting section. By virtue of the guidance, the contact section is particularly preferably clamped with a holding force in every position of the contact section within the longitudinal region relative to the mounting section. In the operating position, the holding force particularly preferably acts exclusively perpendicular to the longitudinal direction. The holding force can thus bring about a frictional connection between the contact section and the holding section, so that the contact section is only relative to the mounting section with the generation of considerable friction between the contact section and the mounting section can be moved.

In one embodiment, the guide is at least partially formed by reshaping a sheet metal section, the reshaped sheet metal section being encompassed by the mounting section and encompassing a mating section encompassed by the contact section and resting against it in a non-positive manner. Since the sheet metal section is encompassed by the assembly section, the sheet metal section can be particularly well integrated into the assembly section with its other functionalities, the sheet metal section being able to be formed in a simple manner for clamping guidance by reshaping. Since the contact section comprises a mating section and this mating section is encompassed by the sheet metal section and the sheet metal section thus rests against it with a force fit, a particularly good fixation of the mounting section and contact section relative to one another can be ensured. In general, the guide between the contact section and the mounting section is particularly preferably designed such that the guide has a first part, which is formed by the mounting section, and a second part, which is formed by the contact section, the first part being frictionally engaged with a vertical force rests against the second so that the mounting section and the contact section are pressed against one another along the vertical direction and are thereby held against one another. The guide is particularly preferably formed exclusively by the assembly section and contact section.

The assembly section is particularly preferably formed by a first component and the contact section is formed by a second component that is separate from the first. The first component is particularly preferably made from sheet metal. The second component particularly preferably comprises an injection molded body. The sheet metal particularly preferably forms the sheet metal section specified above, which is formed. The injection-molded body particularly preferably forms the above-mentioned second part of the guide. The two components are particularly preferably held to one another via the guide, in particular exclusively via the guide. It is particularly preferred that the two components can be fixed to one another in a captive manner, the two components being in their arrangement that is securely fixed to one another in the operating position.

The invention further relates to a contact device comprising a mounting section and a contact section, the contact device being designed to be used in a system according to the invention. The invention also relates to a lamp which is produced with the system according to the invention, all components of the system being in the operating position in the lamp.

In the Figures 1 to 6 an embodiment of a system according to the invention is shown in various schematic diagrams. In Figure 1 a cross-section perpendicular to the longitudinal direction V is shown schematically while the system is in the operating position. The illustrated exemplary embodiment described comprises a mounting rail 1 and a mounting body 2. Both the mounting rail 1 and the mounting body 2 each have a cross-section in the manner of a U-shape, which is formed by the bottom section and side wall sections. In the in Figure 1 The operating position shown is the mounting body 2 on the mounting rail 1 by in Figure 1 Fastening means (not shown) are held such that the mounting body 2 is pressed with its side wall sections 21 along the vertical direction Z against projections formed by the side wall sections of the support rail 1. In the operating position is also on the support rail 1, namely on its bottom section, a conductor rail 3 fixed. The conductor rail 3 has webs 31 which form channels between them, wherein in the channels in Figure 1 Conductor wires (not shown) are arranged, which are held on the webs 31 of the conductor rail 3 via recesses 310 which are provided in the webs 31. A contact device 4 is fastened to the bottom section 22 of the mounting body 2 by the mounting section 6 of the contact device 4 being pressed against the bottom section 22 of the mounting body 2 along the vertical direction Z. In addition to the assembly section 6, the contact device 4 also has the contact section 5, the contact section 5 being arranged offset from the assembly section 6 along the vertical direction Z.

The relative arrangement of contact section 5, mounting section 6 and mounting body 2 is shown in particular from the perspective illustration according to FIG Figure 2 evident. The contact section 5 has a section 56 with which it rests on a section 66 of the mounting body 6 and is held pressed against this section 66. From the synopsis of Figures 1 and 2 It can be seen that the assembly body 6 has a spring device 61 which forms a scraper 630 at a transverse end, which in the operating position presses from below against the projection 210 of a side wall section 21 of the assembly body 2 assigned to the respective scraper 630 and thereby a support section 65 of the assembly section 6 presses against the bottom section 22 of the mounting body 2. It should be noted at this point that the spring device 61 is shown in its non-deflected rest position in the schematic principle illustrations, which is purely due to the illustration. Of course, the scraper 630 does not extend “into” the side wall section, as shown in the figures Instead, it rests from below on the projection 210 of the side wall section 21 and thereby presses the support section 65 of the mounting section 6 against the bottom section 22 of the mounting body 2. From the overview Figures 1 and 2 It can also be seen that the contact section 5 has webs 51, which are arranged in the channels of the conductor rail 3 in the operating position and press against conductor wires of the conductor rail 3, which are arranged in the channels and are held on the webs 31. In the figures, the electrical contact elements which are provided on the webs 51 of the contact section 5 and which press against the lead wires of the conductor rail 3 in the operating position are not shown.

The schematic structure of the contact section 5 and the mounting section 6 of the contact device 4 is in particular from the schematic basic representations according to FIG Figures 3 and 4 evident. In the present exemplary embodiment, the mounting section 6 is designed as a component that is made from sheet metal, the sheet metal being reshaped for this purpose. The mounting section 6 has a sheet metal section 63 formed by deformation, and the contact device 5 has a mating section formed by projections 52. In the exemplary embodiment described, the contact section 5 has an injection-molded body, both the webs 51 and the projections 52, which form the counter-section, being part of the injection-molded body. The contact section 5 and the mounting section 6 can be fixed to one another in a captive manner by attaching the contact section 5 relative to the mounting section 6 in such a way that the reshaped sheet metal section 63 of the mounting body 6 engages around the projections 52 and the contact section 5 with its section 56 against the corresponding section 66 of the assembly body 6 presses what according to the invention is generally beneficial. In this case, 6 stops 64 are provided on the mounting section. When the contact section 5 is positioned relative to the mounting section 6 as explained and is secured to it in a captive manner, the projections 52 are located between the stops 64. The stops 64 define a longitudinal area within which the contact section 5 moves relative to the mounting section 6 the longitudinal direction X is displaceable. In the operating position, the mating section of the mounting section 5 formed by the projections 52 is spaced apart from all stops 64 of the mounting body 6. This particular is off Figure 5 can be seen, in which the relative arrangement of contact section 5, mounting section 6 and mounting body 2 to one another in the operating position is shown schematically by an enlarged excerpt. From FIG. 5 it can be seen that in the operating position the mating section formed by the projections 52 of the contact section 5 is spaced apart in the longitudinal direction X from the projection 64 of the assembly body 6, which results in the contact section 5 being displaceable relative to the assembly section 6 along the longitudinal direction X, if only a sufficiently high force is applied along the longitudinal direction between these two basic components, via which the holding force acting between contact section 5 and mounting section 6 can be overcome.

From the synopsis of the Figures 3, 4 , 5 and 6 it can also be seen that the mounting portion 6 has a limiting projection 62, which in the operating position shown in the Figures 5 and 6 is shown in schematic excerpts, is arranged offset downwards along the vertical direction Z to the projection 210 of the side wall section 21 of the mounting body 2 and is thus spaced apart from this projection 210 along the vertical direction Z. Further the mounting section 6 has a guide section 67 which, in the operating position, is spaced apart from the projection 210 of the side wall section 21 along the transverse direction Y by less than 1 mm. The mounting section 6 is pressed by the spring device 61 downwards against the bottom section 22 along the vertical direction Z, in that the scraper 630 presses against the projection 210 of the side wall section 21 from below along the vertical direction Z, which is shown in the figures, in particular in FIG Figure 6 is not displayed correctly. The spring device 61 is designed in such a way that when a force that exceeds the spring force and counteracts the spring force is applied, the mounting section 6 with its support section 65 can be moved away from the base section 22 along the vertical direction Z, while the scratching nose 630 of the spring device 63 remains unchanged from below presses against the projections 210 of the side wall portions 21. Since the spring force is less than the vertical minimum force that is required to overcome the contact force for performing a vertical relative movement between the contact section 5 and the conductor rail 3, the system according to the invention can make it possible for a relative movement of the carrier rail 1 to the mounting body 2 along the vertical direction Z to one another , based on the in Figure 1 operating position shown, the mounting section 6 along the vertical direction Z moves away with its support section 65 from the bottom section 22, while the mounting section 6 continues to be acted upon with the spring force along the vertical direction Z on the bottom section 22, at the same time the contact section 5 with its webs 51 remains in engagement with the conductor rail 3 unchanged.
