Description

Track system

The invention relates to a busbar element, in particular for laying in living rooms or the like. Or for installation in wall elements for living rooms or the like. Consisting of an essentially U-shaped profile, the side legs of which have fixing devices for covering the busbar or the like. Like. Are provided, at least on the bottom of the profile a neutral, a ground and a chamfer parallel to the side legs open, the ground is preferably arranged between the chamfer and the neutral, further an adapter part for it with at least one contact pin for at least one Chamfer, the grounding and at least one neutral conductor of the busbar element, an adapter rotating part, the back of which is provided with at least one contact surface per contact surface of the adapter fixed part and the front of which has a receptacle for conventional plugs, and a socket adapter with a plug section for Interaction with standard S Teckdosen and a connection adapter with at least one outlet and / or connection for data lines on its front facing away from the power rail, especially for ISDN lines or the like.

So far, electrical cables have been permanently installed in living rooms or offices, business premises and the like, and sockets have been attached at specified locations and in a specified orientation. In order to be able to set up and operate electrical devices at any location, the use of extension cables, distributors and the like is necessary, which is not visually appealing on the one hand and can also be dangerous because you can trip over the open cables, unintentionally disconnected connectors electrical equipment can be knocked over or torn down. It also often happens that angled plugs must be used in unfavorable positions in which larger cable loops are formed or through which the arrangement of several such plugs next to one another is no longer possible.

Cable ducts or cable ducts are known in which separate cables can be routed together, but the sockets are also provided in fixed positions and cannot be arranged and easily changed according to changing needs of the user. From DE 36 32 414, on the other hand, a power distribution rail is known in which two electrical conductors and a protective conductor are arranged, inter alia, on the bottom of a carrier with an essentially U-shaped cross section. It is also described to arrange the protective conductor between the electrical conductors. In the described power distribution rail, however, undesirable deformations of the side legs of the carrier profile can lead to loosening or even detachment of the additional components attached to the ends of the side legs. Also in the conductor rail of EP 0 159 078 with its conductors essentially at the bottom of a support profile, a plug adapter is attached as an additional component to the outer ends of the side legs of the support profile. Therefore, this construction also has the disadvantage just described that the deformation of the side legs can loosen or even detach the additional component.

The US-PS 3,337,697 has the subject of a busbar for trolleybuses, in which there are completely different requirements than in the aforementioned busbars for living rooms or the like. In addition, this busbar is designed to interact with a movable power take-off device and only has similarities in the arrangement of conductors on the bottom of the open support profile.

The object of the present invention was therefore a system for supplying electrical energy in living rooms or the like, which is quick and easy to install and can be adapted and changed in accordance with the changing needs of the user, with particular attention being paid to the secure attachment of additional components shall be.

This object is first achieved according to the invention in that in the busbar element at the bottom of the profile an open holding profile runs parallel to the side legs, the side parts of which protrude from the bottom of the profile and project towards the other side part. This means that the current can be removed at any point along the busbar element without the need to lay cables and adjust their length. By changing the length of the busbar element or by stringing together several such elements, the possibility can be created along the entire space to provide power connections at any point, to change their position or to remove them again. In this case, the busbar is preferably covered between the power connections in order to avoid contamination and also to prevent the endangerment of living beings in the living space. The configuration according to the invention allows the installation of additional parts, such as plugs or the like, at any point along the length of the busbar element, any deformations of the remaining parts of the element, in particular of its side legs, not hindering the assembly of the additional parts or their loosening or even detachment from the busbar is avoided as far as possible.

In order to facilitate the installation of power connections, it is provided according to a further feature of the invention that an additional leg runs parallel to the side legs within the side legs and outside the conductor tracks. The structures to which the power connections can be fastened are thus separate from the structures to which the cover can be fastened. If, according to a further feature of the invention, the lower section of the additional legs on its side facing the center of the busbar element has at least one conductor track running in the longitudinal direction of the busbar element, there is greater flexibility in the connection components which can be coupled to the busbar, and at the same time therewith the connection of these connection components cannot be negatively influenced by forces of the contact elements directed away from the busbar.

The greatest possible influence over deformations and thus the safety and simplicity of mounting additional parts on the busbar element is given when the holding profile runs over one of the conductor tracks, preferably centrally above the ground. There is also the additional advantage that the earthing of the mounted additional part can be carried out in a simple manner via a conductive fastening element.

To solve the problem, the adapter fix part also contributes, which according to the invention is characterized in that a conductive contact surface is provided per contact pin on the side of the adapter fix part opposite the bottom of the busbar element and that at least one conductive, elastic element is one of each contact pin away from the contact surface and exerting force on the chamfer or the neutral conductor. This adapter fix part can be used to easily and functionally ensure the conductive connection between the busbar and the consumers connected to it, while compensating for any tolerances during manufacture and any deformations when installing the busbar element.

According to a further feature of the invention, axial contact pins can be provided and in each case at least one elastic element is clamped axially oriented between the contact surface and the contact pin.

Alternatively or additionally, there may also be radial contact pins and each radial contact pin is then conductively connected to one of the contact surfaces, at least one preferably conductive elastic element acting on the radial contact pin with a force directed radially outward.

In order to simplify the assembly of additional parts such as sockets or the like, it is advantageously provided in this adapter fixed part that a bushing for a holding element interacting with the holding profile of the busbar element, preferably arranged centrally, is provided.

The secure attachment of the additional parts to be mounted on the adapter fixed part can be ensured in that, according to a further feature of the invention, at least one guide lug is provided on the side with the contact surfaces, the or each guide lug preferably resulting in a closed circular structure with one another, the preferred as coaxial to the central axis between the contact surfaces. This ensures a precisely aligned attachment and conductive coupling of the additional parts, which is aligned with the contact surfaces of the adapter fixed part, whereby in the case of the circular design there is the possibility of securely coupling the additional part in any desired orientation.

In order to enable any orientation of the plug with a simple assembly without additional internal lines and secure conductive coupling to the busbar, it can be provided according to a further feature of the invention that the contact surfaces are formed in a circular arc around the central axis of the adapter fixed part and preferably at least extend over a quarter of the circumference.

According to a further feature of the invention, an adapter rotary part is provided for coupling to the adapter fixed part described above, which is characterized in that at least one receptacle for ensuring an optimally conductive contact with the adapter fixed part and the alignment that is also important for this purpose in every installation position on its rear side any guide lugs of the adapter fixed part is provided, preferably coaxially, but radially outside of its central axis.

If a bushing for a holding element, preferably through the central axis, is provided, this simplifies the assembly of the above-mentioned components, advantageously only one connecting and holding element extending through all parts is necessary, which, in a conductive version, also has the grounding of the to the Connected consumers are allowed.

Preferably, a holding element is rotatably held in the bushing in the adapter rotating part, the section protruding from the adapter rotating part extending through the bushing in the adapter fixed part into the interior of the holding profile of the busbar element. This guarantees the earthing in connection with the holding function and at the same time the simplest assembly.

The simplicity of assembly and also the displacement or removal of said adapter parts at or from a specific position along the busbar can be further increased if the holding element has a head which is radially widened on two opposite sides. By simply turning the holding element, this can be brought into positions in which it can be inserted or removed from the projecting strips of the holding profile or in which the widened sections of the head reach behind these strips and thus fix the additional parts on the conductor rail.

According to a further feature of the invention, it is provided in a special embodiment of the adapter rotating part that the contact surfaces are formed in a circular arc around the central axis of the adapter rotating part and preferably over at least a quarter of the Extend the circumference and the contact surfaces are stationary relative to the receptacle for the connector. As a result, any orientation of the plug can be achieved with simple installation without additional internal lines and safe conductive coupling to the busbar.

In order to be able to connect a current rail according to the invention to existing sockets in a simple and safe manner, a socket adapter is provided, the plug pins and ground contacts of which are connected to preferably resilient contact elements, which contact elements are geometrically present in an arrangement corresponding to the arrangement of the conductor tracks on the current rail element. This also makes it easy to install the busbar according to the invention in existing rooms which were previously conventionally supplied with electrical current.

A detachable connection of the plug pins and grounding contacts to the contact elements is provided for the greatest possible flexibility and for adaptation to different socket designs, preferably via screw terminals.

To include data lines of all kinds, which can advantageously be installed in the busbar elements, such as ISDN lines or the like, according to a further feature of the invention, a connection adapter with at least one outlet and / or connection for data lines on its Front facing away from the busbar, in particular for ISDN lines or the like, is provided. This is characterized in that the back is provided with at least one insulated spacer pin, which comes to rest against at least one of the conductor tracks during assembly.

For simple and rapid installation and displacement to basically any desired location along the busbar, a holding element is rotatably held in the bushing in this connection adapter, the portion protruding from the connection adapter extends into the interior of the holding profile of the busbar element.

To implement a quick and easy-to-use fixation, the connection adapter is advantageously designed in such a way that the holding element has a head which is radially widened on two opposite sides.

The busbar element S in the basic version (see FIGS. 1a and 1b) consists of an essentially U-shaped profile, preferably with side legs 2 adjoining a flat base 1 at right angles. In this first embodiment, the base 1 is preferably for assembly on walls W, walls or the like. Advantageously extended on both sides to the outside by mounting lugs 1a. In these mounting lugs 1 a, bores, slots 1 b, predetermined breaking points or the like are provided at certain intervals, through which the busbar element S can be mounted on the wall W via, for example, screw and dowel arrangements D. The side legs 2, the height of which can be designed differently depending on the application and / or the planned plastering thickness, can also have further, in this embodiment shorter, mounting lugs 3 on their outside facing away from the wall W, which can essentially end with the plastering V. The profile is preferably made of a plastic material with good insulating properties. In order to mount additional parts regardless of susceptible deformation of the side to give legs 2 a good hold and not to hinder their installation and removal, are advantageously provided inside the side legs 2, parallel to these, starting from the bottom 1 of the profile additional legs 4, in or on which receptacles for the additional parts can be provided or that can represent this recording themselves. The area between the side legs 2 and the additional legs 4 can be used as a cable channel K for, for example, TV, data, telephone lines or the like. Elastic lips 5 are provided between side legs 2 and additional legs 4, into which strips 6 of a cover profile 7 engage and fix them to the busbar S. This cover profile 7 can be designed, for example, with predetermined breaking points or, as will be explained later in connection with FIG. 8, in sections lined up in order to adapt it to any length between intended mounting points for additional components or to open openings for these additional components at these points create through which these additional components access the busbar S and / or can be attached to it.

Preferably between the additional legs 4 there are conductor tracks, preferably three conductor tracks 8, 9, 10, of which - as explained further below - the middle track 9 is advantageously used as grounding and the two outer tracks 8 and 10 as chamfer and as neutral conductor. In order to be able to fix additional components quickly and easily at any point, a holding profile is provided on the bottom 1 of the busbar element S parallel to the side legs 2 and the additional legs 4. This holding profile consists of two further side parts 11 starting from the bottom 1 with cantilevered strips 12 in the upper end region directed towards the respective other side part. A conductor path, preferably the middle path 9 for grounding, lies between the two side parts 11 of the holding profile.

Another basic embodiment of the busbar element S according to the invention is shown in FIGS. 2a and 2b, this element being designed for installation with wall cladding panels P, for example plasterboard panels or the like. Instead of mounting flags 1 a as lateral extensions of the base 1, the base 1 closes essentially flat with the side legs 2. In contrast, the front mounting lugs 3 are extended and come to rest on the cutouts of the plates P for the busbar S. 3 slots 3a, bores, predetermined breaking points or the like are provided at certain intervals in these front mounting lugs for carrying out the arrangements, which are common with these plates P, from clamps K and clamping screws R which engage behind the plates P. Here too, the height of the busbar element S can be designed differently depending on the thickness of the plates.

Although the busbar element S can in principle be of any length and can be cut to any desired length, for rational production and warehousing it is necessary to have certain, predetermined lengths, for example in length. 1m, 2m and 4m, an advantage. Two adjacent busbar elements can be held in a spatially constant position relative to one another by the assembly, but a connection via the system shown in FIGS. 3a and 3b is advantageous. In this case, a groove 2a extending in the longitudinal direction of the busbar is provided in the outwardly facing surfaces of the side legs 2, the side of which extends towards the bottom of the busbar element S and runs obliquely outwards from the center of the channel 2a. The bottom of the groove 2a is thus wider than its opening, it forms a semi-dovetail-shaped guide. A connecting element C encompasses the adjoining end sections of two busbar elements S, this connecting element C having an essentially rectangular profile with a base 36 and two side legs 37, which parts preferably lie entirely on the back of the base 1 and the side legs 2 of the busbar S element. Of course, the mounting tabs 1a must be removable or omitted at the connection points, a further area on the side, free of mounting tabs 1a, allowing the connecting element C to be moved laterally, and thus a simpler connection and a simple subsequent release of the coupling. At the front ends of the side legs 37 of the connecting element C are complementary to the cross section of the groove 2a in the side legs 2 of the busbar element S, hook-shaped sections 38 are formed, which hold the connecting element C on the or each busbar element S at most slidably and a Prevent accidental removal or falling. FIG. 3a also shows an electrical connecting element E, which will be explained in more detail in connection with FIGS. 5a to 5c.

A plug adapter shown in FIGS. 4a and 4b can be inserted between the additional legs 4 and is designed for insertion and electrical connection with conventional plugs, ie as a replacement for the usual sockets. The plug adapter consists of an adapter fixed part F to be connected to the busbar element S and a movable adapter rotating part B placed thereon, into which the conventional plug can be inserted. The adapter fixed part F has a preferably square or rectangular housing 13 made of insulating material, preferably again plastic, of which at least one of the outer dimensions corresponds exactly to the width between the legs 4. To establish a conductive contact with the conductor tracks 8 and 10 of at least the chamfer and the neutral conductor, in this first embodiment axially oriented contact pins 14 are provided at a distance from one another which corresponds to the distance between these conductor tracks 8, 10. On the side of the housing 13 opposite the contact pins 14, as can be seen in FIG. 4d, there are contact surfaces 15 on the side of the adapter fixed part F facing away from the bottom of the busbar element S, the conductive connection between the contact pins ten 14 and the contact surfaces 15, for example, each via a conductive spring element, and / or a conductive guide piece 16a with spring 16 or in a similar manner, which exerts a force that the contact pins 14 away from the contact surface 15 and thus in the axial direction in with respect to the adapter fixed part F on the conductor tracks 8, 10 and out of the housing 13. For fastening the adapter fixed part F by means of an additional component (as will be explained further below), a bushing 17 is provided centrally in the housing 13, through which the additional component can be guided and to the holding profile 11 on the busbar S. Finally, 18 also denotes a guide lug or an arrangement of guide lugs, which is preferably designed as a circular and coaxial bar running around the feedthrough 17 and allows a further component to be positioned precisely aligned with the contact surfaces 15 in any orientation with respect to the rotation about the central axis.

Such a component to be put on is preferably the adapter rotating part B, the housing 19, again made of insulating material, preferably plastic, on the front side (see FIG. 4c) advantageously designed like a conventional socket and there with receptacles 20 for the contact pins of conventional plugs and with conductive contact elements 21 is provided. On the rear side of the housing 19, which faces the adapter fixed part F, contact surfaces 22 are provided for making contact and establishing electrical contact with the contact surfaces 15 of the fixed part F. The contact elements 21 are preferably screwed to the contact surfaces 22, but in any case are conductively connected.

The contact surfaces 15 of the adapter fixed part F are preferably designed in the form of a circular arc and extend over an angle of preferably approximately 90 ° coaxially to the central passage 17 for the holding and fixing element. As a result of this configuration of the contact surfaces 15, the adapter rotary part B in the illustrated embodiment can be mounted in two positions on the busbar S, each rotated by 90 °, which permits corresponding positions of the plug to be used. In the case of a circular housing, any intermediate positions could also be adopted. The merging in any installation position precisely aligned with the contact surfaces 15 of the adapter fixed part F is provided by a strip 24 which runs coaxially around the central, preferably circular part of the adapter rotating part B, an annular receptacle 25 being formed between this strip 24 and the central part. When assembling the adapter rotary part B and the adapter fixed part F, the guide tab 18 of the adapter fixed part F comes to rest in this receptacle, which always remains in the same orientation to the busbar S regardless of the orientation of the adapter rotary part B. A snap connection between the flag 18 and, for example, the strip 24 can be provided for coupling the adapter rotary part B and the adapter fixed part F, for example a circumferential one Protrusion 18a engages in a circumferential groove 24a and in this way rotation about the central axis, but not axial pulling apart of adapter rotating part B and adapter fixed part F is permitted.

As the component holding the adapter fixed part F and the adapter rotating part B and fixing these two parts to the busbar, the holding element 26 in its preferred embodiment can be seen as a bolt extending through the bushings 17 and 23 in the adapter fixed part F and adapter rotating part B. This holding element 26 has a head, which is preferably provided with two laterally projecting sections 27 (see FIGS. 4a and 10a). In a rotational position of the holding element 26, these sections 27 engage behind the strips 12 on the side parts 11 of the holding profile on the bottom 1 of the busbar S and thus fix the components to be mounted thereon. The head of the holding element 26 preferably comes into contact with the conductor 9 for earthing and can thus provide the earthing of the consumers supplied with electrical current via the socket of the adapter rotating part B. The second end of the holding element 26, which is advantageously designed as a screw head 28, can at the same time serve as an abutment for a spring element which exerts a force which pulls the holding element 26 out of the holding profile with suitable rotation. The screw head 28 is advantageously screwed back onto the holding element 26 itself and suitably secured. Furthermore, the holding element 26 establishes the connection between the grounding contacts 29 in the rotating adapter part B and the grounding conductor 9 of the busbar S and is made of electrically conductive material for this purpose.

Via the said connection, corner pieces can also be used, which are designed, for example, for traversing corners of the room at a certain angle, preferably 90 °. At most, corner pieces with changeable angles, i.e. with a pivot axis extending in the plane of the bottom 1 of the busbar element S and a movable conductive connection of the conductor tracks 8, 9 and 10 across this axis. Finally, long conductor rail elements S can also be designed to be angled.

In addition to the mechanical connection of two adjacent busbar elements S, for example via the connecting element C, the conductive connection between these elements S must also be established, which can be accomplished, for example, via plug connections or resilient contact tabs. A further advantageous variant, which additionally increases the mechanical stability, is shown in FIGS. 5a to 5c. In this case, an electrical connecting element E is provided which can be slidably inserted between the legs 4 of the busbar elements S in the longitudinal direction. It has a handle 31 on the base body 30 for easier handling. In the longitudinal direction three Rically conductive rods or plates 32 are mounted on the underside of the base body 30, which come into contact with the conductor tracks 8, 9 and 10 and have a cross-sectional shape that combine a secure hold in the structures of the side legs 4 and the holding profile 11 with displaceability in the longitudinal direction . The ends of the rods 32 can be made narrower for easier penetration into the structures of the busbar elements S (see FIG. 5c).

A similar electrical connecting element E '(FIGS. 5d, 5e) can be provided for connecting further electrical systems via conventional conductor wires. For this purpose, screw terminals 33 are provided on the base plate 30 in conductive connection with the rods or plates 32, in the openings of which the ends 34 of conductor wires can be clamped by means of clamping screws 35. The connection to the busbar S is the same as for the connecting element E of FIGS. 5a to 5c.

Conventional electrical lines can also be coupled at any point on the busbar S via a junction box I according to FIGS. 6a and 6b. This junction box I has a housing 36 which is provided with two lateral extensions 36a in the form of the busbar elements S and can be connected to these, for example, via the connecting elements C and E described above. About a preferably screw-in socket 37, the electrical conductors L to be coupled to the busbar S are guided into the housing 36 of the junction box I and their ends are fixed there in screw terminals 38, which screw terminals 38 are also connected to conductors L ', the other ends of which are connected to the electrical ones Connecting elements E 'are connected. As shown in FIG. 6c, however, a further busbar can also branch off via a branch piece T, which can be prefabricated or rotatable for any angle and in which case the electrical connection of the branch piece can take place via the connecting elements E.

When using the busbar S according to the invention with wall cladding panels, it is usually necessary to bypass uprights or mounting strips L for the panels P. For this purpose, an intermediate piece Z is advantageously provided, as shown in FIGS. 7a and 7b. It has a central part 39 which is bulged in accordance with the dimensions of the post L, the conductive connection of the conductor tracks 8, 9 and 10 being produced via bent conductor strips 40 to the central part, which conductor strips are fastened by means of screws 41. In order to make the level difference between the middle piece 39 and the remaining intermediate piece Z visible, part of the post L is shown broken away in FIG. 7b.

As shown in FIG. 8 in a longitudinal section through the center of the cover 7 of the busbar S according to the invention, this cover 7 can be made up of sections 7 a and 7 secured and held together for assembly by an adhesive strip 47 running in the longitudinal direction 7b exist, the longitudinal dimensions of which essentially correspond to those of the plug adapter. This means that the section 7a or 7b only has to be removed at the corresponding point at which a plug adapter is to be mounted and the plug adapter is to be inserted in its place. In the case of a section 7a overlapping on the outside from the ends of the adjacent sections 7b, the adjacent sections 7b must be swung open or removed and then reinserted, but this is very easily possible due to the plug connection in the elastic lips 5 of the busbar element S. The adhesive strip 47 can be pulled off after the cover 7 has been snapped onto the busbar S.

A socket adapter A, of which an exemplary embodiment is shown in FIGS. 9a to 9d, allows a power rail according to the invention to be connected to an existing, conventional socket and in this way, on the one hand, to retrofit rooms that have already been conventionally supplied, and to provide a safer, more elegant and more aesthetic solution to get the replacement of common distribution sockets with cable connection. For this purpose, the socket adapter A is provided with contact pins 42 which are arranged in accordance with the receptacles 43 of the socket ST and also the grounding contacts. Via preferably detachable connections, such as screw terminals 44, the contact pins 42 are connected via short connecting lines, with contact elements that are resiliently resting on the conductor tracks 8, 9, 10 of the elongated part 45 of the adapter A and are also attached via preferably detachable connections, or directly with these conductor tracks of the busbar. Element S connected conductively. The adapter A can, as shown in FIGS. 9c and 9d, be fixed to the wall by means of a screw and dowel arrangement D next to the socket ST. The electrically conductive parts are protected against contact and damage by a cover 47 at the points at which plug adapters are provided.

For easier and more secure mounting of the plug adapter of FIGS. 4a and 4b on the busbar S, a turning handle M is advantageously provided. This rotary handle M has a disk-shaped body 48 made of insulating material, which has a larger diameter than the rotary part B of the plug adapter, at least over part of its thickness. On the side of the body 48 facing the rotating part B, a screwdriver 49 is fastened, which engages with its tongue 50 into the slot 28 ', cross recess or other recess of the screw head 28 of the holding element 26 and, when the body 48 rotates, this holding element 26 in the same Circumference rotates. Through this rotation, the projecting portions 27 of the holding element 26 can be brought into or out of engagement with the holding strips 11 and the plug adapter can be fixed or loosened again without the technician being in danger of coming into contact with live parts. FIG. 11 a shows in cross section how a connection adapter AD according to the invention is fastened to a busbar element S in a manner that can be detached again at any time. The connection adapter AD for TV, data, ISDN lines LE or the like, which are preferably laid in the region of the cable channel K between the side legs 2 and the additional legs 4 of the busbar S, has an essentially flat front side 51. On this front side 51 is provided at least one bore for the passage of the line LE or at least one conventional plug connection 52. For this purpose, the line LE is led out of the cable duct K, through the housing of the connection adapter AD through to the plug connection 52.

At least one further opening 53 is provided on the front of the adapter adapter AD, which receives the head 54 of a holding element 55, which is preferably in the form of a slotted or Phillips screw. The holding element 55 itself is passed through the connection adapter in the form of an elongated bolt and is held rotatably therein. The section of the holding element 55 protruding from the connection adapter is guided into the interior of the holding profile 11, 12 of the busbar element S. Here, too, the head 56 coming to lie inside the holding profile 11, 12 is preferably radially widened on two opposite sides and can be locked in the holding profile 11, 12 when it is rotated about its longitudinal axis, it also releasably detaching the connection adapter AD from the busbar element S. fixed. As described above for the adapter fixed part F and the adapter rotating part B, a spring acting on the holding element 55 could also be provided here, which in the inserted state acts upon this holding element 55 with a force directed away from the busbar element S, in order to secure the connection in this way close.

At least one spacer pin 58 is provided on the rear wall 57 facing the busbar element S (see also FIG. 11c), four spacer pins 58 being present in the illustrated embodiment. These spacer pins 58 keep the housing of the connection adapter AD at the correct distance from the busbar S, so that it cannot be pressed too far and damage it. The spacer pins 58 advantageously come to lie on the outer conductor tracks 8, 10 and are therefore expediently made of insulating material or provided with end pieces made of insulating material. The entire connection adapter AD is advantageously made of insulating material, preferably plastic. In FIG. 11 c, the opening 59 in the rear wall 57 of the connection adapter AD can also be seen more clearly, which serves to lead the cable LE out of the busbar element S to the front side 51 of the connection adapter AD.

As can be seen in the perspective view in FIG. 12a and in cross section in FIG. 12b, in the side walls 4, 11 of the busbar element S, on the other and so that the sides of the element S facing the opposite grooves 60 are incorporated. These grooves 60, which run in the longitudinal direction of the busbar, are arranged at a height above the conductor tracks 8, 10, wherein several pairs of mutually opposite grooves 60 can also be provided at different heights, and can cover 61 as protection against undesired and unintentional contact with the conductor tracks 8 , 10 are inserted in the longitudinal direction. Furthermore, it can be seen in FIGS. 12a and 12b that the conductor rail elements S can in principle be of any desired height, an embodiment with a lower height than in the other drawing figures being shown here as an example, which is suitable for attachment with lower plastering thicknesses . In order to prevent mortar or other building materials from getting into the interior of the busbar S during installation, the plaster cover 62, which can be replaced after installation, is provided for the permanent cover (see, for example, FIG. 1a, cover 7). The side mounting lugs 1 a can also be made smaller, as shown.

13 shows a cross section through a completely installed busbar S, fastened to the wall W and finally with a thin layer of plaster V in the front. In the lateral cable channels K, for example, data or telephone cables or the like LE are drawn in. The fastening elements D, for example a screw and dowel arrangement, are also provided in the region of the cable ducts K and are accessible for assembly or disassembly through these ducts K, so that each of the side tabs of the busbar S and thus the entire busbar can be made narrower. Since the plug adapter, consisting of the adapter fixed part F and the adapter rotating part B, protrude from this due to the lower height of the busbar element S, a cladding or protective element SE is placed, which can advantageously be fixed on the adapter fixed part F by means of a snap connection .

In this further embodiment, the holding element 26 which holds the adapter fixed part F and the adapter rotating part B and fixes these two parts to the busbar S is again designed as a bolt with a head, preferably with two laterally projecting sections 27 (see also FIGS. 4a and 10a ). These sections 27 engage - as already described above - in a rotational position of the holding element 26, the strips 12 on the side parts 11 of the holding profile on the bottom 1 of the busbar S and thus fix the components to be mounted thereon, the head of the holding element 26 preferably being attached to the Conductor 9 comes into contact for grounding. The second end of the holding element 26 is provided with an end piece 28a, again advantageously designed as a screw head, which is provided with a spring lock 28b and is connected to the holding element 26. In this embodiment, there is no need to provide a spring which applies a force directed away from the busbar S to the holding element 26. In another way, the embodiment of FIG. 14a offers protection against unwanted touching of the conductor tracks 8, 10. Here, the side parts 11 of the holding profile and the lower sections of the additional profile legs 4 are significantly widened, so that only thin slots remain open which the thin and preferably flat tongue-shaped contact pins 14 are guided through to the conductor tracks 8, 10. 14a as well as FIG. 14b again show a busbar S in a higher version, which - as shown - is advantageously suitable for installation in mortised or milled-out wide grooves in the masonry W, which is then also covered by a layer of plaster V can be covered. Here, too, in order not to have to make the grooves in the masonry W excessively wide, the attachment by means of, for example, screw and dowel arrangements D can take place through the two lateral cable channels K of the busbar S.

In the embodiment of FIGS. 14a and 14b, the lower sections of the profile legs 4 have additional conductor tracks 8a and 10a, which on the inwards, i.e. sides facing the center of the busbar element S are provided. These can be used in addition or as an alternative to the conductor tracks 8, 10 on the bottom of the busbar S.

In the further embodiment shown here, the adapter fixed part F has two radial contact pins 14a, which bear against the lateral conductor tracks 8a, 10a and which produce the electrically conductive contact. The contact pins 14a are subjected to a force by radially acting elastic elements 16b, preferably springs, and pressed against the conductor tracks 8a, 10a. The grounding is still realized by means of the holding element 26 which also produces the mechanical coupling and which comes into contact with the grounding 9 laid on the bottom of the busbar element S. The conductive connection between the conductor tracks 8a, 10a and the contact surfaces 15 is made via conductive connecting pieces 16c which are located inside the adapter fixed part F and are preferably pressed by means of elastic elements 16 against the contact surfaces 15 and against which the elastic elements 16b for the radial contact pins 14a are supported manufactured on the front of the adapter fixed part F.
