Description

The present invention relates to a connector for a light that has a support profile with a rail receiving space in which there is a separating web that divides the rail receiving space into a first rail receiving chamber and a second rail receiving chamber, each of which serves to accommodate a current-carrying rail. The invention also relates to a lamp that is equipped with such a support profile, with such a current-carrying rail and with at least one such plug.

The invention is based on a lamp, as for example from the EP 3 583 606 A1 is known. Such a lamp is equipped with a support profile. The lamp has a linear and elongate shape with respect to its longitudinal direction and is particularly suitable for use in a light strip in which several such lamps are arranged one behind the other in the longitudinal direction. For this purpose, the support profile has a profile body that is straight and elongated with respect to its longitudinal direction and has two opposing lateral profile walls and a profile base connecting the two profile walls to one another. The two profile walls and the profile base delimit a profile interior on three of four sides, while the profile body forms or has a profile opening on a fourth side opposite the profile base. On its bottom inner side facing the profile interior, the profile base forms a rail receiving space, in which a current-carrying rail can be clipped, the rail receiving space being delimited by a first receiving wall and a second receiving wall, which are formed on the profile base and face one another. In the case of the above EP 3 583 606 A1 known lamp is a conventional current-carrying rail is used, which has a linear with respect to the longitudinal direction and elongated rail body, a rail base and several from Rail base has protruding, mutually parallel contact webs. Adjacent contact webs each delimit an engagement groove laterally, that is to say transversely to the longitudinal direction. All contact webs each have at least one electrical conductor, which has a free-standing contact area in one of the engagement grooves, on which electrical contacting is possible. The rail body has a spring bar on each of the two longitudinal sides of the rail base, which interact with the two receiving walls for clipping when the current-carrying rail is inserted into the rail receiving space. In the case of the known lamp, one current-carrying rail fills the entire rail receiving space. The EP 3 583 606 A1 also shows a plug that has a number of plug-in elements corresponding to the number of engagement grooves, so that when the plug is plugged in or mounted, one plug-in element engages in each engagement groove.

In the case of the known lamp, the spectrum of use of the lamp can be changed, in particular, via variants of the current-carrying rail. For example, variants of the current-carrying rail can differ from one another by a different number of electrical conductors arranged therein. Inexpensive variants contain a minimum number of conductors to implement a single circuit. Elaborate, complex variants contain significantly more conductors in order to implement multiple circuits, with one of these circuits in particular also being able to be configured as an emergency circuit. The provision of a comparatively large number of different variants for the current-carrying rail requires a great deal of logistics. Furthermore, the use of simple variants is associated with a comparatively high consumption of material, as a result of which these simple variants are relatively expensive.

From the DE 10 2011 114 160 B4 a lamp is known in which a separating web is formed on the profile base, which divides the rail receiving space into two rail receiving chambers divided, in each of which a current-carrying rail is arranged. An associated plug engages with its plug-in elements in the engagement grooves of both current-carrying rails.

The present invention deals with the problem of demonstrating an advantageous or at least another embodiment for a lamp of the type described above and for the associated plug, which is characterized in particular by reduced production costs with regard to the formation of variants.

According to the invention, this problem is solved by the subject matter of the independent claim. Advantageous embodiments are the subject matter of the dependent claims.

The invention is based on the general idea of designing the support profile on the profile base in such a way that the rail receiving space is divided into two rail receiving chambers running parallel to one another, into each of which a correspondingly smaller current-carrying rail can be clipped. This makes it possible to equip the two rail receiving chambers independently of one another with a current-carrying rail. For example, it can be provided for simple variants to equip only one of the current-carrying chambers with a current-carrying rail, while the other rail-carrying chamber remains free. It is also conceivable for complex variants to equip both rail receiving chambers with one current-carrying rail each. The same current-carrying rails or also different current-carrying rails can be used in the two rail receiving chambers. It is of particular advantage that, in order to implement simple variants in which a single current-carrying rail is sufficient, it is not necessary to equip both rail-receiving chambers with one current-carrying rail each. For these simple embodiments is thus almost a halving of the costs for Conductor rail realized. The same applies to the plugs that are used.

A plug according to the invention for such a lamp can be used as a feeder and serve to feed electrical energy into a current-carrying rail. A plug of this type can also be used as a tap and can be used to tap electrical energy from a current-carrying rail. For this purpose, the respective plug has a plug body which has a plurality of web- or rod-shaped plug-in elements which protrude on a plug side of the plug body and which engage in an engagement groove of the current-carrying rail when the plug is inserted into a current-carrying rail. A rod-shaped plug-in element has a cross-section transverse to the plug-in direction, the width and length of which are approximately the same size. In contrast to this, a web-shaped plug-in element has a cross-section transverse to the plug-in direction, in which the length is significantly greater than the width.

At least one of the plug-in elements has at least one mating contact area which makes electrical contact with a contact area of a conductor of the current-carrying rail when the plug is plugged into the current-carrying rail. The plug according to the invention is now characterized in that the plug body also has a rod-shaped or web-shaped centering element protruding on the plug-in side, which differs from the plug-in elements and which, when the plug is plugged into the current-carrying rail in the area of the separating web, the respective ones adjacent to the separating web and /or contact bridge supported on the separating web laterally, i.e. overlapped transversely to the plug-in direction. In particular, the centering element has no counter-contact area; in particular, the centering element is dimensioned shorter in the plug-in direction than the plug-in elements, as a result of which a collision with the separating web is avoided. The plug according to the invention is thus adapted to the support profile according to the invention, which is characterized by the separating web in the rail receiving space. In the As a result, the plug according to the invention is intended for use in a lamp that is equipped with such a support profile.

The plug body can expediently also have a neutral conductor plug element which protrudes on a side edge of the plug body on the plug side and, when the plug is plugged into the current-carrying rail, engages in a gap which is formed between the contact web adjacent to the spring bar and the receiving wall opposite this contact web. The neutral conductor plug-in element has a counter-contact area which is electrically contacted with a contact area of a conductor of this contact web which is exposed in the intermediate space and faces the respective receiving wall when the plug is plugged into the current-carrying rail. As explained above, the current-carrying rail is configured as a standard current-carrying rail for this purpose, so that the mating contact area of the neutral conductor plug-in element comes into contact with the contact area of the neutral conductor of the neutral conductor contact web. In the case of a current-carrying rail designed as an emergency current-carrying rail, the insertion of the neutral conductor plug-in element into the intermediate space is prevented by the support area and in particular by the cover collar.

The respective plug can be designed as a single plug, in which the plug body has an active area and a passive area on the plug side, which are separated from one another by the centering element. In the case of the single plug, the plug-in elements are only formed in the active area. As a result, with the help of the single plug, an electrical coupling can only be implemented with a single current-carrying rail. In contrast to the active area, the passive area has no plug-in element.

As an alternative to this, the plug can also be configured as a double plug, in which the plug body has a plurality of plug-in elements on both sides of the centering element. As a result, two current-carrying rails can be electrically contacted at the same time with the help of the double plug.

It can expediently be provided that the centering element is arranged centrally or centrically on the plug body with respect to the transverse direction and/or is configured symmetrically with respect to the transverse direction. As a result, the single plug can be plugged in either with the first current-carrying rail or with the second current-carrying rail. With a symmetrical design, the double plug can also be plugged in upside down with both conductor rails.

In another embodiment, on the other hand, it can be provided that the centering element on the plug body is arranged eccentrically or eccentrically with respect to the transverse direction and/or is configured asymmetrically with respect to the transverse direction. In this way, it is possible to prevent a reversed assembly with two different current-carrying rails, especially in the case of a plug configured as a double plug, for example if one current-carrying rail is designed as a standard current-carrying rail, while the other current-carrying rail is designed as an emergency current-carrying rail. In particular, the double plug can be designed as an emergency plug, in which the centering element is designed and/or arranged asymmetrically, so that the emergency plug can only be plugged into two current-carrying rails at the same time if one current-carrying rail is designed as a standard current-carrying rail and the other current-carrying rail is designed as an emergency current-carrying rail. In addition, the selected asymmetry or arrangement of the centering element ensures that only the plug-in elements provided for contacting the standard current-carrying rail can be inserted into the standard current-carrying rail, while only those for contacting the emergency current-carrying rail provided plug-in elements are pluggable with the emergency power supply rail. This measure improves the operational safety of the lamp presented here or of the lamp system presented here.

A light according to the invention, which is particularly suitable for constructing a light band that has several such lights one behind the other in the longitudinal direction, is equipped with a support profile that has a rail receiving space opposite a profile opening in a profile base, in which there is a separating web that separates the rail receiving space in a first rail accommodating chamber and a second rail accommodating chamber. The lamp also has at least one current-carrying rail, which is inserted into the respective rail receiving chamber. In addition, the lamp has a device carrier, which has an elongated and rectilinear carrier body with respect to its longitudinal direction, which carries at least one electrical consumer and which is attached to the carrier profile opposite the profile base and thereby closes the profile opening. Furthermore, the lamp is equipped with at least one plug of the type described above, which is electrically coupled to at least one such current-carrying rail.

The respective electrical load can optionally be electrically coupled to the respective current-carrying rail by means of such a plug. The plug can expediently be electrically connected to the respective electrical load via a cable and plugged into the respective current-carrying rail so that the cables are electrically connected to the conductors of the respective current-carrying rail. The respective load can thus be connected to a circuit that is provided in the respective current-carrying rail.

According to an advantageous embodiment, the support profile has a longitudinally extending separating web on the profile base between the both chamber walls and protrudes into the rail receiving space. As a result, the separating web divides the rail accommodating space into a first rail accommodating chamber and a second rail accommodating chamber. The first rail accommodating chamber is delimited laterally, that is to say transversely to the longitudinal direction, by the first accommodating wall and by the separating web. The second rail accommodating chamber is delimited laterally by the second accommodating wall and by the separating web. The design of the receiving walls and the separating web is such that a first current-carrying rail can be clipped into the first rail-receiving chamber, while a second current-carrying rail can be clipped into the second rail-receiving chamber. The separating web can be a separate component that is attached to the support profile or to the profile base. However, a design is preferred in which the separating web is formed integrally on the profile base. The supporting profile is preferably a shaped sheet metal part made from a single piece of sheet metal by forming, which has the two profile walls and the profile base with the receiving walls and the separating web.

According to an advantageous embodiment, the separating web can form a web undercut in the first rail receiving chamber and in the second rail receiving chamber, on or in which the current-carrying rail possibly clipped therein is supported in a holding direction pointing from the profile bottom to the profile opening. The respective web undercut can be formed, for example, by a projection protruding laterally to the associated receiving wall, on which the respective current-carrying rail can be supported in the holding direction.

In another advantageous embodiment, the receiving walls can each optionally form a wall undercut in or on which the current-carrying rail that may be clipped in is supported in the holding direction. As a result, the respective current-carrying rail can be fixed along its two longitudinal sides in the respective rail receiving chamber. Appropriately can now be provided be that the wall undercuts and the web undercuts differ from each other, especially geometrically. For example, the respective wall undercut can be further away from the profile base in the holding direction than the respective web undercut. The wall undercut and web undercut thus differ in particular in such a way that a contour provided on the respective current-carrying rail for support on the respective wall undercut and not for support with the web undercut can interact. As a result, a mistake-proof installation of the respective current-carrying rail in the respective rail receiving chamber is realized.

In another embodiment, it can be provided that the separating web on the profile base forms a longitudinal groove with an undercut contour on a base exterior facing away from a profile interior. This undercut contour defines an undercut in a mounting direction that is oriented opposite to the holding direction. In order to form the undercut contour, the longitudinal groove has a groove cross section in which a groove width in the interior of the groove, ie at a distance from the groove opening, is greater than in the groove opening. This makes it possible, in particular, to insert a fastening element into the longitudinal groove, which is supported in the longitudinal groove in the assembly direction, ie on the separating web and thus on the profile bottom and ultimately on the support profile. With the help of one or more fastening elements of this type, the support profile can be suspended from a building or room ceiling, for example. Since the fastening element can be moved and positioned within the longitudinal groove along the entire length of the support profile, suspended installation is simplified for the support profile and thus for the luminaire equipped with it.

In another advantageous embodiment, the separating web can divide the rail accommodating space symmetrically, so that the first rail accommodating chamber and the second rail accommodating chamber are mirror-symmetrical. This mirror symmetry refers to a plane of symmetry that is parallel to the longitudinal direction of the support profile and perpendicular to the transverse direction of the support profile, the transverse direction in turn running perpendicular to the longitudinal direction. In this way, incorrect assembly of the support profile can be avoided.

According to another embodiment, the current-carrying rail, which is suitable for use in a support profile of the type described above, can have a rail body that is straight and elongated with respect to its longitudinal direction, which has a rail base and a plurality of contact webs that protrude from the rail base and run parallel to one another. Adjacent contact webs each delimit an engagement groove laterally, that is to say transversely to the longitudinal direction. Several or all of the contact webs each have at least one electrical conductor, which has a free-standing contact area in one of the engagement grooves. Electrical contact can be made with the respective conductor of the current-carrying rail at this contact area. The rail body also has a spring bar on an outer longitudinal side of the rail base, which interacts with the respective receiving wall for clipping when the current-carrying rail is inserted into the first or second rail receiving chamber.

According to an advantageous embodiment, in the case of the current-carrying rail, the rail base and/or that contact web which is arranged on an inner longitudinal side of the rail base facing away from the outer longitudinal side on the rail body can form a support contour which, when the current-carrying rail is clipped into the first or second rail receiving chamber, on the separating web supports. This support contour differs from the spring bar, so that the current-carrying rail is configured asymmetrically with respect to its longitudinal center plane. This ensures that the current-carrying rail is installed in the respective rail-receiving chamber so that there is no risk of confusion. In particular, the spring bar and support body differ from one another in such a way that the spring bar cannot be clipped onto the separating bar, so that the current-carrying rail overall cannot be clipped the wrong way round into the respective rail receiving chamber.

According to an advantageous embodiment, the current-carrying rail can be designed as a standard current-carrying rail, in which the contact bar adjacent to the spring bar is configured as a neutral conductor contact bar and has an electrical conductor that has a free-standing contact area on a side facing the spring bar, which is opposite when the current-carrying bar is inserted into the respective rail receiving chamber the respective recording wall is spaced. This conductor is expediently the neutral conductor, which is required for grounding or as ground in the respective circuit.

Alternatively, the current-carrying rail can be designed as an emergency current-carrying rail, in which the contact bar adjacent to the spring bar has a support area on a side facing the spring bar, which is laterally supported on the respective receiving wall when the current-carrying bar is inserted into the respective rail receiving chamber. In particular, the external contact bridge does not have a conductor that has a free-standing contact area on a side facing the spring bridge. As a result, the emergency power supply rail and the standard power supply rail differ mechanically or geometrically from one another, which allows for confusion-proof installation.

According to a development of the emergency power supply rail, the contact web adjacent to the spring bar can have a laterally protruding cover collar at its end remote from the rail base, which protrudes over the support area on the side facing the spring bar. This covering collar ensures that a plug, which has a neutral conductor plug-in element for contacting the neutral conductor of a standard current-carrying rail, is not incorrect can be mounted around. The covering collar prevents the neutral conductor plug-in element from penetrating into a gap between the external contact web and the receiving wall.

Further important features and advantages of the invention result from the dependent claims, from the drawings and from the associated description of the figures with reference to the drawings.

It goes without saying that the features mentioned above and those still to be explained below can be used not only in the combination specified in each case, but also in other combinations or on their own, without departing from the scope of the invention. Components of a higher-level unit, such as a device, a device or an arrangement that are mentioned above and are to be mentioned below, which are designated separately, can form separate parts or components of this unit or be integral areas or sections of this unit, even if this shown differently in the drawings.

Cross sections as in figure 1 , but in other embodiments, each in two states A and B.

Accordingly figure 1 has a lamp 1 in the figures 1 and 3 to 8 is at least partially reproduced in each case in a cross-section running transversely to the longitudinal direction X, a support profile 2, at least one current-carrying rail 3, 4, at least one device mount 5 and at least one plug 6. The longitudinal direction X is in figure 2 indicated by a double arrow and is in the figures 1 and 3 to 8 perpendicular to the drawing plane. The lamp 1 has an elongated and rectilinear shape with respect to the longitudinal direction X. According to figure 2 the lamp 1 can be used in particular in a light strip 7, in which several such lamps 1 are arranged one behind the other in the longitudinal direction X and directly adjoin one another. The lamp 1 or the light band 7 is intended for suspended ceiling mounting. In figure 2 a ceiling 8 is shown, on which the light strip 7 or the lights 1 are fastened or suspended via a number of fastening elements 9 . The respective fastening element 9 can preferably be a cable or a rod.

Accordingly figure 1 the device carrier 5 has a carrier body 10 which is elongated and rectilinear in relation to the longitudinal direction X and which is preferably produced from a single piece of sheet metal by forming. The carrier body 10 carries at least one electrical load 11. In the example figure 1 the load 11 forms an electrical lighting unit which has at least one circuit board 12 and a multiplicity of light-emitting elements 13, which are preferably light-emitting diodes or LEDs.

The device carrier 5 also has an optical system 14 which is attached to the carrier body 10 in a suitable manner. The respective consumer 11 is supplied with power via the respective plug 6, which for this purpose is electrically connected to the respective consumer 11 via cables (not shown). The plug 6 is plugged into at least one of the current-carrying rails 3, 4.

According to the figures 1 and 3 to 8 the support profile 2 has a profile body 15 which is straight and elongated with respect to the longitudinal direction X and has two opposing lateral profile walls 16, 17 and a profile bottom 18 which connects the two profile walls 16, 17 to one another. The profile body 15 is also preferably a shaped sheet metal part that is produced from a single piece of sheet metal by forming. The profile body 15 defines a profile interior 19 which is delimited on three of four sides by the two profile walls 16, 17 and by the profile base 18 and which has a profile opening 20 opposite the profile base 18. The profile opening 20 is closed by the equipment carrier 5 fastened to the support profile 2 . Here, the carrier body 10 latches with the side walls 16, 17 of the profile body 15.

The profile base 18 has, on its base inner side 21 facing the profile interior 19, a rail receiving space 22, which is delimited laterally, i.e. transversely to the longitudinal direction X, by a first retaining wall 23 and a second retaining wall 24, which are formed on the profile base 18 and extend transversely to the longitudinal direction X opposite. A separating web 25 is also formed on the profile base 18 between the two receiving walls 23 , 24 , which protrudes into the rail receiving space 22 and thereby divides the rail receiving space 22 into a first rail receiving chamber 26 and a second rail receiving chamber 27 . The first rail receiving chamber 26 is delimited laterally by the first receiving wall 23 and by the separating web 25 . The second rail accommodating chamber 27 is laterally through the second accommodating wall 24 and through the separating web 25 is limited. One or the first current-carrying rail 3 is clipped into the first rail-receiving chamber 26 , while the other or second current-carrying rail 4 is clipped into the second rail-receiving chamber 27 . For clipping in the current-carrying rails 3, 4, the separating web 25 forms a web undercut 28 in the first rail receiving chamber 26 and in the second rail receiving chamber 27, respectively. The clipped-in current-carrying rail 3, 4 can be on or in this web undercut 28 in a holding direction 29 pointing from the profile bottom 18 to the profile opening 20, which in figure 1 is indicated by an arrow support. The two web undercuts 28 are realized here by a bulbous configuration of the separating web 25, as a result of which the separating web 25 for each rail receiving chamber 26, 27 forms a projection protruding in the direction of the associated receiving wall 23, 24. To implement the clip connection, the receiving walls 23, 24 each form a wall undercut 30, in or on which the respectively clipped-in current-carrying rail 3, 4 is supported in the holding direction 29. It can be seen that the respective wall undercut 30 is further away from the profile base 18 in the holding direction 29 than the associated web undercut 28. In other words, the web undercuts 28 and the wall undercuts 30 have different geometric configurations.

Preferably, the receiving walls 23, 24, the separating web 25 and, if necessary, the wall undercuts 30 and the web undercuts 28 are formed integrally on the profile base 18 or on the profile body 15.

The separating web 25 forms a longitudinal groove 32 on the profile base 18 on a base exterior 31 facing away from the profile interior 19, which groove forms an undercut or an undercut contour. The longitudinal groove 32 extends in the longitudinal direction X and defines a groove opening 33 in the profile base 18 on the outer side 31 of the base to inside the longitudinal groove 32, whereby the above-mentioned undercut contour is formed. This undercut contour acts in a mounting direction 34, which in figure 1 is indicated by an arrow and which is opposite to the holding direction 29 . The longitudinal groove 32 can be used in particular to fix a fastening element 9 to the support profile 2 in a form-fitting manner. For example, a thickened end 35 of the respective fastening element 9 is inserted into the longitudinal groove 32, for example at a front longitudinal end of the support profile 2 or the longitudinal groove 32.

In the examples shown here, the separating web 25 subdivides the rail receiving space 22 transversely to the longitudinal direction X with mirror symmetry. As a result, the two current-carrying rails 3 , 4 can be exchanged for one another, so that the first current-carrying rail 3 is then arranged in the second rail-receiving chamber 27 , while the second current-carrying rail 4 is arranged in the first rail-receiving chamber 26 .

The respective current-carrying rail 3, 4 has a rail body 36 that is straight and elongated with respect to the longitudinal direction X, which has a rail base 37 and a plurality of contact webs 38 that protrude from the rail base 37 and run parallel to one another. Each two adjacent contact webs 38 can laterally delimit one engagement groove 39 between them. Several or all contact webs 38 have at least one electrical conductor 40, for example made of copper. In the example of figure 1 four contact webs 38 are formed on each current-carrying rail 3, 4, each having one or two such conductors 40. Each conductor 40 has a free-standing contact area 41 which, apart from a conductor 40' serving as a neutral conductor, is arranged in one of the engagement grooves 39 in each case. Furthermore, the respective rail body 36 has a spring bar 43 on an outer longitudinal side 42 of the rail base 37 . When the respective current-carrying rail 3, 4 is inserted into the respective rail receiving chamber 26, 27, the respective spring bar 43 acts with the respective receiving edge 23, 24 or with the local wall undercut 30 for clipping together. Furthermore, a support contour 45 is formed on an inner longitudinal side 44 of the respective rail base 37 facing away from the outer longitudinal side 42 . The current-carrying rail 3 , 4 clipped into the respective rail receiving chamber 26 , 27 is supported via the respective support contour 45 on the separating web 25 or on the web undercut 28 located there. This support contour 45 differs from the spring bar 43. The support contour 45 is shaped and adapted in such a way that it interacts with the undercut 28 of the bar. The spring bar 43 is shaped and adapted in such a way that it interacts with the wall undercut 30 . In particular, the respective spring bar 43 cannot be supported on the separating bar 25 . As a result, the current-carrying rails 3, 4 cannot be clipped into the respective rail receiving chamber 26, 27 upside down.

The support contour 45 can in principle be formed in that a concave recess complementary to the convex outer contour of the separating web 25 is formed on that contact web 38 which is located on the inner longitudinal end 44 of the rail base 37 . Said recess is then located on the side of the respective contact web 38 facing away from the spring bar 43 1 and 2 to 8 In the examples shown, the support contour 45 is formed by a protruding edge of the rail base 37, which protrudes transversely to the longitudinal direction X beyond the contact web 38 on the inner longitudinal side 45. This edge engages in the web undercut 28 .

In the figures 1 , 3 , 5 , 7 and 8th the first current-carrying rail 3 is configured as a standard current-carrying rail 3'. In the figures 4 and 6 the second current-carrying rail 4 is configured as a standard current-carrying rail 4'. In Figures 3 and 4, only one current-carrying rail 3, 4 is installed. In the case of the current-carrying rail 3, 4 designed as a standard current-carrying rail 3', 4', the contact bar 38 adjacent to the spring bar 43 is configured as a neutral conductor contact bar 38' and is equipped with the neutral conductor 40', whose contact area 41 is not arranged in an engagement groove 39, but on a side facing the spring bar 43. The contact area 41 of the neutral conductor 40' is spaced apart from the opposite receiving wall 23, 24 when the current-carrying rail 3, 4 is inserted into the rail receiving chamber 26, 27. As a result, an intermediate space 46 is formed between this outer neutral contact web 38' and the receiving wall 23, 24 transversely to the longitudinal direction X.

In contrast, in the figures 1 , 5 , 7 and 8th the second current-carrying rail 4 is designed as an emergency current-carrying rail 4". In figure 6 On the other hand, the first current-carrying rail 3 is configured as an emergency current-carrying rail 3". In the case of the current-carrying rail 3, 4 configured as an emergency current-carrying bar 3", 4", the external contact bar 38" adjacent to the spring bar 43 is provided with a support area 48 on a side facing the spring bar 43, which located on the respective mounting wall 24 or mounting wall 23 in 6 , Laterally supported when the current-carrying rail 3, 3", 4, 4" is inserted into the associated rail receiving chamber 26, 27. In particular, said intermediate space 46 does not form there. In addition, in the case of the emergency power supply rail 3", 4", the external contact bar 38" can have a laterally protruding cover collar 47 at its end remote from the rail base 37, which protrudes over the support area 48 on the side facing the spring bar 43. It is noteworthy that with the Emergency power supply rail 3", 4" designed power supply rail 3, 4, the external contact bridge 38" thus has no neutral conductor 40'.

The respective plug 6 can be designed as a feeder and can be used to feed electrical energy into the respective current-carrying rail 3, 4 and can be connected to an external electrical energy source such as a building-side power supply system. The respective plug 6 can also be designed as a pick-off and for picking up electrical energy from the respective current-carrying rail 3, 4 are used and connected to a consumer 11. In any case, the respective plug 6 has a plug body 49 which has a plurality of plug-in elements 50 in the form of webs or rods. The plug-in elements 50 protrude from the plug body 49 on a plug-in side 51 . When the plug 6 is plugged into the respective current-carrying rail 3, 4, the plug-in elements 50 each engage in one of the engagement grooves 39. At least one of the plug-in elements 50 has at least one mating contact area 52 which makes electrical contact with the respective contact area 41 of the respective conductor 40 of the current-carrying rail 3, 4 when the plug 6 is properly inserted into the current-carrying rail 3, 4. The connector body 49 also has a rod-shaped or web-shaped centering element 53 protruding from the plug-in side 51 . The centering element 53 is not used for electrical contact and accordingly differs from the plug-in elements 50, in particular geometrically. When plugging the plug 6 into the respective current-carrying rail 3, 4, the centering element 53 overlaps the respective contact web 38 adjacent to the separating web 25 or the contact web 38 supported on the separating web 25 laterally. The centering element 53 is dimensioned significantly shorter than the plug-in elements 50 with respect to the plug-in direction of the plug 6.

In all of the embodiments shown here, the connector body 49 can additionally have a neutral conductor plug-in element 59 which protrudes from a side edge 54 of the connector body 49 on the connector side 51 . When the plug 6 is plugged into the respective current-carrying rail 3, 4, this neutral conductor plug-in element 59 engages in the intermediate space 46 described above and can thereby make electrical contact with the contact region 41 of the neutral conductor 40'. For this purpose, the neutral conductor plug-in element 59 also has a suitable mating contact area 52.

In the examples of figures 1 , 3 to 6 the plug 6 is designed as a single plug 6', in which the plug body 49 has an active area on the plug-in side 51 55 and a passive area 56, which are separated from one another by the centering element 53. The plug-in elements 50 are formed exclusively in the active area 55 . The passive area 56 has no plug-in element 50 . Since the centering element 53 is located in the area of the separating web 25, only a single current-carrying rail 3, 4 can be contacted with the single plug 6'. This single plug 6' can also be referred to as a standard single plug 6'.

In the example of figure 8 the plug 6 is configured as a double plug 6". In the case of the plug 6 configured as a double plug 6", a plurality of plug-in elements 50 are formed on the plug body 49 on both sides of the centering element 53. With the help of the double plug 6" both current-carrying rails 3, 4 can be contacted at the same time.

The centering element 53 is arranged centrally or centrally transversely to the longitudinal direction X so that the plug 6 configured as a single plug 6′ can be plugged in either with the first current-carrying rail 3 or with the second current-carrying rail 4 . This is also the case here with the plug 6 configured as a double plug 6'', in particular when the two current-carrying rails 3, 4 are each configured as a standard current-carrying rail 3', 4'.

In the example of figure 7 the plug 6 is designed as a single plug 6' and also as an emergency plug 6‴, which can also be referred to as an emergency single plug 6‴. Here, too, the centering element 53 can be designed and/or arranged symmetrically transversely to the longitudinal direction X. The emergency plug 6‴ also has a neutral plug element 59, but on the opposite side in comparison to the standard single plug 6′ presented above. As a result, the emergency single plug 6‴ can only be plugged into two current-carrying rails 3, 4 at the same time if one current-carrying rail 3 is designed as a standard current-carrying rail 3', while the other current-carrying rail 4 is designed as an emergency current-carrying rail 4". This correct one condition is in Figure 7A shown. If, on the other hand, the emergency single plug 6‴ is fitted the wrong way around, the neutral conductor plug element 59 collides with the covering collar 47 and consequently cannot be plugged in, which in Figure 7B is shown.

In the application example figure 3 only the first rail receiving chamber 26 is equipped, while the second rail receiving chamber 27 is unequipped. Thus, only the first current-carrying rail 3, which is configured here as a standard current-carrying rail 3', is inserted into the support profile 2. The plug 6 is designed as a single plug 6 ′ and plugged into the first current-carrying rail 3 .

At the in figure 4 shown variant, however, only the second rail receiving chamber 27 is equipped, while the first rail receiving chamber 26 is unequipped. Accordingly, the second current-carrying rail 4 , which is designed here as a standard current-carrying rail 4 ′, is clipped into the second rail-receiving chamber 27 . The plug 6 designed as a single plug 6 ′ is plugged into the second current-carrying rail 4 .

In the variant after figure 5 Both rail receiving chambers 26, 27 are each equipped with a current-carrying rail 3, 4, the first current-carrying rail 3 being configured as a standard current-carrying rail 3', while the second current-carrying rail 4 is configured as an emergency current-carrying rail 4". The plug 6 designed as a single plug 6' is in figure 5 plugged into the first current-carrying rail 3.

In the variant after figure 6 Both rail receiving chambers 26, 27 are each equipped with a current-carrying rail 3, 4, the first current-carrying rail 3 being configured as an emergency current-carrying rail 3", while the second current-carrying rail 4 is configured as a standard current-carrying rail 4' is. The plug 6 designed as a single plug 6' is in figure 6 plugged into the second current-carrying rail 4.

In the figures 7 and 8th Both busbar receiving chambers 26, 27 are again equipped, with the first power supply rail 3 being designed as a standard power supply rail 3', while the second power supply rail 4 is designed as an emergency power supply rail 4". figure 7 shows a plug 6, which is designed as a single plug 6 'and as an emergency power plug 6'. In the active area 56 are the plug-in elements 50 according to Figure 7A engage in the engagement grooves 39 of the emergency power supply rail 4". The neutral conductor plug-in element 59 is located on the side edge 54 facing away from the active area 56, i.e. on the side of the passive area 56, so that the centering element 51 is arranged between the neutral conductor plug-in element 59 and the other plug-in elements 50. The neutral conductor plug-in element 59 acts with the neutral conductor 40' of the standard current-carrying rail 3'.To implement the emergency power supply, both current-carrying rails 3, 4 are therefore required.

In the example of figure 8 the emergency power plug 6‴ is configured as a double plug 6", so that it has plug-in elements 50 on both sides of the centering element 53. Furthermore, the neutral conductor plug-in element 59 is also provided on the side edge 54. Here, too, the neutral conductor plug-in element 59, which is only arranged on one side, in connection with the covering area 47, prevents a Incorrect insertion of the plug 6.

In the example of figure 7 shows how the plug 6 is supported via spring legs 57 on the contours of the profile walls 16, 17 when the plug 6 is fully inserted into the respective current-carrying rail 3, 4. In contrast to this, FIGS. 1 and 8 each show an example in which the plug 6 is latched to the equipment carrier 5 or the carrier body 10 via latching contours 58 . It is clear that in all of the embodiments shown here, either the support with the spring legs 57 or the latching connection with the latching elements 58 can be used.
