[0022] FIG. 4 an alternative embodiment of the assembly shown in FIG. 3,

[0023] FIG. 5 two assemblies from FIG. 3 to be assembled together to form a luminaire strip,

[0024] FIG. 6 the luminaire elements from FIG. 5 in the assembled state,

[0025] FIG. 7 the assembly of FIG. 6 with a feed connector of the electrical building supply system pushed onto the feed contacts and a bottom part with a tap adapted thereto and configured as a block,

[0026] FIG. 8 the components shown in FIG. 7 in the final assembly state, FIG. 9 a bottom view of the assembly shown in FIG. 2 according to visual arrow IX in FIG. 2,

[0027] FIG. 10 a bottom view of the assembly shown in FIG. 3 according to visual arrow X in FIG. 3,

[0028] FIG. 11 a section through the closed housing of the luminaire strip shown in FIG. 8, and

[0029] FIG. 12 a tap configured as a block.

[0030] The luminaire connector body 1 shown on the left in FIG. 1 firstly has feed contacts 2. The feed contacts 2 protrude vertically upwards from the luminaire connector body 1 in the vertical direction 3. In the horizontal direction 4 perpendicular to the vertical direction 3, two C-shaped connection contacts 5 are oriented on the luminaire connector body 1. The C-shaped connection contacts 5 pointing in the horizontal direction 4 are mouth-shaped and thus embrace a peripheral edge of the busbar 6 extending in the horizontal direction 4. The busbar 6 carries a touch protection 7 at its free end facing away from the luminaire connector body 1 in horizontal direction 4. The touch protection 7 has a cuboid housing body 8 which surrounds the free end of the busbar 6 and a contact strip 9 which adjoins the housing body 8 in the horizontal direction 4. The contact strip 9 consists of a touch protection 7 visible in FIG. 1 and individual pin contacts arranged in the touch protection 7, which are not visible in FIG. 1.

[0031] In the depiction of FIG. 2, the luminaire connector busbar touch protection assembly shown in FIG. 1 is installed in the hood 10 of a luminaire element housing 11. The rectangle-shaped contact carrier 12, which carries the feed contacts 2, passes through the hood 10 in a rectangle-shaped hood opening 13. Furthermore, the touch protection 7 is latched with a housing body 8 in the inner contour of the hood 10 and the contact strip 9 of the touch protection 7 protrudes in horizontal direction 4 from the hood 10 and thus from the luminaire element housing 11. FIG. 9 shows the bottom view of the same assembly.

[0032] In FIG. 3 and FIG. 10, the mechanical coupling parts 14 designed as brackets are visible. The coupling parts 14 protrude from the end of the hood 10 facing away from the contact strip 9 of the touch protection 7 in the horizontal direction 4, and thus from the luminaire element housing 11. The coupling parts 14 are inserted into the receiving means 15 arranged on the luminaire connector body 1. The receiving means 15 are formed as a groove. The coupling parts 14 are inserted into these grooves on the receiving means 15 as tongues to form a tongue-and-groove connection. Furthermore, the coupling parts 14 are positively guided in guides 16 on the inner sides of the side walls 17 of the hood 10.

[0033] FIG. 4 shows a modified version of the assembly shown in FIG. 3, with only the differences being discussed below. In the assembly shown in FIG. 4, the feed contacts 2 are deactivated by placing a deactivation hood 18 over the feed contacts 2 and the contact carrier 12. Furthermore, in the embodiment shown in FIG. 4, the touch protection 7 protrudes from the luminaire element housing 11 in the horizontal direction 4 both with part of its housing body 8 and with its contact strip 9.

[0034] In the depiction of FIG. 5, two hoods 10 pre-assembled according to FIG. 3 are placed one behind the other in the horizontal direction 4. If the hood 10 depicted on the right in FIG. 5 is pushed in the horizontal direction 4 into the hood 10 depicted on the left in FIG. 5, the contact strip 9 of the left assembly finally engages in the connection contact 5 of the right assembly. The coupling parts 14 engage in the guides 16 on the inner sides of the side walls 17 of the left hood 10, so that both assemblies are pushed together to form the luminaire strip depicted in FIG. 6.

[0035] To connect the luminaire connector to the electrical supply network of the building, the feed connector 19 is plugged onto the feed contacts 2. The feed connector 19 is connected at the rear to the mains line 20 of the building supply network. In this way, electrical potential from the building supply network is introduced into the luminaire connector.

[0036] Furthermore, FIG. 7 shows the housing bottom 21 acting as a device carrier. The housing bottom 21 is latched to the hood 10 in the final assembly position shown in FIG. 8. Mounted on the housing bottom 21 is the tap block 22 shown in detail in FIG. 12. The tap block 22 carries spring-loaded touch contacts 23 on its upper side.

[0037] FIG. 11 shows the interaction of the busbar 6 and the tap block 22. The busbar 6 consists of an extruded profile which forms a plate-shaped busbar base body 24. U-shaped receiving chambers for copper conductors 25 arranged side by side and running parallel in the horizontal direction 4 are arranged on the underside of the busbar base body 24. The receiving chambers for the copper conductors 25 are open at the bottom so that the spring-loaded touch contacts 23 on the tap block 22 can engage in the receiving chambers from below in the vertical direction 3 and make direct contact with the copper conductors 25.
