whose legs are set 26 inside head. An im Essentially having a C-cross section, that is, channel-like Housing 33 receives the insulator 28 and also leaves one Long opening 31 delimited by paddles 32 free. The example Conductors 27 consisting of copper strips are assigned to the two legs 26 of the insulator 28 in such a way that that they are parallel to each other at a distance, which is so large that the contact members 7 of the distributor pin P can rest elastically against them, the conductors 27 on their upper and lower edges are rigidly fixed on the insulator 28. The insulator 28 is in turn rigid the upper and lower inner surfaces of the housing 33 integrally formed Holding lugs 29 and 30 set, which attack each corner of the insulator, so that the openings 25 and 31 each other correspond.

When the distributor pin P is assigned to the distributor rail H, the cylindrical part 3 of the pin is first inserted into the elongated opening 31 in such a way that the catches 9 of the flange 12 run transversely to the longitudinal direction of the opening 31. If the puddle 12 hits the flanges 32 of the housing 33 and the cylindrical part j> engages on the other hand in the housing above the flanges 32, the pin P and thus also the cylindrical part 3 are rotated 90 ° within the housing 33 * whereby the spring 15 of the distributor pin is compressed. In this rotated position, the lugs 2 of the cylindrical part 3 overlap the housing flanges 32, and at the same time the contact members 7 arranged at the front ends of the lugs 2 are brought into resilient contact with the conductors 27 of the rail H. The catches 9 of the flange 12 engage in the elongated opening of the housing 33, whereby the pin P is guided and secured against rotation. In this position, the fastening member 14 with the upper surface of the flange 12 against the lower surface of the housing automatically due to the upward

acting force of the compression spring 15 pressed so that the flanges 32 are resiliently held between the lugs 2 of the cylindrical part 3 and the flat 12 of the fastening member 14, like from Pig. 3-visible. Under these conditions will an electrical current via the contact surfaces 27 arranged on the rail H and those provided on the distributor pin P. Contact surfaces 7 fed to the wires 8, so that a consumer, not shown, such as one of the lower Lighting device assigned to the end of the distributor pin P and connected to the wires 8 receives power.

Since the fastening member 14 of the distributor pin P is spring-loaded against the distributor rail H, the pin can P freely along the elongated opening 3I in any position move to rail H. In order to fix the distributor pin P in a desired position, it is therefore only necessary that To rotate the actuator 19 so that it moves up on the tube 1, until the fastening member 14 rigidly the lower surfaces of the busbar H is pressed.

Another embodiment of the invention is shown in FIGS. The contact members 7 of the distributor pin P can also be designed so that, like the contact member 7 ¹ ', they are bent into a U-shape, i.e. have an arcuate part a and are provided with a leg part 36 which is elongated transversely to one leg 34 and over which they can be fixed, one ends of the wires 8 being fixed to the leg points 36.

In this exemplary embodiment, the opposing component 3, which has lugs, is provided with a groove 37 of essentially S-shape, which is adjoined in its central area by the central bore 6 for receiving the power wires 8, which in the figure of the component 3 downwardly extending collector tube 1 is provided. Furthermore, the construction

part J has two smaller grooves 38 lying in the extension of the legs of the S-opening. Each free leg 35 of the contact members 7 ¹ is guided in one of the smaller grooves 38 and the leg parts 36 and the wires 8 connected to them engage in the bore 6 so that the arcuate parts a surround the front peripheral surfaces of the component 3 at a distance . A separator kl made of synthetic resin or the like, which consists of a wedge 39 and a cover 40 integral therewith, is placed on the component 3 in such a way that the Kell 39 engages in the bore 6 between the two leg parts 36 around the leg parts 36 to press against the inner wall of the bore 6, whereby the contact members 7 'are held in the bore at a distance from each other, while the cover 40 closes the component 3' and at the same time isolates (Fig. 5), but with the exception of the arcuate parts a of Contact members 7 '. With this arrangement, a distributor pin P is also created, the contact members of which can exert a spring action in the horizontal direction in their arcuate areas protruding from the lateral front ends of the component 3 'due to the one freely movable leg end.

As can be seen from FIG. 7, the contact members are in the untensioned state before they are brought into contact with the conductors 27 of the rail H. If the distributor pin P is inserted into the rail and then rotated 90 ° so that the contact members 7 ¹ engage the conductors 27 ", then in this case too the arcuate parts a of the contact members 7 ¹ are pressed together by the conductors, and the free ones Leg ends 35 of the links 7 'move due to their inherent elasticity along the smaller grooves 38. The arcuate parts a of the contact members 7 ¹ are thus, as shown in FIG relatively closely related to the conductors

connection to this, this makes it possible to use the distributor pin also while maintaining the conductive state between the contact members and the conductors along the Move rail.

According to a further embodiment of the invention shown in FIGS. 9 and 10, the distributor pin P is designed in a modified manner, in particular with regard to the contact members and, if necessary, the fastening means. As can be seen in particular from FIG. 10, the upper end of the component ^ ″, which is also made of synthetic resin or the like. Existing collector tube 1 has a longitudinal recess 42 which is connected to the bore 6 in its central area and is open towards both lateral ends. Each of the contact members 7 ¹¹ consists of a sheet metal strip with a bent free end 44, to which a leg 48 is connected, which, bent down at 45 at a flat angle, continues into a sloping leg part 46, on which a dem Leg J56 (Fig. 6) of corresponding leg 47 connects. Each leg 47 is therefore connected to one end of the wires 8. Two contact members 7 ¹ 'designed in this way are inserted into the recess 42 and the bore in such a way that they are symmetrically opposite to the transverse direction, the legs 48 engaging in the recess 42 such that the bent ends 44 over the ends of the lugs of the component j5 protrude and the legs 46 and the legs 47 connected to the wires 8 Γη the bore 6 are inserted. A also made of synthetic resin or the like. existing and a wedge-shaped part 50 with inclined side surfaces 49 at the upper end and a cover 51 having separating piece 52 is placed on the component 3 in such a way that its wedge-shaped part 50 engages in the bore 6. This wedge-shaped part 30 presses each of the legs 47 of the contact members 7 ″ against the associated inner wall of the bore 6 in order to fix them in their position, and the cover 51 covers the

Recess 42 located legs 48 of the contact members? ' ^f from and isolates them at the same time, while the bent free ends 44 protrude over the laterally open, front ends of the recess 42 in the horizontal direction to the outside.

So there is also a distributor pin due to the third embodiment P available, the contact members 7 ″ of which have a spring action in the horizontal direction at the bent free ends exercise when they are resiliently against the conductors of the busbar.

In this embodiment, the distribution pin is assigned to the distribution rail as follows: while the compression spring 15 analogously encloses the upper area of the collector tube 1 and is covered by the fastening member 14, the lower end of the spring I5 of the third embodiment is from the upper end of the upwardly extending cylindrical part of the plague actuator 22 supported. This cylindrical part has a thread 43 on its circumference - to which the actuating member 19 is assigned * which also has an internal thread, but no upper and no lower locking attachment 16 and I? so that when the actuating element 19 is rotated on the upper region of the plunger actuating element 22 provided with the thread »43, the former can be moved upwards or downwards. In this embodiment, the tube 1 does not have a threaded section. The control element 22 can be fixed in a suitable position at the lower end of the collector pipe 1 by means of the screw 24 in order to leave a sufficient distance between the lower end of the fastening element 14 and the upper region of the fixing element 22, whereby a movement of the operating element 19 is made possible. While so- mL% of the fastening member 14 is movable against the upward force of the spring 15 when a downward force is applied when the actuating member 19 is held in its lower position , the fastening member 14 is by the

Actuating member 19 locked in its upper pre-tensioned position when the latter is brought into its upper end position, where it comes to rest on the lower end of the fastening member 14.

If the actuating member 19 is left in its lower position when the component 3 of the pin 9 is inserted into the rail H via the slot J51 provided on its lower side and rotated, then the bent free ends 44 of the contact members 7 begin due to their horizontal direction acting intrinsic elasticity on the conductors 27 in the rail H to rest. When the distributor pin P is fully rotated by 90 °, the legs 48 of the contact members 7 ^{1f are} pushed back into their rearward position, the inclined legs 46 engaging the recesses formed by the inclined surfaces 49 of the separator 52, so that the frictional pressure of the contact members 7 "reaches its greatest value against the conductor 27 and at the same time the bent ends 44 rest on the conductors in a vertically close operative connection.

According to the invention, the distributor pin is so designed that its contact members at both ends of the upper end dee current collector tube molded component one in horizontal Direction acting spring force exert that the fastening member arranged movably below the component of the pipe is always biased upward in the direction of the rail and that the rail with each other at a distance opposite one another and, opposite the one provided on the lower side of the busbar Long opening vertically arranged ladders is provided. In this arrangement, the distributor pin of the distributor rail is in contact stable, whereby it is automatically assigned by the
