Intermediate piece that can be plugged onto busbars for one

The innovation "concerns a plug-in on busbars Intermediate piece for a circuit breaker.

For the optional attachment of commercially available circuit breakers to busbars, devices are required that enable such an attachment in a simple uncomplicated manner.

The innovation is based on the task of such To create device.

To solve this problem, an intermediate piece of the type mentioned is, according to the innovation, a platform-like machine side trained, cuboid, with fastening means For the machine provided, busbar-side open insulating material housing with several pairs in each case associated with each other incorporated into opposite side walls of the housing, the contours of the busbars Adapted passage slots and one, on the busbars facing side of the housing arranged, with threaded holes for optional, with the passage slots aligned fastening of a metal plate provided with a contact spring encompassing a busbar in a U-shape.

The slots provided make it easier to find the busbars when the intermediate piece is plugged on in an advantageous manner and they take over the leadership of the respectively selected busbar until it is encompassed by the contact spring.

Further details of the innovation emerge from an exemplary embodiment explained in more detail below with reference to four figures. Show it

Fig. 1 shown in an oblique view, the Zv / ischenstück on the busbar side seen;

Fig. 2 the Zv / ischenstück in side view;

Fig. 3 the Zv / ischenstück in plan view of the, the busbars facing side seen;

Fig. 4 shows the intermediate piece with "attached to the intermediate piece Circuit breakers shown interacting with four busbars, the busbars and the

Zv / ischenstück are drawn cut.

In detail, Fig. 1 shows that the Zv / ischenstück essentially consists of a cuboid, open on the busbar side Insulating housing 1 consists. One with screw holes Metal plate 3 is attached to the inside of the insulating material housing facing the busbars. The threaded holes serve to be able to screw a U-shaped contact spring 2 to the metal plate. Opposite Side walls 7 of the insulating material housing v / iron slots 13, which are aligned in pairs with one another and the contours the busbars are adapted. Depending on the assignment of the circuit breaker to a busbar, the contact spring be screwed to the metal plate 3 in such a way that it is aligned with a pair of the passage slots (cf. also Figs. 2 and 4). The side of the intermediate piece facing the automatic circuit breaker is designed like a platform and has means for fastening the circuit breaker. The means exist on one side of the edge of the platform-like Housing wall made of elastic fastening means 4, 5j

which at the same time in an advantageous manner for electrical connection of the circuit breaker are used. These fasteners consist essentially of sheet metal brackets, of which the one 4 integrally connected to the metal plate 2, while the other 5 through a slot of the platform-like trained housing wall is guided and then bent over forms a ground contact. The one opposite the temples The edge of the platform-like housing wall ″ has a groove 14 (FIG. 2). Into this groove (cf. also FIG Pig. 4) web-like parts 16 of the circuit breaker (indicated by dashed lines in Pig. 4) engage. Through this on the on one side elastic, on the other side rigid mounting of the circuit breaker are tension in the Fixing the machine avoided in an advantageous manner.

4 shows four busbars 6 which run on the surface of an insulating plate 16. Insulating plates and busbars are surrounded by a housing-shaped profile on v / iron mounting rail 12. The portrail 12 is applied Earth, so that the automatic circuit breaker 17, which is plugged onto the busbars with the aid of the intermediate piece, over the section 15 of the bracket 5 is connected to ground and via the bracket 4 and the contact spring 2 to a busbar.
