Fixing bracket for busbars

The innovation concerns a fastening holder for collection loops in electrical systems. It consists essentially of a lower part of insulating material that is placed on a flat surface With a screw or the like. Can be attached and an elastic U-shaped clamping bracket, which is used to define a Busbar is used in one of the receptacles provided in the insulating material lower part.

Such fastening brackets for busbars are used to determine the central, central or earth conductor busbars used in electrical systems. For this purpose, the insulating material base, which can be screwed onto support points in switchgear, is provided with groove-shaped receptacles, into which the busbars, which are different in width and height, are inserted and fixed by means of the U-shaped clamp. Due to the insulating material of the mounting bracket, an electrical separation from the support point, which is usually made of metal, is achieved at the same time _3, whereby the often asked requirement of electrical separation between the center and ground conductors can be met.

Arrangements are _s where the bus bar can be screwed directly to a Isolierstoffblock v <ground known. Of the

Isolierstoffblock is also provided with holes, the one Allow attachment to a level surface. Fastening brackets are also known which consist of an upper and a lower part. The upper part is provided with a recess for fixing the busbar and can by means of screws or the like. be attached to the bottom rope.

A disadvantage of this known execution thread is _; that the busbar is fixed directly or indirectly with screws on the mounting bracket. The assembly of such mounting brackets is not only cumbersome, but also very time-consuming.

The innovation has set itself the task of creating a fastening holder for Sarameljchienen that can be made using Easy-to-manufacture components, the definition of the busbar without the aid of tools and without additional Allows fastening means. In addition, the task of the innovation is to train the mounting bracket so that in their Cross-section differently designed busbars can be inserted and fastened.

According to the innovation, this is achieved in that the insulating material lower part has an undercut on each of its sides perpendicular to the fastening plane, each with a locking tooth from the optionally f ' attachable elastic clamp, which is guided between the outer edges of the insulating material lower part, which is designed as webs behind his thighs

the central part of the clamping bracket, which is bent in the direction of the lower insulating material part, holds the busbar in groove-shaped receptacles provided for this purpose in the lower insulating material part \ without additional fasteners, and that the groove-conveying

migen recordings are designed so that they are the attachment of sealing rails of different cross-sections. According to a preferred embodiment, the expiring Ends of the guide webs on the top surface of the insulating material lower part the groove-shaped receptacles for the busbar. Dao insulating material base is designed in such a way that that a correspondingly arranged recess e.g. Versenkhahruniz. the attachment by means of a screw or the like. on a flat surface.

The innovation is based on only one embodiment Illustrative drawing explained in more detail, namely show:

PIg. 1 shows the view of the fastening holder lower part according to the invention in half cut

Fig. 2 is the top view of the same and

3 shows the side view of the lower part of ^{the fastening holder in the Sch u} .t with attached clamping bracket and integrated busbar

As can be seen in particular from FIG. 1, there is the mounting bracket for busbars from a lower part of insulating material (1) and an upper part, which is a U-shaped clamp. (2> is trained. The lower part (1) is here with a stepped? Bore (3) provided, which aufebener a fastening by means of a screw Pad allowed. Laterally arranged webs (4) serve to guide the U-shaped clamping bracket (2) and protrude so far beyond the top surface of the insulating material lower part "that they have groove-shaped receptacles (11, 12, 13) with their ends (5) form for the busbar (10). In these recordings (11, 12, 13) projections (l4) are arranged so that collective Schierxen different Width and height can be inserted. The lower part of the insulating material is on the sides perpendicular to the »mounting plane (1) each provided with an undercut (6), which with the upper part of one past tooth each (7,8)

the leg of the U-shaped clamp (2.) comprises earthen. The middle part (9) of the U-shaped clamping bracket (2) is provided with a bend, whereby the busbar (10) in one of the groove-shaped recordings (11, 12, - 13) without additional Fixing means is set.

The "advantages" that can be achieved with the innovation exist in particular that with the mounting bracket the 'definition of Sanffifels ^ fed ^ snen ekr »e 2iihiif # sewir. © v-os; ¥ © rlc2eug, and without 'zu = additional fastening means can be made, whereby the assembly tent is reduced significantly.
