Description

15 20 25 30 35 40 7807228-7 r 2 enables long resilient pins, which can be easily mounted and still provide good holding in the recess belonging to the pin.

This object is achieved in that the bearing bracket according to the invention has obtained the characteristics stated in claim 1. The pockets indicated in the character at the end of the projecting portions prevent the pins consisting of a stirrup and said portions from hooking into each other during insertion into the reversing bridge. They also support the shackle at its open end and stiffen the shackle between its back and its open end through the end fixation.

Similar plug connections are known from banana sockets (non-fiction book "Bauelemente der Feinmechanik", 5th edition, by Richter / Voss, Verlag Technik Berlin, 1952, p. 315). In the solution according to the invention, however, the ends and not, as in the case of banana contacts, the back part of the U-shaped stirrup are pulled up towards the tips. In the bearing bracket according to the invention, a more elastic and break-proof connection is thereby obtained.

This structure also provides high abrasion forces with long pegs, which according to current standards are required with regard to the pulling forces required for the removal of the cover plate.

The stirrup can be easily mounted at the projecting portion and securely attached thereto, if the frame of the bearing bracket in the area of the recess has a partially projecting edge, behind which protruding tabs from the stirrup can fall in when inserting the stirrup, as per se in principle is known (the non-fiction book "Connect element of fine engineering", von Pöschl, Springer-Verlag, 1954, p. 57). The bracket can be inserted particularly easily into the bearing bracket if the U-shaped bracket at its leg ends is clamped to the thickness of the projecting portion next to the recess fl in the frame of the bearing bracket.

The jumper will then be guided at the projecting portion during the insertion.

It is advantageous if the projecting portions have a T-profile, so that the jumper already receives lateral support during insertion.

The invention will be explained in more detail in connection with the exemplary embodiments schematically represented in the accompanying drawings. Fig. 1 shows a bearing bracket, seen from the side. §Ig_å shows the bearing bracket in longitudinal section with attached story-like rocker.

This figure is also a section along the line II-II in Fig. 3. In Fig. 3 is shown in a view from above said bearing bracket with attached rocker. In Fig. 1 a bracket of resilient material is shown, which is a detail in the bearing bracket 7807228 -7 3 bucks. §Ig_§ shows the jumper according to fig 4 from the side. §Ig_§ shows a section through the bearing bracket along the line VI-VI in Fig. 3.

The bearing bracket according to Fig. 1 has projecting portions 2 at its frame 1. Such a portion lies behind the drawing plane and is obscured by the portion shown. Together, two such portions 2 and the frame 1 form recesses 3 (cf. Fig. 6). A U-shaped bracket 4 of resilient material is inserted in the recesses 3. The projecting portions 2 have at their ends pockets 5, which fix the ends of the yoke. 6 denotes a recess in a reversing bridge which supports the movable contact part. The pin, which is formed by the projecting portions 2 and the stirrup 4, fits into the recess 6.

Fig. 2 shows a bearing bracket with a large-surface rocker 7 in cross-section attached by snapping. The rounded tip 8 on the projecting portions facilitates the insertion into the recess 6 in the broken reversing bridge shown. The U-shaped bracket 4 is clamped at its ends to have the same distance as the thickness of the said portions. Fig. 4, which in side view shows the stirrup 4, shows that it has protruding tabs 11, which when inserting the stirrup fall behind a projecting edge 12 according to Fig. 6 at the recess 3. Fig. 6 also shows the pockets 5 for receiving and fixing of the jumper ends clearly.

By means of holes 13 in the flat sides of the stirrup (Fig. 5), the suspension properties of the legs can be affected.

A T-shaped profile of the projecting portion 2 according to Fig. 2 provides the bracket 4 with lateral support during the insertion. The T-profile is seen at a cross-section through the projecting portion 2 perpendicular to the plane of the drawing according to Fig. 2.
