Abstract

A contact slide unit for a switch unit, where the contact slide unit includes a contact slide with a switching piece displaceably guided therein, and method for mounting the contact slide unit, where the displaceable switching piece is protected on the contact slide against twisting via a separately formed anti-twist stop.

First claim

The invention claimed is:

1. A method for mounting a contact slide unit for a switching unit having a contact slide with a movable switching piece having two protrusions arranged in a mirror-inverted manner opposite one another and guided therein, the method comprising:
introducing the movable switching piece obliquely between lateral guides of the contact slide;
straightening up the movable switching piece on feet of the contact slide;
introducing a rotation prevention device into an opening in the contact slide; and
aligning the rotation prevention device with the movable switching piece in the contact slide to bear against the two protrusions of the movable switching piece after the rotation prevention device is rotated to its final mounting position;
wherein the rotation prevention device is configured in a U-shaped manner with a support plate as a central region with two guide webs arranged laterally thereon.

2. A contact slide unit for a switching unit, comprising:
a movable switching piece;
a contact slide having the movable switching piece guided therein; and
a separately configured rotation prevention device;
wherein the movable switching piece is positioned in the contact slide in a manner such that it is prevented from rotating by the separately configured rotation prevention device; and
wherein the rotation prevention device is configured in a U-shaped manner with a support plate as a central region with two guide webs arranged laterally thereon.

3. The contact slide unit as claimed in claim 2 , wherein the rotation prevention device is a stamped and bent sheet-metal part.

4. The contact slide unit as claimed in claim 2 , wherein the guide webs of the rotation prevention device have first insertion bevels.

5. The contact slide unit as claimed in claim 4 , wherein the first insertion bevels are arranged on the rotation prevention device in a mirror-inverted manner opposite one another.

6. The contact slide unit as claimed in claim 5 , wherein second insertion bevels, upon which the first insertion bevels of the rotation prevention device are guided during the positioning of the rotation prevention device in the contact slide, are arranged in the contact slide.

7. The contact slide unit as claimed in claim 4 , wherein second insertion bevels, upon which the first insertion bevels of the rotation prevention device are guided during the positioning of the rotation prevention device in the contact slide, are arranged in the contact slide.

8. The contact slide unit as claimed in claim 2 , wherein protrusions are formed on the movable switching piece such that said protrusions hold the rotation prevention device in a manner prevented from rotating in its final mounting position on the movable switching piece.

9. A circuit breaker having a contact slide unit as claimed in claim 2 .
