Abstract

A switching arrangement includes an interrupter unit with a first and a second switching contact piece. A switching path can be formed between the two switching contact pieces under a relative movement of the same. At least one of the switching contact pieces is arranged within a hollow body. The switching contact piece is supported by a transversal crosspiece that crosses the hollow body. The transversal crosspiece is braced at opposite sections of the hollow body.

First claim

1 - 14 . (canceled)

15 . A switching arrangement, comprising:
an interrupter unit having first and second switching contact pieces movably disposed relative to one another for completing a switching path; at least one of said first and second switching contact pieces being positioned within a hollow body; a cross member supporting said at least one switching contact piece in said hollow body, said cross member crossing said hollow body and being braced against opposite sections of said hollow body.

16 . The switching arrangement according to claim 15 , wherein said hollow body is a rotationally symmetrical hollow body.

17 . The switching arrangement according to claim 15 , wherein said hollow body is a hollow cylinder.

18 . The switching arrangement according to claim 17 , wherein said cross member extends on a diameter of said hollow body.

19 . The switching arrangement according to claim 17 , wherein said first switching contact piece is rod-shaped and extends coaxially with a cylinder axis of said hollow cylinder.

20 . The switching arrangement according to claim 15 , wherein said first switching contact piece has an end seated on said cross member.

21 . The switching arrangement according to claim 15 , wherein said cross member and said first switching contact piece are screw-connected to one another.

22 . The switching arrangement according to claim 15 , wherein said cross member is screw-connected to said hollow body from a radial direction.

23 . The switching arrangement according to claim 15 , wherein said cross member is connected to said hollow body by a tenon and mortise joint.

24 . The switching arrangement according to claim 15 , wherein said hollow body has a recess formed in a lateral surface thereof enabling said cross member to be inserted into an interior of said hollow body through said recess, whereupon a tenon of said cross member is pivoted into a slot.

25 . The switching arrangement according to claim 24 , which comprises a bolt clamped with said cross member to be supported against cheeks of the slot.

26 . The switching arrangement according to claim 24 , wherein the slot opens out into said recess.

27 . A method of mounting a cross member in an interior of a hollow body of an interrupter unit, the cross member being configured for supporting a switching contact piece of an interrupter unit of a switching arrangement in the interior of the hollow body, the method comprising:
providing the cross member with a tenon; inserting the cross member into the interior of the hollow body through an opening formed in a lateral surface of the hollow body; and pivoting the tenon of the cross member into a slot in the hollow body.

28 . The method according to claim 27 , which comprises rotating the cross member about a rotation axis of the hollow body.

29 . The method according to claim 27 , which comprises clamping the cross member to the slot.
