Abstract
Official abstract text for this publication.
The disclosure relates to a pole part of a circuit-breaker arrangement having an insulation housing for accommodating a vacuum interrupter containing a pair of corresponding electrical switching contacts, wherein a fixed upper electrical contact is connected to an upper electrical terminal molded or assembled in the insulation housing and a movable lower electrical contact is connected to the insulating housing by a support plate of the insulation housing via a flexible conductor that includes a first end for attaching the flexible conductor to the lower electrical terminal and a second end for attaching the flexible conductor to the movable lower electrical contact. The second end of the flexible conductor is provided with an inside thread which is screwed to an outside thread arranged on the distal end of the movable lower electrical contact.
First claim
Opening claim text (preview).
What is claimed is: 1. A pole part of a circuit-breaker arrangement, comprising: an insulation housing for accommodating a vacuum interrupter having a pair of corresponding electrical switching contacts, wherein a fixed upper electrical contact is connected to an upper electrical terminal molded or assembled in the insulation housing and a movable lower electrical contact is connected to an electrical contact element of the insulation housing via a flexible conductor including a first end for attaching the flexible conductor to the insulation housing and a second end for attaching the flexible conductor to the movable lower electrical contact, wherein the second end of the flexible conductor has an inside thread which is screwed to an outside thread arranged on a distal end of the movable lower electrical contact, and wherein on the distal end the movable lower electrical contact has an inside thread that receives a threaded stud; and a screw-nut for securing the flexible conductor on the movable lower electrical contact, wherein the screw nut is screwed on the thread of the threaded stud and is arranged between the distal end of the movable lower electrical contact and a pushrod, the pushrod being axially attached to the movable lower electrical contact via the threaded stud which is screwed in the inside thread of the movable lower electrical contact. 2. The pole part according to claim 1 , wherein the first end of the flexible conductor is provided with at least one through hole for connecting the first end of the flexible conductor by corresponding screws to insulation housing by a support plate. 3. The pole part according to claim 1 , wherein the flexible electrical conductor consists of copper material in the form of a fleece or a fiber material.
