Embodiment Construction

[0048] figure 1 A spring contact according to the invention is shown schematically with a cylindrical spring carrier 1 , which is formed, for example, from a wire with a circular cross section. Arranged on the spring carrier 1 is a cylindrical contact piece 2 , which can likewise be a wire piece. The spring support 1 is made of a conductive elastic material, such as an alloy, such as CuBe2 or a noble metal. The contact 2 is constructed from a solid metal wire comprising a noble metal alloy or a noble metal. An armored wire piece can likewise be used as the contact piece 2 , the sheathing containing a noble metal or a noble metal alloy. Gold alloys are especially suitable as noble metal alloys for the contact piece 2 .

[0049] Both ends of the spring carrier 1 are suitable as contact areas for the spring contacts. The contact area serves to connect the spring contact to a conductor via which a voltage can be applied to the spring contact. At the same time, the spring cont...

Abstract

The invention relates to a spring contact for a sliding contact with a connection region (24) and at least one contact region comprising a spring element and a noble metal, wherein the spring contact comprises an electrically conductive spring carrier (1, 11, 21 , 31) and at least one contact (2, 12, 22, 32), wherein the spring support has substantially symmetrical rigidity in a plane perpendicular to the stretched extension of the spring support and is composed of electrically conductive, substantially Made of noble metal-free material, and wherein at least one contact piece is electrically conductively connected to the spring carrier, the material comprising at least one surface for forming the sliding contact and the surface of the contact piece contains a noble metal or a noble metal alloy. The invention also relates to a slip ring converter comprising such a spring contact, wherein one or several contact pieces rest on the slip ring in an electrically conductive manner, and to an engine with such a slip ring converter and a generator with such a slip ring converter.

Description

technical field [0001] The invention relates to a spring contact for a sliding contact, with a connecting region and at least one contact region, comprising an elongated spring element and a noble metal. [0002] The invention also relates to a slip-ring converter comprising such a spring contact as well as an engine and a generator with such a slip-ring converter. Background technique [0003] Spring contacts for sliding contacts are well known from the prior art. Sliding contacts are used to transfer electrical current from a stationary part of the device to a moving second part of the device. Sliding contacts or sliding contacts are used especially in motors and generators, where electrical current is transmitted to rotating parts. In this case, a so-called slip ring converter is formed, in which the spring contact slides over the slip ring and thus produces an electrically conductive connection of the spring contact to the slip ring. [0004] The contact area is the e...
