Definitions

  • the present invention relates to a switch contact for electrical switchgear, with a contact element that with a contact carrier is connected.
  • From DE-A-15 39 783 are switching contacts for electrical Switchgear known, for example, from a rectangular Contact carbon and a hemispherical metallic counterpart consist.

  • the basic idea of the present invention is in that the contact element and thus that through the contact element button formed into several smaller individual segments is divided. These small individual segments can then be economically welded to the contact carrier connect. This can reduce the cost of manufacture of switching contacts can be significantly reduced. Farther is achieved by segmenting the contact element, that the internal stresses in the contact element or be reduced in the contact area in such a way that even at high switching stress a detachment of contact material is reduced from the contact element.
  • the contact element segments are advantageously without gaps Composed contact element.
  • the segment gap technically seen between the individual contact element segments essentially zero.
  • Through the close juxtaposition of the individual contact element segments becomes almost any size, continuous button generated.
  • the through the seamless joining of the contact element segments resulting shunts about the touching Edges can be easily compensated.
  • contact elements generated with a non-continuous button it is conceivable, for example, that contact elements with corresponding Recesses or the like are formed.

For example, the trailing edges of the contact element made of a different material than the inside of the Contact element or the contact surface. When using a Resistance welding process for connecting the contact element with the contact carrier, the commutation of the Arc on the drain rails are facilitated.

Abstract

L'invention concerne un contact de commutation (10) destiné à des commutateurs, qui comporte un élément de contact (12) connecté ou pouvant être connecté à un support (11) de contact. L'objectif de l'invention est notamment de permettre de connecter, avec une qualité suffisante, des éléments de contact (12) particulièrement grands avec le support (11) de contact, notamment par un procédé économique de soudage par résistance. A cet effet, l'élément de contact (12) est constitué d'une pluralité de segments (13) d'éléments de contact et les différents segments (13) sont assemblés séparément de façon à former ledit élément de contact (12). On peut utiliser des segments (13) constitués des mêmes matériaux ou de matériaux différents et/ou ayant les mêmes formes ou des formes différentes pour obtenir des propriétés de contact différentes.
