  • Such known socket contacts with resilient contact slats are not able to respond in a regulating manner, in particular progressively, to a heating of the socket contact, as described, for example, in US Pat.

This bimetallic area changes shape due to existing heat. This ensures that the contact normal force remains at least constant or even increases.
  • One of the essential advantages of the invention is that the required contact normal force for gripping the inserted mating contact remains constant or even amplified even with increased power supply.

If the current is amplified, then the conductor and thus the contact blades 10 would heat up on themselves, which in turn would lead to the predetermined by bias voltage contact force F is reduced.

Abstract

L'invention concerne un contact de douille comprenant un élément de connexion (7) et un élément de contact (8). L'élément de contact (8) est formé au moyen d'une lamelle de contact élastique et à fixation (10). En raison d'une alimentation de courant élevée, il se produit à l'intérieur du contact de douille (6), un échauffement pouvant éventuellement occasionner une relaxation des lamelles de contact (10) configurées élastiquement, de sorte qu'une mise en contact du contact antagoniste (5) n'est plus garantie. Pour remédier à cet inconvénient, l'invention est caractérisée en ce que les lamelles de contact (10) sont conçues de façon que, lors d'un échauffement dans la zone de contact, la force normale de contact F soit augmentée.
