Abstract

L'invention concerne un élément de contact à haute intensité destiné à être mis en contact électrique avec un contact complémentaire correspondant et à être relié mécaniquement à ce dernier par l'intermédiaire d'une surface de contact A de l'élément de contact à haute intensité. Les problèmes techniques existants sont résolus par le fait que la liaison mécanique est réalisée de manière auto-renforçante à mesure que la température de l'élément de contact à haute intensité augmente dans le flux de courant. L'invention concerne également une liaison électrique présentant un élément de contact à haute intensité et un contact complémentaire.
