Abstract

Selon l'invention, l'élément de contact comporte un manchon qui forme intérieurement un espace de réception destiné à une languette de contact fixée au manchon et un contact mâle à insérer. Un élément expansible, dont volume dépend de la température, est disposé entre le manchon et le contact mâle. L'élément expansible a un coefficient de dilatation thermique qui entraîne une augmentation de volume lorsque l'élément de contact est chauffé. Cette augmentation du volume de l'élément expansible génère à son tour une force de pression accrue sur le contact mâle qui appuie contre la languette de contact. Cela s'oppose donc aux résistances de contact élevées, qui sont sinon à craindre, entre le contact mâle et la languette de contact. Les résistances de contact élevées conduiraient à une dissipation de puissance accrue et donc à un échauffement supplémentaire de l'élément de contact au passage du contact mâle à la languette de contact, en particulier avec des contacts à courant élevé. Ce cycle est interrompu ou affaibli par l'invention.
