Abstract

Un nouveau connecteur d'interface permet de connecter électriquement entre eux des câbles d'entrée (15) et de sortie (11) qui se terminent par des connecteurs électriques séparables à éléments multiples de contact (12 et 16). L'interface trouve application en particulier lorsque les câbles d'entrée (15) et de sortie (11) se terminent avec des connecteurs dissemblables ou ne correspondant pas. La nouvelle interface de l'invention utilise un circuit imprimé interne (20) au lieu d'un câblage. Un connecteur électrique séparable qui possède au moins un contact électrique résilient (22') ayant une partie généralement arquée ou voûtée (54) entre ses deux extrémités (55 et 56) est également inclu. Les deux extrémités (55 et 56) de l'élément de contact (22') sont retenues contre une surface d'appui dans le logement du connecteur de sorte que le contact fonctionne comme une structure à poutre à double support. Une extrémité antérieure du contact est protégée contre les dégâts mécaniques par une enveloppe (58).
