Abstract

L'invention concerne un ensemble connecteur électrique à levier qui comprend un premier connecteur comprenant un boîtier diélectrique sur lequel sont montées plusieurs premières bornes. Un levier auxiliaire d'accouplement est monté pivotant sur le boîtier du premier connecteur de façon à pivoter entre une position d'accouplement préliminaire et une position d'accouplement accompli. Le levier contient un chemin de cames. Un second connecteur comprend un boîtier diélectrique sur lequel sont montées plusieurs secondes bornes destinées à s'accoupler avec les premières bornes du premier connecteur. Une protubérance de galet de came peut être engagée dans le chemin de cames du levier auxiliaire d'accouplement dans sa position d'accouplement préliminaire. Les connecteurs sont accouplés sous l'effet de la rotation accomplie par le levier pour gagner sa position d'accouplement accompli à mesure que la protubérance de galet de came parcourt le chemin de cames. Un mécanisme de verrouillage est ménagé entre le boîtier du second connecteur et le levier auxiliaire d'accouplement afin de verrouiller ce dernier dans sa position d'accouplement accompli.
