Abstract

Cette invention concerne un connecteur de réceptacle comprenant un mécanisme anti-rotation servant à empêcher une tige de rotation de tourner lorsqu'un cône d'emboîtement supérieur se trouve en position emboîtée, lequel connecteur peut toutefois fonctionner normalement et sans heurt. Une tige de rotation (6) est introduite dans un orifice d'introduction de tige (5) formé dans le corps (1) principal du connecteur, et des cônes d'emboîtement (7a, 7b) sont placés sur les extrémités supérieure et inférieure de la tige de rotation (6). Un orifice d'introduction de butoir (31) est formé dans le corps (1) principal du connecteur de telle sorte que l'orifice traverse verticalement une bride (2) et communique avec une chambre (4) creuse se trouvant dans le corps (1) principal du connecteur. Un butoir (32) est placé dans l'orifice d'introduction de butoir (31). Une protubérance (33) est placée sur la périphérie externe de la tige de rotation (6) de sorte qu'elle se trouve face au butoir (32) en direction circonférentielle de la tige de rotation (6) dans une position permettant au butoir (32) d'être abaissé et bloqué. Le butoir (32) est de forme sphérique lui permettant de se déplacer sans heurt dans l'orifice d'introduction de butoir (31) et permettant également au mécanisme anti-rotation de la tige de rotation comprenant le butoir (32) et la protubérance (33) de toujours fonctionner sans heurt.
