Abstract

La présente invention concerne un contacteur motorisé comprenant un contact fixe (600) et un contact mobile (500) mobilisé par un chariot (400), ainsi qu’un moteur électrique (100) commandant le déplacement dudit contact mobile (500) de manière réversible entre une position P2 de rapprochement maximum où elle établit le contact mécanique et électrique avec ledit contact fixe (600), et une position d’ouverture P1 où lesdits contacts (500, 600) sont écartés au maximum, avec une course présentant une zone de déplacement (1) où les contacts mobile et fixe (500, 600) sont écartés, et une zone de contact (2) où une surface conductrice du contact mobile (500) est appliquée contre une surface conductrice du contact fixe (600) caractérisé en ce que ledit moteur électrique (100) entraine un mécanisme à coefficient de réduction variant en fonction de la position, avec un coefficient de réduction CI à l’interface entre une zone déplacement (1) et une zone de contact (2) desdits contacts (500, 600), ledit coefficient de réduction CI étant inférieur aux coefficients de réduction Cl1et Cl2 aux extrémités de la zone de déplacement (1) et de la zone de contact (2). Figure de l’abrégé : fig. 1The present invention relates to a motorized contactor comprising a fixed contact (600) and a movable contact (500) mobilized by a carriage (400), as well as an electric motor (100) controlling the movement of said movable contact (500) in a reversible manner between a position P2 of maximum approximation where it establishes mechanical and electrical contact with said fixed contact (600), and an opening position P1 where said contacts (500, 600) are spaced as far apart as possible, with a stroke presenting a zone of displacement (1) where the movable and fixed contacts (500, 600) are spaced apart, and a contact zone (2) where a conductive surface of the movable contact (500) is applied against a conductive surface of the fixed contact (600) characterized in that said electric motor (100) drives a mechanism with a reduction coefficient varying as a function of the position, with a reduction coefficient CI at the interface between a movement zone (1) and a contact zone (2) of said contacts ( 500, 600), said reduction coefficient CI being less than the reduction coefficients Cl1and Cl2 at the ends of the movement zone (1) and the contact zone (2).
