Two-column electrical disconnector

Abstract

A two-column electrical disconnector (10), comprising a female arm (11) and a male arm (12), provided with a contact head (13) that is adapted to enter a contact seat (14) of the female arm (11). The contact head (13) has contact recesses (15) with a substantially V-shaped profile which are open in order to receive, upon closure of the disconnector (10), contact pads (16) of the female arm (11), with contact of the type on two points (A, B). The female arm (11) comprises two half-arms (17a, 17b) that are arranged side by side so as to form between them, at a free end thereof, the contact seat (14), having thereat the contact pads (16), elastic means (18) for contrasting the divarication of the half-arms (17a, 17b) being provided, said half-arms (17a, 17b) partially divaricating, in contrast with the elastic means (18), when the contact pads (16) engage the contact recesses (15) upon closure of the disconnector (10).

Description

technical field [0001] This invention relates to a two-post electrical circuit breaker. Background technique [0002] Two-column circuit breakers with swivel arms are currently known. [0003] Such a circuit breaker has two posts at the upper ends of which are provided two arms which can be rotated in a reciprocal manner about the axes of the posts so as to be connected at their free ends. [0004] The arm of these arms having a contact head adapted to cooperate with a contact seat provided at the free end of the other arm, called the female arm, is generally called the male arm. [0005] When the circuit breaker is closed, the contact heads mate with the contact seats to create an electrical connection where they have electrical contacts. [0006] There is a need especially felt in the field of these devices to obtain effective abutment of the contacts to achieve an electrical connection. [0007] There is also a strong need to obtain a connection between these contacts ...
