EP2117023A3 - Interlocking for quick connection key in electrical mechanisms - Google Patents

Abstract

It consists of an appendage -2- situated at the lower end of a quick connection key -1- and joined thereto by means of an area -4-, which confers flexibility to that area and permits the displacement of the entire appendage - 2- to get closer to the key -1- upon pressing thereupon or separating it and returning it to its starting position by ceasing to apply pressure, pressure which can be applied on the appendage -2- or on the hook -3- with which said appendage finishes at its end. The key -1- is equipped at its upper end with a hollow -8- for the insertion of the end of the wire to be connected, and is placed on a U-shaped housing -5- of the body -6- of the mechanism, so that it can swing about an axis -7- of rotation. In the swinging displacement of the key and upon approaching the external face -6a- of the body -6-, the end hook -3- of the appendage -2-, which constitutes the interlocking, comes into contact with the lower external face -9a- of a lower projection -9-, central and symmetrical, of said body -6-, sliding therealong until the aforementioned hook -3- is held back by clipping on the upper edge -9b- of the projection -9-, the key being immobilized. Once the hook -3- has been held back on the upper edge -9b- of the projection -9-, the appendage -2- being pressed, the unclipping of the hook -3- is caused given the elasticity of the material, said key freeing itself and permitting its swinging.
