The invention concerns an electrical contact with elastic recall comprising a contact head (2) that is fastened to the end (1') of an electrical cable (1) or similar device and is secured to the end of an elastic blade (3) whose other end, called the fastening end, is fixed in the case (6) of a device to be equipped. The contact according to the invention is noteworthy in that an area (1") of the cable (1), called the anchor area, is fastened to the said case (6) of the device, near the fastening end of the blade, and in that the cable (1) takes the form of a hook (1"') between its anchor area (1") and its end (1') equipped with the contact head (2), defining a free space in its concave curved part, while the contact head (2) presents a contact surface (2c) perpendicular to the longitudinal axis of the cable end (1') and elastic mobility essentially coaxial to the said axis, the blade (3) being fitted into the said free space and also held by a spring (11) fastened to the case (6) of the device.

L'invention concerne un contact électrique à rappel élastique comportant une tête de contact (2) qui est fixée a l'extrémité (1') d'un câble électrique (1) ou similaire et qui est assujettie à l'extrémité d'une lame (3) élastique dont l'autre extrémité, dite de fixation, est fixée dans le boîtier (6) d'un appareil à équiper. Le contact selon l'invention est notamment remarquable en ce qu'une zone (1'') du câble (1), dite d'amarrage, est fixée audit boîtier (6) de l'appareil, au voisinage de l'extrémité de fixation de la lame et en ce que le câble (1) présente une forme de crochet (1''') entre sa zone d'amarrage (1'') et son extrémité (1') munie de la tête de contact (2) en délimitant un espace libre dans sa partie courbe concave, tandis que la tête de contact (2) présente une surface de contact (2c) disposée perpendiculairement à l'axe longitudinal de l'extrémité (1') du câble et une mobilité élastique sensiblement coaxiale audit axe, la lame (3) étant aménagée dans ledit espace libre en étant en outre sollicitée par un ressort (11) fixé au boîtier (6) de l'appareil.
