Patent

CA 2618822

The invention relates to a cable lug (1) comprising a receiving tube section (4) for the cable (19), a flat piece-connecting section (5) that is molded on and is provided with a bore (6), and a nut (2) which is captively mounted on the flat piece-connecting section (5) and is preferably rotatably mounted. Said nut (2) does not penetrate the flat piece-connecting section (5) while being mounted by means of a shaped mounting material section (16) of the flat piece-connecting section (5), which extends into an undercut (9) that is embodied on the nut. In order to be able to rotatably mount the nut or the functional part, the mounting material section (16) is accommodated in the undercut (9) with an axial clearance. Furthermore, the mounting material section (16) is rooted in an area of the flat piece-connecting section which is lowered in a step-type manner. Said lowered area is rotationally symmetrical and is provided with a conical section which opens outward and vertically and encompasses at least one conical area. The invention also relates to a method for compression-connecting a functional part such as a nut to a cable lug as well as a nut that is suitable for this purpose.

L'invention concerne une cosse de câble (1) comprenant une section tubulaire (4) destinée à recevoir le câble (19), une section de liaison plate (5) formée contre cette section tubulaire (4) et comportant un trou (6), ainsi qu'un écrou (2) maintenu de façon imperdable, de préférence de façon rotative, sur la section de liaison plate (5), cet écrou (2) ne traversant pas la section de liaison plate (5) et étant maintenu par l'intermédiaire d'une section de matière de maintien (16) formée dans la section de liaison plate (5) et venant se loger dans un dégagement (9) ménagé dans ledit écrou (2). Selon l'invention, pour que l'écrou ou l'élément fonctionnel soit maintenu de façon rotative, la section de matière de maintien (16) est logée dans le dégagement (9) avec un jeu axial. Par ailleurs, la section de matière de maintien (16) est ancrée dans une zone de la section de liaison plate qui est diminuée de façon étagée, cette diminution présentant une symétrie de révolution et comprenant une section conique qui s'ouvre vers l'extérieur et vers le haut et qui présente au moins une surface conique. L'invention concerne en outre un procédé de connexion par serrage d'un élément fonctionnel tel qu'un écrou avec une cosse de câble, ainsi qu'un écrou adapté à cet effet.
