Abstract

L'invention concerne un cadre de retenue (1) pour un connecteur électrique, destiné à recevoir plusieurs inserts de contact (2), présentant un cadre de base (3) qui présente deux parois latérales (4, 4') en vis-à-vis et deux parois frontales (5, 5') également en vis-à-vis, les deux parois frontales (5, 5') étant disposées perpendiculairement aux parois latérales (4, 4'), au moins deux bras à ressort (6, 6') élastiques étant disposés au niveau des deux parois latérales (4, 4'), une zone de réception (8, 8') pour une saillie d'encliquetage (9, 9') d'un insert de contact (2) étant formée dans lesdits bras et une section de bride (10, 10'), présentant au moins un contact métallique de connexion (11), étant disposée au niveau d'au moins une paroi frontale (5, 5'). Le cadre de retenue selon l'invention peut être fabriqué de manière particulièrement simple en ce que le cadre de base (3) est constitué d'un matériau électriquement faiblement ou non conducteur et est fabriqué par moulage par injection. Le cadre de retenue (1) permet également une mise à la terre, en ce qu'une cavité (12) est formée dans au moins une paroi latérale (4, 4') et une cavité (13) est également formée dans au moins une paroi frontale (5, 5'), les cavités (12, 13) étant reliées l'une à l'autre, et en ce qu'au moins un élément de liaison métallique (14) est disposé dans les cavités (12, 13), les cavités (12, 13) étant disposées et ledit au moins un élément de liaison métallique (14) étant conçu de manière telle qu'une connexion électriquement conductrice existe via l'élément de liaison (14) entre au moins une zone support (15) au niveau du bord libre (16), supérieur dans le sens d'introduction E d'un insert de contact (2), d'au moins une paroi latérale (4, 4') et ledit au moins un contact métallique de connexion (11) de la section de bride (10, 10').
