Abstract
The invention relates to a shielded connector for a motor vehicle. The connector comprises at least one casing shielding element. The shielding element includes a cable outlet portion provided with a plurality of resilient tabs that are integral with the shielding element. The tabs include a contact zone in electrical contact with a ferrule crimped to a shielding braid of a cable. The contact zone is maintained pressed against the shielding braid by means of a removable clamping ring.
Claims11
A shielded connector for a motor vehicle, comprising:
- an electrically insulating inner casing defining a cavity accommodating a contact electrically connected to an electrical cable provided with a shielding braid;
- a casing shielding element, which is electrically conductive, placed at least partially around the inner casing, said casing shielding element comprising a cable outlet portion provided with a resilient tab integrally formed with the casing shielding element, said resilient tab electrically connected to the shielding braid;
- a removable clamping ring configured to exert a radial force on the resilient tab;
- and
- an outer ferrule crimped to the shielding braid and against which the resilient tab is pressed by the clamping ring, wherein a free end of the resilient tab forms a contact zone which rests on and exerts a contact force onto an outer surface of the outer ferrule when the free end is accommodated in the cable outlet portion.
A shielded connector for a motor vehicle, comprising:
- an electrically insulating inner casing defining a cavity accommodating a contact electrically connected to an electrical cable provided with a shielding braid;
- a casing shielding element, which is electrically conductive, placed at least partially around the inner casing, said casing shielding element comprising a cable outlet portion-provided with a resilient tab integrally formed with the casing shielding element, said resilient tab electrically connected to the shielding braid;
- a removable clamping ring configured to exert a radial force on the resilient tab;
- an outer ferrule crimped to the shielding braid and against which the resilient tab is pressed by the clamping ring;
- and
- an inner ferrule placed around the shielding braid and over which the shielding braid is folded, wherein the outer ferrule comprises crimping teeth extending between the outer ferrule and the inner ferrule.
A method for assembling a shielded connector for motor vehicles, comprising the following steps:
- providing an electrical cable provided with a shielding braid;
- stripping a portion of the shielding braid in proximity of an end of the electrical cable;
- fixing a contact at the end of the electrical cable located in a vicinity of the stripped portion of the shielding braid;
- inserting the contact into an electrically insulating inner casing;
- and
- placing a casing shielding element, which is electrically conductive, on the inner casing, this casing shielding element comprising a cable outlet portion, wherein the cable outlet portion is provided with a resilient tab integral with the shielding element and extending in line with the stripped portion of the shielding braid, wherein a clamping ring is disposed above the stripped portion of the shielding braid, wherein the clamping ring is removable from the resilient tab, and wherein the resilient tab rests on an outer ferrule without any crimping operation having been performed on the casing shielding element at the cable outlet portion.
