A compliant electrical contact assembly (11) for temporarily interfacing two electrical devices. The assembly (11) includes a contact (10) having loops (14) with axes forming with a closed coil with opposed contact points (16, 18). The axes is angled from the direction (17) of the compression force (15) holding the assembly (11) sandwiched between the electrical devices. The electrically shorted loops (14) of the coil slide on the surfaces of one another as the compression force (15) is applied, providing compliance. The contact (16, 18) can be made extremely small such that pitches in the micrometer range can be achieved with very low inductance values. The contact (10) is installed in a through aperture (24) in a dielectric panel (26) such that the contact points (16, 18)extend from opposed openings of the aperture (24). Optionally, the aperture (24) is filled with a compliant, conductive elastomer (36).

Groupe de contact électrique souple (11) pour l'interfaçage temporaire de deux dispositifs électriques. Le groupe (11) comprend un contact (10) ayant des boucles (14) avec des axes formés avec une bobine fermée avec des points de contact (16, 18). Les axes forment un angle avec la direction (17) de la force de compression (15) supportant le groupe (11) intercalé entre les dispositifs électriques. Les boucles court-circuitées (14) du coulissement de bobine sur les surfaces les unes des autres lorsque la force de compression (15) est appliquée en fournissant la souplesse. Le contact (16, 18) peut être extrêmement petit de sorte que des pas de l'ordre du micromètre peuvent être atteints avec des valeurs d'inductances très basses. Le contact (10) est installé dans un trou de traversée (24) dans un panneau électrique (26) de sorte que les points de contact (16, 18) s'étendent depuis les ouvertures opposées du trou (24). En option, le trou (24) est rempli d'un élastomère conducteur souple. (36).
