  • Patent number: 6929483
    Abstract: An electrical contact (1) includes a retention portion (10) and a cantilever (12) extending upwardly from the retention portion. The cantilever includes a first extending portion (121) and a second extending portion (120) bent vertically from the first extending portion. A top elevation projection of the second extending portion relative to the retention portion forms an acute angle therebetween. The first and second extending portions are both resiliently deformable. Thus the contact attains good resilient characteristics. Moreover, a contact strip (16) for the contact comprises an elongate carrier strip (160) and a plurality of strip contacts (1?) attached to the carrier strip. Each strip contact includes a cantilever (12?) having a second extending portion (120?). The second extending portion is orientated at an acute angle relative to a longitudinal axis of the carrier strip. Thus gaps between two adjacent strip contacts are small, which reduces production costs of the contact.

The first and second extending portions are both resiliently deformable. Thus the contact attains good resilient characteristics. Moreover, a contact strip (16) for the contact comprises an elongate carrier strip (160) and a plurality of strip contacts (1′) attached to the carrier strip. Each strip contact includes a cantilever (12′) having a second extending portion (120′). The second extending portion is orientated at an acute angle relative to a longitudinal axis of the carrier strip. Thus gaps between two adjacent strip contacts are small, which reduces production costs of the contact.
