ABSTRACT:
An electrical contact (10) of the hermaphrodite type is disclosed for use in a mateable electrical connector. The contact (10) comprises a tubular body (12) having a mating end (16), a wire receiving end (14) and locking means (18) adapted to secure the contact in the connector. The mating end (16) includes plural contact fingers (30) with each contact finger having a radially extending blade (38) terminating in bevelled edges (40,42). The blades (38) are spaced so that the mating end of one such contact (10) may be axially inserted into the mating end of another such contact (10') with each blade of one contact being wedgingly engaged between the adjacent blades of the other contact. The locking means (18) comprises plural shoulders (44), each shoulder of which constituting a U-shaped leaf spring being formed in the wall (20) of the tubular body (12) and each being substantially compressible in the axial direction. Means for retaining the contact in a passage of the connector includes plural platforms (58) extending into the passage, each platform defining a platform surface having a groove (64) and an abutment surface (53) opposite the platform surfaces whereby when the contact is inserted into the passage and twisted thereabout, the shoulders (44) compress between the abutment surface and the platform surfaces and into the grooves to hold the contact in place.
