Abstract
Abstract A contact (10) has an intermediate body portion (11) provided with respective side edges (14, 15) formed with a protruding convex portion (16) and a recessed concave portion (17), respectively. The contacts (10) are slidably inserted into respective channels (22) in the insulated housing (21) of an electrical connector (20), the channels (22) being separated by respective walls (23). When the contacts (10) are thus inserted into the channels (22), the convex portion (16) of one contact (10) cooperates with the concave portion (17) of an adjacent contact (10) to trap and deform the wall (23) therebetween, thereby exerting a resilient biasing force for retaining each contact (10) in its respective channel (22).
