Abstract: An electric connector comprises a housing arranged to receive a number of contact members arranged to be inserted and removed from one end of the housing. Each contact member is located in an aperture defining a retaining shoulder, a contact-locating portion, and a slot communicating with and parallel to the aperture. Each contact member has a terminal portion, a contact portion, and a retaining portion, the latter arranged to extend into the slot and prevent withdrawal of the contact member by becoming wedged across the aperture.

Abstract: An electric connector comprises a housing (10) having a base (11) and two side walls (12, 13) together defining a longitudinal slot (14) into which a plug member may be inserted. A plurality of projecting walls (15) define a number of transverse openings (16) extending from the longitudinal slot (14), and each of these openings contains an electrically-conducting contact member (17). Each contact member has a terminal portion (18) extending out of the base (11) of the housing (10), a contact portion (19) which may extend into the longitudinal slot (14) and an actuating portion (20).The contact members (17) may be retracted out of the longitudinal slot (14) by an actuating tool comprising a pair of arms (25) which engage with the side walls (12, 13) and, when moved in a direction parallel to the longitudinal slot (14) engage with the actuating portions (20) of all the contact members (17). The front edges of each arm (25) is provided with a ramp (26) to provide gradual engagement.

Abstract: An electric connector for interconnecting two printed circuit boards comprises a socket member for attachment to one board and a plug member for attachment to the other board. The socket member contains a number of rows of rigid contact members, while the corresponding contact members in the plug member are resilient. The resilient members are arranged so that they all deflect in the same direction when the plug is inserted into or removed from the socket.
