A system for locking a daughter board (100) in the header (10) of a mother board (14) without involving the daughter board connector (110). A pair of latch members (50) are disposed within latch-receiving cavities (34) of the header at each end and include latching projections that pass through notches (126) along side edges (124) of the daughter board for latching. Pivoting of the latch members (50) occurs by the daughter board (100) pushing on ejector feet (62) to pivot the latch members about cylindrical bosses (66) within cylindrical seats (36) along side walls (40) of cavities (34). Embossments (70) cooperate with detents (38,42) in cavity side walls (40) to retain the latch members in either the open or closed positions. Protruding actuating sections (58) permit latch member pivoting to unlatch from the daughter board, with ejector feet (62) initiating board removal movement.

An electrical receptacle connector assembly (4) for application to a printed circuit board consists of an insulating housing (6) and spring contacts (8) received in cavities (9) in the housing. The cavities are T-shaped having a portion that is substantially rectangular, constant cross section from a contact receiving face (12) of the housing (6) up to a position proximate to a mating face (10) of the housing and a contact retention slot (15) along one side thereof. Each spring contact (8) consists of a forward leaf contact spring (32), an intermediate retention portion (33) with retention ears (48), and a rearward contact tail (34) for soldering to a conductor on the circuit board. In each cavity (9) the retention portion (33) and a flat end portion of the leaf spring (32) lie flat against one face (24) of the cavity (9), the leaf spring being bowed towards the opposite face (26) of the cavity, with the retention ears (48) biting into surfaces of slots (15) and the contact tail (34) projecting from the contact receiving face (12) of the housing (6). The housing and the spring contacts are simple and economical to manufacture and the spring contacts are easy to load into the cavities.
