Abstract: An electrical connector for reliably and electrically connecting a daughter board and a mother board, includes a first housing (10), a second housing (20) and a pair of board retaining means (30) wherein said second housing (20) is integrally formed with two opposed supporting portions (21, 22) which each further has a pair of spaced guiding rails (211, 221) for respectively guiding and clamping two opposed edges of the daughter board (40). A cavity portion (23, 24) is defined with a horizontal cavity (231, 241) and a vertical cavity (232, 242). Each board retaining means (30) is defined with an acting portion (31), a first resilient portion (32), a latching portion (33), a second resilient portion (34) and a retentive portion (35) for efficiently locking the inserted daughter board to maintain a reliably electrical contact between the daughter board and the electrical connector.

Abstract: A socket connector for a chip is disclosed. The socket connector for a chip comprises an insulating housing defining a mating surface and a soldering surface, including a plurality of through cavities communicating the mating surface and the soldering surface; a plurality of conductive contacts received in the through cavities, including a soldering section, a fixing section and a contacting section; and anti-wicking means including at least one attaching portion for attaching to the housing and a shielding portion for sealing up the bottom of the cavities to prevent entrance of contaminants therefrom.
