Abstract: When the holder 20 is assembled to the male side housing 10 (stationary side housing), the cam grooves 23a, 23b respectively engage with the cam pins 41a, 41b, so that the female side housing 40 (movable side housing) is displaced in a direction perpendicular to the assembling direction and located at the connecting position, so that both the terminal metal fittings 18, 50 are connected with each other.

The contact includes a beam portion elongated along a beam axis, and a contact mating portion flexibly connected to an end of the beam portion and defining a contact plane at an angle with the beam axis. The contact mating portion has a contact aperture therein to receive the terminal. The cover has a lead-in aperture for receiving the terminal and allowing the terminal to enter the contact aperture. The actuator is operatively coupled to the contact, for causing the contact mating portion to rotate and to engage the terminal.

Abstract: A retention module for securing a heat sink (4) to a board-mounted socket connector (2) comprises a pair of metal frames (5) and four screws (54) for securing the frames to the PCB. Each frame includes a bottom wall (50), a pair of first side walls (51) and a second side wall (52) together defining a receiving space (53) for receiving a side portion of the heat sink. The bottom wall includes an integrally formed grounding plate (50c) to contact the heat sink. The retention module further comprises a pair of clips (6) assembled to the frames thereby increasing the securing relationship between the heat sink and the frames.
