ABSTRACT:
A ZIF PGA socket (1) includes a base (10) and a lid (40) attached thereon. A cammed actuator (70) includes a handle (72) and a cam section (74) to move the lid (40) with regard to the base (10) in a front-to-end direction. A plurality of cavities (12) vertically extend through the base (10) for reception of the corresponding contacts (80) therein. A plurality of holes (44) extend through the lid in alignment with the corresponding cavities (12), respectively, for insertion and reception of the PGA leads (100). Each contact (80) is made of a metal plate and includes a main body (82). From the main body (82), a post (84) vertically extends downward, and a resilient beam (86) upward extends and inwardly leans to the center of the cavity (12). An engagement portion (90) is upright positioned at the top of the resilient beam (86). A curved leading surface portion (93) extends outward from one end of the engagement portion (90), which incorporates another sloping surface (125) on the fourth sidewall (124) for guiding the inserted PGA lead to move in the back-to-front direction. A recess (130) is disposed in the first sidewall (121) adjacent the top opening of the cavity (12).
