    • A ZIF PGA socket (20) includes a base (22) having a plurality of passageways (24) extending vertically therethrough for receiving a corresponding number of contacts (26) therein, and a cover (28) having a corresponding number of holes (30) extending therethrough in alignment with the corresponding passageways (24) in the base (22) for allowing a corresponding number of pins extending from the PGA component. A lever (44) includes a cam shaft (48) embedded within a channel (50) formed adjacent the rear region of the socket (20) wherein cover (28) includes a retention device (54) and the base includes a restriction plane (64) to cooperate with the retention device (54) of the cover (28), and both of the retention device (54) and the restriction plane (64) are disposed adjacent the cam shaft (48) for efficiently fastening the cover (28) and the base (22) together to resist the larger resistance force occurring thereabout during the socket (20) in a closed state.
    • ZIF PGA插座(20)包括具有多个通道(24)的基座(22),该多个通道垂直延伸穿过其中,用于在其中接收相应数量的触点(26),以及具有相应数量的孔(30 )与基座(22)中的对应通道(24)对准延伸,用于允许从PGA部件延伸的相应数量的销。 杠杆(44)包括嵌入在邻近插座(20)的后部区域形成的通道(50)内的凸轮轴(48),其中盖(28)包括保持装置(54),并且底座包括限制平面 64)与盖(28)的保持装置(54)配合,并且保持装置(54)和限制平面(64)两者邻近于凸轮轴(48)设置,以有效地紧固盖(28) )和基座(22)在一起以抵抗在闭合状态下在插座(20)期间在其周围发生的较大阻力。
