Zero insertion force socket having improved actuator position

摘要

a ZIF (Zero Insertion Force) socket ( 1 ) for electrically connecting a chip module with a printed circuit board ( 9 ) comprises a bottom stationary base ( 11 ) comprising a base portion ( 114 ) and an accommodating portion ( 113 ) at one side of the base portion, a top movable cover ( 12 ) slidrably assembled to the base and comprising a body portion ( 121 ) defining a plurality of through slots ( 1220 ) aligning with contact-receiving slots ( 1120 ) and a head portion ( 122 ) covering the accommodating portion, and an actuator ( 15 ) assembled to the base and the cover and is capable of being actuated to drive the cover to slide between open and closed positions relative to the base. The accommodating portion defines a base receiving cavity ( 1130 ) therethrough. The head portion defines a cover receiving cavity ( 1220 ) therethrough. The actuator comprises a bottommost operating section ( 151 ) rotatably received in the base receiving cavity and accessible from outside, and a mounting section ( 153 ) received in the cover receiving cavity.
