ABSTRACT:
Disclosed is an improved IC socket comprising a housing having terminals and an opening-and-closing mechanism to change the terminals from a contact-making position to a contact-releasing position. The housing has a platform to receive the lead wires of the IC, and a movable cover activates a swingable member which rotates. The opening-and-closing mechanism is positioned so that the swingable member tilts the opening-and-closing mechanism toward the contact-releasing position when the movable cover is depressed. The device is designed as to leave between the lead platform and a contact end a clearance C, which is smaller than the thickness T of the lead wire. Clearance C prevents any debris from sticking on the contact end, assuring the reliability of electric contacts with the lead wires of the IC. A flat cam surface on the swingable member has a variable operative slope which varies as the swingable member tilts clockwise and then counterclockwise, so that gradual and steep slopes are provided continuously as the swingable member swings about a pivot. This continuous slope variation avoids any odd feeling when the operator pushes the movable cover down.
