Abstract
Abstract The present invention relates to a connector for connecting a semi-conductor chip carrier to a printed circuit board (PCB). More particularly, the invention comprises an insulating housing and a plurality of contact-bearing spring members positioned around the periphery of a central compartment in the housing. The spring member connects the leads on the chip package to traces on the PCB.

Claim 1
Independent Claim
233 words
An electrical connector for electrically connecting a semi-conductor chip carrier or the like to a printed circuit board, comprising: a. a frame of insulating material having four sidewalls defining a central carrier-receiving compartment, each sidewall containing a plurality of conductive, contact-carrying spring members adapted to provide an electrical path between the semi-conductor chip carrier which may be positioned in the central compartment and the printed circuit board on which the frame may be mounted said frame further having a U-shaped hinge invertedly mounted at each end of one side with a first leg inserted into the frame and the second leg spaced outwardly therefrom; and b. a cover, formed from a spring material and having an opening at each end of one edge through which the second legs on the hinge may slide for hingedly mounting the cover to the frame and adapted to close over the top thereof, the cover further having an opening in the center with a plurality of L-shaped spring fingers integrally attached to and positioned around the edges of the opening such that each finger is attached to an edge and extends around a corner with the free ends being parallel to an adjacent edge, said free ends adapted to bias a carrier which may be positioned in the central compartment downwardly against the contact-carrying spring members when the cover is closed over the top of the frame.
