Abstract
An electrical socket includes a molded insulative base carrying rows of resilient electrical terminals. A leadless chip carrier initially is supported on the terminals, with the pads of the carrier engaging the terminals. A lid is placed over the carrier and is rotatably advanced to press against the carrier, causing the carrier to deflect resiliently the terminals, and to seat against the base. The lid clamps the carrier against the base and is adjustable to accommodate a carrier which varies in height within specified tolerances.
Claims7
A socket for a chip carrier, comprising:
- a base,
- electrical contacts mounted on said base for engaging a circuit board,
- insulative partitions on said base separating said contacts and providing a seat for said carrier,
- projecting posts on said base having undercut inclined flanges,
- a lid for clamping said carrier against said partitions and having inclined wedge ridges on which are friction surfaces contructed to engage said flanges,
- said contacts engaging said carrier and being resiliently deflected into spaces between said partitions upon said carriers being clamped against said partitions.
