Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
90 words
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.
Claim 2
Dependent Claim
90 words
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.
Claim 3
Dependent Claim
22 words
The structure as recited in claim 1, wherein said contacts initially support said carrier away from said partitions prior to deflection thereof.
Claim 4
Dependent Claim
27 words
The structure as recited in claim 1, wherein, said friction surfaces are curved, and said lid is rotatable to wedge said curved friction surfaces against said flanges.
Claim 5
Dependent Claim
25 words
The structure as recited in claim 1, wherein, means are provided on said friction surfaces for interengaging said flanges and locking said lid in place.
Claim 6
Dependent Claim
25 words
The structure as recited in claim 1, wherein, said contacts are mounted in pockets of said base and project outwardly therefrom to engage said carrier.
Claim 7
Dependent Claim
21 words
The structure as recited in claim 1, wherein, said lid has a projecting circular flange engageable and rotatable against said carrier.
Claim 8
Dependent Claim
31 words
The structure as recited in claim 6, wherein, said friction surfaces are radially spaced outwardly of said circular flange, said lid being resiliently radially deflected when wedged against said post flanges.
