Abstract
Abstract A socket assembly includes a rectangular socket body and two ejector mechanisms. The socket body has two opposed sides, a top surface, a bottom surface, a row of terminal-receiving holes formed in the top surface on at least the two opposed sides for receiving terminal pins of an integrated circuit chip therein, and a plurality of terminal pins extending from the bottom surface and corresponding to the terminal-receiving holes. Each of the ejector mechanisms includes an elongated pivot plate. Each of the pivot plates has a lower end mounted pivotally on a corresponding one of the two opposed sides of the socket body and further has a levering rib extending transversely from an inner surface thereof and extending normally above the top surface. The levering rib has a longitudinal distal edge which is formed with a row of terminal-receiving notches aligned with a corresponding one of the rows of terminal-receiving holes in the socket body.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
162 words
A socket assembly for an integrated circuit chip, said socket assembly including a rectangular socket body having two opposed sides, a top surface, a bottom surface, a row of terminal-receiving holes formed in said top surface on at least said two opposed sides for receiving terminal pins of said integrated circuit chip therein, and a plurality of terminal pins extending from said bottom surface and corresponding to said terminal-receiving holes, said socket assembly further comprising two ejector mechanisms, each of said ejector mechanisms including an elongated pivot plate, each of said pivot plates having a lower end mounted pivotally on a corresponding one of said two opposed sides of said socket body and further having a levering rib extending transversely from an inner surface thereof and extending normally above said top surface, said levering rib having a longitudinal distal edge formed with a row of terminal-receiving notches aligned with a corresponding one of said rows of terminal-receiving holes in said socket body.
Claim 2
Dependent Claim
162 words
A socket assembly for an integrated circuit chip, said socket assembly including a rectangular socket body having two opposed sides, a top surface, a bottom surface, a row of terminal-receiving holes formed in said top surface on at least said two opposed sides for receiving terminal pins of said integrated circuit chip therein, and a plurality of terminal pins extending from said bottom surface and corresponding to said terminal-receiving holes, said socket assembly further comprising two ejector mechanisms, each of said ejector mechanisms including an elongated pivot plate, each of said pivot plates having a lower end mounted pivotally on a corresponding one of said two opposed sides of said socket body and further having a levering rib extending transversely from an inner surface thereof and extending normally above said top surface, said levering rib having a longitudinal distal edge formed with a row of terminal-receiving notches aligned with a corresponding one of said rows of terminal-receiving holes in said socket body.
Claim 3
Dependent Claim
120 words
A socket assembly for an integrated circuit chip as claimed in Claim 1, wherein each of said opposed sides of said socket body has two spaced apart lug members which extend therefrom and which are formed with aligned pin holes therethrough, said lower end of each of said elongated pivot plates being disposed between said lug members on the corresponding one of said two opposed sides and having a pin passage formed longitudinally therethrough and aligned with said pin holes, each of said ejector mechanisms further including a pivot pin extending through said pin passage of said pivot plate and said aligned pin holes of said lug members on the corresponding one of said opposed sides of said socket body.
Claim 4
Dependent Claim
30 words
A socket assembly for an integrated circuit chip as claimed in Claim 2, wherein each of said elongated pivot plates has a top portion formed with a knurled inner surface.
