Abstract
Abstract An improved printed circuit board and socket combination for integrated circuit elements is provided. Sockets for receiving the terminal pins of integrated circuit units are mounted on a printed circuit board by a press-fit into respective openings in the board. Connections are made between selected protruding terminal pins of the sockets and either a ground or power conductive strip on the circuit board by conductive clips fitted over the selected terminal pins and soldered, or otherwise affixed to the selected conductive strips.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
189 words
In combination: a printed circuit board having printed circuits on at least one surface thereof and having at least one opening therein, and a socket element for an integrated circuit unit fitted into said opening in press-fit with the bore thereof, said socket element having at least one row of female conductors on one side for receiving the terminal pins of an integrated circuit unit, and having at least one row of elongated terminal pins on the other side thereof electrically connected to corresponding ones of said female conductors, said socket element having at least one island of resilient plastic material surrounding the row of said elongated terminal pins and displaced inwardly from the peripheral edges of said socket element, said island being received in said opening in said circuit board in press-fit with the bore thereof, said printed circuits on said printed circuit board including a first set of interconnected conductive power strips, and a second set of interconnected conductive ground strips, and further including clips fitted over selected ones of said elongated terminal pins and electrically connected selectively to said power strips and to said ground strips.
Claim 2
Dependent Claim
189 words
In combination: a printed circuit board having printed circuits on at least one surface thereof and having at least one opening therein, and a socket element for an integrated circuit unit fitted into said opening in press-fit with the bore thereof, said socket element having at least one row of female conductors on one side for receiving the terminal pins of an integrated circuit unit, and having at least one row of elongated terminal pins on the other side thereof electrically connected to corresponding ones of said female conductors, said socket element having at least one island of resilient plastic material surrounding the row of said elongated terminal pins and displaced inwardly from the peripheral edges of said socket element, said island being received in said opening in said circuit board in press-fit with the bore thereof, said printed circuits on said printed circuit board including a first set of interconnected conductive power strips, and a second set of interconnected conductive ground strips, and further including clips fitted over selected ones of said elongated terminal pins and electrically connected selectively to said power strips and to said ground strips.
Claim 3
Dependent Claim
89 words
The combination defined in claim 1, in which said socket element has two rows of said female connectors on one side thereof and two rows of said elongated terminal pins projecting from the other side thereof, and having islands of resilient plastic material surrounding each of said rows of said elongated terminal pins, each of said islands being displaced inwardly from the peripheral edges of said socket element, said islands being received in pairs of said openings in said circuit board in individual press-fit with the respective bores thereof.
Claim 4
Dependent Claim
34 words
The combination defined in claim 2, and which includes integral ribs formed on the side of each of said islands to form an interference fit between the islands and the bores of said openings.
