Abstract

Abstract An improved socket assembly is disclosed which is especially suited for use with printed circuitry. The socket is mounted on an associated printed circuit board and is adapted to receive and retain guide pins of electronic circuit modules or the like. The socket assembly further includes a non-metallic insert, such as Teflon or equivalent material, which is introduced into the socket before soldering. The insert is unaffected by the molten solder or flux and prevents entry of contaminating material into the interior of the socket during the soldering process. The insert is removable by the insertion of a module guide pin during assembly of the component mounting board.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 168 words
An improved socket assembly for receiving component guide pins, including in combination: a base formed of insulating material and having plated conductor means on at least one side thereof; a socket means mounted on said base and extending therethrough a predetermined distance, said socket means including a throughbore along the longitudinal axis with openings at respective ends thereof, said base and socket means mounted thereon being adapted for flow wave soldering treatment to permanently interconnect said socket means to said plated conductor means; resilient conductive means positioned in the socket means for applying additional pressure on an inserted guide pin, and a resilient plastic tubing insert extending through the opening of said socket means from the side of said base having said plated conductor means thereon and into a portion of the interior of the resilient conductive means, said insert being positioned in the socket means during the manufacture of said socket means, maintained therein during the soldering operation and removable by the insertion of said guide pins.
Claim 2
Dependent Claim 168 words
An improved socket assembly for receiving component guide pins, including in combination: a base formed of insulating material and having plated conductor means on at least one side thereof; a socket means mounted on said base and extending therethrough a predetermined distance, said socket means including a throughbore along the longitudinal axis with openings at respective ends thereof, said base and socket means mounted thereon being adapted for flow wave soldering treatment to permanently interconnect said socket means to said plated conductor means; resilient conductive means positioned in the socket means for applying additional pressure on an inserted guide pin, and a resilient plastic tubing insert extending through the opening of said socket means from the side of said base having said plated conductor means thereon and into a portion of the interior of the resilient conductive means, said insert being positioned in the socket means during the manufacture of said socket means, maintained therein during the soldering operation and removable by the insertion of said guide pins.
Claim 3
Dependent Claim 16 words
A socket assembly according to claim 1 wherein the insulating base is a printed circuit board.
Claim 4
Dependent Claim 17 words
A socket assembly according to claim 1 wherein the resilient conductive means is a beryllium copper spring.
Claim 5
Dependent Claim 54 words
A socket assembly according to claim 1 wherein the resilient plastic insert means is formed of a material with a low coefficient of friction and dimensioned to make a friction fit within said socket means for retention during the soldering operation while being easily removable therefrom upon the insertion of a component guide pin.
Claim 6
Dependent Claim 17 words
A socket assembly according to claim 4 wherein the plastic insert is of a synthetic resin polymer.
