Abstract
An improved lead socket insert assembled into a contact member which is adapted to pluggably receive a lead of a circuit component, such as an integrated circuit package is provided. The insert has a hollow cylindrical body portion and fingers that are bent at a fulcrum position so that they converge. The insert has improved operational characteristics which engage a component lead with greatly reduced mating forces due to a weakening at the fulcrum position. The lead socket insert allows for higher density application of electronic packages when assembled into loose contact members or directly mounted into an interconnection panel.
Claims18
A lead socket insert comprising a collar and a plurality of fingers, each finger having a first and a second end, each said finger being joined to said collar at said first end, and each of said fingers being bent at a fulcrum position toward each other so that said fingers converge and are disposed in registry with each other to permit the fingers to converge about a lead that is inserted therebetween, said first end at said fulcrum position where said fingers are bent toward each other being structurally weakened to reduce the flexible strength of each finger so that the friction force of said fingers is reduced when a lead is inserted therein.
A lead socket insert comprising a cylindrical collar and four fingers, each finger having a first and a second end, each said finger being joined to said collar at said first end, and each of said fingers being bent at a fulcrum position toward each other so that said fingers converge and are disposed in registry with each other to permit the fingers to converge about a lead that is inserted therebetween, each said finger increased in width from said fulcrum position along a lengthwise portion thereof and having an undercut disposed at the fulcrum position to reduce the flexible strength of each finger so that the friction force of said fingers is reduced when a lead is inserted therein.
