Abstract: A dual gender electrical connector is made up of a "male" member, a "female" member, and a positioning means. The positioning means may be integral with either the male or female member, and/or a part of any shielding used. The male member is made up of a non-conductive support material of predetermined thickness in which electrically conductive electrical contacts are embedded in parallel. Short lengths of the electrical contacts are exposed on the rear end for connection to electrical conductors. Longer lengths of electrical contacts are exposed on the front end. The female member is made up of an electrically non-conductive support material of the basic form and often the same material as the male member, though not the same depth as the male member. Tubes having a length equal to approximately the depth of the female member support material are positioned within the support material so as to be capable of sliding over and in contact with the electrical contacts of the male member.

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.
