Abstract
Abstract Coaxial electrical connectors for printed circuit board and coaxial cable applications which are composed of a plurality of relatively low cost component parts designed to permit the connectors to be easily assembled by relatively unskilled personnel without requiring complex assembly equipment. Connectors of the invention are assembled from component parts by a method which includes the steps of encircling a center contact (23, 71, 122, 208, 305) with a dielectric base (21, 209, 306) and a dielectric insulating member (24, 72, 121, 207, 303) while engaging an outwardly projecting portion (49, 205) of the center contact (23, 71, 122, 208, 305) with the base (21, 209, 306); assembling an electrically conductive outer shell (26, 73, 102, 123, 125, 206, 302) to the base (21, 209, 306) while concentrically surrounding the center contact (23, 71, 122, 208, 305) and the dielectric insulating member (24, 72, 121, 207, 303) with the shell (26, 73, 102, 123, 125, 206, 302); and securing an electrically conductive member (22, 203) to the shell (26, 73, 102, 123, 125, 206, 302), while the conductive member (22, 203) engages and transversely overlies the base (21, 209, 306) and while the base (21, 209, 306) engages the dielectric insulating member (24, 72, 121, 207, 303). The connector family includes plug (65, 110, 300, 320) and jack (10, 100, 120, 130, 200) connectors of the threaded (100, 110, 130, 320) and quick disconnect (10, 65, 120, 200, 300) types, connectors which are adapted to be mounted to printed circuit boards (10, 65, 100, 110, 120, 130) and connectors which are adapted to terminate coaxial electrical cables (200, 300, 320). The plurality of connectors of the connector family are designed to share one or more components with other connectors in the family permitting a reduction in inventory requirements and a savings in over all manufacturing costs.
