Abstract
Abstract A phono-socket assembly has a stamped and drawn thin sheet metal grounding shell provided with retainer means at one end of the shell and supporting attachment bracket means on the opposite end of the shell for mounting of the assembly on a panel, and an elongate tubular contact has a phono-plug pin receiving head end portion mounted within the shell on annular insulating means with a terminal portion extending from said opposite end of the shell, retaining fingers extending from said opposite end of the shell and having retaining tips turned toward and into retaining engagement with the insulating means to retain the insulating means in assembled relation within the shell in cooperation with the retainer means and thereby maintaining the head end portion of the contact in position within the shell to receive a phono-plug pin in electrical contact in the contact head end portion. According to a preferred method of making the phono-socket assembly, the retaining fingers are formed to extend axially from the shell in clearance relation to the adjacent open end of the shell, the annular insulating means and the contact being assembled into the shell through such open end, and the fingers then being curled to turn the retaining tips toward and into retaining engagement with the annular insulating means.
