Abstract: For use in a communication network, an adapter socket structure comprising a molded receptacle which has a plug hole longitudinally disposed at one end, a through-hole vertically through said plug hole at the middle and two rows of terminal slots at an opposite end on the top and bottom edges thereof; a movable jack plate movably set in said through-hole, which has an opening longitudinally aligned with said plug hole and two rows of terminal slots on the top and bottom edges thereof; and two sets of terminals respectively fastened in the rows of terminal slots on said molded receptacle and said movable jack plate, which have each a curved contact end disposed in position opposed to each other; and wherein said movable jack plate is moved downwards or upwards in said through-hole by means of the spring force from either set of terminals for connecting a plug which is inserted therein either in a normal or inverted position.

Abstract: A receptacle terminal material strip of which each terminal has integrally a front plug terminal retaining portion having a folded frame formed by bending the front end of the terminal backward with two opposite spring strips relatively obliquely projecting forward inward for holding a plug terminal and convenient for receiving electroplating process; an intermediate fastening portion having two wing projections at two opposite sides for fastening in a terminal seat in the rubber core of a receptacle; and a rear electrical connection portion having a substantially U-shaped cross section with a plurality of indentations made thereon for breaking according desired length. The terminals under processing of the receptacle terminal material strip are respectively connected with one another at two locations so that precise size can be achieved through automatic manufacturing process.
