ABSTRACT:
The plug of a plug and receptacle connector has a hollow cylindrical shell of such internal diameter as to permit its receipt onto and over a cylindrical receptacle shell during mating. A groove formed circumferentially about the inner wall of the plug includes a pair of intertwined continuous helically wound springs secured within the groove which wipes along the external wall of the receptacle as it is fitted within the plug. One of the wire springs has a cross-sectional dimension less than that of the other. At crossover points of the springs, they are bonded to one another. When received within the internal groove of the plug part, the large diameter helically wound part of the spring means is secured to the inner wall of the groove by use of a conductive material.
