ABSTRACT:
A jack socket comprises a body in which are formed an axial bore adapted to receive a phone jack, an annular groove in at least two locations spaced along the axial bore, concentric with, perpendicular to, and facing radially into the axial bore, and an access port extending radially through the body into each annular groove. A toroidal coil spring is housed in each annular groove, and includes a radially-inward facing circumference projecting into the axial bore to contact the circumference of the jack plug. An electrical connection extends through the access port to the coil spring mounted in each annular groove. A jack socket installable in a mounting hole and requiring no more access to the back of the mounting hole during installation than that provided by the mounting hole comprises a body shaped and dimensioned to be closely received by the mounting hole. An axial bore and plural radial bores are formed in the body. The axial bore extends into the body from the front face of the body and includes a plug-receiving portion adapted to receive the phone jack, and a cavity arranged in tandem with, and accessible from, the plug-receiving portion. The radial bores extend radially outwards through the body from the cavity. The jack socket also comprises mounting hole engaging elements slidably mounted in the radial bores, and an expanding element mounted in the cavity and operable via the axial bore to force the mounting hole engaging elements radially outwards into gripping engagement with the mounting hole.
