Abstract

A telephone connecting device which is capable of being mounted either within a wall to present a flush face plate in which is supported a modular jack for receiving a modular plug of a cord connected to station equipment or on an exterior surface of a wall includes a plastic receptacle which includes facilities for terminating a wall cable and for connecting the wall cable to the jack in the face plate. This permits a craftsperson during an initial visit to a home such as during construction to install a receptacle and to connect the wall cable to the terminating facilities within the receptacle. In order to have service, a customer acquires a face plate having a modular jack supported therein, connects conductors that are connected to contact elements of the jack to the terminating facilities and secures the face plate to the receptacle.

a modular jack which is mounted in said nest and which includes a cavity for receiving a modular plug that terminates the service cable and a plurality of wire-like contact elements each of which has a portion that extends into said cavity to engage a terminal of a plug that is inserted into said cavity;

cover means for enclosing said open side of said housing;

a modular jack mounted on said cover means, said modular jack including a cavity for receiving the modular plug that is connected to the station equipment and including a plurality of wire-like contact elements which are adapted to engage the terminals of the plug; and

means disposed in said housing for connecting each of said contact elements of said jack which is mounted on said cover means to said contact elements of said jack which is mounted in said nest of said housing.

4. The receptacle of claim 2, wherein said connecting means includes an index strip which is made of a dielectric material and which is connected to said housing, said index strip including an elongated base having a plurality of spaced conductor-receiving grooves formed transversely therealong, each said conductor-receiving groove communicating with a well, a first group of conductors which are received in said grooves of said index strip and which are connected to said contact elements of said jack in said nest, a connector module which is adapted to be seated in engagement with said index strip, said module including a plurality of spaced conductor-receiving grooves spaced transversely along one peripheral boundary thereof and a plurality of bifurcated beam contact elements mounted within said module with one beam of each extending into an aligned one of the conductor-receiving grooves in the module and with the other beam extending into an aligned well of the index strip to engage electrically said conductors of said first group when said connector module is mounted on said index strip, and a second group of conductors which are disposed in said grooves of said module and which are connected to said contact elements of said jack in said cover means.

6. The receptacle of claim 2, wherein said contact elements of said jack in said enclosing means are connected through conductors to a plurality of contact elements which are mounted in a carrier, said receptacle also including a jack frame which is mounted in said nest of said housing, said carrier being adapted to be secured within said frame to present said contact elements of said carrier to a cavity of said frame in said nest to engage terminals of a plug which is inserted thereinto.

7. A receptacle for enclosing electrical connections, said receptacle adapted to be mounted within a wall and adapted to interconnect the electrical connections with terminals of a modular plug, said receptacle comprising:

a housing which is made of a dielectric material, said housing having a rear wall and an open face which is opposite to and spaced from said rear wall and which is adapted to be substantially flush with an external surface of the wall;
