A telephone line demarcation unit separates the telephone company's property and wiring from those of the user and provides security for the telephone line connections and connectors. Compartments in the unit provide easy access for the user and further provides a selection of different types of connections or equipment that can be utilized. The telephone company terminals and test boards are separately compartmented so that the compartments can be separately sealed with seals to discourage tampering and provide evidence of tampering, and yet the user's portion of the interface box demarcation unit can be easily accessed for connecting a variety of telephone equipment.

A modular coupler is used to interconnect two modular plug-ended telephone line cords. The coupler includes a first and a second section, each having a base and side walls extending along a length. The first section includes a center wall extending in a width direction between the side walls. A plurality of slots are oriented in a lengthwise direction across the center wall. The second section includes first and second forming walls extending in a width direction and separated by an aperture of sufficient size to receive therebetween the center wall of the first section. A plurality of slots extend in a lengthwise direction across the first and second forming walls and slope inward toward the aperture. A plurality of wires are positioned within the slots of the first and second forming walls. During assembly, the center wall is moved between the first and second forming walls to bend the wires toward the first section while clamping them within the coupler. Once assembled, the first and second sections snap together and form two back-to-back hollow jacks opening out opposite ends of the coupler, each for receiving a plug or jack on the end of a line to be coupled to another line. The plugs and lines are electrically interconnected by the wires in the coupler.

Communication plug installation tool

A tool connects plugs to the ends of communication wires and in particular is used with modular type communication plugs. The tool includes two relatively pivoted handle members that are restrained in the amount that they can be separated and which include a punch that will positively force connector tangs of a plug positioned in a provided receptacle in the tool into the ends of wires of a communication cord to properly and positively connect the individual wires of the cord to the proper terminal of the plug as the handles are squeezed. The tool also has knives which can be used for stripping a specified length from the end of the outer sheath from the insulated wires before inserting the wires into a plug carried in a close fitting receptacle in one of the handle members. The punch has separated lands or bars that separately bear against each contact tang of the plug and in this way force the connecting tang into the individual communication wires.

A communication cover plate and jack assembly includes a cover plate and a jack body removably attached to the cover plate. The cover plate has a pair of parallel resilient wall portions extending outwardly therefrom with each cover plate wall portion having an integral lug. The jack body has a pair of parallel jack body sidewall portions each having integral ridges extending outwardly therefrom. The sidewall portions of the jack body fit between the wall portions of the cover plate with the lugs and the ridges being in interfering relationship with each other securely holding the jack body and the cover plate together.

A wall plate is used for both a receptacle for a remote conventional telephone and for mounting a wall telephone by either detaching or attaching a pair of mounting posts. The wall plate is fastened to a support, such as a wall, and has a communication receptacle or jack located therein. A pair of plugs cover a pair of spaced-apart apertures in the wall plate when the wall plate is used with remote conventional telephones. To mount a wall telephone on the wall plate, the plugs are removed and detachable mounting posts are placed through the apertures and secured to a backing frame. The wall phone is mounted on the mounting posts and connected to the jack.

A connector device, for use in a communication system, that receives an electrical communication plug is mounted on a surface such as a wall. The device includes a cover plate having at least one opening and a periphery on a rear side that is mounted flush with screws against the wall. At least one receptacle is attached adjacently to the rear side of the cover plate and has an insulated housing with a communication plug receiving end. The plug receiving end is aligned with the opening and is substantially in the same plane as the cover plate for receiving the plug. A rear end of the receptacle extends into a cavity in the wall. The plug receiving end includes a plurality of spaced apart conductive spring-type contacts, each conductive spring-type contact conductively contacts a corresponding electrical conductor within the plug when the plug is inserted into the plug receiving end. A plurality of wires extend from the rear end of the receptacle and are conductively connected to the spring-type contacts. A terminal board is positioned on the rear side of the cover plate and has a plurality of conductive terminals on a base which are conductively connected to the wires extending from the rearward end of the receptacle and to a plurality of wires conductively connected to the communication system. The terminal board has a plurality of supports projecting towards the cover plate spatially supporting the base from the rear side of the cover plate.

A multiple cable connector box conductively connects a plurality of multi-conductor cables. Each cable has a first multi-contact connector which is conductively connectable to a second multi-contact connector supported within the multiple cable connector box. The box or housing has a plurality of openings with each multi-conductor cable extending through one of the openings. A plurality of flexible retaining posts can hold each second multi-contact connector within the box in at least two positions such that each cable can extend into the box through at least one of two different openings by changing the second connector's position within the box. Each opening not having one of the cables extending therethrough is closed off with a cover.
