Laminated junction box module and laminated plug-in accessory modules selectively usable therewith
First Claim
1. An electrical outlet structure adapted to have external wires connected thereto, comprisinga non-conductive generally rectangular box consisting of a back wall with side walls and end walls forming a front opening;
- laterally spaced and longitudinally extending hot, neutral and ground bus bars mounted in said box, the opposite ends of each of said bars terminating short of the respective outer surfaces of said end walls;
a one-way connector formed integrally with each of the opposite ends of said bus bars and terminating short of said outer wall surfaces, respectively;
said end walls being provided with a port individual to each connector and extending from the latter to the proximate end wall outer surface whereby the end of one of said wires may be pushed therethrough into engagement with the connector;
means carried by each of said connectors and responsive to the axial pressure of said wire ends for locking the latter against withdrawal through their respective ports, each of said hot and neutral bus bars being disposed edgewise in said box with its intermediate portion spanning said opening;
a non-conductive rectangular housing telescopically mountable in said opening;
a pair of outlet sockets mounted in said housing, one of said sockets being connectable between the end portions of said hot and neutral bars at one end of the housing and the other socket being connectable between the opposite end portions of the last-named bars, andmeans including intermediate break-out segments in said hot and neutral bars, respectively, for interrupting the flow of current through the latter bars to thereby establish independently controllable sockets.

Abstract
A unitary rectangular junction box module composed of a back rectangular base block molded from non-conductive material and having parallel bus bars laid edgewise in its front face and arranged lengthwise of its opposite side walls, the opposite ends of the bars terminating short of the outer surfaces of its end walls, in combination with a front rectangular block having a centrally disposed rectangular opening extending rearwardly therethrough, the marginal back face of the front block being laminated to the marginal borders of the front face of the back block to thereby lock the opposite ends of each bus bar between the block while leaving the intermediate bar segments accessible through said opening. The opening also may be used to telescopically receive selected unitary plug-in accessory modules for use with the junction box module.
The junction box module is further characterized by: a one-way coupler formed integrally with the opposite ends of each bus bar and adapted to grip the end of an external wire when pushed through a guide port leading from the exterior to the coupler; a release port individual to each coupler through which a pointed tool may be inserted into engagement with the coupler to release the connected wire, and by at least one of the bus bars with a break-out segment between its couplers and which may be removed, as required, to alter the circuitry of the junction box module to accommodate the circuits of the accessory modules.
