A self-contained or boxless electrical wiring device, such as a receptacle or switch, includes a body adapted to be mounted in an aperture in the wall of a building or a mobile home. The body houses wire grasping terminals for connection with the wires of electrical cable without requiring the stripping of insulation. Interior partitions support terminal members into which the insulated cable conductors are forced for terminating the device. The partitions are integrally formed with the front face and side walls of the body in a configuration which is readily molded. Mounting members, in the form of mounting pawls or crimp mounting members are formed at each end to permit installation near wall studs. The body is closed by a back cover having projections for driving the wires into the terminals, the cover being releasably secured via legs which engage the sidewalls.

Self-contained electrical wiring device

A separation tool has a multiple-sectioned cable-advance assembly which locates an electrical cable relative to cutting blades on an anvil assembly, portions of the advance assembly being displaced laterally to follow the positions of the cable wires during their separation. Cutters having multiple staggered edges of varying orientation relative to the cutting direction pierce the outer insulation of the cable and separate the cable wires as the cable is advanced onto the cutter blades. A uniform force is to be exerted throughout a cutting stroke by an operator of the tool. Spring loaded rods push the wires away from the cutters to free the wires at the conclusion of the separation operation.

Wire separation tool and method of preparing multiconductor cable

An electrical connector assembly for installation on a cable including a connector housing, a connector body lockably receivable in the housing, an adjustable grasping assembly for securely engaging the cable, and a collar threadably engagable on the housing for adjusting the grip on the cable. Advantageously, at least two clip members are mounted to the body and are formed with fastening portions adapted to engage receiving members in the housing for assembly of the body and housing without requiring threaded fasteners. Also advantageously, the housing is provided with a detent member adapted to project against the threads of the collar which is provided with abutment means to be abutted by the detent when reverse threading of the collar is attempted, but permit threading of the collar onto the housing in ratchet-like manner. Furthermore, the body may be formed with recesses extending radially inwardly thereof for retaining electrical contacts within the projected area of the body, and with apertures in the back of the body, providing access to the contact for an electrical conductor.
