Abstract: An apparatus is disclosed for electrically connecting groups or bundles of wires to each other by means of a connector which has a plurality of displation type contacts therein arranged in parallel rows. The apparatus comprises a frame having means thereon for holding the connector and a wire guide means for locating the wires in alignment with the terminals in the connector. The wires are trimmed and inserted by means of a roller which is mounted on the frame and which is moved along a working stroke path which extends parallel to the length of the connector. The wire guide means can be selectively positioned relative to the connector to locate the wires in alignment with different groups of terminals in the connector.

Abstract: Apparatus for inserting wires into the terminals in the modules of a modular type multi-contact electrical connector comprises a frame having a base section and a head portion which is spaced from the base section. A supporting means is provided in the base section for supporting a connector module and an inserter is provided in the head section for inserting wires into terminals in the connector. The inserter comprises a sector having an arcute surface which is disposed adjacent to the connector on the base section. The sector is pivotally mounted in the head section so that it can be rotated relative to its pivotal axis. The pivotal mounting means for the sector is movable in the head section along a rectilinear path which extends parallel to the connector in the base section. When the sector is rotated about its pivotal axis and simultaneously moved along the path, the arcuate surface moves over the surface of the connector and inserts the wires into the terminals.

Abstract: Electrical junction means for cables which are part of a telephone wiring system comprises a base frame member disposed on the floor of a building. Multi-conductor cables extend across the floor and have connectors on their ends which are mounted in the base frame member. The connectors mounted in the base frame member or mated with connectors on the ends of conventional cables which extend from the junction means to telephones. Carpeting material on the floor extends up to the base frame member and flaps of carpeting are located on top of the base frame member. A cover member is secured by fasteners to the base frame member and serves to protect the connectors therein. The cover member is clamped against the carpet flaps and against portions of the carpeting which are immediately adjacent to the base frame member. This arrangement provides a self-gaging feature which reduces the tendency of the cover member to become loose.

Abstract: A hand held circuit tester for use in detecting and identifying wiring errors in standard three-wire electrical outlets. Indicator lights, connected between each pair of the three plug-type terminals, are positioned side-by-side on one end of the device. Reference characters may then be aligned with the individual lights and the condition of the wiring can readily be determined. Because of the location of the indicator lights, they may be viewed through openings on three sides permitting use of the device in awkward locations. The components used in the manufacture of the device permit easy assembly of the components into circuits and facilitate insertion of the circuits into an insulated housing to form the completed device.

Abstract: Power distribution system for building wiring comprises a flat three conductor cable which is mounted on a surface, such as a floor, and tap cables extending laterally to outlets, loads, and controls. The tap connections of the branch or tap cables are made with electrical connectors crimped onto conductors in the distribution cable and the brand cable. An improved crimp is disclosed for making these connections.

Abstract: A technique is disclosed for using a commonly available, inexpensive and rugged tool for assembling together a cover and a base portion of a wiring device of the type providing a switch, junction box or outlet receptacles, and of the type wherein wires are connected electrically in the wiring device during assembly of the cover and base portion together.
