Abstract: A connector and terminal for insulated wire which includes a pin section particularly adapted to extend through an aperture in a circuit board. The connector, which is formed of a single piece of electrically conductive metal includes a tubular section adapted to receive and make electrical contact with an insulated wire, and an isolation section which is positioned between the tubular section and the pin section. The isolation section permits the pin section to be wave soldered on the other side of the circuit board without being contaminated by the insulated wire, and also protects the insulated wire from damage during soldering. The isolation section may take one of several forms, and may include a heat sink for further dissipating the heat resulting from the soldering process. Insulation displacement tynes are provided in the tubular section for making positive electrical contact with the wire.

Abstract: A coaxial cable connector for providing an electrical connection to a conductor of a coaxial cable, the conductor being surrounded by an insulating member. The connector comprises an elongated longitudinally extending sleeve member for arrangement coaxially about the insulating member. The longitudinally extending sleeve member includes a tongue member which is adapted to bend on a bending axis, which is transverse to the longitudinal direction of the sleeve member. The tongue member has a pair of spaced insulation piercing tines which are spaced apart less than the diameter of the conductor to be engaged. The pair of tines thus define a slot which is adapted to receive the conductor. In this manner, when the tongue member is bent along the transverse bending axis, the insulation piercing tines traverse the insulation and pass on opposite longitudinal sides of the conductor so that the conductor is received within the slot and engaged by the tines to make electrical contact with the conductor.

Abstract: A hollow binder for a book having removable pages such as a ledger is used for storage of threaded posts. Each of the posts are coaxial and threaded to one another. One of the posts is adapted by itself or in conjunction with other posts to be a hand tool for threading or unthreading of posts.

Abstract: A method is disclosed for manufacturing insulated electrical terminals in which the insulation is uniformly distributed over all portions of the terminal which are to be insulated. The present invention concerns a treatment of the terminal between the stages in which the terminal is initially stamped and formed and the stage in which the coating of insulation material is applied to the terminal. In this intermediate stage the terminal is subjected to a treatment which reduces any sharp edges, burrs, or the like to have radii of curvature thereby allowing the insulation coating to uniformly flow on the entire surface of the terminal.

Abstract: An installation kit for wiring systems includes flat multiconductor cable, insulation piercing connectors for electrically joining cable conductors and insulator-spacer elements, for disposition overlying a cable and insulatively spacing the connectors from the cable shield. The cable shield is in displaceable overlying relation to the cable conductors to permit installation of connectors and spacers and remains electrically connected to the cable ground conductor.

Abstract: Connecting means comprises an electrical terminal and a housing having a terminal-receiving cavity therein. The terminal is a flat one-piece sheet metal device having two integral four-bar linkage mechanisms thereon arranged symmetrically with respect to an axis extending medially through the terminal. The connecting or floating links of the linkages are adjacent to the axis, the fixed links are relatively remote from the axis, and the crank links extend diagonally between the fixed and connecting links. When a wire is positioned between the connecting links and the two four-bar linkages are deformed by applying deforming forces to the ends of the connecting links, the connecting links move laterally towards each other and clamp the wire between their opposed surfaces.

Abstract: A non-insulated printed circuit board jack includes an outer stepped drawn shell member, and a stamped contact member disposed within the shell for receiving an electrical conductor. The shell member has at one end a minor diameter portion which is freely receivable in an aperture in the printed circuit board. Intermediate its length the shell includes an integral flexible retaining portion which is generally polygonal in cross-section having alternating corner portions and side portions. The corner portions are resistively receivable in the printed circuit board aperture such that when the shell retaining portion is inserted into the aperture the inner circumference of the aperture forces the corner portions of the shell inwardly, and causes the outward expansion of the side portions, whereby the shell retaining portion tends to conform to the configuration of the printed circuit board aperture. By this arrangement, an interference or snug fit is achieved between the connector and the printed circuit board.

Abstract: The present invention relates to a wire engagement and release arrangement for electrical switches, and the like, wherein the wire engagement arrangement consists of an electrical contact which is bifurcated to form two flat spring arms, one of which is shorter than the other. A pair of individual passageways through the housing of the device to be wired are provided for receiving the bare end of an electrical wire of a pair of insulated wires which are inserted into the passageways so as to pass therethrough against the ends of the spring arms whereby the spring arms will deflect and will force the bare ends of these wires against the housing walls of the electrical device. The ends of the spring arms are provided with widened portions which allow the force on the bare ends of the wire to be applied over a larger area.
