Abstract: A connector module (10,100,200) having at least one electrical terminal (24,116,206) therein, adapted to be sealingly mounted to a mounting surface upon being placed thereagainst at a connection site (30,112,204), and simultaneously form electrical connections of each terminal with a circuit (38,152,214) thereat, with the terminal adapted to be thereafter terminated to a discrete conductor wire (60,138,210,212) to interconnect the circuit with the wire. Upstanding lead members (40,160,216) are electrically connected to the circuits and are received into pin-receiving holes (50,172) along the module's bottom surface and become engaged with respective terminals. Each terminal is terminated to such a wire upon actuation of an actuator (26,118). A base section (14,104) of the module forms a seal with the mounting surface around the connection site (30,112,204). Such module can easily be mounted to a solar panel (32,110) or circuit board (202).

Protected plugs may be provided having overvoltage protection circuits, and jumper plugs may be stacked onto such protected plugs.

Abstract: A single modular assembly (10) has two terminals (18) in housing cavities (28) each with a pair of slots (38) for termination by rotary actuation to respective conductors of two cables, for crossconnecting or splicing the tip and ring lines of a customer's service line with those of a cable extending to the main distribution line. Each terminal (18) is in electrical engagement with a circuit wire (40) extending to a separate portion (20) of the module for electrical connection to an active electrode of a protector element (24). The two protector elements (24) each include a ground electrode (76) grounded to a common ground strap (54) which includes a contact section (60,64) exposed along the bottom of the module to be assuredly engaged with a ground strap (122) along the floor (112) of the enclosure (110) upon mounting of the module (10) therein, for grounding to a ground stud for external system grounding.

Abstract: An unearthed two-pin electric plug is provided. To avoid the need for tools when wiring, the plug includes a blade (2,22,62) rotating about the axis of a hinge (1) which is parallel or perpendicular to the axis of the electric lead. In the two fullest embodiment of the plug, projections cooperate to split, set up connections and connect up the lead. In one embodiment, the inner surface of the lower plug portion includes a base (80) with grooves (71,72,73) engaged by tapered splitting portions (51,52,53) which push the two conductors of the leads sideways so that they slide over the base (80) and are caught on contact spikes (5) at almost the same time as said lead is cut by the central blade (62). The lead is held in position by a filler bar (50) and by the splitting portions (51,53) which drive the lead sideways so that it winds through recesses (81,83).

A clamping arm pivotally attached to the base structure has at least one clamping finger are holding the cable in the passageway. A splicing arm with pivotable cutting means splices a significant length of wire away from the insulation and a wire pusher ensures spatial and electrical connection of the spliced wire with a receptacle. The electrical connector can splice an asymmetrical conductor cable which is also provided.

Abstract: An electrical cord end connector is provided incorporating a pair of identical relatively pivotally body members which include stepped faces lapped engaged with each other. The body members are relatively swingable between first operative positions and second inoperative positions and support a pair of electrically conductive terminals therefrom. When the body members are disposed in the second positions one pair of corresponding edges define an outwardly opening and flared recess into which one end of a two conductor extension cord or the like may be telescoped and subsequent swinging movement of the panel members from the second positions to the first positions thereof enable the panel members to (1) mechanically clamp the extension cord end thereto and (2) effect good electrical connection between each of the extension cord conductors and an associated electrically conductive terminal of the connector.

Abstract: The self-stripping electrical terminal includes a casing in which a conductive connector member in form of a U-shaped profile as well as two contact members are located which are pivotable in latter about pivot axes. The conductors which are to be mounted to the terminal can be inserted through lateral openings in the casing into the connector member.

Abstract: Relief against torque for a terminal terminated to an end portion of a flat conductor cable is provided by a low height rearward section of a metal member having opposed sections forwardly of a cable-receiving end having a transverse cable-receiving slot. The cable end is inserted through the slot for termination forwardly of the cable-receiving end and disposed between the opposed sections. The opposed sections are joined together by a pair of integral spaced bight straps or hinge sections beside the cable at the ends of the slot. The straps or hinges enable the metal member to resist torque applied to the termination by the cable. The metal member can be the terminal itself, a transition adapter for termination to flat electrical cable of the type having opposed plate sections applied to the major cable surfaces which include means for mechanical and electrical connections therewith.

Abstract: A tubular, conductive housing has an axial opening defining an inner surface. An annular, outer lip projects from the inner surface. A centrally located axle within the housing has an annular inner lip opposing the outer lip. Cylinders at either end of the housing engage the axle in the housing and have apertures therein through which wires are inserted and located between the lips. Rotating the cylinders results in the wires being stripped and making electrical contact with the outer lip and conductive housing. Thereby, the wires become electrically interconnected to the conductive housing and to each other.

Abstract: A plug for coaxial cable of the type used for wire broadcasting transmission or multiplex communication system comprising a shielding cap. The shielding cap molded from a conducting material is connected to the cable without stripping the outer insulating material because several sharp-edged sector-shaped projections formed at the end of the shield cap penetrate into the outer insulation of the cable and their tips stick in the shielding net of the cable. A socket or other contact elements of other electrical circuits may or may not have a thread for engaging the assembled plug since the shielding cap itself is made of an elastic material which allows sliding fit instead of thread engagement.

The end portion is disposed in the slot of the connector and is wedged between the opposed edges thereof for providing electrical connection therebetween. The connector has a holding unit carried thereby and having a part thereof disposed adjacent the conductor to hold the conductor in the slot by trapping the conductor between that part and the closed end of the slot.

Abstract: An instant connector has a synthetic resin housing comprising two blind ducts projecting into the housing from opposite end faces and extending in parallel to each other. A contact blade is arranged in a cavity between the blind ducts. This blade is pivotable about an axis extending in parallel to the end faces and the ends of the blade-project obliquely into the blind ducts. Upon the introduction of wires into the blind ducts, the ends of the contact blade engage these wires. By subsequently pulling the wires apart; i.e., away from each other, the ends of the contact blade burrow through the insulating sheaths of the wires into the wire cores. In this manner, the wires are electrically connected with each other by way of the contact blade.
