摘要:
A novel connector pair suppresses arcing during connection and disconnection. In one general aspect of the invention, first and second insulating barriers are configured to extend beyond corresponding first and second contacts, the barriers being arranged to cover a leading end of at least one of the contacts, and to engage with each other when the contacts are separated by a small gap, thereby closing off substantially all through-air arcing paths between them. In another general aspect of the invention, at least one electrical contact in a connector pair is a bimetal contact having a transitional segment made from high resistivity metal. The transitional segment is configured to make first and last contact during the initial phases of mating and un-mating, thereby increasing electrical resistance and significantly lowering the electrical current and the energy available for electrical arcing.

摘要:
An electrical connector with a cable clamp which is movably secured with respect to the connector. The cable clamp is free to pivotally move in a plane containing longitudinal axes of the cable and the terminal portion of the electrical connector, but is restrained from movement in a direction along the longitudinal axes thereof.

An indexing or keying system for electrical connectors adapted for longitudinal telescopic engagement with each other provides each connector with an indexing member having a predetermined facing configuration disposed at the connecting end thereof on one side of the centerline and a complementary indexing opening on the other side of the centerline having a facing configuration substantially identical to the facing configuration of the indexing member. By selecting unique complementary values for the facing dimensions of the indexing members and openings, the connectors may be indexed in accordance with any desired circuit parameter to prevent inadvertent joinder of dissimilar indexed connectors.
摘要:
A quick-acting electrical switch which provides a positive means for disconnecting relatively high currents in a single conductor. Circuit connection is made between two switch contacts by a reciprocally movable, spring-loaded bridging assembly. When the bridging assembly is pushed into the ''''Current ON'''' position, it is locked in position by a trigger-actuated latching mechanism. The bridging assembly will snap to the ''''Current OFF'''' position when the trigger is actuated either mechanically or by means of a solenoid. In the preferred embodiment, the latch mechanism engaging portion of the bridging assembly is free to rotate with respect to the latching mechanism to provide wear equalization. A plurality of the quick-acting switches can be stacked together with a common trigger for multiple pole requirements.
摘要:
An electrical connector in which the contacts can be safely closed and opened in the presence of a surrounding explosive or combustible atmosphere. The contacts are closed and opened within a sealed small space. The structure is strong enough to withstand the internal pressure caused by ignitable gas within the small space and provides means for the ignited gas to cool below the ignition point of the surrounding combustible atmosphere before the connector is completely separated. The connector is of novel telescoping character which substantially diminishes the longitudinal length of the connector in both open and closed condition.
摘要:
A plural-poled, genderless electrical connector having main and auxiliary contacts which telescopically engage with counterpart contacts on an identical connector. The contacts are arranged to provide a make first-break last electrical connection sequence for the main contacts and a make last-break first electrical contact sequence for the auxiliary contacts. A staggered peak insertion force load is obtained from a predetermined physical placement of the contacts within the connector.
摘要:
An adjustable mounting element for mounting a plurality of modular, interlocked electrical connectors having a pair of aligned, parallel recesses formed therein. The mounting element has a pair of adjustable, L-shaped members each having a base section and an arm section at right angles to each other. The Lshaped members are assembled together to form a rectilinear electrical connector receiving aperture with the arm section of each L-shaped member located beneath the base section of the other L-shaped member. A portion of each of the opposed, parallel arm sections is positioned within one of the electrical connector recesses to removably hold the electrical connectors. Means are provided for securing the arm sections of the L-shaped members with respect to the corresponding overlying base sections.
