Abstract: Disclosed herein is a connector which comprises a female housing and a male housing to be inserted and fitted into the female housing for establishing electrical connection therebetween. A flexible locking arm having a locking aperture is provided on either the male or female housing, and a locking projection is provided on the other housing for generating a restoring force in the locking arm by cambering the locking arm when the male housing is inserted into the female housing. The locking projection engages with the locking aperture by the restoring force in the locking arm when the male and female housings are properly fitted together. The connector further comprises a member provided on the locking arm for producing a fitting-confirmation sound by the restoring force in the locking arm when the locking projection becomes engaged with the locking aperture.

Abstract: Disclosed is an electrical card guide or edge connector for mechanically and electrically connecting two printed circuit boards.

Abstract: An insertion/extraction mechanism is used to cause blind mateable electrical connectors on an electrical module to engage and disengage mating electrical connectors in a housing by forcing the module to and from its fully inserted position within the housing. The mechanism includes a U-shaped handle pivotally mounted to the module at its ends through elastomeric sleeves. The sleeves are each mounted in a mounting hole in the module and each has a central bore within which a mounting shaft, extending from the handle, is housed. Each end of the handle has a camming surface which engages a pivot pin carried by the housing as the handle is pivoted while inserting the module into and withdrawing the module from the housing. This engagement of the camming surfaces and the pivot pins causes the handle ends and the associated mounting shafts to push radially against the elastomeric sleeves as the handle is pivoted during insertion and extraction.

Pressure is applied between the members to establish a pressure connection between the conductors of the cable and the respective conductor tracks by means of latches forming part of the backing member and engaging surfaces at the ends of a member fixed to the second member.

Abstract: To provide for rapid manufacture and ease of assembly, the coaxial connector is formed by an inner center terminal element having a central prong and two clamping elements projecting radially therefrom, the one closest to the prong being clamped over the center conductor (16) of the connecting cable and a further one being clamped or crimped over the insulating jacket of the coaxial cable to be connected, to provide for strain relief.

Abstract: An electrical connection device for electrically operated components of heaters, especially vehicle heaters, in which block-shaped plug parts are molded on the lines coming from the components. The block-shaped plug parts are grouped side-by-side into a unit and a cap is attached to this unit. The cap has connection parts which are designed to be complementary to connection parts of the block-shaped plug parts so that a plug-in electrical connection is formed when the cap is mounted to the unit. Accoding to a preferred embodiment, the block-shaped plug parts are placed directly on the outside of a housing of a heater and they are connected with each other to form the unit with the help of interlocking connections and the cap. In another embodiment, the block-shaped plug parts are grouped into a unit and held together by a support having a pocket for each block-shaped plug part which is fastened to the heater by a holder.

Abstract: A conducting terminal of a telephone cord plug, which has two claws with a pair of opposite inclined surfaces capable of closely clamping the inner copper wire of the telephone cord jack for current-conduction with minimum damage to the copper wire when inserted into the telephone cord jack, is disclosed. A middle projecting tang or member is also provided between the above two claws so as to only pierce through the outer cover of the telephone cord for enhancing the association of the conducting terminal with the telephone cord jack. A plurality of projecting detents are also defined upon the conducting terminal so as to engage the guide plates of the jack, thereby preventing seperation of the conducting terminal from the jack.

Abstract: A plug-receptacle type electrical connector in combination with a thin, cular, elastomeric membrane joining a plurality of cylindrical elastomeric embossments formed as an integral part thereof. Each embossment further has conical ends at each extremity and an outside diameter slightly larger than the receptacle socket cavity it will contact. Each embossment also has a longitudinal through-hole of inside diameter (ID) slightly smaller than the electrical connector plug pin it is intended to fit over. The membrane is coated with a dielectric grease and slipped over the plug pins. Connector clamping forces produce hydrostatic forces, first on each embossment which causes water remaining between the pin and the embossment ID and then pin-to-pin to be broken into a discontinuous series of microspheres. The resulting discontinuity produces full electrical isolation for the assembled pins and sockets and pin-to-pin for the mated connector. Total refurbishment of a connector may thus be accomplished in situ.

Abstract: An insulation displacement connector with a dielectric body having terminal members extending through the body, the terminal members having insulation displacement terminals at one end and outwardly projecting terminal pins at the other end. In preferred structures, the terminal pins are displaced from the terminal members so that they lie in two rows which are spaced-apart laterally of a plane of the body. The body may be a single molded structure with location positions for the terminal members inserted into one side of the body.

Abstract: A high contact force, high elastic response range pin-receiving electrical contact is provided in a pin-receiving contact including a base portion and a pair of spaced apart cantilever beams which extend forwardly from the base to a pin-receiving end. A pair of inwardly directed contact surfaces are defined on each cantilever beam facing the opposed beam for slideably, electrically engaging an inserted pin terminal. In accordance with the invention, a resilient beam support member extends from and interconnects the pin-receiving ends of the cantilevered beams. The resilient beam support member provides a significantly improvement in the elastic response range of the pin-receiving contact by enabling each cantilevered beam to endure a greater outward displacement before a minimum yield in the beam occurs while providing a greater normal force against the pin.

Abstract: An electrical connector comprises a plug having an elongate prong releasably received in a hollow receptacle and retained for electrical contact by a retainer. An improvement of that electrical contact is achieved by tensioning the prong in the receptacle against the retainer. A spring may be tensioned for that purpose in the receptacle between that receptacle and the prong.
