Abstract: A plug including a base having a top surface, a plurality of openings in the top surface, a retraction unit having a first portion in the base and a second portion extending from the base to a position in front of a corresponding opening, and a conductive unit having a notch where the conductive unit extends through one opening such that the retraction unit engages the notch to prevent the conductive unit from passing back through the opening.

Abstract: A micro-miniature electrical contact comprises a first contact portion having spaced cantilever contact leaves with distal ends adapted to mutually engage, together with outwardly bowed control longitudinal portions. When received in a mating socket the leaves are resiliently urged inwardly to effect desired receptacle engagement and electrical connection.In a preferred embodiment, the contact is formed by deep drawing a seamless, integral, generally cylindrical member in which a contact portion with leaves integrally joined at their distal ends is integrally formed with a receptacle portion adapted to engage an electrical conductor. Because of their construction, the provided contacts are adapted for repeated use without loss of resiliency.

Abstract: A multi-terminal rotary connector assembly including a plug having a generally circular mating end with contacts thereabout. A receptacle has a generally circular opening with contacts therein for receiving and mating with said plug to engage the contacts thereof. The receptacle includes an axially mounted and extending polarization and anti-separation stud for insertion into a corresponding axial aperture in the mating end of the plug. The contacts of the plug and receptacle are spaced from one another circumferentially as the plug and receptacle are mated axially, and engage one another only when the polarizing stud has been received into the axial aperture in the plug and the plug has been rotated with respect to the receptacle to its locked position. During rotation the apexes of the plug contacts slide past the apexes of the receptacle contacts to inhibit counter-rotation. Both the plug and the receptacle may include retention and strain relief means for attachment to an electrical cable.

Abstract: A circuit connector for electrically connecting a substantially flat flexible conductor to a second conductor. The connector generally includes a housing, a cover, and contacts. The housing is of insulating material and has a relatively flat conductor receiving surface and a plurality of openings that communicate with the conductor receiving surface. A generally resilient self-locking domed wiping contact is disposed in the housing beneath each opening, and slidably engages retaining grooves of the housing. At least one portion of each contact protrudes above the conductor receiving surface to make electrical contact with the flat conductor, and a second portion is adapted for connection to a second conductor. The cover is superposed the flat conductor receiving surface for receiving the flat conductor therebetween. The cover is movable to press and releasably retain the flexible circuit in electrical connection with said resilient contacts.
