Abstract: A locking mechanism that includes a plurality of female pins that can slide into the locking apertures of corresponding male pins, to secure a male connector to a female connector. The female pins are located within corresponding alignment apertures in the female connector and are oriented to be essentially perpendicular to the longitudinal axis of the apertures. The alignment apertures receive the male pins which have cam surfaces that engage the female pins and move the female pins from the first position to the second position. The male pins are inserted into the alignment apertures until the female pins are aligned with the locking apertures, wherein the female pins slide into the locking apertures and interlock the connectors. The female pins are connected to a handle by a chassis that can move between a first position and a second position. To disengage the connectors, the handle can be depressed to push the female pins out of the locking apertures.

Abstract: A low insertion force, high current connector terminal for vehicular applications. The terminal includes a receptacle connector member having means for varying the inside diameter of a socket thereof, and a pin connector member insertable therein. The receptacle connector member includes an outboardly displaceable resilient finger having a first stop surface engageable with a second stop surface formed on the pin connector member to prevent accidental axial displacement of the two connector members. A slot and mating guide are disposed on, respectively, the receptacle connector member and the pin connector member, said slot and guide serving as both a guide means when the members are connected and also as an indexing means to prevent the connection of two non-mating connector members.

Abstract: A modified lamp includes first and second filaments contained in an envelope to which power is selectively provided individually or conjunctively to obtain three distinct light levels. A contact member in the lamp base is modified to include a planar surface over a major portion of its radial width. Additionally, a lead wire opening that receives one of the lead wires extending from one of the filaments, is spaced from the planar surface to limit the potential for electrical contact with a tang of an associated socket. In one preferred embodiment, the lead wire opening is disposed in a recess that has a maximum circumferential dimension less than the cross-section of the tang to preclude advancement of the tang into the recess. A flat is provided along the outer periphery of the contact member to provide accurate orientation of the contact member during lamp assembly.

Abstract: Several embodiments are shown for a quick connect/disconnect microwave coaxial connector which is held together under magnetic force. In one embodiment, the ends of coaxial cables are provided with annular magnets and the end faces ground flat. A good low SWR coaxial connection is made and held by simply pushing the ends together. In another embodiment, ring magnets are employed to hold standard coaxial ends together while enabling their disconnection by pulling them apart. A magnetic adapter is used to facilitate coaxial connections.

Inclined wall surfaces are formed at both ends of a row of the contacts and are adapted to guide the leads onto vertical wall surfaces formed at lower ends of the inclined wall surfaces. To this end, the contacts at the ends of the row are guided onto the vertical wall surfaces by the inclined wall surfaces when the IC platform with the IC body supported thereon is lowered, so that the leads are brought into contact with the contacts.

Abstract: The invention relates to shielded cables and in particular to an electrically conductive junction between the conduit which shields the cable and the electrical connector at the end of the cable which serves as the cable termination. The invention comprehends an EMI/RFI adapter-ring pair each member of which surrounds the terminations of the plurality of central conductors within one of the cables to be connected and which is in electrical contact with the outer shield of the cable throughout its periphery. An annular projection on one member of the adapter-ring pair coacts with an annular cavity or groove on the other member, so that a tight fit results when the connector is pushed together. One or both sides of the cavity and projection may be of a sloping configuration.
