  • Patent number: 5692912
    Abstract: An electrical connector includes an elongated dielectric housing having a front mating face and rear face with a plurality of terminal-receiving passageways extending therebetween. The rear face extends between opposite ends of the housing and is devoid of any substantial projections which might prevent a terminal-insertion tool from being moved into proximity with the rear face. A plurality of terminals are received in the passageways. Each terminal includes a forwardly projecting contact portion and a tail portion projecting rearwardly from the housing beyond the rear face thereof. An elongated tail aligning device is mountable on the housing and has a plurality of apertures through which the tail portions of the terminals extend. The tail aligning device has wing portions near opposite ends thereof projecting generally transversely of the rear face of the housing to protect the tail portions of the terminals and to stabilize the connector.

  • Patent number: 5203079
    Abstract: A method is disclosed for terminating a coaxial connector to a coaxial cable. The coaxial connector has an elongated signal pin surrounded in part by an insulating jacket and an elongated shield member surrounding the insulating jacket while the coaxial cable has a signal wire surrounded by an inner insulating member, ground means surrounding the insulating jacket and an outer insulating sheath surrounding the ground means. The method includes providing an elongated conductive shield member having a front portion and a rear portion. The front portion of the shield member is secured onto the insulating jacket surrounding the signal pin whereby a portion of the signal pin is positioned within the rear portion. The ground means is electrically and mechanically bonded to the rear portion of the shield member. The signal wire is then electrically and mechanically bonded to an exposed portion of the signal pin within the rear portion of the shield member while the signal pin is held by the shield member.

  • Patent number: 5186656
    Abstract: In the exemplary embodiment of the invention, the miniature coaxial contact terminates a coaxial cable which includes a signal wire, an insulating jacket surrounding the signal wire, ground means surrounding the insulating jacket and an outer insulating sheath surrounding the ground means. The contact includes a signal pin having a contact end for mating with an appropriate receptacle contact and a terminating end having a coined portion for termination to the signal wire. Insulator means is provided about at least a portion of the signal pin. A grounding shield tube is provided about the insulator means. The tube has an inner surface for termination to the ground means of the cable.

  • Patent number: 5167544
    Abstract: A female electrical contact is disclosed to include an elongate body having a terminal portion at one end and a receptacle portion at the other end for receiving a complementary male pin. A pair of cantilevered arms are provided of substantially equal length and in opposed relationship to each other with contact portions at their distal ends. The cantilevered arms are axially offset from each other in the longitudinal direction of insertion of the complementary male pin, whereby the male pin engages the contact portions sequentially. The cantilevered arms are bowed inwardly so that the contacted portion of one of the arms engages the other arm under a preload.

  • Patent number: 5131871
    Abstract: An improvement is provided in an electrical connector system which includes a connector block of insulating material having a plurality of pin receiving openings for positioning a plurality of terminal pins therein by an interference fit. At least some of the openings each are generally rectangularly shaped and include inwardly directed pin engaging projections located in diagonally opposite quadrants of the rectangular opening. The invention contemplates that the connector block may have a series of the openings in a closely spaced row. The diagonally opposite quadrants in which the projections are disposed are at the same respective locations in each opening along the row.

  • Patent number: 4060227
    Abstract: A small piece folder capable of forming both a French fold and cross fold includes a feed belt on which the unfolded articles are initially placed. Adjustable width control blades overlie the feed belt, and the margins of the article are pneumatically blown over the edges of the blades in sequence to form the French fold. The cross fold is also pneumatically initiated at the end of the feed belt.
