  • Publication number: 20040147176
    Abstract: An electrical clip connector has a terminal clip which is electrically mated to a ground stud by hand. The terminal clip is protected by an erogonomically friendly housing which supports the functional requirements of the terminal clip. The housing has a hoop portion which defines a through hole orientated concentrically to a bore defined by a resilient barrel segment of the terminal clip. Communicating transversely with the rough hole is a channel carried by a first portion of the housing which encases a first arm of the terminal clip engaged to a circumferential first end of the barrel segment. A second or activation arm of the terminal clip extends from an opposite end of the barrel segment and crosses over the first arm so that compression of the arms toward one-another causes the loop segment to enlarge for receipt of the ground stud. The second arm is encased by a second portion of the housing which is preferably hinged to the first portion near the hoop portion.

  • Patent number: 6547605
    Abstract: An electrical connector uses a single flex circuit having two banks of electrical conductors each engaged to a series of terminals disposed or engaged in first and second carriers. The carriers are stacked upon one another and then inserted into a shroud of the electrical connector from a lateral direction. A clip retainer is then inserted from the rear into the shroud of the electrical connector between the first and second carriers to assure the position of the individual terminals within the respective carriers. The single flex circuit is replaced by a plurality of individual electrically insulated conductors in a second embodiment.

  • Patent number: 6358104
    Abstract: Disclosed herein is an electrical female terminal which comprises a direct current path between a contact region defined by a plurality of circumferentially spaced contact vanes formed as beams having opposite ends connected to terminal body portions and wherein each vane is twisted on its length to provide a radially inwardly directed contact on a beam that provides a torsional force component that increases normal forces for providing electrical contact without producing a commensurate increase in the force required to engage a pin within the contact region.

  • Patent number: 6232556
    Abstract: An electrical connector forms a permanent electrical connection between a flat cable having multiple conductors and a plurality of round wires. The connector comprises a first connector half and a second connector half. The first connector half has a flat cable channel and at least one flat cable access window in communication with the flat cable channel. The second connector half has a plurality of wire channels for receiving round wires, and at least one wire access window in communication with one of the wire channels. Each cable access window is aligned with at least one wire access window to facilitate a permanent connection between a conducting strip of the multiple conductor flat cable and a conducting core of the round wire.

  • Patent number: 6152787
    Abstract: A miniaturized female electrical terminal (100) having single piece construction which provides positive locking in a sealed system type connector and ability to visually inspect for manufacturing defects, even wherein the outer barrel diameter is less than 1.80 millimeters. The female electrical terminal includes a terminal portion (102), a cable connection portion (104) and an intermediate neck (106) located therebetween. The terminal portion includes an inner barrel (108) which is concentrically located within an outer barrel (110) and connected thereto by a strap (116). A forward end portion of the inner barrel is composed of a first terminal arm (112), a second terminal arm (114) and a portion of the strap, which are annularly arranged to provide a three-point female terminal contact (118). The cable connection portion includes a pair of wire crimp wings (120), a pair of insulation jacket crimp wings (122) at an enlarged diameter area (124), and a neck transition area (126).

  • Patent number: 4722691
    Abstract: An improved header assembly includes means providing for improved conductor pin flexibility to accommodate forced shifting caused by support manufacturing tolerance variations or by differentials in rates of thermal expansion. A comb member is formed of a flexible material having a sufficient rigidity to retain the conductor pins in the proper position to be joined by solder joints to an array of holes in a circuit board, but is sufficiently elastic to allow the pins to shift later so as to not jeopardize the solder joints.

  • Patent number: 4572878
    Abstract: Battery temperature sensing device including a sensor embedded in a housing and together secured to the underside of a battery cable terminal for pressing against the side wall of the battery beneath the electrolyte level therein when the terminal is coupled to the battery. The housing conforms to the underside of the terminal and is detachably secured to the terminal by means of a cap which conforms to the topside of the terminal and is adjoined to the housing via snap-in fasteners.

  • Patent number: 4346959
    Abstract: An electrical connector comprises a plurality of female terminals which are attached to conductor wires which are passed through the longitudinal assembly slots of a connector body after which the female terminals are pulled into the terminal cavities of the connector body through contact openings at one end of the connector body. The female terminals have projecting tabs disposed in the longitudinal assembly slots to orient the female terminals in the terminal cavities and latch fingers to retain the female terminals in the terminal cavities. The latch fingers are accessible through the longitudinal slots to release them from cooperating latch shoulders in the terminal cavities so that the female terminals may be individually removed from the terminal cavities through the contact openings.
