  • Patent number: 4413872
    Abstract: A preloaded electrical connector is described which comprises a housing having a mating face, a wire entry face, and cavities extending through the housing and between the faces. A contact terminal is contained in each of the cavities and each terminal has a wire connecting portion adjacent to the wire entry face. One of the housing sidewalls has an integral housing flap which is hinged to the housing between the faces. The housing flap is in an open condition so that rearward portions of the cavities are open. Each terminal has a channel-shaped wire connecting portion and has a clamping flap integral therewith which is also in an open condition. The clamping flap extends beside the housing flap and when the housing flap is moved to its closed position, it moves the clamping flap to its closed position. In use, wires are positioned in alignment with the channel-shaped connecting portions of the terminals and the housing flap is moved from its open position to its closed position.

  • Patent number: 4403821
    Abstract: A device is disclosed for effecting a line tap for modular unit, residence, or similar wiring situations. The device allows for a power cable to be tapped without utilizing a junction box, which would necessarily require severing and rejoining of the cable. The device further provides for the tapping cable to be connected to the subject power cable tap by means of known electrical connector.

  • Patent number: 4274696
    Abstract: A device is disclosed for use in a wiring system for connecting conventional components, such as duplex outlets or switches, to the system. In such a wiring system insulated conductors in jacketed cables are strung about a construction and are confined within hollow walls thereof. Access to the cables is by defined apertures in wall boards with the device making an insulation displacing engagement with the conductors of the cable. The subject devices include improved terminals and cover for use in such a device to make an improved one or two conductor interconnect as well as improved means for mounting the device on a wall board or the like, a gang mounting version, and further a one piece assembly obviating the necessity for a separate face plate to cover the device and the aperture in the wall board.

  • Patent number: 4245880
    Abstract: A convenience outlet is disclosed for use in groups or alone at any point where it is desirable to have electrical power available. The individual convenience outlet has a housing of rigid insulative material enclosing terminals which have a receptacle configuration on one end adapted to mate with a conventional plug and on the opposite end are adapted to mate with conductors. The other end of each terminal is preferably profiled to effect an insulation displacement termination of a conductor but also can be profiled to mate with a terminated conductor. The terminals also include means for grounding the outlet to a mounting box, panel, or the like.

  • Patent number: 4224486
    Abstract: A power connector includes a shunting bar which will shunt the terminals of one mating member prior to unmating of the connector and maintain the shunt condition during the initial phases of mating of the connector. This connector finds particular use where it is desirable to shunt the secondary of a current transformer when a control module is removed. Likewise the connector can be used to insure discharge of capacitance from associated circuitry thereby making them safe to handle.

  • Patent number: 4168878
    Abstract: Improved pin and socket type electrical terminals are disclosed. Each terminal includes a terminal body received in a tubular sleeve of metal having low corrosion characteristics, such as stainless steel. The tubular sleeves are secured to the respective terminal bodies by a first annular crimp intermediate the ends of the sleeves and engaging in an annular recess in the respective bodies. The socket terminal body includes a plurality of cantilevered arms which are protected against damage from overstressing by the sleeve. A second annular crimp in the socket terminal sleeve is used to set the contact arms to control the normal force applied to a mating pin terminal. An annular pad of lubricant can be positioned within the end of the socket terminal sleeve and held in position by the ends of the arms.

  • Patent number: 4155615
    Abstract: A multi-contact electrical connector is disclosed for connecting a plurality of terminal pads on an integrated circuit ceramic substrate package to a like plurality of terminal pads on a printed circuit board. The subject multi-contact electrical connector includes at least two continuous strips of contacts, each formed by a plurality of parallel spaced contact members secured between two webs of flexible insulation material and folded upon themselves. One end of each contact is secured to a pad of a printed circuit board so that the strips are free standing extending normal to the plane of the board and define the periphery of the integrated circuit ceramic substrate package received therebetween. The free ends of the contacts resiliently engage the package pads. A profiled open housing is provided to surround the upper free end of the contacts and provide a resilient backing for them.

  • Patent number: 4153326
    Abstract: A connector system is disclosed for interconnecting prewired, prefabricated modules, such as panels or housing units, with the connector system providing positive wiring and locked electrical interconnection. The subject connector system includes both hermaphroditic housings and terminals with the housings providing interlocking between mating connector members and the terminals providing ease of assembly. There are several embodiments of the connector, a first is a splice to be used for intermating cables running between modular units, a second is a panel mounting used for interconnecting a modular unit with a power distribution panel or the like, and a third is a T-connection to be used for making a line tap. The terminals include an insulation displacing slot for engagement with a conductor and the cover member of the connector is profiled to drive the conductors into the respective slotted beam portions of the associated terminals.
