  • Patent number: 8210856
    Abstract: A board terminal is formed by cutting a metal wire material at a predetermined length, the metal wire material having a cross-sectional shape similar to and slightly larger than a terminal holding hole. A press-fit portion press-fitted to the terminal holding hole is pressure-forged in a direction orthogonal to an axis. Thereby, a tapered portion and a stepped edge portions are provided on both sides of the pressure-forging direction, the tapered portion tapering toward a press-fit direction, the stepped edge portion being provided to an end side of the tapered portion. Further, externally projected portions are provided to both sides of the press-fit portion in the direction orthogonal to the axis which is orthogonal to the pressure-forging direction.

  • Patent number: 7186120
    Abstract: An automotive relay and electrical connector box in which relays provided in the connector box do not include an integrated resistor, but provide for the attachment of a resistor only when a relay is connected to a circuit requiring resistance. When a common relay which does not include an internal resistor parallel-wired to the coil therein requires the connection of a resistor, both leads of a lead-type resistor are welded to terminals that project from the relay body.

  • Patent number: 7125262
    Abstract: A thin, lightweight electrical connector box utilizing fewer components due to a construction in which air, instead of insulator boards, is used as the insulating material between the ECU, other electrical components, and an internal circuit contained within the electrical connector box. Externally facing connector modules are sandwiched between a lower case and un upper case. Mounting posts are formed on each end of connector modules to fixedly secure two ends of an ECU baseboard through insertion into opposing holes formed therein. The ECU baseboard is supported by connector modules within the region between the lower case and the upper case.

  • Patent number: 7028401
    Abstract: A method is provided of connecting wires of a wiring harness to a junction box to form branch circuits. An electrical conductor material is formed in parallel strips in a Y-axis direction on one surface of an insulator board, and wires are arranged in an X-axis direction on the other side of the insulator board. A circuit assembly is formed by connecting the exposed cores of one end of the wires to the conductor material through openings provided in the insulator board. Connector terminals are installed at the other end of the wires that extend outward and away from the insulator board. Groups of wires are gathered and placed in same connectors in which joint terminals are provided. The wires are joined to the connectors to form multiple wire harnesses. The aforesaid circuit assembly is then installed within an upper and lower case assembly provided with lateral openings through which the wire harness can pass.
