  • Patent number: 5653615
    Abstract: An object of the invention is to quickly supply inexpensive large current terminals without entailing complicated metal-working process and labor. Further, another object thereof is to provide methods of metal-working such terminals. A large current male terminal is constructed by forming a hollow cylindrical electric contact part on one end of a conductive pipe, a hollow cylindrical wire crimping part on the other end thereof, and a collar between the electric contact part and the wire crimping part. The electric contact part has a substantially conical nose and is formed by squeezing one end of the conductive pipe in such a manner that the diameter of the one end is gradually reduced frontward. The wire crimping part has such an inner diameter as to allow a wire to be inserted thereinto. The collar has a diameter larger than the other parts.

  • Patent number: 5498176
    Abstract: The present invention provides a system which can easily connect a shielding wire and a terminal in a shielding connector without damaging an internal sheath of the shielding wire and causing contact between a shielding layer and core wires of the shielding wire. The system has a shielding layer pressing member having an inner diameter substantially the same as the outer diameter of the internal sheath of the shielding wire, and shielding tube 7. The shielding layer pressing member is fitted to the terminal of the shielding layer exposed by stripping a terminal portion of the external sheath of the shielding wire, and is slid toward the remaining portion of the external sheath to contract the shielding layer. The shielding tube is inserted between the internal sheath and the external sheath with the contracted portion of the shielding layer therebetween and is fixed by caulking from the outside thereof.

  • Patent number: 5498111
    Abstract: The present invention is a method of manufacturing a screw connector by an injection metal mold. The screw connector includes a connector main body and a nut embedded in the connector main body. An axis of the nut extends in a forward and backward direction of the connector main body. The screw connector further includes a first opening located on a front side of the nut to be inserted by a bolt of a mating connector and a first columnar space located on a rear side of the nut to receive a distal end portion of the bolt. The method includes the three steps. The first step is setting said metal mold in such a state that said nut is held by a front projection portion and a rear projection portion. This front projection portion projects rearwardly and having a small diameter portion and a portion having larger diameter than said small diameter portion. This rear projection portion projects forwardly to be in contact with a rear end face of said nut. The second step is injecting a melted resin in said metal mold.

  • Patent number: 5476392
    Abstract: In a connector device, a female connector is fixedly mounted on a first base body, and a male connector 10 is mounted on a second base body which is swingable about a rotating axis with respect to the first base body, in such a manner that the male connector is loosely fitted in a guide, being displaceable in a direction perpendicular to the rotating axis, and is kept urged towards the rotating axis by urging means. Hence, the guide member of the male connector is engaged with a guide hole of the female connector while abutting against the wall surface, on the side of the rotating shaft, of the guide hole, which makes it possible to decrease the dimension L1 of the guide hole in the direction perpendicular to the rotating axis. That is, the connector device can be miniaturized.
