  • Patent number: 5649842
    Abstract: A terminal structure includes a male terminal which is formed by folding a piece of plate material and a female terminal into which the male terminal is inserted for an electrical connection therebetween. The male terminal has a rod-shaped electrical connection part formed on an end thereof. The electrical connection part is provided on an upper surface thereof with raised portions which are brought into contact with the female terminal when the male terminal is inserted thereinto. The female terminal is formed by folding a piece of plate material. The female terminal is provided inside thereof with a plane upper surface for depressing the male terminal and is also provided with a resilient tongue piece for supporting the male terminal from below. Due to provision of the raised portions on the male terminal, the contacting area between the male terminal and the plane upper surface of the female terminal is reduced to obtain a terminal structure requiring low insertion force.

  • Patent number: 5647758
    Abstract: An improved electrical connector assembly includes interengaging plug and receptacle connector components. One of the connector components is equipped with engagement screws, and the other connector component is equipped with screw-receiving cavities which engage the engagement screws. Each engagement screw has a guide portion in the form of a projecting guide pin fixed to its tip which projects past an endface of the one connector so as to provide a pair of alignment members which are received within the other connector cavities prior to mating of the plug and receptacle components together.With this arrangement, the exact alignment of the plug and receptacle connectors is permitted by inserting the engagement screws in the cavities prior to the mating of these connectors, thereby eliminating the possibility of interference between opposing male and female terminals of the two connector components which would cause damage to the terminals and the connector components.

  • Patent number: 5645445
    Abstract: A printed circuit board mountable connecting block of the type described in U.S. Pat. No. 4,964,812 is provided with electrical contacts which include an insulation displacement slot at one end and a circuit mountable tail at the other end. This tail may comprise a conventional solder tail, or in a preferred embodiment, may comprise a "solderless" press-fit tail. The connecting block of this invention may be mounted directly onto (e.g., through) a printed circuit board (or other electronic component). It will be appreciated that this circuit mountable feature is required and advantageous for many applications. In addition, the use of a solderless connector means (preferably a press-fit tail) is particularly advantageous for providing ease of assembly as well as lower cost (relative to conventional solderable tails).

  • Patent number: 5645439
    Abstract: An apparatus includes a connector which, in use, is connected to a shore cable. The shore cable provides power to a vehicle. A connection in the apparatus to the vehicle's starting circuit actuates an ejector mechanism when the vehicle's engine is started. The ejector mechanism ejects the shore cable from the apparatus and a switch interrupts the current prior to the completion of the ejection action, thereby preventing arcing at the connector and assuring long contact life.

  • Patent number: 5643017
    Abstract: To provide a female terminal used in an electric circuit, as well as a method of producing such a terminal, a resilient contact piece, mounted within a receptive portion for receiving a male terminal, is positively retained, thereby providing the female terminal with a high reliability. In the female terminal, a resilient contact piece is mounted within a receptive portion formed by bending an electrically-conductive metal sheet. A retaining projection and a retaining hole are provided at each of side walls of the receptive portion. With this construction, retaining ends of the resilient contact piece are engaged respectively in the retaining holes, and even if the side walls are curved by pressing forces applied during a bending operation, the retaining projections positively retain the retaining ends of the resilient contact piece.

  • Patent number: 5641302
    Abstract: An electrical connector that includes an electrical contact, a first housing adapted to receive the contact, and a second housing adapted to receive a cable. The configuration of the first and second housings and the contact are such that, during assembly of the connector, the second housing guides the cable to abut the contact in such a manner that the contact displaces an insulating layer of the cable and forms an electrical connection with a wire core of the cable. The first housing has a first gripping surface and the second housing has a second gripping surface, the gripping surfaces being arranged to face away from each other and to face perpendicularly to the longitudinal axis of the cable prior to assembly, such that the surfaces can be gripped by a thumb and forefinger and squeezed together to effect assembly.
