  • Patent number: 5000695
    Abstract: A female connector to be used in combination with a male connector to make electrical connection in a high voltage circuit. The female connector has a cylindrical case made of insulating material. A holder made of elastic material is inserted into the case and fixed therein. The holder is formed with a cavity which is open at one end, and a female terminal is disposed in this cavity. The female terminal has a plurality of spring strips at one end adapted to elastically hold a male terminal, and a leader portion at the other end. The leader portion is exposed beyond the end of the holder opposite to the open end. The leader portion has a lead wire connected thereto, the lead wire being led out of the case. The open end out of which the lead wire is led is sealed by a sealing member made of insulating resin.

  • Patent number: 4866566
    Abstract: A capacitor network mounted to an input-output unit of a computer for eliminating noises, which disposes on one surface of a dielectric substrate a plurality of electrodes and on the other surface of the same at least one common electrode opposite to the plurality of electrodes so that lead terminals connected to each of the plurality of electrodes and earth terminals connected to the common electrode are formed of metal strip.A pair of terminal blocks formed of the metal strip are inserted onto the dielectric substrate from both lateral sides thereof so as to hold the dielectric substrate between the lead terminals and the earth terminals, each terminal being fixed to the respective electrode, and thereafter the metal strip is cut off, thereby forming a three-terminal capacitor leading out the terminal from each electrode.

  • Patent number: 4855866
    Abstract: A capacitor network is provided for noise elimination on the input/output terminals of an electric computer or the like. A plurality of data electrodes are disposed on one surface of a dielectric substrate, and a common electrode is disposed opposite to the data electrodes on the other surface of the dielectric substrate. A pair of lead terminals are connected to each data electrode at both ends of the electrode, and at least one ground terminal is mounted to the common electrode, thereby forming a plurality of three-terminal capacitors in network.
