  • Patent number: 5517171
    Abstract: A high-voltage electronic component including a terminal connection structure capable of connecting a lead wire to a terminal fitment without soldering. An insulating substrate having a resistance element for a variable resistor formed on a front surface thereof and a high-voltage resistor are received in a hollow insulating casing. The insulating substrate is mounted on a rear surface thereof with a terminal fitment. The terminal fitment is formed with a press-fit channel in which a lead wire is press-fitted. Upon press fitting of the lead wire, the insulating casing is formed with an opening, through which insulating resin is charged in the insulating casing to form an insulating resin layer in which the terminal fitment and lead wire are embedded.

  • Patent number: 5508678
    Abstract: A high-voltage variable resistor unit including a variable resistance circuit board and a fixed resistance circuit board, and capable of being down-sized and exhibiting satisfactory dielectric strength. A variable resistance circuit board which is provided on a front surface thereof with a variable resistance circuit pattern is received in a board receiving chamber of an insulating casing. A lid member made of an insulating resin material is arranged so as to close an opening of the board receiving chamber while keeping a front surface thereof facing a rear surface of the variable resistance circuit board. A fixed resistance circuit board is fixed on a rear surface of the lid member while keeping a rear surface thereof facing the rear surface of the lid member. A space for charging an insulating resin material therein is defined between a circuit board and the rear surface of the lid member.

  • Patent number: 5475358
    Abstract: A high-voltage variable resistor unit capable of simply and positively connecting, to a holder of a high-voltage fixed resistor used as a bleeder resistor, a wire-like terminal inserted into an electrically conductive rubber terminal provided on a side of a fly-back transformer. An insulating substrate which is formed thereon with a resistance pattern including a pair of electrodes respectively connected to first and second lead wires is received in a holder of a hollow shape made of insulating resin. The holder includes a holder body formed with an opening through which the insulating substrate is received. A wire-like terminal formed by being a rigid metal wire is heldly fitted in terminal fitting members provided on an outside of the holder. The terminal fitting members includes at least one terminal fitting member provided a wall of the holder facing the opening of the insulating casing and at least one terminal fitting member provided on one of side walls of the holder adjacent to the wall.

  • Patent number: 4499010
    Abstract: Conductive paint comprises an organic solvent having dissolved and dispersed therein a binder containing a thermosetting resin and a hydroquinone derivative which is a product resulting from reaction between a hydroquinone (polyhydric phenol) and a fatty acid having 10 to 20 carbon atoms, added to the thermosetting resin, metal powder as a conductive material, and preferably a fatty acid derived from natural oils and fats and having 10 to 20 carbon atoms. This conductive paint exhibits characteristics not inferior to those of the conventional Ag conductive paint, such as low specific resistance, high moisture resistance and high heat resistance, and is much less expensive than the conventional Ag conductive paint.
