摘要： A high-voltage variable resistor unit capable of permitting a circuit board to be decreased in size and preventing interruption of output thereof. A circuit board having a resistive pattern including a plurality of variable resistance elements formed on a front surface thereof is arranged in a board receiving chamber. A terminal fitment and a slide element are so arranged that a contact point between a plate-like section of the slide element and a contact section of the terminal fitment is defined in a manner to be spaced from the front surface of the circuit board toward an operation member. A fit projection of the terminal fitment is fitted in a fit hole of the insulating casing. A silicone adhesive is applied to a board supporting rib of the insulating casing to the circuit board thereto. The adhesive is constructed so as to exhibit sufficient to prevent elastic force of the arm from being reduced to a degree of causing a failure in contact between the contact section and the supported section of the slide element when it is cured.

A terminal fitment fit section of a terminal fitment mounting section of a casing is formed with a pair of terminal mounting fit grooves, in which a fitted section of a lead wire connection terminal fitment is fitted. The lead wire connection terminal fitment is made of a metal sheet of 0.7 mm in thickness by machining. A terminal section of the terminal fitment is formed into a width equal to or above a thickness of the metal sheet. The lead wire connection terminal fitment also includes a lead wire connection section, which is provided with a lead wire insertion opening which permits a core of a lead wire to be inserted therethrough and a lead wire press-fit groove in which the core of the lead wire displaced from the lead wire insertion opening is press-fitted.

摘要： A high-voltage variable resistor unit capable of firmly fixing a lead wire connection terminal formed by bending a linear conductor to a terminal fixture of an insulating casing. The terminal fixture is formed with a coupling section receiving recess for receiving a coupling section of the lead wire connection terminal therein in a manner to be in proximity to a terminal holder of a terminal fixing structure including a pair of holding elements. The coupling section of the lead wire connection terminal is pressedly fitted in the coupling section receiving recess and a held section of the terminal is interposedly held between the holding elements of the terminal holder. This effectively prevents rotation of the lead wire connection terminal about the held section, movement of the lead wire connection terminal in a longitudinal direction thereof or removal of the coupling section from the coupling section receiving recess with ease, when external force is applied to the lead wire connection section or held section of the lead wire connection terminal.

摘要： A high-voltage variable resistor includes a terminal fitment having an increased number of edge elements while being simplified in structure and down-sized. A circuit substrate which includes a circuit pattern having a plurality of electrodes and resistor elements formed thereon is received in a substrate receiving section of an insulating casing. The insulating casing is charged with insulating resin through an opening thereof to form an insulating resin layer on a rear surface of the circuit substrate. Terminal fitments are provided each of which includes a core holding section provided with three or more edge elements biting into a periphery of a core of a lead wire inserted thereinto. The edge elements each are formed between each adjacent two of three or more slits formed at a plate-like section of the terminal fitment so as to radially extend from a center thereof. The edge element, when a core of a lead wire is inserted through the edge elements into the terminal fitment, are forcibly inclined in a direction of insertion of the core, so that application of drawing force to the lead wire permits the edge elements to bite into the core. The edge elements each are formed into a triangle shape, resulting in having a pointed distal end. An increase in the number of edge elements is accomplished by increasing the number of slits.
