An electric component unit including a lead wire connection terminal fitment which is capable of being readily fixed on a terminal fitment mounting section of a casing and facilitating connection of a lead wire thereto is provided. 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.

Electric component unit with lead wire connection terminal fitment

A lead wire connection terminal fitment capable of permitting a plurality of lead wires to be readily press-fitted in a single lead wire press fit groove. The terminal fitment may be in the form of a relay terminal fitment, which includes a metal plate formed with a lead wire press fit groove by machining in which lead wires are press-fitted. A pair of inner surfaces of the metal plate defining the lead wire press fit groove therebetween are formed thereon with a plurality of projections and recesses engaged with an outer periphery of lead wires. The projections biting into the lead wires are so arranged that a space defined between the projections opposite to each other is reduced in width at a position thereof spaced by a distance in a depth direction of the lead wire press fit groove, resulting in being divided into a first space portion increased in width and a second space portion decreased in width.

Terminal fitment for lead wire connection and high-voltage variable resistor unit with relay terminal fitment

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.

Electric component unit with lead wire connection terminal and

A high-voltage variable resistor capable of significantly small-sizing a circuit board as compared with the prior art. A terminal fitment is provided so as to act as an electrical connector for establishing electrical connection between a slide element fixed on an operation shaft member and slid on a variable resistance pattern formed on a circuit board and an output portion thereof. The terminal fitment includes a contact holding portion which is provided at a distal end thereof with a contact portion. A contact point between the contact portion of the terminal fitment and a contact portion of the slide element is defined on a side of the operation shaft member while being spaced from a front surface of the circuit board. Such construction prevents the contact point from being defined at a central portion of the variable resistance pattern, resulting in a radius of curvature of the variable resistance pattern being reduced as compared with that in the prior art.

High-voltage variable resistor

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.

High-voltage variable resistor unit

A high-voltage variable resistor capable of significantly reducing a circuit board as compared with a prior art. Terminal fitments each are arranged so as to function as a connector for forming electrical connection between a slide element slid on each of variable resistance patterns and a terminal acting as an output section. A contact point between a contact on a contact support of the terminal fitment and a plate-like member of the slide element is positioned apart from a surface of the circuit board. The terminal fitment includes a positioner, which is positioned outside the pattern in a radial direction thereof, so that the positioner intersects the pattern while being spaced therefrom.
