Electric component unit with lead wire connection terminal fitment

A high-voltage variable resistor comprising:

• a casing made of an insulating resin material and formed on one surface thereof with an opening;
• said casing being provided on one side of said opening thereof with a terminal fitment mounting section;
• said terminal fitment mounting section being provided with at least one terminal fitment fit section in a manner to be integral with said terminal fitment mounting section;
• at least one capacitor received in said casing and including a lead wire;
• a lead wire connection terminal fitment including a fitted section fitted in said terminal fitment fit section, a lead wire connection section which is formed integrally with said fitted section and to which said lead wire extending from said capacitor is connected, and a terminal section arranged so as to extend to an outside of said casing and electrically connected to an electric component arranged outside said casing;
• said terminal fitment fit section of said terminal fitment mounting section of said casing including a pair of terminal mounting fit grooves which are formed so as to extend toward an inside of said casing from the outside thereof and in which both ends of said fitted section extending in a longitudinal direction thereof are fitted each of said terminal mounting fit grooves being closed at an end thereof facing the inside of said casing with plugs;
• said fitted section of said lead wire connection terminal fitment being provided on said both ends thereof extending in said longitudinal direction thereof with an engagement;
• said engagement being engaged with a part of said terminal fitment fit section to prevent said fitted section from being dislocated from each of said terminal mounting fit grooves when said both ends of said fitted section are fitted in said terminal mounting fit grooves toward the inside of said casing from the outside thereof;
• said fitted section is so constructed that an end thereof defined on a side of said lead wire connection section constitutes stoppers that are abutted against said plugs provided by said terminal fitment fit section to position said fitted section when said both ends of said fitted section are inserted into said terminal mounting fit grooves toward the inside of said casing from the outside thereof;
• said lead wire connection section and fitted section of said lead wire connection terminal fitment being connected to each other through a curved section so that a right angle or a nearly right angle may be defined between said lead wire connection section and said fitted section;
• said lead wire connection terminal fitment being formed by subjecting a metal sheet of 0.7 mm or more in thickness to machining;
• said terminal section of said lead wire connection terminal fitment having a dimension in a width direction thereof equal to or above a thickness of said metal sheet;
• said lead wire connection section of said lead wire connection terminal fitment being formed with a lead wire press-fit groove in which a core of said lead wire is pressedly fitted;
• said lead wire press-fit groove being formed on surfaces thereof opposite to each with ruggedness that is adapted to bite into the core of the lead wire:
• said lead wire being connected to said lead wire connection section when it is kept pressedly fitted in said lead wire press-fit groove.
