High voltage electrical components and high voltage variable resistor units and flyback transformers

摘要

Provided is a high-voltage variable linear unit capable of preventing, with a simple configuration, that a terminal is apparently turned and rotated.;A terminal portion 51 is used which has a connecting portion 51b for connecting both portions between the bulge portion 51a and the lead wire connected portion 51c. A connection portion accommodating concave portion 59 is formed in the terminal fixing portion 41 of the insulating case 1 so as to be adjacent to the terminal holding portion 53 and accommodate the connecting portion 51b of the terminal 51 therein. The connection portion housing recess 59 is filled with insulating resin and cured. A pair of wall portions opposed to the first linear connecting portion 51 1 and the second linear connecting portion 51b2 of the terminal 51 among the side portions surrounding the connecting portion accommodating concave portion 59 are provided with first and second A pair of fitting grooves 67 and 69 to which the linear connecting portions of the first and second connecting portions are fitted.
