Problems solved by technology

Therefore, the size of the housing viewed from the top view direction from the opening surface of the housing will be limited by the length of the long side of the fixed resistor substrate, making it difficult to reduce the size of the housing.
That is to say, since the size of the housing needs to be set according to the length of the long side of the fixed resistance substrate, it is difficult to miniaturize the housing, that is, it is difficult to miniaturize the high voltage variable resistor.

Abstract

A high voltage variable resistor includes a variable resistance board, a substantially rectangular flat fixed-resistance board, and a high-voltage capacitor housed in a case such that one surface thereof is open. The fixed-resistance board is arranged such that a longer side extends from the bottom surface to the opening surface of the case.

Description

technical field [0001] The present invention relates to a high voltage variable resistor for adjusting the focus voltage and screen grid voltage of television receivers and other suitable devices. Background technique [0002] A general high-voltage variable resistor includes a variable resistance substrate having a variable resistor portion, a fixed resistance substrate having a fixed resistor portion of a voltage dividing resistor mounted thereon, etc., and a case accommodating these portions . See, for example, Japanese Unexamined Patent Application Laid-Open No. Hei 11-121212. This high-voltage variable resistor is provided with an insulating casing with an opening on one side, and an "L"-shaped partition is arranged inside the casing. A first accommodating part and a second accommodating part separated by the partition are also provided; on the surface of the rectangular plate-shaped variable resistance substrate, a resistor pattern including an arc-shaped variable re...
