Title:
ASSEMBLING METHOD FOR HIGH VOLTAGE VARIABLE RESISTOR
Document Type and Number:
Japanese Patent JPH0955305
Kind Code:
A
Abstract:

To obtain a method for assembling a high voltage variable resistor in which the circuit board is prevented from floating while suppressing formation of pinhole.

In a first assembling method, an inner space 7 defined by a circuit board 1 and an insulating case 2 having a bearing part 3 for passing a rotary shaft 4 is evacuated through the bearing part 3 at the time of thermosetting an adhesive 5 for bonding the insulating case 2 and the circuit board 1. In a second assembling method, the insulating case 2 is provided with an exhaust hole and the inner space 7 defined by the circuit board 1 and insulating case 2 is evacuated through the exhaust hole at the time of setting the thermosetting adhesive 5.
