Abstract

The invention relates to the field of resistance devices, and discloses an improved alloy resistor, which achieves installation and fixation of a plurality of resistor discs through mutual cooperativeuse of a U-shaped conductive sheet, a mica gasket, a porcelain piece I, a screw rod and a porcelain piece II, and solves the defects of time and labor waste due to adoption of iron sheet welding in atraditional connection mode. Europium-doped silane mica is adopted in the europium-doped silane mica modified resistor disc to facilitate dispersion of various components, improve the microstructureof the resistor discs and prolong the service life of the resistor discs under a high current. The improved alloy resistor disclosed in the invention is convenient to install, good in portability, simple to operate, low in production cost and convenient to popularize and use.

Description

technical field [0001] The invention relates to the field of resistance devices, in particular to an improved alloy resistor. Background technique [0002] The resistor is a current-limiting element. After the resistor is connected to the circuit, the resistance value of the resistor is fixed, generally two pins, which can limit the current through the branch it is connected to. Those whose resistance value cannot be changed are called fixed resistors, and those whose resistance value is variable are called potentiometers or variable resistors. An ideal resistor is linear, that is, the instantaneous current through the resistor is proportional to the instantaneous applied voltage. Variable resistors for voltage division. On the exposed resistor body, one or two movable metal contacts are pressed tightly. The position of the contacts determines the resistance between either end of the resistor body and the contacts. [0003] 201780014512.5 discloses a resistor 1 including...
