Title:
ALLOY RESISTOR AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/078116
Kind Code:
A1
Abstract:
Disclosed are an alloy resistor (10) and a manufacturing method therefor. The alloy resistor (10) comprises a strip-shaped resistor element (12), and electrodes (11) connected and fixed at both ends of the resistor element (12), wherein each of the electrodes (11) comprises a side wall (111) covering an end face of the resistor element (12), a top wall (112) extending inwards from an upper end of the side wall (111), and a bottom wall (113) extending inwards from a lower end of the side wall (111); and the side wall (111), the top wall (112) and the bottom wall (113) form a U shape. A U-shaped metallic material and an alloy material are used to form the electrodes (11) by means of assembling and welding, thus achieving high controllability and good product stability; the forming mode of the electrodes (11) by assembling and welding is simple, can simplify the production process of the product, improve the production efficiency and reduce the product cost; and no electroplating pollution is produced.
