Title:
MANUFACTURING METHOD FOR SHUNT RESISTOR
Document Type and Number:
WIPO Patent Application WO/2017/110354
Kind Code:
A1
Abstract:
In the manufacturing method for a shunt resistor according to the present invention, it is assumed that at least one of first and second conductors has a thickness larger than that of a resistance alloy plate material and that the conductor having the larger thickness has: a junction surface which is joined, in a state where the edge thereof on one side in the plate thickness direction is positioned to a junction surface of the resistance alloy plate material, to the junction surface of the resistance alloy plate material; a first inclined surface the position of which becomes closer to the one side in the plate thickness direction, from the edge of the joint surface on the one side in the plate thickness direction toward the side opposite to the resistance alloy plate material with respect to the plate surface direction; and a first plate surface extending from the edge of the first inclined surface on the one side in the plate thickness direction, to the side opposite to the resistance alloy plate material with respect to the plate surface direction. The method comprises welding together the joint surfaces of the resistance alloy plate material and the conductor having the larger thickness by irradiating both the joint surfaces with an electron beam or a laser from the one side in the plate thickness direction.
