Electrical contactor and method of manufacturing electrical contactor

Abstract

To provide a method of manufacturing an electrical contactor including a volute spring structure extending in upward and downward directions formed integrally using a single material, having mechanical simplicity and excellent functionality, and functioning as an electric circuit achieving connection without loss. The present disclosure relates to a method of manufacturing an electrical contactor formed from a single rod-like conductive member of a circular cross section, the method comprising: a first step of forming a spiral slit with respect to an upper portion and/or a lower portion to be cylindrically formed of the rod-like member; a second step of winding up the upper portion and/or the lower portion of the rod-like member subjected to the slit formation performed by the first step so as to form a conical shape; and a third step of compressing a spiral structure of each hierarchy of the upper portion and/or the lower portion of the spiral rod-like member wound up by the second step until the spiral structure of each hierarchy overlaps with each other, and then performing a hardening heat treatment to form an electrical contactor including a spiral-structured elastic portion.
