摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing an electric contacter, capable of highly productively manufacturing an electric contacter having high stability in joining strength between a base metal and a contact point while suppressing the deformation of the base metal. SOLUTION: A rotating tool 22 which rotates at a predetermined speed and moves forward and backward to a jig and in which an end surface of a pushing side has a size not covering the entire surface of a contact point 3 is pushed into a position corresponding to the contact point 3 of a surface opposite to the contact point 3 of the base metal 1 while rotating the rotating tool 22, so that a joining surface between the contact point 3 and the base metal 1 is heated by a friction heat of the rotating tool 22 and the base metal 1 to joint solid phase diffusion bonding or liquid solid diffusion bonding, and then the rotating tool 22 retracts from the base metal 1, thereby manufacturing an electric contacter. As for the rotating tool 22, a pushing operation is repeatedly performed at a plurality of times while shifting the pushing position, alternatively, the position of the rotating tool 22 with respect to the base metal 1 is deviated while maintaining the pushing state when the rotating tool 22 is pushed into.

摘要： PROBLEM TO BE SOLVED: To provide an outer shell case structure for securing stable overload and phase interrupting operation characteristics by reducing thermal interference given to a heater unit in a S phase by R, T phases located adjacent to each other on both right and left sides across an interphase barrier. SOLUTION: Inside the outer shell case 14 of the thermal overload relay, heater unit chambers 14R, 14S, 14T in R, S, T phases arranged side by side across the interphase barriers 14a are defined where the heater units 1 in phases are arranged individually element by element. As a means for reducing thermal interference given to the heater unit in the S phase held between the R phase and the T phase by the R phase and the T phase, a recessed site 14d is formed outward in the outer shell case 14 so that a space of the heater unit chamber 14S in the S phase defined between the R phase and the T phase arranged side by side across the interphase barrier 14a is parted therefrom to be smaller than the heater unit chambers 14R, 14T in the R phase and T phase located adjacent to each other on both sides.

摘要： A manufacturing method of an electric contact and manufacturing equipment of the electric contact. A contact and a metal base are superimposed and support by a jig, and a rotational tool, which rotates at a predetermined speed and advances/retracts to/from the jig, is pressed into a surface, which is not contacted with the contact, of the metal base while being rotated, so that the contact and the metal base are joined by solid state diffusion welding by using frictional heat generated by friction between the rotational tool and the metal base, and then the rotational tool is retracted from the metal base.
