Claims (1)

[Claims for Utility Model Registration] (1) Fixation in which a pair of extended terminals are press-fitted and fixed via a leaf spring into opposing grooves of a pole partition wall of an insulating case, which is a pair of extended terminals arranged oppositely with a gap between them. a contactor, a contactor support having a square hole guided reciprocally between the pair of fixed contacts and penetrating along the axis of the fixed contactor, the other end of which is connected to a drive device; In the mounting structure of a contact device, the contact device includes a movable contact that is guided to be movable in the vertical direction via a contact spring and bridges and opens between the fixed contacts by the drive device, A mounting structure for a contact device, characterized in that a locking portion is provided between the fixed contact and the contact surface of the insulating case to prevent the fixed contact from coming off by engaging with the fixed contact. . (2) In the mounting structure for a contact device as described in claim 1 of the utility model registration claim, the locking portion is formed by connecting a cylindrical, spherical, or prismatic protrusion on the insulating case side and a round hole or corner on the fixed contact side. A mounting structure for a contactor device characterized by comprising a hole. (3) In the mounting structure for a contact device as described in claim 1 of the utility model registration claim, the locking portion is formed by connecting a cylindrical, spherical, or prismatic protrusion on the fixed contact side and a round hole or corner on the insulating case side. A mounting structure for a contactor device characterized by comprising a hole. (4) In the mounting structure of the contact device described in claim 1 of the utility model registration claim, the locking portion is composed of a square hole on the insulating case side and a raised tooth-like projection on the fixed contact side. A mounting device for a contact device, characterized in that:
