Claims

[Scope of utility model registration request]

An insulating case having a side wall, a contact part connected to a load electronic contact part provided in the insulating case at the negative end, and a contact part of a neutral copper strip attached to the insulating case at the other end. It has a contact part that comes into contact with the
A contact element formed in a protruding shape and movable in the vertical direction within the insulating case, and a contact element disposed between the lower surface of the almost inverted U-shaped protrusion of the contact element and the insulating case, A press-contact spring is provided for press-contacting the contact portions at both ends of the terminal to the contact portions of the load terminal and the contact portion of the neutral copper strip, respectively, and a press-contact spring is disposed on the upper surface of the approximately inverted U-shaped protrusion of the contact. It has a leaf spring and a cam at its tip that contacts the upper surface of the leaf spring, and is rotatably disposed in an insulating case via a pivot attached to the cam, and is connected to a load terminal through the contactor. A distribution board neutral terminal comprising an operating handle for opening and closing a copper band clamp connection.
