Claims

[Scope of Claim for Utility Model Registration] (1) Inside the outer body formed by combining the main body case and the lid case, one fixed terminal and a movable contact are provided at one end, and the other end is fixed to the one fixed terminal. The other fixed terminal, which includes a thermal plate and a fixed contact to which the movable contact is press-contacted, is biased by a return spring and engages the movable contact whose one end portion is in press-contact with the fixed contact, and an overcurrent is generated. An operating punch is installed which intervenes in the gap between the fixed contact and the movable contact caused by the reversal action of the thermal plate due to the flowing flow, and whose other end protrudes from the outer body by the biasing force of the return spring. In circuit protectors,
The other end of the operating punch is provided with a storage part shaped so that the return spring can be inserted from the outside, and the return spring is compressed and held at the end of the storage part between the support wall of the outer body. A circuit protector characterized by having a cap attached thereto. (2) A projecting piece that abuts the outer surface of the mounting member is integrally formed on the outer surface of each end of the main body case and the lid case, and an elastic engagement member that contacts the inner surface of the mounting member is formed on the end of the outer body. Claim (1) characterized in that a head cap integrally provided with a stopper is attached.
