Claims

[Scope of Claim for Utility Model Registration] A fitting part is formed on the fixed side base, and an insertion hole passing through the center of the bottom of the fitting part is formed, and the vicinity of the base end of the fixed arcing contact located at the axial center of the fitting part is formed. A stopper that loosely fits into the insertion hole and has a larger diameter than the insertion hole is formed at the base end of the fixed arcing contact, and a biasing means for urging the stopper toward the tip of the fixed arcing contact; A flexible conductor is provided to electrically connect between the fixed side bases, and a fixed main contact is provided on the inner circumferential surface of the fitting part, while a puffer cylinder is fixedly provided opposite the fitting part of the fixed side base, and the puffer cylinder A movable main contact is provided within the cylinder so as to be able to reciprocate, and is interlocked and connected to the drive means, and a piston that is slidably provided within the puffer cylinder and forms a puffer chamber is coupled to the movable main contact, and is movable at the tip of the movable main contact. An arcing contact is provided, and a flow path formed by penetrating the movable arcing contact toward the base end of the movable main contact is communicated with the puffer chamber, and the fixed arcing contact is inserted into the flow path of the movable main contact so as to be able to freely make sliding contact. A gas disconnector that is characterized by being made to leak.
