Claims

[Claims for Utility Model Registration] 1. An insulating outer cylinder, in which an insulating core is provided between an upper electrode and an intermediate electrode fixed to both upper and lower ends of an insulating outer cylinder, and a fuse element is wound around the outer circumference of the insulating core to connect the two electrodes. In the current limiting fuse, a lower electrode connected to the intermediate electrode is provided on the outer periphery of the approximately central part of the fuse, and the intermediate electrode is formed into a ring having an insertion hole so as to come into contact with the end surface of the insulating outer cylinder. It is arranged in contact along the outer circumference of the outer cylinder,
An electrode structure for a current limiting fuse, characterized in that a conductive plate connected to the lower electrode is integrally provided. 2. At a peripheral edge of the intermediate electrode, 180 degrees opposite to the conductive plate, a retaining piece is provided which contacts the outer periphery of the insulating outer cylinder and cooperates with the conductive plate to secure the intermediate electrode to the insulating outer cylinder in a pinched manner. An electrode structure for a current-limiting fuse according to claim 1, which is characterized in that: 3. The current-limiting fuse electrode according to claim 1 or 2 of the utility model registration claim, characterized in that the insertion hole of the intermediate electrode is formed with a recess for preventing disconnection of the fuse element into which the fuse element is inserted. structure.
