Claims

[Scope of Claim for Utility Model Registration] (1) A capacitor element is housed in a cylindrical outer case with a bottom, the opening of which is sealed with a sealing plate having an explosion-proof valve, and the capacitor element is drawn out from the capacitor element. In an electrolytic capacitor in which an anode lead and a cathode lead are respectively connected to an anode terminal and a cathode terminal provided on the sealing plate,
The electrolytic capacitor itself is stored in a bottomed cylindrical safety case with an O-ring attached around it so that a bottom space of a predetermined volume is created, and
A second sealing plate having a pair of external terminals is provided on the opening side of the safety case, and a pair of internal sealing plates, at least one of which acts as a fuse wire, are provided between the anode terminal and the cathode terminal and each of the external terminals. Wire the lead wires, divide the inside of the safety case into the bottom space and the airtight top space using the O-ring, and insert the outer case into the bottom space of the safety case to insert the object to be detected. An electrolytic capacitor characterized by being provided with an electrical sensor. (2) The electrolytic capacitor according to claim 1, wherein the electrical sensor comprises a pair of probes penetrated through the bottom of the safety case so as to be in contact with the bottom of the outer case for electrical continuity. . (3) The electrolytic capacitor according to claim 1, wherein the other internal lead wire has a longer dimension than the one internal lead wire that acts as a fuse wire, and is made of a wire material that is difficult to cut. (4) The electrolytic capacitor according to claim 1, further comprising a spacer that can be deformed by a predetermined pressure between the outer bottom surface of the outer case and the inner bottom surface of the safety case.
