Claims

[Scope of utility model registration request]

In a capacitor equipped with a safety device in which a capacitor element or a capacitor element assembly is housed in a capacitor case, and the current path is cut by utilizing the deformation of the capacitor case due to an increase in internal pressure in the event of an internal failure, the safety device has a hole or / and an insulating plate provided with a groove to form one or more narrow portions; a lead plate attached to the insulating plate by bridging any of the hole, groove, or narrow portion; and the insulating plate. A capacitor equipped with a safety device, characterized in that a slider is attached to a plate in parallel with the lead plate, and a guide tube is attached to the insulating plate by fitting the slider. .
