Claims

[Scope of utility model registration request]

An annular structure formed outside the main body of a synthetic resin lower cover in which a plurality of current-limiting elements made of zinc oxide as a main component and divided into circular or semi-circular shapes are fixed to the lower end opening of the cylindrical porcelain body. Arranged in an annular manner for the storage compartment of
Moreover, one of the side end surfaces of each of the above elements is connected to the upper terminal,
Further, the other side end surface is connected to the lower terminal, and each of the above-mentioned elements is connected in parallel to the above-mentioned upper and lower terminals,
The above-mentioned upper terminal is connected to a lower fixed electrode inside the main body, and the above-mentioned lower terminal is connected to a discharge electrode, and further the connected discharge electrode is opposed to the flash angle of the mounting fitting via a discharge gap. Cylindrical cutout with current limiting element.
