続した通信用避雷器。 A discharge tube has electrodes at both ends with a recess in the center, one electrode is tightly attached to an electrode plate with a through hole in the center, and the other electrode is held by crimping with a terminal plate that also serves as a leaf spring. Hold the low-alloy metal with a convex part in an insulating holder, pass the convex part of the low-alloy metal through the electrode plate with a through hole in the center, and insert it into the concave part of the discharge tube, and the insulating holder is biased with a leaf spring. Insert and fix the discharge tube, electrode plate, low-fusion metal, and insulating holder from above the terminal plate that is in close contact with the other electrode of the discharge tube, and then stretch the end of the leaf spring on the insulating holder side. In the installation state described above, the electrode plate and the insulation space are maintained at an insulation distance equivalent to the discharge voltage of the discharge tube or higher, but if the discharge tube becomes overheated and the low alloy alloy melts, the plate The electrode plate is displaced by the force of the spring and comes into contact with the electrode plate, creating a short circuit via the terminal plate and the plate spring.
A lightning arrester for communications, comprising: an external connection terminal, a terminal plate as a second external connection terminal, and a varistor having a varistor voltage higher than the discharge starting voltage of the discharge tube connected between the electrode plate and the terminal plate.
