Claims

[Claims for Utility Model Registration] {1} A plurality of insulating tubes sandwiching intermediate electrodes are gas-sealed with a pair of end electrodes, and the terminals of the intermediate electrodes and the flanges of the end electrodes are connected from the outer peripheral surface of the insulating tubes to the terminals of the intermediate electrodes and the flanges of the end electrodes. In a gas discharge tube type three-electrode lightning arrester for communications, each of which has a protruding terminal, the terminal is provided with an engaging portion at an inner diameter position from the flange, and the terminal is pressed against the flange through an insulating material that is melted by discharge heat. 1. A short-circuiting mechanism for a gas discharge tube type triode lightning device for communications, characterized in that a short-circuiting piece is engaged approximately at its center with the above-mentioned engaging portion. (2) A short-circuiting mechanism for a gas discharge tube type three-electrode lightning arrester for communication, as set forth in claim 1 of the utility model registration claim, characterized in that the retaining portion is an insertion hole. (3) A short-circuiting mechanism for a gas discharge tube type three-electrode lightning arrester for communication, as set forth in claim 1 of the utility model registration claim, characterized in that the retaining portion is a notch.
