Abstract
Provided is an integrated gas discharge tube. In the integrated gas discharge tube, the structure of the gas discharge tube is regulated into an upper cover and an insulative base, and the internal side surface and the external side surface of the bottom surface of the insulative base are respectively subject to electrode integration, so that the discharge effect of the gas discharge tube is effectively increased and the preparation process and the preparation flow of a multi-terminal-to-ground gas discharge tube are greatly simplified so as to greatly simplify the preparation process and to realize batch production and high integration of the gas discharge tube. Also provided is a preparation method for an integrated gas discharge tube.
