Abstract

The invention provides a gas discharge tube. The gas discharge tube comprises a discharge tube body and an overvoltage protective board, wherein a plurality of voltage-limiting components are arranged inside the overvoltage protective board or on the outer surface of the overvoltage protective board, the number of the voltage-limiting components is equal to that of intermediate electrodes, and the voltage-limiting components are electrically connected with the intermediate electrodes in a one-to-one mode. The protection effect is better, the response speed is higher, and reliability is higher. The discharge tube body and the overvoltage protective board are electrically connected and are integrated together, and when the gas discharge tube is applied to an overvoltage protection circuit, the working procedure of welding of the voltage-limiting components is omitted; when the gas discharge tube is applied, the welding technology is simple, processing is easier and more convenient, processing efficiency is improved, the layout area and the space of a whole circuit board are reduced, and layout of the circuit board can be conveniently and reasonably planned.

Description

technical field [0001] The application belongs to the technical field of overvoltage protection, and in particular relates to a gas discharge tube. Background technique [0002] In the field of overvoltage protection technology, ceramic gas discharge tubes and semiconductor discharge tubes are often used in the first or first two stages of multi-level protection circuits to discharge lightning transient overcurrent and limit overvoltage. Existing gas discharge tubes include patch discharge tubes, plug-in diode discharge tubes and plug-in three-electrode discharge tubes. The structure of existing patch discharge tubes can refer to figure 1 For the gas discharge tube 110 shown, the structure of the existing plug-in diode discharge tube can refer to figure 2 The gas discharge tube 210 shown, the structure of the existing plug-in triode discharge tube can refer to image 3 A gas discharge tube 310 is shown. The working principle of the above three gas discharge tubes is to r...
