Description

technical field [0001] The invention relates to a discharge tube technology, in particular to an integrated gas discharge tube and a preparation method thereof. Background technique [0002] The traditional diode gas discharge tube consists of 2 metal electrodes, 2 solders, and a ceramic insulating tube with a metallized layer sealed to form a discharge gap; the electrodes are coated with cathode emission materials, and there are 2 or more on the ceramic insulating tube Trigger conductive strips such as figure 1 As shown, two metal electrodes 1, two solders 2, one ceramic insulating tube 3 with a metallization layer 32, and at least two conductive strips 31 on the ceramic insulating tube 3. [0003] The preparation process of the traditional diode gas discharge tube is as follows: [0004] Metal electrodes are mechanically stamped from rods or sheets, then trimmed, polished and cleaned; [0005] The ceramic insulating tube is formed by slurry injection molding or dry pres...

AI Technical Summary

Problems solved by technology

[0010] The discharge effect of the gas discharge tube with the traditional structure is not good, and the complex structure is not conducive to the preparation, for example:

[0011] Traditional gas discharge tubes have many raw material processing procedures, so the cost of raw materials is high;

[0012] Metallized ceramics need to be sintered at a high temperature above 1000 degrees twice, and the solder needs to be smelted at a high temperature of 1000 degrees once. The energy consumption of raw materials is high. In addition, the product needs to be sealed at a high temperature of about 850 degrees. Therefore, the entire supply chain needs to go through three times of high temperature sintering. Conducive to energy saving and emission reduction;

[0013] The traditional gas discharge tube has more processing procedures, and requires more equipment and labor costs, so the cost is higher;

[0014] It is not conducive to the miniaturization and integration of products. If it is necessary to make a multi-pole integrated gas discharge tube, the number of raw materials will increase exponentially, and the cost will also increase exponentially (such as figure 2 As shown, the gas discharge tube with four terminals connected to the ground usually needs 13 parts to be manufactured by using the traditional gas discharge tube processing technology, including 5 electrodes 4, 6 solders 5, and 2 ceramics with metallization layer 61 insulating tube 6);

[0015] The manufacturing process of the traditional discharge tube has many processes and the processing accuracy of raw materials is not high, resulting in large fluctuations in the parameters of the discharge tube
