Abstract

The invention provides a compound gas discharge tube. The compound gas discharge tube comprises an insulating tube body and at least two electrodes, wherein at least one electrode is provided with an extending end; at least one patch element is integrated on at least one side face of the insulating tube body; and a conducting plane of the patch element and the outer side face of the extending end of the electrode are coplanar or approximately coplanar. According to the compound gas discharge tube provided by the invention, other electronic elements needing to be used together with an ordinary gas discharge tube are integrated around the compound gas discharge tube, effective overvoltage protection can be provided for a circuit, the integration level of a protective circuit can also be improved, the product dimensions are reduced, and the compound gas discharge tube is more convenient when the circuit is externally connected.

Description

technical field [0001] The invention relates to the field of overvoltage protection products, in particular to a composite gas discharge tube. Background technique [0002] The gas discharge tube is a switch type protection device, usually used as an overvoltage protection device. The gas discharge tube commonly used at present is made of an insulating tube body and electrodes sealed at both ends, and the inner cavity is filled with inert gas. When the voltage across the electrodes of the gas discharge tube exceeds the breakdown voltage of the gas, a gap discharge will be caused, and the gas discharge tube will quickly change from a high-resistance state to a low-resistance state, forming a conduction, thereby protecting other devices connected in parallel with it. . However, due to the performance limitation of the gas discharge tube, in the practical application of some protection circuits, the use of the gas discharge tube alone often fails to meet the requirements. It ...
