Abstract

The present invention provides a composite gas discharge tube which comprises an insulating tube body and at least three electrodes which comprise a first electrode, an intermediate electrode and a second electrode. The first electrode, the intermediate electrode and the insulating tube body are connected in a sealed way to form a discharge inner chamber filled with gas. The surface of the intermediate electrode facing the second electrode is provided with a chip component or a chip component group. The chip component or chip component group comprises two conductive surfaces which are a first conductive surface and a second conductive surface. The first conductive surface is electrically connected to the intermediate electrode, and the second conductive surface is electrically connected to the second electrode. According to the composite gas discharge tube, the chip component which is used with a common gas discharge tube in series is packaged in the composite gas discharge tube, the degree of integration is high, the size is small, and the external connection of a circuit is convenient.

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 protective circuits, the use of the gas discharge tube alone often fails to meet the requirements, and...
