Embodiment Construction

[0016] figure 1 , 2 As shown, a lightning protection power connector of the present invention includes a conductive shell 1 and a set of contacts 7 arranged in the conductive shell. The set of contacts 7 is divided into ground contacts, neutral contacts, and live contacts. parts and spare power transfer contacts. The conductive housing 1 has a cavity through the front and back, and the middle part of the cavity is relatively installed with a grounding printed board 3 on the front side and a wiring printed board 4 on the rear side. The grounding printed board 3 A grounding spring 11 is pressed radially between the conductive housing 1 , and the grounding printed board 3 and the conductive housing 1 are conductively connected through the grounding spring 11 . A gas discharge tube GDT is arranged between the grounded printed board 3 and the wiring printed board 4. The gas discharge tube GDT is divided into a first gas discharge tube and a second gas discharge tube, and one end ...

Abstract

The invention relates to a lightningproof power supply connecter which comprises a conductive casing in which a group of connecting pieces are arranged; insulating medium is arranged between the connecting pieces and the conductive casing; first gravitrons are conductively connected between the connecting pieces and the conductive casing; and second gravitrons are conductively connected between live wire connecting pieces and zero wire connecting pieces. In the lightningproof power supply connector, because the gravitrons are conductively connected between the connecting pieces and the conductive casing and between the zero wire connecting pieces and the live wire connecting pieces used for connecting zero wires and live wires, when instantaneous induced overvoltage and overcurrent occur in a circuit in a lightning environment, the breakdown of the gravitrons happens to discharge the overvoltage and overcurrent to a cabinet or earth, thereby protecting equipment form being damaged by the overvoltage and overcurrent.

Description

technical field [0001] The invention relates to a power connector, in particular to a power connector with lightning protection function. Background technique [0002] The power connector is a key component connecting the power supply and the electrical equipment. None of the existing power connectors has the function of lightning protection. During thunderstorms, high instantaneous induced voltage and current will be generated in the connector under the influence of lightning. The induced voltage and current will be transmitted to the device through the power line, which will have a bad impact on the device, and in severe cases, the entire device will be burned. Contents of the invention [0003] The purpose of the present invention is to provide a lightning protection power connector to solve the problem that the existing power connector does not have the lightning protection function. Problems that damage equipment. [0004] In order to achieve the above object, the...
