Problems solved by technology

For example, during the insulation test and withstand voltage test of the power board, the varistor must be isolated from the earth EARTH, and the two cannot be connected together, otherwise the insulation withstand voltage test cannot be performed
For surge test and group pulse test, the varistor must be connected to the ground EARTH, otherwise the varistor cannot absorb the surge voltage and group pulse.
[0003] After the power board is successfully fixed and installed, it is necessary to repeatedly disassemble and re-solder the varistor during various tests. Impact performance

Abstract

An electrical connector used for a power panel comprises a conductive portion and an insulation portion, wherein the conductive portion is arranged on the power panel and is electrically connected tothe connection ends of a first piezoresistor and a second piezoresistor in the surge absorbing circuit of the power panel, and a first hole is formed in the conductive portion; the insulation portionis contacted with the conductive portion and a second hole matching with the first hole is formed in the insulation portion; and when the power panel and the surface plate of the power panel are assembled, the insulation portion is located between the conductive portion and the surface plate of the power panel to electrically isolate the conductive portion from the surface plate of the power panel. By using the electrical connector, an on-site staff can high-efficiently, high-reliably and scientifically carry out insulation, pressing withstanding, surge and pulse group tests on a chassis component, work processes are simplified, and the electronic product of the chassis component can be prevented from being defective.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to an electrical connector and a chassis component for a power board. Background technique [0002] Due to the harsh test conditions of rail transit power supply products, the power board will encounter insulation test, withstand voltage test, surge test and group pulse test during the test process, and different test items will have different test conditions. For example, the varistor must be isolated from the ground EARTH during the insulation test and withstand voltage test of the power board, and the two cannot be connected together, otherwise the insulation withstand voltage test cannot be performed. For surge test and group pulse test, the varistor must be connected to the ground EARTH, otherwise the varistor cannot absorb the surge voltage and group pulse. [0003] After the power board is successfully fixed and installed, the varistor needs to be repeatedly disass...
