Withstand voltage testing device for printed circuit board

Abstract

The invention discloses a withstand voltage testing device for a printed circuit board, and the device comprises a withstand voltage tester and a testing tool. The withstand voltage tester is provided with a high-voltage output end and a testing loop low end. The testing tool comprises a bottom plate and a bearing assembly, and the front surface of the bottom plate is provided with a plurality of groups of detection probe units which are corresponding to a plurality of PCS plates in a one-to-one manner. Each group of detection probe units consist of a first detection probe in electrical connection with the high-voltage output end, and a second detection probe in electrical connection with the testing loop low end. The bearing assembly is disposed above the front surface of the bottom plate, and can elastically move relative to the front surface of the bottom plate. The elastic displacement of the bearing assembly can enable the plurality of detection probe units to be inserted into and separated from the bearing assembly, thereby enabling the plurality of detection probe units to be connected and disconnected with the corresponding PCS plates. The device can complete the withstand voltage testing among the plurality of PCS plates on the printed circuit board at a time, and greatly improves the detection efficiency.

Description

technical field [0001] The invention relates to the technical field of printed circuit boards, and specifically provides a printed circuit board withstand voltage testing device. Background technique [0002] Based on the requirements for the reliability of printed circuit board products, it is necessary to conduct withstand voltage tests to evaluate the ability of the printed circuit board to withstand high voltage. A printed circuit board is composed of multiple PCS boards, and the withstand voltage capability of a printed circuit board is the electrical insulation capacity between two PCS boards. [0003] In the prior art, a withstand voltage tester is usually used to test the withstand voltage capability of a printed circuit board. During the test, respectively connect the positive and negative test terminals of the withstand voltage tester to the two PCS boards to be tested in the printed circuit board, and apply the voltage required for testing by the withstand voltag...

AI Technical Summary

Problems solved by technology

However, when using the above test method for withstand voltage test, only two PCS boards to be tested can be tested for withstand voltage at a time, and a printed circuit board is usually composed of multiple PCS boards, so the test of a printed circuit board is completed It will take too long and the test efficiency is very low

In addition, the above test methods are usually done manually by the operator, so for the operator, not only the work intensity is high, but also there is a certain degree of safety hazard
