Power supply module production test tool

Abstract

The invention discloses a power supply module production test tool comprising a flat plate, a power source module being tested is mounted on an upper surface of the flat plate, the power source modulecomprises an input end and an output end, the input end is connected with a direct current stabilized voltage power source, a first ammeter and a switch are connected in series and a first voltmeteris connected in parallel on a connection line between the direct current stabilized voltage power source and the input end, and the output end is connected with a load module which is connected with the switch in series; the load module comprises a first load, a second load and a third load; the first load, the second load and the third load are connected in parallel; the first load, the second load and the third load are connected with a sliding rheostat, a second ammeter and the switch in series; two ends of the first load, the second load and the third load are connected with a second voltmeter in parallel; all basic characteristics of the power supply module in different environments such as different temperature and humidity conditions can be tested via the test tool; a plurality kinds of safety features of the power supply module can be tested, and the test tool is worth popularizing.

Description

technical field [0001] The invention relates to the technical field of power module production, in particular to a test fixture for power module production. Background technique [0002] The test fixture belongs to a category under the fixture. It is a fixture specially used to test and test the function, power calibration, life, and performance of the product. It is mainly used for testing various indicators of the product on the production line. In the production process of the power module, in order to understand the characteristics of the power module, it is also necessary to use a dedicated test fixture. [0003] However, the existing power module test fixtures have the following defects. One is that the existing power module test fixtures usually only test the input characteristics, output characteristics and load characteristics of the power module, while the leakage current, isolation voltage and insulation of the power module Resistance, etc. are not measured, so t...

Problems solved by technology

[0003] However, the existing power module test fixtures have the following defects. One is that the existing power module test fixtures usually only test the input characteristics, output characteristics and load characteristics of the power module, while the leakage current, isolation voltage and insulation of the power module Resistance, etc. are not measured, so that the safety of the power module cannot be guaranteed; second, the power module will be affected by the surrounding environment such as temperature and humidity in actual use, and the existing power module test fixtures cannot be tested in different environments According to the characteristics of the power module, in order to solve these problems, a test fixture for the production of power modules is designed
