Description

Tool for testing direct-current voltage converter

Technical Field

The utility model relates to a test auxiliary device, in particular to a tool for testing a direct-current voltage converter.

Background

Direct-current voltage converters are commonly known as DC/DC converters and are widely used in production and living. The DC voltage converter is usually tested by a DC/DC converter test system, and various performance indexes such as output voltage, voltage adjustment rate, load adjustment rate, ripple voltage and efficiency are qualified and can be put into use. When in testing, each pin of the tested DC/DC converter is led out and sent to the corresponding position of the testing machine, and as the packaging type of the DC/DC converter is up to dozens of types, the pin arrangement is different, and the universal design is not available at present, one-by-one testing is often carried out, and each testing process comprises three stages of 'assembling', 'testing' and 'disassembling', wherein 'assembling' and 'disassembling' occupy a certain proportion in the whole testing duration. When the number of the tested DC/DC converters is large, the assembly and disassembly occupy too much time, so that the testing is complex and the testing efficiency is low. In addition, a test board is separately provided for each package type DC/DC converter, and there is no problem in terms of use, but the cost is too high, and the test boards of some package type DC/DC converters are rarely used.

Aiming at the defects in the prior art, the utility model provides a tool for testing a direct-current voltage converter, which adopts a structure form that a tested device seat is combined with an upper plate and a lower plate, thereby not only meeting the actual requirements of production, but also effectively controlling the cost and greatly improving the test efficiency. The utility model has the advantages of low cost, simple structure, easy manufacture and convenient use.
