A power board temperature rise test device

Abstract

The invention relates to a temperature rise test device for a power board, comprising a thermocouple, a workbench, a support frame that is arranged on the workbench and can be placed above the power board to be tested, and a mounting seat for fixing the thermocouple, and the support frame A guide hole is provided on the top, and the mounting seat can be slidably installed in the guide hole, and the mounting seat can move up and down relative to the support frame so that the thermocouple is against the temperature rise test position of the component to be tested. The temperature rise test device of the power board realizes the contact with the parts to be tested through the up and down adjustment of the mounting base, which effectively ensures the tightness of the contact between the thermocouple and the parts to be tested, and ensures that it can truly reflect the temperature of the parts to be tested during the test. Temperature rise data for components. And in the process of operation, there is no need to fix and paste the thermocouple on the parts to be tested, the operation is simple and fast, and the work efficiency is high. And the separation between the thermocouple and the parts to be tested is convenient, and will not affect subsequent use.

Description

technical field [0001] The invention relates to a temperature rise test device for a power board. Background technique [0002] The temperature rise test of the power board is an important work content of the electrical safety inspection of household appliances. During the temperature rise test, a thermocouple is usually used to convert the temperature signal into an electrical signal, and then obtain the temperature rise data. In order to obtain accurate temperature rise data, thermocouples are usually pasted on the surface of the detection parts by means of fixing such as pasting. For example, the authorized announcement number is CN201637497U (application number is 200920215592.3) Chinese utility model patent "Embedded Smart Home Appliance Temperature Rise Test Device", in which the disclosed test device is about to use the thermocouple probe for testing to be arranged on-site. Position and fix it, and then realize the temperature test. First of all, the thermocouple n...

AI Technical Summary

Problems solved by technology

First of all, the thermocouple needs to be fixed manually, which takes a long time

In addition, after the thermocouple is manually fixed, the tightness of the connection between the thermocouple and the component under test cannot be guaranteed, which will cause test errors during the test

In addition, after the temperature rise test, each thermocouple needs to be removed separately, which is low in work efficiency, and when the separation is performed, it is easy to cause certain damage to the parts under test and the thermocouple, which will affect the secondary use

And if it is fixed by colloidal bonding, colloid will remain on the measured parts and thermocouples, which will affect its subsequent use.
