Abstract

A four-channel overcurrent and overvoltage protection tester includes a casing (10), at least four detection interfaces (20) arranged on the surface of the casing (10), and a detection circuit ( 30), a control circuit (40) controlling the detection circuit, and a power supply unit (50) connected to the control circuit (40), and the at least four detection interfaces (20) are respectively connected to the detection circuit (30) and the control circuit (40). Because it can test 4 products at the same time, there is no need for employees to dial the toggle switch to meet the corresponding test requirements during the test, so the test speed is greatly improved, which can reach 8 times that of a single manual test. The test speed has been increased by 8 times, and the fatigue of employees has been reduced by 80%, which greatly saves the cost of production.

Description

technical field [0001] The invention relates to a detection technology, in particular to an automatic test of a small power adapter PCBA. Background technique [0002] At present, the detection of small-power adapter PCBA boards is generally carried out on a single piece. Due to the complicated and cumbersome wiring, this kind of detection is time-consuming and laborious, so the efficiency is not high. When testing in large quantities, a large number of testing personnel are required, and the labor efficiency is relatively high. Low. Contents of the invention [0003] The invention provides a four-channel overcurrent and overvoltage protection tester, which can test four PCBAs at the same time, and the test steps are completed in one step, so as to solve the technical problem of low test efficiency in the prior art. [0004] The four-channel overcurrent and overvoltage protection tester provided by the present invention to solve the above technical problems includes a hou...
