Description

A DIN rail type electric energy meter point error detection fixture

technical field

The utility model relates to a detection fixture, in particular to a DIN guide rail type electric energy meter point error detection fixture.

Background technique

The vibration frequency of the DIN rail type electric energy meter may damage the internal core PCBA of the product during ultrasonic welding, which may affect the product performance. In order to ensure product quality and eliminate hidden dangers. Generally, most electric energy meter manufacturers need to do a single-point error full inspection on the product after ultrasonic welding to ensure that the functional error of the product is not affected by ultrasonic welding. The commonly used method is to use large-scale verification equipment to put on the shelves again for verification and testing, or use a single product to use "crocodile clips" for testing. The disadvantages of the two methods are low work efficiency, long operation time, low test success rate and low operator safety details, which are not conducive to mass production testing.
