For chargers with various sizes and specifications, it will waste huge manpower and material resources, poor feasibility, and low production capacity.

At the same time, when conducting the electrical performance test of the charger, each group of AC thimbles is connected to the AC power supply, and the USB plug is connected to the electronic load instrument; The thimble is connected to the AC end of the high-voltage machine; the corresponding wires of the same USB plug are short-circuited, and the USB plug end is connected to the DC end of the high-voltage machine. This connection method has the following disadvantages: (1) multiple wires connecting multiple instruments are criss-crossed and messy, and there is a risk of crossing each other and causing a short circuit; (2) when a USB charger multi-channel test device is used by the tester When the high-voltage short-circuit test is replaced by the electrical performance test or from the electrical performance test to the high-voltage short-circuit test, it is necessary to change the connection mode between the AC thimbles and the USB plug wires, and all the original connections must be changed. Dismantle all the test equipment, and then reconnect according to the replacement needs. The whole process is tedious and tiring, and professional electricians are required to connect one by one. It is a waste of time and it is easy to make wiring errors, causing unnecessary troubles; (3) when a USB charger When the multi-channel test device is moved from one place to another, it is also necessary to remove all the connected equipment first, and then reconnect, causing a great waste of manpower.
