In the present embodiment, one test interface 102 corresponds to one load 200, and one load 200 corresponds to one manual reset relay 300, one first indicator lamp 400, and one second indicator lamp 500. When the aging test is carried out, the power adapter is placed in the first compartment 110, the input end of the power adapter is connected with the power supply socket 101, the output end of the power adapter is connected with the corresponding test interface 102, and after the wiring of a circuit is checked to be correct, the master control switch 103 is turned on to carry out power-on aging. After the manual reset relay 300 is powered on, an operator manually triggers the manual reset relay 300 to enable the normally closed contact of the manual reset relay 300 to be conducted, and the second indicator light 500 is turned on. In the aging test process, after the power adapter triggers the protection function and is powered off, the manual reset relay 300 is switched between the normally open contact and the normally closed contact, so that the lighting states of the first indicator lamp 400 and the second indicator lamp 500 are changed, namely the second indicator lamp 500 is turned off, and the first indicator lamp 400 is turned on.

It is contemplated that the first indicator light 400 and the second indicator light 500 may be beads having different colors for easy distinction.

With continued reference to fig. 1 or 2, in order to facilitate the operation of the manual reset relay 300 and the observation of the first indicator light 400 and the second indicator light 500, the support plate 104 is disposed in the second compartment 120, the support plate 104 is mounted on the edge portion of the frame 100, the plurality of housings 105 are mounted on the support plate 104, one manual reset relay 300, one first indicator light 400 and one second indicator light 500 are disposed in each housing 105, the manual reset relay 300 is provided with the reset switch 301, and the reset switch 301, the first indicator light 400 and the second indicator light 500 are exposed outside the housing 105.

When the master control switch 103 is turned on, the timer 600 starts timing, when a power adapter triggers a protection function and is powered off, the corresponding timer 600 is turned off and the timing is cleared, and when the power adapter is powered on again, the timer 600 starts timing again. By comparing the timing time between different timers 600 in the same batch, the time when the power adapter triggers the protection function can be known, which is beneficial to providing reference data for subsequent function analysis. It should be noted that the number of the power adapters performing aging in each batch is multiple, for example, 6 or more, and the probability that the power adapters in the same batch all trigger the protection function is very small and can be ignored.

Referring to fig. 1, in the present embodiment, the number of the compartments is 4, wherein two compartments located in the middle of the frame 100 are the first compartments 110, and the remaining two compartments are the second compartments 120. The first compartment 110 is arranged in the middle of the frame 100, so that the height of the first compartment 110 is suitable for the standing or squatting height of a human body, the comfort of an operator when the operator is connected with a power adapter is improved, and the requirement of humanized design is met.
