The test connection module 2 includes a male unit 21 and a female unit 22. The power-on protection module 3 is connected with the female seat unit 22, and the male head unit 21 is detachably connected with the female seat unit 22. The connection identification module 4 has a sensing end for monitoring the state information of the male unit 21 connected to the female unit 22, and further obtaining the connection state information of the male unit 21 and the female unit 22.

In addition, in another embodiment, the connection identification module 4 may further adopt an opposite-type photoelectric sensor to monitor whether the male seat unit 21 moves in place, and further determine the connection state of the male seat unit 21 and the female seat unit 22, in a specific application, the opposite-type photoelectric sensor of the connection identification module 4 is adjacent to a side wall of the female seat unit 22 having the insertion hole, and when the male seat unit 22 is inserted, the opposite-type photoelectric sensor is blocked by the male seat unit 21 and disappears, and then it is determined that the male seat unit 21 and the female seat unit 22 are in the connection state.
In addition, the connection identification module 4 can also be replaced by a human in a specific application. Specifically, the male socket unit 21 of the test connection module 2 can be manually inserted into the female socket unit 22 by a human, for example, a plug is inserted into a socket; after the insertion, the connection state information of the male seat unit 21 and the female seat unit 22 is determined manually, and then, a connection state information is manually provided to the control module 5, so that the power-on detection protection module 3 is turned on, for example, a switch is manually provided to the control module 5, and the control module 5 controls the power-on protection module 3 to be turned on.
