[0027] The clamping assembly includes a clamp 1 and a driving device, wherein the clamp 1 is slidably connected to the guide rail 2, and the driving device is connected to the clamp 1 and drives the clamp 1 to move along the guide rail 2;

[0028] The socket fixing position 3 corresponds to the position of the clamp 1; an arc extinguishing device for assisting in extinguishing the arc is provided on a side of the socket fixing position 3 close to the clamping assembly.

[0029] In the embodiments of the present application, in response to the highly dangerous and unavoidable problems in the prior art, the present application provides a solution for automatically plugging and unplugging a plug and being provided with an arc extinguishing device, specifically: comprising a clamping assembly, a guide rail 2, a socket fixing position 3 and a timer for recording the duration of the current when the plug to be tested is unplugged from the socket; the clamping assembly comprises a clamp 1 and a driving device, the clamp 1 is slidably connected to the guide rail 2, the driving device is connected to the clamp 1 and drives the clamp 1 to move along the guide rail 2; the socket fixing position 3 corresponds to the position of the clamp 1; the side of the socket fixing position 3 close to the clamping assembly is provided with an arc extinguishing device for assisting in extinguishing the arc. The timer records the duration of the current generated during the automatic plugging and unplugging of the plug driven by the clamping assembly, and cooperates with the arc extinguishing device to extinguish the arc, thereby achieving the technical effect of avoiding damage to the test environment and personnel caused by leakage or fire of the device during the test.

[0030] Next, the plug insertion and extraction test device in this exemplary embodiment will be further described.

[0031] In one embodiment of the present application, the plug insertion and extraction test device comprises: a clamping assembly, a guide rail 2, a socket fixing position 3, and a timer for recording the current duration when the plug to be tested is pulled out of the socket;

[0032] The clamping assembly includes a clamp 1 and a driving device, wherein the clamp 1 is slidably connected to the guide rail 2, and the driving device is connected to the clamp 1 and drives the clamp 1 to move along the guide rail 2;

[0033] The socket fixing position 3 corresponds to the position of the clamp 1; an arc extinguishing device for assisting in extinguishing the arc is provided on a side of the socket fixing position 3 close to the clamping assembly.

[0034] It should be noted that the automatic plug-in and plug-out drive mechanism allows testers to remotely control the device for testing, preventing damage to the testing environment and personnel from electrical leakage or fire during plug-in and plug-out testing. The timer can record the duration of the current flow while the plug is removed from the socket.
