The operation key 22 is in the first operation position to drive the connection conductor 21 in a conductive state in which the first conductor 151 and the second conductor 152 are conductive, and the operation key 22 is in the second operation position to drive the connection conductor 21 in a separated state in which the first conductor 151 and the second conductor 152 are disconnected. The driving member 30 is movably disposed through the base 11, the driving member 30 includes a driving portion 31 driven by the external plug 40 and a blocking portion 32 located below the operation key 22, the driving portion 31 is driven to move when the external plug 40 is inserted into the base 11 and electrically connected to the second conductor 152, and the blocking portion 32 blocks the operation key 22 to keep the operation key 22 at the second operation position.

By applying the technical solution of this embodiment, the plug connector of the LED display device can be installed at the side of two adjacent display units, the first conductive member 151 is connected to the power supply of one display unit, and the second conductive member is connected to the power supply of the other display unit. Since the driving member 30 is movably disposed through the seat body 11.

Thus, the on state and the off state of the first conductor 151 and the second conductor 152 of the socket 10 can be known to be in the off state without manual recognition, thereby avoiding manual recognition errors or misoperation in the on state and further reducing the possibility of accidents. Therefore, the technical scheme of the embodiment solves the problems that the on state and the off state of the socket 10 in the related art need to be identified manually, and errors or misoperation is easy to identify. Of course, when the external plug 40 is not inserted into the seat 11, the blocking portion 32 can move along with the operation key 22, so that the operation key 22 is switched between the first operation position and the second operation position.
