The locking members 75 are hingedly connected to the terminal block 1. The pressing member 72 is provided on the lower side of the button 71. The pressing member 72 is provided on one side of the locking member 75. The locking member 75 is provided on the other side with a limiting boss 76 that matches the limiting slot 37. The plurality of locking members 75 are arranged at intervals on the lower side of the pressing member 72.

[0029] The plug 3 is locked in the slot 2 by the cooperation of the limiting boss 76 and the limiting groove 37; when the button 71 is pressed, the pressing member 72 drives the locking member 75 to rotate, and the limiting boss 76 disengages from the limiting groove 37, which can unlock multiple plugs at the same time, thereby improving the efficiency of pulling out the plug 3 and improving the efficiency of electrical detection.

[0030] Among them, the locking member 75 is hinged to the junction box 1 through a rotating shaft 73; a spring mounting groove 77 is provided on one side of the locking member 75, and a return spring is provided in the spring mounting groove 77, one end of the return spring is connected to the locking member 75, and the return spring is used to maintain the locking state of the plug.

[0031] like Figure 1 、 Figure 5 and Figure 6The slot 2 includes a first slot 21, a second slot 22, a third slot 23 and a fourth slot 24. The plug 3 includes a first plug 31, a second plug 32, a third plug 33 and a fourth plug 34. The first slot 21 cooperates with the first plug 31; the second slot 22 cooperates with the second plug 32; the third slot 23 cooperates with the third plug 33; and the fourth slot 24 cooperates with the fourth plug 34.
