[0089] As shown in FIG. 1, Figures 26-27 As shown, when the plug 9 is inserted into the socket, the plug 9 acts on the first drive inclined surface 32 through the negative plug pin 91 to drive the first protective door 3 to switch to the open state, that is, the first protective door 3 slides to the first protective door body 31 to open the first cover plate through hole 22, and the first baffle plate 34 is misaligned with the second cover plate through hole 23, so that the negative plug pin 91 can smoothly pass through the first baffle plate through hole 52 and be inserted into the negative plug sleeve 61 of the negative plug sleeve assembly 6, and the first baffle plate 34 cannot block the positive plug pin 92.
[0090] The DC socket of the embodiment adopts a double-layer protective door structure, the first protective door 3 and the second protective door 4 are staggered and overlapped, and are arranged to slide in two directions perpendicular to each other, so that the space in the length and width directions of the socket is more effectively utilized, the application range is wide, and the DC socket is particularly suitable for asymmetrically arranged jack holes, and the first protective door 3 and the second protective door 4 can both block one cover plate through hole through the body and block another cover plate through hole through the baffle plate, so that a single plug pin cannot be inserted into the plug sleeve, and the anti-electric shock performance of the socket is improved.

And / or, the second protective door body 41 is a block structure. One end of the second protective door body 41 in a second direction is provided with the second driving inclined surface 42, and it is stacked on the first baffle 34 along a third direction. The other end of the second protective door body 41 in the second direction is stacked and connected to the second baffle 43 along a third direction and integrally formed with the second baffle 43.

Further, the first driving inclined surface 32 is adjacent to the clearance hole 33, and the first driving inclined surface 32 is inclined towards the clearance hole 33. In this embodiment, when the first protective door 3 is in the open state, the clearance hole 33 corresponds to the through hole 22 of the first cover plate, and is used to avoid the negative electrode pin 91.
