Specifically, the third connection hole is arranged corresponding to the third through hole 2521 of the wire waterproof cover 252, the number of the fourth connection holes is six, the six fourth connection holes are arranged corresponding to the six plug signal terminals 223, and the six fourth connection holes are arranged corresponding to the six fourth through holes 2522 of the wire waterproof cover 252.

[0062] In one embodiment, in combination Figure 1 and Fig.10 As shown, the 9PIN connector further includes a locking mechanism 30, and when the plug housing 21 is inserted into the socket housing 11, the locking mechanism 30 is used to lock the plug housing 21 with the socket housing 11. The locking mechanism 30 locks the plug housing 21 with the socket housing 11, thereby ensuring that the 9PIN plug 20 and the 9PIN socket 10 are stably connected and not easily disengaged.

[0063] In one embodiment, in combination Figure 1 and Figure 2 As shown, the locking mechanism 30 includes a first buckling structure 31 provided on the fixing member 191 and a second buckling structure 32 provided on the plug housing 21. When the plug housing 21 is inserted into the socket housing 11, the first buckling structure 31 can be buckled with the second buckling structure 32. On the one hand, the fixing member 191 is connected to the socket housing 11 through the threaded fastener 192, thereby fixing the socket housing 11 on the housing 40 of the device, and pressing the waterproof pad 12 between the inner wall of the socket housing 11 and the housing 40 of the device, thereby ensuring the waterproof effect between the socket housing 11 and the device. On the other hand, the fixing member 191 is provided with the first buckling structure 31. Through the buckling of the first buckling structure 31 and the second buckling structure 32, the 9PIN plug 20 and the 9PIN socket 10 are stably connected and not easily disengaged.

[0064] In one embodiment, in combination Figure 1 , Fig.10and Fig.11 As shown, the locking mechanism 30 includes a first buckling structure 31, a second buckling structure 32, a mounting seat 33, a sliding seat 34, a spring 35 and a slider 36. The first buckling structure 31 is arranged on the outer wall of the socket housing 11, the mounting seat 33 and the sliding seat 34 are both arranged on the outer wall of the plug housing 21, the second buckling structure 32 is rotatably arranged on the mounting seat 33, one end of the second buckling structure 32 is used to buckle with the first buckling structure 31, and the other end of the second buckling structure 32 is connected to the slider 36 through the spring 35. The slider 36 is slidably arranged on the sliding seat 34, and the sliding seat 34 has an inclined surface 341 inclined toward the socket housing 11. When the slider 36 slides on the inclined surface 341, it can drive the second buckling structure 32 to rotate. For the convenience of explanation, it is assumed that the plug housing 21 and the socket housing 11 are plugged in the horizontal direction, and the locking structure is located above the plug housing 21 and the socket housing 11. When the plug housing 21 needs to be inserted into the socket housing 11, the slider 36 is pushed by hand to slide on the inclined surface 341 in the direction close to the socket housing 11, that is, slides toward the lower left. When the slider 36 slides, the spring 35 between the second buckling structure 32 and the slider 36 is compressed. Since the second buckling structure 32 is rotatably arranged on the mounting seat 33, the second buckling structure 32 rotates clockwise by utilizing the principle of leverage, that is, the end of the second buckling structure 32 connected to the spring 35 moves toward the lower left as the slider 36 slides, and the end of the second buckling structure 32 away from the spring 35 moves toward the upper right, so that the second buckling The purpose of moving the end of the structure 32 away from the spring 35 toward the upper right is to avoid the second snap-on structure 32 from colliding with the first snap-on structure 31 when the plug housing 21 is inserted into the socket housing 11, so that the plug housing 21 can be smoothly inserted into the socket housing 11. When the plug housing 21 is successfully docked with the socket housing 11, the slider 36 is released by hand. Under the elastic force of the spring 35, the slider 36 can automatically slide on the inclined surface 341 in the direction away from the socket housing 11, that is, slide toward the upper right. Using the principle of leverage, the second snap-on structure 32 will rotate counterclockwise, that is, the end of the second snap-on structure 32 connected to the spring 35 will move toward the upper right with the sliding of the slider 36, while the end of the second snap-on structure 32 away from the spring 35 will move toward the lower left, so that it can be snapped with the first snap-on structure 31. When it is necessary to disassemble the first snap-connecting structure 31 and the second snap-connecting structure 32, the slider 36 is pushed by hand to slide on the inclined surface 341 toward the direction close to the socket housing 11, that is, slide toward the lower left, and the second snap-connecting structure 32 rotates clockwise. The end of the second snap-connecting structure 32 away from the spring 35 moves toward the upper right and disengages from the first snap-connecting structure 31, so that the plug housing 21 can be smoothly pulled out of the socket housing 11.

[0065] Specifically, Fig.10As shown, the first buckle structure 31 is a convex block, and the second buckle structure 32 is provided with a bayonet 321 at one end away from the spring 35, so that the bayonet 321 is sleeved on the convex block, thereby realizing the buckle connection between the first buckle structure 31 and the second buckle structure 32. Of course, in some other embodiments, the first buckle structure 31 can be a slot, and the second buckle structure 32 can be a hook, and the first buckle structure 31 and the second buckle structure 32 can be buckled by hooking the hook in the slot.
