[0027] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0029] A connector shell with high docking sealing performance comprises an upper shell 1 and a lower shell 2 that fit together, wherein plug posts 10 are fixed at the four corners of the bottom surface of the upper shell 1, and sockets 20 corresponding to the positions of the plug posts 10 and matching in size are provided at the four corners of the top surface of the lower shell 2. A docking hole 100 is provided near the bottom of the plug post 10, and a fixing mechanism 4 for fixing the plug post 10 is fixed near the tops of the four sides of the left and right side walls of the lower shell 2, and the fixing mechanism 4 comprises a fixing frame 40 fixed to the outer wall of the lower shell 2 near the plug post 20, and a movable plate 42 is slidably connected in the fixing frame 40, and a docking post 43 is fixed in the center of one side of the movable plate 42 near the plug post 20. When the upper shell 1 and the lower shell 2 are buckled together, the docking post 43 passes through the side wall of the lower shell 2 and is inserted into the docking hole 100. The plug post 10 is fixed by the docking post 43, so as to improve the tightness of the connection between the upper shell 1 and the lower shell 2, facilitate separation and combination, and be more practical.

[0030] In this embodiment, sealing gaskets 3 are adhered to the front and rear inner surfaces of the upper shell 1 and the lower shell 2. The two adjacent sealing gaskets 3 are located correspondingly, and the sealing gaskets 3 are U-shaped, which improves the tightness when the upper shell 1 and the lower shell 2 are buckled together.

[0031] Specifically, the fixed frame 40 is U-shaped, and two fixed columns 41 passing through the movable plate 42 are fixed inside the fixed frame 40 . The movable plate 42 slides on the two fixed columns 41 .

[0032] Specifically, two fixing columns 41 are arranged side by side, and an anti-dropping block is fixed to one end of the fixing column 41 close to the lower shell 2 to prevent the movable plate 42 from dropping off from the fixing column 41 .

[0033] Furthermore, a spring 44 is installed between the movable plate 42 and the fixed frame 40 . The spring 44 is located between the two fixed columns 41 . The spring 44 is used to help the movable plate 42 to reset.

[0034] In addition, a positioning column 46 is fixed to the top surface of the fixed frame 40 , and the fixed frame 40 is rotatably connected to a shifting block 45 through the positioning column 46 , which is convenient for users to shift.

[0035] It is worth noting that the shifting block 45 is used to control the position of the movable plate 42 , and a stopper is fixed on the top of the positioning column 46 to prevent the shifting block 45 from being disengaged. The movement of the movable plate 42 can be controlled by shifting the shifting block 45 .

[0036] It is worth noting that a through slot 450 is provided at one end of the shift block 45 close to the movable plate 42, and a control column 47 passing through the through slot 450 is fixed at the center of the top surface of the movable plate 42. After the shift block 45 is shifted, the control column 47 slides in the through slot 450, thereby driving the movable plate 42 to move.

[0037] When the connector housing with high docking sealing performance of the utility model is in use, the upper shell 1 and the lower shell 2 are buckled together so that the plug post 10 of the upper shell 1 is inserted into the plug hole 20 of the lower shell 2. At this time, the docking post 43 is inserted into the corresponding docking hole 100 to prevent the upper shell 1 and the lower shell 2 from separating. At the same time, the sealing gasket 3 can improve the sealing performance. When it is necessary to separate the upper shell 1 and the lower shell 2, the shift block 45 is shifted, and the shift block 45 rotates, and the control column 47 slides in the through groove 450. The control column 47 drives the movable plate 42 to slide on the fixed column 41. After the docking post 43 is separated from the docking hole 100, the upper shell 1 and the lower shell 2 can be separated. At the same time, the spring 44 is conducive to the resetting of the movable plate 42 and the docking post 43, thereby improving stability and being more practical.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
