Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model. The experimental methods in the following embodiments are all conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0021] Example:

[0022] See also Figure 1 - Figure 4 A split plug connector includes a plug connector housing sub-end 1, a plug connector housing female end 2 is connected to the plug connector housing sub-end 1, a plug connector housing female end 2 is provided in the plug connector housing female end 2, the plug connector housing female end 2 is locked on the plug connector housing sub-end 1 through the plug locking accessory 3, and an elastic pressure component 4 is provided in the plug connector housing female end 2.

[0023] By means of the provided plug-in locking accessory 3, the female end 2 of the plug-in connector housing drives the positioning column 35 to slide in the sub-end 1 of the plug-in connector housing, so that the female end 2 of the plug-in connector housing is plugged into the sub-end 1 of the plug-in connector housing, and the positioning column 35 is aligned with the positioning groove 36, and then the positioning column 35 is pushed through the positioning groove 36 by the restoring force of the spring 32, so as to achieve the purpose of self-locking the sub-end 1 of the plug-in connector housing and the female end 2 of the plug-in connector housing, and prevent the female end 2 of the plug-in connector housing from being easily loosened with the sub-end 1 of the plug-in connector housing during long-term plugging and unplugging in the sub-end 1 of the plug-in connector housing, thereby causing the plug-in connector to be disconnected. The female end 2 of the connector housing is loosened from the sub-end 1 of the plug connector housing, and the use of the female end 2 of the plug connector housing is affected. The plug locking accessory 3 includes a spring groove 31 symmetrically arranged on the surface of the female end 2 of the plug connector housing, a spring 32 is arranged on the inner wall of the spring groove 31, a slide groove 33 is arranged on the inner wall of the spring groove 31, a slider 34 slides in the slide groove 33, and a positioning column 35 is arranged on the outer wall of the slider 34. The positioning column 35 slides linearly in the spring groove 31, and the other end of the spring 32 is connected to the positioning column 35. The inner wall of the sub-end 1 of the plug connector housing corresponding to the outer end of the positioning column 35 is provided with a positioning groove 36;

[0024] When in use, first press the positioning post 35 into the spring groove 31, so that the positioning post 35 drives the slider 34 to slide in the slide groove 33, and the slider 34 drives the positioning post 35 to slide from the positioning groove 36 into the spring groove 31. During the process of the positioning post 35 sliding into the spring groove 31, the inner end of the positioning post 35 continuously presses the spring 32 against the inner wall of the spring groove 31, causing the spring 32 to deform, until the positioning post 35 slides into the spring groove 31, thereby achieving the purpose of separating the plug connector housing sub-end 1 from the plug connector housing female end 2. When the plug connector housing female end 2 needs to be connected, the positioning post 35 is pressed into the spring groove 31 in the same way, and then the plug connector housing female end 2 is plugged into the plug connector housing sub-end 1. During the process of plugging the plug connector housing female end 2, it should be noted that The outer wall of the positioning column 35 is fitted with the inner wall of the plug connector shell sub-end 1, and the plug connector shell female end 2 drives the positioning column 35 to move in the plug connector shell sub-end 1 until the plug connector shell female end 2 is completely plugged into the plug connector shell sub-end 1. At this time, the positioning column 35 is aligned with the positioning groove 36, and the positioning column 35 penetrates the positioning groove 36 under the push of the restoring force of the spring 32, thereby achieving the purpose of self-locking the plug connector shell sub-end 1 and the plug connector shell female end 2, preventing the plug connector shell female end 2 from being plugged and unplugged for a long time in the plug connector shell sub-end 1, and easily loosening with the plug connector shell sub-end 1, thereby causing the plug connector shell female end 2 to loosen from the plug connector shell sub-end 1 and affecting the use of the plug connector shell female end 2.

[0025] The outer surface of the positioning post 35 is designed in an arc shape, and the outer surface of the positioning post 35 is provided with an anti-slip pattern, which can push the positioning post 35 to make the positioning post 35 slide out of the positioning groove 36 and slide to fit the inner wall of the sub-end 1 of the plug connector housing. At this time, the female end 2 of the plug connector housing is pulled again, so that the female end 2 of the plug connector housing drives the positioning post 35 from the position aligned with the positioning groove 36 to continuously slide to rub against the inner wall of the sub-end 1 of the plug connector housing, thereby achieving the purpose of quickly unlocking the female end 2 of the plug connector housing. The slider 34 is designed in a rectangular shape, and the slide groove 33 is provided as a through hole compatible with the slider 34. The slider 34 slides linearly in the slide groove 33, which can make the slider 34 fully fit with the slide groove 33, thereby effectively achieving the purpose of limiting the shaking of the positioning post 35, making the positioning post 35 slide more stably in the spring groove 31, and further improving the stability of the connection between the sub-end 1 of the plug connector housing and the female end 2 of the plug connector housing.

[0026] The elastic pressure-applying assembly 4 includes a movable groove 41 provided on the outer wall of the female end 2 of the plug connector housing, a gear 42 is rotatably connected to the middle of the movable groove 41, a brake disc 43 is provided on the outer wall of the female end 2 of the plug connector housing at the right end of the gear 42, the brake disc 43 penetrates the female end 2 of the plug connector housing and is connected to the right end of the gear 42, two groups of guide grooves 44 are symmetrically provided on the outer wall of the movable groove 41 on both sides of the gear 42, movable rods 45 are slidably provided in the guide grooves 44, the movable rods 45 are meshed with the gear 42, and the two groups of movable rods 45 slide in opposite directions in the guide grooves 44, two groups of auxiliary grooves 46 are staggered on the left surface of the female end 2 of the plug connector housing, connecting rods 47 are provided on the surface of the movable rods 45 in the auxiliary grooves 46, and push rods 48 are provided on the surface of the connecting rods 47 facing the positioning groove 36;

[0027] When in use, firstly rotate the brake disc 43, so that the brake disc 43 drives the gear 42 to rotate in the movable groove 41, and the gear 42 rotates, which drives the two sets of movable rods 45 to slide in the two sets of guide grooves 44 in opposite directions, and the two sets of movable rods 45 synchronously drive the two sets of connecting rods 47 to slide in the auxiliary grooves 46 in opposite directions, and then squeeze the positioning column 35 through the push rod 48 on the connecting rod 47, so that the positioning column 35 slides out of the positioning groove 36, and makes the surface of the positioning column 35 slide to fit with the inner wall of the sub-end 1 of the plug connector housing, and then push the plug connector housing to the plug connector housing. The sub-end 1 pulls the female end 2 of the plug connector shell from the outside, so that the female end 2 of the plug connector shell drives the outer wall of the positioning column 35 to fit with the inner wall of the sub-end 1 of the plug connector shell, and then rotates the brake disc 43, so that the brake disc 43 drives the push rod 48 to slide out of the positioning groove 36 through the gear 42 and the movable rod 45. At this time, the female end 2 of the plug connector shell is pulled out from the sub-end 1 of the plug connector shell, so as to achieve the purpose of quickly pulling out the female end 2 of the plug connector shell, effectively shortening the use time of unlocking the female end 2 of the plug connector shell, thereby making it convenient for the staff to use the connector.

[0028] The push rod 48 is provided with anti-skid teeth on the side surface facing the positioning column 35, and the anti-skid teeth on the push rod 48 mesh with the anti-skid patterns on the outer end surface of the movable rod 45, and the push rod 48 can fit with the surface of the positioning column 35 so that the push rod 48 pushes the positioning column 35 to slide out of the positioning groove 36 and slide into the spring groove 31, preventing the push rod 48 and the positioning column 35 from sliding friction when the push rod 48 pushes the positioning column 35, thereby causing the positioning column 35 and the outer wall of the push rod 48 to be greatly worn. The outer wall diameter of the push rod 48 is smaller than the outer wall diameter of the positioning column 35. The push rod 48 is designed to be cylindrical, which can enable the female end 2 of the plug connector housing to drive the outer wall of the positioning column 35 to slide on the sub-end 1 of the plug connector housing. The push rod 48 will be stuck in the positioning groove 36 with the movement of the female end 2 of the plug connector housing, resulting in the female end 2 of the plug connector housing being unable to be pulled out of the sub-end 1 of the plug connector housing.
