[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4This utility model provides a technical solution: a connector housing with strong protective properties, including a connector housing 1 and a plug housing 5. The plug housing 5 is inserted into one side of the connector housing 1, and a connecting sleeve 3 is fitted onto the connector housing 1. A through hole is formed on the outer wall of the connecting sleeve 3, and a first sealing ring 7 and a second sealing ring 8 are provided on the inner wall of the through hole. A support screw 6 is threaded into the through hole. This structure, by setting the first sealing ring 7 and the second sealing ring 8, can improve the sealing performance at the connection between the support screw 6 and the connecting sleeve 3, preventing water from entering the interior of the connecting sleeve 3 and improving the waterproof performance of the connecting sleeve 3. The support screw 6 is evenly distributed about the connecting sleeve 3. The lines are symmetrically distributed vertically. One end of the support screw 6 is connected to a rotating shaft 9, and the bottom of the rotating shaft 9 is connected to the mounting block 2. This structure, by setting the rotating shaft 9, ensures that the mounting block 2 will not rotate during the rotation of the support screw 6, allowing the mounting block 2 to move longitudinally, thereby driving the sealing strip 4, the first limiting block 10, and the second limiting block 11 at the bottom of the mounting block 2 to rise and fall. The bottom of the mounting block 2 is provided with the first limiting block 10 and the second limiting block 11, which are located on both sides of the sealing strip 4. This structure, by setting the sealing strip 4, ensures that the sealing strip 4 is located in the gap between the connector housing 1 and the plug housing 5. This design effectively blocks gaps and achieves waterproofing. The height of the sealing strip 4 is greater than the height of the first limiting block 10 and the second limiting block 11, both of which are made of metal. This structure, by inserting the first limiting block 10 and the second limiting block 11 into the annular groove on the outer wall of the plug housing 5, serves as a limiting element, preventing the connector housing 1 and the plug housing 5 from being pulled apart. The outer wall of the plug housing 5 has an annular groove, which corresponds to the annular groove on the inner wall of the housing 1. One end of the sealing strip 4, the first limiting block 10, and the second limiting block 11 are all inserted into the annular groove on the outer wall of the plug housing 5. By setting the thickness of the sealing strip 4 to be greater than the thickness of the first limiting block 10 and the second limiting block 11, based on the deformation characteristics of the sealing strip 4, the sealing strip 4 is under pressure when the first limiting block 10 and the second limiting block 11 are in contact with the outer wall of the plug housing 5, thereby making the sealing strip 4 fit tightly with the outer wall of the plug housing 5 and improving the waterproof performance; the outer wall of the connecting sleeve 3 is connected to the support screw 6, the inner wall of the connector housing 1 is provided with an annular groove, the mounting block 2 is provided inside the annular groove, the bottom of the mounting block 2 is provided with the sealing strip 4, the top of the mounting block 2 is movably connected to the support screw 6, and one end of the support screw 6 passes through the connector housing 1 and is movably connected to the connecting sleeve 3.

[0023] Working principle: When using this highly protective connector housing, firstly, when the sealing strip 4, the first limiting block 10, and the second limiting block 11 are fully retracted into the annular groove on the inner wall of the connector housing 1, insert the plug housing 5 from one side of the connector housing 1. When the plug housing 5 is at the appropriate depth, the annular groove on the outer wall of the plug housing 5 corresponds to the annular groove on the inner wall of the connector housing 1. Then, rotate the support screw 6 on the outer wall of the connector housing 1, causing the support screw 6 to push the mounting block 2 longitudinally during rotation. During the descent of the mounting block 2, the bottom of the mounting block 2... The sealing strip 4, the first limiting block 10, and the second limiting block 11 are close to the plug housing 5. When the first limiting block 10 and the second limiting block 11 are in contact with the outer wall of the housing 5, the sealing strip 4 is tightly fitted in the annular groove on the outer wall of the housing 5 and fills the gap between the connector housing 1 and the plug housing 5, thereby improving waterproofness. When the connector housing 1 and the plug housing 5 are pulled by external force, the sealing strip 4, the first limiting block 10, and the second limiting block 11 can play a limiting and intercepting role in the groove on the outer wall of the plug housing 5, thereby preventing the connector housing 1 and the plug housing 5 from separating.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
