[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 and Figure 4 The utility model provides an embodiment: a highly sealed waterproof connector housing structure, including a connector housing 1, a fixing ring 3 15 is fixedly connected to one side of the connector housing 1, a rubber ring 16 is fixedly connected to the inner wall of the fixing ring 3 15, a plurality of telescopic columns 17 are fixedly connected to the inside of the rubber ring 16, one end of the telescopic columns 17 are fixedly connected to an arc-shaped connecting plate 3 19, the outer wall of the telescopic columns 17 are provided with a spring 2 18, one side of the spring 2 18 is fixedly connected to the outer wall of the arc-shaped connecting plate 3 19, the other side of the spring 2 18 is fixedly connected to the outer wall of the telescopic column 17, one side of the arc-shaped connecting plate 3 19 is fixedly connected to a slider 20, the outer wall of the slider 20 is slidably connected to a fixing ring 4 22, one side of the fixing ring 4 22 is fixedly connected to the inner wall of the fixing ring 3 15, and one side of the slider 20 is fixedly connected to a sealing ring 3 21, a splicing component is provided on one side of the connector housing 1, and the splicing component is used for splicing equipment.

[0033] Specifically, during use of the highly sealed waterproof connector housing, one end of the connector is moved into the connector housing. During this process, the outer wall of the connector passes through sealing ring 3 21, which is squeezed and deformed to a certain extent. This deformation causes sealing ring 3 21 to be squeezed inward, thereby pushing slider 20 to slide inside fixed ring 4 22. The movement of slider 20 causes telescopic column 17 to perform a corresponding contraction movement. At the same time, the movement of slider 20 also causes spring 2 18 to squeeze. When subjected to the squeezing force, spring 2 18 generates a reaction force. This reaction force pushes sealing ring 3 21 to squeeze the outer wall of the connector more tightly, thereby enhancing the sealing performance of the device. This solves the problem of loose fit between the sealing component and the connector of traditional devices, which affects the performance of the sealing component, and enhances the sealing performance of the device.

[0034] Reference Figure 2 and Figure 3The splicing assembly includes an arc-shaped connecting block 6, one side of which is arranged on the outer wall of the connector housing 1, a fixing ring 3 is fixedly connected to the inner wall of the connector housing 1, a connector housing 2 is arranged on the outer wall of the connector housing 1, a sealing ring 4 is fixedly connected to the outer wall of the fixing ring 3, a sealing ring 2 is arranged on one side of the sealing ring 4, the outer wall of the sealing ring 2 5 is fixedly connected to the inner wall of the connector housing 2, and one side of the fixing ring 3 is fixedly connected to the outer walls of multiple arc-shaped connecting blocks 6, one side of the arc-shaped connecting block 6 is provided with an arc-shaped connecting plate 8, and the other side of the arc-shaped connecting block 6 is provided with an arc-shaped connecting plate 2 9, an arc-shaped connecting plate A spring ball 10 is fixedly connected to the inside of the arc-shaped connecting plate 18 and the arc-shaped connecting plate 29, and a fixing plate 2 13 is fixedly connected to the outer walls of the arc-shaped connecting plate 18 and the arc-shaped connecting plate 29. The inside of the arc-shaped connecting plate 18 is rotatably connected to the rotating shaft 11, and the outer wall of the rotating shaft 11 is rotatably connected to the inside of the arc-shaped connecting plate 29. The two ends of the rotating shaft 11 are fixedly connected to the fixing plate 12, and one side of the fixing plate 12 is fixedly connected to multiple springs 14, and one side of the spring 14 is fixedly connected to the outer wall of the fixing plate 2 13. One side of the fixing plate 12 is fixedly connected to a fixing ring 2 7, and the outer wall of the fixing ring 2 7 is fixedly connected to the inner wall of the connector housing 2 2.

[0035] Specifically, during the equipment connection and assembly process, the connector housing 1 is moved toward the connector housing 2, and at the same time, the outer wall of the fixing ring 3 slides on the inner wall of the connector housing 2. When one side of the fixing ring 3 moves to the outer wall of the arc-shaped connecting plate 18 and the arc-shaped connecting plate 29, the two arc-shaped connecting plates will be squeezed by the arc surface of the outer wall of the fixing ring 27. Due to this squeezing force, the arc-shaped connecting plate 18 and the arc-shaped connecting plate 29 will rotate around the rotating shaft 11. During the rotation process, the arc-shaped connecting plate 18 and the arc-shaped connecting plate 29 drive the spring 14 to generate squeezing force through the fixing plate 2 13. When the fixing ring 27 is aligned with the arc-shaped connecting plate 18 and the arc-shaped connecting plate When the inner walls of the two 9 overlap, the spring 14 will generate a rebound force. This rebound force will cause the arc-shaped connecting plate 18 and the arc-shaped connecting plate 29 to engage the fixing ring 27. At this time, the hole on the outer wall of the fixing ring 27 will move to the outer wall position of the spring clamping ball 10. The spring action on one side of the spring clamping ball 10 will move the fixing ring 27 to the hole on the outer wall of the telescopic column 17, thereby enhancing the stability of the connection between the connector housing 1 and the connector housing 2, solving the problem that traditional equipment needs to use tools to screw the threads on the two connectors together during the connection process, which is more troublesome to install. It improves the equipment connection efficiency and enhances the stability of the equipment connection.

[0036] Working principle: During the use of the highly sealed waterproof connector housing, one end of the connector is moved to the inside of the connector housing 1. When the outer wall of the connector passes through the inner wall of the sealing ring 3 21, the sealing ring 3 21 will be deformed, thereby pushing the slider 20 to slide inside the fixed ring 4 22. While the slider 20 moves, it will drive the telescopic column 17 to contract through the arc-shaped connecting plate 3 19, and at the same time drive the spring 2 18 to squeeze. When the spring 2 18 is subjected to the squeezing force, it will generate a reaction force, thereby pushing the sealing ring 3 21 to squeeze the outer wall of the connector, thereby enhancing the sealing of the equipment. During the connection and assembly of the equipment, the connector housing 1 is moved toward the side of the connector housing 2, and the outer wall of the fixing ring 3 slides on the inner wall of the connector housing 2. When the fixing ring 3 on one side is When the fixed ring 27 moves to the outer wall of the arc-shaped connecting plate 18 and the arc-shaped connecting plate 29, the arc-shaped connecting plate 18 and the arc-shaped connecting plate 29 are squeezed by the arc surface of the outer wall of the fixed ring 27, thereby rotating with the rotating shaft 11 as the center of the circle. While the arc-shaped connecting plate 18 and the arc-shaped connecting plate 29 rotate, the spring 14 is driven by the fixed plate 213 to generate an extrusion force. When the fixed ring 27 is connected and overlapped with the inner walls of the arc-shaped connecting plate 18 and the arc-shaped connecting plate 29, the spring 14 generates a rebound force, thereby engaging the fixed ring 27 through the arc-shaped connecting plate 18 and the arc-shaped connecting plate 29. At this time, the hole on the outer wall of the fixed ring 27 moves to the outer wall of the spring clamping ball 10, and the spring on one side of the spring clamping ball 10 is used to move it to the hole on the outer wall of the telescopic column 17, thereby enhancing the stability of the connection between the connector housing 1 and the connector housing 22.
