In addition, the sealing ring is usually arranged at the interface of the line, and the line will generate heat after being electrified, so the sealing ring will be affected by the heat generated by the line and thus accelerate the aging, resulting in a shorter service life of the waterproof connector as a whole.

[0004] Based on the above situation, the present application provides a connector with a function of preventing moisture from entering a socket, which has a long service life and good waterproof effect. SUMMARY

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0032] Embodiment 1

[0033] A connector with the function of preventing moisture from entering the plug, as shown in Figures 1-5 , comprises a connecting sleeve 1, a connecting plug 11, a moving frame 12, a first mounting plate frame 13, an isolation film 14, a second mounting plate frame 15, a clasp 16, a rotating frame 17, and a screw rod 18. The connecting plug 11 is inserted into the left side of the connecting sleeve 1. The first mounting plate frame 13 is fixedly connected to the right side of the connecting sleeve 1. The isolation film 14 is fixedly connected to the left side of the first mounting plate frame 13. The moving frame 12 is fixedly connected to the left end of the isolation film 14. The second mounting plate frame 15 is fixedly connected to the left side of the connecting plug 11. The moving frame 12 is in contact with the second mounting plate frame 15. The rotating frame 17 is rotationally connected to the outside of the second mounting plate frame 15 in a circumferential equidistant manner. The screw rod 18 is screwedly connected to the right side of the rotating frame 17. The clasp 16 is rotationally connected to the right side of the screw rod 18. The clasp 16 is in contact with the moving frame 12.

[0034] As shown in Figure 3 and Figure 4 , the left side of the moving frame 12 is fixedly connected with a sealing ring.

[0035] As shown in Figure 3 and Figure 4 , the isolation film 14 is made of polyurethane material.

[0036] When the worker needs to connect two lines together, first, the right end line is connected with the connecting sleeve 1, and the left end line is connected with the connecting plug 11, then the connecting sleeve 1 and the connecting plug 11 are inserted together to complete the connection between the two lines, then the circumferentially equidistantly distributed clamps 16, rotating frames 17 and screw rods 18 are all rotated away from the connecting plug 11, and the moving frame 12 is moved to the left to contact the second mounting plate frame 15, the isolation film 14 is stretched and wraps part of the connecting sleeve 1 and the connecting plug 11, then the circumferentially equidistantly distributed clamps 16, rotating frames 17 and screw rods 18 are reversely rotated to reset, and the clamp 16 hooks the right end of the moving frame 12, at this time, the screw rod 18 is forwardly rotated to drive the clamp 16 and the moving frame 12 to continue to move to the left, and the moving frame 12 is tightly attached to the second mounting plate frame 15, and because the left end of the moving frame 12 is fixedly connected with a sealing ring, the moving frame 12 and the second mounting plate frame 15 have good sealing property, so that the insertion port of the connecting sleeve 1 and the connecting plug 11 is wrapped and protected by the isolation film 14, thereby effectively preventing water from entering the insertion port, and preventing the isolation film 14 from rapidly aging due to heat generated when the lines are powered on, thereby improving the waterproof effect and service life of the connector, when the worker needs to disconnect the two lines, first, the screw rod 18 is reversely rotated to drive the clamp 16 to move to the right to reset, and then the circumferentially equidistantly distributed clamps 16, rotating frames 17 and screw rods 18 are all rotated away from the connecting plug 11, then the moving frame 12 is moved to the right to reset, and the connecting plug 11 is pulled out of the connecting sleeve 1.

[0037] Embodiment 2

[0038] On the basis of embodiment 1, as shown in Figure 6 and Figure 7 a sealing mechanism is further included, the sealing mechanism is arranged on the first mounting plate frame 13 and the second mounting plate frame 15, and includes rotating blocks 2, soft sleeves 21, tensioning ropes 22, gear wheels 23, limiting frames 24 and torsional springs 25, the two rotating blocks 2 are respectively rotatably connected to the right side of the first mounting plate frame 13 and the left side of the second mounting plate frame 15, the rotating block 2 is rotatably connected with the circumferentially equidistantly distributed limiting frames 24 inside, the torsional spring 25 is fixedly connected between the limiting frame 24 and the rotating block 2, the gear wheel 23 is fixedly connected to the first mounting plate frame 13 and the second mounting plate frame 15 outside, and the gear wheel 23 is extruded and matched with the adjacent limiting frame 24, the soft sleeve 21 is fixedly connected to the first mounting plate frame 13 and the second mounting plate frame 15 inside, and the tensioning rope 22 is wound outside the soft sleeve 21, one end of the tensioning rope 22 is fixedly connected with the adjacent rotating block 2, the other end of the right side tensioning rope 22 is fixedly connected with the first mounting plate frame 13, and the other end of the left side tensioning rope 22 is fixedly connected with the second mounting plate frame 15.

[0039] When the worker connects the right end wire with the connecting sleeve 1 and connects the left end wire with the connecting plug 11, the wire needs to pass through the soft sleeve 21 on the first mounting frame 13 or the second mounting frame 15 to be connected with the connecting sleeve 1 or the connecting plug 11, so at this time the worker can rotate the rotating block 2 clockwise, thereby driving the tensioning rope 22 to gradually tighten and wind on the soft sleeve 21, and the tightened tensioning rope 22 will extrude the soft sleeve 21 and make the soft sleeve 21 keep close to the wire, so as to ensure that the wire has good sealing between the connecting sleeve 1 and the connecting plug 11, so as to avoid water vapor entering the connector from the connection between the wire and the connecting sleeve 1 and the connecting plug 11, thereby improving the waterproof effect of the connector, and the circumferentially equidistantly distributed limiting frames 24 will rotate clockwise with the rotating block 2, and the limiting frames 24 will be intermittently extruded and contacted with the gear 23 when rotating clockwise, and the limiting frames 24 will rotate outward, and the torsional spring 25 will deform accordingly, when the limiting frames 24 rotate with the rotating block 2 to separate from the protrusions of the gear 23, the limiting frames 24 will rotate inward and reset under the action of the torsional spring 25 and be close to the recesses of the gear 23, and when the rotating block 2 wants to drive the limiting frames 24 to rotate counterclockwise, the gear 23 will hinder the rotation of the limiting frames 24, thereby avoiding the counterclockwise rotation of the rotating block 2 and the limiting frames 24 and causing the tensioning rope 22 to loosen, so as to ensure that the soft sleeve 21 always keeps close to the wire.

[0040] As shown in Figure 8 , it further comprises a close mechanism, the close mechanism is arranged on the first mounting frame 13, and the close mechanism comprises a pressing frame 3, a pressing ball 31 and an elastic rope 32, the circumferentially equidistantly distributed pressing frames 3 are all rotationally connected to the outside of the first mounting frame 13, the elastic rope 32 is fixedly connected between the pressing frame 3 and the moving frame 12, the equidistantly and uniformly distributed pressing balls 31 are fixedly connected to the middle of the elastic rope 32, and the pressing balls 31 are extrudedly matched with the isolation film 14.

[0041] As shown in Figure 8 , wherein the middle of the pressing frame 3 is provided with an arc surface.

[0042] When the worker moves the moving frame 12 to the left and makes it close to the second mounting frame 15, the moving frame 12 will pull the elastic rope 32 and make the elastic rope 32 gradually straighten, and the elastic rope 32 will pull the pressing frame 3 after gradually straightening, thereby making the circumferentially equidistantly distributed pressing frames 3 all rotate towards the direction of approaching the isolation film 14 and extrude the isolation film 14, and the pressing balls 31 on the straightened elastic rope 32 will also contact and extrude the isolation film 14, thereby making the isolation film 14 keep close to the connecting sleeve 1 and the connecting plug 11 as much as possible to reduce the gap, and also providing a certain degree of protection for the isolation film 14 by means of the elastic rope 32 and the pressing frame 3, so as to reduce the possibility of the isolation film 14 being scratched by external objects, and when the moving frame 12 moves to the right and resets, the elastic rope 32 will shrink and restore to the original state.

[0043] As shown in Figure 9 andFigure 10 As shown in the drawings, the device further comprises a separating mechanism, which is arranged on the rotating block 2 and comprises a placing block 4, an elastic clamping frame 41, a stabilizing column 42 and an elastic rope 43. The two placing blocks 4 are respectively fixedly connected to the left side and the right side of the two rotating blocks 2. The elastic clamping frame 41 is slidably connected to the outside of the placing block 4. The stabilizing column 42 is fixedly connected to the top of the elastic clamping frame 41. The elastic rope 43 is fixedly connected to the middle of the elastic clamping frame 41.

[0044] When the worker fixes the moving frame 12 by means of the clamping device 16, the worker can also take the elastic clamping frame 41, the stabilizing column 42 and the elastic rope 43 on the left and right sides from the placing block 4, and clamp the two elastic clamping frames 41 at appropriate positions of the connecting sleeve 1 or the connecting plug 11 according to needs. The elastic clamping frame 41 and the elastic rope 43 immediately contact and press the isolation film 14, so that the isolation film 14 at this part is tightly attached to the connecting sleeve 1 or the connecting plug 11. In this way, the isolation film 14 is segmented and cut off, so as to avoid that any part of the isolation film 14 is damaged to cause the entire isolation film 14 to lose the waterproof effect, thereby improving the waterproof effect and service life of the isolation film 14. When the worker needs to fix the connected line, the worker can also insert the stabilizing column 42 on the installed elastic clamping frame 41 into the soil, so as to fix the line, the connecting sleeve 1 and the connecting plug 11. When not needed, the worker can take the elastic clamping frame 41 and other components from the connecting sleeve 1 and the connecting plug 11 and reinstall them on the placing block 4.

[0045] As shown in the drawings, Figure 1 and Figure 11 The device further comprises a limiting mechanism, which is arranged on the placing block 4 and comprises a fixed plate 5 and a clamping ring 51. The fixed plate 5 is fixedly connected to the lower side of the placing block 4. The clamping ring 51 is fixedly connected to the side of the fixed plate 5 away from the placing block 4.

[0046] When the worker connects the right-end line with the connecting sleeve 1 and connects the left-end line with the connecting plug 11, the fixed plate 5 and the clamping ring 51 can guide and limit the line, so as to facilitate the worker to pass the line through the soft sleeve 21 and insert the line into the connecting sleeve 1 or the connecting plug 11. Meanwhile, the clamping ring 51 can also avoid the line from being bent and causing a gap between the line and the soft sleeve 21, so as to affect the sealing between the line and the soft sleeve 21.

[0047] It should be understood that the above description is only for exemplary purposes and does not mean to limit the present application. Those skilled in the art will understand that the variations of the present application will be included in the scope of the claims herein.
