[0001] The utility model relates to the technical field of cable joints, in particular to a waterproof docking plug. Background Art

[0002] Waterproof cable butt plugs are used for quick cable connections and facilitate later disassembly for repair and replacement. They typically consist of a male and female connector, which interconnect to form a complete waterproof plug system. Widely used in electrical connections requiring waterproofing and moisture resistance, waterproof plugs ensure reliable and secure connections, preventing circuit failures and potential safety hazards caused by moisture and humidity.

[0003] A Chinese patent (publication number CN216818837U) discloses a five-core waterproof docking plug. The five-core waterproof docking plug uses a locking member composed of a male screw sleeve and a female screw sleeve and a wire clamp housing to clamp the cable, effectively improving the stability of the docking plug after connection and effectively preventing the male and female cores from separating after the cable is pulled.

[0004] However, the docking plug only relies on the locking piece composed of a male screw sleeve and a female screw sleeve to prevent the male core and the female core from separating, which causes the docking plug to easily loosen when affected by external force, making the cable docking unstable and unable to clamp the cable well, which easily leads to poor cable contact. Utility Model Content

[0005] To address the above problems, a waterproof docking plug is provided. By setting an anti-slip mechanism, the limit block is locked into the limit hole to prevent the plug from loosening, solving the problem that the docking plug is prone to loosening when affected by external force, making the cable docking unstable.

[0006] In order to solve the existing technical problems, the present invention provides the following technical solutions:

[0007] A waterproof docking plug includes a male connector and a female connector. The male connector has a threaded sleeve with a male screw sleeve, the female connector has a threaded sleeve with a female screw sleeve, the male connector has a male core, and the female connector has a female core that matches the male core at one end opposite to the male connector. The male connector is provided with an anti-slip mechanism, which includes an anti-slip component for preventing the female connector from falling off and an abutting component that can abut the anti-slip component.

[0008] Preferably, the anti-slip assembly includes an elastic part and a limit block, a mounting block is fixed on the female connector, the elastic part is arranged on the mounting block, a fixing block is fixed on the male connector, a slot for plugging and unplugging the elastic part is provided on the fixing block, a limit hole is provided on the top of the fixing block, and the limit block is arranged on the elastic part and adapted to the limit hole.

[0009] Preferably, the abutting assembly includes a spring and an abutting plate. The springs are symmetrically fixed inside the fixing blocks, the abutting plate is fixed on the top of the springs, and a plurality of rolling grooves are formed in the abutting plate. Each rolling groove is slidably fitted with a ball.

[0010] Preferably, a plurality of insertion posts are provided on the male core, and a plurality of positioning grooves are formed outside the male core.

[0011] Preferably, a plurality of insertion slots corresponding to the insertion posts one by one are formed in the female core, and a positioning block adapted to the positioning groove is fixedly provided on the female core.

[0012] Preferably, a sealing ring is provided inside the male core.

[0013] Preferably, a plurality of clamping claws are fixedly provided at the ends of the male connector and the female connector away from each other. The clamping claws are arranged in a circle, and a strip-shaped opening is formed between two adjacent clamping claws.

[0014] Preferably, tightening nuts are sleeved on the threads at the ends of the male connector and the female connector away from each other, and a plurality of anti-slip strips are provided on the tightening nuts.

[0015] The beneficial effects of the present utility model compared with the prior art are as follows:

[0016] By providing an anti-loosening mechanism, the present utility model achieves the effect of preventing the plug from loosening. After the male connector and the female connector are inserted, the elastic member is pressed, so that the elastic member is inserted into the fixing block through the insertion slot. The limiting block is clamped into the limiting hole by the elasticity of the elastic member itself. Then, the abutting plate is bounced up by the spring, so that the abutting plate abuts against the elastic member.

Specific embodiments

[0025] To further understand the features, technical means, specific purposes and functions achieved by the present utility model, the present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.

[0026] See Figures 1-7 As shown, a waterproof docking plug includes a male connector 100 and a female connector 200. A male screw sleeve 101 is threadedly sleeved on the male connector 100, and a female screw sleeve 201 is threadedly sleeved on the female connector 200. A male core 102 is provided on the male connector 100, and a female core 202 adapted to the male core 102 is provided at one end of the female connector 200 opposite to the male connector 100. An anti - detachment mechanism 300 is provided on the male connector 100. The anti - detachment mechanism 300 includes an anti - detachment component for preventing the female connector 200 from falling off and a abutting component capable of abutting and setting the anti - detachment component.

[0027] When it is necessary to dock two cables, use the male connector 100 to hold one of the cables tightly, then use the female connector 200 to hold the remaining cable tightly. Insert the male core 102 into the female core 202, tighten the male screw sleeve 101 and the female screw sleeve 201 to fix the male connector 100 and the female connector 200, realizing the docking of the two cables. Use the anti - detachment component to fix the male connector 100 and the female connector 200 again, and fix the anti - detachment component by the abutting component abutting the anti - detachment component.

[0028] By providing the male core 102 and the female core 202, the accuracy of the plug docking is effectively improved, and the working efficiency of the cable docking is improved. At the same time, by providing the anti-slip mechanism 300, the plug is prevented from slipping off, avoiding the plug from loosening after docking, making it impossible for the cables to contact normally, and greatly improving the stability and reliability of cable docking.

[0029] See also Figures 1-4 As shown, the anti-slip assembly includes an elastic member 302 and a limit block 303. A mounting block 301 is fixedly provided on the female connector 200, and the elastic member 302 is provided on the mounting block 301. A fixing block 304 is fixedly provided on the male connector 100. A slot 305 for plugging and unplugging the elastic member 302 is provided on the fixing block 304. A limit hole 306 is provided on the top of the fixing block 304. The limit block 303 is provided on the elastic member 302 and is adapted to the limit hole 306.

[0030] After the male connector 100 and the female connector 200 are plugged in, the elastic member 302 is pressed so that the elastic member 302 is inserted into the fixed block 304 through the slot 305. The elastic member 302 itself is used to snap the limit block 303 into the limit hole 306, solving the problem of how to prevent the plug from loosening.

[0031] See also Figures 3-4 As shown, the abutment assembly includes a spring 307 and an abutment plate 308. The spring 307 is symmetrically fixed in the fixed block 304, and the abutment plate 308 is fixed on the top of the spring 307. A plurality of rolling grooves are opened on the abutment plate 308, and a ball 309 is slidably fitted in each rolling groove.

[0032] When the elastic member 302 is inserted into the fixed block 304, the spring 307 is used to bounce the abutment plate 308 so that the abutment plate 308 abuts against the elastic member 302. A plurality of balls 309 are provided on the top of the abutment plate 308 to reduce friction, making it more convenient to insert and pull out the elastic member 302 and enhancing the flexibility of the abutment assembly. The abutment plate 308 is used to abut the elastic member 302, thereby improving the stability of the elastic member 302 and further enhancing the anti-detachment effect of the plug as a whole.

[0033] See also Figures 5-6 As shown, the male core 102 is provided with a plurality of plug-in posts 103, the outside of the male core 102 is provided with a plurality of positioning grooves 104, the female core 202 is provided with a plurality of plug-in grooves 204 corresponding one to one with the plug-in posts 103, and the female core 202 is fixed with a positioning block 203 adapted to the positioning groove 104.

[0034] When the male connector 100 needs to be plugged into the female connector 200, the plug-in post 103 is plugged into the plug-in slot 204 to form a current path, which facilitates electrical conduction between the two cables. At the same time, the positioning block 203 is snapped into the positioning slot 104 to position the female connector 200, preventing the female connector 200 from rotating and causing poor cable contact, thereby improving the accuracy and stability of cable docking.

[0035] See also Figure 5 As shown, a sealing ring 105 is provided in the male core 102 .

[0036] The sealing ring 105 is provided to achieve a sealing effect, thereby preventing water from entering the male core 102 and causing poor contact of the plug post 103, thereby improving the overall safety of the plug.

[0037] See also Figures 1-7 As shown, the male connector 100 and the female connector 200 are fixed with multiple clamping claws 402 at one end away from each other. The clamping claws 402 are arranged in a circle, and a strip opening 403 is formed between two adjacent clamping claws 402. The strip openings 403 are evenly distributed around the axis of the male connector 100.

[0038] The multiple clamping claws 402 provided at both ends are used to clamp the peripheral wall of the cable and hold the cable tightly, thereby sharing the axial pulling force on the male connector 100 and the female connector 200, preventing the cable from loosening due to axial pulling, and improving the stability of the cable docking.

[0039] See also Figures 1-7 As shown, the ends of the male connector 100 away from the female connector 200 are both threadedly sleeved with a locking nut 401 , and a plurality of anti-slip strips 404 are provided on the locking nut 401 .

[0040] The clamping claw 402 is contracted by the tightening nut 401 to hold the cable tightly and prevent it from loosening. The anti-slip strip 404 is provided to prevent slipping, so that the staff can better rotate the tightening nut 401 and improve the overall convenience of the plug.
