Description

Technical Field

[0001] This utility model relates to the field of cable wiring technology, specifically to an outdoor waterproof sealing connector. Background Technology

[0002] A cable gland, technically known as a waterproof cable connector or cable entry device, is a key component widely used in power, communication, and automation equipment. Its main function is to safely and securely introduce and fix cables to the interface of equipment (such as junction boxes and control boxes), while forming an effective seal to prevent external media such as moisture, dust, and humidity from intruding into the equipment, ensuring the reliability of electrical connections and the safe operation of the equipment. However, the rubber plugs inside current cable glands have fixed specifications and dimensions, only capable of sealing cables of a certain diameter. When installing cables of other diameters, gaps will exist, allowing rainwater to enter. Utility Model Content

A first half end 6 is fixedly connected to the right end surface of the threaded cap 5. A second half end 15 is snapped onto one side of the first half end 6. An inflatable sealing sleeve 7 is inserted inside the first half end 6. One end of the inflatable sealing sleeve 7 is inserted into the inside of the right end of the threaded connector 1. A pipe 8 is fixedly connected to the air port at the right end of the inflatable sealing sleeve 7. A through-hole half-pipe groove 20 is opened on the surface of both the first half end 6 and the second half end 15. One end of the pipe 8 passes through the two half-pipe grooves 20 and is located outside the first half end 6 and the second half end 15. A switch valve 9 is fixedly connected to one end of the pipe 8. A threaded end 10 is fixedly connected to one end of the switch valve 9.

[0015] An internally threaded tube head 13 is fixedly connected to the port of the piston cylinder 11. The inner side of the internally threaded tube head 13 is threadedly connected to the outer side of the threaded end 10. A piston column 12 is slidably connected inside the piston cylinder 11. One end of the piston column 12 and located inside the piston cylinder 11 is fixedly connected to a piston that fits against the inner wall of the piston cylinder 11. The other end of the piston column 12 extends to the outer side of the piston cylinder 11. Gas sufficient to satisfy the expansion of the inflatable sealing sleeve 7 to seal the smallest diameter cable to which it is adapted is stored inside the piston cylinder 11.

[0016] A barometer 14 is fixedly connected to the top of the internally threaded pipe head 13. The detection end of the barometer 14 extends into the internally threaded pipe head 13, and the barometer 14 is located behind the threaded end 10. The barometer 14 is used to detect and display the air pressure inside the inflatable sealing sleeve 7.

[0017] An inflatable flexible airtight sealing rubber plug 3 is fitted on the outer side of the left end of the threaded connector 1. A nut 4 is threadedly connected to the outer side of the left end of the threaded connector 1. The threaded connector 1 is installed on the wire hole of the outdoor junction box through the nut 4, the inflatable flexible airtight sealing rubber plug 3, and the limiting seat 2.

[0018] The top and bottom of the first half end 6 are fixedly connected with snap-fit ​​seats 17, and the top of the second half end 15 and one side of the snap-fit ​​seat 17 are fixedly connected with snap-fit ​​bodies 16. The second half end 15 is installed on the first half end 6 by snapping the snap-fit ​​body 16 with the snap-fit ​​seat 17.

[0019] One end of the snap-fit ​​body 16 is snapped into the snap-fit ​​seat 17. A handle is fixedly connected to one side of the second half end 15. Sealing grooves 19 are opened at both ends of the first half end 6. Plugs 18 are fixedly connected to both ends of the second half end 15. One end of each plug 18 extends into the sealing groove 19 and cooperates with the sealing gasket inside the sealing groove 19. The handle makes it easy to pull the second half end 15 to separate from the first half end 6.

[0020] In summary, when using this outdoor waterproof sealing connector, the inflatable flexible airtight sealing rubber plug 3 is placed on the outer side of the left end of the threaded connector 1. Then, one end of the threaded connector 1 is inserted into the outdoor junction box through the cable hole. Next, the nut 4 is screwed onto the outer side of the end of the threaded connector 1 that extends into the outdoor junction box, thus installing the threaded connector 1 onto the junction box. Then, one end of the cable passes through the first half-end 6, the second half-end 15, and the through hole in the middle of the inflatable sealing sleeve 7, then through the threaded connector 1 and out into the outdoor junction box. Finally, the threaded cap 5 is screwed onto the outer side of the right end of the threaded connector 1 to achieve an airtight seal. One end of the sleeve 7 is inserted into the right end of the threaded connector 1. Then, the internal threaded tube head 13 is screwed onto the outside of the right end of the threaded end 10. Then, the piston column 12 is pushed, causing the piston column 12 to push the piston and squeeze the gas inside the piston cylinder 11 into the internal threaded tube head 13. Then, the gas enters the threaded end 10, the switch valve 9, and the pipeline 8 through the internal threaded tube head 13. It then enters the inflation sealing sleeve 7 through the pipeline 8, causing the inflation sealing sleeve 7 to expand. This causes the inner wall of the inflation sealing sleeve 7 to contact the outer surface of the cable for sealing. Then, the switch valve 9 is manually closed. Next, the internal threaded tube head 13 is unscrewed from the outside of the threaded end 10. When it is necessary to replace the inflatable sealing sleeve 7, unscrew the threaded cap 5 to the outside of the right end of the threaded connector 1, and then pull the second half end 15 by the handle on the side of the second half end 15, so that the second half end 15 drives one end of the snap fastener 16 to be pulled out from the inside of the snap fastener seat 17. Remove the second half end 15 from one side of the first half end 6, so that the pipe 8 can be taken out from the inside of the half pipe groove 20. Take out the inflatable sealing sleeve 7, and then take out the new inflatable sealing sleeve 7. Then place the pipe 8 inside the half pipe groove 20 on the first half end 6, and then place the second half end 15 on one side of the first half end 6. Then the user presses the second half end 15, so that one end of the snap fastener 16 on the outside of the second half end 15 is snapped into the inside of the snap fastener seat 17, and the position of the second half end 15 is fixed.
