Description

Technical Field

[0001] The invention relates to the technical field of cable installation, and in particular to a cable junction box. Background Art

[0002] The junction box is a junction device that provides cable termination and jumpering for the trunk layer cables and the distribution layer cables. It must be waterproof and dustproof, insect and rodent-proof, and have strong resistance to impact damage to ensure the normal operation of the equipment in the box.

[0003] In the prior art, there is a cable branch box with temperature and humidity adjustment and automatic dust removal, which has a publication number of CN112736831B. The automatic dust cleaning structure is combined with the cleaning of dust on the inner wall of the box, while continuous filtering and cleaning is performed at both the air inlet and outlet ends. This facilitates the removal of impurities and dust inside the box and the filtration of impurities in the air. At the same time, the box is equipped with a closable, adjustable and replaceable adjustment cover structure, which can flexibly adapt to weather conditions. The box controls a constant temperature and humidity, which not only provides an excellent internal environment, but also prolongs the quality retention time of the main insulator and is more convenient for cable branching.

[0004] However, there are still some defects in the actual use process. Since the cable threading hole on the junction box lacks a sealing structure, after the cable is threaded, in order to ensure the waterproof and dustproof, insect and rodent-proof functions of the box body, it is necessary to seal the threading hole with foam glue.

A lower strip 12 is fixedly connected, a fastening groove 13 is provided at the top of the threading plate 3, a rotating rod 14 is rotatably connected to the inner side of the fastening groove 13, the other ends of the upper strip 11 and the lower strip 12 cross through the outer wall of the semicircular arc seat 9 and the inner side of the fastening groove 13, the rubber tube 8 is inserted between the upper strip 11, the lower strip 12 and the inner side of the semicircular arc seat 9, a pulling mechanism for pulling a plurality of upper strips 11 and lower strips 12 is provided on the inner side of the fastening groove 13, and the upper strip 11 and the lower strip 12 are staggered, which can squeeze the semicircular sealing ring 24 and the rubber tube 8 more tightly, the upper strip 11 and the lower strip 12 are made of high-strength cotton rope material, and the service life of the upper strip 11 and the lower strip 12 can be improved by using high-strength cotton yarn material; The pulling mechanism includes a pull rope 16, and a winding roller 15 is fixedly connected to the outer wall of the rotating rod 14 and the corresponding positions of the upper strip 11 and the lower strip 12. A plurality of pull ropes 16 are provided, and one end of the plurality of pull ropes 16 is fixedly connected to the side walls of the upper strip 11 and the lower strip 12 respectively, and the other ends of the pull ropes 16 are all wound around the winding roller 15, and the other ends of the pull ropes 16 are fixedly connected to the outer wall of the winding roller 15. A moving cavity 17 is opened inside the threading plate 3 and at a position corresponding to the rotating rod 14. A gear 18 is fixedly connected to the side wall of the moving cavity 17 through the side wall of the rotating rod 14, and a rack 19 meshing with the gear 18 is slidably connected to the bottom end of the moving cavity 17. An inspection plate 23 is bolted to the top of the fastening groove 13, and a screw 20 is threadedly connected to the front side of the threading plate 3 and at a position corresponding to the rack 19, a rotating block 21 is fixedly connected to the side wall of the screw 20, and the side wall of the screw 20 is rotatably connected to the side wall of the rack 19; When threading the cables in the junction box, first pass multiple cables through the bottom of the cabinet 1, and then pass multiple cables through the threading holes 7 in turn, and then the cables can be docked with the branch cables on the flange. After the docking is completed, the threading holes 7 can be blocked, and the screw 20 is driven to rotate by rotating the rotating block 21. Since the screw 20 is threadedly connected to the threading plate 3, the screw 20 will move backward in a spiral, thereby pushing the rack 19 to move in the moving cavity 17, and at the same time driving the meshing gear 18 to rotate, and then driving the rotating rod 14 and the winding roller 15 to rotate, so as to reel the draw rope 16 wound on the winding roller 15, and then the upper strip 11 and the lower strip 12 are pulled by the draw rope 16.

Finally, after the plugging is completed, the rotating block 21 can be loosened. Since the threaded connection between the screw 20 and the threading plate 3 has a certain self-locking property, the plugging effect of the threading hole 7 is ensured. When the cable is subsequently disassembled, the rotating block 21 is rotated in the reverse direction and the above operation is repeated in the reverse direction to release the locking and plugging of the cable, saving time and effort and improving the convenience of the device.

[0023] In order to improve the stability of the device during operation, a guide groove 22 is opened at the bottom end of the movable cavity 17, and a guide block 37 is fixedly connected to the bottom of the rack 19 and is slidably connected to the inner side of the guide groove 22.

[0025] In order to be able to seal the unused interior of the fixed frame 5, a plurality of top holes 27 are opened on the top of the threading plate 3. Through the setting of the top holes 27, the cylinder 28 can be stored and placed, thereby improving the convenience of the device. The inner sides of the plurality of top holes 27 are connected with cylinders 28. Through the setting of the cylinders 28, when sealing the threading holes 7, the cylinders 28 can be placed between the semicircular sealing rings 24, and then the unused interior of the fixed frame 5 can be sealed, thereby improving the practical performance of the device. A pair of buckle grooves 29 are opened on the top of the cylinders 28. Through the setting of the buckle grooves 29, it is convenient for the installer to pull the cylinder 28 out of the top holes 27, thereby improving the convenience of the device.

[0026] In order to be able to flexibly change the position of the threading plate 3 according to the threading position of the cable, the fixing mechanism includes an upper screw 30, and both sides of the bottom end of the inner wall of the cabinet 1 are fixedly connected with a U-shaped seat 31, and both sides of the outer wall of the threading plate 3 are fixedly connected with a fixing plate 32 adapted to the inner side of the U-shaped seat 31, and the fixing plate 32 is plugged into the inner side of the U-shaped seat 31. Four upper screws 30 are provided, and the four upper screws 30 are all threadedly connected to the top of the U-shaped seat 31 and the fixing plate 32; A top groove 33 is provided on the top of the cabinet 1, and mounting grooves 34 are provided on both sides of the inner wall of the top groove 33, and a top plate 35 is inserted between the mounting grooves 34. Four lower screws 36 are provided on the top of the cabinet 1, and the four lower screws 36 are threadedly connected to the cabinet 1 and the top of the top plate 35; When the threading position on the junction box needs to be changed according to the laying position of the cables in different positions, the upper screw 30 on the threading plate 3 can be unscrewed with a tool first, thereby releasing the position fixation of the fixing plate 32, and then the lower screw 36 on the top plate 35 can be unscrewed with a tool, and then the threading plate 3 and the top plate 35 can be pulled out in turn, and then the installation positions of the top plate 35 and the threading plate 3 can be swapped (it should be noted here that when installing the threading plate 3, the threading plate 3 can be installed in reverse to avoid excessive rainwater accumulation in the fixing frame 5 on rainy days), and finally the upper screw 30 and the lower screw 36 can be installed back with a tool.
