Description

Technical Field

[0001] This utility model relates to the field of cable junction box technology, specifically to a cable junction box wiring device. Background Technology

[0002] Cable junction boxes are used only for cable splitting. Their main function is to split or transfer cables. However, cable junction boxes require cable routing devices to operate.

[0003] Chinese patent (authorization announcement number: CN218976319U, authorization announcement date: 2023.05.05) proposes a cable distribution box wiring structure. In this utility model, the plug is inserted into the inside of the slot, so that the wiring tube can be fixed on both sides of the wiring frame according to the different cable layout spacing. Rotating the wiring tube causes the screw to pass through the plug and extend into the inside of the limiting hole, which greatly improves the stability of the plug when it is inside the slot, and thus improves the stability of the wiring tube after limiting the cable.

[0004] Cable junction boxes, as key equipment for cable splitting and transfer, play an important role in power transmission systems. However, in actual operation, many cable junction boxes lack an effective cable routing structure, resulting in messy and disorganized wiring. Although the aforementioned junction boxes use cable routing conduits to organize the wiring, these conduits are difficult to adapt to cables of different diameters, and the cables are prone to slipping out of the conduits. Furthermore, during later maintenance, the conduits need to be cut, increasing the difficulty of maintenance. Therefore, we propose a cable routing device for cable junction boxes.

[0029] When using this cable distribution box wiring device, after the cable enters through the inlet hole 4 on the bottom side of the box 1, it can be placed in the wiring groove 42 on the front and rear sides of the wiring box 6. The semi-circular sleeve 17 is installed with the wiring groove 42 by the quick-installation component to initially limit the cable position. Then, the clamping component inside the wiring box 6 drives the clamping block 33 to slide on the slide groove 22, so that the clamping block 33 clamps the cable and achieves a stable fixation of the cable. The wiring box 6 is installed on the U-shaped fixing plate 12 on the rear side of the box 1 through the fixing component, and the overall cable wiring operation is completed.

[0030] The clamping assembly includes a lifting plate 23, which is located inside the cable box 6.

[0032] The extrusion mechanism includes a fixed plate 36. Telescopic rods 34 are fixedly connected to the four corners of the fixed plate 36 near the top clamping block 33. The other end of each telescopic rod 34 is fixedly connected to the inner wall of the cable box 6, and a spring 35 is fitted onto each telescopic rod 34. An extrusion protrusion 37 is fixedly connected to the side of the fixed plate 36 away from the top clamping block 33.

A sliding rod 39 is fixedly connected to the side of the top clamping block 33 near the fixed plate 36. The other end of the sliding rod 39 slides into the interior of the sliding tube 38 and is fixedly connected to a limiting plate 40. A spring 41 is installed inside the sliding tube 38. The two sides of the limiting plate 40 abut against one end of the spring 41 and the inner wall of the sliding tube 38, respectively.

[0033] When the clamping assembly is working, the lifting plate 23 is located inside the cable box 6. The bottom ends of the telescopic rods 25 on the left and right sides of its bottom are fixed to the inner wall of the cable box 6. Springs 26 are fitted on the telescopic rods 25. The top end of the sliding rod 11 in the middle of the top side slides out of the top side of the cable box 6. When the sliding rod 11 is operated to move the lifting plate 23 up and down, the telescopic rods 25 and springs 26 extend and retract accordingly. Since the telescopic rod 34 on the side of the fixed plate 36 near the clamping block 33 is connected to the inner wall of the cable box 6 and fitted with springs 35, the pressing protrusion 37 on the side away from the clamping block 33... The top inclined surface abuts against the bottom inclined surface of the pressing protrusion 32. The sliding tube 38 of the fixed plate 36 is slidably connected to the sliding rod 39 of the clamping block 33. The spring 41 inside the sliding tube 38 abuts against the limiting plate 40 at the end of the sliding rod 39. As the pressing protrusion 32 on the bottom side of the lifting plate 23 continuously squeezes the protrusion 37, the clamping block 33 slides. After clamping is completed, the hook 27 at the bottom end of the connecting rod 24 on the bottom side of the lifting plate 23 cooperates with the hook 31 on the top side of the sliding I-beam 29 on the sliding groove 28 to lock the lifting plate 23.

[0034] The fixing assembly includes two sets of T-shaped connecting plates 14, which are fixedly connected to the left and right sides of the cable box 6 respectively. Several fixing holes 13 are provided through the upper and lower sides of the U-shaped fixing plate 12. Threaded holes 15 are provided through the upper and lower sides of the T-shaped connecting plate 14. Bolts 16 are threaded through the threaded holes 15, and the bolts 16 are also provided through the fixing holes 13.

[0035] When the fixing assembly is in operation, the two sets of T-shaped connecting plates 14 are fixed on the left and right sides of the cable box 6 respectively. Several fixing holes 13 are opened through the upper and lower sides of the U-shaped fixing plate 12, and threaded holes 15 are opened through the upper and lower sides of the T-shaped connecting plate 14. Bolts 16 are threaded through the threaded holes 15 and simultaneously through the fixing holes 13. The T-shaped connecting plate 14 and the U-shaped fixing plate 12 are fixed by the bolts 16, thereby realizing the installation and fixing of the cable box 6 on the U-shaped fixing plate 12.

[0036] The quick-installation assembly includes two sets of limiting plates 19, which are fixedly connected to the top of the left and right sides of the semicircular sleeve 17 respectively. The left and right sides of the cable tray 42 are provided with slots 18. The left and right sides of the inner wall of the semicircular sleeve 17 are fixedly connected with plug rods 20, which are slidably inserted into the slots 18.

[0037] When the quick-installation component is in operation, slots 18 are opened on the left and right sides of the cable tray 42, and plug rods 20 are fixed on the left and right sides of the inner wall of the semi-circular sleeve 17. The plug rods 20 are slidably inserted into the slots 18 to realize the quick installation and disassembly of the semi-circular sleeve 17 and the cable tray 42. Two sets of limiting plates 19 are fixed on the top of the left and right sides of the semi-circular sleeve 17 respectively. The limiting plates 19 make it easy to slide the semi-circular sleeve 17 by hand.

[0038] Several ventilation holes 5 are provided through the bottom of both the left and right sides of the box 1. A semi-circular tube 7 is fixedly connected to the ventilation hole 5. A ventilation opening 8 is provided on the bottom side of the semi-circular tube 7. A filter plate 9 is fixedly connected inside the ventilation opening 8. Outside air enters the box 1 through the ventilation hole 5 after being filtered by the ventilation opening 8 and the filter plate 9. At the same time, the filter plate 9 can block dust and other impurities from entering, so as to achieve ventilation and dust prevention of the box 1.

[0039] A limiting plate 21 is fixedly sleeved on the sliding rod 11. The top side of the limiting plate 21 abuts against the inner top side of the cable box 6. The limiting plate 21 restricts the sliding range of the sliding rod 11 and prevents the sliding rod 11 from sliding out of the cable box 6 excessively.

[0040] The bottom side of the I-beam 29 is provided with several anti-slip grooves 30. The anti-slip grooves 30 can increase the friction between the I-beam 29 and the operator's hand, making it easier for the operator to apply force when sliding the I-beam 29 and preventing slippage.

[0041] Several heat dissipation fins 10 are fixedly connected to the rear side of the enclosure 1. The heat dissipation fins 10 can increase the contact area between the enclosure 1 and the outside world, accelerate the dissipation of heat from the inside of the enclosure 1 to the outside world, and play an auxiliary role in heat dissipation.

[0042] Working principle: When using this cable distribution box wiring device, after the cable enters through the inlet hole 4 on the bottom side of the box 1, it can be placed in the wiring groove 42 on the front and rear sides of the wiring box 6. The wiring groove 42 has slots 18 on the left and right sides. The inner wall of the semi-circular sleeve 17 is fixed with plug rods 20 on the left and right sides. The plug rods 20 are slidably inserted into the slots 18 to realize the quick installation of the semi-circular sleeve 17 and the wiring groove 42, and to initially limit the cable.

[0043] Since the lifting plate 23 is located inside the cable box 6, the bottom ends of the telescopic rods 25 on its left and right sides are fixed to the inner wall of the cable box 6. A spring 26 is fitted onto the telescopic rod 25. The top end of the sliding rod 11 in the middle of the top side slides out of the top side of the cable box 6. When the sliding rod 11 is operated to move the lifting plate 23 up and down, the telescopic rods 25 and springs 26 extend and retract accordingly. Because the telescopic rod 34 on the side of the fixed plate 36 near the clamping block 33 is connected to the inner wall of the cable box 6 and fitted with a spring 35, the top slope of the pressing protrusion 37 on the side away from the clamping block 33 is connected to the bottom slope of the pressing protrusion 32. The sliding tube 38 of the fixed plate 36 is slidably connected to the sliding rod 39 of the top clamping block 33. The spring 41 inside the sliding tube 38 abuts against the limiting plate 40 at the end of the sliding rod 39. When the pressing protrusion 32 on the bottom side of the lifting plate 23 continuously squeezes the protrusion 37, the top clamping block 33 slides, so that the top clamping block 33 clamps the cable, thus achieving a stable fixation of the cable. After clamping is completed, the hook 27 at the bottom end of the connecting rod 24 on the bottom side of the lifting plate 23 cooperates with the hook 31 on the top side of the sliding I-beam 29 on the slide groove 28 to lock the lifting plate 23.

[0044] Since the two sets of T-shaped connecting plates 14 are fixed on the left and right sides of the cable box 6 respectively, and the upper and lower sides of the U-shaped fixing plate 12 have several fixing holes 13, and the upper and lower sides of the T-shaped connecting plate 14 have threaded holes 15, the bolts 16 are threaded through the threaded holes 15 and simultaneously through the fixing holes 13. The T-shaped connecting plate 14 and the U-shaped fixing plate 12 are fixed by the bolts 16, thereby realizing the installation and fixing of the cable box 6 on the U-shaped fixing plate 12, and completing the cable routing operation.
