Description

Technical Field

[0001] The utility model relates to the technical field of cable connection, in particular to a cable inlet sealing device. Background Art

[0002] During the use of the distribution cabinet, electricians often need to connect extension cords to the distribution cabinet. When performing wiring operations, electricians generally insert the cables into the distribution cabinet through the cable entry slot of the distribution cabinet first, and then connect the cables. After the wiring is completed, nylon ties or electrical tapes need to be used to bundle the cables.

[0003] This method of cable threading will result in a large gap at the cable inlet of the distribution cabinet, allowing external dust and impurities to easily enter the distribution cabinet and react with the circuit, increasing the risk of equipment damage. Moreover, the cable body has a certain weight, and the cable connection alone can only bear the weight, so the load-bearing effect is limited and there is a risk of disconnection.

[0024] Refer to Figure 1-Figure 3 As shown, the present utility model provides a cable inlet sealing device, including a power distribution cabinet 1 and a cable 10. A plurality of inlets 2 are opened on the bottom surface of the power distribution cabinet 1. A plurality of sealing sleeves 6 are sleeved in each inlet 2, and the diameters of the plurality of sealing sleeves 6 are sleeved in sequence from large to small. An extrusion structure 3 for fixing it in the inlet 2 is provided on the outermost sealing sleeve 6. A plug rod 7 is detachably inserted into the innermost sealing sleeve 6, and the cable 10 is sleeved in one of the innermost sealing sleeves 6. A fixing ring 9 for winding the cable 10 is provided above each inlet 2, and a plurality of plug-in fixing parts 4 for fixing the angle of the fixing ring 9 are provided on the inner wall of the back plate of the power distribution cabinet 1.

[0025] Further, both ends of the plurality of sequentially sleeved sealing sleeves 6 are designed to be conical, and the sealing sleeve 6 is made of rubber, which can be more smooth when inserted into the inlet 2, and at the same time prevent foreign impurities from accumulating at the sealing sleeve 6. The rubber sealing sleeve 6 can have a deformation effect with a certain elasticity during disassembly and assembly, and can achieve a more fitting sealing effect.

[0026] Specifically, rubber rings 8 are fixedly connected to both ends of the inner walls of the plurality of sequentially sleeved sealing sleeves 6, which can improve the sealing effect between the plurality of sealing sleeves 6. At the same time, the rubber ring 8 on the innermost sealing sleeve 6 can abut against the surface of the plug rod 7 or the cable 10 to achieve a good sealing effect.

[0027] Refer to Figure 2As shown in the figure, the extrusion structure 3 includes a fixed sealing ring 3a fixedly connected to the end of the outermost sealing sleeve 6. The outer side of the outermost sealing sleeve 6 is threadedly connected with a movable sealing ring 3b. The opposite surfaces of the fixed sealing ring 3a and the movable sealing ring 3b are symmetrically tapered designs. And an auxiliary rotating plate 3c is fixedly connected to the outer side of the movable sealing ring 3b. When the sequentially sleeved sealing sleeves 6 are inserted into the cable inlet 2, at this time, the movable sealing ring 3b and the fixed sealing ring 3a are respectively located inside and outside the power distribution cabinet 1. Then rotate the movable sealing ring 3b so that it is threadedly connected with the outermost sealing sleeve 6, driving the movable sealing ring 3b and the fixed sealing ring 3a to approach each other, completing the sealing of the cable inlet 2. At the same time, the surfaces of the tapered movable sealing ring 3b and the fixed sealing ring 3a can achieve a good sealing effect, and the auxiliary rotating plate 3c can facilitate the rotation of the movable sealing ring 3b.

[0028] Referring to Figure 3 As shown in the figure, the plug-in fixing member 4 includes a U-shaped connecting frame 4a fixedly connected to the fixing ring 9.

The bolt connecting member 5 includes a bolt 5a rotatably connected to the middle of the closed end of the U-shaped connecting frame 4a. A bolt hole 5b threadedly connected to the bolt 5a is provided on the back plate of the power distribution cabinet 1. When the two plug rods 4b are inserted into the positioning holes 4c at appropriate positions, rotate the bolt 5a so that it is threadedly connected with the bolt hole 5b, completing the angle fixing of the fixing ring 9 and preventing it from falling off.

[0029] Specifically, a convex disk 11 is fixedly connected to the end of the plug rod 7, and the convex disk 11 can facilitate the pulling out of the plug rod 7.

[0030] With the above structure, in use, remove an appropriate number of the inner sealing sleeves 6 according to the diameter of the cable 10, then insert the cable 10 into the remaining sealing sleeves 6, and then insert the sealing sleeves 6 into the cable inlet 2 and fix them through the extrusion structure 3. At this time, the cable inlet 2 will be completely sealed. Then position the fixing ring 9 at an appropriate inclination angle through the plug-in fixing member 4, and then wind the upper side of the cable 10 around the fixing ring 9 in an S shape to complete the auxiliary fixing of the upper side load of the cable 10. Then connect the cable 10 to the equipment. At the same time, the cable inlet 2 without the cable 10 inserted is sealed by the plug rod 7.

[0031] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
