Description

Technical Field

[0001] This utility model relates to the field of junction boxes, and more specifically, it relates to a high-voltage cable junction box. Background Technology

[0002] Cable junction boxes are very common in power construction. A cable junction box is a device used to connect, branch, splice, and switch circuits of cable lines. Switches or other electrical equipment are also installed inside to ensure the normal operation of the power lines. Existing junction boxes are generally metal box structures with thin metal plates inside to support cables or electrical equipment. Depending on the line requirements, cable joints or electrical equipment installation locations may vary within the junction box. Existing junction boxes are not easily adjustable based on the placement of the internal metal plates, thus affecting cable connections, electrical equipment installation, and overall applicability. Furthermore, because the installation location of the junction box must be determined according to the line requirements, uneven or low-lying areas make stable installation difficult and can easily lead to water accumulation at the junction box location, affecting line safety.

[0009] The present invention is further configured such that the movable block has a rotating hole, and rotating columns are fixedly provided at both ends of the movable plate. The rotating hole and the rotating columns are rotatably connected. Both the rotating column and the movable block have connecting holes with threads, thereby facilitating the rotation of the movable plate.

[0014] Compared with the prior art, this utility model provides a high-voltage cable junction box, which has the following advantages:

[0015] This utility model features movable blocks inside the housing, with a movable plate positioned between two movable blocks. The movable plate is rotatably connected to the movable blocks. When equipment needs to be installed on the movable plate, rotating the movable plate keeps it horizontal, facilitating the installation of electrical equipment by the operator. Rotating the first threaded rod raises or lowers the movable blocks, thereby raising or lowering the movable plate and the equipment installed on it. This allows for easy adjustment of the installation position of the electrical equipment as needed, and facilitates adjustment of the entire junction box, improving its applicability.

[0016] This utility model, through the setting of a fixed structure on a movable plate and an extension plate, allows the mounting frame to be installed on the movable plate or extension plate after the cable connector is completed, according to the position of the cable, by fitting the mounting post with different mounting holes. Rotating the second threaded rod inside the mounting frame causes the two fixing plates to move closer or further apart, thereby fixing the fixing plates to the cable. This prevents the cable from changing position due to vibration or other external factors during daily use, thus preventing the connector from becoming loose and improving the protection effect of the junction box on the cable.

[0017] This utility model, by setting up a support structure, allows the junction box to be installed in uneven or low-lying locations. When the installation location is uneven, the extension length of each support block can be adjusted according to the actual situation to keep the box level. When the junction box is installed in a low-lying location, the different positioning holes on the support rods and the positioning holes on the collar can be matched to extend the height of the box from the ground, thereby reducing the impact of water accumulation in low-lying locations on the junction box.

[0032] Specifically, when using the junction box, high-voltage cables are introduced into the box 1 through different inlet holes 5 on the box body 1. When electrical equipment needs to be installed between the cables, the movable plate 3 is rotated by the cooperation of the rotating column 16 and the rotating hole 15 to keep the movable plate 3 horizontal. The operator installs the electrical equipment by connecting the mounting hole 20 on the movable plate 3 with the opening of the equipment itself with bolts. The movable plate 3 is then rotated to make it vertical. Bolts are inserted into the connection holes 17 on the movable block 14 and the rotating column 16 to fix the vertical state of the movable plate 3. The first threaded rod 12 is rotated, and through the threaded connection between the first threaded rod 12 and the movable block 14, the first threaded rod 12 is rotated. 2. The moving block 14 is raised or lowered, thereby raising or lowering the moving plate 3 and the equipment installed on the moving plate 3. The electrical equipment is moved to the positions of the two cables, and the cables are connected to the electrical equipment. After the two cables are connected in the junction box, the mounting frame 6 is installed on the moving plate 3 or the extension plate 4 according to the position of the cables through the cooperation of the mounting post 21 and different mounting holes 20. The mounting frame 6 is fixed by the threaded cooperation between the limiting piece 23 and the mounting post 21. The second threaded rod 22 set in the mounting frame 6 is rotated. Through the two threads with opposite directions set in the second threaded rod 22 and the threaded connection with the fixing piece 8, the two fixing pieces 8 are moved closer or further away from each other, thereby fixing the fixing pieces 8 to the cables and restricting the slight movement of the cables by the fixing pieces 8.

[0033] Please refer to Figure 1-5 As one embodiment of the installation of the housing 1: the support rod 10 is movably disposed in the collar 9, the collar 9 is fixedly disposed on the housing 1, the support block 11 is fixedly disposed with a threaded block 24, the threaded block 24 extends into the support rod 10 and is threadedly connected to the support rod 10, and both the collar 9 and the support rod 10 are provided with positioning holes 25, and the positioning holes 25 are provided with threads;

[0034] Specifically, when the installation position is uneven, the support block 11 is rotated, and the threaded connection between the threaded block 24 on the support block 11 and the support rod 10 is used to change the extension length of each support block 11 according to the actual situation, so that the box 1 remains horizontal. When the junction box is installed in a low-lying position, the bolts are inserted into the limiting holes through the cooperation between the different positioning holes 25 on the support rod 10 and the positioning holes 25 on the collar 9 to fix the support rod 10, thereby extending the height of the box 1 from the ground through the support rod 10.

[0035] In summary, when using it as a whole:

[0036] When the installation position is uneven, rotate the support block 11. Through the threaded connection between the threaded block 24 on the support block 11 and the support rod 10, the extension length of each support block 11 can be changed according to the actual situation, so that the box 1 remains horizontal. When the junction box is installed in a low-lying position, the bolts are inserted into the limiting holes through the cooperation between the different positioning holes 25 on the support rod 10 and the positioning holes 25 on the collar 9 to fix the support rod 10, thereby extending the height of the box 1 from the ground through the support rod 10.

[0037] When using the junction box, high-voltage cables are introduced into the box 1 through different inlet holes 5 on the box body 1. When electrical equipment needs to be installed between the cables, the movable plate 3 is rotated by the cooperation of the rotating column 16 and the rotating hole 15 to keep the movable plate 3 in a horizontal state. The operator installs the electrical equipment by connecting the mounting hole 20 on the movable plate 3 with the hole on the equipment itself with bolts. The movable plate 3 is then rotated to make it vertical. Bolts are inserted into the connection holes 17 on the movable block 14 and the rotating column 16 to fix the vertical state of the movable plate 3. The first threaded rod 12 is rotated and connected to the movable block 14 by threads. Rotating the first threaded rod 12 causes the movable block 14 to rise or fall, thereby causing the movable plate 3 and the equipment installed on the movable plate 3 to rise or fall, moving the electrical equipment to the positions of the two cables and connecting the cables to the electrical equipment.

[0038] After connecting the two cables in the junction box, the mounting frame 6 is installed on the movable plate 3 or extension plate 4 through the cooperation of the mounting post 21 and different mounting holes 20, according to the position of the cables. The mounting frame 6 is fixed by the threaded engagement of the limiting piece 23 with the mounting post 21. The second threaded rod 22 provided in the mounting frame 6 is rotated. Through the two threads with opposite directions provided on the second threaded rod 22 and the threaded connection with the fixing piece 8, the two fixing pieces 8 are driven to move closer or further away from each other, thereby fixing the fixing pieces 8 to the cable and restricting the slight movement of the cable.

[0039] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
