Technical Field

[0001] This utility model relates to the field of transformer technology, specifically to a box-type transformer with a wire harness constraint structure. Background Technology

[0002] Prefab transformers (commonly referred to as "prefab transformers") integrate the traditional transformer design into a prefab enclosure, featuring small size, light weight, low noise, low loss, and high reliability. They are widely used in residential communities, commercial centers, light stations, airports, factories, mines, enterprises, hospitals, schools, and other locations. However, existing prefab transformers suffer from drawbacks in that the wiring harnesses inside the enclosure are difficult to restrain. This necessitates reorganizing the wiring harnesses during maintenance, wasting considerable time and reducing the overall effectiveness of the device. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a box-type transformer with a wire harness constraint structure, including a box body 1. A connecting frame 4 is installed inside the box body 1. A movable tube 13 is slidably connected to the upper surface of the connecting frame 4. A support plate 14 is installed on the outer surface of the movable tube 13. A movable rod 15 passes through the inside of the movable tube 13. By manipulating the movable rod 15 to move downwards along the movable tube 13, a blocking plate 21 moves downwards, causing a movable plate 20 to move downwards. Then, a connecting pin 16 passes through the movable tube 13 and presses against the movable rod 15. This makes it easier for operators to manipulate the components to fix the wire harness, preventing the wire harness inside the box from becoming tangled and requiring maintenance personnel to reorganize it. This reduces the number of times maintenance personnel need to reorganize the wiring and further enhances the strength of the components within the device. In terms of performance during operation, a connecting pin 16 is provided on the outer surface of the moving tube 13. One end of the connecting pin 16, which is inserted into the moving tube 13, abuts against the moving rod 15. A fixed frame 17 is installed on the lower surface of the connecting frame 4. An auxiliary rod 18 passes through the inside of the fixed frame 17. A second buffer spring 19 is installed inside the fixed frame 17. The outer surface of the auxiliary rod 18 passes through the second buffer spring 19. The inside of the fixed frame 17 is slidably connected to the moving piece 20. The top ends of the auxiliary rod 18 and the second buffer spring 19 are both installed on the lower surface of the moving piece 20. A blocking piece 21 is installed on the upper surface of the moving piece 20. A round hole is opened on the upper surface of the blocking piece 21. When the moving rod 15 moves downward, it can be inserted into the round hole. The outer surface of the blocking piece 21 passes through the lower surface of the connecting frame 4.

[0022] In this invention, to enhance the stability of the device, a baffle plate 2 is installed on the upper surface of the housing 1, a baffle door 3 is hinged to the front of the housing 1, a connecting plate 5 is slidably connected to the front of the connecting frame 4, and a fixing pin 6 passes through the outer side of the connecting frame 4. The fixing pin 6 is inserted into the connecting plate 5 through the connecting frame 4, and then rotated clockwise to fix the connecting plate 5 in place within the connecting frame 4. This ensures greater stability of the internal components during use, preventing loosening and further improving the stability of the components. To mitigate the impact of loosening on the normal operation of the device, and to facilitate operator control of the components for securing the device, a fixing pin 6 is threaded through the connecting frame 4 at one end and threaded into the connecting plate 5. A movable handle 7 is installed on the front of the connecting plate 5. A movable frame 8 passes through the lower surface of the connecting frame 4, and a support frame 9 is installed at the top of the movable frame 8. A first buffer spring 10 is installed inside the connecting frame 4, and a connecting frame 11 is installed at the inner end of the first buffer spring 10. A roller 12 is rotatably connected inside the connecting frame 11. The connecting frame 11 is slidably connected inside the connecting frame 4. There are four sets of connecting frames 11 to prevent components from becoming loose.

[0023] In use, open the blocking door 3 outwards, operate the moving handle 7 to slide the connecting plate 5 forward along the connecting frame 4 to remove it, insert the wire harness into the connecting frame 4, so that the roller 12 contacts the wire harness, push the roller 12 outwards, the roller 12 moves outwards and drives the connecting frame 11 to move outwards, the connecting frame 11 moves outwards and compresses the first buffer spring 10, the reaction force of the first buffer spring 10 fixes the wire harness, pull out the connecting pin 16, operate the moving rod 15 to move downwards along the moving tube 13, the moving rod 15 moves downwards and inserts into the blocking plate 21, so that the blocking plate 21 moves downwards and drives the moving plate 20 downwards. Move the movable piece 20 downward along the inside of the fixed frame 17. The downward movement of the movable piece 20 drives the auxiliary rod 18 downward. The downward movement of the movable piece 20 compresses the second buffer spring 19. The auxiliary rod 18 moves downward along the inside of the fixed frame 17. After the movement is complete, operate the connecting pin 16 to pass through the movable tube 13 and press against the movable rod 15. Pass the wire harness through the corresponding hole in the connecting frame 4. Operate the movable handle 7 to slide the connecting plate 5 along the connecting frame 4. Operate the fixing pin 6 to pass through the connecting frame 4 and insert it into the connecting plate 5. Then rotate the fixing pin 6 clockwise to fix the connecting plate 5 in the connecting frame 4. Finally, flip the blocking door 3 inward to close it.

[0024] In summary, this box-type transformer with a wire harness constraint structure allows the operator to manipulate the components to fix the wire harness by manipulating the moving rod 15 downward along the moving tube 13, causing the blocking plate 21 to move downward and driving the moving plate 20 downward. Then, the connecting pin 16 passes through the moving tube 13 and presses against the moving rod 15. This makes it easier for the operator to manipulate the components to fix the wire harness, preventing the wire harness inside the box from becoming tangled and requiring maintenance personnel to reorganize it. This reduces the number of times maintenance personnel need to reorganize the wiring and further enhances the effectiveness of the components in the device during operation.

[0025] This box-type transformer with a wire harness constraint structure can be fixed in place by manipulating the fixing pin 6 through the connecting frame 4 and inserting it into the connecting plate 5, and then rotating the fixing pin 6 clockwise to fix the connecting plate 5 into the connecting frame 4. This makes the components inside the device more stable during use, thereby preventing the components from becoming loose. This further improves the stability of the components during use, reduces the impact of loose components on the normal use of the device, and makes it easier for operators to manipulate the components to fix the device.
