Description

Technical Field

[0001] This utility model relates to the field of power supply box technology, and in particular to a power supply box with a wire harness fixing structure. Background Technology

[0002] A power supply box typically refers to a device installed in equipment or a system to manage power input and distribute electrical energy. It plays a crucial role in electrical equipment, with main functions including power switching, overload protection, voltage regulation, and current limiting. Specifically, the operation and structure of a power supply box may vary depending on the type of equipment, application scenario, and manufacturer's design. Publication number CN214256105U discloses a power supply box including a base, a support plate, and a heat sink. The base includes a bottom plate, side plates, and baffles. The side plates are provided with abutments arranged in a parallel, spaced-apart configuration. One side of the support plate is inserted between the abutments. A wiring block is provided on the support plate. The heat sink has heat dissipation holes arranged at intervals along the heat sink and communicating with it. The heat sink includes a top cover connected to the side plates and an extension connected to the top cover. The extension is fixedly connected to the bottom plate, and the heat sink has an L-shaped structure covering the base. The aforementioned power supply box, by setting heat dissipation holes on the heat sink to ventilate and dissipate heat inside the base, ensures heat dissipation efficiency. Furthermore, by installing support plates inside the base to mount external power supplies, it increases the ventilation area, further improving heat dissipation efficiency and thus ensuring operational efficiency and preventing equipment damage. While this product improves the heat dissipation efficiency of the power supply box, it lacks a mechanism to secure the internal wiring harnesses. This leads to unstable electrical connections due to crossing or misalignment of different wiring harnesses, resulting in decreased equipment performance. Additionally, it makes it inconvenient for maintenance personnel to access and repair the wiring harnesses, increasing maintenance time and costs. Therefore, improvements are needed.

[0027] Example 2

[0028] Please see Figure 3 , 6A mounting frame 26 is fixedly installed on the side of the box body 1. A first extrusion plate 27 is slidably connected inside the mounting frame 26. A first limiting rod 28 is fixedly installed inside the mounting frame 26. A first limiting spring 29 is fixedly connected to the side of the first extrusion plate 27. One end of the first limiting spring 29 is fixedly connected to the inner wall of the mounting frame 26. A second extrusion plate 30 is slidably connected inside the mounting frame 26. A second limiting rod 31 is fixedly installed inside the mounting frame 26. A second limiting spring 32 is fixedly connected to the side of the second extrusion plate 30. One end of the second limiting spring 32 is fixedly connected to the inner wall of the mounting frame 26. A pull rod 33 is fixedly installed to ensure that the plug can be securely connected to the power interface 4, preventing the plug from accidentally falling off or loosening, thereby improving the stability and reliability of the connection. The first pressing plate 27 is slidably connected to the first limiting rod 28, the second pressing plate 30 is slidably connected to the second limiting rod 31, and the pull rod 33 is slidably connected to the mounting frame 26. Through the cooperation between the first limiting spring 29, the second limiting spring 32 and the first pressing plate 27, the second pressing plate 30, the first pressing plate 27 and the second pressing plate 30 simultaneously press the two sides of the power plug, thereby improving the stability between the plug and the power interface 4.

[0029] Working principle: In use, first, the wire harness enters the power supply box through the inlet 3. Then, the wire harness is placed between clamp 7 and clamp 11. Pressing down on the wire harness will cause it to snap into the space formed by clamp 7 and clamp 11. While pressing the wire harness, clamp 7 and clamp 11 will move to both sides. Sliding blocks 8 and 12 will slide inside the mounting plate 6. At the same time, sliding blocks 8 and 12 will slide on the surfaces of sliding rods 9 and 13 respectively, making clamp 7 and clamp 11 more stable during movement. When sliding blocks 8 and 12 move, they will squeeze the first spring 10 and the second spring 14. The pressure, generated by the reaction force of the first spring 10 and the second spring 14, causes the clamping plates 7 and 11 to tightly press the wire harness inside, thus fixing and securing the wire harness. The wire harness is then placed into the wire-clamping groove 16 of the wire-clamping block 15. The pressure plate 20 is then rotated, pressing the wire harness inside the wire-clamping groove 16. Simultaneously, the insert 21 on the lower surface of the pressure plate 20 slides into the insert sleeve 22. The rotating head 24 is then grasped and rotated, causing the fixing threaded rod 23 to screw into the insert 21, thus fixing and securing the pressure plate 20 and the wire-clamping block 15, thereby fixing and securing the wire harness inside the wire-clamping groove 16, preventing different wire harnesses from being placed inside the equipment. The wiring harness may cross or misalign, thus maintaining the stability of the electrical connection and avoiding equipment performance degradation or instability caused by wiring harness problems. It also makes it easier for maintenance personnel to identify, access, and handle the power harness, enabling them to quickly locate and repair problems, reducing maintenance time and costs. When the user connects the power plug to the power interface 4, they first pull the lever 33. The lever 33 slides inside the mounting frame 26, causing the second pressing plate 30 to slide inside the mounting frame 26. Simultaneously, the second pressing plate 30 slides on the surface of the second limit rod 31, making the second pressing plate 30 more stable during movement. The second limiting spring 32 will be compressed. At this time, the power plug is connected to the power interface 4. As it is inserted, the first pressing plate 27 will be tightly pressed against the side of the power plug under the action of the first limiting spring 29. After the power plug is connected to the power interface 4, the pull rod 33 is released. At this time, the second limiting spring 32 will return to its original position, so that the second pressing plate 30 will press against the side of the power plug. By pressing the power plug simultaneously with the first pressing plate 27 and the second pressing plate 30, it is ensured that the power plug can be securely connected in the power interface 4, preventing the power plug from accidentally falling off or loosening, thereby improving the stability and reliability of the equipment.
