Description

Technical Field

[0001] This utility model relates to the technical field of distribution box equipment, specifically a distribution box equipment that facilitates cable routing. Background Technology

[0002] Distribution boxes require the assembly of switching equipment, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or panel to form a low-voltage distribution box. During normal operation, the circuit can be connected or disconnected by manual or automatic switches. Distribution boxes are characterized by small size, easy installation, special technical performance, fixed location, unique configuration functions, no site restrictions, wide application, stable and reliable operation, high space utilization, small footprint and environmental protection effect.

[0003] However, existing distribution box equipment still has some problems in use:

[0004] For example, a distribution box with application number CN201820878718.4 includes a distribution box body, a top cover on the top of the distribution box body, extension plates fixed on the lower outer side of the top cover, a distribution box door connected to the inside side of the distribution box body via a pivot, an observation window on the outer surface of the distribution box door, a door handle on one side of the outer surface of the distribution box door, a first insect-proof net on one side of the distribution box body, and foot pads fixed to the bottom of the distribution box body;

[0005] In traditional distribution boxes, cables are often secured using cable ties. During wiring, cables are prone to tangling and crossing. In later maintenance, the messy wiring makes maintenance and troubleshooting extremely difficult. Maintenance personnel need to spend a lot of time sorting out the cables to accurately locate the fault point, which seriously affects maintenance efficiency, increases power outage time, and causes inconvenience to production and daily life.

[0006] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0007] To address the aforementioned issues, an innovative design was implemented based on the existing distribution box equipment. Utility Model Content

[0008] The purpose of this utility model is to provide a distribution box device that facilitates cable routing, in order to solve the problem mentioned in the background art that the cable fixing method in the distribution box is mostly through cable ties. During the wiring process, the cables are prone to tangling and crossing. In the later maintenance, the messy wiring brings great difficulties to maintenance and fault diagnosis. Maintenance personnel need to spend a lot of time sorting out the cables in order to accurately find the fault point, which seriously affects maintenance efficiency, increases power outage time, and causes inconvenience to production and life.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A power distribution box device for convenient cable routing includes a box body and a heat dissipation mechanism. The heat dissipation mechanism is provided at the top of the box body. A rainproof top plate is bolted to the outer end of the box body. Two sets of guide plates are symmetrically welded to the inner wall of the box body. Several heat dissipation holes are opened on both sides of the box body. A metal dustproof mesh is fixed to the inner side of the heat dissipation holes. A baffle is fixed to the outer side of the heat dissipation holes. Two sets of mounting brackets are fixed to the inner side of the box body. Several mounting holes are opened at both ends of the two sets of mounting brackets. Cable routing frames are installed on both sides of the two sets of mounting brackets. Several wire holes are opened on the surface of the cable routing frames. A spring is fixed to the inner side of the cable routing frames. A clamp is fixed to the other end of the spring. Two sets of clamps are symmetrically arranged along the cable routing frames. Several winding posts are arranged between the cable routing frames and the mounting brackets.

[0011] The above technical solution utilizes the springs and clamps on the cable tray to secure the cables with elastic clamping force, and combines this with winding posts to achieve classified winding of the cables. Simultaneously, the heat dissipation mechanism and the guide plate work together to form directional airflow, completing heat exchange and blocking dust through heat dissipation holes and a metal dustproof mesh. This improves wiring standardization and maintenance efficiency, avoids cable clutter, facilitates later maintenance, increases repair efficiency, shortens power outage time, and provides convenience for production and daily life. It also optimizes the heat dissipation path and enhances dustproof and waterproof performance, ensuring long-term stable operation of the equipment.

[0012] Preferably, the heat dissipation mechanism includes an inner dustproof net disposed at the top of the housing, an outer dustproof net disposed at the outer end of the housing, a cooling fan installed between the inner and outer dustproof nets, and fastening bolts passing through the four corners of the inner and outer dustproof nets.

[0013] The above technical solution uses a double-layer dustproof mesh, combining the inner and outer dustproof meshes to form a filtration barrier. When the cooling fan is running, a negative pressure difference is created inside and outside the enclosure, and the forced airflow flows through the electrical components after passing through the double filtration, achieving a synergistic effect of heat dissipation and dust prevention. This effectively prevents dust from entering the enclosure and extends the service life of the equipment. Forced air cooling improves heat dissipation efficiency and ensures stable operation of the distribution box in high-temperature environments.

[0014] Preferably, the top of the rainproof roof is a conical structure, and the two sides are designed to slope downwards, and the rainproof roof covers the outside of the heat dissipation mechanism.

[0015] The above technical solution utilizes the principle of gravity guidance to allow rainwater to slide down the slope quickly, preventing water accumulation. Its external shielding design can block vertical and lateral rainwater, preventing direct intrusion into the heat dissipation mechanism, improving the waterproof performance of the distribution box, and protecting the cooling fan and dust filter from rainwater erosion. It also ensures that the heat dissipation channel can still ventilate normally in rainy weather, taking into account both rain protection and heat dissipation needs.

[0016] Preferably, the heat dissipation holes are arranged longitudinally along both sides of the housing, and the inner bottom of the baffle is connected to the heat dissipation holes, and the outer surface of the baffle has an arc-shaped structure.

[0017] Using the above technical solution, the longitudinally arranged heat dissipation holes form a natural convection channel by utilizing the rising characteristics of hot air. The arc-shaped baffle guides the airflow along its curved surface through fluid dynamics design, causing rainwater to slide off the arc surface of the baffle due to centrifugal force, avoiding direct splashing into the heat dissipation holes. While ensuring efficient heat dissipation, it also achieves rain and dust prevention through directional airflow. The arc structure reduces wind resistance, lowers the risk of rainwater backflow, and extends the service life of the equipment.

[0018] Preferably, the mounting hole has an elongated waist-shaped structure, the cable tray has a concave structure, the wire hole has a horizontal design, and the outer surface of the clamp has a longitudinal groove design.

[0019] By adopting the above technical solution, the elongated mounting hole can be adapted to electrical components of different sizes through adjustable installation position, and the concave cable tray uses spatial misalignment to reduce the bending radius of the cable; the horizontal conductor hole and the vertical groove clamp form a cross-shaped fixation, which enhances the tensile strength of the cable through multi-directional constraint, improves the flexibility and compatibility of wiring, reduces installation errors, optimizes cable routing management, prevents loosening and falling off, and ensures the long-term stability of the distribution box.

[0020] Preferably, the outer surface of the winding post is provided with a spiral winding groove, the outer end of the winding post is fixed with a limiting plate, and the winding post and the mounting hole are designed to correspond one-to-one.

[0021] Using the above technical solution, the spiral winding groove guides the cable to spirally wind through a continuous curved surface, and uses friction and geometric constraints to fix the position of the cable; the limiting plate prevents the cable from slipping axially through physical blocking, and the one-to-one correspondence design with the mounting holes ensures that each electrical circuit is wired independently, realizing the classification and storage of cables and the adaptive adjustment of length, avoiding messy tangling; improving maintenance efficiency and reducing the risk of short circuits, and ensuring the utilization rate of the internal space of the distribution box and electromagnetic compatibility.

[0022] Preferably, the outer surface of the enclosure is rotatably connected to a door via a hinge, and an ammeter and a voltmeter are installed on the outer surface of the door.

[0023] Using the above technical solution, the cabinet door forms an openable structure with the cabinet body through hinges, and realizes rapid opening and closing by using the principle of mechanical rotation; the ammeter and voltmeter are connected in parallel / series with the internal circuit through wires, and monitor electrical parameters in real time based on the principle of electromagnetic induction. The cabinet door design facilitates daily maintenance and component operation, while protecting the internal equipment; the dual meters intuitively display the operating data, assist in quickly judging the circuit status, and improve the efficiency of fault diagnosis and electrical safety.

[0024] Compared with the prior art, the beneficial effects of this utility model are: the convenient wiring distribution box equipment,

[0025] 1. The horizontal wire hole and the vertical groove clamp are fixed by a cross-shaped method, combined with the elastic clamping force of the spring, to achieve multi-directional stable constraint of the cable and prevent the cable from loosening or shifting; the winding post of the spiral winding groove guides the cable to wind in a standard spiral through a continuous curved surface, and the outer end limiting plate can prevent the cable from slipping axially, ensuring that each circuit is independently stored and does not interfere with each other. This not only reduces the risk of electromagnetic interference, but also makes the wiring more neat and orderly, which is convenient for later maintenance, fault diagnosis and cable capacity expansion and modification. It greatly improves the maintainability and operational reliability of the equipment, improves maintenance efficiency, shortens power outage time, and provides convenience for production and life.

[0026] 2. The elongated mounting holes at both ends of the mounting bracket provide longitudinal adjustment space for electrical components, which can flexibly adapt to the installation needs of components of different sizes and specifications, avoiding installation difficulties or space waste caused by size mismatch. The concave structure of the cable tray forms a layered layout with the mounting bracket, which reduces the bending radius of the cables by using spatial misalignment, making the internal layout of the box more compact and reasonable, and effectively improving the equipment installation density and wiring capacity in a limited space.

[0027] 3. The inner and outer dust filters of the heat dissipation mechanism form a double-layer filtration system, which effectively intercepts dust from entering the cabinet and prevents dust accumulation from affecting the performance of electrical components and heat dissipation efficiency. The cooling fan drives the airflow to form a cooling channel, which, together with the longitudinally arranged heat dissipation holes on both sides of the cabinet and the directional heat dissipation path constructed by the guide plate, accelerates the discharge of hot air, ensures that the temperature inside the cabinet is stable within a reasonable range, and significantly improves the equipment's ability to operate continuously in high-temperature environments.

[0028] 4. The conical top surface and downward-sloping side panels of the rainproof roof form an efficient rainwater diversion system, completely covering the area above the heat dissipation mechanism. Gravity allows rainwater to slide quickly down the slope, preventing water accumulation and leakage. The arc-shaped baffle guides airflow and deflects rainwater through fluid dynamics design. Its inner bottom is connected to the heat dissipation holes to ensure heat dissipation, while the arc-shaped structure on the outer surface causes rainwater to deviate from the inlet due to centrifugal force. Combined with the metal dustproof mesh, it provides protection, effectively resisting the intrusion of rainwater and dust, extending the service life of the equipment, and reducing maintenance costs.
