Description
Technical Field
[0001] This utility model relates to the field of distribution box technology, specifically to a cable management system for distribution boxes. Background Technology
[0002] Cable management systems are devices used in power systems, particularly inside distribution boxes or electrical cabinets, to help manage and organize wires and cables. With the increasing electricity demands of modern industry and buildings, the complexity of power distribution systems is also constantly growing. To ensure the safe and reliable operation of power systems, the proper management and maintenance of cables within distribution boxes has become particularly important.
[0003] However, traditional cable management systems typically use fixed sizes and layouts, which limits their flexibility. Adding new functional modules, such as additional terminals, sensors, or heat dissipation units, usually cannot be achieved through simple plugging and unplugging or reconfiguration. Typically, such upgrades require rewiring or custom adapters, which not only increases operating costs but also reduces management efficiency. Therefore, we propose a cable management system for distribution boxes to address these issues. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, this utility model provides a cable management strip for distribution boxes, which improves the flexibility of using the cable management strip for distribution boxes.
[0005] The technical implementation scheme of this utility model is as follows: a cable management strip for a distribution box, including a cable strip frame, the cable strip frame being the assembly carrier of the cable strip, a wedge-shaped docking groove for splicing extension cable strips on one side of the cable strip frame, a wedge-shaped protrusion adapted to the docking groove on one side of the extension cable strip opposite to the cable strip frame, and a locking groove on one side of the wedge-shaped protrusion of the extension cable strip; it also includes a wedge block, a lever, a telescopic rod, a spring, a support plate, a mounting plate, and two mounting bolts; a sliding groove is provided at the docking groove on the side of the cable strip frame opposite to the extension cable strip, and a support plate is fixedly connected in the sliding groove of the cable strip frame. A wedge block is slidably connected to the support plate via a telescopic rod. A spring is provided between the wedge block and the support plate. The wedge block is used to lock the spliced extension cable strip. A lever is fixed to the top of the wedge block, which facilitates the operation of the wedge block to lock the extension cable strip. A mounting plate is mounted on one side of the cable strip frame via mounting bolts. The mounting plate is equipped with a heat sink for heat dissipation of the cable strip frame. The modular splicing of the extension cable strip and the cable strip frame allows the entire cable strip to be expanded and used as needed. The wedge block facilitates easy locking, improving the range of use and flexibility of this cable strip.
[0006] Furthermore, both the cable tray frame and the extension cable tray are equipped with cable trays on their top surfaces. The top surface of the cable trays has multiple fixing heads for organizing and securing cables. The cable trays are detachably mounted to the cable tray frame and the extension cable trays via mounting bolts. By tightening or loosening the mounting bolts, the cable trays on the cable tray frame and the extension cable trays can be easily replaced and maintained, thus improving the service life of the cable trays.
[0007] Furthermore, the heat dissipation component includes a fan and an exhaust filter. An air inlet is provided on one side of the mounting plate, and a fan is installed at the air inlet of the mounting plate. The fan is used to blow air into the cable tray frame for heat dissipation. An air outlet is provided on the other side of the mounting plate, and an exhaust filter is installed at the air outlet of the mounting plate. With the fan and the exhaust filter working together, the cable tray frame has a good heat dissipation effect, which improves the effective heat dissipation of the cables combed and fixed on the cable tray.
[0008] Furthermore, a temperature sensor is mounted on the mounting plate of the cable tray via a slot. The temperature sensor is inserted inside the cable tray, and its temperature-sensing contact is in contact with the cable tray. The temperature sensor is electrically connected to the fan via a built-in controller. The temperature sensor is used to monitor the temperature on the cable tray in real time and to control the cooling power of the fan via the controller.
[0009] Furthermore, it also includes an identification plate. A groove is provided on the outer wall of the mounting plate, and an identification plate is placed in the groove of the mounting plate. The identification plate is used to identify the type of cable currently being combed on the cable tray, so as to facilitate user identification and maintenance of the cable.
[0010] Furthermore, the sign is made of magnetic metal, and the mounting plate has a groove with a magnet for attracting the sign. The magnet allows the sign with the cable information to be easily mounted onto the mounting plate, while also facilitating modification and maintenance.
[0011] This utility model has the following advantages:
[0012] 1. This utility model, through the design of wedge-shaped docking groove and wedge-shaped protrusion, enables the wire strip frame and the expansion wire strip to be easily modularly spliced. This design allows for flexible expansion of the wire strip's function according to actual needs, effectively improving the flexibility and scope of wire strip use.
[0013] 2. This utility model can quickly and securely lock or unlock the extension cable by using a buckle locking system composed of wedge blocks, springs and levers, simplifying the installation and disassembly process.
[0014] 3. This utility model is equipped with a fan and an exhaust filter, which can effectively blow air to dissipate heat inside the cable tray frame. With the help of a temperature sensor, the temperature is monitored in real time and the fan power is automatically adjusted to ensure that the cable operates at the optimal operating temperature, thereby improving the stability and safety of the system.

Detailed Implementation
[0020] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0021] A type of cable management system for distribution boxes, such as Figures 1-4As shown, the device includes a wire frame 1, which serves as the assembly carrier for the wire strip. One side of the wire frame 1 has a wedge-shaped mating groove 21 for connecting an extension wire strip 2. The side of the extension wire strip 2 opposite to the wire frame 1 has a wedge-shaped protrusion adapted to the mating groove 21. A locking groove is provided on one side of the wedge-shaped protrusion of the extension wire strip 2. The device also includes a wedge block 3, a lever 31, a telescopic rod 4, a spring 5, a support plate 6, a mounting plate 7, and mounting bolts 71. A sliding groove is provided at the mating groove 21 on the side of the wire frame 1 where it connects to the extension wire strip. The support plate 6 is fixedly connected within the sliding groove of the wire frame 1, and the support plate 6 is slidably connected via the telescopic rod 4. A wedge block 3 is connected, and a spring 5 is provided between the wedge block 3 and the support plate 6. The wedge block 3 is used to lock the spliced extension cable 2. A lever 31 is fixed on the top of the wedge block 3, which facilitates the operation of the wedge block 3 to lock the extension cable 2. A mounting plate 7 is assembled on one side of the cable frame 1 by mounting bolt 2 71. The mounting plate 7 is provided with a heat dissipation component for heat dissipation of the cable frame 1. The extension cable 2 and the cable frame 1 are modularly spliced, so that the entire cable can be expanded and used as needed. With the wedge block 3, it is easy to lock, which improves the application range and flexibility of this cable.
[0022] like Figure 1 and Figure 2 As shown, both the cable tray frame 1 and the extension cable tray 2 are equipped with cable trays 101 on their tops. The top surface of the cable tray 101 is provided with multiple fixing heads 102 for organizing and fixing cables. The cable tray 101 is detachably installed on the cable tray frame 1 and the extension cable tray 2 by mounting bolts 103. By tightening and loosening the mounting bolts 103, the cable trays 101 on the cable tray frame 1 and the extension cable tray 2 can be easily replaced and maintained, thereby improving the service life of the cable trays.
[0023] like Figure 3 As shown, the heat dissipation component includes a fan 9 and an exhaust filter 10. An air inlet is provided on one side of the mounting plate 7, and a fan 9 is installed at the air inlet of the mounting plate 7. The fan 9 is used to blow air into the cable tray frame 1 for heat dissipation. An air outlet is provided on the other side of the mounting plate 7, and an exhaust filter 10 is installed at the air outlet of the mounting plate 7. With the fan 9 and the exhaust filter 10 working together, the cable tray frame 1 has a good heat dissipation effect, which can effectively dissipate heat from the cables that are combed and fixed on the cable tray.
[0024] like Figure 4 As shown, a temperature sensor 8 is installed on the mounting plate 7 of the cable tray frame 1 through a slot. The temperature sensor 8 is inserted inside the cable tray frame 1. The temperature sensing contact of the temperature sensor 8 is in contact with the cable tray 101. The temperature sensor 8 is electrically connected to the fan 9 through a built-in controller. The temperature sensor 8 is used to monitor the temperature on the cable tray in real time and control the heat dissipation power of the fan 9 through the controller.
[0025] like Figure 3 and Figure 4As shown, it also includes a label 11. A groove is provided on the outer wall of the mounting plate 7, and the label 11 is placed in the groove of the mounting plate 7. The label 11 is used to identify the type of cable currently combed on the cable tray frame 1, so as to facilitate user identification and maintenance of the cable. The label 11 is made of magnetic metal material. A magnet 12 is provided in the groove of the mounting plate 7 for adsorbing the label 11. The label 11 with the cable information marked can be easily assembled onto the mounting plate 7 by the magnet 12, and it is also convenient to make changes and maintenance.
[0026] When using this cable strip to manage cables in a distribution box, its modular design allows for flexible expansion. To increase cable capacity, the wedge-shaped protrusion of the expansion cable strip 2 is aligned with the wedge-shaped mating groove 21 of the cable strip frame 1. The expansion cable strip 2 then pushes the wedge-shaped block 3 in the groove backward, compressing the spring 5. Once the protrusion is fully embedded in the mating groove 21, the spring 5 rebounds, driving the wedge-shaped block 3 into the locking groove of the expansion cable strip 2, thus completing the mechanical locking of the cable strip frame 1 and the expansion cable strip 2. Operators can manually adjust the position of the wedge-shaped block 3 using the lever 31 to quickly disassemble or reassemble the cable strip, meeting the wiring needs of different scenarios. Cables are then sorted and managed using the fixing head 102 on the cable strip board 101. Subsequently, the temperature sensor 8 monitors the temperature of the ribbon cable board 101 in real time. When the temperature rise exceeds the set threshold, the sensor starts the fan 9 through the controller, blowing external cold air into the ribbon cable frame 1 through the air inlet. After accelerating the airflow circulation, the air is discharged through the air outlet filter 10, forming an active heat dissipation air duct. At the same time, the air outlet filter 10 can prevent dust from entering. The sensor will dynamically adjust the speed of the fan 9 according to the temperature to achieve intelligent temperature control. During maintenance, the mounting bolt 103 can be loosened to replace the ribbon cable board 101 of different specifications to adapt to changes in cable diameter. At the same time, the cable type information is marked by the magnetic label 11, which is attached to the groove of the mounting plate 7 by the magnet 12 for easy identification and later maintenance.
[0027] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
