[0020] Reference Figure 1 to Figure 7 An outdoor power distribution cabinet is proposed for installing a plurality of electrical control components 1, including: a cabinet body 2 having an installation space 3 and an installation hole 4 connected to the installation space 3, the installation space 3 being used to place a plurality of electrical control components 1; a cable 5 having a plurality of holes 4 connected to the installation space 3 as a further technical solution to supply power to the electrical control components 1; an insulating protection component 6 is arranged in the installation space 3, a plurality of cables 5 pass through the insulating protection component 6 to be connected to the electrical control components 1, the insulating protection component 6 is used to prevent the cables 5 from contacting the cabinet body 2 when disconnected; the insulating protection component 6 includes: a fixing sleeve 7 made of insulating material, arranged in the installation space 3; a fastening sleeve 8 also made of insulating material, slidably arranged in the fixing sleeve 7, the fastening sleeve 8 is used to fix the cables 5 to prevent the cables 5 from detaching, and to feed the cables 5 into the fixing sleeve 7.

[0021] In this embodiment, the cabinet 2 provides a special installation space 3, which can effectively protect the electrical control component 1 from the influence of the external environment and ensure its normal operation. The installation hole 4 facilitates the introduction of the cable 5 into the installation space 3 to supply power to the electrical control component 1. The reasonable layout of the various components in the cabinet 2 facilitates the overall maintenance of the distribution box. If an unexpected situation occurs, such as long-term aging of the distribution box components, and strong winds blow down the accessory cabinet, the cable 5 will enter the insulating protective member 6 at this time. The insulating protective member 6 can effectively prevent the cable 5 from contacting the cabinet 2, thereby avoiding the occurrence of leakage accidents and greatly improving the safety of the use of the distribution cabinet. The insulating protective member 6 can fix and organize the cable 5, prevent the cable 5 from being tangled in the cabinet 2, and facilitate the inspection and maintenance of the line; the fixing sleeve 7 and the fastening sleeve 8 are both made of insulating materials and can provide insulation protection. The cable 5 is fixed inside the fastening sleeve 8 when in use. If an unexpected situation occurs and causes the cable 5 to be disconnected from the electrical control component 1, the fixing sleeve 7 still tightly fixes the cable. As the cable is detached, the fastening sleeve 8 will slide in the fixing sleeve 7, and will eventually be restricted in its sliding position by the fixing sleeve 7. At this time, the disconnected wire ends will enter the fixing sleeve 7 to prevent the wire ends from contacting the side wall of the cabinet and causing electric shock accidents. The safety of the power distribution cabinet is improved. The fastening sleeve 8 is slidably arranged in the fixing sleeve 7, and the position of the fastening sleeve 8 can be easily adjusted to better adapt to cables 5 of different numbers and diameters, thereby improving the versatility of the insulating protective part 6. The fastening sleeve 8 can effectively fix the cable 5, prevent the cable 5 from detaching when it is pulled or vibrated by external force, and ensure the stability of the connection of the cable 5. When the cable 5 needs to be installed or replaced, the sliding fastening sleeve 8 can open a certain space to facilitate the insertion and fixation of the cable 5, thereby improving the convenience of operation.

[0022] As a further technical solution, the outer surface of the fastening sleeve 8 is a slope, and after the fastening sleeve 8 slides, one end enters or leaves the fixed sleeve 7, and one end of the fastening sleeve 8 has a plurality of notches 9 and external threads, and also includes: a fastening bolt 10 is detachably arranged on the fastening sleeve 8, the fastening bolt 10 cooperates with the external thread, and the fastening bolt 10 is used to fix the fastening sleeve 8 on the cable 5.

[0023] In this embodiment, the outer surface of the fastening sleeve 8 is an inclined surface. This design allows the clamping force on the cable 5 to be gradually increased during the sliding process, achieving a better fixing effect, and also adapting to cables 5 of different diameters. The plurality of notches 9 at one end of the fastening sleeve 8 allow it to shrink and deform more easily when subjected to the pressure of the fastening bolt 10, thereby wrapping the cable 5 more tightly and enhancing the fixing effect. The cooperation between the external thread and the fastening bolt 10 can conveniently adjust the position of the fastening bolt 10, thereby accurately controlling the degree of clamping of the fastening sleeve 8 on the cable 5, and meeting the fixing requirements of different cables 5.

[0024] As a further technical solution, there are a plurality of matching blocks 11 disposed in the fastening sleeve 8 , and a clamping space 13 is formed between the matching blocks 11 , and the clamping space 13 is used to clamp the cable 5 .

[0025] In this embodiment, the provision of the matching block 11 enables the clamping of the cable 5 by the fastening sleeve 8 to have better adaptability, and can adapt to cables 5 of different shapes and surface characteristics, thereby improving versatility. Multiple matching blocks 11 work together to disperse the clamping force while clamping the cable 5, thereby avoiding damage to the cable 5 due to excessive local pressure, and helping to extend the service life of the cable 5. The formation of the clamping space 13 ensures that the position of the cable 5 in the fastening sleeve 8 is fixed, and will not loosen due to vibration of the distribution cabinet or external force interference, thereby enhancing the stability of the system. The matching block 11 can be made of materials with different hardness and friction coefficients, and can be selected according to the characteristics of the cable 5 and the use environment to optimize the clamping effect and protective performance.

[0026] As a further technical solution, the fastening sleeve 8 has a groove 14 at one end located in the fixing sleeve 7, and also includes: a plug 15 detachably arranged at the other end of the fastening sleeve 8, the plug 15 is sleeved on the cable 5, and the plug 15 has a plurality of grooves 16; a clamping block 17 is arranged on the plug 15, and the clamping block 17 has a mating surface 18. After the plug 15 is installed, the clamping block 17 abuts against the groove 14, and the clamping block 17 is used to enable the plug 15 to clamp the cable 5.

[0027] In this embodiment, the groove 14 at one end of the fastening sleeve 8 provides a good contact structure for cooperation with the clamping block 17, so that the clamping block 17 can more effectively apply the clamping force, and enhance the fixing effect of the plug 15 on the cable 5. The detachable plug 15 is easy to install and disassemble, and is convenient for maintenance and replacement of the cable 5, thereby improving work efficiency. The plurality of notches 16 on the plug 15 can increase its elastic deformation capacity, so that it can better adapt to cables 5 of different diameters and provide a tighter package.

[0028] As a further technical solution, it also includes: a clamping block 19 is arranged on the plugging 15 , and the clamping block 19 is used to limit the plugging 15 from entering the fastening sleeve 8 .

[0029] In this embodiment, the setting of the block 19 can effectively limit the plug 15 from excessively entering the fastening sleeve 8, ensuring that the plug 15 functions in the correct position, and avoiding the clamping and sealing effects affected by the improper position of the plug 15. It prevents the plug 15 from completely entering the fastening sleeve 8 and being difficult to remove, and facilitates the subsequent maintenance, replacement or adjustment of the plug 15. The block 19 can clearly locate and indicate the installation position of the plug 15, so that the operator can quickly and accurately install the plug 15 in place. Limiting the entry depth of the plug 15 helps to maintain a stable abutment between the clamp block 17 and the groove 14, thereby ensuring the continuity and stability of the clamping force.

[0030] As a further technical solution, it also includes: there are a plurality of extension sleeves 20 made of insulating material, and the plurality of extension sleeves 20 are slidably arranged in the fastening sleeve 8 , and the fastening sleeve 8 is slidably arranged in the fixing sleeve 7 through the extension sleeve 20 .

[0031] In this embodiment, the extension sleeve 20 is made of insulating material, which further enhances the insulation protection effect, reduces the risk of leakage, and improves the safety of the power distribution cabinet. The provision of multiple extension sleeves 20 increases the sliding stability and guidance of the fastening sleeve 8, making its movement between the fixing sleeve 7 and the cable 5 more stable and accurate. The extension sleeve 20 can adjust the length according to actual needs, so as to adapt to cables 5 of different lengths and internal spaces of power distribution cabinets of different sizes, thereby improving versatility.

[0032] As a further technical solution, it also includes: the insulating shell 21 is detachably arranged on the cabinet 2 , and the insulating shell 21 has a plurality of mounting grooves 22 , and the mounting grooves 22 are used to fix the fixing sleeve 7 .

[0033] In this embodiment, the detachable setting of the insulating shell 21 facilitates the installation, maintenance and replacement of the insulating protection member 6, and improves the convenience of operation. The insulating shell 21 itself can provide additional insulation protection, enhance the insulation performance of the entire distribution cabinet, and further reduce the possibility of leakage. The design of the mounting groove 22 enables the fixing sleeve 7 to be stably fixed on the insulating shell 21, preventing the fixing sleeve 7 from being displaced or loosened during use, thereby ensuring the reliability of insulation protection. When insulation protection is required for cables 5 of different specifications or quantities, the insulating shell 21 with the corresponding mounting groove 22 layout can be replaced, thereby improving the adaptability of the distribution cabinet.

[0034] As a further technical solution, the insulating shell 21 is divided into an upper shell 23 and a lower shell 24 , and the upper shell 23 and the lower shell 24 jointly fix the fixing sleeve 7 .

[0035] In this embodiment, the insulating shell 21 is divided into an upper shell 23 and a lower shell 24, which facilitates the installation and removal of the fixing sleeve 7. During installation, the fixing sleeve 7 can be placed on the lower shell 24 first, and then the upper shell 23 is covered to fix it, which makes the operation more convenient. When the fixing sleeve 7 or the internal cable 5 needs to be inspected and maintained, the upper shell 23 and the lower shell 24 can be disassembled without the need to disassemble the entire insulating shell 21 as a whole, thereby improving the maintenance efficiency. This split design makes the insulating shell 21 more convenient during manufacturing and transportation, and reduces the cost and difficulty. The upper shell 23 and the lower shell 24 jointly fix the fixing sleeve 7, which can provide a more uniform clamping force, ensure the stable installation of the fixing sleeve 7, and improve the reliability of insulation protection.
