The sliding groove 202 provides a sliding track for the slider 22, making the sliding block 203 slide more stably and orderly.

[0043] Reference Figure 2 , Figure 3 and Figure 4 A cover plate 14 is fixedly connected to the top perimeter of the top cover 4. The cover plate 14 can further reinforce and protect the top perimeter of the top cover 4, enhancing the overall structural strength. The inner wall of the cover plate 14 is slidably connected to the top perimeter of the outer shell 1. The cover plate 14 can be adjusted in position and protect the top structure through its sliding connection with the outer shell 1. Buckles 15 are fixedly connected to the front and rear sides of the cover plate 14. The buckles 15 are used to cooperate with other components to provide connection and fixation functions. Slots 16 are fixedly connected to the front and rear sides of the outer shell 1. The slots 16 provide connection positions for the buckles 15. A ring 17 is fixedly connected to the right side of the outer wall of the inlet tube 6. The ring 17 can reinforce the outer wall of the inlet tube 6. For protection, a sealing groove 18 is provided on the right side of the ring 17. The sealing groove 18 provides an installation position for the sealing ring 19, enhancing the sealing of the connection. The sealing ring 19 is fixedly connected to the left outer wall of the connecting ring 10. The sealing ring 19 can be embedded in the sealing groove 18 to achieve sealing when the inlet tube 6 is connected to the connecting ring 10, preventing impurities from entering. The outer walls of multiple fixing bolts 206 are slidably connected with gaskets 20. The gaskets 20 provide support and buffer for the fixing bolts 206, reducing friction. The bottom of multiple gaskets 20 is in contact with the top of the corresponding connecting plate 204. The contact between the gaskets 20 and the connecting plate 204 increases the contact area and prevents damage to the surface of the connecting plate 204.

[0044] Specifically, after the top cover 4 is closed, it provides additional protection for the top of the control box, enhancing the protective performance of the top of the housing 1. It is used to cooperate with the slots 16 on the front and rear sides of the housing 1. Through the connection of the buckle 15 and the slot 16, the cover plate 14 can be fixed on the housing 1, providing a sealed space for the sealing ring 19. When the connecting ring 10 is connected to the inlet tube 6, the sealing ring 19 can be embedded in the sealing groove 18, thereby forming a seal at the connection between the inlet tube 6 and the connecting ring 10. The main function of the gasket 20 is to increase the contact area between the fixing bolt 206 and the connecting plate 204, disperse the pressure when the fixing bolt 206 is tightened, prevent the fixing bolt 206 from damaging the surface of the connecting plate 204, and improve the stability of the connection.

[0045] Working Principle: When using a power distribution terminal control box, the limiting groove 3 on the top of the outer casing 1 provides a sliding track for the top cover 4. The top cover 4 slides within the limiting groove 3, protecting the internal components. The cable inlet grooves 5 at both ends of the right side of the outer casing 1 provide an entrance for external cables to enter the control box. The internal cable inlet cylinder 6 guides the cable in. When the cable passes through the cable inlet cylinder 6, the fastening nut 8 can be rotated to tighten it on the fastening ring 7. The fastening nut 8 compresses the cable, firmly fixing it inside the cable inlet cylinder 6, preventing the cable from loosening or shifting during operation, and ensuring the stability and safety of the cable connection. Simultaneously, during installation, the locking block 9 is aligned with the connecting groove 11 and slid in to ensure the cable is properly secured. The connection between the coil 6 and the connecting ring 10 is secure, and when it is necessary to replace the connecting ring 10 or the external equipment connected to it, it can be easily disassembled by simply sliding the locking block 9 out of the connecting groove 11, which improves the convenience of maintenance and replacement. When it is necessary to install the power distribution terminal control box, its position can be adjusted by sliding the connecting plate 204 to adapt to different installation environments and requirements. The top two ends of the connecting plate 204 are provided with reserved holes 205 for installing fixing bolts 206, and the fixing bolts 206 can rotate in the reserved holes 205. By screwing the fixing bolts 206 into the corresponding installation position, the power distribution terminal control box can be firmly fixed.
