The inner side of the rubber strapping 601 is tightly fitted with the outer side of the rubber protective jacket 5. The outer side of the arc-shaped block 604 is tightly slidably fitted with the inner wall of the splicing arc-shaped slot 603.

[0037] A suspension rubber ball 606 is fixedly connected to the top of the end of the connecting cable 605. Limiting corner pins 607 are threadedly installed at both corners of the top of the connecting rectangular block 602. The suspension rubber ball 606 has an internal cavity. The ends of the limiting corner pins 607 are tightly fitted to the top surface of the connecting rectangular block 602.

[0040] The rubber protective jacket 5 is tightly wrapped with a silicone connecting sleeve 701 at the outer position of the corresponding limiting rubber sleeve 3. The outer side of the silicone connecting sleeve 701 is tightly wrapped with a waterproof expansion silicone layer 702.

[0041] The outer side of the waterproof expansion silicone layer 702 is provided with arc-shaped mounting grooves 703 evenly spaced along the circumferential direction. The arc-shaped mounting grooves 703 are filled with expansion strips 704. The outer side of the waterproof expansion silicone layer 702 is tightly fitted with the inner side of the rubber protective jacket 5, and the outer side of the expansion strips 704 is tightly fitted with the inner wall of the arc-shaped mounting grooves 703.

The inner cavity of the limiting rubber sleeve 3 is filled with the internal filling strip 4. The outer side of the cable is protected by the rubber protective outer sleeve 5. The connecting rectangular block 602 and its components are installed onto the outer side of the rubber protective outer sleeve 5 using the rubber bundling strap 601. Finally, the splicing arc... The shaped slot 603 engages the arc-shaped locking block 604 with the inside of the connecting rectangular block 602, and the limiting corner pin 607 limits the arc-shaped locking block 604 to prevent it from slipping. Then, the connecting cable 605 installs the suspending rubber ball 606 on the top of the arc-shaped locking block 604. The suspending rubber ball 606 marks the direction and arrangement of the low-voltage cable, ensuring that the position of the low-voltage cable can be quickly determined during underwater use. This effectively prevents the cable from being accidentally scratched or damaged by personnel working on the water, thereby effectively improving the safety of the cable.

[0044] When waterproof protection is required on the outside of the cable, the waterproof expansion silicone layer 702 and its components are installed on the outside of the limiting rubber sleeve 3 through the silicone connecting sleeve 701. Then, the expansion strip 704 is installed inside the rubber protective jacket 5 through the arc-shaped mounting groove 703, and the expansion strips 704 are connected to each other through the connecting strips 705. When the cable is damaged by penetration, the sealant leaking from the inside of the expansion strip 704 seals the cable wound, effectively preventing water from the outside of the cable from entering the inside of the cable, thereby effectively improving the overall waterproof performance of the cable.
