Description

Technical Field

[0001] This utility model relates to the field of wire and cable protection technology, specifically a waterproof and tear-resistant wire and cable. Background Technology

[0002] With the development of the power and energy industries, various wires and cables are increasingly used in all aspects of production and daily life. The government is gradually increasing investment in the power grid and improving its construction. Waterproof and tear-resistant wires and cables are specially designed to improve their durability and safety in outdoor or specific environments. These cables typically employ a multi-layered structure to enhance their waterproof performance and resistance to animal bites. The different laying sites for wires and cables lead to varying protective objectives. In areas with good ecological environments, the damage caused by bites from animals of all sizes and the impact of rainfall must be considered. Prolonged use can cause damage to the protective sheath at bite points, reducing protection and leading to leakage or poor transmission. Therefore, we have designed a waterproof and tear-resistant wire and cable.

[0003] Existing waterproof and tear-resistant wires and cables have poor stability in the connection between cables and are easily broken at the connection point due to external forces, affecting the operation of the cable. In addition, the existing waterproof and tear-resistant wires and cables have poor waterproof and tear-resistant effects, which affects the service life of the cable. The present invention provides a waterproof and tear-resistant wire and cable that solves the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Please see Figures 1 to 4This utility model provides a technical solution: a waterproof and tear-resistant wire and cable, including a first cable 1 and a second cable 2. A first protective cover 3 is installed on the outer surface of the first cable 1. The maximum diameter of the first protective cover 3 is larger than the maximum diameter of the second protective cover 9. The end of the second protective cover 9 is located inside the first protective cover 3. A U-shaped plate 4 is installed on the outer surface of the first protective cover 3. A compression spring 5 is installed on the inner bottom wall of the U-shaped plate 4. A pressure plate 6 is installed at one end of the compression spring 5. A locking block 7 is installed at the bottom of the pressure plate 6. An internal threaded ring 8 is installed on the inner surface of the first protective cover 3. The internal threaded ring 8 is threadedly connected to an external threaded ring 10. The pressure plate 6 is rotatably connected to the U-shaped plate 4 via a shaft, and the end of the pressure plate 6 is located inside the U-shaped plate 4. The outer surface of cable 2 is fitted with a second protective cover 9, which is fitted over the annular stop block 13. There are two mating blocks 11, and the maximum distance between the two mating blocks 11 is greater than the maximum diameter of the external threaded ring 10. The outer surface of the second protective cover 9 is respectively equipped with an external threaded ring 10 and mating blocks 11. A slot is opened on one side of the mating block 11, and the end of the locking block 7 away from the pressure plate 6 is inserted into the slot. A sealing ring 12 is installed on the inner wall of the second protective cover 9. The outer surface of the second cable 2 is equipped with an annular stop block 13. The ends of the first cable 1 and the second cable 2 are both provided with connectors 14. The connectors 14 are located in the cavity formed between the first protective cover 3 and the second protective cover 9. The sealing ring 12 abuts against the annular stop block 13.

[0026] In use, when connecting cables, move the first cable 1 and the second cable 2 to connect the connectors 14 on the first cable 1 and the second cable 2. Then rotate the pressure plate 6 to compress the contraction spring 5, causing the locking block 7 to rotate in an arc trajectory. Then rotate the external threaded ring 10 to connect the internal threaded ring 8 with the external threaded ring 10. This causes the second protective cover 9 to slowly move towards the inside of the first protective cover 3. The sealing ring 12 abuts against the annular stop block 13 to improve the sealing of the connection. When the internal threaded ring 8 and the external threaded ring 10 are tightened, the locking block 7 is aligned with the slot on the mating block 11. Release the pressure plate 6, and through the elastic contraction force of the contraction spring 5, the end of the locking block 7 is inserted into the slot, which helps to limit the position of the mating block 11 and the external threaded ring block 10, improves the stability of the connection between the connectors 14, and improves practicality.

[0027] Example 2

[0028] Please see Figures 1 to 5The present invention provides a technical solution: a waterproof and tear-resistant wire and cable, wherein the first cable 1 and the second cable 2 are both composed of an ethylhexanoate coating 15, a protective layer 16, a connecting layer 17, a waterproof layer 18, an insulation layer 19 and a wire core 20. The ethylhexanoate coating 15 is disposed outside the protective layer 16, the protective layer 16 is disposed outside the connecting layer 17, the connecting layer 17 is disposed outside the waterproof layer 18, the waterproof layer 18 is disposed outside the insulation layer 19, and the insulation layer 19 is disposed outside the wire core 20.

[0029] When used, ethylhexanoate can be used as a repellent. The ethylhexanoate coating 15 repels rodents and prevents them from biting the cable. The protective layer 16 provides external protection. The connecting layer 17 creates a certain gap inside the cable, improving its resistance to compression. The waterproof layer 18 enhances the waterproof effect, extends the cable's service life, and improves its practicality.
