Detailed Implementation
[0023] The embodiments of this utility model will be further described below with reference to the accompanying drawings:
[0024] Depend on Figure 1 As shown, a waterproof data cable includes a sheath 1, and further includes:
[0025] The conductor core 2 is used for signal transmission; the conductor core 2 includes a conductor 21.
[0026] The first water-blocking strip 22 covers the conductor 21 to prevent water from seeping into the conductor 21.
[0027] Insulating layer 23 covers the outside of the first water-blocking strip 22;
[0028] Shielding layer 3 is disposed outside insulating layer 23 and is used for signal shielding;
[0029] The filling material 4 is placed inside the shielding layer 3 and is bonded to the insulating layer 23;
[0030] The second water-blocking strip 5 covers the outside of the shielding layer 3 to prevent water from seeping into the conductor 21; the sheath 1 covers the outside of the second water-blocking strip 5. The beneficial effects of this utility model are that the first and second water-blocking strips are set to prevent water from penetrating longitudinally, and have good water-blocking and shielding effects, making the transmitted signal more stable; it improves the performance of the product in water-related environments and effectively extends its service life in water-related environments.
[0031] The conductor core 2 comprises multiple conductors 21, each conductor 21 having a first water-blocking tape 22 and an insulation layer 23. The different conductors 21 are concentric and arranged in a ring. Specifically, the conductors 21 are formed by stranding and the outer surface of the conductors 21 is impregnated with waterproof grease (not shown in the figure). The stranding of the conductors reduces the gaps between them, and after stranding, the conductors are vacuum impregnated with waterproof grease to fill the microscopic gaps. Specifically, the outer layer of the conductor is covered with a first water-blocking tape (super absorbent fiber) to prevent water from penetrating longitudinally.
[0032] The filling material 4 includes water-blocking yarn 41, which is located at the center of different conductors 21 to improve the roundness of the wire. Specifically, the water-blocking yarn 41 is integrally formed from nylon yarn or polyester fiber. Using water-blocking yarn to fill the cable can ensure the roundness of the semi-finished wire when it is cabled, and at the same time, it can prevent water from seeping into the gaps in the cable.
[0033] The filling material 4 includes water-blocking powder 42, which is disposed between different conductors 21. Specifically, the water-blocking powder 42 is integrally molded from water-absorbing resin. The water-blocking powder (water-absorbing resin) filling the gaps between the stranded conductors expands and blocks the gaps when it comes into contact with water.
[0034] Both the first water-blocking strip 22 and the second water-blocking strip 5 are integrally molded from absorbent fibers. This prevents water from penetrating longitudinally and improves the waterproof rating. It can improve the performance of the signal line in water-related environments and effectively extend its service life in water-related environments.
[0035] The shielding layer 3 is made of tin-plated copper braid, and the gaps in the braid are filled with waterproof adhesive. The gaps in the braided shielding layer are filled with waterproof adhesive to prevent water from seeping into the braided shielding layer. The outer layer of the shielding layer is covered with a second water-resistant tape, which can prevent water from seeping in and also prevent the wire sheath from peeling off.
[0036] The insulation layer 23 is integrally molded from cross-linked polyethylene, and the sheath 1 is integrally molded from thermoplastic polyurethane rubber. The insulation layer uses waterproof cross-linked polyethylene to improve the conductor's waterproof performance, while the sheath uses TPU (thermoplastic polyurethane rubber) to enhance its water resistance. This waterproof data cable has excellent water-blocking and shielding effects, making the transmitted signal more stable; it can improve the performance of the signal cable in water-related environments and effectively extend its service life in such environments.
