[0002] With the rapid development of information technology, the Internet has become one of the indispensable infrastructures of modern society. As an important physical medium for network connection, the performance of network cables directly affects the stability and efficiency of data transmission. However, when network cables are used in complex and changing environmental conditions, their waterproof effect is often unsatisfactory. Especially in humid, rainy or underwater environments, it is difficult for existing network cables to effectively prevent moisture penetration, which can cause the internal lines of the network cables to become damp, short-circuited or even damaged, seriously affecting the stability and security of network connections.

[0003] At present, there are some network cables with waterproof function on the market, which use internal waterproof structure to improve the waterproof function of the network cable, but the existing waterproof network cables have many shortcomings. For example, after the network cable has been used for a period of time, it is easy to be crushed, scratched or used for a long time, resulting in damage to the waterproof layer or looseness of the internal waterproof structure, which directly leads to a significant decrease in its waterproof effect, and thus fails to achieve the desired waterproof effect, which in turn causes internal water seepage and affects the normal use of the network cable.

[0030] Embodiment 1:

[0031] In order to solve the problem that the current network cable is prone to water ingress in a water-related environment, resulting in a decrease in insulation performance, affecting the normal use of the network cable, and causing certain safety risks to the network cable. Figure 1-3 The present embodiment provides a network cable with a waterproof structure, which specifically includes a core unit 10 and an isolation frame 20, wherein the core unit 10 is provided with a twisted pair core 11 for realizing its network signal transmission function. The isolation frame 20 is used to improve the compression resistance of the network cable and isolate the multiple core units 10 inside the network cable in different areas, thereby maintaining the tightness inside the network cable and achieving an optimized waterproof effect.

[0032] In order to improve the waterproof capability of the product and solve the problem of easy water seepage in the current network cable, this embodiment is based on the isolation area of ​​the isolation frame 20, and is provided with two waterproof mechanisms: external waterproof and internal waterproof. Figure 1-3 In terms of external waterproofing, the first waterproof layer 50, the first insulating layer 60 and the sheath 70 are arranged on the outside of the isolation frame 20 from the inside to the outside in sequence, and the first waterproof layer 50, the first insulating layer 60 and the sheath 70 are used to separate the internal and external environments of the network cable to prevent water vapor from the external environment from entering the inside of the network cable. The first waterproof layer 50 and the first insulating layer 60 can be arranged on the protective belt, the first waterproof layer 50 is made of waterproof material, such as a polyisobutylene layer, the first insulating layer 60 is correspondingly made of insulating material, such as a high-density polyethylene insulating layer, and the sheath 70 plays a role in preventing damage and protecting the internal structure.

[0033] Internally, the isolation skeleton 20 includes an axis seat 21 and a plurality of brackets 22. The plurality of brackets 22 are evenly protruded outward from the axis seat 21 at equal distances, and form a plurality of isolation areas of equal size. Specifically, two core units 10 are arranged in each isolation area. The core units 10 are used to realize the signal transmission function of the network cable. The two core units 10 are respectively arranged close to the brackets 22 on both sides of the isolation area. A filling strip 30 is arranged between the core unit 10 and the first waterproof layer 50 to improve the tightness of the core unit 10 inside the isolation area, improve the pressure resistance, prevent the loosening of the internal filler, and improve the internal waterproof effect. A waterproof filler 40 is arranged in the isolation area outside the core unit 10 and the filling strip 30, so that the interior reaches the corresponding waterproof level. The design of the isolation skeleton 20 and the filling strip 30 can make the internal structure of the network cable relatively stable and not easy to deform while improving the compressive strength of the network cable, thereby avoiding the damage of the external waterproof layer of the network cable due to deformation of the network cable. The axis seat 21 is arranged at the center of the isolation frame 20, and the bracket 22 is formed by extending outward from the axis seat 21. A plurality of brackets 22 are evenly distributed around the circumference of the axis seat 21. Preferably, the axis seat 21 and the bracket 22 are integrally formed.

[0034] The advantage of this embodiment is that the network cable with a waterproof structure uses the isolation frame 20 as a pressure-resistant support to make the interior of the network cable relatively stable, and ensures the waterproof performance of the network cable through external and internal waterproof structures. On the one hand, the outside is waterproofed by the first waterproof layer 50, the first insulating layer 60 and the sheath 70, and the inside is waterproofed by determining a stable structure through the limiting arrangement of the core unit 10, and the waterproof filler 40 and the isolation effect of the isolation frame 20 are used to achieve internal waterproofing, thereby reducing the risk of water seepage in the core unit 10.

[0035] In order to solve the problem that the internal waterproof structure of the network cable is not stable enough in the above solution, it is easy to deform and eventually lead to network cable damage and water leakage, please refer to Figure 1-3 Preferably, the isolation frame 20 adopts a triangular frame to optimize and improve its internal stability. Also preferably, the bracket 22 of the isolation frame 20 is provided with a limited arc groove 221 in the contact area with the wire core unit 10, and one end of the wire core unit 10 abuts against the limited arc groove 221 of the isolation frame 20, ensuring that the wire core unit 10 is sufficiently stable in the isolation area after abutting against the filling strip 30 to prevent deformation, ensure the filling effect of the waterproof filler 40, make it not easy to loosen and detach, and maintain the waterproof effect inside the network cable.

[0036] In order to solve the problem of poor waterproof effect inside the network cable in the current solution, please refer to Figure 1-3 Preferably, the waterproof filler 40 in this embodiment includes a waterproof potting glue, which can perform waterproof potting on the inside of the isolation frame 20 after the core unit 10 and the filling strip 30 are fixed in position, thereby improving the waterproof effect inside. Preferably, the filling strip 30 adopts a non-water-absorbing hard filling strip 30, which plays a role in stabilizing the relative positions of various components inside the isolation area and preventing water absorption and thus affecting the core unit 10 in the event of water seepage. In order to avoid the impact of water seepage inside the network cable on the core unit 10, a waterproof coating is applied to the outside of the core unit 10 to prevent water from entering the core unit 10.

[0037] Regarding the waterproof design of the core unit 10, please refer to Figure 1-3 Preferably, the wire core unit 10 includes a twisted pair core 11, and the twisted pair core 11 is wound with a second insulating layer 12 and a second waterproof layer 13 in sequence outwardly, and the twisted pair core 11 is filled with a waterproof yarn 14 in the second waterproof layer 13. Further preferably, the second waterproof layer 13 includes a semi-conductive water-blocking tape and a common water-blocking tape, and the semi-conductive water-blocking tape is wound on the outside of the second insulating layer 12, and the common water-blocking tape is wound on the semi-conductive water-blocking tape. The arrangement of the water-blocking tape further increases the waterproof strength of the network cable and improves the waterproof effect in the case of water seepage inside the network cable. In terms of materials, in this embodiment, the isolation frame 20 is made of ethylene propylene rubber, and the first insulating layer 60 and the second insulating layer 12 are made of lightweight polyvinyl chloride to improve the waterproof reliability of the product.
