Description

Technical Field

[0001] This utility model relates to the field of flexible reinforcing network cables, and more particularly to flexible reinforcing network cables that are resistant to bending and easy to install. Background Technology

[0002] In the field of modern network communication, network cables serve as a crucial carrier for data transmission, and their performance directly impacts communication quality and stability. With the continuous expansion of network application scenarios, network cables need to adapt to various complex environments such as homes, offices, and industrial control systems, frequently facing external forces such as bending, compression, and dragging.

[0003] Current network cable technology mostly adopts a structural design that uses a single sheath layer to wrap the internal conductors. Its technical principle mainly relies on the basic physical properties of the sheath material to provide protection. Typically, polyvinyl chloride or polyethylene is used as the outer sheath, and multiple insulated copper wires are arranged in a certain twisting pattern inside. Some network cables add simple filler rope between the sheath and the conductors to reduce friction between the conductors.

[0004] Traditional network cables often suffer from problems such as broken internal copper wires and unstable signal transmission due to frequent bending, squeezing, or dragging during use. Especially in home wiring, office settings, or temporary outdoor deployments, network cables need to adapt to complex environments and bending angles. Ordinary network cables have insufficient bending resistance, which can easily lead to shortened lifespan and increased maintenance costs. Utility Model Content

[0031] Reference Figure 1 and Figure 2 One embodiment of this utility model provides: a flexible, resilient network cable that is resistant to bending and easy to install, comprising:

[0032] The outer wall protective layer 1 is used to resist external friction and compression, thereby forming a rigid protective combination with the support layer 3, reducing the risk of surface wear of the network cable during the laying process. The inner wall of the outer wall protective layer 1 is provided with the support layer 3, and the support layer 3 is provided with reinforcing ribs 2. The reinforcing ribs 2 work with the support layer 3 to disperse stress. The reinforcing ribs 2 distributed in a ring array form a multi-point support structure when bending, which achieves the effect of decomposing the concentrated bending force into multiple directional components. The reinforcing ribs 2 are used to resist bending.

[0033] The support layer 3 has a flexible layer 4 on its inner wall. The flexible layer 4 has rhomboid openings 6 inside. The rhomboid openings 6 are used to disperse bending stress. The rhomboid structure arranged laterally deforms and absorbs energy when subjected to force, thus realizing the effect of transforming local concentrated stress into uniformly distributed stress. The rhomboid openings 6 are used to disperse bending stress.

[0034] Flexible layer 4 has an inner wall with a filling layer 5 made of aramid fiber braiding. The filling layer 5 provides elastic cushioning and fixes the position of the copper wires. Its triangularly distributed placement holes 7 limit copper wire displacement, a common technique in the cable industry, which will not be elaborated further here. The filling layer 5 has placement holes 7 inside. A support layer 3 is fixedly connected to the inner wall of the outer protective layer 1. The support layer 3 is made of high-density polyethylene and works with the flexible layer 4 to buffer deformation, achieving a layer-by-layer attenuation of bending stress. This material combination is a standard choice in the communication cable industry, and will not be elaborated further here. The inner wall of the support layer 3 is fixedly connected with a flexible... Layer 4, the flexible layer 4 is made of thermoplastic polyurethane elastomer material, which serves as a transition layer between rigid protection and flexible buffer. Its diamond-shaped opening 6 structure design is a well-known technology in the field of stress dispersion, and will not be described in detail here. The inner wall of the support layer 3 is fixedly connected with reinforcing ribs 2, which are distributed in a ring array inside the support layer 3. The flexible layer 4 has diamond-shaped openings 6 inside, which are horizontally staggered inside the flexible layer 4. The flexible layer 4 is fixedly connected with a filling layer 5, which has placement holes 7 inside. The placement holes 7 are distributed in a triangle inside the filling layer 5 and are used to support copper wires.

[0035] Working principle: When the network cable is under stress, the outermost protective layer 1 first resists external friction and compression, forming a rigid protective combination with the inner support layer 3. The reinforcing ribs 2, arranged in a ring array inside the support layer 3, can disperse the bending impact force through multiple points of force application. When the network cable bends, the reinforcing ribs 2 limit excessive deformation with their own structural strength, preventing cracks in the outer structure due to bending. At the same time, the fixed connection structure between the support layer 3 and the flexible layer 4 ensures that external forces can be transmitted and buffered layer by layer, reducing the stress directly acting on the core copper wire. Inside the flexible layer 4, the horizontally intersecting diamond-shaped openings... Hole 6 plays a key role in stress dispersion: During bending, the rhomboid structure absorbs energy through the deformation of its edges and corners, decomposing concentrated stress into dispersed forces in multiple directions, thus preventing structural damage caused by stress overload in local areas. The triangular placement holes 7 in the inner filling layer 5 provide stable support for the copper wire. The geometric stability of the triangle can limit the displacement of the copper wire during bending. Combined with the elastic buffer of the fiber material, it further reduces fatigue damage to the copper wire caused by repeated bending, ultimately achieving the synergistic anti-bending effect of the multi-layer structure of outer protective layer 1, support layer 3, flexible layer 4 and filling layer 5.
