Description

Technical Field

[0001] The utility model relates to the field of communication network cables, in particular to a bending-resistant network cable. Background Art

[0002] Nowadays, electronic transmission and control are commonly used and indispensable. Signals between terminals need to be transmitted by wire. Network cables are one of the most commonly used connecting cables. In an environment where the network cable layout needs to be changed frequently, the network cables are often rolled up first, and then laid out according to the design and planning. During operation, the network cables are easily cracked and broken due to bending, squeezing and pulling.

[0003] When using the signal network cable, the plug must be connected to the socket of the relevant communication component. Since the wiring settings are mostly bent and used many times, they will inevitably be pulled and bent by the outside world. Therefore, the network cable generally needs to have a certain flexibility to adapt to the external bending force. However, once the external force is large and the action time is long, the network cable will be subjected to long-term and large bending, and the network cable itself has limited anti-bending performance, it will cause the network cable to bend excessively and it will be difficult to restore its original shape, causing the internal conductive core to crack and be damaged due to bending, making the network cable unable to be used normally. Therefore, the wire core inside the network cable is prone to breakage. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-bending type network cable, comprising a limiting cylinder, one side surface of the limiting cylinder is a hollow through structure, a guide groove is provided at one edge of the outer arc surface of the limiting cylinder, positioning grooves are provided on both sides of the inner arc surface of the limiting cylinder close to the guide groove, and an anti-bending component is movably sleeved in the inner hollow structure of the limiting cylinder;

[0006] The anti-bending component includes a positioning rib movably sleeved on the inner arc surface of the limiting cylinder, the edge of one side of the outer arc surface of the positioning rib is an elastic structure, protrusions are provided on both sides of the outer arc surface of the positioning rib, the outer arc surface of the protrusion is movably engaged with the positioning groove, one side surface of the positioning rib is connected to the hollow structure of the limiting cylinder, the inner arc surface of the positioning rib is movably sleeved with a reinforcing rib, the inner arc surface of the reinforcing rib is provided with a connecting seat, and the angle range between the lead grooves of the connected positioning ribs is 30° to 60°, thereby limiting the bending radius of the network cable and avoiding excessive bending.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] See also Figure 1-6In the figure, a bending-resistant network cable includes a limiting cylinder 1, one side surface of the limiting cylinder 1 is a hollow through structure, a guide groove 2 is provided at one edge of the outer arc surface of the limiting cylinder 1, and positioning grooves 3 are provided on both sides of the inner arc surface of the limiting cylinder 1 near the guide groove 2. An anti-bending component 4 is movably sleeved in the internal hollow structure of the limiting cylinder 1, and the anti-bending component 4 includes a positioning rib 401 movably sleeved on the inner arc surface of the limiting cylinder 1, and the outer arc surface of the positioning rib 401 has an elastic structure on one side edge. Protrusions 402 are provided on both sides of the outer arc surface, and the outer arc surface of the protrusion 402 is movably connected with the positioning groove 3. One side surface of the positioning rib 401 is connected to the hollow structure of the limiting cylinder 1. The inner arc surface of the positioning rib 401 is movably sleeved with a reinforcing rib 403. The inner arc surface of the reinforcing rib 403 is provided with a connecting seat 404. A coil spring 405 is fixedly installed on one side surface of the connecting seat 404. The coil spring 405 penetrates into the interior of the limiting cylinder 1, and the inner arc surface of the reinforcing rib 403 is penetrated and connected with the outer sheath 5 of the network cable.

[0020] In this embodiment: wherein, the raised portions 402 on both sides of the positioning rib 401 are movably clamped in the positioning grooves 3 on both sides of the inner arc surface of the limiting cylinder 1. Since a lead groove 2 is provided on the top of the outer arc surface of the limiting cylinder 1, the angle range between the lead grooves 2 of the connected positioning rib 401 is 30° to 60°, thereby limiting the bending radius of the network cable and avoiding excessive bending. The purpose of fixing the reinforcing rib 403 on the front end of the inner arc surface of the connected positioning rib 401 is to improve the original toughness of the network cable after the network cable is penetrated.

[0021] Secondly, a coil spring 405 is sleeved on the outer arc surface of the network cable, and the anti-deformation force of the coil spring 405 provides the network cable with further anti-bending ability, so that the network cable can quickly recover to a straight state through the elasticity of the coil spring 405 after bending. When the bending force disappears, the rotating belt automatically contracts to drive the coil spring 405 to rotate, changing the bending direction of the coil spring 405, thereby achieving further correction of the bending of the network cable through the change of the bending direction of the coil spring 405, and it has its own rigidity and elastic recovery effect.

[0022] Example 2

[0023] See also Figure 3 The present embodiment further explains Example 1. In the figure, the outer sheath 5 of the network cable is made of rubber, the inner arc surface of the outer sheath 5 of the network cable is provided with a reinforcing core 6, the inner arc surface of the reinforcing core 6 is provided with a network stranded wire 7, the outer arc surface of the network stranded wire 7 is provided with a protective layer 8, a buffer filling layer 9 is provided between the network stranded wire 7 and the reinforcing core 6, the reinforcing core 6 is an elastic hard material, the diameter of the outer sheath 5 of the network cable is less than 0.07 mm, the protective layer 8 is embedded in the buffer filling layer 9 as a whole, the outer sheath 5 of the network cable penetrates the interior of the limiting cylinder 1 as a whole, and the network stranded wires 7 are isolated and filled with a buffer filling layer 9.

[0024] In the present embodiment: wherein, the network cable outer sheath 5 adopts Indonesian dragon to reduce the weight of the network cable, a plurality of network strands 7 are evenly distributed outside the reinforcing core 6, and a buffer filling layer 9 is provided between the network strands 7 to isolate and fill the inside so that a solid whole is formed, and the buffer filling layer 9 is wrapped with an external protective layer 8. The reinforcing core 6 plays a connecting role, which not only protects the top network cable outer sheath 5, but also the bottom network strands 7. The reinforcing core 6 has good ductility and is not easily broken when the network cable assembly is bent, thereby improving the bending resistance of the network cable assembly and solving the problem that the core 1 inside the network cable is easily broken.

[0025] Secondly, because the slow-release reinforcing core 6 is a cylindrical iron material similar to iron wire in the network cable, the network strands 7 are placed in the bundle tube, wound around the reinforcing core 6, and then a filling tube is added, and then bundled, and then other materials and outer skins are added to make the network cable. This makes the network cable have tensile and bending resistance, preventing the internal optical fiber from being broken and damaged by external forces when the network cable is connected.

[0026] Example 3

[0027] See also Figures 1 to 4 In this embodiment, the raised portions 402 on both sides of the positioning rib 401 are movably connected to the positioning grooves 3 on both sides of the inner arc surface of the limiting cylinder 1. Since the top of the outer arc surface of the limiting cylinder 1 is provided with a lead groove 2, the angle range between the connected positioning rib 401 and the lead groove 2 is 30° to 60°, thereby limiting the bending radius of the network cable and avoiding excessive bending. The reinforcing rib 403 is fixed to the front end of the inner arc surface of the connected positioning rib 401. Its purpose is to improve the original toughness of the network cable after it passes through and protect the network cable. The coil spring 405 is sleeved on the outer arc surface of the network cable. The anti-deformation force of the coil spring 405 provides the network cable with further anti-bending ability, so that the network cable can quickly recover to a straight state through the elasticity of the coil spring 405 after bending. When the bending force disappears, the rotary belt automatically retracts. The contraction drives the coil spring 405 to rotate, and changes the bending direction of the coil spring 405, so as to further correct the bending of the network cable by changing the bending direction of the coil spring 405. It has its own rigidity and elastic recovery effect. The outer sheath 5 of the network cable adopts Indonesian dragon to reduce the weight of the network cable. A plurality of network strands 7 are evenly distributed outside the reinforcing core 6. The network strands 7 are isolated and filled with a buffer filling layer 9 to form a solid whole inside. The buffer filling layer 9 is wrapped with an external protective layer 8. The reinforcing core 6 plays a connecting role, which not only protects the top network cable outer sheath 5, but also the bottom network strands 7. The reinforcing core 6 has good ductility and is not easily broken when the network cable assembly is bent, thereby improving the bending resistance of the network cable assembly and solving the problem that the core 1 inside the network cable is easily broken.
