Description

Technical Field

[0001] The invention relates to the technical field of wires, in particular to a tensile wire. Background Art

[0002] A cable is an electronic device used to transmit electrical signals, power or data. It consists of one or more insulated wires and is often wrapped in a protective layer. The structural design of the cable is to provide good electrical performance, mechanical strength and environmental protection to ensure effective signal transmission and reliable power delivery. Cables are widely used in various fields, including communications, construction, industry, energy, etc.

[0003] At present, conventional cables, whether data cables or power cables, are easily disconnected when stretched, bent, and especially bent due to their own structural design, making the device unable to work properly. For example, earphone cables have thinner wires inside. Once the internal wires break, the entire device cannot be used. Therefore, the present application proposes a tensile wire to at least partially solve the problems that may exist in the prior art. Summary of the invention

DETAILED DESCRIPTION

[0013] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0014] Embodiment 1 Reference Figures 1 to 4As shown, a tensile-resistant wire provided by an embodiment of the present invention includes: two groups of cables 104, one end of which is connected to the first interface 101; two groups of cables 104, wherein the other end of the first group is connected to the second interface 102; the other end of the second group is connected to the third interface 103; the cables 104 have an insulating layer 111 on the outside, and a plurality of wire cores 112 are arranged inside; the wire core 112 is composed of a tensile-resistant fiber 122 and at least one metal wire 121 wound on the tensile-resistant fiber 122.

[0015] In this embodiment, by providing a tensile fiber 122 in each core 112, when the cable 104 is subjected to tensile force, the tensile fiber 122 can withstand the main tensile force. For example, in daily use, if the cable 104 is accidentally pulled, the tensile fiber 122 will prevent the tensile force from directly acting on the metal wire 121, thereby reducing the risk of the metal wire 121 breaking due to stretching. Compared with traditional cables, the conductor inside the traditional cable usually does not have a special tensile structure, and is prone to direct breakage when subjected to a large tensile force. The tensile fiber 104 of the tensile wire of the present application can effectively disperse and withstand tensile force, protecting the wire from damage. The metal wire 121 in the above-mentioned core 112 is wound on the tensile fiber 122, and the structure has better stability when bending and bending. Due to the presence of the tensile fiber 122, the wire will not be excessively twisted or deformed during the bending process, reducing the possibility of breakage due to concentrated bending stress. For example, when the cable is bent at a certain angle, the tensile fiber 122 can serve as a supporting skeleton for the conductor, allowing the conductor to maintain a relatively stable shape and avoid excessive stress concentration points inside the conductor, thereby solving the problem of internal conductors of traditional cables being easily disconnected when bent and folded.

[0016] Specifically, by winding the metal wire 121 around the tensile fiber 122, the winding method allows the conductor to have a certain amount of expansion and contraction margin to a certain extent as the tensile fiber 122 stretches. When the tensile force acts, the conductor will not be immediately subjected to the entire tensile force, but will relieve the tensile force through relative displacement with the tensile fiber 122. For example, assuming that the tensile strength of the tensile fiber is X Newton, when subjected to a tensile force less than X Newton, the conductor may only slightly stretch around the tensile fiber 122 without breaking, thereby improving the overall tensile resistance of the cable and solving the problem that the internal conductor of the traditional cable is easily disconnected due to stretching.

[0017] On the other hand, since the metal wire 121 is wound on the tensile fiber 122 instead of being wound around each other or in parallel, when the conductor is bent or folded, the bending surface of the metal wire 121 is larger, so it is not easy to be broken, and when bending, the metal wire 121 that is also wound can also be released to relieve the tension. The insulating layer 111 on the outside of the metal wire 121 has a certain flexibility and elasticity, and can buffer the pressure on the core 112 during bending and folding to a certain extent. When the cable is bent or folded, the insulating layer 111 will deform first, dispersing part of the external force and reducing the direct pressure on the internal core 112. Compared with the insulating layer of an ordinary cable, the insulating layer 111 of the tensile conductor of the present application may be made of a more elastic and wear-resistant material, which can better adapt to frequent bending and folding operations.

[0018] For example, in the process of repeatedly bending and storing the headphone cable, the metal wire inside the ordinary headphone cable is easy to break, and the insulation layer may gradually age and crack, thereby causing the internal wires to be exposed and easily break. The tensile structure of the tensile wire of the present application combined with the insulating layer 111 can better protect the internal wire core 112 and extend the service life of the cable.

[0019] Embodiment 2 A tensile conductor, wherein each group of cables 104 contains at least one group of twisted pairs 141 formed by twisting two cables 104 , and at least one straight-through line of the cable 104 .

[0020] The above-mentioned twisted pair 141 is formed by twisting two cables 104, and its advantage is that it can effectively reduce the impact of external electromagnetic interference on signal transmission. When there is external electromagnetic noise, the interference signals sensed by the two twisted cables offset each other to a certain extent, thereby improving the stability and accuracy of signal transmission. For example, in an environment where many electronic devices are running, such as an office or a computer room, the electromagnetic radiation generated by various devices will interfere with the signal transmission in the cable. The structure of the twisted pair can reduce this interference and ensure the clear transmission of data or signals, which is particularly suitable for scenarios with high requirements for signal quality, such as data lines for high-speed data transmission.

[0021] The above straight-through cable can be used in some situations where direct connection is required, the signal transmission path is relatively simple and is not sensitive to interference, and it can also increase the flexibility of cable layout. It can meet the interface and connection requirements of different devices, and cooperate with twisted pair cables to ensure that the cable has a good signal transmission effect in different application scenarios.

[0022] As a preferred implementation, the middle portion between the two groups of cables 104 is coated with an anti-wear tape 106 to form a wiring harness.

[0023] Furthermore, the anti-wear tape 106 is acetate cloth. The acetate cloth tape is made of imported high-quality acetate fiber cloth as the base material and coated with acrylic flame retardant adhesive; it has the characteristics of high temperature resistance, solvent resistance, aging resistance, good insulation, flame retardancy, high viscosity, etc., and has the characteristics of stable and reliable performance.

[0024] As a preferred embodiment, the insulating layer 111 has a thickness of 0.21-0.25 mm and an outer diameter of 0.8-1 mm, and is made of PVC or PE material. Among them, PVC (polyvinyl chloride) and PE (polyethylene) are both excellent insulating materials. It can effectively prevent current leakage and ensure the electrical safety of the cable during use. Whether in normal working conditions or in some special environments, it can ensure that the current is stably transmitted in the wire inside the cable, prevent the risk of electric shock to the user, and provide basic protection for the safe operation of the equipment. For example, in a household power environment, using a cable with such an insulating layer to connect electrical equipment can effectively avoid leakage accidents caused by poor cable insulation and protect the lives of family members. The thickness of the insulating layer 111 is in the range of 0.21-0.25 mm, which can provide a certain degree of mechanical protection for the internal core 112. This thickness will not be too thick to make the cable stiff and difficult to bend, and can effectively prevent damage to the internal core 112 by slight scratches and wear on the outside. In daily use, the cable may come into contact with various objects, such as desktops, clothing, etc. The insulation layer of appropriate thickness can protect the wire core 112 from these daily frictions and collisions, thereby extending the service life of the cable. The outer diameter of 0.8-1mm allows the single cable 104 to maintain a relatively thin structure, and the tensile wire composed of multiple strands of cables 104 does not occupy too much volume of the device, which is conducive to flexible wiring of the device.

[0025] As a preferred embodiment, the twisted outer diameter of the wire core 112 is 0.305 mm, wherein the metal wire 121 is an annealed tinned copper wire. The twisted outer diameter of the above-mentioned wire core 112 is the comprehensive outer diameter of the metal wire 121 after being wound around the tensile fiber 122, so that the wire core 112 has good flexibility. In daily use, cables need to be bent and twisted frequently, and a smaller outer diameter can make the cables more easily adapt to various complex shape changes. For example, in application scenarios such as headphone cables or mobile phone charging cables, users may frequently bend and store the cables. This thinner wire core can better withstand these operations and reduce the risk of damage to the internal wires due to bending.

[0026] In the present application, copper is an excellent conductive material with low resistance. Annealing can further reduce the hardness of the copper wire and improve its flexibility and conductivity. The annealed tinned copper wire can reduce resistance loss and improve the transmission efficiency of electric energy during current transmission. This is very important for cables that need to efficiently transmit electric energy or signals, which can reduce the energy consumption of the equipment and improve the working efficiency of the equipment. For example, in some electronic devices with strict power consumption requirements, such as smart phones, laptops, etc., using annealed tinned copper wire as the core can reduce energy loss during charging, speed up charging, and also ensure the stability and accuracy of signal transmission during operation of the device.
