Description

Technical Field

[0001] The present application relates to the field of cable technology, and in particular to a moving communication cable, a moving communication cable. Background Art

[0002] When sports communication cables in the prior art are manufactured, the core wires are often not twisted or the core wire groups have the same twist pitch when cabled. The cable core wire groups and core wire settings in the prior art may cause crosstalk between cable signals; and the signals are easily interfered with at low frequencies or near magnetic fields, especially in long-term motion application scenarios or low temperature, oily environments, etc., which may cause the cable to crack or break. Utility Model Content

[0003] In order to solve the above technical problems, the present application provides a motion communication cable, comprising a first protective layer arranged on the outer circumference of the cable; a first shielding layer arranged inside the first protective layer; a wire pair arranged inside the first shielding layer, a plurality of the wire pairs are twisted along a first direction; the wire pair comprises at least two core wires, at least two of the core wires are twisted along a second direction; the core wire comprises an insulating layer and a plurality of conductors, a plurality of the conductors are twisted along the second direction. At least two of the core wires are twisted in pairs along the second direction to form a wire pair, and a plurality of the wire pairs are twisted into a cable along the first direction. Through the above arrangement, the internal stress generated when the core wires are evenly arranged in a spiral shape to form a cable is eliminated, avoiding their own rotation while maintaining their own flexibility, thereby improving the stability of the cable in long-term motion scenarios.

[0004] Preferably, the plurality of conductors are twisted at a pitch of 5-7 mm along the second direction, and the conductors are made of Category 6 or above copper wire conductors. The conductors are made of Category 6 or above ultra-fine copper wires, which can reduce the finished wire diameter and thus reduce the wire bending radius; the conductors are twisted at a pitch of 5-7 mm, and the conductor structure is stable; through the above settings, the motion communication cable of this scheme can be better suited for long-term mobile applications.

[0005] Preferably, at least two of the core wires in different pairs are twisted with different pitches. Different pairs are twisted with different pitches, and each pair of signals is transmitted separately and staggered, so that no superimposed crosstalk interference is generated; at the same time, the twisted pitches of the pairs are different, with different pitch-diameter ratios and back-twist rates, so that the pairs have better tensile strength and meet the requirements of long-term mobile applications.

[0006] Preferably, the invention further comprises a filler, the filler is arranged inside the first protective layer and the first shielding layer, and the filler is a fiber filler. The high-strength fiber filler is used to ensure the softness of the product while improving the tensile strength of the product, thereby avoiding the problem of damage to the conductor and the insulation layer due to excessive stretching.

[0007] Preferably, the cable further comprises a second protective layer, which is arranged inside the first shielding layer. By arranging multiple protective layers, the high-strength protective layer further improves the tensile strength of the cable.

[0008] Preferably, a second shielding layer is further included, the second shielding layer is arranged inside the second protective layer, the second shielding layer has a gap, and at least a portion of the second protective layer is embedded in the gap of the second shielding layer. By setting multiple shielding layers, a better shielding effect is achieved. At the same time, the second protective layer is made of polyolefin material, the polyolefin material has a certain elasticity, and the second protective layer material is embedded in the gap of the inner shielding to ensure that the braided structure in the second shielding layer is not loose under long-term movement. Furthermore, the optimized braiding angle of the second shielding layer enables the shielding layer to tightly wrap the wire pair and filler, and will not become loose and fail under long-term mobile applications, and also has a better shielding effect.

[0009] Preferably, the first shielding layer is composed of tinned copper wire, and the single wire diameter of the tinned copper wire is between 0.08mm and 0.12mm. The first shielding layer uses tinned copper wire with a larger wire diameter to avoid the problem of wire breakage due to the copper wire being too thin during long-term use. The tinned copper wire has good softness and strength.

[0010] Preferably, the second shielding layer is composed of galvanized steel wire, and the single wire diameter of the galvanized steel wire is less than or equal to 0.08 mm. The second shielding layer is arranged in the first shielding layer. The smaller wire diameter of the inner shielding layer can ensure the flexibility of the wire. The nickel-plated steel wire can shield the interference of the magnetic field, and the shielding effect in the low-frequency electric field is better than that of copper wire.

[0011] Preferably, the insulating layer is made of polyolefin material. The insulating layer polyolefin material has excellent electrical properties, can minimize the loss of signal transmission, and has excellent tensile strength and high and low temperature tolerance.

[0012] Preferably, the first protective layer is made of polyurethane material. Polyurethane material has excellent fatigue resistance, impact resistance, high wear resistance, high bending modulus and high strength mechanical and physical properties, which can make the finished cable have excellent resilience and a small bending radius, greatly improving the reliability of cable mobile applications. At the same time, polyurethane material has excellent high and low temperature characteristics, oil resistance, acid and alkali resistance, and can be widely used in different scenarios.

[0013] As can be seen from the above, the application of this application can at least achieve the following beneficial effects:

[0014] (1) By twisting the core wires in the second direction to form wire pairs, and twisting the wire pairs in the first direction to form cables, the internal stress generated when the core wires are evenly arranged in a spiral shape to form cables is eliminated, thereby avoiding their own rotation while maintaining their own flexibility, thereby improving the stability of the cable in long-term motion scenarios.

[0015] (2) Multiple shielding layers and protective layers are set up to further enhance the cable's tensile strength in long-term motion scenarios and its ability to shield signal interference. BRIEF DESCRIPTION OF THE DRAWINGS

At least two core wires 40 are twisted in pairs along the second direction to form a wire pair 50, and a plurality of wire pairs 50 are twisted into a cable along the first direction. Through the above arrangement, the internal stress generated when the core wires 40 are uniformly arranged in a spiral shape into a cable is eliminated, avoiding their own rotation, while maintaining their own flexibility, thereby improving the stability of the cable in long-term motion scenarios.

[0023] Furthermore, multiple conductors 20 are twisted along the second direction with a pitch of 5-7mm, and the conductors 20 use Category 6 or above copper wire conductors. At this time, the twisting direction of the conductors 20 is the same as the twisting direction of the core wires 40, and the conductors 20 move in one direction; the conductors are twisted with a pitch of 5-7mm, and the conductor structure is stable. The conductors use Category 6 or above ultra-fine copper wires, which can reduce the finished wire diameter and thus reduce the wire bending radius. Through the above settings, the motion communication cable of this scheme can be better suited for long-term mobile applications.

[0024] Furthermore, the cable 10 includes a plurality of wire pairs 50, each wire pair 50 is composed of at least two core wires 40, and at least two core wires 40 in different wire pairs 50 are twisted at different pitches. Different wire pairs 50 are twisted at different pitches, and each pair of signals is transmitted separately and staggered, so that no superimposed crosstalk interference is generated; at the same time, the wire pairs 50 have different twisting pitches, different pitch-diameter ratios and back-twist rates, so they have better tensile strength and meet long-term mobile applications.

[0025] Furthermore, the invention also includes a filler 60, which is disposed inside the first protective layer 1000 and the first shielding layer 90, and is a fiber filler. The high-strength fiber filler 60 ensures the softness of the product while improving the tensile strength of the product, thereby avoiding the problem of damage to the conductor and the insulation layer due to excessive stretching.

[0026] Furthermore, it also includes a second protective layer 80, which is arranged inside the first shielding layer 90. By arranging multiple protective layers, the high-strength protective layer further improves the tensile strength of the cable.

The second shielding layer 70 is formed by weaving a filamentary material, and the diameter of the single wire of the braided body is less than or equal to 0.08 mm. A gap is formed in the braided body of the second shielding layer 70. The second protective layer 80 is made of polyolefin material, which has a certain elasticity, and at least a part of the second protective layer 80 is embedded in the gap of the second shielding layer. By setting multiple shielding layers, a better shielding effect is achieved. At the same time, the material of the second protective layer 80 is embedded in the gap of the internal second shielding layer 70 to ensure that the braided structure in the second shielding layer 70 is not loose under long-term movement. Furthermore, the optimized braiding angle of the second shielding layer 70 enables the shielding layer to tightly wrap the wire 50 pair and the filler 60, and it will not become loose and fail under long-term mobile applications.

The first shielding layer 90 uses tinned copper wire with a larger wire diameter to avoid the problem of wire breakage due to the copper wire being too thin during long-term use. The tinned copper wire has good softness and strength.

[0029] Furthermore, the second shielding layer 70 is composed of galvanized steel wire, and the single wire diameter of the galvanized steel wire is less than or equal to 0.08 mm. The second shielding layer 70 is arranged in the first shielding layer 90. The smaller wire diameter of the inner shielding layer can ensure the flexibility of the wire. The nickel-plated steel wire can shield the interference of the magnetic field, and the shielding effect in the low-frequency electric field is better than that of copper wire.

[0030] Furthermore, the insulating layer 30 is made of polyolefin material. The polyolefin material of the insulating layer 30 has excellent electrical properties, can minimize the loss of signal transmission, and has excellent tensile strength and high and low temperature tolerance.

[0031] Furthermore, the first protective layer 100 is made of polyurethane material.
