Description

Technical Field

[0001] This utility model relates to the field of coaxial cables, specifically to a multi-channel, highly flexible, temperature-resistant, and interference-resistant coaxial cable. Background Technology

[0002] Broadband coaxial cables, used for data communication and high-definition video transmission, typically form the channel for information transmission. They can be categorized based on laying conditions, operating conditions, transmission spectrum, cable core structure, and insulation materials. They require good impedance characteristics, electrical insulation, and stability, making them a standard transmission carrier for cable television networks and security monitoring systems. However, traditional data network cables are mostly made and used in single pairs, leading to scattered and disorganized wiring for large local area network base stations and security control systems. Furthermore, ordinary cables generally have poor torsional resistance, exhibiting poor flexibility and reduced tensile strength in indoor and outdoor environments. After being subjected to varying degrees of twisting and bending, the conductor core bears torsional stress, making them prone to defects.

[0003] Copper wire deformation and breakage are common problems, and the shielding layer is prone to cracking and the cable sheath is prone to cracking, affecting electrical characteristics. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a multi-channel, highly flexible, temperature-resistant, and interference-resistant coaxial cable to solve the above-mentioned problems.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a multi-channel, highly flexible, temperature-resistant, and interference-resistant coaxial cable, comprising a single coaxial cable, a diamond-shaped bracket, an extended ring frame, an outer ring frame, a polyester cable tie layer, an outer shielding layer, and an outer protective layer; several of the single coaxial cables are twisted together around the diamond-shaped bracket; both ends of the extended ring frame are fixedly connected to the diamond-shaped bracket, and together with the diamond-shaped bracket, they form a circular cavity that encloses the single coaxial cable; the outer ring frame is limited and installed on the outside of the extended ring frame, and is limited and abuts against each extended ring frame; the outer ring frame is covered with a polyester cable tie layer, the outer side of the polyester cable tie layer is covered with an outer shielding layer, and the outer side of the outer shielding layer is covered with an outer protective layer.

[0006] Preferably, the single coaxial cable is provided with a second cable core, an aluminum-plastic composite tape layer, an inner shielding layer and an inner protective layer arranged sequentially from the inside to the outside. The second cable core includes a cross skeleton and multiple sets of insulated wire cores located in four areas formed by the cross skeleton, and the multiple sets of insulated wire cores are twisted together around the cross skeleton.

[0007] Preferably, the inner side of the outer annular frame protrudes inward to form a limiting protrusion, and the extended annular frame is recessed inward to form a limiting groove corresponding to the limiting protrusion.

[0008] Preferably, the insulated core includes a conductor and an inner insulation layer wrapped around the conductor; the conductor is an annealed soft copper conductor, and the inner insulation layer is a polyethylene insulating material.

[0009] Preferably, both the outer shielding layer and the inner shielding layer are made of tin-plated copper wire.

[0010] Preferably, the outer protective layer is made of flexible TPE material, and the inner protective layer is made of LDPE material.

[0011] Preferably, the polyester cable tie layer has an overlapping and wrapping structure.

[0012] Preferably, the aluminum-plastic composite strip layer has a longitudinal wrapping structure.

[0013] The main technical effects of this utility model are as follows: By extending the ring frame and enclosing the single coaxial cable with the diamond-shaped bracket, the friction between the single coaxial cable and the polyester cable tie layer is reduced. This allows the single coaxial cable to rotate relative to the diamond-shaped bracket and the extended ring frame when the cable undergoes varying degrees of twisting and bending and the conductor core is subjected to torsional stress, thereby reducing torsional stress. Furthermore, the limiting contact between the outer ring frame and the extended ring frame also allows the coaxial cable to reduce torsional stress through relative rotation between the extended ring frame and the outer ring frame, thus preventing copper wire deformation and breakage, as well as shielding layer breakage and cable sheath cracking, ensuring electrical characteristics.

Detailed Implementation

[0017] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.

[0018] In this embodiment, it should be understood that the terms "middle," "upper," "lower," "top," "right side," "left end," "above," "back," "center," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0019] Furthermore, unless otherwise specified in this specific embodiment, the connection or fixing method between components can be achieved by bolt fixing, pin fixing, or pin connection commonly used in the prior art. Therefore, it will not be described in detail in this embodiment.

[0020] This utility model provides a multi-channel, highly flexible, temperature-resistant, and interference-resistant coaxial cable, such as... Figure 1-2 As shown, the structure includes a single coaxial cable 1, a diamond-shaped bracket 2, an extended ring frame 3, an outer ring frame 4, a polyester cable tie layer 5, an outer shielding layer 6, and an outer protective layer 7. Several single coaxial cables 1 are twisted together around the diamond-shaped bracket 2. Both ends of the extended ring frame 3 are fixedly connected to the diamond-shaped bracket 2, forming a circular cavity that encloses the single coaxial cable 1. The outer ring frame 4 is positioned and installed on the outside of the extended ring frame 3, and abuts against each extended ring frame 3. The outer ring frame 4 is covered with a polyester cable tie layer 5, and the outer side of the polyester cable tie layer 5 is covered with an outer shielding layer 6. The cable is covered with an outer protective layer 7. The single coaxial cable 1 is encased by the extended ring frame 3 and the diamond bracket 2, which reduces the friction between the single coaxial cable 1 and the polyester cable tie layer 5. This allows the single coaxial cable 1 to rotate relative to the diamond bracket 2 and the extended ring frame 3 when the cable is subjected to different degrees of twisting and bending and the conductor core is subjected to torsional stress, thereby reducing the torsional stress. Furthermore, the limiting contact between the outer ring frame 4 and the extended ring frame 3 also allows the coaxial cable to reduce torsional stress through relative rotation between the extended ring frame 3 and the outer ring frame 4, thereby preventing copper wire deformation and breakage, as well as shielding layer breakage and cable sheath cracking, ensuring electrical characteristics.

[0021] Preferably, the single coaxial cable 1 is provided with a second cable core 11, an aluminum-plastic composite tape 12 layers, an inner shielding layer 13, and an inner protective layer 14 arranged sequentially from the inside to the outside. The second cable core 11 includes a cross skeleton 111 and multiple sets of insulated wire cores 112 arranged in four areas formed by the cross skeleton 111, and the multiple sets of insulated wire cores are twisted together around the cross skeleton 111. Compared with the single-pair manufacturing of traditional cables, this avoids the disadvantage of scattered and messy wiring when the cable is used.

[0022] Preferably, the inner side of the outer annular frame 4 protrudes inward to form a limiting protrusion 41, and the extended annular frame 3 is recessed inward to form a limiting groove corresponding to the limiting protrusion 41, so as to prevent the extended annular frame 3 from slipping off the outer annular frame 4.

[0023] Preferably, the insulated core includes a conductor and an inner insulation layer wrapped around the conductor; the conductor is an annealed soft copper conductor, and the inner insulation layer is a polyethylene insulating material.

[0024] Preferably, both the outer shielding layer 6 and the inner shielding layer 13 are made of tin-plated copper wire braid, which can effectively shield external electromagnetic interference.

[0025] Preferably, the outer protective layer 7 is made of flexible TPE material to enhance the cable's temperature resistance, flame retardancy, scratch resistance, and cut resistance, while the inner protective layer 14 is made of LDPE material.

[0026] Preferably, the polyester cable tie layer 5 has an overlapping and wrapping structure. The polyester cable tie layer 5 has good shrinkage and toughness, which can ensure that the cable is tied more securely and make the cable more round.

[0027] Preferably, the 12-layer aluminum-plastic composite strip has a longitudinal wrapping structure, which serves to provide insulation, heat insulation, thermal insulation, and corrosion protection.

[0028] The main technical effects of this utility model are as follows: By extending the ring frame and enclosing the single coaxial cable with the diamond-shaped bracket, the friction between the single coaxial cable and the polyester cable tie layer is reduced. This allows the single coaxial cable to rotate relative to the diamond-shaped bracket and the extended ring frame when the cable undergoes varying degrees of twisting and bending and the conductor core is subjected to torsional stress, thereby reducing torsional stress. Furthermore, the limiting contact between the outer ring frame and the extended ring frame also allows the coaxial cable to reduce torsional stress through relative rotation between the extended ring frame and the outer ring frame, thus preventing copper wire deformation and breakage, as well as shielding layer breakage and cable sheath cracking, ensuring electrical characteristics.

[0029] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
