Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a combined coaxial cable. Background Technology

[0002] Currently, the connecting cables used in wired transmission networks are basically installed using a dedicated cable model, that is, power lines, coaxial cables, and audio lines are all installed separately. This installation method makes the connecting cables very complicated, which is not conducive to maintenance and line management. Furthermore, due to the lack of uniformity in the color of connecting cables on the market and the inconsistent lengths reserved for maintenance during installation, it leads to disharmony in the indoor aesthetics and greatly increases the construction and laying costs. In addition, these connecting cables are produced and packaged separately in the factory, which increases production costs and thus increases the customer's procurement costs.

[0003] In the prior art, a utility model patent with patent application number CN200820050826.9 discloses a combined coaxial cable, including a single cable wire, a signal wire, an audio wire, a power wire, and a general sheath. The single cable wire, the signal wire, the audio wire, and the power wire are all wrapped inside the general sheath, which realizes the combination of the single cable wire, the signal wire, the audio wire, and the power wire together. However, the shielding performance of this structure is insufficient, which can easily cause electromagnetic interference to the single cable wire. Utility Model Content

[0004] The main objective of this invention is to propose a combined coaxial cable, which aims to solve the technical problems in the background art.

[0005] To achieve the above objectives, this utility model proposes a combined coaxial cable, comprising a cable, a signal line, an audio line, a power line, and a protective sheath. The cable, signal line, audio line, and power line are all housed within the protective sheath. The cable is located at the center of the protective sheath's cross-section. The signal line, audio line, and power line are respectively positioned at three equal points on the outer periphery of the cable. The gaps between the signal line, audio line, and power line are filled with flexible material. The cable comprises a center conductor, an insulation layer, an inner shielding layer, an inner sheath, an outer shielding layer, and an outer sheath. The center conductor, insulation layer, inner shielding layer, inner sheath, outer shielding layer, and outer sheath are arranged radially from the inside out.

[0006] Preferably, the signal line includes a pair of first core wires, two first shielding layers, and a first protective layer. The first shielding layers are respectively wrapped around the outside of the first core wires, and the first shielding layers and the pair of first core wires are all embedded in the first protective layer.

[0007] Preferably, the audio cable includes a second core wire, a second shielding layer, and a second protective layer, wherein the second core wire, the second shielding layer, and the second protective layer are arranged radially in sequence.

[0008] Preferably, the flexible material is made of butyl rubber.

[0009] Preferably, the butyl rubber contains a plurality of micro-metal particles uniformly disposed therein.

[0010] Preferably, a third shielding layer is fixed on the inner circumference of the protective sleeve.

[0011] The technical solution of this utility model has the following beneficial effects: By setting two shielding layers on the outside of the central conductor of the cable and isolating them with an inner sheath, a better shielding effect is achieved. Complete isolation between the inner and outer shielding layers is also achieved, increasing compressive strength. Separating the signal line, audio line, and power line at three equal points on the outer periphery of the cable reduces electromagnetic interference and increases structural stability. The flexible material provides support and fixation while also making the entire combined coaxial cable easy to bend. Since the individual cable lines, signal lines, audio lines, and power lines are all wrapped inside the overall sheath, the cable can function as a multi-functional cable, simultaneously transmitting digital or analog high-frequency signals, signal transmission feedback or control, audio information, and power transmission. Users will find the coaxial cable easy to install and does not affect the aesthetics of the room after installation. Attached Figure Description

[0020] This utility model proposes a combined coaxial cable.

[0021] like Figure 1As shown in one embodiment of this utility model, the combined coaxial cable includes a cable, a signal line 8, an audio line 10, a power line 9, and a protective sleeve 1. The cable, signal line 8, audio line 10, and power line 9 are all housed within the protective sleeve 1. The cable is located at the center of the cross-section of the protective sleeve 1. The signal line 8, audio line 10, and power line 9 are respectively positioned at three equal points on the outer periphery of the cable, forming an equilateral triangle structure. The signal line 8, audio line 10, and power line 9 can all abut against the outer side of the cable, or they can have a certain gap. The gaps between the signal line 8, audio line 10, and power line 9 are filled with flexible material, connecting the protective sleeve 1 to the cable. The remaining gaps are completely filled. The cable includes a center conductor 7, an insulation layer 6, an inner shielding layer 5, an inner sheath 4, an outer shielding layer 3, and an outer sheath 2. The center conductor 7, insulation layer 6, inner shielding layer 5, inner sheath 4, outer shielding layer 3, and outer sheath 2 are arranged radially from the inside to the outside. The flexible material can be aramid fiber, polypropylene (PP), TPU elastomer, or mica tape. The insulation layer 6, inner sheath 4, outer sheath 2, and protective sleeve 1 are all made of insulating material. The inner sheath 4 is preferably made of transparent polytetrafluoroethylene to improve the shielding effect of the inner shielding layer 5 and the outer shielding layer 3. The protective sleeve 1 is preferably made of polyvinyl chloride for corrosion protection.

[0022] This embodiment achieves better shielding by setting two shielding layers on the outside of the central conductor 7 of the cable and isolating them with the inner sheath 4. It also achieves complete isolation between the inner shielding layer 5 and the outer shielding layer 3, while increasing the compressive strength. By placing the signal line 8, audio line 10, and power line 9 at three equal divisions on the outer periphery of the cable to separate them, electromagnetic influence is reduced, and the stability of the structure is increased. The flexible material can provide support and fixation while also making the entire combined coaxial cable easy to bend. Since the individual cable lines, signal line 8, audio line 10, and power line 9 are all wrapped inside the overall sheath, the cable can serve multiple functions in one cable. It can simultaneously transmit digital or analog high-frequency signals, signal transmission feedback or control, audio information, and power transmission, allowing users to experience the convenience of laying coaxial cables and the fact that they do not affect the aesthetics of the room after installation.

[0023] Preferably, the signal line 8 includes a pair of first core wires 14, two first shielding layers 13, and a first protective layer 12. The first shielding layers 13 respectively wrap around the outside of the first core wires 14 to shield the first core wires 14 and enhance the electromagnetic shielding effect. The first shielding layers 13 and the pair of first core wires 14 are both embedded in the first protective layer 12, which is an insulating material.

[0024] Preferably, the audio cable 10 includes a second core wire 17, a second shielding layer 16, and a second protective layer 15. The second core wire 17, the second shielding layer 16, and the second protective layer 15 are arranged radially in sequence, that is, the second shielding layer 16 is sleeved on the second core wire 17, and the second protective layer 15 is sleeved on the outside for protection.

[0025] Preferably, the flexible material is made of butyl rubber to achieve "three-in-one" protection, namely, sealing and waterproofing (isolating water and oxygen corrosion), strengthening electrical insulation (stabilizing signal transmission), and environmental durability (anti-aging and corrosion resistance).

[0026] Preferably, the butyl rubber is doped with 10% micro-metal particles by total mass, which enhances the structural hardness and compressive strength of the butyl rubber, while further increasing the electromagnetic shielding effect, preventing electromagnetic interference between signal line 8, cable line, audio line 10 and power line 9, and also shielding external electromagnetic waves.

[0027] Preferably, a third shielding layer 11 is fixed on the inner circumference of the protective sleeve 1 to further enhance the electromagnetic shielding effect.

[0028] Optionally, the first shielding layer 13, the second shielding layer 16, the third shielding layer 11, the inner shielding layer 5, and the outer shielding layer 3 are all made of silver-plated conductive metal wires.

[0029] Specifically, the working principle and usage process of this utility model are as follows: By setting two shielding layers on the outside of the central conductor 7 of the cable and isolating them with the inner sheath 4, a better shielding effect is achieved. It also achieves complete isolation between the inner shielding layer 5 and the outer shielding layer 3, while increasing the compressive strength. The signal line 8, audio line 10, and power line 9 are separated by placing them at three equal divisions on the outer periphery of the cable, reducing electromagnetic influence and increasing structural stability. The flexible material can play a supporting and fixing role, while also making the entire combined coaxial cable easy to bend. Since the individual cable lines, signal line 8, audio line 10, and power line 9 are all wrapped inside the overall sheath, the cable can play a multi-functional role and can simultaneously transmit digital or analog high-frequency signals, signal transmission feedback or control, audio information, and power transmission, allowing users to experience the convenience of laying coaxial cables and the fact that they do not affect the indoor aesthetics after laying.

[0030] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
