Description

Technical Field

[0001] This utility model relates to the field of HDMI data cable technology, specifically a small HDMI ultra-high-definition data cable. Background Technology

[0002] A compact HDMI cable is an HDMI cable designed specifically for small devices, providing high-definition audio and video transmission. These cables typically feature a thinner design for easy portability and use while ensuring signal quality. They are suitable for data transmission between various devices and are particularly well-suited for applications requiring high-quality audio and video output.

[0003] In existing technologies, improving the quality of ultra-high-definition data cables has always been a research direction in this field. As mentioned in the Chinese patent application CN202120752216.9, which describes a high-toughness HDMI high-definition data cable: "An HDMI cable body and HDMI connectors respectively disposed at both ends of the HDMI cable body. The HDMI cable body includes nineteen conductors. The HDMI cable body includes, from the inside out, a receiving space, a first shielding layer, a metal braided shielding mesh layer, a PVC outer sheath layer, and a nylon braided mesh layer. Each conductor is disposed in the receiving space, and each conductor is covered with an insulation layer. This utility model has high toughness, a long service life, and is well-suited for daily life."

[0004] This technology improves the toughness of data cables by modifying their structure, thereby extending their service life. However, this method only improves the internal structure of the data cable, while the surface of the data cable often faces more severe conditions. Since the outside of the data cable is exposed to the outside for a long time, it usually has to deal with dust, moisture, wear and tear in the environment. Therefore, how to improve the protection of the outer surface of small HDMI ultra-high-definition data cables and extend their service life has become an urgent problem to be solved in this field. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a small HDMI ultra-high-definition data cable, comprising a data cable body and a data cable connector. The data cable body includes a rubber protective layer, a shielding layer is disposed inside the rubber protective layer, an armor layer is disposed inside the shielding layer, and an insulation layer is disposed inside the armor layer. Multiple wire cores are disposed inside the insulation layer, and an insulation layer two is disposed outside each wire core. The surface of the rubber protective layer is coated with a film layer, which is composed of three layers: a polypropylene layer, an aluminum oxide layer, and a titanium dioxide layer.

[0007] As a further embodiment of this utility model: the polypropylene layer is plated on the surface of the rubber protective layer, the alumina layer is plated on the surface of the polypropylene layer, and the titanium dioxide layer is plated on the surface of the alumina layer.

[0008] As a further embodiment of this utility model: rubber columns are fixed in a ring at equal intervals inside the rubber protective layer, and the interior of the rubber columns is a hollow structure.

[0009] As a further embodiment of this utility model: the interior of the first insulating layer is fixed with two sets of rubber pillars in a ring shape, each set including five rubber pillars, and each rubber pillar is close to the corresponding wire core, and the interior of the rubber pillar is hollow.

[0010] As a further embodiment of this utility model: the rubber protective layer is made of polyvinyl chloride plastic, and both the first insulating layer and the second insulating layer are made of styrene-butadiene rubber.

[0011] As a further embodiment of this utility model: the shielding layer is composed of a woven tin-plated copper mesh, and the armor layer is composed of a woven steel strip mesh.

[0012] As a further embodiment of this utility model: the data cable connector includes two connectors, and the two data cable connectors are respectively connected to both ends of the data cable body.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] I. In this application, a coating layer composed of a polypropylene layer, an aluminum oxide layer, and a titanium dioxide layer is designed on the surface of the data cable body. The hydrophobic properties of polypropylene provide better waterproof and dustproof functions, while the high hardness and wear resistance of aluminum oxide provide better mechanical protection, making it more wear-resistant. Titanium dioxide, a common photocatalytic material, has good self-cleaning properties, decomposing organic pollutants and keeping the surface of the data cable clean. In summary, by designing a coating layer on the data cable body, the waterproof, dustproof, wear-resistant, and self-cleaning effects of the cable can be effectively improved, thereby extending the lifespan of the small HDMI ultra-high-definition data cable.

[0015] Second, in this application, by designing rubber pillar one and rubber pillar two in the rubber protective layer and the insulation layer one respectively, and by making the interior of rubber pillar one and rubber pillar two hollow, the bending force can be buffered by rubber pillar one and rubber pillar two when the entire data cable body is bent, thereby buffering the pressure on the internal wire core, reducing the possibility of damage to the wire core when bending, and further improving the service life of the small HDMI ultra-high-definition data cable.

[0022] Please see Figure 1-3 A small HDMI ultra-high-definition data cable includes a data cable body 1 and data cable connectors 101. Two data cable connectors 101 are provided, each connected to one end of the data cable body 1. The data cable body 1 includes a rubber protective layer 2, a shielding layer 3 inside the rubber protective layer 2, an armor layer 4 inside the shielding layer 3, and an insulation layer 5 inside the armor layer 4. Multiple wire cores 6 are disposed inside the insulation layer 5, and each wire core 6 is surrounded by an insulation layer 7. A coating layer 8 is deposited on the surface of the rubber protective layer 2. The coating layer 8 consists of three layers: a polypropylene layer 801, an aluminum oxide layer 802, and a titanium dioxide layer 803. The polypropylene layer 801 is deposited on the surface of the rubber protective layer 2, the aluminum oxide layer 802 is deposited on the surface of the polypropylene layer 801, and the titanium dioxide layer 803 is deposited on the surface of the aluminum oxide layer 802.

[0023] Specifically, the polypropylene layer 801 provides good waterproof and dustproof performance on the surface of the data cable body 1, the aluminum oxide layer 802 provides good wear resistance for the data cable body 1, the titanium dioxide layer 803 provides good self-cleaning performance for the data cable body 1, and the titanium dioxide can also serve as an ultraviolet (UV) blocking layer to reduce the impact of ultraviolet rays on the internal materials.

The rubber pillars 501 have a hollow structure inside.

[0025] Specifically, the hollow rubber pillar 201 can buffer the bending force for the first time after the data cable body 1 is bent, thereby improving the bending resistance of the entire data cable body 1. The hollow rubber pillar 501 can buffer the bending force of each wire core 6 near each wire core 6, thereby reducing the pressure on the wire core 6.

[0026] Please see Figure 1-2 In this embodiment, the rubber protective layer 2 is made of polyvinyl chloride plastic, and the insulating layer 5 and the insulating layer 7 are both made of styrene-butadiene rubber.

[0027] Specifically, the rubber protective layer 2 made of polyvinyl chloride plastic can improve the corrosion resistance of the entire data cable body 1, while the insulation layer 5 and insulation layer 7 made of styrene-butadiene rubber meet the insulation requirements of the wire core 6 and the insulation requirements of the entire data cable body 1.

[0028] Please see Figure 1-2 In this embodiment, the shielding layer 3 is made of a woven tin-plated copper mesh, and the armor layer 4 is made of a woven steel strip mesh.

[0029] Specifically, the shielding layer 3, composed of tin-plated copper mesh, can improve the anti-shielding performance of the data cable body 1, while the armor layer 4, composed of steel strip mesh, can provide additional mechanical protection and improve the tensile and compressive strength of the data cable body 1.
