High-performance optical fiber HDMI cable

[ technical field ]

The utility model relates to a high performance optic fibre HDMI cable.

[ background art ]

With the popularization of 4K televisions, the bandwidth required to be met by the HDMI CABLE is larger and larger, and under the condition of the same specification, compared with a copper CABLE, the HDMI AOC product has the advantages of being longer, thinner, softer, better in signal quality, free of radiation and free of electromagnetic interference, and therefore is widely adopted. However, HDMI pure optical fiber products in the market are not usable or have poor contact due to the fact that the fiber core vulnerability is difficult to realize long-distance tensile property, and the HDMI pure optical fiber products are easily affected by problems such as external force damage, violent pulling, water seepage and the like when applied to scenes such as outdoor stage renting and the like.

[ detailed description of the invention ]

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that all the directional indicators (such as upper, lower, left, right, front, rear \8230;) in the embodiments of the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the attached drawings), and if the specific posture is changed, the directional indicator is changed accordingly. Furthermore, the descriptions of "preferred," "less preferred," etc. in this application are for descriptive purposes only and are not to be construed as indicating or implying relative importance or to implicitly indicate the number of technical features indicated. Thus, a feature defined as "preferred" or "less preferred" may explicitly or implicitly include at least one such feature.

The first embodiment is as follows: as shown in fig. 1-2, a high-performance optical fiber HDMI cable comprises four optical fiber cores 1, wherein a fiber core insulating protective sleeve 2, a water-blocking protective sleeve layer 3 and an insulating outer sheath layer 4 are sequentially sleeved outside the four optical fiber cores 1, an optical fiber grease layer 5 is arranged between the optical fiber cores 1 and the fiber core insulating protective sleeve 2, and at least one tensile phosphated steel wire 6 is arranged on the insulating outer sheath layer 4 along the length direction.

The semi-solid optical fiber grease layer 5 is arranged in the fiber core insulating protective sleeve 2, so that a glass fiber core coating layer can be protected, and scratching caused during wire drawing is avoided; the fiber core insulating protective sleeve 2 is used for performing an insulating protection function on the fiber cores 1 of the four optical fibers; the water-blocking sheath layer 3 improves the waterproofness of the optical fiber HDMI cable and prevents water from entering the optical fiber core; the insulating outer layer 4 is used for an external insulating protection function; set up tensile bonderizing steel wire 6 in insulating tegument 4, improve the tensile ability of optic fibre HDMI cable, when pulling optic fibre HDMI cable, tensile bonderizing steel wire 6 bears main pulling force, prevents external force effectively and breaks the optic fibre core.

The fiber core insulating protective sleeve 2 is a fiber core polypropylene protective sleeve and has good insulating and fiber core protecting functions; the water-blocking sheath layer 3 is a polyolefin sheath layer and has good waterproofness; the insulating outer tegument 4 is a PVC outer tegument, is wear-resistant and has good insulation and flexibility; tensile phosphating steel wires 6 are two and are symmetrically arranged in the insulating outer tegument 4, so that the tensile capacity of the optical fiber HDMI cable is enhanced, and an optical fiber core is better protected.

Example two: as shown in fig. 3-4, the difference from the embodiment is that an annular steel armor layer 7 is disposed between the core insulation jacket 2 and the water-blocking jacket layer 3, and the annular steel armor layer 7 spirally surrounds the outside of the core insulation jacket 2. Can improve the anti ability of trampling and weighing of optic fibre HDMI cable through setting up annular steel first layer 7, solve because external force tramples and heavily press and cause the damage.

The above is only the preferred embodiment of the present invention, not limiting the patent scope of the present invention, all of which are under the concept of the present invention, the equivalent structure transformation made by the contents of the specification and the drawings is utilized, or the direct or indirect application is included in other related technical fields in the patent protection scope of the present invention.
