Description

Optical fiber V R audio frequency and video lines

Technical field

It the utility model is related to data transfer wire rod field, more particularly to a kind of optical fiber V R audio frequency and video lines.

Background technology

Traditional VR cable architectures, as shown in figure 1, four pairs of HW High Ways refer to the HDMI signal wires 1 of four groups of transmission HDMI signals, For four pairs of HW High Ways using copper cash or alloy conductor as transmission signal vector, isolation material is mostly Teflon material, outside wire rod Footpath is larger, and feel is partially hard, weight weight, and expensive.When the cable and VR coordinative composition of equipments using when wire rod lay particular stress on and cause reality It is very inconvenient during operation, and use for a long time is larger for personal physical demands.

Traditional VR wire rods use length because being influenceed (mainly based on 34AWG or 36AWG) by wire specification and high frequency characteristics It is limited within 3M, for use length of the display device of 4K resolutions more than more than 3M, existing VR wire specifications can not Meet, otherwise need to increase conductor specification or the active component of increase.

Traditional VR wire rod structures are complicated, and production procedure is more.The wherein HDMI signals of HDMI fractional transmissions audio-video signal Line 1 needs 4 pairs of twisted pair wires, first twists copper, then gives as security cored wire, adds ground wire pair twist, coats aluminium foil and wheat drawstring, and other electric wires 1 and electricity Sub-line 2 twists together, then adds aluminium foil braid shielded, gives as security outer quilt, procedure for processing is more, and flow is cumbersome, causes high frequency stability Bad control, fraction defective are higher.It is simultaneously larger by periphery electromagnetic interference influence.

Utility model content

The purpose of this utility model is to provide a kind of optical fiber V R audio frequency and video lines, and wire rod external diameter is small, in light weight.

To use following technical scheme up to this purpose, the utility model：

A kind of optical fiber V R audio frequency and video lines, including sheath and the medium line group in the sheath, the medium line group Including fiber-optic signal line group, the first electric wire group, the second electric wire group, ground wire and some anti-elater, the fiber-optic signal line group, The first electric wire group, the second electric wire group, the ground wire and the twisted composition medium line of some anti-elater Group, effectively strengthen the tensile resistance of sliver, the fiber-optic signal line group is used to transmit HDMI signals, and the second electric wire group passes Defeated usb signal.The cross section of the fiber-optic signal line group is circle, and some anti-elater contact with the fiber-optic signal line group Set.

Specifically, fiber-optic signal line group replaces traditional using copper cash or alloy conductor as transmission signal vector, greatly The overall weight and wire rod external diameter of wire rod, the wire rod of same length are reduced, overall weight can mitigate more than 50 percent.The One electric wire group and the second electric wire group can be used as power line or control line, can also realize other functions.

Specifically, optical fiber substitutes classical signal transmission medium so that half can be reduced in cored wire quantity, while external diameter also may be used Accomplish 3.2 millimeters, it is smaller than traditional VR wire rods by 30 percent.Because the proportion of copper conductor is 8.89 grams/cm3, the ratio of optical fiber Weigh about as 1.0 grams/cm3, so the optical fiber V R audio frequency and video line overall weights that wire rod this programme of same length provides can mitigate More than 50 percent.Simultaneously because the pad value of fiber-optic signal is smaller, actual use can reach hundreds of meters.

In use, photoelectricity module is set to be changed at the both ends of optical fiber V R audio frequency and video lines, so in transmission without electricity Magnetic radiation, and strong antijamming capability.

Preferably, the sheath is TPE (Thermoplastic Elastomer, thermoplastic elastomer (TPE)) material, it is described Ground wire is tin plating copper material, and the specification of the ground wire is 28AWG.

It is preferably, described middle by for FEP, (Fluorinated ethylene propylene, fluoroethylene-propylene are copolymerized Thing) material.

Preferably, the specification of the first electric wire group is 7 core 34AWG.AWG (American wire gauge, it is beautiful State's line gauge), the numerical value (such as 28AWG, 30AWG) before AWG represents the size of conductor cross sectional area after the completion of wire, and numerical value is bigger, Sectional area is smaller, and conductor diameter is smaller.Otherwise numerical value is smaller, and sectional area is bigger, and conductor diameter is bigger.

Preferably, the specification of the second electric wire group is two core 30AWG and two core 24AWG.

Preferably, cotton paper clad is provided between the medium line group and the sheath.

The beneficial effects of the utility model：Signal is used as using copper cash or alloy conductor instead of traditional with fiber-optic signal line group Transmission medium, greatly reduces the overall weight and wire rod external diameter of wire rod, the wire rod of same length, and overall weight can mitigate hundred / five more than ten.Optical fiber V R audio frequency and video cable architectures are simple, and work flow is few, and technique is simple, and wire properties are easily controlled, no Yield is small, radiationless, strong antijamming capability.
