Abstract
The utility model relates to an HDMI high-frequency coil comprising a signal line pair, a power line and a covering coated outside the signal line pair and the power line, wherein the signal line pair consists of two signal lines, a grounding line and a metal layer coating the signal lines and the grounding line; and aluminium foil layers are also arranged among the signal line pair, the power line and the covering. As the aluminium foil layers are also arranged among the signal line pair, the power line and the covering, without a woven structure, the line twisting procedure is avoided, copper for weaving does not exist, and the covering glue is saved. By testing, the signal transmission after changing is enhanced on the original basis, and the cost is reduced.
Description
Technical field
The utility model relates to a kind of HDMI high-frequency line.
Background technology
HDMI (High Definition Multimedia Interface; be HDMI (High Definition Multimedia Interface)) can transmit high-qualityly the HD video and the multichannel audio data of uncompressed; the maximum data transmission speed is 5Gbps; need not simultaneously to transmit advance capable D/A or mould/number conversion at signal; the video-audio signal that can guarantee first water transmits, and therefore is widely used in modern audio-visual devices such as digital TV in high resolution.
Along with the arrival of digital Age, HDMI is as a kind of standard interface of high definition, and the signal of transmission of digital audio frequency and lossless video simultaneously has the picture and the sound quality of high definition, is extensively relied in the family.Existing HDMI high-frequency line, as shown in Figure 1, generally comprise four holding wires to 100, complex root power line 200 and be wrapped in successively this holding wire to 100, outer aluminium foil layer 300, braid 400 and the insulation of power line 200 be outer by 500; The #30 conductor is 7/0.10AS among existing UL20276 (#30/1P+A) the * 4P+#30/1P+#30/4C+#28/1C+AB, is woven to 64/0.10TD OD: Φ 6.0mm.Yet, since the HDMI high-frequency line to request signal transmission than higher, existing HDMI high-frequency line is subjected to extraneous factor to influence jitter, and higher aspect cost.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of can reducing cost, the HDMI high-frequency line of signal stabilization.The utility model is achieved through the following technical solutions:
A kind of HDMI high-frequency line of the present utility model comprises that holding wire is to, power line and be wrapped in this holding wire to, the outer outer quilt of power line; Wherein, described holding wire is to comprising two holding wires, an earth connection and the metal level that wraps up this holding wire, earth connection, described holding wire to, power line and outward by between also be provided with aluminium foil layer.
As preferably, described holding wire comprises conductor, and is coated on the outer insulating barrier of conductor.
As preferably, described conductor is 1/0.254AD.
As preferably, described metal level is an aluminum foil material.
HDMI high-frequency line of the present utility model and since described holding wire to, power line and outward by between also be provided with aluminium foil layer, no braiding structure; Avoided the twisted wire operation like this, do not had braiding copper, saved outer by sizing material.Through test, signal after changing is transmitted on the original basis and has strengthened, and has reduced cost.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following preferred embodiment and accompanying drawing.
Fig. 1 is the front view of prior art HDMI high-frequency line;
Fig. 2 is the front view of the utility model HDMI high-frequency line.
Embodiment
As shown in Figure 2, a kind of HDMI high-frequency line of the present utility model, comprise holding wire to 1, power line 2 and be wrapped in this holding wire to 1, outer outer of power line 2 by 3; Wherein, described holding wire comprises two holding wires 10, an earth connection 11 and the metal level 12 that wraps up this holding wire 10, earth connection 11 to 1, described holding wire to 1, power line 2 and between 3, also be provided with aluminium foil layer 4, no braiding structure outward; Avoided the twisted wire operation like this, do not had braiding copper, saved outer by sizing material.Through test, signal after changing is transmitted on the original basis and has strengthened, and has reduced cost.In the present embodiment, described metal level 12 is an aluminum foil material.
Wherein, described holding wire 10 comprises conductor 13, and is coated on the insulating barrier 14 outside the conductor 13.#30 conductor 13 is 1/0.254AD in the present embodiment, no braiding structure, OD:5.5mm.Avoided the twisted wire operation like this, do not had braiding copper, saved outer by sizing material.
HDMI high-frequency line of the present utility model and since described holding wire to, power line and outward by between also be provided with aluminium foil layer, no braiding structure; Avoided the twisted wire operation like this, do not had braiding copper, saved outer by sizing material.Through test, signal after changing is transmitted on the original basis and has strengthened, and has reduced cost.
The foregoing description; it is an example of the present utility model; be not to be used for limiting enforcement of the present utility model and interest field, all or technical schemes of being equal to identical with the described content of the utility model claim all should be included in the utility model protection range.
