Abstract

The utility model discloses a composite eight-core coaxial-wire differential signal transmission HDMI (High Definition Multimedia Interface) cable. The composite eight-core coaxial-wire differential signal transmission HDMI cable comprises eight coaxial wires, an independent electronic wire and a twisting electronic wire of which the outside are sequentially wrapped with aluminum foil, wound by soft copper wires and sleeved by an extrusion plastic sleeve. The coaxial wires adopt a plurality of strands of copper wires as a conductor; a Teflon insulating layer is outside the strands of copper wires; a copper wire shielding layer is outside the Teflon insulating layer; hot-melt Dacron resin belts are wound and wrapped outside the copper wire shielding layer, and the hot-melt surface is towards inside to be used as the sleeve layer of the coaxial wires, and paint spraying rings are in the sleeve layer to mark serial numbers. Because the single coaxial signal wire is independently shielded and soft, and has bending resistance and repeated use, the performance of the composite eight-core coaxial-wire differential signal transmission HDMI cable cannot be lowered. If the coaxial wire of which the wire specification is 36AWG is used for HDMI transmission, the transmission distance can be 5.0 meters; and if the coaxial wire of which the wire specification is 40AWG is used for HDMI transmission, the transmission distance can be 3.0 meters.

Description

A kind of compound 8 core coaxial line differential signal transmission HDMI cables

Technical field

The utility model relates to a kind of electric wire, and particularly coaxial line differential signal transmission HDMI HDMI cable especially adopts compound 8 core coaxial line differential signal transmission HDMI signal cables.

Background technology

In the prior art; Automobile, aviation,, antistatic laboratory, operating room etc. require the application scenario of transmission high definition audio-video signal; When traditional HDMI (HDMI) line uses; Because of its cable adopts insulation heart yearn pair twist, uses as a pair of holding wire with foil shielding layer after adding ground wire, owing to the restriction of structure and process aspect; Its transmission range often receives the influence of conductor sizes and holding wire insulating material, only can transmit 1.5 meters like the HDMI transmission range of wire gauge 36AWG; The HDMI transmission range of wire gauge 40AWG only can be transmitted 0.8 meter, therefore on length, uses, and receives very big restriction.

And; Traditional pair twist structure; Slightly inadequate on antijamming capability, and for require the stronger occasion of antijamming capability as: aviation, automobile, antistatic laboratory, operating room etc. require transmission high definition audio-video signal, and possible these common pair twist holding wires are just powerless.

And,, mobile digital require cable soft, light in using, anti-bending, and traditional HDMI cable can reduce its transmission performance in repeatedly bending and carrying.

The utility model content

The purpose of the utility model is for the transmission range that solves prolongation HDMI and the problem of transmission quality: can use 5.0 meters such as wire gauge 36AWG; Wire gauge 40AWG can use 3.0 meters, and how with HDMI be used for the stronger occasion of requirement antijamming capability as: aviation, automobile, antistatic laboratory, operating room etc. require the occasion of transmission high definition audio-video signal.

The utility model is through adopting following technical scheme to realize:

Manufacture and design compound 8 core coaxial line differential signal transmission HDMI cables, comprising:

8 coaxial lines, independent electronic line, stranded electronics line wrap up aluminium foil successively, twine annealed copper wire and extrusion plastic sheath in their outside.

What described coaxial line adopted is that the multiply copper cash is made conductor; Be insulating layer of Teflon outside the multiply copper cash; Insulating layer of Teflon outside is the copper wire screen, and the wrapped heat in copper wire screen outside is melted the polyester resin band, heat melt face in; Be used as the restrictive coating of coaxial line, restrictive coating has paint spray ring to identify sequence number.

Described multiply copper cash adopts the copper cash of 7 * 0.05mm in the 36AWG wire gauge.

Described multiply copper cash adopts the copper cash of 7 * 0.03mm in the 40AWG wire gauge.

Compared with prior art, the utility model is because the monomer coaxial signal line all is an individual screen, and wire rod is soft, and anti-bending, repeatedly uses repeatedly, and its performance can obviously not reduce.

The coaxial line of wire gauge 36AWG is done the HDMI transmission, and its transmission range can reach 5.0 meters.

The coaxial line of wire gauge 40AWG is done the HDMI transmission, and its transmission range can reach 3.0 meters.

Embodiment

Below in conjunction with most preferred embodiment shown in the drawings the utility model is done further detailed description:

Manufacture and design a kind of compound 8 core coaxial line differential signal transmission HDMI cables such as Fig. 1～shown in Figure 3.

The compound 8 core coaxial line differential signal transmission HDMI cable preferred embodiments of the utility model include:

8 coaxial lines 1, independent electronic line 2, stranded electronics line 3 wrap up aluminium foil 4 successively, twine annealed copper wire 5 and extrusion plastic sheath 6 in their outside.

What described coaxial line 1 adopted is that multiply copper cash 11 is made conductor; It outside the multiply copper cash 11 insulating layer of Teflon 12; Insulating layer of Teflon 12 outsides are copper wire screens 13, and the wrapped heat in copper wire screen 13 outsides is melted the polyester resin band, heat melt face in; Be used as the restrictive coating 14 of coaxial line, restrictive coating 14 has paint spray ring to identify sequence number.
