Background technology

Between the present widely used electronic product, particularly in order to satisfy being connected between DVD PLAYER and the TVSET, most multi-media connecting line cable (HDMI CABLE) generally adopts wire rod directly to be connected with connector on the market, the product that this processing and fabricating mode is worked it out is because the characteristic of wire rod self transmission decay is restricted the distance of product signal transmission.In order to make product be transferred to farther distance, generally all reach purpose by the diameter that strengthens heart yearn.But so, just strengthened the volume of product and the weight of self, made product become clumsy more, reduced flexibility, also increased the cost of product simultaneously, made price become more expensive, be unfavorable for the popularization and the use of product.

Fig. 1 is the cutaway view of existing multimedia digital connecting line, and this connecting line body 1 is made of a core lead 40, two core leads 20, ground wire 11 and band screen 4.The flexility of this kind multimedia digital connecting line is poor, ruptures easily when the wiring bending, thereby has reduced its useful life.

The utility model content

At the weak point that exists in the above-mentioned technology, the utility model provides a kind of flexility good, anti-bending, the high-resolution multimedia digital link that can prolong its useful life.

For achieving the above object, the utility model provides a kind of high-resolution multimedia digital link, the connecting line body comprises band screen, braid and lead, described arrangement of conductors is in the inside of described braid, described band screen is wrapped in the outer surface of described braid, also be filled with filler in braid inside, also be enclosed with sheath at the outer surface of described band screen.

Described filler is arranged between the adjacent described lead.

Described lead is divided into a core lead, two core lead and three-core conductors, and a described core lead is made of metallic conductor and the insulating barrier that is wrapped in described metallic conductor outer surface; Described two core leads are twined mutually by two holding wires and constitute, described holding wire by metallic conductor and the insulating barrier that is wrapped in described metallic conductor outer surface respectively constitute; Described three core conductors are by drawing band, ground wire, two holding wires to constitute, and described ground wire and two described holding wires are arranged on described inside of drawing band, and two described holding wires twine mutually.

Described filler is that Kev draws.

Compared with prior art, the utlity model has following advantage:

The high-resolution multimedia digital link that the utility model provides, the connecting line body comprises band screen, braid and lead, arrangement of conductors is in the inside of braid, the band screen is wrapped in the outer surface of braid, also be filled with filler in braid inside, this filler is arranged between the adjacent lead, also is enclosed with sheath at the outer surface of band screen, and this filler is that Kev draws.The utility model flexility is good, anti-bending, strengthened the load-bearing capacity of whole cable, can prolong its useful life, also have high strength, high-modulus and advantage such as high temperature resistant, acidproof, alkaline-resisting, in light weight, greatly simplified the requirement of wiring, experienced, can be used for the video of TV, LCD TV, rear-projection TV, projector, DVD record/projector and digit audio-visual display unit and the connecting line of audio signal transmission for the consumer provides the home theater of first water.

Embodiment

For clearer statement the utility model, the utility model will be further described below in conjunction with accompanying drawing.

As shown in Figure 2, the utility model provides a kind of high-resolution multimedia digital link, connecting line body 1 comprises band screen 3, braid 3 and lead, arrangement of conductors is in the inside of braid 3, band screen 4 is wrapped in the outer surface of braid 3, also be filled with filler 5 in braid 3 inside, this filler 5 is arranged between the adjacent lead, also is enclosed with sheath 2 at the outer surface of band screen 4.Wherein, filler is that Kev draws, and it is a kind of novel high-tech material that Kev draws, and has high strength, high-modulus and advantage such as high temperature resistant, acidproof, alkaline-resisting, in light weight.The intensity that Kev draws is 5～6 times of steel wire, and modulus is steel wire or glass fibre 2～3 times, and toughness is 2 times of steel wire, and weight only is about 1/5 of steel wire, does not decompose, does not melt under 560 degree temperature.Kev draws has good insulation performance performance and ageing resistace, has very long life cycle.The band screen is an aluminium foil wheat drawstring, and sheath is polyvinyl chloride, thermoplastic elastic or poly-stupid ether, is printed with manufacturer's title, the anti-temperature value of electric wire, proof voltage value on the surface of sheath.

This lead is divided into a core lead, two core lead and three-core conductors, one core lead is made of metallic conductor 31 and the insulating barrier 32 that is wrapped in metallic conductor 31 outer surfaces, insulating barrier 32 is made for polyethylene or polypropylene, and a core lead is divided into a core lead 30a, a core lead 30b, a core lead 30c, a core lead 30d and a core lead 30e.Two core leads 20 are twined mutually by two holding wires and constitute, and holding wire is made of metallic conductor 21 and the insulating barrier 22 that is wrapped in metallic conductor 21 outer surfaces respectively, and insulating barrier 22 can be polyethylene or polypropylene is made.Three core conductors are by drawing band 14, ground wire 11, two holding wires to constitute, ground wire 11 and two holding wires are arranged on the inside of drawing band 14, two holding wires twine mutually, and holding wire is made of metallic conductor 12 and the insulating barrier 13 that is wrapped in metallic conductor 12 outer surfaces respectively.Three-core conductor is divided into three-core conductor 10a, three-core conductor 10b, three-core conductor 10c, three-core conductor 10d.This insulating barrier 13 is foaming polyethylene insulating barrier, plain conductor 12 can be copper cash, tinned wird, silver-coated copper wire or gold-plated copper cash with ground wire 11, plain conductor 12 is by being that being twisted together of the regular property of multiple conducting wires made, and ground wire 11 is to be twisted together by many plain conductor systematicness to make.Draw band 14 to be aluminium foil wheat drawstring.

Because adding Kev in the connecting line body draws, make the cable heart rounding of its line wiring body, reduce the friction between single group line, pitch by cable core set forms a whole each insulating barrier and the filling of cable, strengthen ability to bear and crooking ability that whole cable bears a heavy burden, increase the service life.

More than disclosed only be several specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection range of the present utility model.
