Abstract
The utility model discloses a high definition multi-media interface cable for transmitting at a high speed, which comprises a group of control wire and five groups of signal wires placed in parallel and in a same plane, the control wire and the signal wires are wrapped by a polyvinyl chloride layer as a protective jacket; the control wire comprises four first copper conductors, first insulation layers are externally coated on the four first copper conductors, and first polyester tapes are wrapped on the outer surfaces of the four first copper conductors; the signal wires comprise signal ground wires and two second copper conductors, second insulation layers are externally coated on the two second copper conductors, aluminium foil shielding layers are wrapped on the outer surfaces of the signal ground wires and the two second copper conductors, and second polyester tapes are wrapped on the outer surfaces of the aluminium foil shielding layers. Since a non-circular structure is adopted in the high definition multi-media interface cable, the problem that a segment distance of an inter wire pair changes because of stretching in the prior data cable is solved, and properties of a flexibility and a bending resistance enable the cable is not easy to deform, and the service life of the cable is prolonged.
Description
Technical field
The utility model relates to the high-definition media interface field of cables, is specifically related to a kind of high-definition media interface cable of high-speed transfer.
Background technology
HDMI is the high-definition media interface cable, mainly is a kind of digitized video/COBBAIF technology, is the tailored version digital interface that is fit to the image transmission, and it can transmit audio frequency and video-audio signal simultaneously, and the maximum data transmission speed is 5Gbps.Need not simultaneously to transmit advance capable D/A or mould/number conversion, be widely used in the inner short section of home theater, Medical Instruments and communication equipment and use the occasion that to carry out high-frequency signal transmission at signal.Traditional HDMI line all is a circular configuration, when some occasion wirings, can have defective, as: at some tiny space lining lines; The cable of circular configuration is squeezed easily, and flexural deformation causes the cable internal structure unstable; Cause distorted signals, influence transmission performance.Therefore, how to design a kind of high-definition media interface cable, become the direction that those of ordinary skills make great efforts with soft resistant to bending performance, not yielding, the physical life that can prolong cable.
Summary of the invention
The utility model purpose provides a kind of high-definition media interface cable of high-speed transfer; This high-definition media interface cable is owing to adopt non-circular structure; Solve the variation that the right pitch in available data cable interior lines takes place because of stretching effectively, thereby improved each item electrical performance indexes of cable greatly, and soft resistant to bending performance; Not yielding, prolonged the physical life of cable.
For achieving the above object; The technical scheme that the utility model adopts is: a kind of high-definition media interface cable of high-speed transfer; Comprise: parallel placement and be positioned at one group of control line and five groups of holding wires on same plane, a polyvinyl chloride layer as sheath coats said control line and holding wire;
Said control line comprises four first copper conductors, and these four first copper conductors are all outer to be covered with first insulating barrier, and first polyester belt is coated on said four first copper conductor outer surfaces;
Said holding wire comprises signal ground and two second copper conductors; All outer second insulating barrier that is covered with of these two second copper conductors; One foil shielding layer is coated on said signal ground and two second copper conductor outer surfaces, and second polyester belt is coated on said foil shielding layer outer surface.
It is following that technique scheme is further improved technical scheme:
In the such scheme, has a control ground wire in the said control line.
Because the technique scheme utilization, the utility model compared with prior art has advantage and effect:
This practical high-definition media interface cable owing to adopt non-circular structure, has solved the variation that the right pitch in available data cable interior lines takes place because of stretching effectively, thereby has improved each item electrical performance indexes of cable greatly; Secondly, owing to adopt the flat cable structure, product is pair twist direct sheath later in process of production, does not need stranding, and operation is simplified to some extent, greatly reduces production cycle and cost; Once more; Adopted soft resistant to bending PVC protective cover material by sheath outside it, conductor all adopts stranded conductor, so cable has soft resistant to bending performance; Not yielding; Prolonged the physical life of cable, and five pairs of holding wires all are parallel construction, have improved line greatly a problem of the delay inequality of signal transmission.
Description of drawings
Accompanying drawing 1 is the high-definition media interface construction of cable sketch map of the utility model high-speed transfer.
In the above accompanying drawing: 1, control line; 2, holding wire; 3, polyvinyl chloride layer; 4, first copper conductor; 5, first insulating barrier; 6, first polyester belt; 7, signal ground; 8, second copper conductor; 9, second insulating barrier; 10, foil shielding layer; 11, second polyester belt; 12, control ground wire.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Embodiment: a kind of high-definition media interface cable of high-speed transfer comprises: parallel placement and the one group of control line 1 and the five groups of holding wires 2, that are positioned at same plane coat said control line 1 and holding wire 2 as the polyvinyl chloride layer 3 of sheath;
Said control line 1 comprises four first copper conductors 4, and all be covered with first insulating barrier, 5, the first polyester belts 6 is coated on said four first copper conductor 4 outer surfaces to these four first copper conductors 4 outward;
Said holding wire 2 comprises signal ground 7 and two second copper conductors 8; All outer second insulating barrier 9 that is covered with of these two second copper conductors 8; One foil shielding layer 10 is coated on said signal ground 7 and two second copper conductor 8 outer surfaces, and second polyester belt 11 is coated on said foil shielding layer 10 outer surfaces.
Has a control ground wire 12 in the above-mentioned control line 1.
Above-mentioned conductor all adopts zinc-plated strands copper wire, and foam-Pi foaming technique is adopted in insulation, and protective cover material adopts the PVC material.
When adopting the high-definition media interface cable of above-mentioned high-speed transfer,, solved the variation that the right pitch in available data cable interior lines takes place because of stretching effectively, thereby improved each item electrical performance indexes of cable greatly owing to adopt non-circular structure; Secondly, owing to adopt the flat cable structure, product is pair twist direct sheath later in process of production, does not need stranding, and operation is simplified to some extent, greatly reduces production cycle and cost; Once more; Adopted soft resistant to bending PVC protective cover material by sheath outside it, conductor all adopts stranded conductor, so cable has soft resistant to bending performance; Not yielding; Prolonged the physical life of cable, and five pairs of holding wires all are parallel construction, have improved line greatly a problem of the delay inequality of signal transmission.
The foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection range of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection range of the utility model.
