Abstract
The utility model discloses a high speed cable, comprising at least a pair of signal wires, a grounding wire and a protective leather wrapping the signal wires and the grounding wire. The grounding wire is located between the signal wires and the protective leather, the signal wires comprise core wires used for transmitting a signal, an insulating leather wrapping the core wires and a braided layer wrapping the insulating leather. An insulating layer and the core wires are wrapped by the braided layer separately to guarantee that capacitances are not generated between the core wires when the signal is transmitted, so that the signal transmission is more stable.
Description
Technical field
The relevant a kind of cable that is used for transmit high-speed signals of the utility model.
Background technology
Along with the continuous development of electronic technology, the cable that transmits as signal has obtained very big development.In the transmission course of signal, cable receives outside electromagnetic interference easily and influences the transmission of signal.Usually, can be employed in the structure that increases some shield electromagnetic interference on the cable, be used to reduce the influence of electromagnetic interference the signal transmission.
At present, the braid and of insulated hull coated the external insulation skin of braid in existing a kind of cable comprised some heart yearns, the interior insulated hull, of cladding core wire coats respectively.Heart yearn is used for the transmission of signal or power supply, and braid has the aluminum metal of conduction, has the extraneous electromagnetic interference function of shielding.But because in signals transmission, have only interior insulated hull that it is separated between some heart yearns, can generation electric capacity between heart yearn and the heart yearn, and this electric capacity brings bigger influence to the transmission of signal.Therefore, cable itself can produce the transmission adverse factors, can not guarantee the stability of signal transmission.
Therefore, need provide a kind of new technical scheme to overcome said problem.
The utility model content
The purpose of the utility model is the deficiency that exists to prior art, and a kind of high speed cable of guaranteeing stable signal transmission property is provided.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of high speed cable comprises at least one pair of holding wire, an earth connection and coats the protection skin of said holding wire and said earth connection; Said earth connection is between said holding wire and said protection skin, and said holding wire comprises the heart yearn that is used for transmission signals, coat the insulated hull of said heart yearn and coat the braid of said insulated hull.
Compared with prior art, the utility model high speed cable has following beneficial functional: braid is coated insulation layer and heart yearn respectively, when guaranteeing the signal transmission, does not produce electric capacity between the heart yearn, makes the signal transmission have more stability.
Description of drawings
Fig. 1 is the plan view of the utility model high speed cable.
Fig. 2 is the cutaway view of high speed cable A-A direction along the line shown in Figure 1.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the utility model; Should understand these embodiment only be used to the utility model is described and be not used in the restriction the utility model scope; After having read the utility model, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the utility model.
See also Fig. 1 to shown in Figure 2, the utility model high speed cable 1 comprises the protection skin 4 of a pair of holding wire 2, the earth connection between holding wire 23 and parcel holding wire 2 and earth connection 3.The arrangement that two signal line 2 are parallel, earth connection 3 are between holding wire 2, and holding wire 2 is parallel to each other with earth connection 3.Earth connection 2 is between holding wire 2 and protection skin 4.Protection skin 4 firmly is coated togather holding wire 2 and earth connection 3 and is not damaged under external force with good protection high speed cable 1.
Every signal line 2 comprises the insulated hull 22 and the braid 23 of heart yearn 21, cladding core wire 21.Braid 23 can be processed for the aluminum material of conduction.Heart yearn 21 is used for transmission signals, and insulated hull 22 separates heart yearn 21 and braid 23, and braid 23 contacts with earth connection 3.Braid 23 coated insulation skins 22 are guaranteed when signal transmits, not receive the interference of external electromagnetic signal, and avoid the signal of high speed cable 1 can not reveal.Simultaneously, can not produce electric capacity between the heart yearn 21, thereby guarantee the signal transmission more stable.
