Abstract
The utility model discloses a kind of ultrasonic wave cable, comprise signal conductor, foaming layer, the first screen, secondary shielding layer and external insulation layer; Foaming layer is established, at foaming layer peripheral hardware first screen, at the first screen peripheral hardware secondary shielding layer, at secondary shielding layer peripheral hardware external insulation layer at described signal conductor skin.The utility model ultrasonic wave cable, adopts tinned conductor, silver-plated conductor or copper to do signal conductor, and peripheral hardware first screen and secondary shielding layer, there is good signal delivery safety, reduce interference, adopt foaming layer to reduce the dielectric constant of product, loss is little, has good practicality.
Description
Technical field
The utility model belongs to field of cable technology, is specifically related to a kind of ultrasonic wave cable.
Background technology
Existing ultrasonic wave cable forms cable core by the wire of many mutual insulatings or conductor, and outside has sealing sheath, at the outer provided with shielding layer of sealing sheath and oversheath.What have is also equipped with armour etc. outside screen.This cable has certain signal transmission performance, but antijamming capability is weak, cable matter weight, and dielectric constant is large, and in exquisite high-performance place, conventional products can't meet user demand.
Utility model content
Goal of the invention: for the deficiencies in the prior art, the purpose of this utility model is to provide a kind of ultrasonic wave cable, to make it have conveying signal and lower dielectric constant preferably, meets user demand.
Technical scheme: in order to realize foregoing invention object, the technical solution adopted in the utility model is:
A kind of ultrasonic wave cable, comprises signal conductor, foaming layer, the first screen, secondary shielding layer and external insulation layer; Foaming layer is established, at foaming layer peripheral hardware first screen, at the first screen peripheral hardware secondary shielding layer, at secondary shielding layer peripheral hardware external insulation layer at described signal conductor skin.
The thickness of described secondary shielding layer is greater than the thickness of the first screen.
Described signal conductor is by two and above heart yearn is stranded forms signal delivery guidewire afterwards.
Described signal conductor is tinned conductor or silver-plated conductor or copper conductor.
Described secondary shielding layer is copper mesh braid over braid.
The first described screen is tinfoil paper layer.
The thickness proportion of the first described screen, secondary shielding layer and external insulation layer is 1:2-3:4-5.
Beneficial effect: compared with prior art, the utility model ultrasonic wave cable, tinned conductor, silver-plated conductor or copper is adopted to do signal conductor, and peripheral hardware first screen and secondary shielding layer, there is good signal delivery safety, reduce interference, skin-bubble-Pi three lager coextrusion foamed insulation is adopted to reduce the dielectric constant of product, loss is little, has good practicality, can meet the user demand in high-performance place completely.
Accompanying drawing explanation
Fig. 1 is the structural representation of ultrasonic wave cable.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, ultrasonic wave cable, comprises signal conductor 1, foaming layer 2, first screen 3 and secondary shielding layer 4; Foaming layer 2 is established, at foaming layer 2 peripheral hardware first screen 3, at the first screen 3 peripheral hardware secondary shielding layer 4, at secondary shielding layer 4 peripheral hardware external insulation layer 5 at signal conductor 1 skin.
Many barss conductor 1 stranded formation signal delivery guidewire, foaming layer 2 is enclosed with and is no less than 2 bars delivery guidewire.Signal conductor 1 is tinned conductor or silver-plated conductor or copper conductor.First screen 3 is tinfoil paper layer, and secondary shielding layer 4 is copper mesh braid over braid, and the thickness of secondary shielding layer 4 is greater than the thickness of the first screen 3.Preferably the thickness proportion of the first screen, secondary shielding layer and external insulation layer is 1:2-3:4-5.
The utility model ultrasonic wave cable, adopts tinned conductor, silver-plated conductor or copper to do signal conductor, and peripheral hardware first screen and secondary shielding layer, there is good signal delivery safety, reduce interference, adopt foaming layer to reduce the dielectric constant of product, loss is little, has good practicality.
