Abstract
The invention discloses a method for coating a shielding cable shielding layer, comprising steps as follows: placing a core wire of a shielding cable and a metal thin strip for coating the core wire in a leading-in eye film, so that the metal thin strip, together with the core wire, is coated on the core wire after passing through a hole of the leading-in eye film by the introduction of a horn mouth of the leading-in eye film to form a shielding layer; then passing the core wire coated with the shielding layer through at least one pressed eye film so that the shielding layer is tightly coated on the core wire. The shielding cable produced by the coating method has linear openings of the shielding layer, and the openings of the shielding layer of the shielding cables face towards different directions when used as high-frequency signal lines, thereby signal cross interference on the shielding cables is greatly reduced and normal operation of relevant devices without influence is ensured. The coating method provided by the invention is especially suitable for coating seven types of cable shielding layers.
Description
Technical field
The present invention relates in the shielding cable production process, be coated on method for coating on the heart yearn that shields cable as screen with metal sheet band.
Background technology
As shown in Figure 1, the method for coating of the present shielding cable shielding layer of using always, the aluminium foil 3 that the steps include: to be used to coat the heart yearn 2 of shielding cable is wrapped in heart yearn 2, forms screen, and the heart yearn 2 that will be wound with aluminium foil 3 then packs tightly aluminium foil 3 on heart yearn 2 through compressing a mould 1 together.The shielding cable of producing by above-mentioned method for coating, as the high-frequency signal line time, the direction of healing up owing to the aluminium foil 3 as screen is divergent shape, generally, aluminium foil 3 heals up and can not accomplish that tight silk is seamless, like this with regard to the many high-frequency signal lines that put together, exist serious string to scratch phenomenon between the signal on the signal that leaks from the slit that heals up of its screen on every high-frequency signal line and all the other the high-frequency signal lines, influenced the operate as normal of relevant device.
Summary of the invention
Technical problem to be solved by this invention is: a kind of method for coating that makes the linearly shielding cable shielding layer of healing up of screen is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the method for coating of shielding cable shielding layer, the steps include: the heart yearn of shielding cable is put into an importing eye mould together with the metal sheet band that is used for cladding core wire, make that metal sheet band is coated on the heart yearn pass the nib that imports the eye mould synchronously with heart yearn under the bell-mouthed guiding that imports the eye mould after, the formation screen, the heart yearn that will be coated with screen then packs tightly on heart yearn screen through compressing a mould at least together.
The described heart yearn that is coated with screen through the front and back twice compress a mould compress promptly a mould and after compress a mould, screen is packed tightly on heart yearn.
The invention has the beneficial effects as follows: the shielding cable that adopts method for coating of the present invention to produce, healing up of its screen is linearly, when the high-frequency signal line, can many shields the healing up towards to a plurality of different directions of screen of cables.Like this, the signal that leaks from the slit of screen of many shielding cables has reduced the many strings that shield the signal on the cable greatly and has scratched also just towards to a plurality of different directions, has guaranteed that the relevant device operate as normal is unaffected.

Among the figure: 1, import an eye mould, 11, catch, 2, a preceding mould that compresses, 3, after compress a mould, 4, heart yearn, 5, aluminium foil.
Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As shown in Figure 2, the method for coating of shielding cable shielding layer of the present invention, the aluminium foil 5 that the steps include: the heart yearn 4 of shielding cable and be used to coat this heart yearn 4 is put into together and is imported an eye mould 1, wherein: heart yearn 4 enters the nib that imports eye mould 1 from the outside of the catch 11 of importing eye mould 1, aluminium foil 5 enters the nib that imports eye mould 1 from the inboard of the catch 11 of importing eye mould 1, make aluminium foil 5 just under the bell-mouthed guiding that imports eye mould 1, after passing the nib that imports eye mould 1 synchronously, heart yearn 4 is coated on the heart yearn 4, screen---healing up of screen is healing up in line of aluminium foil 5 in formation, then, with the heart yearn 4 that is coated with screen successively through before compress a mould 2 compressing in advance and after compress after the compressing an of mould 3---the preceding nib that compresses a mould 2 than after to compress the nib of a mould 3 big slightly, feasible aluminium foil 5 as screen tightly is coated on the heart yearn 4, forms the shielding cable.
Claims (2)
1. the method for coating of shielding cable shielding layer, the steps include: the heart yearn of shielding cable is put into an importing eye mould together with the metal sheet band that is used for cladding core wire, make that metal sheet band is coated on the heart yearn pass the nib that imports the eye mould synchronously with heart yearn under the bell-mouthed guiding that imports the eye mould after, the formation screen, the heart yearn that will be coated with screen then packs tightly on heart yearn screen through compressing a mould at least together.
2. the method for coating of shielding cable shielding layer as claimed in claim 1 is characterized in that: the described heart yearn that is coated with screen through the front and back twice compress a mould compress promptly a mould and after compress a mould, screen is packed tightly on heart yearn.
