Abstract
The utility model relates to a railway digital signal transmission cable. The railway digital signal transmission cable has a simple structure, can effectively prevent mutual interference among signals of wires and external interference, and is high-temperature resistant. The railway digital signal transmission cable comprises a copper core wire, and an inner insulating layer, a foaming layer and an outer insulating layer are arranged outside the copper core wire; an inner shielding layer is also arranged between the outer side of the copper core wire and the inner insulating layer; an outer shielding layer is arranged between the foaming layer and the outer insulating layer; and a high-temperature resistant layer is also arranged outside the outer insulating layer.
Description
Technical field
The utility model relates to a kind of railway digital signal transmission cable.
Background technology
Chinese patent 002689669 has provided the digital signal cable that a kind of railway is used.But this cable only is to have adopted foaming technique to make insulating barrier, but and the signal interference problem between unresolved lead, and external disturbance problem; This cable does not possess the ability of withstand high temperatures yet simultaneously.
The utility model content
The purpose of this utility model provides a kind of simple in structure exactly for addressing the above problem, and can effectively avoid mutual interference of signal phase and external disturbance between lead, and can withstand high temperatures the railway digital signal transmission cable.
For achieving the above object, the utility model adopts following technical scheme:
A kind of railway digital signal transmission cable, it comprises copper core, is inner insulating layer, foaming layer and external insulation layer in the outside of copper core, also is provided with internal shield between described copper core outside and inner insulating layer; Between foaming layer and external insulation layer, be provided with outer shielding layer, also be provided with high-temperature-resistant layer in the outside of external insulation layer.
The utility model has increased by two screens on the basis of existing technology, has effectively avoided copper core to the interference of outside and the interference of outer bound pair copper core.
The beneficial effects of the utility model are: simple in structure, antijamming capability is strong.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein, 1 copper core, 2 inner insulating layers, 3 foaming layers, 4 external insulation layers, 5 internal shields, 6 outer shielding layers, 7 high-temperature-resistant layers.
Embodiment
