Description
Technical field
Field of cable technology is the utility model is related to, specifically, the utility model is more particularly to a kind of strong shielded cable
Technical field.
Background technology
Shielded cable is the cable of the anti-outside electromagnetic interference ability formed in the additional screen layer mode of transmission cable.It is this
The screen layer of cable mostly using webbed metal wire is woven or using metallic film, have single screen cover with multi-shielding it is a variety of not
Same mode.Single screen, which is covered, refers to single gauze screen or screened film, wherein one or more wire can be wrapped up.Multi-shielding mode is more
Individual gauze screen, screened film are co-located in a cable.Some is used for the electromagnetic interference completely cut off between wire, has plenty of to strengthen
Shield effectiveness and the double layer screen used.The mechanism of action of shielding is to be allowed to shielding layer grounding to completely cut off the external sensing to wire
Interference voltage.
But with the fast development of electronics industry, to the shielding requirements more and more higher of signal wire, peripheral hardware gauze screen at present
Although cable have certain shielding action to weak jamming around, for high-intensity magnetic field highfield disturb it is still very weak, especially exist
In the military use very high to shielding requirements, even more far from have the function that shield outer signals interference.
The content of the invention
For the technological deficiency of prior art shielded cable shielding action difference, the utility model provides a kind of strong shielding electricity
Cable, on the basis of original shielding stratum reticulare, adds ferrite layer, suppresses the logical of high-frequency interferencing signal using ferrite powder
Cross, and cost is cheap, prevents the interference in outer bound pair signals transmission and steals, drastically increases the shielding of shielding line
Effect.
The technical scheme that the utility model is provided is as follows：
The utility model provides a kind of strong shielded cable, including conduction copper core, ferrite layer, foaming PE layers and fire-retardant outer
Set, conduction copper core are surrounded by cable core filler, and cable core filler is externally provided with metallic shield net, and metallic shield net is wrapped with hair
PE layers are steeped, foaming PE layers are externally provided with ferrite layer, and ferrite layer is wrapped with fire-retardant overcoat.
In the utility model, ferrite layer is that ferrite powder coats dry formed in PVA glue after even suspension
Ferrite PVA mixture layers.
In the utility model, conduction copper core has more than two.
In the utility model, insulating barrier is surrounded by outside conduction copper core.
In the utility model, the conduction copper core for being surrounded by insulating barrier multigroup twists together.
In the utility model, ferrite layer, foaming PE layers and fire-retardant overcoat are coaxial configuration.

The beneficial effects of the utility model：
A kind of strong shielded cable described in the utility model, is electromagnetically shielded using the ferrite powder of ferrite layer,
It is obvious to extraneous high-frequency interferencing signal and magnetic interference shield effectiveness, prevent that surrounding high-frequency signal is to transmission in signals transmission
The interference of content and steal, first time shielding is carried out to cable inner core using metallic shield net, using foaming, PE layers are protected,
Screen layer is prepared into using the method for PVA mixed ferrite powder between foaming PE layers and fire-retardant jacket layer, does not influence cable
The pliability of itself, there is wide applicability in shielded cable field.
