Wiring stripping is highly difficult for the family of no specific purpose tool.
The content of the invention
Poor for prior art shielded cable shielding action, stripping is difficult and easily causes conduction copper core infringement,
Increase termination resistance causes impedance to change and can not transmit the technological deficiency of high-frequency data signal, and the utility model provides one kind
Strong shielding easy-strip cable, on the basis of original shielding stratum reticulare, ferrite layer is added, suppresses high frequency using ferrite powder
Interference signal by preventing the interference in outer bound pair signals transmission and stealing, drastically increase the shielding of shielding line
Effect, tear line is added, outer jointing jacket is torn, simple to operate, cost is cheap, can not injure conduction in wire stripping
Copper core.
The technical scheme that the utility model is provided is as follows：
The utility model provides a kind of strong shielding easy-strip cable, including conduction copper core, ferrite layer, inner protective layer and
Fire-retardant overcoat, conduction copper core are surrounded by cable core filler, and conduction copper core and cable core filler are externally provided with metallic shield net, metal
Gauze screen is wrapped with inner protective layer, tear line is enclosed with inner protective layer side wall, tear line is externally provided with tear line integument, interior

It 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, PVA glue layers are coated outside tear line.
In the utility model, tear line is triangle.
In the utility model, ferrite powder last layer is coated outside tear line.
In the utility model, cable core filler is glass fiber.
In applicable the utility model device, lower cable is concordantly cut, gently double swerve the end of a thread, around tear line
Ferrite powder or organic glue layer activity pine, outwards tilt tear line using bottle opener, tear line integument and fire-retardant outer
Set is uniformly torn apart, and is successively pulled tear line and tear line integument tearing port to carry out wire stripping with pliers, is used again after wire stripping manual
Remove the catch net and cable core filler of the inside, you can wiring.
The beneficial effects of the utility model：
A kind of strong shielding easy-strip cable described in the utility model, electromagnetism is carried out using the ferrite powder of ferrite layer
Shielding, it is obvious to extraneous high-frequency interferencing signal and magnetic interference shield effectiveness, prevent surrounding high-frequency signal in signals transmission
Interference to transferring content and steal, cut tear line integument and fire-retardant overcoat using tear line, then heaved out with pliers
The tear line integument of tear shuts down inner protective layer, be torn by hand metallic shield net and internal cable core filler can wiring,
Whole process does not have longitudinally cutting operation, will not injure cable conduction copper core, has extensive be applicable in strong shielded cable field
Property.
