There is inoxidizability, water proofing property, wear no resistance in general shielded signal, while its signal shielding layer
Setting is excessively single, can not shield strong electromagnetic wave interference, while setting too simpleization of its ground wire, while anti-pressure and abrasion-proof and curved
Bent ability is to be improved.
Invention content
The purpose of the present invention is to provide a kind of flexible polyolefin shielded signal lines of resistance to compression, to solve the prior art
Deficiency improves the jamproof ability of shielding, the ability of waterproof ability, oxidation resistant ability, anti-pressure and abrasion-proof and bending of cable.
Technical scheme of the present invention:
A kind of flexible polyolefin shielded signal line of resistance to compression, which is characterized in that including red copper wire and wrap up red copper wire
First polyolefin layer, first polyolefin layer form electromagnetic wave proof layer outside, and the outer surface of the electromagnetic wave proof layer is formed
The setting of the hemisphere jut and groove being interspersed, protrusion and groove increases the absorption area of electromagnetic wave, can absorb more
Electromagnetic wave, there is better electromagnetic wave proof performance, the signal to provide high quality provides condition, the electromagnetic wave proof
The first ground wire of layer connection, the electromagnetic wave proof layer form the second polyolefin layer, aluminium are formed outside second polyolefin layer outside
Mesh grid shielded layer is moored, the aluminum foil mesh grid shielded layer connection second is grounded, the setting of aluminum foil mesh grid shielded layer, first mistake
Part electromagnetic wave has been filtered out, the electromagnetic wave of different wave length is absorbed, has been conducive to double-deck electromagnetic wave proof, the aluminum foil braiding
Graphite anti oxidation layer is formed outside net shielded layer, is formed waterproof layer outside the graphite anti oxidation layer, is formed outside the waterproof layer wear-resisting
Layer, first ground wire and the second ground wire connect, and the density of second polyolefin layer is from axial up/down end face to side
End face is gradually successively decreased, and the anti-pressure ability of upper and lower side can be made to enhance, while the bending ability of side being made to improve, the electromagnetic wave
Protective layer is a conducting plastics layer.
First ground wire and the second ground wire connect.
The waterproof layer is pure acrylic acid polymeric layer.
The thickness of the graphite anti oxidation layer is 0.5 ~ 0.7mm.
The thickness of the waterproof layer is 0.5 ~ 0.9mm.
Advantageous effect：The shielding that a kind of flexible polyolefin shielded signal line of resistance to compression of the present invention effectively improves cable is anti-
The ability of interference, the ability of waterproof ability, oxidation resistant ability and anti-pressure and abrasion-proof and bending.
