Description
Technical field
The present invention relates to a kind of hot-melt polyester band communication cable and preparation method thereof.
Background technology
Communication cable is the main medium for transmitting radio frequency signal, and it is that two that cored wire is formed with shielding net cylinder lead
Body, because the axle center of this two conductors is to overlap, therefore claim communication cable.Communication cable is by inner wire, insulation, outer conductor and shield
Four parts of jacket layer form：(1) inner wire is in cylindrical structure, has higher electrical conductivity, enough mechanical strength and necessity
Flexibility, be generally made up of a solid copper conductor, main material has:Annealed copper wire, annealing steel tube, copper-clad aluminum conductor；(2) absolutely
Edge decides the same core of internal and external conductor, therefore dielectric is except with higher insulating properties, should also have excellent machine
Therefore the selection of dielectric material and its structure are extremely important by tool performance, are mainly insulated at present using vinyon；(3) led outside
Body is crucial structural detail, when the shape of outer conductor is along the consistent hollow cylinder of total length desired homogeneous, then signal energy
Measure and axially transmitted along cable and the outer conductor without added losses and distortion communication cables has double action, it is both used as and is transmitted back to
A piece wire on road, generally to have 3 kinds of structures with shielding action, outer conductor:Tubular metal, aluminum plastic composite belt longitudinal bag are taken
Connect, mesh grid and aluminum plastic composite belt longitudinal package close；(4) the most frequently used sheath material of communication cable is igelite structure at present
Into.The outer conductor formed is closed by mesh grid and aluminum plastic composite belt longitudinal package to develop from single woven mesh structure, is had
The features such as flexibility is good, in light weight and joint is reliable, current this structure type are widely used, and more undeniable
It is that in present automation process, because being processed again after sometimes peeling off outer conductor and jacket layer, this is just
Sometimes occurring there is outer conductor layer has the situation of residual after peeling off, because aluminium-plastic tape uniquely relies on mesh grid pressing
It is vertical bag on insulator, once mesh grid is stripped and aluminium-plastic tape still has residual, without pressure force aluminium-plastic tape just
It can ftracture and tilt along overlapping, influence follow-up processing operation.
