Description
Technical field
The present invention relates to a kind of resist bending up to 200,000 superfine coaxial signal transmission cables, is mainly used in pen
The inside connection for remembering the digital products such as this computer, tablet computer, mobile phone, camera and some Medical Devices belongs to signal transmission electricity
Cable technical field.
Background technique
With the development trend of small-sized, frivolous, the high bending of 3C electronic product and medical product, conventional extremely thin coaxial wire is
It is unable to satisfy more to refine and the products application demand of higher bendability.
Summary of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and providing a kind of can reduce signal-transmitting cable
Outer diameter promotes the resistant to bending superfine coaxial signal transmission cable and production method of cable resistance to bend(ing).
The object of the present invention is achieved by the following technical solutions, a kind of resistant to bending superfine coaxial signal transmission electricity
Cable, it includes more coating coating alloy copper stranded conductors being twisted, that every diameter is no more than 0.020mm as intermediate
Conductor, the middle conductor outer layer have the fluoroplastic insulations such as PFA of the thickness less than 0.035mm by high temperature extrusion equipment extrusion molding
Layer, insulating layer outside are wound with more, coating coating alloy copper monofilament of the single diameter no more than 0.025mm using Wiring apparatus
Conductor, and shielded layer is formed, the shielded layer outer layer passes through the PFA that high temperature extrusion equipment extrusion molding has thickness to be less than 0.035mm again
Equal fluoroplastics restrictive coating.
As preferred: the middle conductor is mutually twisted by 7 coating coating alloy copper stranded conductors, and outside
Face is formed respectively with the cable product line outer diameter after the fluoroplastics restrictive coatings such as the fluoroplastic insulations such as PFA layer, shielded layer and PFA and is less than
0.25mm。
The present invention is selected due to inner conductor and shielded layer conductor with high intensity and with the special of more preferable fatigue resistance
Coating alloy copper product；Fluoroplastic insulations and the sheath materials such as high melting means PFA are selected, to ensure that the feasible of thin-walled extrusion molding
Property, to realize the miniaturization of line footpath；Therefore superfine coaxial signal transmission cable produced by the invention, resistance to bend(ing) are used
It can be obviously improved.
Detailed description of the invention
Fig. 1 is cross section structure schematic diagram of the invention.
Fig. 2 is 3 D stereo schematic diagram of the invention.
Specific embodiment
The present invention will be described in detail below with reference to the accompanying drawings: Fig. 1, shown in 2, and one kind of the present invention is resistant to bending
Superfine coaxial signal transmission cable, it includes more coating yellow golds being twisted, every diameter is not more than 0.020mm
Stranded conductor has thickness to be less than as middle conductor 1,1 outer layer of middle conductor by high temperature extrusion equipment extrusion molding
The PFA insulating layer 2 of 0.035mm, using Wiring apparatus is wound with more, single diameter is no more than 0.025mm's outside insulating layer 2
Coating yellow gold monofilament conductor 3, and shielded layer is formed, the shielded layer outer layer passes through high temperature extrusion equipment extrusion molding again thickness
PFA restrictive coating 4 less than 0.035mm.
As preferred embodiment, middle conductor 1 of the present invention is mutually twisted by 7 coating yellow gold stranded conductors
It closes, and is formed respectively with the cable product line outer diameter after PFA insulating layer 2, shielded layer 3 and PFA restrictive coating 4 outside and is less than
0.25mm。
A kind of production method of resistant to bending superfine coaxial signal transmission cable as described above, the production method include
Following steps:
(a) prepared by middle conductor: preparing single coating yellow gold monofilament conductor as required, takes 7 single coating silver-bearing coppers
Alloy filaments conductor unwrapping wire and is twisted into middle conductor together, and take-up is spare；
(b) prepared by PFA insulating layer: by middle conductor unwrapping wire, using PFA plastics by high temperature extrusion equipment extrusion molding, in
Between conductor outer layer be extruded into one layer of PFA insulating layer for wrapping middle conductor, then cooling and take-up；
(c) it winds shielded layer: the middle conductor line unwrapping wire of PFA insulating layer will be enclosed with, and set outside it using winding
It is standby to be wound with more coating yellow gold monofilament conductors, and after forming shielded layer, take-up；
(d) prepared by restrictive coating: the middle conductor line unwrapping wire after winding shielded layer is set using PFA plastics by high temperature extrusion
Standby extrusion molding, is extruded into one layer of PFA restrictive coating for wrapping shielded layer in the outer layer of shielded layer, then cooling and take-up, through examining
Qualification storage.
As preferred embodiment, in step (b) of the present invention, in middle conductor package PFA insulating layer through cooling
Manufactured single line afterwards, after the synchronization on-line checking of outer diameter monitor, concave-convex tester and spark test instrument, qualification is received
Line；
In the step (d), after the outer layer of shielded layer is extruded into one layer of PFA restrictive coating and cools down, outer diameter is also passed through
After the synchronization on-line checking of monitor, concave-convex tester and spark test instrument, qualified take-up, then enter after product inspection is qualified
Library.Example: Fig. 1, shown in 2, such as MCC46AWG-0.20mm；
Middle conductor 1: the silver-plated yellow gold monofilament of 7 0.016mm is twisted, and forms 46AWG strands conductor.
Insulating layer: expected using high temperature extrusion equipment in the PFA that conductor outer layer extrusion molding thickness is about 0.029mm, form insulation
Single line.
Winding shielded layer 3: more calculated in the winding of insulated single wire outer layer according to outer insulation diameter using special winding equipment
The silver-plated yellow gold monofilament conductor of 0.02mm forms shielding winding semi-finished product line；
Restrictive coating 4: being expected using high temperature extrusion equipment in the PFA that winding semi-finished product outer layer extrusion molding thickness is about 0.028mm, complete
At the production of product line.
The finished product outer diameter of above-mentioned superfine coaxial signal transmission cable is 0.20mm, and resistance to bend(ing) reaches 200,000 times or more (examinations
