Description
Technical field
The present invention relates to a kind of tone frequency channel wire line and preparation method thereof, especially a kind of Hi-fi audio line and preparation method thereof.
Background technology
Along with the development of sound technique, people are more and more higher to asking most of high-fidelity, except to stereo set, outside source of sound, player, loudspeaker or the like requirement, some auxiliary appliances especially connect the design and the quality of wire rod, also can directly have influence on the tonequality of broadcast.For now, the structure of tone frequency channel wire is made up of inner core, packed layer, screen and insulating outer layer substantially, wherein for screen, generally be to adopt a kind of wire to twine or be woven into wire netting to form, insulating outer layer then all is to adopt opaque PVC to be made, and outward appearance is plain.
Summary of the invention
The purpose of this invention is to provide a kind of Hi-fi audio line, outward appearance better appearance when screen has better shield effectiveness.
Another object of the present invention provides a kind of method of making above-mentioned Hi-fi audio line.
The present invention realizes above-mentioned purpose like this:
Hi-fi audio line comprises heart yearn, packed layer, screen and external insulation layer from the inside to the outside, and described screen along heart yearn external spiral is entwined side by side by the wire of two kinds of colors at least, and described external insulation layer is the transparent PVC layer.
As improvement of the technical scheme, the wire of described screen is respectively tinned copper wire and bare copper wire.
As further improvement in the technical proposal, the wire of described screen is respectively tinned copper wire and day plain silk.
As further improvement in the technical proposal, described heart yearn is by bare copper wire or bare copper wire and cored wire conductor that day plain silk mixes and be coated on cored wire conductor insulating barrier outward and form.
As further improvement in the technical proposal, described packed layer comprises cotton thread layer and cotton paper, and described cotton thread layer and heart yearn spiral are stranded, and described cotton paper is coated on outside both.
A kind of method of making Hi-fi audio line is characterized in that comprising following processing step:
A. with heart yearn and cotton thread according to clockwise or counterclockwise stranded with playing thigh machine spiral;
B. outside stranded heart yearn and cotton thread layer, twine cotton paper;
C. with wrapping machine the wire of at least two kinds of colors proportionally is wrapped in cotton paper side by side and forms screen outward;
D. outside screen, coat external insulation layer with extruder.
As the improvement of above-mentioned technology, the winding direction wiry of two kinds of colors of described screen is opposite with the spiral direction of lay of heart yearn and cotton thread.
As the further improvement of above-mentioned technology, the manufacturing process of described heart yearn is: the plain silk in sky is proportionally mixed with bare copper wire, and at its external application extruder coated insulation layer.
The invention has the beneficial effects as follows: screen is to adopt the wire of two kinds of colors to be entwined, and can be shown owing to insulating barrier forms helical pattern by transparent screen, and is attractive in appearance beautiful, and manufacture craft is simple.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the profile of first kind of embodiment of the present invention;
Fig. 3 is the profile of second kind of embodiment of the present invention.
Embodiment
See figures.1.and.2, Hi-fi audio line, comprise heart yearn 1, packed layer 2, screen 3 and external insulation layer 4 from the inside to the outside, described screen 3 is entwined along heart yearn 1 external spiral side by side by at least two kinds of colors are wiry, and described external insulation layer 4 is the transparent PVC layer, screen 3 is to adopt the wire of two kinds of colors to be entwined, and can be shown owing to external insulation layer 4 forms helical pattern by transparent screen 3, and is attractive in appearance beautiful.
The wire of wherein said screen 3 is respectively tinned copper wire and bare copper wire.Adopting tinned copper wire is because the two color is different with bare copper wire, and is more common in the industry wire rod, obtains than being easier to.If following at what have relatively high expectations when allowing, can replace with a day plain silk to bare copper wire, this is because a day plain silk has better conducting effect to high-frequency signal, just can improve screen 3 shield effectiveness of high-frequency signal to external world.
Described heart yearn 1 is by bare copper wire or bare copper wire and cored wire conductor 11 that day plain silk mixes and be coated on cored wire conductor 11 insulating barriers 12 outward and form.Bare copper wire is made comparatively simple, cheap, if require under the condition with higher, can adopt bare copper wire and day plain silk mixing manufacture, can improve the conducting effect of high-frequency signal equally, with reference to Fig. 3.
In addition, the effect of packed layer 2 is, one, increase the tension and the bending resistance of tone frequency channel wire; Two, play the effect of isolating heart yearn 1 and screen 3; Three, be convenient to the coating of screen 3; Four, play heat-blocking action, prevent external insulation layer 4 operations scald heart yearn 1.Described packed layer 2 comprises cotton thread layer 21 and cotton paper 22, and described cotton thread layer 21 is stranded with heart yearn 1 spiral, and described cotton paper 22 is coated on outside both.Cotton thread layer 21 mainly is tension, the bending resistance that improves tone frequency channel wire, fills the space of heart yearn 1, makes that the appearance after twining is comparatively smooth, and cotton paper 22 then is to play to isolate and adiabatic effect.
The present invention also provides the manufacture craft of Hi-fi audio line, and is as follows:
A. heart yearn 1 and cotton thread is stranded with playing strand machine spiral according to the direction of left-handed or dextrorotation;
B. at stranded heart yearn 1 and cotton thread layer 21 outer wrapping cotton paper 22;
C. with wrapping machine the wire of at least two kinds of colors proportionally is wrapped in the cotton paper 22 outer screens 3 that form side by side;
D. outside screen 3, coat the transparent PVC layer with extruder.
Above-mentioned manufacturing process is simple, and with low cost.
Because heart yearn 1 is that spiral is stranded according to a certain direction with packed layer 2, and heart yearn 1 and packed layer 2 twine appearance and the out-of-flatness that forms, if the spiral winding direction of screen 3 is identical, the metal wire of screen 3 will embed between heart yearn 1 and the packed layer 2, can cause screen 3 out-of-flatnesses equally, one side can influence attractive in appearance, also can influence the shielding properties of screen 3 on the other hand.Preferred fabrication mode of the present invention for this reason is that the winding direction wiry of 3 two kinds of colors of screen is opposite with the spiral direction of lay of heart yearn 1 and cotton thread, can guarantee that like this screen 3 has evenness preferably.
Adopt plain of sky and bare copper wire to mix situation about using at heart yearn 1, its manufacturing process is: sky element silk is proportionally mixed with bare copper wire, and at its external application extruder coated insulation layer 3, also be the simple of ten minutes.
