Abstract
The invention relates to an HTP microphone cable and belongs to the cable technology field. The HTP microphone cable comprises a cable core and an outer sheath. The HTP microphone cable is characterized in that the cable core comprises two audio wires, each audio wire is formed by a copper wire conductor which is externally and sequentially extruded by a polyethylene insulation layer, a vertical covering aluminum foil layer, a copper wire braiding shielding layer and an extrusion polyvinyl chloride inner sheath layer, the copper wire conductor is a stranded copper wire conductor, a diameter of a single wire is 0.1mm, an outer diameter of the cable is 6.0mm, and colors for inner sheaths of the two audio wires are different for easy differentiation. The HTP microphone cable has a reasonable structure, employs a structure comprising a bared copper wire audio wire and a tinned copper wire audio wire and different colors for easy differentiation, is easy to realize anode and cathode differentiation and avoids connection errors; a polyethylene material is employed to make the insulation material, so the density is small, a medium loss angle is small, the performance is excellent, and quality of an audio data transmission signal is good. The HTP microphone cable employs the braiding metal shielding layer and further has advantages of strong cable shielding effect, good mechanism and bending performance and long service life.
Description
Technical field
The present invention relates to a kind of cable, particularly a kind of structure of microphone cable, belongs to technical field of cables.
Background technology
Existing microphone cable, shielding properties, flexibility are poor, and not antitorque, intensity is low, tension not, cable and equipment do not match, audio data transmission dtr signal, useful life is shorter, can not meet instructions for use.Signal transmission between digital device in stereo set system must be used cable interconnection, no matter be any standard, apply the system equipment of what form, cable used is most important, sometimes in a certain link, ignored the AC characteristic of cable, do not select the voice-frequency cable that rationally reaches AC characteristic coupling, just can not reach best technical characteristic effect, can produce inconceivable adverse consequences.For signal transmission accurately, cable must match with transmitting and receiving device.Distributed capacitance while not mating due to cable resistance in cable, distributed inductance, resistance can directly affect the frequency response in signal, affect rising edge and the trailing edge time of pulse, at transmission receiving terminal, during to the deciphering of digital signal, there will be error code, if the skew of the front and back on rising edge of a pulse time and trailing edge time of occurrence, can cause the shake time long and reduced the quality of audio frequency, even can produce noise and make tonequality deteriorated.Digital electric signal frequency is very high, and during characteristic impedance coupling, the kelvin effect of electric current on wire can be darker, and darker laser propagation effect is better.While not mating, collection skin can be more shallow, and laser propagation effect is also just poorer, and this is because large multiple current in cable forms reflection, can produce standing wave and consumption signal energy, makes the distortion of digital pulse signal waveform generation.
Summary of the invention
Object of the present invention is exactly the deficiency existing for above-mentioned prior art, for meeting the demand in market, provides a kind of HTP microphone cable.
The object of the present invention is achieved like this, HTP microphone cable, comprise cable core and oversheath, it is characterized in that described cable core is comprised of two tone frequency channel wires, described tone frequency channel wire by extruding successively polyethylene layer, vertical aluminium foil layer, proof copper-wire braided screen on copper wire conductor, extrude polyvinyl chloride inner sheath and form, described copper wire conductor is copper wire stranded conductor, filament diameter is 0.1 ㎜, cable external diameter is 6.0 ㎜, and the inner sheath of two tone frequency channel wires is provided with the color for distinguishing.
Described oversheath is extruded on described cable core by polyethylene.
In described cable core, be provided with filler.
The present invention is rational in infrastructure, adopts the inner sheath of two tone frequency channel wires to be provided with the color for distinguishing, and easily distinguishes both positive and negative polarity, can not cause wrong.Adopt copper wire conductor, reduce decay, improve cable frequency of utilization, expand the scope of application.Copper wire stranded conductor can adopt bare copper wire and tinned copper wire, all adopts polyethylene to do insulating material, and density is little, dielectric loss angle is little, superior performance, and audio data transmission signal quality is good.Bare copper wire tone frequency channel wire and tinned copper wire tone frequency channel wire all adopt and all adopt braided metal screen, and cable shielding effect is strong, mechanical performance, good bending property, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1 conductor, 2 insulating barriers, 3 screens, 4 inner sheaths, 5 oversheaths, 6 aluminium foil layers.
Embodiment
HTP microphone cable, consists of cable core and oversheath, and oversheath is extruded on described cable core by polyethylene, fills insulation filler in cable core.Described cable core is comprised of bare copper wire tone frequency channel wire and tinned copper wire tone frequency channel wire, described bare copper wire tone frequency channel wire by extruding successively polyethylene layer 2, vertical aluminium foil layer 6, braiding shielding layer of copper wires 3 on bare copper wire conductor, extrude polyvinyl chloride inner sheath 4 and form, described bare copper wire conductor and tinned copper wire conductor structure are measure-alike.HTP microphone cable, adopts bare copper wire and tinned copper wire structure, and on the inner sheath of two tone frequency channel wires, establishes the color for distinguishing, and easily distinguishes both positive and negative polarity, can not cause wrong.Adopt copper wire conductor, reduce decay, improve cable frequency of utilization, expand the scope of application.Bare copper wire tone frequency channel wire and tinned copper wire tone frequency channel wire all adopt and all adopt braided metal screen, and cable shielding effect is strong, mechanical performance, good bending property, and long service life, meets the need of market.Bare copper wire tone frequency channel wire and tinned copper wire tone frequency channel wire all adopt polyethylene to do insulating material, and density is little, dielectric loss angle is little, superior performance, and audio data transmission signal quality is good.
