Abstract
The utility model provides an audio control cable, belonging to the technical field of a cable. The audio control cable comprises a cable core and an outer sheath. The cable core is formed by a bare copper wire audio wire and a tinned copper wire audio wire. The bare copper wire audio wire is formed by sequentially extruding a polyethylene insulation layer, a braided metal shield layer and an extruded polyvinyl chloride inner sheath on a bare copper wire conductor. The tinned copper wire audio wire is formed by sequentially extruding a polyethylene insulation layer, a braided metal shield layer and an extruded polyvinyl chloride inner sheath on a tinned copper wire conductor. The audio control cable has a reasonable structure, the bare copper wire audio wire and tinned copper wire audio wire structures are employed, the distinction between an anode and a cathode is easy, and the wrong connection is prevented. Copper wire conductors are employed, the attenuation is reduced, the frequency of use of the cable is raised, and the scope of use is expanded. The polyethylene is employed to be an insulating material, the density is small, the dielectric loss angle is small, the performance is superior, and the quality of an audio data transmission signal is good. The braided metal shielding layers are employed, the cable shielding effect is strong, the mechanical properties and bending properties are good, and the service life is long.
Description
Technical field
This practical sexual type relates to a kind of cable, and a kind of structure of audio amplifier cable particularly belongs to the cable technology field.
Background technology
Signal transmission between the digital device in the stereo set system must be used cable interconnection, no matter be any standard, use the system equipment of what form, cable used is most important, sometimes ignored the AC characteristic of cable in a certain link, do not select the voice-frequency cable that rationally reaches the AC characteristic coupling, just can not reach best technical characteristic effect, can produce inconceivable adverse consequences.For signal transmission accurately, cable must be complementary with transmitting and receiving device.The digital electric signal frequency is very high, and during the characteristic impedance coupling, the kelvin effect of electric current on wire can be darker, and darker laser propagation effect is better.When not mating, the 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 the consumption signal energy, makes the distortion of digital pulse signal waveform generation.Distributed capacitance when 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 the transmission receiving terminal, during to the deciphering of digital signal, error code can appear, 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.Existing audio frequency control cable, shielding properties, flexibility are poor, and not antitorque, intensity is low, tension not, cable and equipment are not complementary, the audio data transmission dtr signal, useful life is shorter, can not satisfy instructions for use.
The utility model content
The purpose of this practical sexual type is exactly for the deficiencies in the prior art, is the demand of satisfying the market, and a kind of audio frequency control cable is provided.
The purpose of this practical sexual type is to realize like this, the audio frequency control cable, comprise cable core and oversheath, it is characterized in that 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 is by extruding successively polyethylene layer, braided metal screen, extrude polyvinyl chloride inner sheath and consist of on the bare copper wire conductor, described tinned copper wire tone frequency channel wire is by extruding successively polyethylene layer, braided metal screen on the tinned copper wire conductor, extruding polyvinyl chloride inner sheath and consist of.
Described oversheath is extruded on described cable core by polyvinyl chloride.
Be provided with insulation filler in described cable core.
Described bare copper wire conductor and tinned copper wire conductor structure are measure-alike.
This practical sexual type is rational in infrastructure, adopts bare copper wire tone frequency channel wire and tinned copper wire tone frequency channel wire structure, easily distinguishes both positive and negative polarity, can not cause wrong.Adopt the copper wire conductor, reduce decay, improve the cable frequency of utilization, enlarge the scope of application.Bare copper wire tone frequency channel wire and tinned copper wire tone frequency channel wire all adopt polyethylene to do the insulation material, and density is little, dielectric loss angle is little, superior performance, and the 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 the braided metal screen, and the cable shield effect is strong, mechanical performance, good bending property, long service life.
Description of drawings
Fig. 1 is the structural representation of this practical sexual type.
In figure: 1 conductor, 2 insulating barriers, 3 screens, 4 inner sheaths, 5 oversheaths.
Embodiment
The audio frequency control cable, consisted of by cable core and oversheath, 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 is by extruding successively polyethylene layer, braided metal screen, extrude polyvinyl chloride inner sheath and consist of on the bare copper wire conductor, described tinned copper wire tone frequency channel wire is by extruding successively polyethylene layer, braided metal screen on the tinned copper wire conductor, extruding polyvinyl chloride inner sheath and consist of.Described bare copper wire conductor and tinned copper wire conductor structure are measure-alike.Oversheath is extruded on described cable core by polyvinyl chloride.Be provided with insulation filler in cable core.
The audio frequency control cable adopts bare copper wire and tinned copper wire structure, easily distinguishes both positive and negative polarity, can not cause wrong.Adopt the copper wire conductor, reduce decay, improve the cable frequency of utilization, enlarge the scope of application.Bare copper wire tone frequency channel wire and tinned copper wire tone frequency channel wire all adopt polyethylene to do the insulation material, and density is little, dielectric loss angle is little, superior performance, and the 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 the braided metal screen, and the cable shield effect is strong, mechanical performance, good bending property, and long service life is met the need of market.
