Abstract
The utility model relates to a four core star-quad microphone connection cable which comprises a cable core and an outer sheath. The cable is characterized in that the cable core is formed by twisting four audio wires; each audio wire is formed by sequentially extruding a polyethylene insulation layer, a spiral wrapping copper wire shielding layer and an extrusion polyvinyl chloride inner sheath on a copper wire conductor; the number of copper wire is 2*57; the filament diameter is 0.1mm; and the outer diameter of the cable is 6.2mm. According to the utility model, the structure is reasonable; the structure of silver plated copper wire audio wires and tinned copper wire audio wires is used; positive and negative poles can be easily distinguished; wrong connection is prevented; the silver plated copper wire audio wires and the tinned copper wire audio wires use polyethylene as insulating materials, and have the advantages of small density, small dielectric loss angle, superior performance and good audio data transmission signal quality; and the silver plated copper wire audio wires and the tinned copper wire audio wires use double spiral wrapping copper wire shielding layers, so that the cable has the advantages of strong shielding effect, great mechanical property and bending property and long service life.
Description
Technical field
The utility model relates to a kind of cable, and particularly a kind of structure of audio amplifier cable, belong to the cable technology field.
Background technology
Signal transmission between digital device in the 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 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.While 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 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 the 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.Existing two core microphone stube cables, 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 meet instructions for use.
The utility model content
The purpose of this utility model is exactly for the deficiencies in the prior art, is the demand of satisfying the market, and a kind of four-core star quad stranding microphone stube cable is provided.
The purpose of this utility model is to realize like this, four-core star quad stranding microphone stube cable, comprise cable core and oversheath, it is characterized in that described cable core is by four tone frequency channel wire stranded compositions, described tone frequency channel wire by on the copper wire conductor, extruding successively polyethylene layer, spiral winding shielding layer of copper wires, extrude polyvinyl chloride inner sheath and form, described copper wire radical is 2 * 57, and filament diameter is 0.1 ㎜, and the outside diameter of cable is 6.2 ㎜.
Described oversheath is extruded on described cable core by polyvinyl chloride.
In described cable core, be provided with insulation filler.
Described copper wire conductor is silver-gilt copper wire and tinned copper wire, and silver-gilt copper wire conductor and tinned copper wire conductor structure are measure-alike.
Described spiral winding shielding layer of copper wires is that double helix is wound around shielding layer of copper wires.
The utility model is rational in infrastructure, adopts silver-gilt 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.Silver-gilt 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.Silver-gilt copper wire tone frequency channel wire and tinned copper wire tone frequency channel wire all adopt and all adopt double helix to be wound around shielding layer of copper wires, and the cable shield effect is strong, mechanical performance, good bending property, long service life.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 conductor, 2 insulating barriers, 3 screens, 4 inner sheaths, 5 oversheaths.
Embodiment
