Abstract
The utility model discloses an intorsion-resisting soft foaming type audio cable. A cable core adopts a pair-twisted cabling structure and comprises two insulating wire cores distributed in pair-twisting mode and a propene polymer (PP) filling rope arranged on the gap portion of the two insulating wire cores. An aluminum foil twisted shielding layer and a tinned copper wire woven shielding layer are sequentially arranged outside the cable core, and an outer sheath layer is arranged on the outermost layer of the cable. The intorsion-resisting soft foaming type audio cable is mainly used in transmission of audio signals and has the advantages of being low in working capacitance, good in transmission performance, inflaming retarding, intorsion-resisting, environment-friendly and the like.
Description
Technical field:
The utility model relates to the soft expansion type voice-frequency cable of a kind of antitorque strand.
Background technology:
No matter be music making equipment or acoustic playback equipment, voice-frequency cable is a part and parcel always, but considerable people and think little of it.The line that this is short or long, having slightly has thin core, and various joint; Undertaking the transmission work of voice data, and if the good music playback device of a cover, the suitable audio cable of not arranging in pairs or groups; Just can not reach best playback effect, sometimes even meeting " can't bear disastrously listen ".A lot of consumers are buying high-end sound card or in the home theater of establishment oneself, such problem arranged: is audio signal wire really so important? Much human has been spent ten of thousands yuan purchase power amplifier; Buy sound system, but last they all at will buy several common " electric wires " and connect audio amplifier.Audio signal wire becomes bottleneck maximum in the system thus.Expensive better again hardware also is difficult to give play to its advantage.
The audio signal cable more or less all can receive the interference of outside source energy in work obviously.Any interference, inhibition, annexation and distortion, the energy of signal all is called external interference signals in our cable.A lot of potential interference signals are arranged around the audio signal cable.The most typical source is exactly an electronic noise, for example the most familiar radio wave of people.When you transfer platform, can hear a lot of noisy sound.Radio antenna can be converted into aerial radio signal beautiful stereo music.Meanwhile aerial radio signal also can interfere with our audio signal cable.If you do not plan in music appreciating broadcast listening simultaneously, these aerial radio signals formidable enemy that just like is exactly audio signal wire so.
Mobile phone, microwave oven, electric light, sound wave or even the sun, they might create interference signal.Electronic equipment as mobile phone and microwave oven all can generate an electromagnetic field around, and these energy can directly be transformed in the audio signal cable.Sound wave can produce the very very high physical shock of small frequency of amplitude, and these energy also can influence the voltage of audio signal.Therefore interference signal has many different types.
Traditional audio signal wire; Adopt simple insulating material, and shielding construction, make signal in transmission course because decay is big, mutual capacitance is high; Characteristics such as perhaps cable intensity is low, not soft; Make this type of cable in use, tend to occur that noise is many, signal off and on, be inconvenient to use or the like characteristics.
Summary of the invention:
For overcoming the defective of prior art, the purpose of the utility model is to provide a kind of antitorque strand soft expansion type voice-frequency cable, has satisfied the deficiency that audio frequency apparatus is promoted, and is cheap, uses simple.
The utility model technical solution problem adopts following technical scheme:
The soft expansion type voice-frequency cable of antitorque strand; Cable core adopts pair twist to become cable structure; Cable core comprises two pair twists insulated wire cores of arranging and the PP gasket for packing that is arranged at two insulated core gap locations; Outside said cable core, be provided with the wrapped screen of aluminium foil, tinned copper wire woven shield successively, the outermost layer of cable is an external sheath layer.
Said insulated wire cores is made up of stranded conductor and foaming insulation layer.
Compared with present technology, the beneficial effect of the utility model is embodied in:
1, the insulating material of expansion type is adopted in the insulation of the utility model cable, and, good insulation preformance lower than previously used insulating material dielectric coefficient, mutual capacitance is low, decay is little, and transmission performance is stable, the quality height.
2, the utility model has adopted double-layer shielding structure, has reached 100% shielding, can shield various electromagnetic interference, and shield effectiveness is good, and has strengthened the tension and the twisting performance of whole cable.
3, the sheath material that adopts of the utility model is a neoprene, good mechanical properties such as intensity, toughness, softness, has fire resistance, in use can stand to pull and twisting.
4, the PP gasket for packing is adopted in the utility model cable space, has kept the roundness of cable and attractive in appearance.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Label among the figure: 1 external sheath layer, 2 tinned copper wire woven shields, 3 screens, 4 foaming insulation layers, 5 conductors, 6PP gasket for packing.
Below pass through embodiment, and combine accompanying drawing that the utility model is described further.
Embodiment:
Embodiment: referring to Fig. 1; The soft expansion type voice-frequency cable of the antitorque strand of present embodiment; Its cable core adopts pair twist to become cable structure, and cable core comprises two pair twists insulated wire cores of arranging and the PP gasket for packing 6 that is arranged at two insulated core gap locations, outside cable core, is provided with the wrapped screen of aluminium foil 3, tinned copper wire woven shield 2 successively; The outermost layer of cable is an external sheath layer 1, and external sheath layer adopts antiultraviolet, intensity height, good toughness, fire-retardant, soft neoprene.Insulated wire cores is made up of stranded conductor 5 and foaming insulation layer 4.
In the practical implementation, corresponding structure setting and material property are configured to:
The aforementioned conductor of the utility model is 1mm
2Adopt stranded the forming of annealed copper of monofilament 0.2, and its insulating material is the HDPE of expansion type, foam degrees 45%, dielectric coefficient is low, good electrical property, mutual capacitance is low.That external sheath layer adopts is soft, wear-resisting, waterproof, antiultraviolet, fire-retardant chloroprene rubber material, anti-ly pulls that performance is good, toughness is high, guarantees that cable in long-term mechanical performance and barrier propterty in use, has increased the useful life and the stability of cable.
