Abstract
The utility model discloses a novel audio transmission and control cable used for automobile sound, comprising a core part which is formed by stranding three groups of insulated core pairs and two independent insulated cores; each insulated core pair is formed by stranding two cores; an insulating sleeve is sleeved outside each core; a first braid shielding layer is arranged outside each insulated core pair; the every two pitches stranded by the three groups of insulated core pairs are different; and a tinfoil shielding layer, a second braid shielding layer and a sheathing layer are sequentially sleeved outwards outside the core part. In the utility model, the audio transmission and control cable adopts three layers of shielding, the stranding pitches between every two wires are different, the sheathing layer adopts polyvinyl chloride material, thereby realizing the transmission of power as well as the control circuit and signal simultaneously, not only transmitting the power supply control signal, but also transmitting the analog and digital signals.
Description
Technical field
The utility model relates to a kind of automobile audio audio transmission and control cable.
Background technology
With the data cable is the automotive electronics line products of representative, and the application on automobile is more and more general, also more and more higher, the high serviceability of transmission digit rate.Therefore, in order to prevent electromagnetic interference and to satisfy of the heatproof requirement of each big motor corporation, very high requirement is proposed also for the construction of cable and material to automobile electric wire.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of novel automobile acoustic audio transmission and control cable, can improve the antijamming capability of cable greatly, takes into account the transmission of power supply and control circuit thereof and signal simultaneously.
For achieving the above object, a kind of novel automobile acoustic of the utility model audio transmission and control cable, comprise: core, by three groups of insulated wire cores to two stranded formation of independent insulated wire cores, every described insulated wire cores is to by two stranded forming of core, every core outer cover is provided with insulating case, and every described insulated wire cores is provided with first woven shield to the outside, and the pitch of three groups of described insulated wire cores strands is different in twos; Outside at described core outwards also is set with tinfoil paper screen, second woven shield and restrictive coating successively.
Preferably, also be filled with the non-hygroscopic filler in the space between described foil shielding layer and described core.
Preferably, described first woven shield and second woven shield adopt copper wire or tinned copper wire braided material.
Preferably, described restrictive coating adopts high temperature resistant pvc material.
Preferably, described insulating case adopts high temperature resistant pvc material, PP (polypropylene) material or XLPE (crosslinked polyethylene) material.
This utility car sound equipment adopts three layers of shielding construction being made up of first woven shield, second woven shield and foil shielding layer with audio transmission and control cable, and make insulated wire cores in twos between the twisting pitch difference, restrictive coating adopts pvc material, thereby realized taking into account simultaneously the transmission of power supply and control circuit and signal, can transmit the electrical source of power control signal, again can transportation simulator and digital signal.Not only can guarantee the stability of mutual capacitance, and improve the antijamming capability of cable greatly, reduce the decay of signal.This cable can separate single to using, and also can manyly can transmit the multichannel unlike signal to using simultaneously, and anti-stop signal disturbs, and has improved the effectiveness of cable, has reduced and has repeated to spread line in the car, solves the limited problem of automobile shop space of lines.
Description of drawings

Fig. 2 is novel automobile acoustic of the present invention audio transmission and control cable longitudinal profile schematic diagram.
Embodiment
Below in conjunction with drawings and Examples the utility model automobile audio is elaborated with audio transmission and control cable.
As shown in Figure 1, 2, the utility model comprises: core 1, this core 1 by three groups of insulated wire cores to 2 and two independent insulated wire cores 7 stranded formation, that is to say, three groups of insulated wire cores twist together 2, the twisting pitch difference of Xing Chenging between any two, three groups of insulated wire cores are used for transmitting audio signal to 2, and two independent insulated wire cores 7 are used for the control signal of transferring electric power power supply.Every eradication edge core thoroughly does away with edge cores 23 stranded forming to 2 by two, and every eradication edge core 23 outsides are equipped with one deck insulating case 22.Every eradication edge core is provided with one deck woven shield 21 to 2 outer cover.Outside at core 1 outwards also is set with foil shielding layer 3, woven shield 4 and restrictive coating 5 successively.Here, woven shield 4,21 adopts copper wire or tinned copper wire braided material, and restrictive coating 5 adopts high temperature resistant pvc material, and insulating case 22 adopts high temperature resistant pvc material, also can adopt PP (polypropylene) material or XLPE (crosslinked polyethylene) material.In addition, also be filled with non-hygroscopic filler 6 in the space between tinfoil paper layer 3 and core 1.Insulated wire cores 23 adopts 7 stranded forming of tinned copper wire, and the diameter of tinned copper wire is 0.21mm.
The utility model automobile audio is formed so that different pitches is stranded 2 by 3 groups of insulated wire cores with control cable with audio transmission, and electromagnetic phase mutual interference in the time of can reducing line to transmission signals reduces the decay of signal.
In addition, the utility model automobile audio uses audio transmission and control cable owing to adopt three layers of reinforcement shielding, and shielding of pair twist branch and set shield, so this control cable antijamming capability is better than traditional signal controlling cable.In addition, because the space in the automobile is limited, be unfavorable for distributing of heat, cause the overheated phenomenon of local temperature easily, therefore, traditional heatproof is that 70 ℃ cable meets the demands, so require to adopt resistant to elevated temperatures insulating material and sheath material, control cable of the present utility model meets the requirements fully.
In addition, the utility model automobile audio adopts with audio transmission and control cable and many insulated wire cores is made up, every pair of core adopts different pitches, avoided line to cross-talk and mutual interference mutually.
In addition, screen 4,24 all adopts copper wire or tinned copper wire braiding to form, and count can reach more than 80%, and shield effectiveness is good, and simultaneously, the thin copper wire programming structure has improved the flexibility of cable, is convenient to move lay.
In sum; it below only is preferred embodiment of the present utility model; be not to be used to limit protection range of the present utility model; therefore; all any modifications of within spirit of the present utility model and principle, being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
