Description

Tone frequency channel wire

Technical field

A kind of wire is the utility model is related to, more particularly to a kind of tone frequency channel wire.

Background technology

Tone frequency channel wire is to play contact transmission between equipment and equipment in the acoustic system.The effect of communication, it is in whole sound In occupation of very important role in acoustic system.

Notification number is that CN203276921U utility model discloses a kind of counter-bending tone frequency channel wire, including core group, interior shield Jacket layer, bending resistance layer and jacket layer.In general, core group includes three conductor wire cores, each conductor wire core is connected with outside one Plug.Three conductor wire cores are interfixed by jacket layer.But one end that three conductor wire cores are connected with external plug needs It is separated from each other, therefore the jacket layer outside three conductor wire cores is separated from each other.So during use, jacket layer is mutual Distance can increase, cause tone frequency channel wire using or collapse when be easier to be intertwined, potential safety hazard be present, need Improve.

Utility model content

The purpose of this utility model is to provide a kind of tone frequency channel wire, and its advantage is to separate it between the conductor wire core in tone frequency channel wire After can engage again.

Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of tone frequency channel wire, including Three conductor wire cores, the outside of the every conductor wire core are provided with polyolefin insulation layer, the outside of the polyolefin insulation layer according to Secondary to be provided with screen layer, the outside of the screen layer is provided with PVC sheath layer, and the PVC sheath layer of both sides is provided with neck, middle part The PVC sheath layer be provided with and can be embedded in fixture block in neck.

By using above-mentioned technical proposal, by polyolefin insulation layer come insulating protection, pass through the extraneous electricity of screen layer isolation The effect that magnetic field influences, reduce transport loss.PVC sheath layer can protect the sandwich construction of inside not to be damaged.In three wires Core can separately be reconnected by the cooperation of fixture block and neck afterwards, avoid four wire cores from mutually winding.

The utility model is further arranged to：Also include all for three conductor wire cores being coated on interior nylon sheath wire layer.

By using above-mentioned technical proposal, nylon sheath wire layer is set to make while causing and improve protecting effect as spacing Obtaining three conductor wire cores can not be completely separable.

The utility model is further arranged to：The outer surface of the nylon sheath wire layer is provided with multiple annular half slots.

By using above-mentioned technical proposal, because the nylon sheath wire layer at this is relatively thin, scissors only needs to apply when cutting Add the power of very little can cut, avoid breaking the PVC sheath layer in nylon sheath wire layer.When tone frequency channel wire is wound in into a circle When, the deformation quantity of nylon sheath wire layer is concentrated mainly on half slot, can be avoided nylon sheath wire layer rupture when winding, be led Nylon sheath wire layer is caused to lose effect.

The utility model is further arranged to：The inner side of the nylon sheath wire layer is bonded completely with the outside of PVC sheath layer, The nylon sheath wire layer blocks to form sliding block along half slot.

By using above-mentioned technical proposal, sliding block is formed after being blocked by nylon sheath wire layer, when tone frequency channel wire plug not It when needing to separate excessive, can promote sliding block that fixture block can be caught in neck towards plug movement, avoid PVC sheath layer mutual Separation.So there is no need to slowly fixture block is caught in neck manually.

The utility model is further arranged to：The conductor wire core is twisted by 0.1MM copper free wire.

By using above-mentioned technical proposal, the conductor wire core being twisted by 0.1MM copper free wire, which has, preferably leads Electric rate, lower transmission losses.

The utility model is further arranged to：The screen layer includes aluminium foil layer and wire sheathing.

By using above-mentioned technical proposal, the effect of dual shield, Er Qiejin are played by aluminium foil layer and metal organization level Category braiding layer can increase the tensile strength of tone frequency channel wire so that tone frequency channel wire is not easy to be pulled off.

In summary, the beneficial effects of the utility model are：

1st, together with more conductor wire cores can be reconnected by the fit structure of fixture block and neck, will not arbitrarily dissipate Open, avoid tone frequency channel wire from being intertwined；

2nd, nylon sheath wire layer can limit the separated ultimate range of PVC sheath, and can cut and to form sliding block conveniently to incite somebody to action Fixture block is caught in neck.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

This specific embodiment is only that it is not to limitation of the present utility model, ability to explanation of the present utility model Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but As long as all protected in right of the present utility model by Patent Law.

As shown in figure 1, a kind of tone frequency channel wire, including three conductor wire cores 1 being twisted by 0.1MM copper free wire, lead The outside of wire core 1 is surrounded by polyolefin insulation layer 2.Aluminium foil layer 3 and wire sheathing are outwards surrounded by successively from polyolefin insulation layer 2 4, which are used as double layer screen layer, plays a part of completely cutting off external electromagnetic field influence, reduces transport loss.The outside of wire sheathing 4 PVC sheath layer 5 is surrounded by play the effect inside protection.

As shown in figure 1, neck 6 is provided with the PVC sheath layer 5 of both sides conductor wire core 1, the PVC shields of middle part conductor wire core 1 Integrally formed fixture block 7 is provided with jacket layer 5, the fixture block 7 can be caught in neck 6.When in use, due to three conductions Core 1 can be separated from each other, the mutual distance in one end that three conductor wire cores 1 of increase are connected with plug.When leading for separation When wire core 1 is excessive or needs to pack up tone frequency channel wire, the fixture block 7 on PVC sheath layer 5 can be caught in corresponding neck 6 Among, reduce the space shared by tone frequency channel wire, three conductor wire cores 1 are mutually wound when avoiding collapsing.

As shown in Fig. 2 the outside of nylon sheath wire layer 8 is provided with an annular half slot 9 every one end distance.When needing to shell From certain length nylon sheath wire layer 8 when, it is only necessary to first two side portions at half slot 9 are cut with scissors, then protected nylon Jacket layer 8 is outwards peeled off.Because the nylon sheath wire layer 8 at this is relatively thin, scissors only needs to apply the power of very little when cutting Cut, avoid breaking the PVC sheath layer 5 in nylon sheath wire layer 8.When tone frequency channel wire is wound in into a circle, nylon sheath wire layer 8 Deformation quantity be concentrated mainly on half slot 9, the nylon sheath wire layer 8 when winding can be avoided to rupture, cause nylon sheath wire Layer 8 loses effect.

As depicted in figs. 1 and 2, turn into sliding block 10 after portions of nylon restrictive coating 8 can be separated, when tone frequency channel wire plug not When needing to separate excessive, it can promote sliding block 10 that fixture block 7 can be caught in neck 6 towards plug movement, avoid PVC sheath layer 5 are separated from each other.
