Description
Technical field
It the utility model is related to automobile electric wire technical field, more particularly to a kind of signal wires.
Background technology
In the prior art, the electric wire that all kinds automobile and the anti-signal interference position of other electrical equipment use, mostly 2x0.5mm
Twisted wire, foil shielding layer or copper wire establishment shielding, and state no interference signal export line.Its shortcoming is that interference signal wave screen is covered not
Thoroughly, slight interference signal be present；Interference signal it is relatively strong or to semaphore request it is higher when, it is impossible to meet to require well.
Utility model content
The purpose of this utility model is to provide a kind of signal wires for improving interference free performance.
To achieve these goals, the utility model provides following technical scheme：
A kind of signal wires disclosed in the utility model, including：
Insulated wire cores component, the insulated wire cores component include two insulated wire cores；
Export line is disturbed, it is described to disturb export line mutually circumscribed with two insulated wire cores respectively；
Restrictive coating, the restrictive coating are pvc sheath layer, the restrictive coating be arranged at the interference export line, two
The outer ring of insulated wire cores；
The interference export line and two insulated wire cores surroundings are filled with filler.
Further, be provided with screen layer on the inside of the restrictive coating, the screen layer parcel interference export line and
Insulated wire cores component.
Further, the screen layer is plastic-aluminum combined screen layer.
Further, the filler is polypropylene rope filler.
In the above-mentioned technical solutions, a kind of signal wires provided by the utility model, the anti-interference of electric wire substantially increase；
State no interference signal in electric appliance circuits and in electrical work environment；Meanwhile it is suitable for using in hot environment.
Brief description of the drawings
, below will be to institute in embodiment in order to illustrate more clearly of the embodiment of the present application or technical scheme of the prior art
The accompanying drawing needed to use is briefly described, it should be apparent that, drawings in the following description are only described in the utility model
Some embodiments, for those of ordinary skill in the art, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of structural representation for signal wires that the utility model embodiment provides.
Description of reference numerals：
1st, insulated wire cores；2nd, export line is disturbed；3rd, restrictive coating；4th, screen layer；5th, filler.
Embodiment
In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with accompanying drawing pair
The utility model is further detailed.
It is shown in Figure 1；
A kind of signal wires of the present utility model, including：
Insulated wire cores component, insulated wire cores component include two insulated wire cores；
Export line is disturbed, disturbs export line mutually circumscribed with two insulated wire cores respectively；
Restrictive coating, restrictive coating are pvc sheath layer, restrictive coating be arranged at interference export line, two insulated wire cores it is outer
Circle；
Interference export line and two insulated wire cores surroundings are filled with filler.
Preferably, screen layer, screen layer Oxidize export line and insulation are provided with the present embodiment on the inside of restrictive coating
Core component.
Wherein, screen layer is plastic-aluminum combined screen layer in the present embodiment.Filler is polypropylene rope filler.
Signal wires disclosed in the present embodiment are mainly used in acoustic navigation instrument on automobile, GPS positioning system, reverse image etc.
Connecting line；Meanwhile the electrical equipment such as TV, projecting apparatus can be used；And other various electrical appliance connecting wires.
This product is by dedicated extruder, and mould closely squeezes 105 DEG C of polyvinyl chloride of heatproof and conductive polyvinyl chloride
Bag is on conductive copper wire core.Wherein, extruder temperature is arranged to：One section 160 DEG C, two sections 165 DEG C, three sections 170 DEG C, four section 180
DEG C, 180 DEG C of head.Note：Temperature allows excursion ± 10 DEG C, and then, 3 solid conductors are twisted together with wire twisting machine,
Lay 30-35mm；After the completion of twisted, screen layer is packed with aluminium-plastic tape on the cored wire after twisted, coverage rate is more than
100%.105 DEG C of soft insulation of polyvinyl chloride of heatproof are finally extruded on the core woven.Wherein, extruder temperature is arranged to：
One section 160 DEG C, two sections 165 DEG C, three sections 170 DEG C, four sections 180 DEG C, 180 DEG C of head.Note：Temperature allows excursion ± 10 DEG C.
This product is basically identical with existing product when installing and using, and can use general peeling machine, and peeling, pressure side is sub,
Connection line.But black export line must be connected on the zero line or ground wire of circuit, so as to which interference signal is exported, avoid doing
Disturb.
In the above-mentioned technical solutions, a kind of signal wires provided by the utility model, the anti-interference of electric wire substantially increase；
State no interference signal in electric appliance circuits and in electrical work environment；Meanwhile it is suitable for using in hot environment.
Some one exemplary embodiments of the present utility model are only described by way of explanation above, undoubtedly, for
One of ordinary skill in the art, can be with a variety of in the case of without departing from spirit and scope of the present utility model
Mode is modified to described embodiment.Therefore, above-mentioned accompanying drawing and description are inherently illustrative, should not be construed as
Limitation to the utility model claims protection domain.
