Join polyolefin or silicon rubber as its insulation or sheath material, be widely used in automotive interior be connected by power and power battery pack in
Portion.Common cross-linked polyolefin bending wire radius is big, and conductor uses cage winch reverse stranding, and process velocity is slow, finished product conductor lines
Diameter is big, and wire rod is flexible poor, bending part easily season cracking due to fatigue when being bent use；Secondly mounting and installation when need compared with
Large space, laying space is small inside new energy passenger car or angle and curved is needed to be difficult in the environment of connection.Silicon rubber
Wire rod not oil resistant, scratch-resistant, is not punctured cracking easily, meets battery acid and is easily corroded cracking, and lettering is easy to fall off, and preparation section is multiple
Miscellaneous, material price is expensive, and production equipment and space limiting factor wait shorts of electricity more, can not large-scale promotion use.
Utility model content
The main purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of more soft, bending property
Well, oil resistant, high temperature resistant, long service life use relatively reliable composite high pressure line.
To achieve the above object, the utility model uses following technical scheme:
A kind of composite high pressure line, it is characterised in that: including center conductor, silicone insulation layer, woven shield, metal foil layer
And crosslinked polyethylene restrictive coating, the conductor outside are equipped with the silicone insulation layer, wrap up outside the silicone insulation layer
Woven shield is stated, is equipped with the metal foil layer outside the woven shield, the crosslinked polyethylene restrictive coating is surrounded on institute
It states outside metal foil layer.
Preferably, the center conductor is using the 6th class flexible conductor for meeting the requirement of GB/T 3956, and the conductor is by several
Root monofilament is twisted to be formed, and the filament diameter is 0.15mm.
After the monofilament bundle strand, 19 or 37 strands lines twist again form the center conductor in the same direction, using there is back twist when twisting again
The cage winch of device produces, and can eliminate and twist the stress generated because multiple, make wire rod more rounding, softness, consolidation.
Preferably, the woven shield is woven by the tinned copper wire of several filament diameter 0.15mm.
Preferably, the metal foil layer is formed by aluminium-plastic tape is wrapped, and the aluminium-plastic tape is preferably single side aluminium foil,
The overlap rate of the aluminium-plastic tape is not less than 25%.
As described above, composite high pressure line described in the utility model, with good wearability, high temperature resistance and excellent
Flexibility and higher corrosion resistance, electromagnetism interference performance, can be stronger etc. in high temperature, corrosivity and electromagnetic disturbance
It is used under conditions of severe.
Detailed description of the invention
Fig. 1 is the sectional view of the utility model composite high pressure line；
Fig. 2 is the overall structure diagram of composite high pressure line shown in Fig. 1.
Specific embodiment
It elaborates below to a kind of embodiment of composite high pressure line of the utility model.It is emphasized that following
Explanation is only exemplary, rather than in order to limit the scope of the utility model and its application.
Fig. 1 and Fig. 2 are please referred to, the utility model composite high pressure line includes the center conductor that more copper monofilament are twisted
19, the center conductor 19 is externally provided with the silicone insulation layer 20 being coaxially arranged, and the silicone insulation layer 20 is wrapped with volume
Shielded layer 21 is knitted, the woven shield 21 is wrapped with aluminum metal layers of foil 22, and it is poly- that the metal foil layer 22 is wrapped with crosslinking
Ethylene restrictive coating 23.
As further improvement of this embodiment, the center conductor 19 is using the 6th class for meeting the requirement of GB/T 3956
Flexible conductor, the conductor are formed by several monofilament are twisted, and the filament diameter is 0.15mm.
After the monofilament bundle strand, 19 or 37 strands lines twist again form the center conductor 19 in the same direction, using moving back when twisting again
The cage winch production for turning round device, can eliminate and twist the stress generated because multiple, make wire rod more rounding, softness, consolidation.
For the silicone insulation layer 20 while playing insulating effect, having cable, high pressure resistant, resilient flexible is excellent, super
The advantages that long ageing-resistant, fire-retardant, long service life.
As further improvement of this embodiment, the woven shield 20 by several filament diameter 0.15mm plating
Tin proof copper-wire braided forms, it is possible to prevente effectively from interference signal enters conductor, reduces the loss of transmission signal.
As further improvement of this embodiment, the metal foil layer 21 is formed by aluminium-plastic tape is wrapped, the plastic-aluminum
Composite band is preferably single side aluminium foil, and the overlap rate of the aluminium-plastic tape is not less than 25%.The metal foil layer 21 protects volume
Shielded layer 20 and 23 internal layer of crosslinked polyethylene restrictive coating are knitted, shields interference electrically and magnetically together with woven shield 20, effectively
It ensure that the conveying of forceful electric power and light current.
The crosslinked polyethylene restrictive coating 23 can play a protective role to cable, make the resistance to battery acid corrosion of whole electric wire,
Chemical resistance, water resistance, the puncture of resistance to sharppointed article etc. are all greatly improved, and cross-linking polyethylene materials also have
Good mechanical strength is extruded into crosslinked polyethylene restrictive coating 23 with the material, and substantially increase electric wire uses the longevity
Life and safety.
As further improvement of this embodiment, the thickness of the silicone insulation layer 20 is less than crosslinked polyethylene restrictive coating
23 thickness makes so doing silicone insulation layer of silicon rubber than crosslinked polyethylene because silicon rubber has excellent insulation performance
In the case that silicone insulation thickness degree is small, still there is excellent insulating properties, while whole wire rod line footpath all makes than insulation and sheath
It wants small with crosslinked polyethylene material, enhances electric wire softness, it is more convenient to be laid in the car.
In conclusion composite high pressure line described in the utility model, it is high pressure resistant, soft that the silicone insulation layer 20 has cable
The advantages that soft elasticity is excellent, overlength is ageing-resistant, fire-retardant, long service life；The crosslinked polyethylene restrictive coating 23 makes whole electric wire
The burn into of resistance to battery acid chemical resistance, water resistance, resistance to sharppointed article puncture etc. be all greatly improved, and be crosslinked
Polythene material also has good mechanical strength, is extruded into crosslinked polyethylene restrictive coating 23 with the material, greatly increases
The service life and safety of electric wire are added.The combination of the silicone insulation layer 20 and the crosslinked polyethylene restrictive coating 23 makes
With while improving insulating properties, avoiding layer of silica gel not oil resistant, not scratch-resistant, be easily punctured cracking, meet battery acid easily quilt
The problems such as corrosion cracking, lettering is easy to fall off, while whole gauge or diameter of wire all uses crosslinked polyethylene material than insulation and sheath
Want small, make electric wire softness enhance, it is more convenient to be laid in the car.
The above content is specific/preferred embodiment further detailed description of the utility model is combined, no
It can assert that the specific implementation of the utility model is only limited to these instructions.For the common skill of the utility model technical field
For art personnel, without departing from the concept of the premise utility, the embodiment that these have been described can also be made
Some replacements or modifications, and these substitutions or variant all shall be regarded as belonging to the protection scope of the utility model.
