Description
Technical field
The utility model relates to wiring harness for vehicles technical fields, and in particular to a kind of soft aluminium alloy fire-resistant wire of vehicle.
Background technique
With increasing substantially for automotive performance and function, more to the flame retardant property of automobile electric wire, heat resistance performance requirement
It is high.Since copper is heavier, it is unfavorable for mitigating complete vehicle weight, therefore the conductive material of aluminum or aluminum alloy becomes focus concerned by people,
And since the mechanical performance of aluminum steel, creep resistance are poor, so that it is received obstruction in the application of automobile cable.Therefore automobile electric wire
Flame retardant property, high temperature resistance and safety and vehicle structure optimization design between there are still biggish contradictions.
Utility model content
The applicant provides a kind of structurally reasonable soft aluminium alloy of vehicle for the disadvantage in above-mentioned existing production technology
Fire-resistant wire, to solve that the mechanical performance of aluminum steel, creep resistance are poor to be led to electric wire for automobile save the cost, mitigate weight and mention
There is technical issues that between high flame resistance, high temperature resistance.
Technical solution used by the utility model is as follows:
The soft aluminium alloy fire-resistant wire of a kind of vehicle, including the cable core that at least one is made of conductive core, insulating layer, cable core
Outer braid have sheath；Diameter made of the conductive core is drawn as 8 line aluminium alloys is the thin aluminium alloy of 0.25mm~0.5mm
Tow twists.
Its further technical solution is:
Insulating layer is extruded in the outside of conductive core using flame-retardant organosilane cross-linked poly-ethylene.
Sheath is using the composite glass fiber silk knitting forming after impregnating ptfe emulsion.
The composite glass fiber silk of sheath uses the weaving manner knitting forming of 8 ingots, 16 ingots or 24 ingots.
After the thin aluminum-alloy wire bundle strand that conductive core is 0.25mm~0.5mm by diameter, 300 were heated up to by 1~2 hour
~350 DEG C, then formed after keeping the temperature 4~5 hours.
After the thin aluminum-alloy wire bundle strand that conductive core is 0.25mm~0.5mm by diameter, annealed treated filament strength
>=15%, alternating bending frequency >=25 time.
The beneficial effects of the utility model are as follows:
The utility model it is compact-sized, it is light-weight, and have good fire-retardant, heat resistance and flexibility, be suitable for ring
- 40 DEG C of range~200 DEG C of border temperature generate in hot environment under high engine speeds operating, and the safe and reliable work of energy subtracts
Few situation that short circuit is generated because of harness non-refractory.Meanwhile the utility model has the further advantage that
1, the conductive core that the utility model uses is formed by more thin aluminum-alloy wire bundle strand, compared to the copper conductor of same performance
Automotive wire bundle can reduce weight about 15%~25%, and cost can reduce about 30%~50%.So that cable not only soft matter
Gently, curvature is good, economical and practical；
2, the insulating layer of the utility model is poly- with using in the prior art using the flame-retardant organosilane cross-linked poly-ethylene extruded
The insulating layers such as vinyl chloride are compared, and anti-flammability, Environmental-protection comprehensive performance significantly improve；
3, the utility model sheath uses composite glass fiber silk, weaves after impregnating ptfe emulsion,
It can not only use under the high temperature conditions, and there is incombustibility, substantially increase its anti-flammability, highest is resistant to 200 DEG C of high temperature.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the top view of the utility model.
Wherein: 1, conductive core；2, insulating layer；3, sheath.
Specific embodiment
With reference to the accompanying drawing, illustrate specific embodiment of the present utility model.
As depicted in figs. 1 and 2, the soft aluminium alloy fire-resistant wire of a kind of vehicle of the present embodiment, including at least one is by leading
The outside of the cable core that battery core 1, insulating layer 2 are constituted, cable core uses woven protective layer 3；Made of conductive core 1 is drawn as 8 line aluminium alloys
Diameter is that 0.25mm~0.5mm aluminum-alloy wire bundle strand forms.
Conductor wire core 1 is by thin aluminum-alloy wire, after bundle strand, puts into annealing furnace the annealing by following technique: 1~2
Hour is heated up to 300~350 DEG C, then keeps the temperature 4~5 hours, and such conductive material elongation has good up to 15% or more
Flexibility, alternating bending frequency >=25 time.
Insulating layer 2 uses flame-retardant organosilane cross-linked poly-ethylene material, is coated to outside conductive core by extrusion process.
Sheath 3, the weaving of use are shining compound glass fiber after impregnating ptfe emulsion
It is dry, using the weaving of 8 ingots, 16 ingots or 24 ingots, weave.
The utility model generates in hot environment under high engine speeds operating, and the safe and reliable work of energy is reduced because of line
Beam non-refractory and generate short circuit situation.
Above description is the explanation to the utility model, is not the restriction to utility model, defined by the utility model
Range is within the protection scope of the utility model referring to claim, can make any type of modification.
