A kind of Aero-Space alloy conductor cable
Technical field:
The utility model relates to cable process technology, relates in particular to a kind of Aero-Space alloy conductor cable.
Background technology:
The cable of using at aerospace field at present not only needs it to have good conductivity, insulation property and mechanical performance, to guarantee aerospace equipment normally operation in particular surroundings, simultaneously to the requirement of its weight also in continuous raising.
The bad mechanical property of original Aero-Space cable, insulation property do not reach demand, and overall weight is relatively large, and effect is relatively poor in actual use, can not satisfy the demands.
Utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of Aero-Space alloy conductor cable, simple and reasonable, can effectively improve electric conductivity and the mechanical performance of cable, weight is less simultaneously, and warp resistance performance improves, practical.
The technical solution of the utility model is as follows:
Aero-Space alloy conductor cable; comprise many conductors; it is characterized in that: many described conductors adopt magnadure tow strand to form; many conductors are coated with respectively fluoroplastic insulation layer outward and form insulated wire cores; insulated wire cores surrounds annular extrusion moulding and in elastic protective layer, forms cable core; elastic protective layer between cable core center and adjacent insulated wire cores is respectively equipped with cross section for the tension band of " * " shape tensile core and arc; cable core outside is coated with aluminium foil lapping layer, and aluminium foil lapping layer outside is provided with foamed plastic layer, fluoroplastics external sheath layer successively.
Described is characterized in that: described elastic protective layer adopts ethylene propylene diene rubber extrusion moulding.
Described is characterized in that: the wrapped rate of putting up of described aluminium foil lapping layer is not less than 24%, and the thickness of aluminium foil is not less than 0.12mm.
The utility model has the advantages that:
The utility model structural design is novel; cable core is arranged in elastic protective layer; the tension band that is simultaneously provided with " * " shape tensile core and arc in elastic protective layer improves the mechanical performance of cable; elastic protective layer also can further promote the insulation property of cable; in addition; the overall weight of cable reduces, and is convenient to mounting and installation.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1:
Aero-Space alloy conductor cable; comprise many conductors 1; many conductors 1 adopt magnadure tow strand to form; the many outer fluoroplastic insulation layers 2 that are coated with respectively of conductor 1 form insulated wire cores; insulated wire cores surrounds annular extrusion moulding and form cable core in elastic protective layer 3; elastic protective layer 3 between cable core center and adjacent insulated wire cores is respectively equipped with cross section for the tension band 5 of " * " shape tensile core 4 and arc; cable core outside is coated with aluminium foil lapping layer 6, and aluminium foil lapping layer 6 outsides are provided with foamed plastic layer 7, fluoroplastics external sheath layer 8 successively.
Elastic protective layer 3 adopts ethylene propylene diene rubber extrusion moulding, strengthens the external force resistance flat ability of cable, also can further promote the insulation property of cable simultaneously.
The wrapped rate of putting up of aluminium foil lapping layer 6 is not less than 24%, and the thickness of aluminium foil is not less than 0.12mm, can resist extraneous electromagnetic interference.
