Abstract
The utility model discloses an environment-friendly high-temperature-resistant and fire-resistant flexible wire used in aviation. The conductor of the flexible wire is formed by concentrically twisting multiple nickel-plated soft copper single-core threads. A ceramic silicon rubber insulating layer is extruded on the outer side of the conductor to form an insulating wire core. An outer cover layer which is formed by extruding ceramic silicon rubber is arranged on outer side of the insulating wire core. The environment-friendly high-temperature-resistant and fire-resistant flexible wire used in aviation has combination properties of high temperature and low temperature resistance, fire resistance, environment friendliness, flame retardation, halogen freeness, low smoke, flame retardation and flexibility and is capable of adapting to various different work environments.
Description
Technical field
The utility model relates to a kind of aviation flexible cable, relates in particular to a kind of high temperature resistant fire-resistant environmental protection cable for aviation, belongs to technical field of electric wires and cables.
Background technology
Aerospace equipment has the requirements such as volume is little, lightweight along with the raising requirement of equipment performance to special installation.As spacecraft electrical installation, instrument and meter connecting line, want that cube is little, to adapt to all kinds of adverse circumstances, ampacity large and to bear overload capacity strong, and require cable to have good mechanical and physical performance, electric property and lay conveniently, that cable should have is high temperature resistant, fire-resistant, environmental protection, the characteristic such as fire-retardant, soft, and safety guarantee is had relatively high expectations.But existing normal cable can not satisfy this requirement.
The utility model content
The utility model is for avoiding the existing weak point of above-mentioned prior art, provide a kind of and can possess anti-high/low temperature, fire-resistant, environmental protection, fire-retardant, Halogen, low cigarette, the combination property such as fire-retardant and soft, can adapt to a kind of aviation flexible cable of multiple different operational environment.
Scheme of the present utility model is as follows: the fire-resistant aviation cord of a kind of environment-friendly type thermostable, conductor is formed by the many concentric skeins of nickel plating soft copper monofilament, skin at described conductor pushes ceramic SiClx rubber insulation formation insulated wire cores, the outer jacket layer that arranges by the extrusion modling of ceramic silicon rubber of described insulated wire cores.
Described conductor meets the 5th class conductor requirement of GB/T 3956.
Described conductor adopts concentric regular skein structure, and pitch is between 10-16 times.
The sectional area of described conductor is 0.5～6mm
2
The beneficial effects of the utility model:
1, the utility model adopts the many conductors that nickel plating soft copper monofilament is twisted into, and can effectively prevent copper conductor to the aging catalytic action of insulating barrier, to guarantee the useful life of insulating barrier.Simultaneously, copper wire plating nickel on surface, silver or zinc-platedly also have an oxidation that prevents conductor itself have improved the flexibility of conductor, increase the security reliability in the use procedure.
2, in the utility model insulating material and fire-resistant and sheath material all to adopt ceramic silicon rubber be material, have heat resistance and fire-resistant, the softness of wide range.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The fire-resistant aviation cord of a kind of environment-friendly type thermostable, conductor 1 is formed by the many concentric skeins of nickel plating soft copper monofilament, skin at described conductor 1 pushes ceramic SiClx rubber insulation 2 formation insulated wire cores, the outer jacket layer 3 that arranges by the extrusion modling of ceramic silicon rubber of described insulated wire cores.
In the implementation, conductor 1 is chosen as the 5th class conductor that meets GB/T3956; Conductor 1 adopts regular lay configuration, and the twisted wire pitch is between 10-16 times, has preferably flexibility and surperficial rounding property to guarantee conductor, and insulating barrier is easily peeled off; The sectional area of conductor 1 is 0.5～4mm
2It is the 2-10 core that insulated wire cores is set.
Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and modification; when its function that produces does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
