Abstract
The utility model discloses an aviation soft cable, wherein a conductor of the aviation soft cable is formed by stranding a plurality of nickel-plated fine wires; ceramic silicon rubber is extruded outside the conductor to form an insulating layer which forms an insulating wire core; an outer sheath layer which is formed by extruding the ceramic silicon rubber is arranged outside the insulating wire core; the conductor is selected as category 5 conductor which meets GB/T3956; the conductor is in a regular stranded structure; the stranding pitch is 10-16 times; the sectional area of the conductor is 0.5-2.5 mm<2>; and 2-10 insulating wire cores are arranged. The cable provided by the utility model has the comprehensive performance such as high/low temperature resistance, fire resistance, environmental friendliness, flame retardancy, no halogen, low smoke and softness, and can adapt to various different working environments.
Description
Technical field
The utility model relates to a kind of aviation flexible cable, 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 cube little, adapt to that all kinds of adverse circumstances, ampacity are 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 provides a kind of can possess high-low temperature resistant, 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: a kind of aviation flexible cable, its conductor is twisted into by many nickel plating filaments, the ceramic SiClx rubber of extruding forms insulating barrier formation insulated wire cores outside conductor, and the external sheath layer of ceramic silicon rubber extrusion modling is set outside insulated wire cores.
Described conductor is chosen as the 5th class conductor that meets GB/T3956.
Described conductor adopts regular lay configuration, and the twisted wire pitch is that the sectional area of described conductor is 0.5～2.5mm between 10-16 times
2
Described insulated wire cores is the 2-10 core.
The utility model beneficial effect:
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.
A kind of aviation flexible cable, its conductor 1 is twisted into by many nickel plating filaments, forms insulating barrier 2 at the ceramic SiClx rubber of conductor 1 outer extruding and consists of insulated wire cores, and the external sheath layer 3 of ceramic silicon rubber extrusion modling is set outside insulated wire cores.
Described conductor 1 is chosen as the 5th class conductor that meets GB/T3956.
Described conductor 1 adopts regular lay configuration, and the twisted wire pitch is that the sectional area of described conductor is 0.5～2.5mm between 10-16 times
2
Described insulated wire cores is the 2-10 core.
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.
