Abstract

The utility model discloses an aviation cable. A conductor is formed by a plurality of nickel plating soft copper monofilaments. A ceramic silicone rubber is extruded outside the conductor so as to form an insulating layer and an insulation wire core is formed. The three insulation wire cores are combined and then a metal shielding layer wraps the three insulation wire cores so as to form a shielding wire core. The three shielding wire cores are combined and then a polyurethane belting layer wraps the three shielding wire cores. A silver-plated copper wire shielding layer, a half metal armoring layer and an outer sheath layer which is formed through carrying out extrusion molding on the ceramic silicone rubber are successively arranged outside the polyurethane belting layer. Three nylon wire cores are arranged among the three shielding wire cores. An insulation wire core II is arranged at a cable center. A metal shielding layer II wraps two guide cores so as to form the insulation wire core II. A ceramic silicone rubber insulating layer II wraps the conductor so as to form the guide core. The cable possesses the advantages that the structure is simple; heatproof and low-temperature-resistant performance is possessed; inflaming-retarding, halogen-free, non-poisonous and low-smoke properties are achieved and so on.

Description

A kind of Aviation cable

technical field

The utility model relates to a kind of Aviation cable, belongs to technical field of electric wires and cables.

background technology

Aviation cable is the nervous system of aircraft, is connecting each systems such as aircraft is electric, avionics, fire control, manipulation, for the each parts of aircraft provide electrical source of power, control signal and data message.Be subject to the restriction in airframe space, cable system wiring generally all concentrates in narrow and small machine wall, in aircraft machine wall, almost spreads all over wire, and therefore Aviation cable system requirements is highly reliable, high integrated, high light; Because wire is of a great variety, all kinds of power lines, low-and high-frequency holding wire, data wire are mixed in together, length can reach several hundred kilometers, electric circumstance is very complicated, thereby its incipient fault is increased, and many air crashes are all directly or indirectly relevant with cable system fault with aircraft fault, therefore, " health " of Aviation cable is the important leverage of aircraft safety operation, and cable security problem is particularly important.

utility model content

It is a kind of simple in structure, heat-resisting, low temperature resistant that the utility model provides, and has the Aviation cable of the features such as fire-retardant, Halogen, nontoxic, low cigarette.

Scheme of the present utility model is as follows: a kind of Aviation cable, and conductor is made up of many nickel plating soft copper monofilament, and outside described conductor, the ceramic SiClx rubber of extruding forms insulating barrier formation insulated wire cores, and after three insulated wire cores combinations, wrapped metal screen layers form shielding core; Wrapped polyurethane belting layer after the combination of three shielding cores, described polyurethane belting layer sets gradually silver-gilt copper wire screen, metal armour half dress layer outward and adopts the jacket layer of ceramic silicon rubber extrusion modling; Between three described shielding cores, three nylon cores are also set, cable center also arranges an insulated wire cores II, described insulated wire cores II is led the wrapped metal screen layer II of core by two and is formed, and the described core of leading is made up of the outer wrapped ceramic silicone rubber insulation layer II of conductor.

Further, described conductor is chosen as the 5th class conductor that meets GB/T3956, and the sectional area of described conductor is 1～3mm ².

Further, described conductor is chosen as the 5th class conductor that meets GB/T3956, and the sectional area of described conductor is 1～3mm ².Described conductor adopts regular lay configuration, and twisted wire pitch is between 10-12 times.

The conductor that the utility model adopts nickel plating soft copper monofilament to form, can prevent the aging catalytic action of copper conductor to insulating barrier, effectively to ensure the useful life of insulating barrier.Meanwhile, also can effectively prevent the oxidation of soft copper monofilament conductor itself at the plating nickel on surface of soft copper monofilament, increase the security reliability in use procedure.In the utility model, insulating material and sheath material, all taking ceramic silicon rubber as material, have the chemical resistance of wide range, have excellent heat-resisting and resistance to low temperature, and heat-resisting peak reaches 220 DEG C, and continuing serviceability temperature is-70 DEG C～200 DEG C; Also possess superior fire-retardant, Halogen, nontoxic, low cigarette feature simultaneously, meet the ROHS of European Union instruction, reach ZA1 level security standard.

brief description of the 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 cable, conductor is made up of many nickel plating soft copper monofilament, forms insulating barrier 2 form insulated wire cores at the ceramic SiClx rubber of the outer extruding of described conductor 1, and after three insulated wire cores combinations, wrapped metal screen layer 3 forms shielding core; Wrapped polyurethane belting layer 4 after the combination of three shielding cores, the outer jacket layer 7 that sets gradually silver-gilt copper wire screen 5, metal armour half dress layer 6 and adopt the extrusion modling of ceramic silicon rubber of described polyurethane belting layer 4; Between three described shielding cores, three nylon cores 8 are also set, cable center also arranges an insulated wire cores II 9, described insulated wire cores II 9 is led the wrapped metal screen layer II of core by two and is formed, and the described core of leading is made up of the outer wrapped ceramic silicone rubber insulation layer II of conductor.

Described conductor 1 is chosen as the 5th class conductor that meets GB/T3956, and the sectional area of described conductor 1 is 1～3mm ².Described conductor 1 is chosen as the 5th class conductor that meets GB/T3956, and the sectional area of described conductor 1 is 1～3mm ².Described conductor 1 adopts regular lay configuration, and twisted wire pitch is between 10-12 times.

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 amendment; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
