Abstract
The invention provides a coaxial signal cable for an aerial fuel gauge, belonging to the coaxial signal cables. The invention mainly solves the technical problem that the coaxial signal cables for the existing fuel capacity systems have poor electromagnetic compatibility. The coaxial signal cable is characterized in that the coaxial signal cable comprises a conductor (1), insulating layers (2), a shielding layer (3) and a sheath layer (4); the cable takes the conductor (1) as the center; more than one insulating layer (2) is arranged around the conductor (1); the shielding layer (3) and the sheath layer (4) are arranged outside the insulating layers (2) from inside to outside in sequence; the insulating layers (2) are wound by high temperature resistant polytetrafluoroethene film strips; and the shielding layer (3) is formed by braiding silver-plated copper wires. The coaxial signal cable has excellent wear resistance, high/low temperature resistance, flame retardance and the like, has good electromagnetic compatibility and strong interference resistance and is mainly used for the aircraft fuel capacity control systems.
Description
Technical field
The present invention relates to a kind of electric wire, particularly a kind of production domesticization Electro Magnetic Compatibility and anti-interference coax signal cable that can be used for aircraft fuel oil oil mass system.
Background technology
Fuel oil is the blood of aircraft engine, grasp at any time its storage capacity what and distribute, for estimating flight, the different distributions of fuel oil may cause that the center of gravity variation of aircraft etc. is all significant.Order situation of difficult at coax signal cable made in CCCP, and under the situation that existing homemade this cable can not directly replace, carry out this cable production domesticization research, to aircraft fuel oil oil mass system coax signal cable production domesticization electromagnetic compatibility Journal of Sex Research, very important with plaing a part.
Summary of the invention
At the present domestic cable that adheres to specification fully that still do not have, and foreign technology is also underground and be subjected to strict blockade, for overcoming above-mentioned existing in prior technology weak point, antijamming capability and Electro Magnetic Compatibility are met specification requirement to satisfy the aircraft fuel oil control system.The purpose of this invention is to provide a kind of aero oil scale coax signal cable that has performance such as anti-interference, fire-retardant, wear-resisting, high temperature resistant, cold-resistant and have good Electro Magnetic Compatibility.
The technical solution adopted for the present invention to solve the technical problems is: it comprises conductor 1, insulating barrier 2, screen 3 and restrictive coating 4, and it is the center with conductor 1, around conductor 1 insulating barrier 2 more than 1 layer is set; Set gradually screen 3 and restrictive coating 4 from the inside to the outside at insulating barrier 2 skins, described insulating barrier 2 is by wrapped the forming of resistant to elevated temperatures polytetrafluoroethylene film band, and described screen 3 adopts the silver-gilt copper wire braiding to form.
Described conductor 1 is to adopt soft stranded the forming and single-core line of silver-coated copper wire, makes insulating barrier with the wrapped multilayer of high temperature resistant PTFE film material and form insulated wire cores outside conductor 1.Also can adopt soft stranded the forming and single-core line of silver-coated copper wire, again by the many stranded multicore cables that form of single-core line, and with thermostable fluorine plastic material lapped insulation layer formation insulated wire cores.
Described restrictive coating 4 is to form by resistant to elevated temperatures polytetrafluoroethylene film is wrapped; Or extrude by resistant to elevated temperatures insulation fluoroplastics and to form; Or by resistant to elevated temperatures polytetrafluoroethylene film wrapped after, adopt resistant to elevated temperatures insulation fluoroplastics to extrude again and form.
The present invention mainly is in order to solve technical problems such as having oil mass system coax signal cable Electro Magnetic Compatibility difference now, it has premium properties such as wear-resisting, high temperature resistant, low temperature resistant, fire-retardant, and its Electro Magnetic Compatibility is good, strong interference immunity, and it mainly is to be used for aircraft fuel oil fuel-flow control system.
Description of drawings
Fig. 1 is a structural representation of the present invention
Among the figure: 1-conductor, 2-insulating barrier, 3-screen, 4-restrictive coating.
Embodiment
Below in conjunction with drawings and Examples the present invention is described in further details.
By adopting soft silver-plated copper conductor, the resistance to corrosion of conductor is strong, and welding effect is good, and flexibility is good, is convenient to install.Its insulating barrier adopts the wrapped one-tenth insulating barrier of high temperature resistant PTFE film material, and dielectric coefficient is less, and high and low temperature resistance is good, chemical resistance, performance such as flexibility is good.Also can be by insulating barrier be increased thickness, and outside diameter control makes its capacitance profile parameter of cable reach instructions for use in certain scope.By adopting the silver-gilt copper wire woven shield, have higher shielding braid density, make whole cable have good shielding properties, blocking-up is disturbed fully.Its sheath material can adopt the wrapped fluoroplastic insulation material thin with extruding one deck of polytetrafluoroethylene film, make sheath more soft, and external diameter is in setting.Thereby make that cable is more wear-resisting, oil resistant, corrosion-resistant, high temperature resistant, low temperature resistant, environmental protection, performance such as fire-retardant.It mainly is to be used for aircraft fuel oil fuel-flow control system, its Electro Magnetic Compatibility and anti-interference strong.
Embodiment 2, and conductor of the present invention also can adopt soft stranded the forming and single-core line of silver-coated copper wire, again by the many stranded multicore cables that form of single-core line, and with thermostable fluorine plastic material lapped insulation layer formation insulated wire cores.Consult Fig. 1, all the other are with embodiment 1.
Embodiment 3, and restrictive coating 4 of the present invention can form by resistant to elevated temperatures polytetrafluoroethylene film is wrapped; Consult Fig. 1, all the other are with above-mentioned embodiment.
Embodiment 5, after restrictive coating 4 of the present invention is can be by resistant to elevated temperatures polytetrafluoroethylene film wrapped, adopts resistant to elevated temperatures insulation fluoroplastics to extrude again and form.As adopt the high temperature resistant polytetrafluoroethylene film band of wrapped one deck and extrude the thin thermostable fluorine plastic insulation material of one deck, make it to form the cable of tight softness.Consult Fig. 1, all the other are with above-mentioned embodiment.
