Abstract

The invention discloses a vehicle high-pressure ignition cable which consists of ignition wire cores I, ignition wire cores II, a steel wire armored layer, a polyethylene inner sheath and a ceramic fluororubber outer sheath, wherein three ignition wire cores I are pressed and wrapped into a triangle; the ignition wire cores II are arranged in gaps between the outer sides of every two adjacent ignition wire cores I; a ground wire core is arranged between every two ignition wire cores I and the corresponding ignition wire core II at the outer sides; a water-resistant warping layer is pressed and wrapped on the three ignition wire cores I and the ignition wire cores II to form a cable core; gaps in the cable core are filled with flame-retardant filling strips; the water-resistant warping layer is sequentially covered by the steel wire armored layer, the polyester inner sheath and the ceramic fluororubber outer sheath from inside to outside. A ''three plus three'' cable symmetric structure is adopted by the invention, the current is stable, the disturbance resistance is strong, the functions of flame retardance, high-temperature resistance and radiation resistance are provided, and the mechanical performance is good.

Description

A kind of high-pressure car ignition wire cable

Technical field

The present invention relates to cable, relate in particular to a kind of high-pressure car ignition wire cable.

Background technology

High-pressure car ignition wire cable needs high temperature resistant-40 degree to+220 degree, high pressure 35KV; Core adopts silicone insulation, resistance stabilization, and electric conductivity is superior; Line body steel plate, useful life is more lasting.From internal structure, high-pressure ignition wire has single core, three cores, four-core, five cores point.Be that core body is more in principle, the less ignition intensity of resistance is higher, and price is also more expensive.But core body is too many, electric current is excessively strong, if do not adopt special packaging and shielding material, can produce electromagnetic interference makes vehicle audio and vehicle-mounted computer be subject to the interference of electromagnetism and cannot normally work, and firepower crosses and also easily cause by force the inadaptable of automobile engine, be subject to the interference of electromagnetism and the symptom such as cannot normally work thereby cause automobile to shake, reduce ignition coil and spark plug life, vehicle audio and vehicle-mounted computer.

Summary of the invention

According to above-mentioned situation, the object of the invention is to provide a kind of high-pressure car ignition wire cable.

The solution of the present invention is as follows: a kind of high-pressure car ignition wire cable, it is made up of igniting core one, igniting core two, wire armoring layer, polyethylene inner sheath and ceramic fluorubber oversheath, and described igniting core one ecto-entad extrudes successively silver-gilt copper wire flexible conductor by copper strips lapping layer, conductor shield, silicone rubber insulation layer and insulation screen and forms; Described igniting core two is from interior to forming to extruding successively silver-gilt copper wire flexible conductor by insulation screen and silicone rubber insulation layer; One one-tenth " product " font of described three igniting cores extrudes; Described igniting core two is arranged in the gap between every two adjacent igniting core one outsides; Between every two igniting cores one and the igniting core two in corresponding outside, be provided with a ground wire core; Waterstop lapping layer extrudes into cable core by three igniting cores one with igniting core two; In gap in described cable core, be provided with flame retardant filler strip; Described wire armoring layer, polyethylene inner sheath and ceramic fluorubber oversheath from inside to outside cover on waterstop lapping layer successively.

The silver-gilt copper wire flexible conductor of described igniting core one is to be stranded the forming of silver-gilt copper wire of 2.52 square millimeters by 10 cross-sectional areas.

The silver-gilt copper wire flexible conductor of described igniting core two is to be stranded the forming of silver-gilt copper wire of 0.65 square millimeter by 19 cross-sectional areas.

Beneficial effect of the present invention: the present invention adopts 3+3 core symmetrical structure, current stabilization, anti-interference strong, there is flame-resistant high-temperature-resistant, radiation-resistant effect, mechanical performance is good.

Brief description of the drawings
