Abstract

The utility model discloses a high-voltage ignition wirecable for automobiles. The high-voltage ignition wirecable is composed of ignition wire cores 1, ignition wire cores 2, a steel wire armored layer, a polyethylene inner sheath and a ceramic fluorine rubber outer sheath, wherein the three ignition wire cores 1 are extruded in a shape like the Chinese character 'pin'; the ignition wire cores 2 are arranged in gaps between outer sides of every two adjacent ignition wire cores 1; a ground wire core is arranged among every two ignition wire cores 1 and one ignition wire core 2 which is correspondingly arranged on the outer side; a cable core is formed by extruding a water-blocking belt wrapping layer on the three ignition wire cores 1 and the ignition wire cores 2; a flame-retardant filling strip is arranged in a gap of the cable core; and the steel wire armored layer, the polyethylene inner sheath and the ceramic fluorine rubber outer sheath are sequentially covered on the water-blocking belt wrapping layer from inside to outside. The high-voltage ignition wirecable for automobiles adopts the 3+3 wire core symmetric structure, and has the advantages of stable current, high anti-interference performance, flame retardance, high temperature resistance, radiation resistance, and excellent mechanical properties.

Description

A kind of high-pressure car ignition wire cable

Technical field

The utility model relates to cable, relates 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.

Utility model content

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

Scheme of the present utility model 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 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.

The beneficial effects of the utility model: the utility model 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.
