Abstract

Voltage ignition wire of high of the present invention is based on high-tech electronic equipment and uses in automobile and produce under all the more strict background of increasingly extensive, toxic emission environmental requirement.The frequency electromagnetic waves that the automotive ignition electric wire is produced when high-tension ignition is interfered to the electronic equipment in the car, even can't operate as normal.Present method is to adopt the damp type conductor wire core, has the resistance value of 1～5K Ω/m, and this makes moderate progress to the interference strength that reduces frequency electromagnetic waves, but simultaneously the cylinder firings energy is weakened, and causes the automobile actuating force to reduce.The present invention all has significant improvement to the structure of high-voltage ignition for automobile electric wire and the performance of High-Voltage Insulation rubber, requires to reach the actuating force that has both improved automobile, more effectively reduces the interference of frequency electromagnetic waves to the car inner electronic equipment again.

Description

High-voltage ignition wire of high-energy and strong-shielding automotive engine

1. consider that the electronic equipment of using in the current automobile is increasing, more and more tighter to its environment for use requirement, the interference of the frequency electromagnetic waves that is produced when therefore being necessary further to reduce the work of high-voltage ignition for automobile electric wire.The present invention is outside 1000～1200 Ω/m winding type damping conductor wire core adopting resistance, increases the magnetic field metal screen layer of one deck Copper Foil or aluminium foil again on wire structure.

The frequency electromagnetic waves that is produced during voltage ignition wire of high work can produce eddy current loss, boundary reflection and reverse electromagnetic field on the metal screen layer of magnetic field.These electromagnetism physical actions consume all for the energy of high-frequency electromagnetic disturbing wave to some extent, thereby have played certain magnetic field shielding effect.The present invention stacks up damping resistance and the effect of metallic magnetic field shield layer, thereby obtains better anti-frequency electromagnetic waves interference function.

2. in design of the present invention, adopt the raising ignition voltage to remedy the reduction that makes ignition energy because of damping resistance.The ignition voltage that improves electric wire must be a prerequisite with the proof voltage intensity that improves the High-Voltage Insulation rubber.Trample evidence factually, adopt ethylene propylene diene rubber 60 weight portions and LDPE 40 weight portions to carry out blend, under well-designed prescription and manufacturing condition, the proof voltage intensity of the High-Voltage Insulation rubber that it makes, comparable common Ethylene Propylene Terpolymer insulation rubber exceeds more than 80%.This provides practical assurance for the operating voltage that improves ignition wire.

3. carbon fibre is a kind of new material, and its mechanical strength can be high temperature resistant greater than ordinary steel wire, has the semiconductive characteristic.Braiding one deck carbon fiber layer on the insulating barrier of voltage ignition wire of high, this is equivalent to increase one deck High-Voltage Insulation outer shielding layer on high-voltage insulation layer, and is very favourable to the distribution that improves high voltage electric field, thereby can improve the level of the withstand voltage test of electric wire.Simultaneously, the carbon fibre braid has also been strengthened the structure steadiness of high-voltage insulation layer, and this can significantly improve the level of the every performance test of electric wire finished product.

4. when extruding the high-temperature-resisting silicon rubber outer jacket, Copper Foil or aluminium foil are passed through special-purpose mould, metal forming is wrapped on the carbon fibre braid so that the mode of folding is vertical, make the magnetic field shielding layer that forms one deck base closed, but also can adopt around-packing technology that Copper Foil or aluminium foil is wrapped on the carbon fibre braid.

5. when high-voltage ignition for automobile electric wire of the present invention uses, at the same end of electric wire, respectively extract carbon fibre braid and metal screen layer out certain-length, and it tightly is screwed in together, and then it is connected on the automobile grounded metal body securely.

6. the visible Figure of description of the structural representation of voltage ignition wire of high of the present invention.

Claims

1. the high-voltage insulation layer of voltage ignition wire of high through special technology blend, and adds the necessary various compounding ingredients of hard rubber by ethylene-propylene rubber and vinyon.

2. the carbon fibre braid is arranged in the structure of voltage ignition wire of high.

3. in the structure of voltage ignition wire of high, have with Copper Foil or aluminium foil and make, at the magnetic field shielding layer of high-frequency electromagnetic wave interference.
