Description

Sparking plug to ignition cable of car}

The present invention relates to an ignition cable for spark plugs of various automobiles using gasoline and LPG fuel. In particular, the high voltage generated from the ignition coil located between the battery and the spark plug of the engine is used as the center electrode of the distributor and at the side electrodes of the distributor. For spark plugs in vehicles that supply sufficient high voltage to the engine's spark plugs to enhance the engine's explosive power and promote complete combustion, thereby improving the output of the vehicle and minimizing the generation of high-frequency noise generated during ignition. It relates to an ignition cable.

In general, the ignition device of a vehicle has a high voltage of about 20,00 V or more generated from an ignition coil located between an engine and a battery, and a high voltage current supplied to a plurality of spark plugs mounted inside the engine through a distributor and an ignition cable. The moment is short (short), the spark generated at this time is the fuel compressed in the cylinder is ignited and exploded to generate the output of the engine.

At the moment when a high voltage is shorted and spark is generated, a large amount of radiation noise is generated, which is reversed through the ignition cable as opposed to the direction of current supply, and is instantaneous in the ignition cable from the distributor to the spark plug. As a large amount of high-frequency noise is emitted, it affects various electronic products, electronic control unit (ECU), communication equipment, etc. installed in and around the engine room, and paralyzes the function instantly, causing malfunction. It is pointed out as one of the very high cause of the occurrence.

The general configuration of the ignition cable, which acts as a medium for emitting high frequency noise, is to place a core conductor consisting of a few strands of copper wire coated with tin or lead, centered on the outer peripheral surface, After securing the insulating layer and coating it with vinyl or silicon on it, and the insulating material on the conductive layer coated with fine carbon powder on the core conductor made of fiber yarn having high tensile strength such as glass fiber or aramid fiber. By directly coating rubber with a resistivity of about 10 ₁₅ Ω.㎝ to act as an outer surface of the wire, or by coating a conductive layer on the core conductor with an insulator on it and applying force to the wire For braiding the glass fiber or covering the outer surface of the wire, or after applying the coating to the core conductor with a conductive layer The conductive layer is wound with a nickel-chromium alloy wire having a diameter of about 0.04 to 0.07 mm so that the entire outer diameter thereof is about 1 to 4 mm and a resistance of 16 kW / m. The insulation is coated and the glass fiber is braided or braided. After that, the outer surface of the electric wire is coated.

The knitted glass fiber layer 1c is formed, and the outer skin layer 1d of the rubber material is finally formed on the outer surface of the glass fiber layer 1c.

Both ends of the ignition cable 1 are formed with a distribution cord cap 2 and a plug cap 3 having terminals having corresponding shapes therein so as to be closely connected to the distributor and the spark plug.

Therefore, the high-voltage cable for automobile spark plugs (Application No. 99-21234), which was devised to solve the conventional problems of the present applicant and jointly filed with the Korean Intellectual Property Office, has a spark plug coupling pipe and a distributor on both sides of a silicone rubber coated conductor. In a high-voltage cable for a conventional automotive spark plug in which a coupling tube is coupled, the center electrode constituting the conductor is composed of a plurality of copper wires and is lead-plated on the outer surface thereof.

However, high-frequency noise is generated instantaneously in the high-voltage cable that is the current supply line from the distributor to the spark plug, and the high-voltage cable acts as a high-frequency noise medium as it is transmitted through the ignition cable. (ECU) and electronic products, there is a problem that causes a sudden start or malfunction of the vehicle by impairing the wireless device.

Therefore, the present invention has been devised to solve such a fundamental problem of the prior art, and its purpose is to provide a high voltage generated by an ignition coil located between a battery and an ignition plug of an engine as a distributor center electrode and at the side electrode of the distributor. To supply sufficient high voltage to the engine to enhance the explosion power of the engine and to promote complete combustion, thereby improving the output of the vehicle and minimizing the generation of high frequency noise generated during ignition. And to provide an ignition cable for a vehicle's spark plug to prevent the electronic products, wireless devices and the like to cause a sudden start or malfunction of the vehicle.
