Abstract
An ignition coil comprises a shell in a cylinder shape and an iron core penetrating through the shell in an axial direction. A primary coil is arranged on the outer wall of the iron core in a winding mode. A framework is arranged on the outside of the primary coil and provided with a secondary coil in a winding mode. Baseboards are arranged at two ends of the shell, and paraffin wax is filled in gaps of inner cavities of the baseboards which are provided with low pressure wiring boards. A high pressure wiring board is arranged on the lateral wall of the shell. Two ends of the primary coil are respectively connected with two low pressure wiring boards. One end of the secondary coil is connected with the primary coil, and the other end of the secondary coil is connected with the high pressure wiring board. According to the ignition coil, power supply is switched on and off through the primary coil, extremely high pressure is sensed by the secondary coil, and therefore a spark plug is ignited. Energy obtained by the secondary coil is great, and energy conversion efficiency is high. The ignition coil had the advantages of being small in size, compact in structure, long in service life, widely suitable for an electronic ignition system and the like.
Description
Technical field
The utility model relates to a kind of ignition mechanism for motor car engine, specifically a kind of spark coil of spark plug.
Background technique
Why spark coil can become high voltage with low tension on the car, is that the turn ratio of primary air and secondary winding is large because the form identical with common transformer being arranged.But the spark coil working method is different with common transformer, and common transformer is continuous operation, and spark coil then is interrupter duty, and it carries out energy storage and exoergic according to the different rotating speed of motor repeatedly with different frequencies.When elementary coil switch power, produce a very strong magnetic field around the growth along with electric current, iron core has stored magnetic field energy; When switch gear disconnects the primary air circuit, decay rapidly in the magnetic field of primary air, and secondary winding will induce very high voltage.The magnetic field disappearance speed of primary air is faster, and the electric current that electric current disconnects moment is larger, and the turn ratio of two coils is larger, and then the voltage that induces of secondary winding is higher.Patent Office of the People's Republic of China is disclosed on October 17th, 2007, and the patent No. is " spark coil " of " ZL200710086239.5 ", and it comprises main coil, inferior coil, central core and outer core.Described outer core is positioned in the two radial outside of described main coil and described coil.Mounting structure, it is essentially cylindrical, has inner edge, via described inner edge described mounting structure is assembled on the described outer core.Connector shell has pilot hole, via described pilot hole described connector shell is assembled on the outer rim of described mounting structure.Described connector shell is connected with the axial end of described coiler part via described mounting structure.This spark coil comparatively speaking volume is larger, is unfavorable for installing.
The model utility content
The purpose of this utility model is for the defective of above-mentioned prior art and deficiency, for people provide a kind of volume little, and compact structure, the spark coil of long service life is used for plug ignition.
Technical solution adopted in the utility model is for achieving the above object: this spark coil comprises shell cylindraceous and axially is interspersed in the interior iron core of shell, described iron core outer wall has installed around primary air, arranged outside at primary air has skeleton, installed around secondary winding at skeleton, the two ends of described shell are provided with base plate, the gap in chamber is filled with paraffin in the enclosure, be separately installed with the low pressure wire board at two base plates, sidewall at shell is equipped with the high-voltage connection plate, the two ends of primary air link to each other with two low pressure wire boards respectively, one end of secondary winding is connected with primary air, and the other end links to each other with the high-voltage connection plate.
Described primary air adopts the enameled cable of 0.5-1 millimeter, twines the 200-500 circle; Described secondary winding adopts the enameled cable of 0.05-0.2 millimeter, twines the 15000-25000 circle.
Described low pressure wire board is fixed by hollow copper rivet and base plate, and the high-voltage connection plate is fixed by hollow copper rivet and shell.
Described iron core is coated with the end envelope at the two ends of exposing shell, this end envelope is epoxy resin.
The outside of described end envelope is set with paper sleeve.
The utility model is by primary air connection, deenergization, make secondary winding induce very high voltage, thereby can make plug ignition, the energy that its secondary winding obtains is large, effciency of energy transfer is high, and it is little to have a volume, compact structure, the advantage of long service life can be widely used in the electronic ignitin system.
