Abstract
The utility model discloses an ignition coil of a DC24V power-supply system. The ignition coil comprises a primary winding, a secondary winding, an iron core, a high voltage connecting end, a low voltage connecting end and the static parameter of the ignition coil, wherein the primary resistance of the primary winding is 2.6 plus or minus 0.3 ohm, and the primary inductance thereof is 24 plus or minus 4.0mH; the primary resistance of the secondary winding is 13.5 plus or minus 1.4Kohm, and the primary inductance thereof is 50 plus or minus 7.5H; while increasing the coiling number of windings of the primary winding and improving the inductance of the primary winding, under the same ignition frequency, the system ensures the output voltage thereof to be consistent with that of the original system, and adapts to the requirements of new power-supply system DC24V.
Description
Technical field
The utility model relates to the car engine ignition device, promptly automobile-used spark coil.
Background technique
The power supply system of automobile is DC12V at present, because the increase of the power consumption of automobile, the DC12V system has been difficult to bear huge current load.Therefore, automobile power supply system is risen to DC24V become inexorable trend, automobile ignition coil also will improve thereupon, rises to DC24V by DC12V, to adapt to the needs of new system.
The model utility content
The purpose of this utility model is to provide DC24V power supply system spark coil, under identical spark rate, guarantees that the voltage of its output is consistent with original system.
Above-mentioned purpose is achieved through the following technical solutions:
DC24V power supply system spark coil, comprise elementary winding, secondary windings, iron core, high pressure connecting end and low pressure connecting end is characterized in that: the static parameter of spark coil, the elementary resistance of elementary winding: 2.6 ± 0.3 Ω, primary inductance: 24 ± 4.0 mH; Secondary windings, its secondary resistance: 13.5 ± 1.4 K Ω, secondary inductance: 50 ± 7.5 H.
The spark coil of said structure, it is the parameters of redesign elementary winding of spark coil and secondary windings, at the number of turns that increases elementary winding, improve the inductance value of elementary winding, under identical spark rate, the voltage that guarantees its output is consistent with original system, adapts to the needs of new power supply system DC24V.
