Embodiment
Fig. 1～Fig. 2 illustrates a kind of plug-in type automobile ignition coil iron core that the air gap magnetic links is set; Comprise the U sections core 1 and the 2nd U sections core 2 that form annular core through butt joint; The one U sections core 1 and the 2nd U sections core 2 one sides are for being fixedly connected end; Be provided with air gap between the opposite side end face, it is characterized in that in said air gap, inserting the polarity magnetic links 3 opposite with the iron core magnetizing direction.Above-mentioned magnetic links 3 adopts common magnet steel to get final product, like N30UH.The material of an above-mentioned U sections core and the 2nd U sections core is the grain oriented electrical steel with higher magnetic permcability.Adopted the 30Q130 grain oriented electrical steel in this example, iron core magnetic permeability μ is improved.
The fixed connection end that the fixed connection end of an above-mentioned U sections core 1 is provided with protruding stupefied 11, the two U sections cores 2 is provided with and inserts groove 21 through protruding stupefied 11 with interference fits with protruding stupefied 11 corresponding groove, 21, the one U sections cores 1 and the 2nd U sections core 2 and be mutually permanently connected.Adopt socket connection can save the adhering with epoxy resin operation, avoid the harm of epoxy resin adhesive, help health human body.
Fig. 3 adopts ignition coil structure sketch map of the present invention.Ignition coil mainly comprises annular core, the primary coil of being made up of a U sections core 1 and the 2nd U sections core 27, secondary coil 6, housing 9, low pressure input 4 that is connected with primary coil 7 and the high-voltage output end 8 that is connected with secondary coil 6.In the actual fabrication, annular core places housing, through encapsulated epoxy resin, magnetic links 3 is fixed in the air gap.
Operation principle of the present invention is: the basic structure of ignition coil is to constitute around being looped around annular core by two windings, and the winding that connects supply voltage is called primary coil, and the winding that produces output voltage is called secondary coil.The lead that two coil windings adopt is generally the oxygen-free cupreous that is coated with urea-formaldehyde plastics or nylon, and typical iron core is processed by the iron containing alloy of the high silicon content with high anti-annealing.ID Inductive Discharge needs a low-voltage (typical 6-12V) to be added to primary coil, passes through with electric current, set up magnetic field lentamente, and storage power is in iron core.But during deenergization voltage, fail rapidly in magnetic field, and energy is discharged into primary coil and secondary coil, because the secondary coil number of turn is greater than number of primary turns, the energy overwhelming majority that is stored in the iron core is transported to secondary coil, produces high voltage output.
In iron core air gap, insert the polarity magnetic links opposite with the iron core magnetizing direction; Actual is to add a bias magnetic field in the opposite direction of magnetizing direction; When magnetizing; To magnetize in the other direction to magnetic links, make iron core and magnetic links all obtain to magnetize, make limited iron core energy storage originally increase a part of magnetic energy extraly.
In addition, iron core has adopted grain oriented electrical steel in this example, iron core magnetic permeability μ is improved, according to formula L=μ * Ae * N
2/ Le (wherein: L is a winding inductance quantity, and Ae is the iron core cross-sectional area, and N is a coil turn, and Le is the length of magnetic path) and formula E=1/2 * LI
2(wherein: E is the energy that is input to coil, and L is the coil inductance value, and I is a coil current), the μ value improves, and the iron core energy storage increases, and the energy that is transported to secondary coil is improved, and high pressure output improves.
Moreover, according to dv=d Φ/dt (wherein: v is an output voltage, and Φ is a magnetic flux).Owing in the magnetic field of magnetizing, add the opposing magnetic field, when demagnetization, variation rate of magnetic flux is improved, thereby the output of secondary coil high pressure is improved.
In sum, in iron core air gap, set up magnetic links, and iron core employing grain oriented electrical steel material, the iron core energy storage is increased, the energy that is input to secondary coil is improved, the secondary coil output voltage is improved.
The above only is the preferred embodiments of the present invention, is not shape material of the present invention and structure are done any pro forma restriction.Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
