Description
Technical field
The present invention relates to a kind of ignition coils.
Background technology
In automotive engine ignition system, ignition coil is that a kind of air in ignition engine cylinder and fuel oil are mixed
Close the execution unit that object provides ignition energy.It is a kind of special burst booster based on electromagnetic induction principle, it is by 8-16V
Low-voltage be allowed to the secondary voltage for generating 20-40KV by setpoint frequency break-make electric spark generated by spark plug.
Invention content
To overcome the above disadvantages, the object of the present invention is to provide a kind of ignition coils of brand new.
In order to achieve the above object, the technical solution adopted in the present invention is：A kind of ignition coil, including shell, magnetism
Inner core, and magnetic outer core, the magnetic core periphery are provided with primary coil and secondary coil, the primary coil and
Power supply is connected, and the secondary coil is connected with high-pressure side, and the magnetic core and magnetic outer core are respectively by multi-disc silicon
Steel disc tinertoy is constituted, and is coated with electric conductive dustproof coating in the laminate surface of the magnetic core and magnetic outer core, described leads
Electric rust-proof coating covers the stacking end face of tinertoy to form flat surfaces.
As further improvement of the invention, the magnetic core, primary coil and secondary coil are fixed by resin
In enclosure interior.
As further improvement of the invention, the outer core of magnetism is integral with shell injection molding and is placed in enclosure interior.
As further improvement of the invention, electric conductive dustproof coating is also sprayed on the outer surface of the outer core of magnetism.
As further improvement of the invention, the surface spraying of magnetism outer core towards the secondary coil has electric conductive dustproof
Coating, the electric conductive dustproof coating towards the position of secondary coil be smooth surface.
As a result of above technical scheme, to be effectively reduced shape of the mouth as one speaks iron core inner surface in operating conditions because of iron core
Tinertoy out-of-flatness and the wedge angle electric field concentration phenomenon generated, ignition coil of the invention can improve ignition coil voltage endurance capability,
Ambient operating temperature and endurance life.
Description of the drawings
Attached drawing 1 is the cross-sectional structural schematic diagram according to the ignition coil of the present invention；
Attached drawing 2 is the vertical profile structural schematic diagram according to the ignition coil of the present invention；
Attached drawing 3 describes the outer iron core according to the present invention for being coated with electric conductive dustproof coating；
Attached drawing 4 describes the operation principle of the present invention.
Specific implementation mode
The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
Shown in attached drawing 1 and attached drawing 2, a kind of ignition coil, including shell 7 and be fixed in shell 7 by resin
Portion's magnetic core 1, primary coil 3 and secondary coil 5.
1 periphery of magnetic core is provided with primary skeleton 2, and have mercy on is formed with primary coil 3 above, is provided with outside primary coil 3
Secondary framework 4,4 Shangrao of secondary framework are formed with secondary coil 5, primary coil 3 is connected with power supply, usually vehicular power-bottle
12V low-voltage outputs, secondary coil 5 are connected with high-pressure side, specially spark plug.Magnetic outer core 6 and shell injection molding are integral
And it is placed in enclosure interior, constituting flux path prevents magnetic flux from leaking.
As shown in Fig. 4, magnetic core 1 and magnetic outer core 6 are made of multi-disc silicon steel sheet tinertoy respectively, 1 He of magnetic core
Be provided with electric conductive dustproof coating 8 on the stacking end face of magnetic outer core 6, electric conductive dustproof coating 8 stacking end face is covered to be formed it is flat
The dislocation generated between silicon steel sheet A and silicon steel sheet B in surface, such as figure is all covered by electric conductive dustproof sprayed coating and surface light
It is sliding, prevent that iron core tinertoy injustice generates wedge angle/electric field concentration effect, principle is on stacking end face since there are multiple points
Angle will generate the adverse consequences of point discharge when electric field reaches a certain level, and cause the damage of product, when the flat table of formation
Just this effect is eliminated behind face.
In one embodiment of the invention, the surface spraying of magnetic outer core 6 towards secondary coil 5 has electric conductive dustproof coating
8, electric conductive dustproof coating 8 towards the position of secondary coil 5 be smooth surface, as shown in Fig. 3, on the outer surface of magnetic outer core 6
Also spraying electric conductive dustproof coating 8.
In another embodiment of the present invention, it is also equipped with electric conductive dustproof coating 8 on the outer surface of shell 7, to have
Effect ground reduces the electric field concentration phenomenon that shape of the mouth as one speaks iron core inner surface is generated because iron core tinertoy is uneven in operating conditions, of the invention
Ignition coil can improve ignition coil voltage endurance capability, ambient operating temperature and endurance life.
The technical concepts and features of embodiment of above only to illustrate the invention, its object is to allow be familiar with technique
People understands present disclosure and is implemented, and it is not intended to limit the scope of the present invention, all according to spirit of that invention
The equivalent change or modification that essence is done should all cover within the scope of the present invention.
