Description
Technical field
The present invention relates to a kind of ignition coil.
Background technology
In automotive engine ignition system, ignition coil is a kind of mixed for the air in ignition engine cylinder and fuel oil
Compound provides the execution unit of ignition energy.It is a kind of special burst booster based on electromagnetic induction principle, and it is by 8-16V
Low-voltage be allowed to the secondary voltage producing 20-40KV by setpoint frequency break-make and produce electric spark by spark plug.
Summary of the invention
In order to overcome disadvantages mentioned above, it is an object of the invention to provide the ignition coil of a kind 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 housing, magnetic
Inner core, and the outer core of magnetic, described magnetic core periphery is provided with primary coil and secondary coil, described primary coil with
Power supply is connected, and described secondary coil is connected with high-pressure side, and described magnetic core and the outer core of magnetic are respectively by multi-disc silicon
Steel disc is folded riveting and is constituted, and the laminate surface of described magnetic core and the outer core of magnetic is coated with electric conductive dustproof coating, and described leads
The stacking end face of folded riveting is covered and forms flat surfaces by electricity antirust coat.
Further improving as the present invention, described magnetic core, primary coil and secondary coil are fixed by resin
In enclosure interior.
Further improving as the present invention, the outer core of described magnetic is molded into one with shell and is placed in enclosure interior.
Further improve as the present invention, the outer surface of the outer core of described magnetic also sprays electric conductive dustproof coating.
Further improving as the present invention, the outer core of described magnetic has electric conductive dustproof towards the surface spraying of secondary coil
Coating, described electric conductive dustproof coating is smooth surface towards the position of secondary coil.
Owing to have employed above technical scheme, thus it is effectively reduced shape of the mouth as one speaks iron core inner surface in operating conditions because of iron core
The wedge angle electric field concentration phenomenon folding riveting out-of-flatness and produce, the ignition coil of the present invention can improve ignition coil voltage endurance capability,
Ambient operating temperature and endurance life.
Accompanying drawing explanation
Accompanying drawing 1 is the cross-sectional structural representation of the ignition coil according to the present invention;
Accompanying drawing 2 is the vertical profile structural representation of the ignition coil according to the present invention;
Accompanying drawing 3 describes the outer iron core being coated with electric conductive dustproof coating according to the present invention;
Accompanying drawing 4 describes the operation principle of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
See shown in accompanying drawing 1 and accompanying drawing 2, a kind of ignition coil, is fixed in housing 7 including housing 7 and by resin
Portion's magnetic core 1, primary coil 3 and secondary coil 5.
Magnetic core 1 periphery is provided with primary skeleton 2, the above rich primary coil 3 that is shaped with, and primary coil 3 outside is provided with
Secondary framework 4, secondary framework 4 Shangrao is shaped with secondary coil 5, primary coil 3 is connected with power supply, usually vehicular power-bottle
12V low-voltage output, secondary coil 5 is connected with high-pressure side, specially spark plug.The outer core 6 of magnetic is molded into one with shell
And it is placed in enclosure interior, constitute flux path and prevent magnetic flux from leaking.
As shown in Figure 4, magnetic core 1 and the outer core 6 of magnetic are made up of multi-disc silicon steel sheet stack riveting respectively, magnetic core 1 He
Being provided with electric conductive dustproof coating 8 on the stacking end face of the outer core 6 of magnetic, it is smooth that stacking end face is covered formation by electric conductive dustproof coating 8
The dislocation produced between stalloy A and stalloy B in surface, such as figure is all covered and surface light by electric conductive dustproof sprayed coating
Sliding, prevent that iron core is folded riveting injustice and produced wedge angle/electric field concentration effect, its principle is owing to there is multiple point on stacking end face
Angle, will produce the adverse consequences of point discharge when electric field reaches to a certain degree, causes the damage of product, when forming smooth table
Just this effect is eliminated behind face.
In one embodiment of the invention, the outer core 6 of magnetic has electric conductive dustproof coating towards the surface spraying of secondary coil 5
8, electric conductive dustproof coating 8 is smooth surface towards the position of secondary coil 5, as shown in Figure 3, on the outer surface of the outer core 6 of magnetic
Also spraying electric conductive dustproof coating 8.
In another embodiment of the present invention, the outer surface of housing 7 is also equipped with electric conductive dustproof coating 8, thus has
Effect ground reduces the electric field concentration phenomenon that shape of the mouth as one speaks iron core inner surface produces in operating conditions because iron core folds riveting injustice, the present invention's
Ignition coil can improve ignition coil voltage endurance capability, ambient operating temperature and endurance life.
Embodiment of above only for technology design and the feature of the present invention are described, its object is to allow and is familiar with technique
People understands present disclosure and is carried out, and can not limit the scope of the invention with this, all according to present invention spirit
The equivalence that essence is done changes or modifies, and all should contain within the scope of the present invention.
