Description

Automobile ignition coil

Technical field

The utility model is related to a kind of automobile igniter, and in particular to a kind of automobile ignition coil.

Background technology

As automotive gasoline engine develops to the direction of high rotating speed, high compression ratio, high-power, low oil consumption and low emission, Traditional igniter has been not suitable with use requirement.The core component of igniter is ignition coil and switching device, is improved The energy of ignition coil, spark plug can just produce the spark of enough energy, and this is that igniter adapts to Modern Engine operation Primary condition.

Existing automobile ignition coil is from inside to outside successively by groups such as iron core, high-tension coil group, low-voltage coil group and shells Into its structure comes in contact bad phenomenon often due to combining defective tightness in thump, affects the point of ignition coil Fiery performance and shorten service life.

The content of the invention

To solve the above problems, the purpose of this utility model is to provide a kind of compact conformation, the automobile point of reliable operation Live wire circle, so as to improve the performance and used life of ignition coil.

For achieving the above object, the utility model provides following technical scheme：A kind of automobile ignition coil, including iron Core, high-tension coil group, low-voltage coil group and shell, are installed with HV Terminal and low-voltage terminal on described shell, described Iron core be made up of the first iron core and the second iron core, described inside the shell is provided with the first accommodating cavity matched with the iron core, Described the first iron core and the second described iron core split are arranged in the first described accommodating cavity, described the first iron core and institute The the second iron core split stated forms the groove matched with the high-tension coil group, and described high-tension coil group is placed on the groove Interior, described high-tension coil group is connected by the contact pin that surface is coated with copper and tin with described HV Terminal, and described shell also sets There is the second accommodating cavity, low-voltage coil group is installed in the second described accommodating cavity, described low-voltage coil group is coated with by surface The conducting strip of copper and tin is connected with described low-voltage terminal, described the first accommodating cavity with a fixed mount and shell aperture after pour Enter epoxy resin, there is the arrangement draw-in groove being engaged by clamping with described shell on described low-voltage terminal, the arrangement draw-in groove is in side Shape groove.

Described shell is convexly equipped with the insulation sleeve for being wrapped in the HV Terminal side face.

By having the beneficial effect that for being reached using above-mentioned technical proposal：Iron core fixes the first accommodating cavity in the housing In, high-tension coil group is fixed in the groove that the first iron core and the second iron core split are formed, and low-voltage coil group is fixed on the second appearance Put in chamber, high-tension coil group is connected by being coated with the contact pin of copper and tin with HV Terminal, low-voltage coil group is by being coated with leading for copper and tin Electric piece is connected with low-voltage coil group, can so make high-tension coil group and low-voltage coil group compacter with the cooperation of housing respectively, Its electric conductivity is effectively improved, so as to ensure that the functional reliability of ignition coil, compact conformation, reliable operation has so just been reached Technique effect, so as to improve the performance and used life of ignition coil.

Description of the drawings

The utility model is further described with reference to the accompanying drawings and detailed description.

Fig. 1 is the top view of the utility model specific embodiment；

Fig. 2 is the sectional view of the utility model specific embodiment；

Fig. 3 is the structure chart of the utility model specific embodiment mesolow terminal.

Specific embodiment

The utility model is specifically described below by embodiment, is served only for carrying out further the utility model Explanation, it is impossible to be interpreted as the restriction to the utility model protection domain.

As shown in Fig. 1-Fig. 3, the utility model discloses a kind of automobile ignition coil, including iron core 1, high-tension coil group 2nd, low-voltage coil group 3 and shell 4, are installed with HV Terminal 41 and low-voltage terminal 42 on shell 4, iron core 1 is by the first iron core 11 and second iron core 12 constitute, is provided with the first accommodating cavity 43 matched with iron core 1, the first iron core 11 and the second iron in shell 4 The split of core 12 is arranged in the first accommodating cavity 43, the first iron core 11 and the split formation of the second iron core 12 and the phase of high-tension coil group 2 The groove 13 matched somebody with somebody, high-tension coil group 2 is placed in the groove 13, and high-tension coil group 2 is coated with the contact pin 5 and height of copper and tin by surface Pressure side 41 connects, and shell 4 is additionally provided with the second accommodating cavity 44, and in the second accommodating cavity 44 low-voltage coil group 3, low-voltage coil are provided with The conducting strip 6 that group 3 is coated with copper and tin by surface is connected with low-voltage terminal 42.Surface is coated with the contact pin 5 and conducting strip 6 of copper and tin can be had Effect improves electric current delivery efficiency so that the work of ignition coil is more efficiently and stable.

First accommodating cavity 43 from a fixed mount 7 and shell 4 be open with after pour into epoxy resin 8, on low-voltage terminal 42 have There is the arrangement draw-in groove 421 being engaged by clamping with shell 4, the arrangement draw-in groove 421 is square groove.Improve the insulating properties of iron core 1 with And make iron core 1 fix relatively reliable, effectively improve the compactedness of structure.
