Description
Technical field
The utility model belongs to ignition system technical field, specifically discloses a kind of ignition coil.
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 generate the voltage of 20-40KV by setpoint frequency power on/off, electric spark is generated by spark plug.With automobile point
The development of fiery system, the structure of automobile ignition coil is just towards miniaturization, lightweight and energetic development.
It can be had the following problems using ignition coil in the prior art：1) iron-core coil is by two identical U-shaped iron
Core docks to form cyclic structure, and two U-shaped iron core sides are to be fixedly connected, there are air gap between the both ends of the surface of the other side, the one of air gap
Side is adhesively fixed with primary coil skeleton by epoxy resin, and the other side is fixed using the artificial assemble welding that carries out, production assembly
Efficiency is low；2) iron core of ignition coil is directly covered with epoxy, and the epoxy resin after solidification forms the great solid-state of hardness
Object, and core structure is there are right angle faceted pebble and wedge angle, when working cold and hot temperature change can occur for ignition coil, due to iron core and
Epoxy expansion coefficient is different, makes to generate stress in epoxy encapsulation body, position deformation occurs, at the right angle and point of iron core
The epoxy resin at angle stress concentration position can peeling-off under the action of stress or crack.
Utility model content
The purpose of this utility model is to provide a kind of ignition coils, to solve the U-shaped iron core of ignition coil two using weldering
Connect fixation, the low problem of production efficiency of assembling.
In order to achieve the above object, the base case of the utility model is：A kind of ignition coil, including coil mechanism, also
Including cyclic annular iron core, two opposite clamping mechanisms of position, the coil mechanism are fixedly connected on the inside of the ring-type iron core
Both ends can be respectively engaged in clamping mechanism.
The operation principle of this base case is with advantageous effect：Iron core in this ignition coil is integrated ring-type, in life
It produces in process, is that the both ends of coil mechanism are respectively engaged in clamping mechanism to assemble, with point in the prior art
Firewire circle is compared, 1) iron core is integrated ring-type, is welded and fixed two halves iron core without passing through welding, it is well known that welding
It is difficult to carry out mechanical automation production, and this ignition coil eliminates welding step, simplifies production to be in the industrial production
Step, production is easy, is produced convenient for mechanical automation, greatly improves the production efficiency of ignition coil；2) this ignition coil
Assembly method change, the both ends of coil mechanism, which are connected in clamping mechanism, is assembled, Assembly And Disassembly mode equal ten
The simplicity divided, can greatly improve production efficiency.
Further, soft system set, the epoxy resin protective case larger with hardness in the prior art are cased with outside the cyclic annular iron core
It compares, the setting of soft system set is not easily stripped or cracks first in the cold and hot temperature change of ignition coil；Secondly, ignition coil exists
When being collided by the external world, soft system set can play preferable cushioning effect.
Further, the clamping mechanism includes the lug boss of intermediate recessed portion and both sides, and the recessed portion is equipped with the
One inhales iron, and the both ends of the coil mechanism are equipped with second and inhale iron, and described first inhales the face magnetic pole phase that iron inhales iron phase pair with second
It is different.First suction iron and the second suction iron can be further ensured that the Assembly stability of coil mechanism and cyclic annular iron core.
Further, the material of the soft system set is silica gel, and silica gel concertina type is strong, and soft system obtained covers not easy to crack, valence
It is honest and clean to be easy to get, and there is preferable cushioning effect.
Further, cyclic annular iron core is stretched out at the top of the clamping mechanism, can be further ensured that coil mechanism and cyclic annular iron
The Assembly stability of core.
Description of the drawings
Fig. 1 is the utility model front view；
Fig. 2 is the utility model vertical view；
Fig. 3 is the structural schematic diagram of the utility model clamping mechanism.
Specific implementation mode
The utility model is described in further detail below by specific implementation mode：
Reference numeral in Figure of description includes：Cyclic annular iron core 1, coil mechanism 2, clamping mechanism 3, recessed portion 4, protrusion
Portion 5.
As shown in Figure 1, Figure 2 and Figure 3, a kind of ignition coil, including coil mechanism 2 and cyclic annular iron core 1, cyclic annular iron core 1
Inside is bolted to connection two opposite clamping mechanisms 3 of position.Cyclic annular iron core 1 is stretched out at the top of clamping mechanism 3.Card
Connection mechanism 3 includes the lug boss 5 of intermediate recessed portion 4 and both sides, and recessed portion 4 is equipped with first and inhales iron, the both ends of coil mechanism 2
Iron is inhaled equipped with second, the first suction iron is different with the second suction one face magnetic pole of iron phase pair.
Soft system set is cased with outside cyclic annular iron core 1, the material of the preferred soft system set of the present embodiment is silica gel.The setting of soft system set exists
It is not easy to crack when the cold and hot temperature change of ignition coil；And ignition coil can play preferably slow when being collided by the external world
Punching acts on.
Cyclic annular iron core 1 in this ignition coil is integrated ring-type, is by the two of coil mechanism 2 in process of manufacture
End, which is respectively engaged in clamping mechanism 3, is assembled, and first on recessed portion 4 inhales iron and inhale iron with the second of 2 both ends of coil mechanism
Attract, cyclic annular iron core 1 is stretched out at the top of clamping mechanism 3, can be further ensured that the assembly of cyclic annular iron core 1 and clamping mechanism 3
Stability.
Above-described is only the embodiments of the present invention, and the common sense such as well known concrete structure and characteristic are herein in scheme
It does not describe excessively.It should be pointed out that for those skilled in the art, in the premise for not departing from the utility model structure
