Further, on upper shell, be provided with at least two buckles that wind the line, when enamelled wire place in circuit, first the enamelled wire on ignition coil buckled around coiling clip, prevent that enamelled wire is fixing and affect ignition coil, play the fixedly effect of enamelled wire.
Further, the first back-up block and the second back-up block mutually vertical being " ten " font, improve the stability of base, the design of " ten " font can make ignition coil be fixed in coil groove, plays spacing fixing effect.
Further, the chamfering on the first back-up block and the second back-up block is all circular arc chamfering, reduces friction, and makes ignition coil put into more easily coil groove.
Further, on the second fixed leg, be provided with louvre, improve the radiating effect of ignition coil, in the useful life of extension coil, improve the performance of ignition coil.
Further, between the 3rd guide vane end stop, the first fixed leg, the second fixed leg and the first back-up block, by reinforcement, be fixedly connected with, improve the intensity of ignition coil base.
The utility model, owing to having adopted technique scheme, has following beneficial effect:
Improved practicality, ignition effectiveness high, improved installation stability, extended useful life: the utility model adopts a plastic casing, and by enamelled wire, on housing, the first spacing ring and the second spacing ring be enamelled wire fixedly, prevents that enamelled wire from moving; Guide vane end stop on housing can make ignition coil play when mounted position-limiting action; Metal clips is surrounded by insulating paper outward, with reinforced insulation; Filler is reinforced insulation and prevents moisture intrusion, the thermal diffusivity having had, and temperature rise is lower; The back-up block of base is " ten " font, improves the stability of base, and the design of " ten " font can make ignition coil be fixed in coil groove, plays spacing fixing effect; Between the 3rd guide vane end stop, the first fixed leg, the second fixed leg and the first back-up block, by reinforcement, be fixedly connected with, improve the intensity of ignition coil base.The utility model is simple in structure, and low cost of manufacture is practical.
