In automotive ignition system, ignition coil provides the important execution unit of ignition energy for air and fuel oil mixture in ignition engine cylinder, and ignition coil magnetic core is as the core of ignition coil, its structure used and material, the ignition energy for ignition coil has important impact.
Existing ignition coil magnetic core mostly is silicon steel sheet or ferroalloy sheet is stacked is integrally fixed, and form ellipticity or square frame shape, this type of fabrication of iron core is comparatively complicated, need design and overlap diel more, different size stack of laminations efficiency is lower, not only production cost is higher, and for ignition energy require comparatively high-engine time, effectively can not utilize ignition energy, cause fuel availability low, waste emission amount is larger, the resistance to elevated temperatures of this magnetic core is lower simultaneously, the startup impulsive force can born when high temperature is less, therefore easily cause the replacement frequency of ignition coil higher, add the consumer cost of car owner.
Summary of the invention
The purpose of this utility model is according to the problems referred to above, and provide a kind of high-energy ignition wound core, this magnetic core adopts new material and structure, the reliability of high-energy ignition can be put forward, heat-resisting quantity is comparatively strong, can effectively utilize higher ignition energy, bear larger startup impulsive force.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of high-energy ignition wound core, comprises cylinder and end cap, it is characterized in that: described cylinder and end cap are one-body molded through voltage stabilizing technique by soft-magnetic composite material respectively; The surface of described cylinder and end cap is all fitted with comparatively smooth insulating material; Described end cap comprises upper end cover and bottom end cover, and the end face of the two is the major arc face of same ratio; Described cylinder and bottom end cover integrated, non-dismountable, described upper end cover has foursquare through hole, and the top of cylinder is processed with the square termination corresponding to the square through-hole of upper end cover.
The insulating material of described cylinder and end cover surface laminating is smooth and the sub-film of the good polyurethane of thermal endurance.
The through hole of described cylinder termination and upper end cover is matched in clearance.
The length of diagonal angle hypotenuse of the square termination of described cylinder and the equal diameters of cylinder.
The wherein one side of described upper end cover is provided with positioning pit, is convenient to when mounted to the identification in upper end cover direction.
The corner of described end cap is all through chamfered.
Technique effect of the present utility model:
