Description
Technical field
The utility model relates to a kind of automobile ignition coil.
Background technology
Encapsulating must be carried out to ensure insulating properties in ignition coil final production technique larger at present, but this process for filling colloid into easily produces glue cracking for larger ignition coil, for ensureing that glue does not ftracture in bulk-solidifying process, usually repeatedly encapsulating is adopted in technique, because repeatedly encapsulating needs multiple working procedure, encapsulating, solidify, repeatedly carry out, cause production efficiency low, the problem of labor intensive cost.Secondly ignition coil iron core conversion efficiency is usually low at present.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of ignition coil.
The technical scheme in the invention for solving the technical problem is: a kind of ignition coil, comprises housing, coil assembly and fluid sealant.Described housing comprises inner casing and shell, is provided with inner casing outside described coil assembly, and described inner casing assembling in the enclosure; Be provided with a point edge in described inner casing, described point of edge is provided with curved surface, is provided with groove of sunkening cord above described inner casing, adopts the disposable embedding of fluid sealant after described ignition coil assembling.Using inner casing to be separated by encapsulating makes disposable encapsulating not easy to crack, and solving the larger ignition coil of volume cannot the problem of disposable encapsulating; Secondly curved surface is set on point edge, fluid sealant is contacted with a point edge more tight, not easy to crack.
Described coil assembly comprises iron core, low-voltage framework, high pressure skeleton and primary coil and secondary coil, described iron core comprises a U-iron core and T-shaped iron core, described T-shaped iron core is arranged with low-voltage framework, described low-voltage framework is wound with primary coil, high pressure skeleton is enclosed with outside described primary coil, described high pressure skeleton is around with secondary coil, the left arm of described U-iron core is long, right arm is short, top, described T-shaped iron core top is attached to inside the left arm of described U-iron core, the right arm top of described U-iron core is attached to described T-shaped iron core lower end upper side wall, soft magnetism is provided with between inside the left arm of described T-shaped iron core top and U-shaped iron core.Described soft magnetism is arranged between two discrete iron cores and conversion efficiency is increased, and the setting of UT sections can change soft magnetism thickness with designing requirement and not change core configuration in addition.
Further, described inner casing lower end is provided with location hole, and in described inner casing, a point edge is two, and described point of edge top-surface camber is two.
Use step of the present utility model is identical with general ignition coil, does not repeat them here.
The beneficial effects of the utility model are: solving current large ignition coil cannot the difficult problem of disposable encapsulating, and decrease processing step, reduce consuming time and labour, increase yield, the change of iron core makes ignition coil conversion efficiency increase in addition, more energy-conservation.
