Abstract
The utility model relates to an ignition coil and particularly relates to a protecting jacket of an ignition coil for an automobile. The ignition coil comprises a jacket, wherein an ignition coil iron core is stuck to and wrapped on the inner surface of the jacket, and the jacket is made of elastic silicon gel. By using the protecting jacket provided by the technical scheme of the utility model, the epoxy resin of the ignition coil for the automobile can be prevented from being cracked and broken down.
Description
Technical field
The utility model relates to a kind of ignition coil, is specifically related to the protective sleeve that a kind of automobile is used ignition coil.
Background technology
Existing automobile ignition coil parts mainly comprise iron core, primary coil, secondary coil, housing and the primary coil low pressure input that is connected with the outside and connect the high-voltage output end of secondary coil and respectively organize inserting terminal.During assembling, will be packed in the housing by the coil block that iron core, primary coil and secondary coil consist of, and by encapsulating from the case top infusion epoxy resin.
The iron core of this ignition coil is directly covered by epoxy resin, because core structure exists right angle faceted pebble and wedge angle, and forms the great solid body of hardness behind the epoxy resin cure.Cold and hot variations in temperature can occur during ignition coil work, because iron core is different with the epoxy expansion coefficient, make and produce stress in the epoxy encapsulation body, and occurrence positions deformation, and structure length is larger, stress is larger, can peel off or the crack by initial ring epoxy resins face in right angle and the wedge angle stress concentration portion position of iron core, causes product to puncture and loses efficacy.
The utility model content
The technical problems to be solved in the utility model provides the protective sleeve that a kind of epoxy resin that can prevent from encapsulating iron core breaks.
In order to solve the problems of the technologies described above, the utility model provides the protective sleeve that prevents that automobile ignition coil epoxy resin cracking from puncturing, and is fitted and the overcoat of parcel ignition coil iron core consists of by inner surface, and described overcoat material is elastic silica gel.
Adopt the protective sleeve that automobile ignition coil epoxy resin cracking punctures that prevents of technique scheme to have following advantage: owing to adopted the elastic silica gel making; after the epoxy resin injection moulding; between epoxy resin and iron core, form the buffer insulation layer of a softness; avoid peeling off or the crack at right angle and the wedge angle stress concentration portion position initial ring epoxy resins face of iron core, more can avoid ignition coil to puncture and lose efficacy.
As preferred version, in order to guarantee the elastic effect of overcoat, the thickness that limits described overcoat is 1～5mm.
As preferred version, in order to guarantee the elastic effect of overcoat, further reduce again cost simultaneously, the thickness that limits described overcoat is 1mm.
Description of drawings
Fig. 1 is the cross-sectional view that the utility model embodiment prevents the protective sleeve that automobile ignition coil epoxy resin cracking punctures.
Embodiment
Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:
As shown in Figure 1, the utility model provides a kind of protective sleeve that prevents that automobile ignition coil epoxy resin cracking from puncturing, and is fitted and the overcoat 1 of parcel ignition coil iron core consists of by inner surface, and the material of overcoat 1 is elastic silica gel, and the thickness of overcoat is 1mm.
Because overcoat 1 has adopted the elastic silica gel making, after the epoxy resin injection moulding, it forms the buffer insulation layer of a softness between epoxy resin and iron core, avoid peeling off or the crack at right angle and the wedge angle stress concentration portion position initial ring epoxy resins face of iron core, more can avoid ignition coil to puncture and lose efficacy.
Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection range of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
Claims (3)
