Abstract
The invention relates to a high-voltage breakdown prevention structure of an automobile pen type ignition coil and a manufacturing method. The high-voltage breakdown prevention structure comprises a high-voltage framework, an iron core and an iron core cap, wherein a plurality of convex iron core positioning ribs are poured at the lower part of an inner cavity of the high-voltage framework so that the formed inner cavity is matched with the outer diameter of the iron core; the iron core cap is a shell matched with the iron core; the iron core is arranged in the inner cavity formed by the iron core positioning ribs; the iron core cap is worn at the top of the iron core so that the top of the iron core is fixed in the inner cavity of the high-voltage framework; and epoxy resin is poured to seal. The high-voltage breakdown prevention structure of the automobile pen type ignition coil has the beneficial effects that under the condition that the cost of materials is not increased, the breakdown rate of the pen type ignition coil is reduced and the yield of the product is improved.
Description
Technical field
The present invention relates to a kind of automobile pen type fire coil, particularly a kind of anti-high-voltage breakdown structure of automobile pen-type ignition coil and manufacture method.
Background technology
In common pen type fire coil product, modal failure mode is that high pressure is to other low-pressure structure disruptive discharge, the modal form that punctures is due to iron core location and skeleton decentraction, high-voltage breakdown high pressure skeleton wall and epoxy resin is caused to discharge to iron core, can reasonably design iron core location structure and insulation distance, in traditional pen-type ignition coil structural design, just serve quite crucial effect.
Summary of the invention
In view of the deficiency that prior art exists, the invention provides a kind of anti-high-voltage breakdown iron core of automobile pen-type ignition coil, the technical scheme taked is, a kind of anti-high-voltage breakdown structure of automobile pen-type ignition coil and manufacture method, comprise high pressure skeleton, iron core, core cap, it is characterized in that: the iron core positioning bar being cast with several projections in high pressure framework inner cavity bottom, the inner chamber making it be formed and iron core major diameter fit, core cap is the housing coordinated with iron core, iron core is placed in the inner chamber of iron core positioning bar formation, core cap is worn in iron core top, iron core top is maintained static at high pressure framework inner cavity, infusion epoxy resin seals.
The anti-high-voltage breakdown structure of automobile pen-type ignition coil and manufacture method divide following steps, one, calculate insulation distance, according to selecting iron core, high pressure skeleton, core cap root properties of materials to calculate insulation distance, general insulation distance should be greater than 40KV voltage breakdown value; Two, compute location muscle height, according to insulation distance compute location muscle height; Three, the iron core positioning bar of several projections is cast with in high pressure framework inner cavity bottom to ensure that iron core is located between two parties at skeletal internal; Four, make core cap, make core cap according to high pressure framework inner cavity and iron core external diameter, maintain static in high pressure framework inner cavity after making iron core top put on core cap.Five, assemble, be placed in by iron core in the inner chamber of iron core positioning bar formation, core cap is worn in iron core top, and iron core top is maintained static at high pressure framework inner cavity, and infusion epoxy resin seals.
The invention has the beneficial effects as follows, when not increasing material cost, what reduce pen-type ignition coil punctures rate, improves conforming product rate.
Accompanying drawing explanation
