Abstract
The invention discloses an ignition coil with a closed magnetic circuit. The ignition coil comprises a shell body, an iron core, low-voltage wiring terminals, a high-voltage wiring terminal and a winding, wherein the shell body is provided with the low-voltage wiring terminals, the iron core is arranged in the shell body, the winding is arranged in the iron core, and the high-voltage wiring terminal is arranged on the upper portion of the winding. According to the ignition coil with the closed magnetic circuit, by the adoption of the iron core shaped like the Chinese character 'ri', magnetic hysteresis of the iron core is reduced; due to the fact that a magnetic circuit of the ignition coil is composed of the iron core extremely high in magnetic permeability, magnetic leakage is extremely low, and the energy conversion rate of the ignition coil is high.
Description
Technical field
The present invention relates to a kind of closed magnetic circuit ignition coil.
Background technology
The effect of ignition coil is to change the low pressure of power supply into high pressure, so that sparking-plug electrode produces the electric spark of lighting blender, conventional contact formula ignition system is all used the ignition coil of open-flux path substantially, open-flux path ignition coil in the course of the work, inefficiency, magnetic resistance is large, and magnetic leakage loss is more.
Summary of the invention
Goal of the invention: the object of the invention is, in order to solve the deficiencies in the prior art, provides a kind of simple in structure, and cost is low, the reliable closed magnetic circuit ignition coil of working stability.
Technical scheme: in order to realize above object, a kind of closed magnetic circuit ignition coil of the present invention, it comprises housing, iron core, low tension terminal, high tension terminal and winding, described housing is provided with low tension terminal, in housing, be provided with iron core, in described iron core, be provided with winding, the top of winding is provided with high tension terminal.
Described iron core is " day " font.
Described winding is comprised of armature winding and secondary winding.
Beneficial effect: a kind of closed magnetic circuit ignition coil provided by the invention, by adopting " day " shaped iron core, therefore, reduced hysteresis unshakable in one's determination, because the magnetic circuit of ignition coil forms by the high iron core of permeability, thereby leakage field is few, and the energy conversion rate of ignition coil is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is front view of the present invention.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the present invention.
Be illustrated in figure 1 a kind of closed magnetic circuit ignition coil of the present invention, it comprises housing 1, iron core 2, low tension terminal 3, high tension terminal 4 and winding 5.
Closed magnetic circuit ignition coil of the present invention, by adopting " day " shaped iron core 2, the space of leaving in unshakable in one's determination 2 is in order to reduce by unshakable in one's determination 2 hysteresis, because the magnetic circuit of ignition coil is by high iron core 2 formations of permeability, thereby leakage field is few, the energy conversion rate of ignition coil is high.
Above-mentioned embodiment is only explanation technical conceive of the present invention and feature, its objective is to allow to be familiar with these those skilled in the art and can to understand content of the present invention enforcement according to this, can not limit the scope of the invention with this.All equivalents that Spirit Essence has been done according to the present invention or modification, within all should being encompassed in protection scope of the present invention.
