Problems solved by technology

[0003] However, in the existing electromagnetic interference protection structures, most of the shielding structures are directly installed on the capacitors connected by the two coils. This will not only cause the structure of the capacitors to be too large, which is not conducive to the arrangement, but also not conducive to stable combination installation, resulting in misalignment. It is not conducive to normal coupling and needs to be improved

Abstract

The invention discloses a method for changing an electromagnetic interference coupling path of an ignition coil. A U-shaped baffle is arranged, and a connecting pipe is fixedly connected to the surface of one side of the U-shaped baffle; the other end of the connecting pipe is fixedly connected with an arc hollow pipe; the other end of the arc hollow pipe is fixedly connected with a right-angle coupling pipe; a U-shaped fixing block is fixedly mounted on the surface of one side of the arc hollow pipe; fixing plates are arranged on the two sides of the U-shaped fixing block, mounting through holes are formed in the surfaces of the fixing plates; the surfaces of the other sides of the fixing plates are fixedly connected with transverse cylinders; shielding plates are fixedly connected to theside faces of the transverse cylinders, the surfaces of the shielding plates are located on one side of the U-shaped baffle, and a coil iron core is fixedly connected to the surface of the other sideof the U-shaped baffle, so that the use convenience and stability can be greatly improved, and the anti-interference effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of ignition coils, in particular to a method for changing an electromagnetic interference coupling path of an ignition coil. Background technique [0002] During the use of the ignition coil, due to the structural arrangement and its own ignition characteristics, electromagnetic interference will be generated and affect the normal operation of other components. In order to ensure safety and stability, protection is required. [0003] However, in the existing electromagnetic interference protection structures, the shielding structure is directly installed on the capacitor connected by the two coils, which will not only cause the structure of the capacitor to be too large, which is not conducive to the arrangement, but also not conducive to the stable combination installation, resulting in misalignment After that, it is not conducive to normal coupling and needs to be improved.
