Abstract
The utility model discloses an ignition coil shell structure, wherein, including housing body, housing body's lateral wall's internal surface is provided with and is arranged in the spacing protruding structure of the primary and secondary winding to packing into housing body. The ignition coil shell structure aims to solve the technical problems that a primary winding is easy to drop and a secondary winding is scrapped in the prior art.
Description
Technical Field
The utility model relates to a shell structure field especially relates to an ignition coil shell structure.
Background
In recent years, the automotive electronics industry in China is rapidly developed, the demand for ignition coils is more and more large, the quality requirement of the ignition coils is more and more strict, and the technical index of product performance is improved. Higher requirements are also put forward to the encapsulation process of the product.
The ignition coil is an induction coil generating high voltage electricity, the high voltage electricity generated by the ignition coil for an automobile engine reaches more than 35KV, so that the key of improving the product quality, enhancing the reliability and prolonging the service life of the ignition coil is to ensure the insulation strength of the ignition coil.
In the ignition coil assembly process in the prior art, the primary and secondary winding assemblies are not provided with any restraining and limiting structure after being arranged in the shell, and the poor contact between the secondary winding assembly and the shell copper head can be caused by the poor phenomena of shaking, rebounding, falling and the like of the primary and secondary winding assemblies easily occurring during the assembly of the product. The secondary framework is too high after rebounding, and the framework or welding points are easily exposed during glue pouring, so that the appearance of the glue surface of the product is poor. The primary and secondary winding assemblies fall off, so that the secondary winding is easily scrapped.
