Abstract
The invention discloses a coiling method of a low-voltage winding of an ignition coil. The coiling method is used for coiling the low-voltage winding in the ignition coil of an automobile engine, and comprises the following steps of pressing a hard wire on a side wall of a low-voltage skeleton of the ignition coil, placing the wire on the low-voltage skeleton at the periphery of a magnetic core, allowing the wire to surround the magnetic core toward a direction from one side of the magnetic core, coiling and forming a coil part. The coiling method of the low-voltage winding of the ignition coil can allow a coiling copper wire of the low-voltage skeleton of the ignition coil of the automobile engine to be smooth.
Description
Technical field
The present invention relates to a kind of on coil case the method for coiling coil, relate in particular to a kind of method for winding that carries out winding operation for the ignition coil mesolow winding to automobile engine.
Background technology
In automotive engine ignition system, ignition coil is a kind ofly to provide the execution unit of ignition energy for air and fuel oil mixture in the ignition engine cylinder, it is a kind of special burst transformer based on electromagnetic induction principle, and low voltage transition that can 10-12V becomes the even higher voltage of 25000V.
Why ignition coil can become high voltage with low tension on car, is due to the form identical with common transformer being arranged, and the turn ratio of low pressure winding and high pressure winding is large.But the ignition coil working method is different with common transformer, and common transformer is continuous operation, and ignition coil is interrupter duty, and its rotating speed different according to engine carries out energy storage and exoergic repeatedly with different frequencies.
When the low pressure winding switched on power, along with very strong magnetic field of growth surrounding generation of electric current, iron core had stored magnetic field energy; When switching device disconnects the low pressure winding circuit, decay rapidly in the magnetic field of low pressure winding, and the high pressure winding will induce very high voltage.The magnetic field disappearance speed of low pressure winding is faster, and the electric current that electric current disconnects moment is larger, and the turn ratio of two windings is larger, and to induce voltage higher for the high pressure winding.
At present, the assembling mode of ignition coil mostly is manual operations, because the gap of high pressure skeleton and low pressure winding is less, it is not fine easily producing parabola and permeating, and in process of production, can cause easily that because epoxy resin filling is inhomogeneous electrion causes the copper cash of low pressure winding to puncture after the generation parabola, cause potential safety hazard and coil disabler, low pressure winding and secondary framework frictional force are larger, cause the low easy short circuit of product quality, assembling quality relatively poor, and need more assembler.
Therefore, provide that a kind of to make the smooth ignition coil low pressure winding method for winding of coiling copper cash of car engine ignition coil low-voltage framework be the technical problem that those skilled in the art need solution badly.
Summary of the invention
The purpose of this invention is to provide a kind of smooth ignition coil low pressure winding method for winding of coiling copper cash that can make car engine ignition coil low-voltage framework.
To achieve these goals, the invention provides a kind of ignition coil low pressure winding method for winding, be used for the ignition coil mesolow winding of automobile engine is carried out winding operation, comprise the following steps: at wire of low-voltage framework side wall and pressure of ignition coil; This wire is placed on the low-voltage framework of magnetic core periphery, this wire, winds the line and forms coil portion on the low-voltage framework of described magnetic core periphery towards a directional ring from low-voltage framework one side of described magnetic core periphery.
Preferably, it is parallel with the axis of described magnetic core that described wire is pressed in the position of described low-voltage framework sidewall.
Preferably, described wire is pressed in the position, axis of low-voltage framework sidewall.
Preferably, described wire is the copper cash with the insulation paint film.
Compared with prior art, ignition coil low pressure winding method for winding provided by the present invention, by first wire of low-voltage framework side wall and pressure at ignition coil before coiling, this wire carries out in the coiling process, for winding portion all the time by this wire concora crush, make the wire of follow-up coiling process coil smooth, make the epoxy resin filling of follow-up filling even, prevent from causing that electrion causes puncturing the copper cash of low pressure winding, and can reduce frictional force between low pressure winding and secondary framework, improve the quality of products and packaging efficiency.
