Description

Technical Field

[0001] The utility model relates to the technical field of automobile ignition coils, in particular to an automobile ignition coil assembly tool. Background Art

[0002] The automobile ignition coil is an important part of the internal combustion engine ignition system. The internal combustion engine ignition system is responsible for igniting at the right time in each cylinder to ignite the mixed gas and drive the piston to move. The traditional ignition system is usually divided into two types: distributed ignition system and direct ignition system. The ignition coil is to boost the low-voltage electrical energy to thousands of volts through electromagnetic induction to supply it to the spark plug. This high voltage can form an arc between the spark plugs to ignite the mixed gas in the cylinder. The ignition coil is usually composed of an iron core, a primary coil, a secondary coil and a high-voltage output terminal. The current first passes through the primary coil to generate a magnetic field. When the ignition system control circuit cuts off the current, the magnetic field collapses and induces a high-voltage pulse in the secondary coil. In recent years, the traditional distributed ignition system has been gradually replaced by the electronic ignition system. The electronic ignition system controls individual ignition coils through a computer, which can more accurately control the ignition timing and ignition method, improving fuel economy and engine performance.

[0003] When assembling the existing automobile ignition coil, the operator needs to install the ignition coil in a shell. However, since the ignition coil needs to be installed in the shell, the operator cannot see the situation inside the shell during installation, which makes it impossible to ensure whether the ignition coil is assembled correctly, resulting in many ignition coils being damaged. In view of the above problems, the inventor proposes an automobile ignition coil assembly tool for solving the above problems. Utility Model Content
