Description

Technical Field

[0001] This utility model relates to the field of primary coil pressing technology, and in particular to a primary coil pressing device for an ignition coil. Background Technology

[0002] Ignition coils for internal combustion engines are used in engines such as motors to generate a spark discharge from the spark plug. In an internal combustion engine ignition coil, a primary coil, intermittently energized from the igniter, and a secondary coil, which generates a high voltage through an induced magnetic field when the energization of the primary coil is cut off, are arranged concentrically. Typically, the primary coil is wound within a resin primary coil holder, and the secondary coil is wound within a resin secondary coil holder.

[0003] A common ignition coil contains two sets of coils: a primary coil and a secondary coil. The primary coil uses thicker enameled wire, typically about 0.5-1 mm thick, wound with about 200-500 turns. The secondary coil uses thinner enameled wire, typically about 0.1 mm thick, wound with about 15,000-25,000 turns. One end of the primary coil is connected to the vehicle's low-voltage power supply, and the other end is connected to the switching device.

[0004] However, during the assembly of the ignition coil, the primary coil needs to be assembled and fitted together by inserting the rubber-coated iron core into the secondary coil. In actual production, it is often necessary for personnel to use simple tools for pressing, which is time-consuming, labor-intensive, and inefficient. It is also easy for the pressing to fail, which affects the overall quality of the primary coil. Utility Model Content
