Description

Technical Field

[0001] The present invention relates to the technical field of electromagnetic components, in particular to an electromagnetic component with a co-directional exhaust structure and a production process. Background Art

[0002] The skeletons in existing electromagnetic components all have pins, and the pins are inserted into the skeletons through an insertion machine. Due to air resistance, it is very difficult to insert the pins. In order to enable the pins to be inserted into the skeletons more smoothly, designers need to vertically and reversely set an exhaust hole in the reverse direction of pin insertion, similar to an L-shaped hole. The vertical section is the part where the pins are inserted, and the horizontal section is the part for exhausting air. That is, two holes need to be opened to insert the pins. Otherwise, the insertion machine cannot successfully insert the pins, or the pins are prone to deformation and bending. If too many exhaust holes are opened, the overall strength of the product will be insufficient, and production will be difficult, reducing the production speed and increasing the cost to a certain extent. At the same time, the pins will generate heat due to friction during the insertion process. When the temperature rises to a certain level, it will have a heat treatment effect on the pins to a certain extent, that is, the pins are more likely to rust, and the exhaust holes may also cause creepage due to the entry of other components or wire dust. To a certain extent, there are certain potential safety hazards. Summary of the Invention
