Since the terminal insertion part to insert is provided, it is suitable with a simple structure.
The first terminal can be accurately placed on the reel, and the terminal insertion part
Is a terminal insertion hole that does not penetrate, so the curved part of the first terminal
It is possible to secure the insulation distance between the second terminal and the winding
It can prevent the occurrence of short circuit.
