絶縁テープで覆う必要がなくなる。(Function) The coil bobbin of the present invention has a pair of flanges formed on both sides of the body and covers the second coil of the body, so the flanges act as an insulator and prevent abnormal high voltages such as lightning surges from flowing into the coil. Even if it comes in, there is no discharge from this coil to the metal wire,
No more burning out of the coil. Furthermore, by making the brim on both sides of the chest an insulating material, there is no need to separately cover the coil with insulating tape.
