コスト高の原因となつていた。 Conventionally, in this type of device, since the bracket also serves as a yoke for the magnetic circuit, a material that is both magnetic and conductive, such as an iron plate, is used. Therefore, it is fixed on the bracket. The coil is insulated from the bracket with an insulating sheet, adhesive, etc., but in order to take the coil out to the back of the bracket, it must be passed through a hole drilled in the bracket, and the insulating sheet must be inserted into this hole. , inserting adhesive etc. not only has poor workability, but also tends to make the insulation unreliable.Therefore, conventionally,
An electrically insulating tube was placed over the coil terminal and inserted through the hole in the bracket, but it was difficult to cover the coil terminal with a tube.
This was a cause of high costs.
