問題があった。Conventionally, terminals were sealed by fitting a grommet into the cover and inserting a lead wire into the grommet, or by caulking and fixing an eyelet to the cover, and using the eyelet as a relay point to connect the end of the excitation coil from inside the relay. Lead wires for external extraction are soldered, and the solder is raised to form a seal. However, with the above-mentioned conventional sealing method, the assembly method is complicated and takes a lot of man-hours, and there are also problems such as solder dripping inside the relay and causing insulation failure.
