Title:
RESIN MOLDED SOLENOID COIL AND SOLENOID VALVE EQUIPPED THEREWITH
Document Type and Number:
WIPO Patent Application WO/2021/054071
Kind Code:
A1
Abstract:
A solenoid coil in which a wire (magnet wire) 15 wound around a bobbin, and a pair of connection terminals (first terminal 31a and second terminal 31b) for connecting the wire to an external circuit are covered with molding resins 51 and 51a, and a flywheel diode 41 is connected between the pair of connection terminals, wherein the first terminal has a diode connection portion to which the leading end of the wire is connected and the diode can be connected, the second terminal has a diode connection portion to which the trailing end of the wire is connected and the diode can be connected, a coating layer made of a molding resin has a diode mounting hole 51c that leads to each diode connection portion and can accept the diode so that the diode can be mounted after the coating layer is formed, and the mounting hole is closed by a sealing material provided separately from the molding resin.
