SOLENOID VALVE AND SOLENOID VALVE ELECTRODE MANUFACTURING DEVICE

摘要

PROBLEM TO BE SOLVED: To improve productivity and quality of a solenoid valve. SOLUTION: An inner yoke 22 and an end yoke 20 as a minus electrode are attached to one end of a bobbin 16 around which a coil 18 is wound. A terminal 34 as a plus electrode is attached to a projection 32 of the bobbin 16 projected from the end yoke 20. Terminals of the coil 18 are wound around a boss 21 of the end yoke 20 and a boss 36 of the terminal 34, followed by soldering. The bobbin 16 formed with the electrodes is fixed into body 11. Resin 38 is charged from an opening 11b into the body 11. A plunger 24 inside the bobbin 16 is relatively moved along an axis L together with a valve element 28, by electromagnetic force of the coil 18.
