Solenoid valve - coil unit for a solenoid valve and a process for the preparation of a solenoid valve - coil unit

摘要

A solenoid valve - coil unit has a magnetic coil (104) and a related printed circuit board (106), wherein the magnetic coil (104) and the printed circuit board (106) of a molding compound (118) are coated, and on the printed circuit board (106) an led (108) is arranged, which a switching state of the magnetic coil (104) indicates. The led (108) is at least partially from the molding compound (118) surround. It is a light guide element (122) is provided, the thus in contact with the led (108) is arranged, that it (108) by the led light is emitted at an outer surface of the solenoid valve - coil unit (100) derives. The solenoid valve - coil unit (200) is produced by applying a deformable, transparent mass (124) to the led (108) of a preassembled assembly with the magnetic coil (104) and the printed circuit board (106), on which the led (108) is arranged, is applied and the preassembled assembly is inserted into a mold. The light guide element (122) is in contact with the transparent mass (124) is arranged, and the preassembled assembly is with the molding compound (118) wrapped.
