Definitions

  • the bottom part 1 together with the box-like cover 2 forms the relay housing.
  • the bottom part 1 has spaced apart and parallel to each other, upwardly projecting partitions 101.
  • the electromagnet is arranged. It consists of the coil body 3 with the winding 4, an E-shaped yoke 5 made of a U-shaped, upright flat material which surrounds the coil body 3 with the two yoke outer legs 5 '.
  • the yoke core 7, which is circular or elliptical in cross section and forms the middle leg of the E-shaped yoke 5, is fastened to the base 6 of the yoke 5. This protrudes through the coil body 3.
  • the free leg ends 8 and 9 of the yoke outer leg 5 'and the free end 10 of the yoke core 7 protrude beyond the coil flange 11 of the coil body 3.
