Definitions

  • the present invention relates to an electromagnetic relay, in particular a miniature relay, according to the preamble of claim 1.
  • Such a relay is known, for example, from DE-PS 22 13 146 and DE-GM 18 28 023.
  • laterally projecting tabs are provided on the magnetic yoke, which each engage in a recess in a side wall during assembly.
  • the contact systems must be adjusted according to the installation position of the magnet system after installing the magnet system. This is relatively complicated and lengthy because of the elasticity of the contact building materials.
  • the object of the present invention is to design a relay of the type mentioned so that the adjustment of the contact system relative to the magnet system or of the armature actuating the contact system can be carried out quickly and easily.
  • connection elements 7 are formed, which lead to the contact system 8 protruding from the top, consisting of a contact connection 9, a contact spring 10 welded to it and movable contact elements 11, 12 attached to it, which cooperate with fixed contact elements 13 and 14, respectively .
  • a connecting element 7 is connected to the coil (not shown) of a magnet system 15, which still consists of the coil body 16, a coil core 17, a magnetic yoke 18 connected to the coil core 17 and a movable armature 19 which is designed as a cap anchor.
  • the latter is via a pressure spring 20th pressed against the end edge 21 of the magnetic yoke 18 and is thus pivotally mounted.
  • the pressure spring 20 can be attached to the spool body or molded onto it, so that it forms a structural unit with it.
  • one leg 22 of the armature 19 rests on the magnetic yoke 18.
  • a plastic switching cam 23 attached to the armature 19 can actuate the end 24 of the contact spring 10.
  • Two such housing shells 1 form a housing part in which the magnet system 15 is fixed in position.
  • This housing part can also consist of several parts, for example as described and illustrated in DE-GM 78 28 023.
  • two recesses 26 and 27 are arranged one behind the other in the side wall 3, as seen in the direction of the longitudinal axis 25.
  • a lateral extension 28 or 29 of the magnetic yoke 18 engages in these without play.
  • the lower surface 30 of the cutouts 26, 27 each has a support web 31 or 32 on which the shoulder 28 or 29 rests.
  • the contact point of the recess 26 provided on the left in FIG. 1 serves as a pivot point 33 for the magnetic yoke 18.
  • the magnet yoke 18 in the recess 27 can be lowered by pressing the cover part 5 with a hot and / or ULtraschaLL from above, the support web 32 softening the recess 27 and is compressed downwards. This process takes place while measuring the contact distance at the end 24 of the contact spring 10 attacking switching cams 23, for example by measuring the changeover point with the voltage applied to the contact system 8.
  • the stamp pressure is removed or the stamp is lifted off completely, so that the magnet system 15 in the adjusted position by the cooled and hardened, deformed support web 32 and at this point also pulled down, cooled and hardened part 34 of the cover part 5 is firmly held (Fig. 4).
  • the recess 27 with the support web 32 to be deformed is advantageously provided in the region of the end edge 24 of the magnetic yoke 18 serving as a pivot axis, and the lugs 29 are also arranged at the end of the magnetic yoke 18.
  • the support web 31 can also be formed by a corresponding shaping of the magnetic yoke 18 and the pivot point can thereby be fixed.
  • the ReLais can be closed with a blanket L 35 and, if necessary, with suitable measures, e.g. by shedding, be made wash-tight.
