Definitions

  • the invention relates to a method for producing a Electromagnetic relay according to claim 1.
  • DE-A-32 10 031 describes a generic method for Making an electromagnetic relay with a Non-cutting deformable coil core known by Cross-section reduction with a radial contact surface is provided, one of which is coaxial with the coil core an undercut provided pin.
  • a Coil core is for attachment to a flat leg a two-legged magnetic yoke and to hold one Coil determined.
  • the second, parallel to the coil core running leg of the magnetic yoke ends in one Cutting edge bearing for a folding anchor of the relay, which by energizing the coil against the end of the Coil core is movable.
  • the coil core of the relay is therefore between the Contact surface and its end remote from the spigot with excess length manufactured.
  • Part of the displaced material is said to be of the yoke leg in the undercut of the pin flow and also enclose this closely.
  • Another relay known from DE-A-28 32 507 has one rod or bolt-shaped, essentially cylindrical Coil core that carries a coil and one of them Forehead with the shorter leg of an L-shaped Anchor plate is riveted.
  • a relay contacts bearing Folding anchor can be swiveled around a swivel axis on the free one End face of the coil core arranged. He is from one Spring kept at a distance from the coil core and at current-carrying coil against the spring force to one Free face of the coil core forming the pole face used.
  • the adjustment is made in that the position of the swivel axis of the hinged anchor is precisely measured and the coil core by wobble rivets of its free Forehead is brought to the required length.
  • the coil is on the Coil core attached.
  • the tumbling rivet forms a flange on the free end face of the coil core, the at the same time the coil is fixed in the axial direction.
  • the tumbling rivet described has the disadvantage that it must be carried out very precisely to the coil core as exact as possible to the required length. she does not cause you due to the necessary precision negligible effort and thereby carries one considerable contribution to the cost of relay production.
  • a coil core whose for the The position of the hinged anchor in relation to the coil core is decisive Length before the coil core is connected to the Magnet yoke is adapted exactly to the required length. A There is no need to adjust the individual parts.
  • the coil core of the Relay has a contact surface for contact with the magnetic yoke, which ensures that the position for the hinged anchor with regard to the coil core, the relevant length of the Coil core when connecting the coil core to the Magnet yoke not changed.
  • the connection of the coil core with the magnetic yoke for example by riveting Screwing, by soldering, welding or gluing.
  • the invention also has the advantage that the high Investment costs and to be carried out with great effort Tumbling riveting is eliminated. Furthermore, the one pole face forming free end face of the coil core after it Connection with the magnetic yoke no longer processed. Rejects due to surface defects such as abrasion or Flaking of the pole face as a result of their processing omitted. Is a cycle time of one second or less possible when installing the relay according to the invention.
  • the distance from the magnetic yoke formed pivot axis of a base of the Magnet yoke on which the coil core is attached in Measure the direction of the axis of the coil core. So it will the height of the swivel axis over the base of the Magnet yoke measured. This is just a measure of one Measure part of the relay. With this measure, the location of the Anchor set in relation to the coil core, so that from this dimension determines the required length of the coil core can be.
  • the coil core by upsetting on the required length from its contact surface to the pole surface brought, with the coil core on the contact surface is supported.
  • the upsetting represents a quick and represents a simple process with which the coil core is positioned precisely the desired length can be brought.
  • the relay shown in FIG. 1 has a base plate 10 made of insulating material, on which an L-shaped, as a bent sheet metal part manufactured magnetic yoke 12 is attached.
  • a base plate 10 made of insulating material, on which an L-shaped, as a bent sheet metal part manufactured magnetic yoke 12 is attached.
  • the coil core 14 has a annular shoulder surface as a contact surface 116, which around a rivet pin 18 is arranged around for riveting serves with the magnetic yoke 12.
  • the coil core 14 has a flange 20, the free End face as a pole face 22 of the coil core 14 crowned is arched.
  • the coil core 14 carries a coil 24 which is in axial Direction between the short leg of the L-shaped Magnetic yoke 12 and the flange 20 of the coil core 14 is fixed.
  • a hinged anchor 26 At the free end of the longer leg of the magnetic yoke 12 is a hinged anchor 26 in a recess 28 of the Magnet yoke 12 pivotally mounted.
  • pivot axis 32 for the hinged anchor 26 too reach is a base area 30 of the recess 28 inclined to the longitudinal direction of the longer leg of the Magnet yoke 12 manufactured.
  • the length 1 (Figure 2) of the coil core 14 from its Contact surface 16 up to its pole face 22 is for the Relay exactly at a height h (FIG. 3) of the pivot axis 32 over a base 34 of the shorter leg of the Magnet yoke 12, on which the coil core 14 with its Bearing surface 16 rests, coordinated.
  • This will make the location the hinged armature 26 in relation to the coil core 14, in particular on the pole face 22 exactly what for an exact function of the relay according to the invention and especially for a matching response Relay of a production series according to the invention indispensable is.
  • a leaf spring 36 extends in an arc around the free end of the longer leg of the magnetic yoke 12 and that in it supported end of the hinged anchor 26 around.
  • the leaf spring 36 is connected to the hinged anchor 26 by means of two rivets 38. With the longer leg of the magnetic yoke 12 is they are connected by a spot weld 40.
  • the leaf spring 36 lifts the hinged anchor 26 from the pole face 22 of the Coil core 14 from. In FIG. 1 there is one on the pole face 22 shown position of the hinged anchor 26, in the it with current-carrying coil 24 due to magnetic force pivots against the spring force of the leaf spring 36.
  • the leaf spring 36 extends over a free end of the Folding anchor 26 out. It serves as a carrier for a mobile Double contact 42 of the electromagnetic Relay.
  • the double contact 42 is located between two fixed contacts 44, 46 of the relay, which with the Base plate 10 are connected via sheet metal tongues 48, 50.
  • the Double contact 42 is in that shown in Figure 1 Switch position of the relay on one of the two fixed Contacts 46 on. In a rest position, not shown of the relay comes the double contact 42 at the other fixed Contact 44 to the system.
  • the two sheet metal tongues 48, 50 are for the electrical connection of the relay through the Base plate 10 passed, which is not in the drawing is visible.
  • the coil 24 is electrically conductive via solder joints 52, 54 connected with two sheet metal tongues 56, 58, which also for electrical connection passed through the base plate 10 are (not visible). In the same way it is Double contact 42 electrically conductive via the leaf spring 36 with a soldering point 60 also through the base plate 10 passed through sheet metal tongue 62.
  • the coil core 14 is exactly the required length 1 has been brought, it is inserted through the coil 24 and riveted to the shorter leg of the magnetic yoke 12. Only the rivet pin 18 of the coil core is used 14 deformed, the length 1 of the coil core 14 changes Not.
  • a distance d between the pivot axis 32 and the Pole surface 22 in the direction of a longitudinal axis 70 of the Coil core 14 is the inventive Manufacturing process exactly and one for each relay Series set the same size, regardless of tolerances of single-part production. This is also the later situation of the hinged armature 26 in relation to the coil core 14 and whose pole face 22 is precisely specified.
