Definitions

  • the invention relates to a relay according to the preamble of claim 1.
  • a relay has become known in various forms; All embodiments have in common that the core and the yoke form two different parts, which are therefore manufactured separately from one another and which are only connected to one another before the relay is assembled.
  • the core is connected to the associated yoke via a rivet connection.
  • this has the disadvantage that the connection between the core and the yoke in the area of the rivet connection can never be completely smooth, and this results in a slight air gap which increases the magnetic resistance in the flux circuit.
  • the invention has for its object to develop a relay of the type mentioned so that the resistance in the magnetic flux circuit, consisting of core, yoke and armature, is further reduced.
  • the invention is characterized in that the yoke and core consist of a one-piece U-shaped part.
  • the yoke and core consist of a coherent, identical part, as a result of which the air gap described above, which can form in the connecting gap in the case of a two-part part, is avoided. Due to the one-piece construction of the yoke and core, the resistance in the magnetic flux circuit is substantially reduced and, consequently, the efficiency of the relay is improved.
  • the core consists of a round-profiled metal part which merges on one side into a flat-profiled connecting flange, which in turn merges into a flat-profiled yoke.
  • a round-profiled metal part which merges on one side into a flat-profiled connecting flange, which in turn merges into a flat-profiled yoke.
  • Such a part is produced from a round material, the round-profiled core being produced by die-forming this round material. After this shaping, the flat material is bent in a U-shaped manner, after which the round-profiled core is opposite a yoke formed as a flat material.
  • the yoke and core consist of a stamped part and this time the core is not flat-profiled by die forming, but only a multiple bending process takes place, after completion of which both the yoke and the core are made of a rectangularly profiled material (flat material ) are formed.
  • the core which is still made of a flat material, is round-profiled by die forming.
  • Fig. 1 only the magnet system of a relay is shown, which in a conventional manner consists of a coil, the coil carrier has a central recess 2 into which a round-profiled core 7 is inserted.
  • the round-profiled core 7 opens as shown in FIGS. 1, 2 and 3 in a rectangular profiled connecting flange 8, which in turn is bent through 90 degrees and opens into a yoke 6 with a rectangular profile.
  • the armature 4 is pivotally mounted on the end face of the yoke 6 according to FIG. 1 and at its free, pivotable end there is an actuating pin 5 which actuates the contacts of the relay, which are not shown.
  • the opposite side of the armature 4 lies as flush as possible on the end face 3 of the core 7.
  • 1 - 3 show that the core and yoke consist of a one-piece part which is bent in a U-shape.
  • a first bending edge 22 is located between the core 7 and the connecting flange 8, while a second bending edge 21 is located between the connecting flange 8 and the yoke 6.
  • FIG. 4 shows an embodiment of the core and yoke that is improved compared to FIG. 1, because the end face 3 of the core 7 near the anchor has an enlarged area there, so that the contact area with the armature 4 is enlarged.
  • a head part 10 is pushed onto the end face of the core 7, which is provided with an annular flange 12 and has an inner recess which is pressed onto the core 7 precisely flush.
  • the end face 11 of the head part 10 is enlarged compared to the original end face 3 of the core 7.
  • the head part 10 is integrally connected to the core 7 by inserting the core into the recess 2 of the coil 1 in the same manner as the head part 10 shows , mushroom-shaped, so that the head part 10 is integrally connected to the core 7.
  • 5-9 show the second embodiment of a one-piece connection between a core 27 and a yoke 26.
  • this embodiment is an angular stamped part 13, which consists of a flat material.
  • a lower bracket 14 is connected in one piece to another bracket 15 at an angle of 90 degrees.
  • a recess 18 is provided which extends approximately diagonally to the outer edge approximately to the center of the stamped part 13.
  • this part is first bent in the region of the bending edge 17, so that the tab 15 protrudes vertically from the plane of the drawing according to FIG. 6, as shown in FIG. 6.
  • the tab 15 is thus connected to the lower tab via a connecting flange 20, the connecting flange being formed by the corner between the tab 14 and the tab 15, which was divided by the recess 18.
  • 5 also shows that a further recess 19 can be provided in the area of the bending edge 17 in order to facilitate bending in the area of the bending edge 17 during the transition from FIG. 5 to FIG. 6.
  • a U-shaped part results from a flat material, wherein in a further process step the core 27 consisting of the flat material can still be profiled round by die forming.
