Definitions

  • Such a relay is for example from EP 0 211 446 B1 known.
  • a tension spring serves as the return spring which between the two, via your storage location in the yoke extended anchors is arranged. This relay serves to safely interrupt a load circuit. Through the Series connection of the two anchors and thus the two contact points the load circuit is interrupted even if a contact point is welded.
  • Another generic relay is from the US-PS 2,353,377 known. With this relay, the two point Contact springs and the two counter-contact elements each a common connection. The relay is used for safe Closing a load circuit even with strong vibrations and accelerating, such as when landing an airplane, which is achieved by connecting the two anchors in parallel becomes.
  • FIGS. 8 and 9 of US 2,353,377 A second embodiment is shown in FIGS. 8 and 9 of US 2,353,377 shown, in which two contact springs per anchor are arranged. With the relay of this embodiment two load circuits can thus be safely connected.
  • the anchors are also reset using a tension spring, which extended beyond the storage points Anchor attacks.
  • the invention has for its object the generic To further develop relays such that two brushless DC motors each with three arranged in a star connection Windings in the star center through the electromagnetic Relays connected or separated from each other can be.
  • the object is achieved in that Generic relay described above, the contact spring each provided with a connection and two contact pieces is and each contact piece with a separate connector arranged counter-contact element cooperates.
  • the relay thus has two connections on the contact springs and four connections, each with the mating contact elements connected. About these six Connections can therefore be made using a single relay partial windings of the two motors connected in parallel be connected or separated at the star center.
  • the contact spring is preferably E-shaped, wherein the contact pieces at the free ends of the outer legs are arranged and the free end of the middle leg is set and as a return spring means for the respective Serves anchor. Due to the E-shaped design of the contact spring a compact and inexpensive construction is achieved. This is further promoted by the fact that the free fixed end of the middle leg of the contact spring with the connection of the contact spring is connected.
  • the anchor is also E-shaped, the legs of the anchor essentially under the legs of the E-shaped contact spring are arranged.
  • This has the advantage that to achieve a maximum and equal contact force of the double contacts Manufacturing-related tolerances through an overstroke adjustment of all four contacts arranged on the contact spring in can be easily eliminated.
  • the anchor preferably has notches at the bending points to get a defined target bending point.
  • the connections on the contact springs as well two connections on the mating contact elements conductive connected with each other. Due to the parallel connection redundancy and thus a secure connection or Separate the two star centers of the three Windings of the motors connected in parallel.
  • the relay shown in Figures 1 to 7 consists of a bobbin 1 with two side symmetrical flanges 2A and 2B, between which the bobbin 1 with a Winding 3 is provided.
  • As connections for the winding 3 are round or in the side flanges 2A and 2B injected rectangular wires 4A and 4B.
  • the coil former 1 is hollow in the middle and is axially continuous round or rectangular core 5.
  • On the bobbin 1, a yoke 6 is arranged parallel to the axis of the core 5, at each of its two end faces movable armature 7A and 7B is mounted.
  • the yoke 6 serves for flux guidance in the magnetic circuit and is designed as a flat sheet and to provide holes on four pins be plugged onto the flanges 2A and 2B of the coil former 1.
  • the connection is made, for example, by hot stamping the cone.
  • the core 5 and the yoke 6 have almost the same length.
  • the end faces of the core 5 form the pole faces 5A and 5B for the two anchors 7A and 7B.
  • the core 5 can either be a pluggable part without enlarged pole faces 5A, 5B, as shown in Figure 4, or as one of the bobbin 1 overmolded part with enlarged pole faces 5A 'and 5B ', as shown in FIG. 5.
  • the two anchors 7A and 7B are flat and essentially E-shaped trained and thus consist of a base 70, two outer legs 71 and 73 and a middle leg 72.
  • the contact spring 8A or 8B is at its base 80 via two riveted or welded connections 9 connected to the base 70 of the armature 7A or 7B.
  • the outer legs 81 and 83 of the contact spring 8A and 8B respectively stand over the outer free ends of the outer legs 71 and 73 of the armatures 7A and 7B, respectively, and carry in this protruding area a contact piece 10A to 10D.
  • This four contact pieces 10A to 10D are when the coil is energized by the armature 7A or 7B against four mating contacts 11A to 11d pressed, which each on separately formed connections 12A to 12D are provided, each in grooves the flanges 2A, 2B of the bobbin 1 are guided.
  • the Contacts 10A to 10D and the counter contacts 11A to 11D designed as riveted or welded contacts and thus to each other arranged that the contact pieces 11A to 11D against the spring force of the contact spring 8A or 8B the counter contacts 11A to 11D are pressed.
  • the two E-shaped anchors 7A and 7B serve only the middle legs 72 and in each case the middle area the base 70 for flow guidance. Since the outer legs 81 and 83 of the contact spring 8A or 8B on the outer legs 71 and 73 of the armatures 7A and 7B, respectively, are used to increase the overstroke the outer legs 71, 73 the anchor inwards, that means towards the spool or to reduce the overstroke turned outwards. In order to bend the outer legs 71 or 73 of the armatures 7A or 7B to defined predetermined bending points are obtained between the base 70 and the outer Legs 71 and 73 notches 74 are provided.
  • the middle leg serves as the return spring 82 of the contact spring 8A or 8B.
  • This middle leg 82 is over the free end of the middle leg 72 of the anchor 7A and 7B extended and each on another Connection 13A or 13B fixed.
  • the middle leg 82 the E-shaped spring 8A and 8B is thus used for Power supply and for resetting the armature.
  • the connections 13A and 13B are identical to the terminals 12A to 12D formed and also in grooves of the flanges 2A, 2B of the coil body 1 led to a low-tolerance structure of the relay to achieve.
