Definitions

  • the invention relates to a relay with a base, by the bottom of which is defined as a basic level, a central one Anchor, which is part of a magnet system, and one Contact spring attached to a middle section with the anchor is connected so that the contact spring and the armature are common Own bearing axis, and that at its free end Bridge contacts carries.
  • JP 53-6851 An improvement of this construction is disclosed in JP 53-6851.
  • the contact spring points to both Sides of the bearing axis each have two arms that are independent can bend from each other.
  • the Contact spring must therefore be made of a relatively good conductive material exist, but the poorer mechanical properties having.
  • the object of the invention is therefore a relay of the input to create the type mentioned, in which the contact spring if possible is simply shaped, but still has the same contact pressure guaranteed at all contact points, and at the same time one low volume resistance.
  • this object is achieved in that the Contact spring a contact arm on each side of the bearing axis forms, each between the bearing axis and the free End has a torsion bar formed by constrictions.
  • the contact arms have an improved torsional ability, so that the height compensation to the fixed contacts is possible. If the free anchor ends are greatly widened, so that the contact arms are approximately T-shaped, the fixed contacts can be relative are far apart and thus have a high dielectric strength to each other. The current path from a fixed contact to the other runs exclusively over one Bridge contact, so that the material of the contact spring for the Current carrying capacity doesn't matter. For this, therefore uses a material with mechanically favorable properties become.
  • the contact spring in a central area on the side support arms with a fixed relay part are connected. You can both the support arms and the fixed relay parts to the Base floor have vertical surfaces so that when Insert the contact spring the distance between the bridge contacts and fixed contact set and for example can be by welding.
  • Figure 1 shows a relay according to the invention, with a part a housing 22 is cut open.
  • the housing 22 is made from a base 1 and a cap.
  • Inside is the magnet system 20 with a coil 21, a core 23 with pole pieces 24 and a permanent magnet 25 can be seen.
  • This arrangement corresponds to that of a conventional polarized relay.
  • Between the permanent magnet 25 and the base 1 are an anchor 2 and a contact system with a contact spring 3.
  • the contact spring 3 is shown in detail. In of the figure, it is in a central area in a plastic molding 13 embedded. This molded plastic part 13 serves among other things to connect the contact spring 3 with the Armature 2. In about the middle of the contact spring 3 are on the side two support arms 9 are formed. On these support arms 9 is the contact spring 3 on a fixed relay part 10 attached, as detailed in the description of Figure 3 is. In addition, the support arms 9 form a return spring for the contact spring 3 and the armature 2. On the free Contact spring ends 4, bridge contacts 5 are attached. One each the bridge contacts bridges two counter contacts 12, the are embedded in the base 1 (see FIG. 3).
  • the contact spring 3 by, for example, the armature 2 molded support tabs, which are under the contact spring 3 grip, can be improved by tearing the contacts 5 and 12, even if they are welded.
  • Figure 3 shows how the base assembly of an inventive Relay could look like.
  • the base 1 are in one middle area two support pins 10 are provided.
  • the support arms 9 and the carrier pins 10 have mutually parallel Surfaces that are perpendicular to the base plane.
  • This Arrangement has the advantage that the assembly during assembly from contact spring 3 and armature 2 inserted from above and so far can be moved down until the distance between the bridge contacts 5 and the counter contacts 12 one corresponds to the specified dimension.
  • the assembly of contact spring 3 and armature 2 can monostable behavior of the relay can be achieved.
  • the inserted contact spring 3 is with the magnet system not excited a defined bridge contact 5 in contact with the associated Mating contacts 12.
  • connection of the armature 2 with the contact spring 3 is open advantageously realized in that the contact spring 3 plastic molding 13 surrounding in the middle area has two pins 14 on which the armature 2 with corresponding Recesses placed and by deforming the pin 14th is attached.
  • the anchor 2 has one in the central area Curvature 11 upwards. This curvature 11 runs approximately the shape of a half-cylinder and lies on a fixed one Relay part, in this embodiment the permanent magnet 25, so that it can roll on this.
  • This is so far another advantage that the support arms 9 only for the resetting of the contact spring 3 and the armature 2 is responsible are, and not yet additional forces caused by the excited magnet system 20 act on the armature 2, record have to.
  • the anchor is in close contact in this way 2 given with the core arrangement, which is positive affects the efficiency of the magnet system 20.
  • the contact spring 3 from one electrically good conductive material, for example a copper alloy.
  • the carrier pins could 10, with which the support arms 9 of the contact spring 3 are welded are designed as connection elements.
