Definitions

  • Such a relay is, for example, in EP 0 197 391 B2 described.
  • the two are movable contact springs on either side of the anchor and in line with this, while the bearing belts themselves in the form of torsion bars in the direction of the axis of rotation extend outside and in the same plane with Connection supports of the base are connected. It means that the length of the torsion bars across the entire width of the relay received.
  • EP 0 691 030 B1 describes a relay of similar construction known in which the bearing tapes in a Anchor longitudinal direction parallel direction from the spring support emerge and just next to the anchor in a to the base level perpendicular direction are bent to parallel to it extending bearing supports to be attached. To in this If the width of the relay is limited, the movable ones Contact springs even arranged below the armature; this however, in turn affects the overall height of the relay out.
  • the object of the present invention is to provide a relay type mentioned at the beginning for the purpose of another To build miniaturization even more compact and at the same time to specify monostable characteristics constructively, whereby a free space gained through the structural asymmetry sensible for the accommodation of coil or Contact connector elements should be used to total to be able to reduce the size of the relay.
  • this task is the relay of type mentioned solved in that of the two Anchor wings the second has a smaller width than the first and the contact spring arrangement in the area of second anchor wing is adapted to its smaller width.
  • the Anchor has two wings of different widths and the however, the space gained in this way is not wasted in the general cuboid housing remains, but the contact spring arms next to the narrower anchor wing - if there are any are present - can also be moved inwards, so that in this area, for example, leads to coil connections can be and in particular the bearing tapes for the Anchors, which also act as connections for the contact springs serve, no additional width of the overall construction need.
  • the pole pieces are attached to the adjusted according to different width anchor wings, so that the pole shoe associated with the second anchor wing has a reduced width with a correspondingly smaller Pole surface as the pole shoe facing the first armature wing having.
  • the relay shown in Figures 1 to 6 consists of two large assemblies, which are shown in Figure 1, namely from a magnet assembly 1 and a base assembly 2, the to be plugged together and then the full relay result.
  • the magnet assembly 1 is initially with a Plastic coating 3 ( Figure 2) overmolded, so that by Put one on top of the other and stick together to form a tight housing becomes.
  • the magnet assembly 1 has as a carrier 3 a bobbin 10 with two flanges 11 and 12, between which two webs 13 as winding supports run.
  • a winding 15 ( Figure 1) is then on through the webs 13 and Core 14 formed winding carrier applied.
  • In the flange 11 two coil pins 16 are also anchored; this extend perpendicular to a base plane 4 next to internally offset base sections 49 of the base assembly 2 to the bottom of the finished relay.
  • the core 14 forms with U-shaped bent ends Pole shoes 17 and 18, which are still closed descriptive anchor form pole faces 17a and 18a. It is the first pole piece 17 is made wider than the second Pole shoe 18 so that the one formed by the first pole shoe Pole area 17a is also larger than the pole area 18a of the second pole piece. Between the two pole pieces 17 and 18 a permanent magnet 20 is inserted (see also FIG. 4), which is shown in FIG Adaptation to the different width pole shoes 17 and 18 also has two sections of different widths, namely a first magnet section 21 with a larger width and a second magnet section 22 having a smaller width.
  • the permanent magnet 20 is lengthwise in a known manner magnetized three-pole, so that it has two at both ends Poles of the same name, in the example South Pole S and in the middle an opposite pole, in the example a north pole N, having. Accordingly, it generates in the two pole pieces 17 and 18 also South Pole S, while one is still closed descriptive anchor 24 below the central north pole N is stored.
  • This anchor 24 is a rocker anchor with two anchor wings 25 and 26, between which he has a roof shape has embossed middle section 27 with which it is below of the center pole N of the permanent magnet 20 (in compliance with a more or less large air gap) stored or without special storage pivoted about an axis of rotation 6 is.
  • the anchor wing 25 has the same width as that Pole shoe 17 with which it has a first working air gap 7 forms; the anchor wing 26 is also reduced in width like the pole piece 18 with which he makes a second Working air gap forms.
  • a contact spring assembly 28 connected to the armature has a plastic spring support 29, the two separate contact springs 30 and 31 through Injection molding connects.
  • Each of the two contact springs is made from two opposite to each other from the wrapping of the Spring support 29 emerging spring arms, namely the Contact spring 30 from a first spring arm 32 and one for this laterally offset second spring arm 33, the second Contact spring 31 from a first spring arm 34 and a second spring arm 35 also offset laterally inwards.
  • each contact spring has a bearing band 36 or 37, which is aligned with the first spring arm 32 or 34, however opposite to this, from the spring support 29 emerges and into a plane perpendicular to the base plane is bent at the top where it has a fastening tab 36a or 37a on a connection support 46a or 47a of the base, for example, by welding.
  • Spring arms 32,33,34 and 35 is at the free end Double contact split fork-like and on everyone Provide the fork end with a contact piece in the usual way.
  • the spring support 29 also forms in the area between the two contact springs 30 and 31 a trough-shaped Recording 38 for the anchor 24.
  • This recording 38 is with all around raised insulating walls 39, so that too sufficient insulation for very small distances between the contact springs 30 and 31 on the one hand and the armature 24 on the other hand is guaranteed.
  • the anchor receptacle 38 is with their internal dimensions exactly to the contour of the Adjusted anchor so that in the area of the narrower Anchor wing 26 also insulated the insulating walls 39 to the inside and the inward arrangement of the second Allow spring arms 33 and 35. That way created laterally by the spring arms 33 and 35 for the arrangement of the coil pins 16.
  • bearing belts 36 and 37 in addition to the spring arms 33 and 35 can be cut from the same sheet metal.
  • the rest are both contact springs with their spring arms and prefabricated the bearing tab from a common board and to form the spring assembly 28 with plastic molded.
  • the anchor 24 is in the receptacle 38 corresponding design of the side walls 39 form-fitting held.
  • the spring assembly 28 connected to the armature is shown in FIG. 6 once again shown completely how to use a base 40 too the base assembly is assembled according to Figure 1.
  • the Base 40 has a flat bottom 41, the underside of which defines the basic level 4.
  • In the base 40 are made of one PCB cut through contact connecting tracks Overmolding anchored with plastic. In the present example it is fixed contact carrier 42,43,44 and 45, the below the movable spring arms 32, 33, 34 and 35 lie and wear fixed contact pieces at their ends.
  • connection supports 46a and 47a There are also two contact spring terminals 46 and 47 in the Anchored base, which is angled vertically upwards Form connection supports 46a and 47a. At these connection supports 46a and 47a become the mounting tabs during assembly 36a and 37a welded. Since the mounting surfaces between the connection supports and the fastening tabs perpendicular to The bearing tapes can run with their base level Connection tabs are aligned in height so that the Contact springs the correct contact distance to the respective Take fixed contact carriers or their contact pieces; to the mounting tabs are the appropriate orientation welded.
  • the dimensioning of the bearing belts 36 and 37 allows a desired spring rate regardless of the thickness of the Adjust contact springs.
  • the vertical connection of the Bearing tapes also results in a high impact resistance of the Relay.
  • the contact connection elements 42 anchored in the base to 47 also each have a downward bent Pin 42a to 45a or 46b and 47b.
  • the connector pins can also be at right angles to Be bent for the purpose of surface mounting.
  • the base side walls 48 there are arranged on the base side walls 48 so that the encapsulated magnetic system clamped between them.
  • the Coil flange 11 are also downward projections 11a with the coil connecting pins 16 guided in them dimensioned that they have inwardly offset base sections 49 grab and also contribute to the fixation.
  • the air gap between the middle section 27 of the armature and the center pole of the permanent magnet 20 (on approximately 0). Then the remaining column between the assemblies of the Relay system sealed with cast resin.
  • a subsequent one Magnetic alignment of the permanent magnet 20 ensures that the relay responds at a desired voltage or back falls.
