Definitions

  • Such a relay is for example from DE 34 43 094 Al known.
  • the T-shaped core is attached by extensions the ends of the cross legs that are parallel to the middle leg extend to an E-shape or M-shape.
  • the U-shaped anchor is on with the ends of its longitudinal arms these extensions of the core stored so that its crossbar the working air gap with the free end of the middle leg of the nucleus.
  • This type of anchor bearing on an E-shaped Kern always requires additional bearing elements in the form of a bearing spring that is not just a corresponding one Manufacturing effort with punching and bending, but also during assembly with appropriate adjustment and Riveting or welding operations required. In other ways but such an anchor is not secured in its storage become.
  • there is between the anchor cross leg and the core end has only a relatively small pole area in the working air gap, which are also not easily enlarged can.
  • the aim of the present invention is to provide a relay of the input mentioned type in such a way that with only a few, simply designed and easy to manufacture parts can be assembled in a particularly simple manner, although a reliable function and a high level of responsiveness due to a relatively large pole area in the working air gap are reachable.
  • this goal is achieved in that the Anchor over its crossbar on the free end section of the Longitudinal leg of the core is mounted and that the free ends the anchor longitudinal arms with the free ends of the core cross legs form two parallel working air gaps.
  • the armature bearing and the working air gap reversed so that the U-shaped end of the armature encloses the first coil flange and thus already secured by its arrangement in the longitudinal direction of the coil axis is.
  • the anchor is also secured in other directions in the area of a coil flange by simple constructive Design is possible, a bearing spring is unnecessary with their corresponding manufacturing and assembly costs.
  • the two parallel working air gaps enable a proportionate at the free ends of the anchor large pole face. This pole face can additionally be enlarged that the core cross legs at their ends each with extensions towards the anchor longitudinal arms be provided so that the T-shape of the core is suggestive is expanded into an M-shape or E-shape.
  • the first points Coil flange in a preferred embodiment an approach on, this approach and the anchor interlocking Have projections and / or recesses. Another The anchor can then be secured in its storage by an attached housing cap.
  • the contact spring actuated by the armature is preferred approximately parallel to the coil axis on the opposite side of the armature Side of the coil arranged, the transmission the armature movement on the contact spring by a Slider takes place between the transverse legs of the core on the one hand and the adjacent coil flange on the other is movably guided perpendicular to the coil axis. Also for that Slider can be an approach to the mentioned housing cap an additional Provide leadership.
  • the first coil flange can be attached to the armature bearing also have an extension in the form of a base, which defines a floor level on which the coil axis is vertical.
  • the mentioned, at least one, contact spring and then the at least one counter-contact element conveniently anchored in the base perpendicular to the floor plane, associated pins through the base are guided vertically outwards.
  • the ends of these contact elements are preferably at the second Coil flange at least one stop provided, the rest position the counter-contact element and / or the contact spring Are defined.
  • the movable ends of the anchor arms are preferred a restoring spring force away from the core to a rest position biased, and also is preferably in the central region this longitudinal leg is a fulcrum by one Stop provided on a housing part over which the Return spring force the crossbar of the anchor in its storage presses at the core. This ensures even without a bearing spring that the anchor in its rest position the least possible Has air gap to the core, which makes a good Flow transition and a high sensitivity. Since this return spring force is preferably by the contact spring is applied, the number of individual parts of the relay be kept particularly small.
  • the center of rotation the anchor can be formed by shoulders on the sides the anchor longitudinal arms in connection with a corresponding Rib or groove created on the inside of the housing cap are, so that no additional parts or Assembly operations are required.
  • the relay shown in the drawing consists of a Coil body 1, a T-shaped or approximately M-shaped Core 2, a U-shaped anchor 3, a card-shaped slide 4, a fixed contact spring 5, a movable Contact spring 6, a cap 7 and two anchored in the coil body Coil connector pins 8.
  • the coil former 1 has an axial through opening 11 and a first flange 12 and a second flange 13, between which a winding 14 is applied. Face is an extension 14 for armature mounting on the coil flange 12 in one piece molded on, which merges into a base plate 15. On the approach 14 are limiting pins 16 for the anchor integrally formed, there are also slots in this approach 17 molded through the connecting elements 51 and 61 of the contact springs 5 and 6 through the base plate 15 vertically can be led outside. On the second coil flange 13 is also a stop lug 18 for the fixed contact spring 5 molded.
  • the T-shaped core 2 has a longitudinal leg 21 which in the through opening 11 of the coil body is inserted, and two cross legs 22, at the ends of each side arms 23 are attached parallel to the longitudinal leg 21.
  • the U-shaped Anchor 3 consists of two longitudinal arms 31 and one Crossbar 32, the latter on the free end portion 24th of the core 2 is stored and then in a recess between the first coil flange 12 and the base plate 15 lies. Through the two locking pins 16 of the base approach 14 which engage in corresponding recesses 33 in the armature, he is secured against lateral movements without that his switching movement would be hindered.
  • the free ends of the Longitudinal arms 31 are widened into hook-shaped pole ends 34, which encompass the second coil flange 13 and with the transverse legs 22 and their side arms 23 of the core two parallel Form working air gaps.
  • the fixed contact spring 5 and the movable contact spring 6 are with their connecting elements 51 and 61, which are integrally formed or fastened in a known manner, anchored in the plug-in slots 17 of the base attachment 14.
  • the two contact springs 5 and 6 executed identically and provided with contacts 52 and 62 respectively.
  • the mutual overlap for contacting results through an L-shaped bend on their movable, contact-making End up.
  • the contact springs 5 and 6 are only made of one without bending Cut flat sheet metal and into the coil body plugged in.
  • the mutual offset of their contact Ends only result from the geometry of the coil body or the slider 4.
  • This slider lies between the Coil flange 13 and the transverse legs 22 of the core. He owns a recess 41 through which the longitudinal core leg 21 is put through.
  • After assembling the parts lies the L-shaped bent end portion 63 of the movable contact spring 6 on the stop lug 18 of the bobbin 1 and receives its resting tension.
  • the cap 7 After assembling the individual parts described, the cap 7 put over the relay. It forms with the base plate 15 a closed housing. As can be seen from Figure 4 the cap 7 has a ventilation hole in the area of its upper side 71 on that in an inward protruding approach 72 flows. The latter approach forms an additional guide for the slide 4. As can also be seen from FIG. 4, the armature 3 over the slide 4 by the restoring force the working contact spring 6 biased to its rest position. Lateral shoulders 35 of the anchor abut ribs 72 the cap, thereby forming a pivot point 73 for the anchor becomes. About this fulcrum 73 is due to the leverage the stored end or the crossbar 32 of the anchor in the storage and pressed against the end portion 24 of the core. Thereby reproducible flow transition ratios result in the anchor position and a correspondingly low response excitation.
