Definitions

  • the invention relates to an electromagnetic Small relay according to the preamble of the claim 1.
  • EP-A-0 161 473 is already an electromagnetic one Known small relays of the type mentioned, but the case as down open box is formed, in which the electrical and mechanical components of the Relays.
  • the one known from EP-A-0 161 473 open box does not represent a housing to insert the magnet system, because the box open there is formed by the spring trestle, that has no side walls and so far it is not suitable for a magnet system to be inserted can be.
  • the one from EP-A-0 161 473 known spring bracket is used only, essentially by means of a c-shaped approach, for mounting of the bobbin, and there is also the Anchors stored. The spring bracket is also used for partial Management of the actuation bridge.
  • DE-U-8 433 019 Another small relay of the type mentioned is known from DE-U-8 433 019, where a open top box is formed by a lid is completed. In the box are the electrical and mechanical components of the relay arranged.
  • the top open box according to DE-U-8 433 019 however, no housing for inserting a magnet system because as enclosing surface elements are only connected to a vertical wall with a cap-like insulating shoe set out, with a leg parallel to the coil runs between coil and plunger.
  • the DE-U-8 433 019 so far there are no side walls record the magnet system between them could.
  • the invention is based on the object Propose small relay in which the creep and Clearances between potentials of the spring contact set and the highest magnet system Requirements, e.g. for underground use. It is said to be a complete encapsulation of the Small relay can be achieved by a particularly simple assembly.
  • FIG. 1 and 2 is a basic embodiment of the small relay partially cut shown.
  • Figure 2 shows the small relay here in a top view of the magnet armature-side end face along a section line 1-1 of Figure 2.
  • Das Small relay is in the in Figures 1 and 2 assembled state ready for use, the magnet system 1 is in the cassette-like housing 14 inserted, an actuating web 18 is between the free end of the armature 8 and one Changeover contact spring 19 used, and the entire Arrangement of magnet system 1 and housing 14 is in one of the shape of the housing 14 adapted hood 17 inserted.
  • the small relay consists of the modules Magnet system 1 (Fig.4), housing 14 with Spring contact system (Fig.5) and hood 17 (Fig.3).
  • the magnet system 1 comprises as an assembly a preferably flat magnetic coil 2 with bobbin 9, magnetic core 5, yoke 6 and the anchor 8 guided in an anchor holder 7.
  • the magnet armature-side coil flange 10 is in accordance with the invention as an the anchor bracket 7 and the molded part including the coil connection carrier 3 trained so that after the insertion of the Magnet system 1 in the direction of arrow 22 (Fig. 4.5) in the cassette-like housing 14 of the coil flange 10 closes the end face 15 of the housing 14.
  • the housing 14 is here with a spring bracket 11 as a molded part or as an additional on or part to be locked, or in the case of two separate parts Spring sets, parts formed, the spring contact set 12 and the switch contact spring 19 in appropriately molded receptacles used or are injected.
  • the interior of the Housing 14 is for receiving the magnet system 1 in shape and dimension accordingly designed. Then in the housing 14 Magnet system 1 with the yoke 6, the flanges of the bobbin 9 and the coil connection carrier 3 against the corresponding inside pages or abutting an opening-side web of the housing 14 fixed.
  • the wall 16 separates that into the interior of the Housing 14 inserted magnet system 1 from externally arranged spring contact system 12, 19.
  • the free end of the changeover contact spring 19 protrudes, as can be seen from FIG Housing 14 addition, and will after insertion of the magnet system in the housing 14 via a Actuator bar 18 with the free end of the armature 8 for the transmission of the anchor movement connected.
  • the actuating web 18 is at both ends for locking with the anchor 8 and with the Switchover contact spring 19 designed accordingly.
  • the coil flange on the magnet armature side 10 as a coil connection carrier 3 and anchor bracket 7 formed in one piece.
  • the anchor 8 penetrates the yoke 6 and is in a recess the anchor bracket 7 out.
  • the top 14 comes against in the hood 17 molded-in cams 21 on the side encloses the hood 17 form-fitting the housing 14, and the face of the hood 17 lies on the surfaces 20 of the magnet system (Coil connection carrier 3) and the housing (Spring bracket 11) sealing.
  • the hood 17 consist of a soft elastic material.
  • the hood can be permanently molded or ventilation holes that can be created subsequently or have slits.
  • the magnet system 1 can the housing 14 snapping or by gluing be connected. Furthermore, the spring contact system from several changeover contact sets with a corresponding expansion of the cassette molding consist.
