Definitions

  • the invention relates to a small electromagnetic relay according to the preamble of claim 1.
  • EP-A-0 161 473 From EP-A-0 161 473 an electromagnetic small relay of the type mentioned is already known, but the housing is designed as a downwardly open box in which the electrical and mechanical components of the relay are located.
  • the open box known from EP-A-0 161 473 does not represent a housing for inserting the magnet system, because the box open there is formed by the spring bracket, which has no side walls and is not suitable to the extent that a magnet system can be inserted.
  • the spring bracket known from EP-A-0 161 473 merely serves to hold the coil body, essentially by means of a c-shaped attachment, and the armature is also mounted there. The spring bracket also serves to partially guide the actuating web.
  • DE-U-8 433 019 Another small relay of the type mentioned is known from DE-U-8 433 019, an upwardly open box being formed there and being closed off by a cover.
  • the electrical and mechanical components of the relay are arranged in the box.
  • the box, which is open towards the top, according to DE-U-8 433 019 does not represent a housing for inserting a magnet system, because only a vertical wall in connection with a cap-like insulating shoe is shown as the surrounding surface elements, with a leg parallel to the coil between the coil and Ram runs.
  • DE-U-8 433 019 lacks side walls that could accommodate the magnet system between them.
  • the invention has for its object to propose a small relay in which the creepage distances and clearances between potentials of the spring contact set and the magnet system meet the highest requirements, e.g. for underground use.
  • a complete encapsulation of the small relay is to be achieved, which is to be distinguished by a particularly simple assembly.
  • FIG. 2 shows the small relay in a top view of the magnet armature end face along a section line II of FIG. 2.
  • the small relay is assembled ready for operation in the state shown in FIGS. 1 and 2, the magnet system 1 is inserted into the cassette-like housing 14
  • the actuating web 18 is inserted between the free end of the armature 8 and a changeover contact spring 19, and the entire arrangement of the magnet system 1 and the housing 14 is inserted into a hood 17 adapted to the shape of the housing 14.
  • only the side of the small relay carrying the coil connections 4 of the magnet coil 2 and the connection tabs 13 of the spring contact system is freely accessible.
  • the small relay consists of the assemblies magnet system 1 (FIG. 4), housing 14 with spring contact system (FIG. 5) and hood 17 (FIG. 3).
  • the magnet system 1 as an assembly comprises a preferably flat magnetic coil 2 with a coil body 9, magnetic core 5, yoke 6 and the armature 8 guided in an armature holder 7.
  • the magnet armature-side coil flange 10 is, according to the invention, the armature holder 7 and the coil connection carrier 3 enclosing molded part designed so that after 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 designed here with a spring bracket 11 as a molded part or as an additional part to be snapped on or snapped on, or in the case of two separate spring sets, parts, the spring contact set 12 and the switchover contact spring 19 being inserted or injected into appropriately molded-in receptacles.
  • the interior of the housing 14 is designed to accommodate the magnet system 1 in shape and dimension. The magnet system 1 with the yoke 6, the flanges of the coil body 9 and the coil connection carrier 3 is then fixed in the housing 14 against the corresponding inner sides or an opening-side web of the housing 14.
  • the wall 16 separates the magnet system 1 inserted into the interior of the housing 14 from the externally arranged spring contact system 12, 19.
  • the free end of the changeover contact spring 19 protrudes beyond the housing 14, as can be seen in FIG. 5, and, after the magnet system has been introduced into the housing 14, is connected via an actuating web 18 to the free end of the armature 8 for transmitting the armature movement.
  • the actuating web 18 is configured at both ends for a latching with the armature 8 and with the changeover contact spring 19.
  • the coil flange 10 on the magnet armature side is designed in one piece as the coil connection carrier 3 and armature holder 7.
  • the armature 8 passes through the yoke 6 and is guided in a recess in the armature holder 7.
  • a hood 17 (FIG. 3) is pushed over the small relay thus completed in the direction of advance 23, whereby this Hood 17 engages positively around the housing 14 and also on the magnet armature side the magnet system 1.
  • the upper side 14 comes to bear against cams 21 molded into the hood 17, the hood 17 laterally engages the housing 14 in a form-fitting manner, and the hood 17 lies on the end faces sealingly against the surfaces 20 of the magnet system (coil connection carrier 3) and the housing (spring bracket 11) at.
  • the hood 17 is preferably made of a transparent, slightly elastic material.
  • this small relay according to the invention can be used for all areas of application with high security requirements.
  • the hood 17 can be made of a soft, elastic material.
  • the hood can have ventilation holes or slots that are permanently molded or can be created subsequently.
  • the magnet system 1 can be snapped into the housing 14 or connected by adhesive.
  • the spring contact system can consist of several changeover contact sets with a corresponding expansion of the molded cassette part.
