Definitions

  • the invention relates to an electromagnetic small relay, in particular to a relay that meets the highest security requirements.
  • the invention relies on an electromagnetic relay of an embodiment with a magnet system consisting of a magnet coil group and an armature pivotably arranged on one end face of the magnet coil and an armature arranged on the opposite end face of the magnet coil actuated by the armature via a connecting web running parallel to the longitudinal axis of the magnet coil and in one Spring bracket summarized spring contact set, wherein the longitudinal axis of the solenoid extends perpendicular to the longitudinal axis of the spring contact set, and the longitudinal axis of the spring contact set perpendicular to a parallel to the longitudinal axis of the solenoid arranged, through which the coil and spring contact connections penetrated bottom plate of the spring bracket.
  • the present invention was dominantly based on the object of constructing a small relay constructed in such a way that 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.
  • the design of such a small relay should be designed so that the individual modules can be plugged together without mechanical connecting elements, while at the same time a complete encapsulation of the small relay should be enough.
  • the magnet system constructed around a flat magnet coil has a coil body flange designed on the magnet armature end side as a coil connection carrier and armature holder and in the form of a flat plug-in unit for plug-in into a cassette-like housing which is completely closed except for one end face, on which the open end opposite side has a spring bracket with spring contacts and connecting lugs, and an actuating web connecting the armature to the changeover contact spring is provided on the outside along a narrow longitudinal side of the cassette-like housing, which, when the magnet system has been inserted into the cassette-like housing, transmits the movements of the armature to the changeover contact spring .
  • the magnet armature-side coil body flange of the magnet system with the integrated outwardly leading coil connections and external lying anchor bracket closes the insertion opening of the cassette-shaped housing in a form-fitting manner.
  • the spring bracket with the corresponding number of spring contacts and connecting lugs is integrated on the front area of the cassette-like housing opposite the insertion opening. wherein the connection lugs are separated from the coil connections, which are preferably likewise led out of the coil body flange in accordance with the cassette length.
  • An actuating web made of insulating material outside the housing connects the free end of the armature on the coil flange to the changeover contact or switch contact spring at the opposite end of the cassette after the magnetic system has been inserted into the cassette.
  • the magnet armature with the actuating web and the spring contact system are housed completely encapsulated by providing a hood which is closed except for a narrow longitudinal side and is adapted to the shape of the cassette and which is shaped and dimensioned for positive locking of the cassette-like housing with inserted magnet system and completely encloses the small relay thus formed.
  • FIG. 2 shows the small relay in a plan 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 Operating web 18 inserted between the free end of the magnet armature 8 and a changeover contact spring 19, and the entire arrangement of magnet system 1 and cassette 14 inserted into a hood 17 adapted to the shape of the cassette 14.
  • FIGS. 1 and 2 only the side of the small relay carrying the connections 4 of the magnetic coil 2 and the connection tabs 13 of the spring contact system is freely accessible.
  • the small relay of the present invention consists of the assemblies magnet system 1 (FIG. 4), cassette 14 with spring contact system (FIG. 5) and hood 17 (FIG. 3). It is of course also possible to use only the assemblies magnet system 1 and cassette 14 as miniature switching relays in receptacles designed corresponding to the hood 17.
  • the magnet system 1 as an assembly comprises a preferably flat magnet coil 2 with a coil body 9, Magnetic core 5, yoke 6 and the magnet armature 8 guided in a holder 7.
  • the magnet armature-side coil flange 10 is designed as a molded part including the armature holder 7 and the coil connection carrier 3 such that after insertion of the magnet system 1 in the direction of the arrow 22 (FIG. 4,5) closes the receiving opening 15 of the cassette 14 in the cassette-like housing 14 of the coil flange 10.
  • the cassette 14 is formed 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 contacts 12 and the changeover contact 19 being inserted or injected into correspondingly shaped recesses.
  • the interior of the cassette 14 is designed to accommodate the magnetic 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 against the corresponding inner sides or an opening-side web of the cassette 14.
  • the end wall 16 separates the magnet system 1 inserted in the interior of the cassette 14 from the spring contact system 12, 19 arranged on the outside.
  • the free end of the changeover or switching contact spring 19 protrudes, as can be seen from FIG. 5, beyond the cassette 14 and, after the magnet system has been introduced into the cassette 14, is connected via an actuating web 18 to the free end of the magnet armature 8 for the transmission of the Anchor movement connected.
  • the actuating web 18 is designed at both ends for a latching with the armature 8 and with the spring 19 accordingly.
  • the magnet armature-side coil flange 10 is designed as a coil connection carrier 3 and also as an armature holder 7 as a molded part.
  • the magnet armature 8 passes through or engages around the magnet yoke 6 and is guided in a recess in the molded part.
  • a hood 17 (FIG. 3) is pushed over the small relay thus completed in the direction of arrow 23, whereby this Hood 17 positively engages the cassette 14 and also the magnet system 1 on the magnet armature side.
  • the top of the cassette 14 comes to rest against cams 21 molded into the hood 17, the hood 17 laterally engages the cassette 14 in a form-fitting manner, and on the end face the hood 17 lies on the surfaces 20 of the magnet system (coil connection carrier 3) and the cassette (spring bracket 11 ) sealing.
  • this small relay according to the invention can be used for all areas of use with high security requirements.
  • the hood 17 can be made of a flexible material, the lower edge of the hood engaging around the cassette 14 and the coil connection carrier 3 by a short distance.
  • the hood can be permanently molded or have ventilation holes or slots that can be created later.
  • the magnet system 1 can be snapped into the cassette 14 or connected by adhesive.
  • the spring contact system can consist of several changeover contact sets with a corresponding expansion of the cassette molding.
