Definitions

  • the invention relates to an electromagnetic load relay with a coil with a winding applied to a coil former between end flanges, a core axially arranged inside the winding, a yoke arranged outside the winding, which is connected to one end of the core, and a bearing on the yoke the free core end forming an armature working gap and with at least one switch-actuable switch contact which is connected via a current supply element to a connection element, the current supply element being passed at least once through the excitation flux circuit formed from the yoke, core and armature.
  • the object of the invention is therefore to develop a relay of the type mentioned in such a way that additional excitation can be generated in the same direction as the excitation circuit by the load circuit, but at the same time an intervention in the actual winding space is avoided and reliable insulation of the current supply of the load circuit is ensured.
  • this object is achieved in that the current supply element is connected on one side of the coil to a connecting element, is guided through a transverse bore in a coil flange to the other side of the coil and is connected from there to the switching contact.
  • the desired additional excitation for the relay is generated without an additional element having to be installed in the actual winding space.
  • the guidance in the coil body flange also ensures good insulation between the load circuit and the actual excitation circuit.
  • the additional excitation which is generated by the current supply element guided through the flange, keeps the relay in the tightened state after the contact current has been switched on, so that even a brief interruption of the current due to the aforementioned bouncing switching on no longer causes the relay to drop out.
  • this additional excitation promotes a rapid pulling through of the relay armature when switched on, so that high contact forces are reached quickly and the erosion of the contact material is kept within limits.
  • the holding effect due to the additional excitation is so small that there is hardly any adverse effect when the relay drops out. Appropriate dimensioning can also determine how high the additional excitation should be. If necessary, it is also possible to split the power supply and lead only a part through the cross hole in the yoke.
  • the additional excitation described is mainly used for relays in which the armature and the yoke are traversed by the contact current.
  • To make the additional excitation possible To make high, you can also increase the resistance across the armature and the yoke, for example, by not using the contact spring made of a good conductive material, but of poorly conductive spring material, such as. B. steel. This has the additional advantage that materials with better spring properties and higher fatigue strength can be used, these steel materials are usually also less expensive than the otherwise required, highly conductive copper alloys.
  • the contact current is expediently guided through a strand which is welded directly onto the rivet head of the contact and runs through the transverse bore in the coil flange.
  • the relay shown in Figures 1 and 2 has a known basic structure with a coil body 1 as a supporting element, on which a winding 4 is applied between two flanges 2 and 3.
  • a core 5 is mounted axially within the coil.
  • This core is connected at one end to an angular yoke 6, namely to the vertical leg 6a, while the horizontal leg 6b extends above the coil.
  • a flat anchor 7 is mounted, which is fastened to the yoke via an anchor spring 8.
  • the extension of this armature spring 8 serves as a contact spring 8a and carries at its free end a contact piece 9 which is opposite a fixed mating contact piece 10.
  • This mating contact piece 10 is fastened to a connecting element 10a, which is designed as a flat plug.
  • a flat plug 6c designed as an extension of the yoke leg 6a serves as the connecting element for the contact piece 9 on the contact spring 8a.
  • coil connection elements plug elements 11 and 12 are also anchored in the base body.
  • a stranded wire 13 is also provided, which is connected at one end directly to the flat plug 6c and to the other end is welded directly onto the contact piece 9.
  • This copper strand 13 can, for example, carry up to 90% of the current, in particular when the armature spring 8 is made of relatively poorly conductive metal, such as spring steel.
  • this stranded wire 13 is guided through a transverse bore 3 a of the bobbin flange 3.
  • This transverse bore runs in the horizontal direction with the relay in the normal installation position, namely between the coil core 5 and the yoke leg 6b.
  • the polarity must be selected accordingly when the load circuit is connected so that there is a positive superposition of the additional excitation with the coil excitation.
