Definitions

  • the invention relates to an electromagnetic relay with a spring-elastic tongue anchor arranged on one side within a coil body, the free end of which faces at least one opposing pole plate and is attached with its other end to the coil body in the region of a coil flange.
  • the invention also relates to a method for adjusting such a relay.
  • a relay of the type mentioned is known for example from DE-AS 27 01 230.
  • the resilient tongue anchor is attached at one end to a carrier, which forms an adjusting plate that can be permanently adjusted by an external magnetic field, so as to adjust the position of the tongue anchor.
  • This structure has proven its worth because of the adjustability in the fully encapsulated state, but the space required for the adjusting plate must be taken into account in the construction, as a result of which the coil diameter cannot be made arbitrarily small.
  • the free spring length of the tongue anchor is limited by the length of the coil body interior in the known relay.
  • a relay with a spring-elastic tongue anchor, which is arranged within the coil former, is also known, for example, from DE-AS 19 09 940.
  • the tongue anchor is welded with its fastening end to a nose of a connecting pin, the adjustment only by bending this nose by means of a mechanical attacking tool is possible.
  • the free spring length is limited by the length of the coil body tube.
  • the object of the invention is to design a relay of the type mentioned in such a way that the free spring length of the tongue anchor is not limited to the length of the coil body interior, so that even with a very small construction and a correspondingly short coil body, a soft spring characteristic of the armature with a sufficiently large one Cross-section for flow guidance is achievable.
  • the tongue anchor of this relay should be adjustable without the intervention of a mechanical tool.
  • the invention is intended to provide a method for adjusting this relay.
  • the object is achieved in a relay of the type mentioned above in that the tongue anchor in the area of the coil flange serving for its attachment has a bent at right angles to the coil axis, lying in front of the coil flange and only with the end of this additional spring section on the End face of the coil flange is attached.
  • the resilient tongue anchor can be made softer with the same cross-section and with the same coil length, so that even lower forces of a permanent magnet or excitation are sufficient for switching. This makes the relay more sensitive.
  • Another advantage of the tongue anchor design according to the invention is that the additional spring section is also accessible for adjustment with heat pulses, in particular laser pulses, as described, for example, in DE-OS 29 18 100 is written. The relay can thus be adjusted without mechanical attack by a tool.
  • the bent additional spring section of the tongue anchor lies in a recess in the coil body.
  • the tongue anchor can have an additionally formed fastening tab, which is also arranged on the end face in front of the coil body flange, but, in contrast to the additional spring section, rests on the coil flange.
  • the anchor spring can be fastened by deformed fastening pins of the coil body at the end of the additional spring section and, if appropriate, on the additional fastening tab.
  • the additional spring section of the armature spring is irradiated with heat pulses, in particular with laser pulses. It is expedient for the laser pulses to be irradiated specifically at specific points in a given matrix.
  • Fig. 1 to 3 a relay designed according to the invention in three different sectional views.
  • the relay according to the invention shown in the drawing has a coil body 1 with a winding 2, which is limited by the coil flanges 3 and 4.
  • a spring-elastic tongue anchor 6 is arranged in the coil interior 5, and its free end 6a can be moved between two counter-pole plates 7 and 8.
  • the opposing pole plates 7 and 8 are angled and, with their sections 7a and 8a arranged in one plane, form one Contact surface for a flat, four-pole permanent magnet 9.
  • the tongue anchor is angled at the end opposite the counter-pole plates and thus has an additional spring section 6b, which is located in front of the coil flange 3 and thus extends the entire free spring length of the tongue anchor 6.
  • the end 6c of the additional spring section 6b lies on the end face of the coil flange 3 and is fastened with a thermoformed pin 10 of the coil body.
  • a further fastening section 6d is integrally formed on the side from the additional spring section 6b, which is also fastened to the coil flange by a pin 10.
  • End 6c or 6d formed a connecting pin 6e, which serves for electrical contacting of the tongue anchor 6, which also serves as a central contact spring.
  • the coil flange 3 has a recess 3a.
  • the additional spring section 6b of the tongue anchor 6 is irradiated with laser pulses which strike it at points 11 and each cause the tongue anchor to be deformed.
  • the free anchor end 6a is adjusted in the direction of arrow 13. If the armature is to be adjusted in the opposite direction, this could be done, for example, by mechanical pressure at point 14 or by an additional mechanical pressure at point 14 with simultaneous irradiation with laser pulses.
  • the recess 3a of the coil former can be temporarily covered by a film 15, while the opening of the coil former on the opposite side is pre-sealed by a film 16 inserted between the pole plate sections 7a and 8a on the one hand and the permanent magnets 9 on the other.
  • the cavities can then be poured out with casting resin without it being able to penetrate into the interior 5.
  • the operation of the relay corresponds to that already given in the known relay according to DE-AS 27 01 230.
  • the ferromagnetic cap 17 serves to guide the flux of the permanent magnetic circuit as well as the excitation circuit.
  • the opposing pole plates 7 and 8 are provided in the usual way with connecting pins 7b and 8b.
  • coil connecting pins 18 are embedded in the coil body 1 in a known manner.
