Definitions

  • the invention relates to an electromagnetic relay with a spring-elastic tongue anchor arranged inside the coil body, which is mounted on one side and rests with its free end at least one counter pole plate and is attached with its other end to the coil body in the region of a coil flange.
  • a relay of the type mentioned is known for example from DE-A-2 701 230.
  • 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 itself very well 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-B-1 909 940.
  • the tongue anchor is welded with its fastening end to a nose of a connecting pin, the adjustment being possible only by bending this nose using a mechanically attacking tool.
  • 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 the flow guidance is achievable.
  • the tongue anchor of this relay should be adjustable without the intervention of a mechanical tool.
  • the object is achieved in a relay of the type mentioned at the outset in that the tongue anchor in the region of the coil flange serving to fasten it has an additional free-sprung section bent at right angles to the coil axis and lying on the end face in front of the coil flange, and only with a section which springs freely thereon subsequent attachment section is attached to the end face of the coil flange.
  • the resilient tongue anchor Due to the additional freely resilient section, which is arranged perpendicular to the coil axis in front of the coil flange, 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 freely resilient section is also accessible for adjustment with heat pulses, in particular laser pulses, as described, for example, in DE-A-2 918 100. The relay can thus be adjusted without mechanical attack by a tool.
  • the bent, additional free-spring section of the tongue anchor lies in a recess in the coil body.
  • the fastening section can have an extension lying in the same plane, formed at a right angle, which is also arranged on the end face in front of the coil body flange, but, in contrast to the additional freely resilient section, rests on the coil flange.
  • the anchor spring can be fastened by deformed pins of the coil body by means of the fastening section and optionally by means of the extension.
  • the additional freely resilient section of the armature spring is irradiated with heat pulses, in particular with laser pulses.
  • the laser pulses it is expedient for the laser pulses to be irradiated in a targeted manner at specific points in a predetermined matrix, as is already the subject of an older application in accordance with EP-A-O-109 509.
  • 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 a contact surface for a flat, four-pole permanent magnet 9.
  • the tongue anchor is angled at the opposite end of the counter-pole plates and thus has an additional spring section 6b, which lies on the end face 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 of the additional spring section 6b, which is likewise fastened to the coil flange by a pin 10.
  • a connecting pin 6e is formed on the fastening end 6c or 6d, which is used 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 a deformation of the tongue anchor.
  • 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 1, 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 mode of operation of the relay corresponds to that of the relay according to DE-B-2 701 230.
  • 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.
