  • the invention relates to a magnet system for a folding armature relay with a U-shaped magnetic yoke, one on a bobbin arranged relay winding, which is one of the U-legs of the magnetic yoke, one on the other U-leg arranged bearing, which has an edge over which is a hinged anchor, and a support element for Support of the hinged anchor at the bearing point.
  • a thing Magnet system is known for example from DE 41 10 660 C2.
  • Folding anchor magnet systems are often used in residual current (FI) or Residual current (DI) circuit breakers used.
  • the pole face of the magnetic yoke, over which the hinged anchor can be tilted is, in particular due to the low resilience soft magnetic material exposed to particular wear.
  • By opening and closing the hinged anchor resulting abrasion or throwing on the tipping edge changes the air gap between the hinged anchor and the magnetic yoke, whereby the response behavior of the magnet system in is not influenced as desired.
  • the wear resistance of a hinged anchor magnet system increase, for example, is the use of galvanic Coatings of magnetic parts. In any case through the wear protection measures of the constructive and manufacturing technology Effort significantly increased.
  • the invention has for its object a magnet system to specify for a hinged armature relay, which for constructive simple construction a particularly low dependency of the tripping behavior of the number of operations.
  • this object is achieved by a magnet system with the features of claim 1.
  • This magnet system is constructed in a generally known manner as a hinged anchor system, essential parts of the system are U-shaped, in cross section preferably rectangular magnetic yoke, one on a coil former arranged, also referred to as excitation coil Relay winding, as well as one in the folded, i.e. closed Condition on both yoke poles of the magnetic yoke Are anchors.
  • the hinged anchor is over the yoke pole of the leg of the magnetic yoke that is not tiltable is surrounded by the relay winding. On the edge, over which the hinged anchor can be tilted, is a support element for wear protection intended.
  • This support element is according to the invention in one piece, preferably as a plastic injection molded part, formed with the bobbin. This is with minimal manufacturing additional effort a very effective Protection of the yoke poles, in particular that of the tilting axis of the Folded anchor assigned yoke pole. An additional separate anchor support member is not required.
  • a bearing surface of the one piece with the bobbin as a combination part trained support element for the hinged anchor is preferably at least approximately parallel to the neighboring one Pole surface of the magnetic yoke arranged. Is located the yoke pole around which the hinged anchor can be tilted, and the storage area, however, preferably not exactly in the same plane. Rather, the storage area provided the hinged anchor is on rests on both pole faces of the legs of the magnetic yoke, in this embodiment of the hinged anchor at least slightly spaced. This means that when the magnet system is triggered, i.e. when lifting the hinged anchor, this first around an edge formed by the leg of the magnetic yoke tilts.
  • the hinged anchor lies on the bearing surface of the support body and tips over in the further movement a second bearing surface formed by the support body.
  • the tilt axis the hinged anchor thus moves during the tilting movement from the arm of the arm surrounded by the excitation coil Magnet yoke away.
  • At the beginning of the tilting movement is therefore from Folding arm formed lever arm between the one carrying the coil Leg of the magnetic yoke and the tilt axis shorter than in a larger opening angle of the hinged anchor.
  • a second in the extension of the hinged anchor Lever arm that protrudes beyond the magnetic yoke and in general is spring loaded at the beginning of the tilting movement relatively long compared to the further movement.
  • the support body comprising the coil body and the support element preferably has an angled shape, either an L or a U shape, with the relay winding one so-called coil leg and surrounds the support element of one aligned essentially parallel to the hinged anchor Longitudinal leg is formed.
  • An additional leg in the case the U-shaped design of the support body is optionally parallel to the longitudinal leg having the support element arranged opposite this.
  • a permanent magnet is special short distance to the hinged anchor can be positioned by the longitudinal leg and, if applicable, the opposite one Thigh a corresponding breakthrough in the area has or have between the legs of the magnetic yoke. Just like the permanent magnet, they also penetrate Yoke leg of the magnetic yoke the longitudinal leg.
  • the coil former is preferably by means of so-called support flanks integrally connected to the support element.
  • support flanks integrally connected to the support element.
  • the support flanks are preferred in the direction of extension of the yoke leg in comparison thickened to the adjacent area of the longitudinal leg, whereby the longitudinal leg of the support body in the area a breakthrough on the support element for the Yoke leg is mechanically reinforced.
  • a holding frame connected to the hinged anchor provided which surrounds the yoke pole surfaces and on the Longitudinal leg of the coil body is attached.
  • the advantage of the invention is in particular that a hinged anchor magnet system supports the hinged anchor on the tilt axis by suitable formation of the coil body is realized without an additional component.
  • FIG 1 and 2 show the structure of a magnet system 1 for a folding armature relay, which a magnetic yoke 2 with a first Yoke leg 3 and a second yoke leg 4 and one Folding anchor 5 includes.
  • the first yoke leg 3 penetrates one surrounded by a relay winding or excitation coil 6
  • Coil leg 7 of a support body 8 which is a plastic injection molded part is made and its shape from the FIG 3 and 4 can be seen in more detail.
  • the magnetic Effect of the relay winding 6 is the magnetic effect of the Permanent magnets 9 opposed.
  • the Folding anchor 5 On the yoke pole surface 12 of the second yoke leg 4 is, in particular 5 shows a tilting edge 13 for the hinged anchor 5 formed.
  • the yoke pole surface 12 is adjacent Bearing surface 14 as part of a support body 8 formed Support element 15 for the hinged anchor 5.
  • the support element 15 is integrally formed on a longitudinal leg 16, which a coil former 17 together with the coil leg 7 forms which carries the excitation coil 6.
  • the the support element 15 and the bobbin 17 is supporting body 8 in the illustrated embodiment as a one-piece plastic injection molded part trained, on which the longitudinal leg 16 a base leg is formed in parallel opposite.
  • the base leg 18 is mechanically connected to a Base plate 19, the support body 1 by means of several Snap fasteners 20 carries and also the articulation the tension spring 10 is used.
  • Deviating from the illustrated embodiment can the coil leg 7 also directly on one Base plate to be attached, in which case the base leg 18 can be omitted. In any case, form the from the Coil leg 7 and the longitudinal leg 16 constructed bobbin 17 and the support element 15 a uniform Support body 8.
  • the support element forming a bearing for the hinged anchor 5 15 has a second tilting edge 21 around which the Folding anchor 5 is tiltable.
  • the second tipping edge 21 is from Folding anchor 5 spaced slightly apart when folded, so that this first when the magnet system 1 responds around the first tilting edge 13 formed by the magnetic yoke 2 rotates.
  • the bearing surface 14 already after a short tilting movement the contacts Folding anchor 5, the bearing surface 14, so that in the further course of movement only the second tilting edge 21 is effective is. This minimizes wear on the yoke pole surface 12.
  • the hinged anchor 5 has a first lever arm 22, 22 ', which from a front edge 23, which when folded Folding anchor 5 in the area of the yoke pole face 11 of the first yoke leg 3 is arranged up to the first tilting edge 13 or extends to the second tipping edge 21. Furthermore points the folding anchor 5 in the extension of the first lever arm 22, 22 ' a second lever arm 24, 24 ', which is different from the first Tilting edge 13 or from the second tilting edge 21 to one Trailing edge 25 extends on which the tension spring 10 engages.
