Definitions

  • the invention relates to an electromagnetic trigger according to the preamble of Claim 1.
  • a trigger is from the EP 0 501 844 B1 is known.
  • An electromagnetic release of a motor protection switch usually consists of a yoke, a bobbin of a coil, an armature and a shackle spring.
  • Current flows through the coil and is monitored by the switching device and exerts a magnetic force on the armature, which is guided in the coil body.
  • the shackle spring By means of the shackle spring, the armature is prevented from moving even with small currents sets in motion. Only when the magnetic force on the anchor, the counterforce of the If the cage spring exceeds what is the case with a certain overcurrent, the anchor becomes pulled into the coil.
  • This movement of the armature is in a motor protection switch usually used to connect the contact bridge of the switchgear directly to open and to unlatch the key switch, in the latter case a permanent opening of the contact is achieved, whereas in the former case the contact bridge returns to the closed position after a short time.
  • the shackle spring is designed as a leg spring.
  • One leg of the spring is supported on the bobbin, whereas the other engages in an annular groove in the anchor.
  • the armature moves into the coil body one leg of the spring is moved in the same direction, which causes the ankle spring to bend in a direction perpendicular to the first movement moves. This bend then presses a slide that finally the switch lock is released.
  • the shackle spring is complicated and in the second case is one high number of parts available.
  • the object of the invention is an electromagnetic trigger of the aforementioned To create art that consists of a few simple parts and beyond enables easy assembly.
  • the armature then has at its end protruding from the coil in a manner known per se Way a circumferential groove in which the end of the compression spring loaded under pressure intervenes and ties the armature up to a certain value of an overcurrent.
  • the turn of the cage spring facing the anchor is preferably deformed in such a way that that it engages positively in the groove.
  • This deformation can then be used even further in such a way that it is radial Forms the lead when tightening the anchor on a latching point of the Switching device opens to unlatch it.
  • the partial housing 10 is of two parallel side walls 11 and 12 bounded and has partitions 13 and 14 through the chambers 15, 16 and 17 are formed, in which an electromagnetic trigger and Like. Are, the structure of the electromagnetic release with reference to FIG. 2nd and 3 will be described.
  • each of the two side walls 11 and 12 there is a bearing 18 and 19 for one Swivel shaft 20, on which arms 21, 22 and 23 are formed, with the in no closer as shown, a latching point can be opened in a key switch can.
  • an electromagnetic trigger 30 with a yoke 31, which is approximately one U-shape with two legs 32 and 33 forms; perpendicular to the two parallel ones Legs 32 has a coil 34 which surrounds an armature 35.
  • the anchor 35 has its end protruding from the coil 34 has a circumferential groove 36, whereby a Mushroom head 37 is formed.
  • the armature 35 is surrounded by a shackle spring 38 which is shown in more detail in FIG. 2 is. It comprises a plurality of circular, helically associated turns 39, whose last turn 40 is oval-shaped and has two legs 41 and 42, that run perpendicular to the spring axis and span a plane that also runs perpendicular to the axis.
  • the turn 40 with the two legs 41 and 42 forms a protrusion 43 that radially surrounds the coil spring 38 surmounted.
  • the distance D between the two legs 42, 42 is such that the two Lather legs 41, 42 into the interior of groove 36; it corresponds approximately to the inside diameter the groove 36.
  • the spring 38 has a positive fit with the end anchor 35 is connected; with its end facing the coil 34 lies on the yoke web or yoke leg 32. As soon as the armature 35 inside the coil 34 is drawn in, with a certain tightening force at a certain overcurrent required and must be exceeded, then the spring 38 is compressed by the mushroom 37.
  • Extensions 24, 25 and 26 are integrally formed on the arms 21, 22 and 23. On the extension 24 pushes the projection 43 when tightening the armature, causing the shaft 20 in a clockwise direction is pivoted and so opens a switch lock, not shown.
  • Fig. 1 only a magnet system is shown; the two chambers 16 and 17 also have such electromagnetic triggers.
  • Fig. 3 shows that the yoke web or yoke leg 32 of a guide housing 44 is surrounded, on which a rod 45 is formed, which is parallel to the anchor axis in The direction of the non-triggered position of the armature 35 protrudes.
  • the free end of the Rod 45 has a nose 46 which is used for mounting and guiding the Spring 38 and thus also for guiding and holding the armature 35 during the Assembly serves.
  • Fig. 1 Observer facing upwards, another housing part on which the armature 35th press the coil spring a certain amount into the coil.
