Definitions

  • the invention relates to an electromagnetic relay with a coil-carrying bobbin with an axial through-opening, with a multiple angled yoke, the first section of which engages in the through-opening of the bobbin, the second section perpendicular to the coil axis on an end face of a first next to the coil up to runs a second coil flange and the third section of which extends parallel to the coil axis next to the coil up to a second coil flange and with an armature which is at least partially arranged in the through-opening of the coil body and which is mounted on the yoke in the region of the second coil flange and in the through-opening forms a working air gap with the first yoke section, with opposing pole faces of the yoke and the armature extending obliquely to the coil axis.
  • Such a structure is known from DE-OS 2 115 004, where an electromagnet with a hinged armature is described.
  • an angular armature is mounted in the central region on the yoke leg in such a way that, in addition to the oblique air gap in the interior of the coil former, it forms a second air gap outside the coil former with the yoke.
  • This is intended to achieve a high sensitivity of the electromagnet.
  • the armature can only actuate a switching element with its short leg, which runs outside the coil body and perpendicular to the coil axis, so that due to the short distance to the bearing point only a small working stroke can be achieved.
  • the object of the invention is to develop a relay of the type mentioned in such a way that, using the working air gap within the coil former, a high sensitivity and a large tightening force is achieved, but that at the same time a relatively large armature stroke for contact actuation can be achieved.
  • the construction, including the contact system should be simple to build and manufacture.
  • this object is achieved in that the armature extends in the longitudinal direction through the entire through opening of the coil body and has an extension for actuating a contact spring in a direction perpendicular to the coil axis with its end opposite the bearing in the region of the first coil flange.
  • the armature thus extends through the entire length of the through opening in the coil body, it being mounted on one coil flange and actuating a contact spring with its free end on the other coil flange.
  • the armature itself can either be rod-shaped in total and be mounted on a fourth yoke leg in the extension of the coil axis.
  • the armature is of an angular design, a second leg running approximately perpendicular to the coil axis in front of the coil flange serving for armature mounting and forming the bearing with the third yoke leg.
  • the entire length of the armature or armature leg penetrating the coil body interior is at least partially wedge-shaped in order to form the aforementioned oblique working air gap with the correspondingly wedge-shaped first yoke leg.
  • the excitation can be chosen to generate a predetermined contact force.
  • the angular pole shoe 10 has a wedge-shaped pole piece 10a, which projects from the coil flange 2 in the axial direction of the coil into the through-opening 8, and a second yoke leg 10b arranged in front of the flange 2 perpendicular to the coil axis.
  • the angle yoke piece 11 connects with a longitudinal leg 11a, which extends as a third yoke leg parallel to the coil axis next to the winding.
  • the angle yoke piece has a cross leg 11 b, which extends as a fourth yoke leg on the front side in front of the flange 3 perpendicular to the coil axis and has a recess 11c, which is only indicated, for receiving and mounting the mounted armature end 9a.
  • This armature end 9a is adapted to the recess 11c in the form of a cutting edge bearing or in some other suitable way so that the armature can make switching movements in the direction of the pole piece 10a with its free end 9b.
  • the armature end 9b is wedge-shaped opposite to the pole piece 10a and forms a working air gap 12 with the pole piece 10a.
  • a contact spring 14 At the free end of the armature 9 there is also an extension 13 which actuates a contact spring 14.
  • This contact spring 14 is arranged with a fastening leg 14a next to the yoke leg 11a and fastened to it, it extends with an actuating leg 14b perpendicular to the coil axis in the direction of the armature extension 13 and forms with its free end 14c a central contact between the two fixed Contact elements 5 and 6 can be switched.
  • On the contact spring leg 14a or on the Winkeljoch Industries 11 sin connecting element 15 for the contact spring 14 is also formed or attached.
  • FIG. 3 shows a somewhat modified design of the armature and the yoke compared to FIG. 2.
  • the armature 19 is of an angular design, a bearing leg 19a extending in front of the coil flange 3 at right angles to the coil axis and being supported on the yoke 20 with the end of this leg 19a.
  • this yoke 20 consists of three legs, namely a wedge-shaped leg 20a as a pole piece, a cross leg 20b, which is arranged on the end face in front of the coil flange 2, and a longitudinal leg 20c, which at its end in the region of the coil flange 3 with the armature leg 19a forms the storage for the anchor.
  • the relay could of course also have a different construction from the examples shown.
  • the contact elements could have a different shape and be arranged differently.
  • a rotation of the magnet system by 90 ° with respect to the coil axis would also be possible, the counter-contact elements having to be designed accordingly differently.
  • the connection elements 15, 17 and 18 led downward in FIG. 1 would be led out to the front (out of the image plane); they would then be visible in FIGS. 2 and 3 on the underside of the relay.
  • the arrangement of the working air gap 12 in the interior of the coil body means that the entire magnetic flux is guided through this working air gap when the relay is excited, so that practically no stray flux components are lost.
  • FIGS. 4 and 5 show the pole face 17 with a radius R on the armature section 9b, whereby the armature touches the pole piece 10a at point 18 when switching.
  • the position of the tightened anchor is indicated by dash-dotted lines.
  • the armature section 9b is also slightly curved in the transverse direction, so that the pole face 17 has the radius r in this direction (FIG. 5).
