Definitions

  • the aim of the present invention is therefore a relay of the type mentioned at the outset to design and specify a procedure for the connection between the core and the yoke, with which in a simple manner even with low material thicknesses good mechanical and magnetic coupling between Core and yoke is made possible by action external mechanical forces on the yoke neither impaired can still be destroyed.
  • This connection between Kern and yoke should be used with a single relay as well Can also be produced with a double relay without particular difficulty be, even if the connection point from the outside is not accessible to attack larger tools.
  • this goal is at the beginning of a relay mentioned type achieved in that the first yoke leg against in the first coil flange by holding elements Movement in the axial direction and secured against swiveling and that the core is blunt at its first end the side surface of the first yoke leg butts and only connected to it in a materially integral manner via its end face is.
  • the bore is therefore omitted in the first yoke leg to accommodate the core end; much more is this core with its end face on the side surface of the yoke butt-welded or soldered.
  • a larger coupling surface is reached between the front Core and yoke than over the yoke bore that has been common until now, since the ring-shaped coupling surface in the bore with very thin material the yoke becomes very small.
  • the holder of the first yoke leg in the coil flange is preferably that the first yoke leg with parallel side edges in grooves of the first coil flange is inserted in a drawer-like manner perpendicular to the coil axis.
  • the yoke leg is expediently from three sides caught in grooves of the coil flange, so that only a movement in the direction of insertion is possible up to the stop is.
  • connection of core and yoke specified according to the invention is fundamentally also advantageous for individual relays, in particular when using quite thin yoke sheets, for example with a thickness of less than 1 mm.
  • the two bobbins to form by a one-piece double bobbin, wherein a common first flange as the middle flange the two carries the first yoke leg and the two second flanges as End flanges sit on opposite sides of the relay.
  • a common first flange as the middle flange the two carries the first yoke leg and the two second flanges as End flanges sit on opposite sides of the relay.
  • the first two yoke legs of such a double relay with the corresponding core ends for another joining process are not accessible, in this case enables the invention
  • Type of connection only such a relay structure in which both windings previously on a common Coil formers can be applied and the two Cores subsequently from two opposite sides in the double bobbin are used.
  • cores with enlarged pole plates, because the cores from the armature side into the respective coil body be plugged in.
  • All metals can be used with Alloy iron and have a lower melting point than iron have, for example around 1000 ° C or lower.
  • the Layer thickness of the brazing material on the surface of the The core or yoke is usually between 4 and 6 around.
  • the contacting plate mentioned does not weld the two yoke legs as it is a very large one Forms contact surface; after welding or Brazing easily pulled out of the middle flange become.
  • the arrangement of the two switching systems with cores aligned with each other and closely spaced first yoke legs that pass through the type of core-yoke connection possible is also a close magnetic coupling of the two switching systems he follows.
  • This magnetic coupling can also be used of the double relay can be used. If, for example the two excitation coils are wound and excited so that the magnetic fluxes through both cores are in series the excitation of one magnet system also the response the other, so that overall the responsiveness of the Double relay is improved. In certain cases, the mutual influence also by correspondingly opposite Excitation can be exploited.
  • the relay shown in Figures 1 and 2 has one Socket 1, on which two switching systems A and B are mirror-symmetrical to a in Figure 1 by the coordinates x and z defined symmetry plane are arranged. Because in the two Switching systems A and B all parts either mirror symmetrical are arranged or designed mirror-symmetrical and the have the same function, the same reference numerals for both switching systems used.
  • the base 1 is essentially designed as a flat plate, which defines a bottom side 11; on this is vertical a projection 12 is formed on top, the labyrinthine is designed to plug channels 13 for two pairs of fixed contact carriers 14 and 15 and plug-in channels 16 for two spring supports 17 to form.
  • the fixed contact carriers and the spring carriers connect to the bottom of the base with pins 1 off.
  • the fixed contact carrier 14 carries an NC contact 14a, while the fixed contact carrier 15 with a Normally open contact 15a is provided.
  • Each of the two spring supports 17 has a solder tab 17a bent to the side.
  • a double bobbin 2 is arranged on the base. He has one in the plane of symmetry between the two switching systems horizontal center flange 21 and two end flanges 22, each between the center flange and each of the end flanges a winding 23 is arranged. Each of the end flanges 22 has on the spring supports 14 and 15 facing away Page a flange 24 with two coil pins anchored therein 25. Inside each winding is 23 a core 31 with a pole plate from the outside into the coil former 32 inserted so that the pole plate 32 partially in a recess of the end flange 22; to the flange approach 24 the pole plate is cut on one side.
  • each switching system has an angled yoke 33 with a first yoke leg 34 and a second yoke leg 35, both with their planes perpendicular to each other and stand perpendicular to the bottom side 11.
  • the first two yoke legs 34 are parallel to each other in a lateral opening 26 of the middle flange 21 inserted (see also FIG 6).
  • This opening 26 in the central web has a circumferential one Center web 27, whereby one for each of the yoke legs 34 three sides circumferential edge groove 28 is formed, in which the respective yoke leg 34 is inserted like a drawer.
  • the thickness of the web 27 makes the insulation distance ensured between the two yoke legs 34.
  • An approximately plate-shaped anchor 4 stands with its main plane also perpendicular to the bottom side 11; he is in the present Example only in adaptation to the bobbin shape slightly cranked.
  • the anchor 4 is on the free end edge 35a of the second yoke leg 35, without with the yoke over a bearing spring or the like to be connected.
  • the anchor is stored and held rather via a contact spring 41, which has an end portion 41a rests laterally on the anchor and over a or two rivets 42 is connected to the anchor.
  • the contact spring 41 toward the free end of the anchor is split in a fork shape and thus forms a contact leg 43 with a movable center contact 43a and a connecting leg 44.
  • All sections of the cranked and bent contact spring 41 are perpendicular to Bottom side 11, so that the contact leg 43 essentially lies above the connecting leg 44.
  • On the connecting leg 44 is a fastening portion approximately perpendicular 45 bent, the hook-shaped at its free end inwardly curved spring tab 46 carries.
  • the fastening section 45 is between a vertical insulating wall 18 of the Base approach 12 on the one hand and the soldering tab 17a of the spring support 17 inserted and to the approach 12 of the base 1 with the spring tab 46 clamped.
  • the soldering tab 17a each conductively connected to the fastening section 45, preferably soldered or welded.
  • the base 1 is equipped with the contact carriers.
  • the two too Spring carriers 17 for both switching systems are preferred used contiguously in the base 1 and only then the separation point 143 separated from each other.
  • the intended butt welding of the core to the Yoke leg 34 is particularly advantageous if the yoke is made of a thin and space-saving sheet, for example with a thickness of ⁇ 1 mm.
  • the one there effective magnetic saturation values for thin sheets also has a positive effect on the magnetic circuit.
  • the two anchors 4 with the mirror-image bent contact springs 41 are inserted into the base after the coil former, the fastening section 45 of the respective contact spring between the insulating wall 18 and the soldering tab 17a inserted by means of the spring tab 46 on the neck 12 of the Base is clamped.
  • the solder tab is 17a on the side facing the fastening section 45 provided with a tin coating 17b so that it can be coated with a Heat source to the attachment portion 45 of the contact spring 41 can be soldered. This is done, for example using a TIG arc. But one would also be possible Soldering or welding connection using a laser or using a other heat source.
  • the method according to the invention can be used Construction not only as a double relay, but also also run as a single relay.
  • Such a section is shown in FIG. 4.
  • the halved base and the halved bobbin to adjust on the cutting side, so that also with one the half-sized housing cap the closed Individual relay is created.
  • the remaining parts can be left unchanged can also be used for the single relay, so that there is a own description unnecessary.
