Definitions

  • the present invention relates to a bistable contactor having at least one Coil and a relative to the coil movable armature with contacts that together with the contacts for opening or closing a circuit by means of the coil from a first stable position into a second stable position can be transferred, and a permanent magnet in which the armature is in one of its stable positions is supported against the coil, wherein the permanent magnet is stationary relative to the coil and a spring element that moves the armature to the other stable position from the permanent magnet spaced biased.
  • Such a contactor is known, for example, from DE 1 464 867, which is considered to be the closest prior art.
  • This document describes two coils and an armature movable relative to the coils.
  • the armature is for closing a circuit by means of the coils of a first stable position in a second stable position can be transferred.
  • Another contactor is known for example from DE 197 44 396.
  • the contacts are resiliently mounted on the anchor.
  • To open and close a Circuit is the armature by exciting the coil from a first stable position, in which the contacts spaced from corresponding mating contacts of the relay are transferred to a second stable position in which the contacts on the mating contacts applied to close the circuit.
  • the permanent magnet is attached to the anchor and is therefore movable relative to the spool.
  • the coil is energized for a short time. I'm not excited state is caused by the permanent magnet in the two stable positions each closed a magnetic circuit, so that the armature respectively in one of the two stable positions is maintained.
  • the permanent magnet increases the inertia of the anchor. Especially with shaking loads, it can then lead to contact problems come. The switching speed is also limited by this.
  • the object of the invention is therefore, bistable contactors of the type mentioned in such a way to develop further that higher switching speeds can be achieved and at the same time a secure contact is ensured with closed circuit and the Design of the contactor is compact.
  • the object is achieved in that the coils as concentric mutually arranged cylindrical coils are formed.
  • one of the two bistable Positions of the armature on the permanent magnet preferably abut the Pohlschuh. This makes it possible to realize a particularly stable position of the armature, as in Contrary to conventional bistable contactors no air gap between anchor and Permanent magnet in the respective stable position exists.
  • two coils can be provided, wherein by exciting each of a coil, the armature in one of its two stable positions is convertible. This does not require the coil to move the Anchor between the two stable positions each umkupupolen. Instead, you can in each case a coil can be used for transferring in one of the two positions. As a result, the circuit complexity can be reduced.
  • the permanent magnet within the one Coil or coils is arranged. This also makes the contactor more compact shape.
  • the permanent magnets can be arranged by the inside of the coil or one of the coils Permanent magnets generate a strong magnetic flux.
  • the spring element as a compression spring is trained.
  • the anchor can be reliable and in a simple way bias in one of its two stable positions.
  • the single figure shows the bistable contactor according to the invention in a sectional view.
  • the contactor 1 has a substantially cylindrical housing 2 that made an upper housing part 3 and a lower housing part 4 consists.
  • the upper housing part 3 and the lower housing part 4 are placed on one another like a flange and connected by screws 5.
  • a coil holder 6 At the bottom of the housing base 4 is a coil holder 6, on which two concentric coils 7th and 8 are attached.
  • the two coils 7 and 8 are substantially cylindrical formed, with its axis of symmetry in the axis of symmetry of the housing 2 lies. Between the coil holder 6 and the coils 7 and 8 extends Guide element 9 made of plastic.
  • the guide element 9 has a cylindrical, substantially tubular Guide portion 10 and a radially extending flange portion 11.
  • the guide portion 10 extends through the interior of the two Coils in the axial direction.
  • the flange section is located between Coil holder 6 and the coils 7 and 8, wherein it extends substantially radially.
  • the bobbin holder 6 is provided with threads 12, in which the screws 5 are screwed become.
  • the screws 5 extend through through holes 13 and 14 respectively in the upper housing part 3 and lower housing part 4, so that the Screws 5, the upper housing part 3 and the lower housing part 4 with each other and with connect the bobbin holder 6.
  • a flange 15th provided, which is connected via holding elements 16 with the coil holder 6.
  • a permanent magnet with pole piece 17 which has a Screw 18 and a thread, not shown, is connected to the flange 15.
  • the permanent magnet 17 is arranged centrally in the axial direction of the coils substantially.
  • two through holes 19 and 20 are provided, in which a Contact element 21 with contacts 22 is received axially displaceable.
  • an anchor 23 arranged, which has a pin 23 attached to the anchor 24 and a Support member 25 is connected to a holder 26 of the contact element 21.
  • the Holder 26 engages around the support member 25 whose diameter is greater than the diameter of the pin is, thereby the armature 23 and the contact element 21 to connect together in the axial direction.
  • the armature 23 is in a known manner of magnetizable material, such as. Metal produced.
  • the Through opening 20 is arranged in the lower housing part 4 at an intermediate floor, which is provided with a receptacle 27.
  • the receptacle 27 is concentric with the Symmetry axis of the armature and serves to receive a compression spring 28, which is between the receptacle 27 and a pressure surface 29 of the contact element 21 is supported.
  • a compression spring 28 which is between the receptacle 27 and a pressure surface 29 of the contact element 21 is supported.
  • a counter-contact element 30 provided within the housing 2, on the upper housing part 3, a counter-contact element 30 provided.
  • the mating contact element 30 has mating contacts 31, which can be brought into contact with the contacts 22.
  • a compression spring 32 is biasing the mating contact element 30 in the illustration in the figure downwards, ie towards the contact element.
  • the mating contact element is to slightly movable in the axial direction of the armature.
  • the contactor can via the flange 15, z. B. an electric machine mounted become.
  • This assembly takes place in a known manner and therefore need not be further explained become.
  • the arrangement of armature 23, contact element 21 and contact 22nd can in the figure in the figure in the vertical direction between two stable Positions are moved back and forth. In the first, lowered stable position the armature 23 comes against the pole piece of the permanent magnet 17 in abutment. Of the Anchor 23 is held against the pressure force of the compression spring 28. In the second, raised position shown in the figure in the figure the figure the armature 23 is spaced from the permanent magnet 17. The contact element 21 with the armature 23 is biased by the compression spring 28 in the raised position. This stable position is shown in the figure.
  • the contacts 22 and mating contacts 31 disengaged, so that a not shown Circuit can be opened.
  • the contacts 22 and mating contacts 31 In the first, lowered position are the contacts 22 and mating contacts 31 in engagement, so that the circuit is closed.
  • the contactor could also be designed so that in the lowered Position of the circuit interrupted and closed in the raised position is.
  • the transfer of the armature 23 from the first to the second position and vice versa takes place through the two coils 7 and 8.
  • the coil 7 and for transferring the armature of the second in the first position the coil 8 briefly energized.
  • the armature 23 remains in the first or second stable position, depending on which of the two coils 7 and 8 were previously operated.
  • the armature 23 In the first lowered position, the armature 23 is located on the pole piece of the permanent magnet at. This concern is a strong attraction to the anchor 23rd is applied, so that the armature 23 is securely held in the first stable position.
