Definitions

  • the invention relates to a bistable relay, in particular for the high current range, with a coil assembly and a movable armature, which is attracted or repelled by the magnetic flux generated in the coil assembly and thereby opens or closes contacts, wherein in the relay at least one holding means is provided with the anchor can be fixed in position.
  • Such a relay is from the DE 297 24 595 U1 known.
  • Bistable relays are used as switching elements in various fields of defense and aviation, in commercial vehicles, rail vehicles, construction machinery and industrial trucks.
  • bistable relays had to be externally supplied with a precisely defined coil signal for switching on or off. This often led to field failures caused by overcurrent coils.
  • bistable relays have so far had no automatic shutdown in case of power failure.
  • the DE 297 24 595 U1 discloses a bistable relay having at least one coil and a movable armature, in which even after switching off the control current of the at least one coil, the armature can be held in position. To move the armature in an off position of the relay, the known relay must be acted upon by a corresponding control current.
  • the invention is based on the object to provide a bistable relay whose armature is movable without external control signals in an off position of the relay.
  • the object is achieved by an electric storage, with the energy of the armature is movable in an off position of the relay.
  • the drive circuit can drive the relay in such a way that when a voltage is applied to the relay first charged the electrical storage and then the relay is turned on. In case of failure of the supply voltage of the electrical storage can then take over the task of safely turn off the bistable relay.
  • a relay with a safety shutdown can be realized by the electrical storage.
  • the bistable relay can be controlled via a single connection, such as a monostable relay.
  • a control signal for moving the armature in an on position of the relay is sufficient.
  • the relay no longer has to be supplied with a control signal from the outside.
  • the electrical memory provides the necessary current pulse to move the armature to turn off the relay.
  • the electrical storage is preferably integrated in the relay. Due to the integration of the electrical storage, a compact design of the relay is possible.
  • the relay can be used, for example, wherever a conventional monostable relay is to be replaced by a bistable relay without holding currents.
  • Capacitors can be charged and discharged quickly without a memory effect.
  • the coil assembly of the relay may comprise a single coil with two different windings for attracting and repelling the armature.
  • the coil arrangement has an exciter coil and a discharge coil. Excitation and discharge coil can be arranged one above the other or next to each other in the same bobbin.
  • control unit can integrate further safety functions such as polarity reversal protection, short-circuit protection or coil extinction into the relay.
  • control unit can integrate further safety functions such as polarity reversal protection, short-circuit protection or coil extinction into the relay.
  • an undervoltage protection integrated in the control unit can protect the relay against indeterminate operating states.
  • the control unit may preferably be designed such that the relay according to the invention can replace a conventional monostable relay, without having to change anything to the external control of the relay.
  • the relay can be provided for controlling the relay two or three ports.
  • To control the relay for example, either a common ground connection or a common positive terminal and two other connections for switching on or off be provided of the relay.
  • two connections for the power supply and a third connection with an almost powerless control signal for switching on and off of the relay can be provided.
  • the control unit may preferably be formed on a substantially round circuit board on the housing of the coil assembly. Furthermore, the coil contacts can be passed through the board.
  • the described arrangement of the board a compact design of the relay is made possible with a simultaneous simple power supply of all energized relay elements.
  • the individual elements of the relay can be dimensioned such that the relay can be controlled by current pulses of a duration of less than 50 ms.
  • the single figure shows a partially sectioned view of a bistable relay 10 according to the invention, which has a housing 12 and a fastening arrangement 14.
  • a DIN bayonet connector 16 is arranged, through which the relay 10 can be fastened together with the mounting assembly 14 in an application, such as a vehicle.
  • the housing 12 is designed as a metal housing to shield the relay 10 from electrical and magnetic fields of the environment, such as a motor.
  • connection unit 18 In the upper part of the relay 10, a connection unit 18 is arranged.
  • the connection unit 18 has two main contact terminals 20.1 and 20.2.
  • the two main contact terminals 20.1 and 20.2 can be electrically connected or disconnected when switching the relay by moving a main contact bridge 22.
  • the main contact bridge 22 is connected to an armature 24 which is moved when the coil arrangement 26 is energized.
  • the coil assembly 26 has an excitation and a discharge coil.
  • the coil assembly 26 has two permanent magnets (not shown) which hold the armature 24 in the on position or off position after the coil current is turned off.
  • the coil assembly 26 is electrically connected by means of a coil contact 28 with a printed circuit board 30.
  • the printed circuit board 30 is in turn electrically connected to an energy store 32.
  • To control the relay 10 18 three control contacts (not shown) are provided in the connection unit.
  • the energy store 32 which is designed in the form of a capacitor, is first charged. Subsequently, the control signal is modulated on the board 30 to a surge, with which the excitation coil is energized. The armature 24 is thereby moved upwardly in the direction of the arrow 34 and connects the main contact terminals 20.1 and 20.2 through the main contact bridge 22. The armature 24 is held by a permanent magnet of the coil assembly 26 in this position. The relay 10 can thus be held almost without power in the on position. To turn off the relay 10, the voltage is taken from the control contacts of the relay 10. This is registered by the control unit 30.
  • the control unit 30 energizes the discharge coil of the coil assembly 26, the armature 24 is moved counter to the direction of the arrow 34 down to the off position of the relay 10, and the main contact bridge 22 separates the main contact terminals 20.1 and 20.2 from each other. Even with an unwanted drop in the voltage at the control contacts, the relay is thus turned off.
  • the relay 10 thus has an integrated safety shutdown.
  • the wiring of the control unit 30 can preferably be done in three ways.
  • two control contacts are connected to a continuous voltage supply.
  • the relay 10 can be switched on by a high level on a third control contact and off by a low level on the same control contact.
  • the control unit 30 enables almost powerless switching.
  • a first control contact is set to ground.
  • the relay 10 is then turned on by applying a positive voltage to a second control contact and turned off again by a positive voltage at a third control contact.
  • the relay 10 can be connected in a third variant such that a positive voltage is applied to a first control contact and the two other control contacts for switching on and off are subjected to a negative voltage.
  • the wiring options described above are to be regarded as exemplary only.
  • the relay 10 according to the invention can also be controlled, for example, by only two control contacts, the voltages of which are conducted to the control unit 30.
  • the control unit 30 is short-circuit proof and includes a protected coil drive, a polarity reversal protection and a coil cancellation, so that a faulty or improper control is excluded.
  • the coil assembly 26 is made so compact that the geometries and dimensions of the invention Relays 10 are identical to conventional relays.
  • the relay 10 according to the invention can thus replace any corresponding conventional monostable or bistable relay. Compared with conventional relays, the electronic safety of the relay 10 according to the invention is thereby significantly expanded. Due to the integrated energy storage, a safety shutdown can be realized.
