Definitions

  • the invention relates to an electromagnetic switching device, in particular a contactor, comprising a housing lower part and a housing upper part, wherein in the housing upper part a connection area for connecting at least one conductor and at least one coil terminal is provided, and wherein in the lower housing part, a drive unit is arranged, consisting of a yoke, a Anchor and a coil with a bobbin, and switching devices with piezo drive.
  • the coil connection in the case of electromagnetic switching devices, in the case of the connection between the coil connection and the drive unit, the coil connection is basically designed as a rigid unit, that is to say as a connection made of conductors and arranged on the outside of the housing. This is electrically connected to the arranged inside the housing drive.
  • the drive is designed as a dynamic unit that moves when switching on and off. The electrical connection must compensate for the movements that occur during switching on and off.
  • connection device for connecting an end region of an excitation coil applied to a coil body to an outer conductor.
  • the connecting device on the bobbin a first and a second mounting dome are assigned, each having a recess with a partially electrically conductive connection plate.
  • the terminal plate has two bent portions, a hole for screwing a terminal screw or a protruding tongue, which carries a spring-type terminal for connecting an outer conductor, so that the respective customer request can be met.
  • connection module for driving the magnetic drive known.
  • the connection module is due to the spatial arrangement facilitating the connection of the control line with connected main conductors and the electrical contacting of the magnetic coil with the control line.
  • the contacting takes place by means of strip-like connecting conductors, which are provided with a control terminal for connecting the control line and can be designed as a screw or spring terminal.
  • the strip-like connection conductors protrude from the housing of the connection module and contact by inserting into the main housing by means of plug connection, the magnetic coil with the dedicated control terminals on the bobbin in the housing base.
  • the invention has for its object to provide a switching device, in particular an electromagnetic switching device, wherein the contact with the drive unit is designed so that the dynamics of the drive unit is compensated.
  • the electromagnetic switching device in particular a contactor, has a lower housing part and an upper housing part, wherein in the housing upper part a connection area for connecting at least one conductor and at least one coil terminal is provided and wherein in the lower housing part a drive unit is arranged, consisting of a yoke, an armature and a coil with a bobbin.
  • the invention is characterized in that the coil connection contacts the drive unit by means of a compensation element path compensating.
  • connection region On the upper housing part of the electromagnetic switching device, a connection region is provided, which is designed for connecting at least one external main conductor and a coil connection on the same plane.
  • the coil terminal has a terminal area with different terminal types, such as a screw terminal or a spring-type terminal, and a second area, which is guided into the housing interior and carries a compensation element.
  • the compensating element can be frictionally clamped between two units, the coil connection and the drive unit or positively clamped between the two units in each case in one unit and in the other unit in order to compensate compensating for the movements arising during the switching process.
  • a particularly advantageous embodiment consists in that a compensation element can be fastened to the coil connection, so that the surface at the connection point is not damaged by micro-movements.
  • the compensation element is electrically conductive, as a result, a secure contact is given.
  • the compensation element is frictionally arranged between two units, whereby a secure connection of the two units is given.
  • a particularly advantageous embodiment is that the compensation element is once arranged positively and once positively between two units, since the surfaces to be contacted are geometrically very simple and are so very insensitive to tolerances.
  • the compensation element is designed as a spring, since in this way no switching movements are transmitted from the drive unit to the coil terminal.
  • the compensating element is designed as a leaf spring, so that no switching movements are transmitted from the drive unit to the coil terminal.
  • a particularly advantageous embodiment is that the coil terminal is designed as a contact, so that an external conductor can be connected.
  • a further advantageous embodiment consists in that the coil connection has two regions, wherein the first region is designed as a connection region and the second region for fastening a compensation element.
  • the second region of the coil terminal is guided into the housing interior, whereby a path compensating element can be fastened.
  • the second region of the coil terminal is formed as a pin, so that a path compensating element can be plugged in a form-fitting manner.
  • a particularly advantageous embodiment is that the bobbin has devices for receiving the compensating element for contacting the coil, as a result, an accurate positioning of the modules to each other during assembly is not necessary.
  • the drive unit is formed connection neutral, wherein regardless of the selected connection type of the coil terminal, such as screw or spring terminal, a drive unit for different device variants can be used.
  • the switching device has an upper housing part and a lower housing part, wherein in the upper housing part a connection area for connecting at least one conductor and at least one connection for connecting a drive unit is provided, and wherein a drive unit is arranged in the lower housing part, which is designed as a piezo drive is.
  • This switching device is characterized in that the piezo drive is contacted by means of a compensating path way balancing.
  • the contacting with compensating element according to the invention is accordingly also suitable for piezo drives.
  • Fig. 1 an electromagnetic switching device 1 is shown with an upper housing part 2, on which a connection region 3 is arranged.
  • a coil connection 4 is arranged in a plane with conductor connections 5, wherein the coil connection 4 is designed as a screw connection 6.
  • the drive unit 7 is arranged, which consists of a yoke 8, an armature 9 and a bobbin 10.
  • devices 11 are molded for receiving a compensation element 12 and contact lugs 13 are arranged.
  • the compensating element 12 is frictionally held between the inwardly projecting region of the coil terminal 4 and the bobbin 10 provided with the devices 11.
  • Fig. 2 shows the electromagnetic switching device 1 in a further embodiment in which the coil terminal 4 is formed as a spring-loaded terminal 14.
  • the compensating element 12 is positively held with the inwardly projecting region of the coil terminal 4 and with the coil 11 provided with the device 10 frictionally.
