Definitions

  • Electromagnetic switching device especially a contactor
  • the invention relates to an electromagnetic switching device, in particular a contactor, with a plug-in unit which can be inserted into a switching device housing and which comprises a coil former for a coil, as is known, for example, from WO 95/12891.
  • Such a plug-in unit also referred to as a coil assembly, consists at least of a coil former which carries one or more copper windings and a connection area via which the winding is supplied with an external voltage.
  • the coil assembly forms the drive for the electromagnetic switching device.
  • a special embodiment of such a drive is, for example, the so-called economy drive.
  • a relatively high switch-on or tightening energy is used
  • Switching of the switching device is required to switch back to a significantly lower holding energy at a predetermined point in time. This has the advantage that the energy consumption of the switching device is reduced in the switched-on state and, accordingly, the power loss and the associated heat radiation is reduced.
  • Such an economy circuit can be implemented purely electronically.
  • the coil is provided with only a single winding, which is connected to an electronic assembly, with the aid of which the economy circuit is implemented in a purely electronic manner by reducing the current flowing through the winding to a value required to hold the armature becomes.
  • an attachment housing for an electromagnetic switching device for example for a contactor, known from EP 0 453 918 B1
  • a molding penetrates the front of the attachment housing, in which a slide which can be coupled to the switch position indicator of the switching device is mounted, so that this slide The position of the switching device can be seen on the front and the switching device can be switched on mechanically.
  • the invention is based on the object of specifying an electromagnetic switching device of the type mentioned at the outset with an electronic assembly which can be manufactured with as little assembly effort as possible and in which operating or contact elements which are guided outward through the housing wall can be easily produced in terms of production technology.
  • An electromagnetic switching device in particular a contactor, comprises a switching device housing and an insertable therein
  • Plug-in unit which contains a bobbin for a coil and an electronic assembly arranged on a housing cover of the plug-in unit.
  • the assembly is arranged on a printed circuit board, which is mounted in a trough-shaped recess of the housing cover, and which is on the
  • Flat side facing the housing cover is equipped with at least one contact or control element which projects into a recess arranged on the front of the housing cover.
  • the contact or control elements are arranged directly on the circuit board also receiving the electronic assembly, the number of assembly steps in the manufacture of the switching device and thus the manufacturing outlay are reduced.
  • the electronic assembly comprises an economy circuit.
  • the circuit board is equipped on both sides, so that there is only a small distance between the circuit board and
  • the recess on the inside is surrounded by a sealing element on which the printed circuit board rests and thus seals the recess against the recess.
  • circuit board is embedded in a potting compound for its mechanical fixation and for protecting the electronic components arranged on it, since in this way the potting compound is prevented from penetrating into the recess in a particularly simple manner and without further production engineering measures.
  • the coil former is provided on one of its end faces with at least one connecting arm with which it is mounted on the housing cover, the other end face in particular having at least one latching hook which latches in a corresponding recess on the housing cover. This ensures a stable mounting of the bobbin on the housing cover.
