Definitions

  • the invention relates to a potted encapsulated device, especially a potted, explosion-proof electromagnet with a preferably in a housing in a Potting compound embedded coil and with an iron circle, the one also embedded in the sealing compound, contact elements arranged inside the housing with external ones Lines are connectable.
  • Encapsulated devices have long been known and go for example from DE-G 90 03 343.4 and CH-A-627 584 discloses a potted encapsulated device describes according to the preamble of claim 1.
  • the sealing compound As for encapsulated, explosion-proof electromagnets it is required that the sealing compound the electrical insulation guaranteed so that no explosive gas mixture can lead to ignition sources, and that the sealing compound also withstands mechanical loads and chemical influences away from the equipment, it is necessary also the contact elements for connecting external lines in to embed the sealing compound. Furthermore must be provided be that the contact elements inside the housing in a cavity separated from the environment is arranged, so that this also ensures that no explosive Gas mixture can get to the contact elements.
  • the object of the invention is therefore a potted To further develop a device of the generic type that with simple manufacture and simple construction easy approach and contact of the external lines to the contact elements is possible.
  • the contact elements protrude beyond the housing sealing compound on the face and the arrangement of a connected to the cavity and by the contact elements and the cover element leading cable duct in the Potting compound have the particularly great advantage that with a compact construction of the device, easy to bring up of the external lines to the contact elements and a optimal use of tools such as screwdrivers or the like is possible.
  • the cavity in which the contact elements must be arranged to be non-explosive a the front of the housing in the area of the contact elements final, preferably curved cover element is formed will that after contacting the contact elements the housing is attachable.
  • the protruding contact elements in connection with this cover element allow a easy installation of external lines and an explosion-proof Arrangement of the contact elements in the by the Lid element formed cavity.
  • the lid element in addition to a domed, also a cup-shaped or other shape forming a cavity can. Another advantage is that due to the level Contact surface of the lid uses a flat sealing element can be.
  • the contact elements there are also circuits in many cases or electrical components together with the contact elements, the coil and the iron circle in the potting compound have to be embedded, for example fuses, and there is an encapsulation of these electrical components with a thermoplastic compound under high pressure and therefore not damage to the components can be excluded is at a very advantageous Embodiment provided that the contact elements and further electrical components in a cup-shaped, in which Housing attachable component arranged and with a thermosetting Molding compound are cast. In this way especially the very sensitive fuses not damaged.
  • thermosetting molding compound The coil, the iron circle and this cup-shaped, with the thermosetting molding compound is cast with a component encapsulated thermoplastic molding compound.
  • An encapsulated device in the form of an electromagnet shown in Fig. 1 to 3, comprises a plastic or metal existing housing 10 in which an in Fig. 3 shown iron circle 60 and a coil 70 arranged which are connected via contact elements 20 to (not shown) electrical lines are connectable.
  • the contact elements are 20 in a potting compound arranged in the housing 10 12 embedded and stand on the front over that Housing 10 flush sealing compound 12 over. On this way can be brought up to the contact elements 20 external lines easily with the contact elements 20 connected in an electrically conductive manner by screw-clamp connections 22 become.
  • a cable channel 11 is provided in the potting compound 12, essentially of the contact elements 20 runs away to the upper case front.
  • Cable duct 11 becomes a very compact construction of the electromagnet reached because the cable is essentially parallel to Direction of action of the electromagnet led away upwards can be.
  • a housing cover 40 can be attached, the explosion-proof Forms cavity in which the contact elements 20 are arranged.
  • the coil 70, the iron circle 60, the contact elements 20 and if necessary, further components are in a sealing compound embedded.
  • a thermoplastic is preferred Molding compound for the encapsulation of the iron circle 60 and the coil 70 used under high pressure.
  • the contact elements 20 and these components first in a pot-shaped, arranged in the housing 10 attachable component 30 and cast with a thermosetting molding compound 31. To this This ensures that these components by the Embedding in the molding compound should not be destroyed.
  • the cup-shaped component 30 is then connected to the iron circle 60 and the coil 70 (see FIG. 3) and only then with molded around the thermoplastic molding compound.
