Definitions

  • the invention relates to an electrical separator.
  • the invention is based, if possible inexpensive manufacture, reliable operation and little Space-consuming construction of the separator support.
  • the invention proposes instead of in High voltage range commonly used ceramic Insulation to use a plastic component which the electrodes itself and the contact surface which connects the electrodes to an electrical lead are, which within this plastic component electrical connection lines between the contact surface and the electrodes are arranged.
  • plastic as an insulator makes it an excellent Vibration resistance ensured. It can also the plastic component with its vibration-damping properties the life of the possibly vibration sensitive Extend electrodes.
  • the plastic component can be injection molded, the rest Components are encapsulated using this plastic can. So, on the one hand, there is a rational production of the whole Assembly allows, in particular a complex Assembly of electrodes, contact surface and the in between existing electrical connection lines are eliminated can, and on the other hand is a particularly space-saving design of the assembly possible, since the encapsulation of the above Components allows a more space-saving arrangement as if set to mount on the electrode holder would.
  • Electrodes can also be particularly advantageous be designed as a one-piece component, for example in injection molding or die casting.
  • the electrodes are interconnected and form a one-piece component, which also forms the contact surface to which the electrical supply line can be connected.
  • the electrodes are made of Plastic. If these electrodes in the input mentioned plastic component are embedded, results from Similar material properties (e.g. coefficient of thermal expansion) optimal low-stress behavior of the Overall created assembly, so that its reliability and susceptibility to interference is further improved.
  • a design of the electrodes made of plastic is surprisingly possible because the functionality of the Electro-separator on the electrical conductivity of the electrodes based and even conductive plastics generally regarded as unfavorable, comparatively high Have resistance to metallic materials. In view of the low currents, this plays comparatively higher resistance of plastic electrodes but not functionally relevant Role, so that good separation performance also such a configuration of the electrodes made of plastic ensured can be.
  • the electrodes, their connecting lines and the contact surface is designed as a one-piece workpiece are a particularly inexpensive manufacture of this Workpiece possible in plastic injection molding, so that the electrical separator both in terms of its manufacturing costs as well as in terms of its operating behavior is inexpensive.
  • Electrode holder 1 denotes an electrode holder in general.
  • the Electrode holder 1 is made of plastic, it has four holes 2, with the help of which the electrode holder is attached can be, for example in an oil mist-containing component, so that the electrode holder 1 shown for the deposition of Oil, for example in crankcase ventilation in internal combustion engines can be used so that the separated oil particles are returned to the engine in an environmentally friendly manner can be.
  • three electrodes 3 are provided, which as Two-stage spray electrodes are designed: These spray electrodes each have a corona area 4, which with a is designed needle-like small diameter and a electrostatically effective area 5, on the other hand, considerably larger diameter.
  • the electrostatic effective areas 5 of the electrodes 3 are hollow. These areas of the electrodes 3 consist of an electrical conductive plastic, in the tips of these areas 5 metallic needles are used, the corona areas 4th form the electrodes 3.
  • a total of three electrodes 3 are provided, these are connected to each other by a curved ring line 6, and furthermore the electrodes 3 and the ring line 6 in one piece are formed by an injection molded part.
  • the Ring line 6 Opposite the Ring line 6 is this component made of electrically conductive Plastic extended radially outwards. In this outer area the component forms a contact surface 7, which is used for contacting an electrical supply line.
  • the electrode holder 1 is also made of plastic, however Made of an electrically insulating plastic, with which the electrode assembly is encapsulated. Overall, the illustrated Assembly are therefore handled in one piece and enables quick assembly of an electrical separator.
  • the electrode holder 1 In the field of Contact surface 7, the electrode holder 1 has a recess 8 on, which is designed in two stages and the electrical supply including their insulation can take, with the Attaching this electrical insulation to the electrode holder 1 is not discussed in more detail here. Possibly can on the surrounding the recess 8, from the electrode holder 1 sleeve formed a locking surface to be provided the electrical insulation by means of a snap or snap connection to attach to the electrode holder 1 and the electrical Ensure contacting of the contact surface 7.
  • the material of the electrode holder 1 be configured in two components to both the intended To have insulation properties as well as the desired Dimensional stability.
  • the material of the electrode holder 1 may not be provided a single material around the electrically conductive components spray around, but the electrically conductive components adjacent to use a first material for the electrode holder 1 and surrounding this material a second material, which forms the outer contour of the electrode holder 1.
  • the injection molded, electrically conductive components 6 and 7 are not made of a conductive Plastic, but from metal.
  • the electrode holder made of plastic can also have other functions, such as Admission of seals, for admission of fasteners and the same.
