Definitions

  • the invention relates to an improvement in the execution of the Coil body of a core choke, preferably a toroidal core choke.
  • Toroidal chokes are components with at least two around the ring-like insulated core wound wires (wire windings). Such components can e.g. B. to avoid electrical interference in industrial plants, vehicle control units, Consumer electronics or in household appliances be used.
  • the electrical isolation between the wire windings is usually realized with cardboard inserts.
  • the isolation can also be through a two wire feedthroughs separating middle wall can be reached.
  • a core sheathing is included a built-in mounting base known during assembly on a circuit board in a designated recess or opening is inserted, causing the core choke is fixed on the circuit board.
  • the potting also serves for improvement the thermal conductivity of the component and protects the toroid from moisture.
  • a potting can be made, for example, from adhesive, Epoxy resin or polyurethane exist. Pouring the However, throttling adds extra work Manufacture of the components and is correspondingly high Associated costs.
  • the wire windings to attach the choke core is a loose wire arrangement around the core cladding.
  • the loose wire arrangement around the core is disadvantageous because the mechanical instability of the Construction for the instability of the grid dimension between the electrical Connections and thus lead to short circuits.
  • the object of the present invention is a core choke, which has a choke core in the form of a closed yoke (preferably toroidal choke), so that improve with radial arrangement of the wire connections, the risk of Short circuits are reduced and the manufacturing process is simplified becomes.
  • a choke core in the form of a closed yoke (preferably toroidal choke)
  • the invention provides a bobbin, which for receiving a magnetic choke core.
  • the coil former according to the invention provides an insulating one Core cladding, the choke core to be encased as a closed yoke is formed.
  • the inventive wire guide integrated in the bobbin saves an additional effort for the attachment of the Wire windings on the bobbin and ensures a special high reliability with regard to the core choke Short circuits by ensuring the grid dimension.
  • wire guide devices mentioned can for example as highlights on the underside of the bobbin or the trough.
  • Said choke core is preferably annular. However, it can be any other closed Have a shape, for example one bent into a triangle closed yokes. It can also be O, D or be rectangular in cross section.
  • the bobbin can be made of solid heat-resistant insulating Plastic, for example made of LCP. It is possible, the bobbin as a sealable trough with a cover plate made of the same material.
  • the cover plate can either be snapped on or on lie on the trough.
  • the named coil body is completed with a choke core or - for setting predefined magnetic properties of the component - partially filled out.
  • the choke core consists of a for storing magnetic energy suitable material with magnetic properties, e.g. B. from Ferrites, iron powder or amorphous iron.
  • the bobbin can be with one or with two, facing each other Wire windings arranged through the coil former (through the wire bushings are wrapped through). Under one Wire winding is understood to be a winding around the choke core Wire including all windings between two connections at both ends of the wire.
  • This wire can e.g. B. enamelled copper wire, aluminum wire, wire or metal wire his. The insulation of the windings is done by applying a layer of lacquer or by means of an insulating plastic hose reached.
  • the electrical isolation between several wire windings at an advantageous embodiment of an inventive Core choke is made by a corresponding number of in the middle of the bobbin formed dividers.
  • the design of the dividers depends on the number of wire windings or wire feedthroughs. For example at Such a separator connects two wire feedthroughs opposite sides of the yoke. With more than two wire windings For example, it can be star-shaped his.
  • the position fixation of the core choke according to the invention in the housing or on the board of one device in another advantageous embodiment is such.
  • Said coil former can also have defined gripping surfaces for a gripper arm for automatic loading. This has the advantage that the corresponding manual work is avoided in the manufacture of the terminals.
  • the coil body enveloping the choke core thus takes over in advantageous embodiments several functions simultaneously. It serves to isolate the choke core Electrical isolation between the wire windings, for guidance of the wire and ensuring the grid size and for fixing the position the throttle in application devices. By using it The manufacturing process of the bobbin according to the invention a core choke easier and cheaper than before.
  • the wire windings DW1 and DW2 are around the ring-like bobbin SK wrapped through the wire bushings DD and separated from each other by means of a separator TS.
  • the fixed arrangement the wire windings in the component and compliance with the Pitch between the electrical ones listed above Connections of the two wire windings DW1, DW2 is by arranged on the face between individual windings Wire guides DF guaranteed.
  • a gripping surface for automatic Equipment is marked as GF1.
  • a bracket HA1 is used to fix the component in application devices intended.
  • a coil former SK according to the invention is shown in perspective in FIG Shown from below.
  • FIG 3 shows an advantageous embodiment of an inventive Coil body SK in a perspective view of above.
  • the coil body consists of a trough TR with a Cover plate DP. It is possible that the cover plate is snapped or is resting on the trough.
  • the gripping surface GF2 is here due to the planar geometry of the cover plate DP guaranteed.
  • a bracket device formed on the cover plate HA2 is used to fix the component in position.
  • FIG. 3 Another section in FIG. 3 is already shown in FIG shown coil former of a core choke shown.
  • the cover plate DP is in this embodiment snapped. Another option is that the cover plate rests on the trough.
  • the trough TR and the cover plate DP enclose the choke core KE.
