Definitions

  • the invention relates to an electrical connection arrangement for producing an ignition coil, in particular a pencil ignition coil with an ignition coil rod with a high-voltage outlet and a low-voltage outlet.
  • Ignition coils generate high voltage sparks. This jumps at the arranged on the ignition coil spark plug at the electrodes and thus ignites, for example, the air-fuel mixture of an internal combustion engine. As a rule, this spark plug is supplied with an ignition coil with high voltage.
  • a primary winding and a corresponding secondary winding is provided within the ignition coil. The primary winding is coupled at one end to an ignition starter switch, with its other end connected to a so-called breaker.
  • the secondary winding ie the winding which is responsible for the formation of the ignition spark is connected inside the ignition coil to one end of the primary winding, so that it is grounded.
  • the other end of the secondary winding is connected to the high voltage output, which in turn is connected either to an ignition cable leading to the spark plug, or to which the spark plug is directly located.
  • the secondary winding itself consists of a thin wire, which is coated with a corresponding lacquer layer in order to avoid the contacting of the individual wires during the winding of a specific carrier body or bobbin. After the secondary windings are wound on a carrier, the ends of the respective wires are contacted.
  • thermal contacting methods are generally known, for example soldering or welding.
  • DE3533054 discloses an electrical connection arrangement of a coil having a low-voltage output, wherein a bobbin is provided, on which a wire is wound, which forms a secondary winding, wherein a contact spring is provided on the side of the low-voltage outlet, and which is pushed over a contacting region and contacts the wire of the winding in an end position, wherein the contact spring is pushed over a arranged on the bobbin nose-like element until this element penetrates an opening formed in the contact spring, so that the element and the contact spring lock together.
  • the object of the invention is to produce a connection arrangement with the features of claim 1 between an ignition coil rod of an ignition coil and a secondary or primary winding, which is inexpensive and easy to implement.
  • the basic principle of the solution of the problem is to replace the known from the prior art thermal bonding method. This is achieved in that additional contacting elements have been created, which break during assembly coated with lacquer wire of the secondary winding and thus bring about a corresponding contact.
  • the "cold" contacting method proposed here has the advantage over the previous method that no additional system costs are necessary. Furthermore, additional assembly steps are reduced and also a reduction of exclusion parts can be recorded by the embodiment according to the invention.
  • Another essential advantage of the invention is that no space must be optimized for carrying out the contacting. This means that there is no free space in the area of contacting e.g. must be kept for welding tongs, soldering iron or the like.
  • the nose-like element Upon reaching a defined position, which is provided by an opening or recess on the side of the contact spring, the nose-like element snaps into this opening, so that the contact spring rests on the secondary winding.
  • Fig. 1 is a perspective view of an ignition coil 1 is shown.
  • the ignition coil 1 comprises an ignition coil housing 2 and an ignition coil rod 3 arranged in the ignition coil housing 2. Further, the ignition coil 1 has a high voltage output H side and a low voltage output N side.
  • the low voltage output N side is designed to make contact with a power supply not shown in the drawing, with the high voltage output H side being provided for connection to an ignition wire or spark plug not shown in the drawing.
  • Fig. 2 is the in Fig. 1 shown ignition coil 1 shown in a sectional view; the areas shown are those which relate to the invention essential features of the invention, which are shown in more detail in the following figures.
  • Fig. 3 the ignition coil rod 3 is shown with one side for the high-voltage outlet H and one side for the low-voltage outlet N, the immediately after its assembly as a unit in the in Fig. 1 and 2 illustrated ignition coil housing 2 is inserted.
  • FIG. 4 an enlarged view of the side of the low voltage output M of an ignition coil 1 is shown. It is provided to wind a wire on a bobbin 4, so that the secondary winding 5 provided here results.
  • the one end of the wire of the secondary winding 5 is attached to a so-called Anbindepfosten 6, from which the wire winds on the peripheral surface of the bobbin 4 and extends over a defined support area.
  • This support area also serves as Maisier Scheme 7 for a in Fig. 5 to 9 illustrated contact spring 8 for producing an electrical contact between the secondary winding 5 and the contact spring 8 itself.
  • the support surface 7 is completely covered with the secondary winding 5.
  • the contact spring 8 in the direction of arrow 9 according to Fig. 8 pushed over guide means 10.
  • the contact spring 8 slides along a surface 11 of the ignition coil rod 3 until it is a nose-like Element 12 reached.
  • the contact spring 8 slides on, so that they at a distance from the in Fig. 8 shown bobbin 4 or at a distance to the secondary winding 5 is guided. If the contact spring 8 reaches a defined position, then the nose-like element 12 penetrates into the FIGS. 9 and 10 illustrated opening 13 of the contact spring 8, so that the bottom 14 of the contact spring 8 is fully applied to the secondary winding 5.
