Definitions

  • the invention relates to an ignition cable list for the ignition system of an internal combustion engine according to the preamble of claim 1.
  • Such ignition cable list is known from DE-GM 88 11 770.
  • the ignition lines In ignition systems for internal combustion engines, in particular in high-voltage ignition systems for gasoline engines, the ignition lines have so far been laid when mounting the ignition system so that each high-voltage distributor connection is connected to the associated spark plug via an ignition distributor connector, an ignition line and a spark plug connector.
  • the cable routing is either relatively loose only with the help of cable holders as support points or fixing points or with the help of ignition cable shafts through which the ignition cables are pulled.
  • the ignition cable list of the type mentioned in the preamble of claim 1 is also arranged in an oblique installation position, which leads to pressure on the spark plug neck.
  • the object on which the invention is based is therefore to design the ignition cable strip according to the preamble of patent claim 1 in such a way that it can be installed quickly and safely, in particular in a robot-compatible manner.
  • the complicated laying of the ignition cables when assembling the ignition system at the motor vehicle manufacturer is unnecessary, which should be robot-compatible, easier handling in the workshop during repair work is achieved, and there is a mix-up of the ignition sequence and chafing the ignition cables avoided.
  • the optics in the engine compartment are improved and the risk of being bitten is almost eliminated.
  • the exemplary embodiments of the ignition cable strip according to the invention shown in FIGS. 1 to 5 comprise a strip-shaped cover part 1, for example in the form of a plastic injection molded part, on the inside of which ignition cables 11 are laid, which connect the respective spark plug plugs 9 with the plugs of a distributor plug box 2 or an ignition coil plug box in ignition systems without Connect distributor.
  • An end cover 8 is preferably provided at the end of the cover part 1 on the connector box side, which is integrally formed on the cover part 1.
  • a cover part 5 can be formed, which serves to adapt to the outer contour of the cylinder head and can also be molded in one piece onto the cover part 1.
  • sealing lips 10 are further provided, each of which forms centering, supporting and sealing elements.
  • the ignition lines 11, which are preferably high-voltage ignition lines, are led out of the cover part and into the distributor connector box 2 for connection to the distributor connectors, with a further connection for the ignition coil connector 4 being provided on the distributor connector box 2 .
  • the distributor connector box 2 and the cover part 1 are connected to one another in one piece or made from one piece. This training has advantages with regard to the risk of marten bites etc.
  • a plurality of ignition coil plugs are integrated in an ignition coil plug box 12.
  • the cover part 1 is firmly connected to the ignition coil connector box via a connecting part 17 which rigidly connects the cover part 1 and the ignition coil connector box to one another and can be formed in one piece with these components.
  • the spark plug connectors 9 are designed as so-called angled connectors which lie in the axial extension of the spark plug 15 Have plug part and a cable connection part protruding from it at an angle.
  • the cable connection part is provided with a protruding insertion part 19, which can consist of a molded-on protruding ring with which the cable connection part sits in a receiving shoe 20, which is formed in one piece with the cover part 1 on the inside thereof.
  • the receiving shoe 20, which is U-shaped, has an inner, also U-shaped in cross-section, into which the protruding insertion part 19 fits, these components being complementary to one another in terms of their shape and thus forming an at least form-fitting connection with one another.
  • a locking clip 3 formed therewith in one piece, which is resiliently elastic and, in the assembled state of the spark plug connector 9, engages around the plug part lying in the axial extension of the spark plug 15 and thus holds it in place.
  • a contact spring 14 with a conical spring end is arranged in the spark plug connectors 9, which between the spark plug connector end of the spark plug connector 9 and a spring seat 21 of the cable-side part of the spark plug connector 9 in the axial extension of the Spark plug lying part of the spark plug connector 9 is arranged.
  • An interference suppression resistor 13, which is shown in FIG. 7, can be provided on the ignition cable side of the contact spring 14.
  • a design with an intermediate pin 18 without interference suppression is shown in FIG. 8.
  • a cylinder head 16 of an internal combustion engine is shown schematically, on which the ignition cable list with its spark plug connectors is placed is.
  • the cover part 1 with the spark plug connectors 9 is made in one piece, which can be done by inserting and overmolding the connecting wires with the interference suppressors and the spark plug and distributor-side connecting parts in an injection mold.
  • the above-described exemplary embodiments of the ignition cable list according to the invention are thus designed so that all spark plug connectors 9 can be plugged onto the spark plugs in a single plug-in movement, and likewise the distributor plug in the distributor plug box 2 or the ignition coil plug in the ignition coil plug box 12 can be fitted with a single plug-on movement.
  • This enables simplified, robot-friendly assembly at the motor vehicle manufacturer, easier handling in the workshop and prevents mix-up of the ignition sequence and wear through of the ignition cables.
