Definitions

  • the present invention relates to a combustion engine ignition member and more particularly such a member comprising at least one bent outlet chimney arranged to receive a cable end with lateral engagement.
  • This electrical circuit consists of a high voltage cable, one end of which is mounted on the spark plug and the other end of the high voltage chimney of the ignition member.
  • a disconnection of the cable from the high-voltage chimney can occur either due to a faulty installation, for example during a maintenance operation, or due to the tremors or vibrations normally occurring when the engine is used on which is mounted the ignition member.
  • the present invention aims to overcome these drawbacks.
  • the subject of the invention is an ignition member of an internal combustion engine, comprising at least one bent outlet chimney arranged to receive a cable end connector with lateral engagement, characterized in that it includes a stop offset from the axis of the end of the chimney to allow the end of the cable to be engaged in a first angular position, for positioning, of the latter relative to the chimney, and to prevent its disconnection in a second angular position, of use.
  • the means of the invention therefore in no way complicate the mounting of the cable connector on the outlet chimney since this mounting is carried out by a simple engagement, the locking being effected simply by rotation of the end of the cable.
  • holding means are provided to maintain, in use, the end of the cable in its second angular position.
  • These holding means may for example comprise a cover mounted on the body of the ignition member.
  • the device of Figure 1 comprises a housing 1 receiving three ignition coils 2 embedded in a resin.
  • the low voltage windings of the coils 2 are supplied by a connector 3.
  • These coils are double output coils, the internal combustion engine for which the device is intended being a six-cylinder V engine.
  • the device of Figure 1 is directly mounted above three of the engine cylinders so that the first outputs 4 of each coil are directly connected to the spark plugs.
  • the other outlets 5 here consist of bent chimneys. These outlet chimneys 5 are intended to be each connected to the spark plug of one of the other three cylinders of the engine by a connecting cable.
  • each stop 6 is located in front of the end of the corresponding chimney and offset relative to its axis.
  • Each stop 6 also has, on its side facing the chimney 5, an arcuate shape.
  • FIG. 2a represents the connector 8 before it engages on the end of the chimney 5. Its angular position is such that the end 7 of the cable is directed upwards.
  • the connector 8 has undergone a rotation of 90 ° such that the end of the cable 7 is now horizontal, engaged in the corresponding arc form of the stopper 6. In this position, the connector 8 cannot no longer be cleared from the outlet chimney 5.
  • a cover 9 is mounted on the body of the device and prevents the connector 8 from returning to its engagement and disconnection position.
  • the cover 9 is not necessary.
  • the length of the cable 7 can be provided such that, when its other end is mounted on the corresponding spark plug, it can no longer pivot.
