Definitions

  • the present invention relates to a removable fixing device for an ignition coil for an internal combustion engine, used in particular in static ignition devices of the coil-by-spark type.
  • the present invention also relates to an ignition coil using this device.
  • an ignition device for an internal combustion engine consists of a distributor igniter itself comprising the breaker, the condenser, the centrifugal advance system supplemented by one or more vacuum correction devices and finally the distribution finger.
  • the igniter head also called distribution head, a high voltage coil and spark plugs, one per cylinder in general.
  • the present invention therefore aims to a removable fixing device of a coil for static ignition device on a cylinder head cover which allows quickly and easily mounting and dismounting of the coil so as to easily access the spark plug and which either very inexpensive.
  • the removable fixing device on a cylinder head cover of an internal combustion engine of an ignition coil used in particular for the implementation of a static ignition device of the coil-by-spark type , is characterized in that it comprises at least one elastic, mentally deformable clip which is fixed by one end to the ignition coil and the other end of which cooperates elastically with the cylinder head cover.
  • the fixing device comprises two clips arranged on either side of the coil, these clips obtained by molding forming an integral part of the housing or casing of the ignition coil.
  • said clip has substantially the shape of a U, one of the branches of which is fixed to the ignition coil and the other branch of which has a recess which cooperates elastically with a shoulder carried by the cylinder head cover.
  • the invention also relates to an ignition coil for an internal combustion engine, used in particular for the implementation of a static ignition device of the coil-by-spark plug type, characterized in claim 4.
  • an ignition coil 3 housed in part in a recess 8 of the cylinder head cover 6 of the combustion engine of which only the constituent parts of the invention have been shown.
  • the coil 3 is connected to a spark plug 4 by means of a cylindrical socket 2 ensuring the electrical connection.
  • the coil 3 is thus placed vertically on the spark plug well 7 formed in the cylinder head 1 of the engine.
  • the coil 3 is externally in the form of a housing 10 of substantially parallelepiped shape having a peripheral collar 13 also parallelepiped.
  • This plastic housing 10 obtained by molding has two extensions 5 forming two elastically deformable staples projecting on two opposite sides of the housing 10.
  • These staples 15 provide removable attachment of the coil 3 to the cylinder head cover 6, in accordance with the invention.
  • the staples 5 have a shape substantially a U.
  • One of the branches of the U, forming each staple, is attached to the housing 10 at the level of the collar 13 while the other branch has a recess 12 which is capable of being elastically supported under a shoulder 9 of the cylinder head cover 6 projecting into the recess 8 and has a free end curved towards the housing 10.
  • the shape of the recess 8 is perfectly complementary to the housing 10 of the coil 3 which prevents any displacement of the latter in the horizontal plane while the bottom of the recess 8 and the shoulders 9 prevent any vertical displacement.
  • the release of the coil is very simple, just press the free ends of the two clips 5 towards the housing 10 to release the recesses 12 of the shoulders 9 and then extract the coil vertically.
  • the blocking is even simpler since it suffices to push the reel into its housing so that the clips 5 move into position alone and ensure the locking of the reel 3 on the cylinder head cover 6, the recesses 12 bearing under the shoulders 9.
  • the two extensions 5 forming two elastically deformable staples can be manufactured separately from the housing 9 and assembled to this housing by screwing, gluing or any other fixing means.
