Description

The invention starts from a plug-in connector for

  internal combustion engine ignition shield, connector in which a plug-in receiver of insulating material has an outer part with a recess and a tip immobilized in the splitter box-preferably three electrical conductors inside the splitter box each comprise a plug-in tab; each display tab

  is plugged into the plug receiver and enters the recess.

  the external part to liaise with a counter-

plug.

  For immobilization of the receiver tip

  of the plug in the splitter box, a splitter of

  Existing mage has in the wall of its casing a slot starting at the edge of the casing and whose length is greater than twice its width. This relatively long slot results in practice, due to the existing stresses in the material, to inadmissible deformations of the casing. With the plug connector according to the invention,

  this disadvantage existing in the state of the art is avoided.

  The basic idea of the invention is not to split the

  of the box closed on itself and to dispose the end of the receiver of plug in the least critical middle part

of the wall of the box.

  For this purpose, the invention relates to a connector characterized in that there is provided in the wall of the splitter box, a hole in which the end of the plug receiver can be introduced from the outside, an element is likely to be attached to the part of the tip penetrating into the interior of the casing to allow the plug receiver to be blocked,

  Other features of the invention allow

  try to consider variants of the connector defined above,

  By providing that a groove is provided in each

  one of the lateral faces of the nozzle, and the sheet metal member has two sliders which are slidable in the grooves by engaging and to be applied against the inner face of the wall of the casing, the functional positioning of the plug receiver is realized in a simple and safe way,

  Each tab of the plug connector of the

  practically a snap in return of the tongue of

  FILING. This has the consequence that a replacement plug-in tab can not be sufficiently anchored in the plug receiver. This disadvantage is avoided when it is provided, in accordance with the invention, that each plug tab with the connecting conductor, is immobilized

  in a sheet of insulating material and that this sheet is sus-

external part.

  Providing that a protuberance protrudes on the outer face of the plug and that this protuberance is housed in a cavity in the orifice of the plug receiver,

  we obtain a simple engagement of the plug.
