Definitions

  • the present invention relates to a connector support device for internal combustion engine injectors.
  • This arrangement has a drawback of requiring multiple and complex assembly operations which are not capable of automation.
  • the present invention aims to overcome these drawbacks.
  • the subject of the invention is a device for supporting the connection of injectors of an internal combustion engine, characterized in that it comprises a mounting plate for its attachment to a rail of injectors, and a chute. for guiding the power supply cables to the injectors and for maintaining the connectors connecting said cables to said injectors, said chute being mounted on said plate, said connectors having a degree of freedom of oscillation around an axis parallel to the direction longitudinal of the chute with respect to said plate.
  • said chute can in particular be mounted on said plate by means of at least one hinge.
  • said connectors have a degree of freedom of translation parallel to the longitudinal direction of the chute with respect to said plate.
  • the connectors can in particular be maintained on a bottom wall of said chute by a bayonet mount forming an elongated hole in the longitudinal direction of the chute.
  • the degrees of freedom thus provided allow relatively wide tolerances, both at the level of the fixing of the plate on the injector rail, and at the level of the mounting of the chute on the plate.
  • FIGS. 1 to 10 we can see a device according to the invention, essentially consisting of a plate 1 and a chute 2 connected by hinges 3.
  • the plate 1 has holes 4 for fixing it using bolts 5 to a rail of injectors.
  • the hinges 6 and the pins 7 extend in the longitudinal direction plate 1 and chute 2.
  • the chute 2 therefore has a degree of freedom of rotation around the pins 7, which can for example be fixed at ten degrees.
  • the chute 2 receives at one of its ends a supply connector 9, while connectors 10 for connection to the injectors are fixed outside of the chute 2 on its bottom plate 11.
  • This fixing is provided by a bayonet mount (not shown in Figure 2) consisting of a pin 12 secured to the connector 10, and provided with ears 13 capable of engaging in cutouts 14 formed at the periphery of holes 15 formed in the bottom wall 11 of the chute 2.
  • the pin 12 of the connector 10 is therefore engaged in the hole 15, perpendicular to its final position, then is turned a quarter of a turn to be put in place and maintained in this position.
  • the holes 15 are in fact not circular but slightly elongated in the longitudinal direction of the chute 2, so as to give the connectors 10, when in place, a degree of freedom of translation parallel to the longitudinal direction of the device.
  • the connectors 10 are connected to the connector 9, by supply cables 16 (not shown in FIG. 2) arranged in the trough 2 and covered by a cover 17.
  • the plate 1 ' is made of plastic, the hinges 6' being made in one piece with this plate.
  • the fixing holes on the injector rail are provided with metal inserts 18 put in place by overmolding.
