Definitions

  • the present invention relates to a through type electrical connector enabling fluidtight passage of electric signals, supplied by one or more conducting wires, through a partition, in particular, a panel of a gearbox or any other mechanical vehicle component.
  • US-A-3 350 587 discloses a fluidtight electrical connector for a submersible electric motor, comprising a plastics plug fitted in a hole in the wall of the motor.
  • Said wiring provides for two functions: (1) for picking up electric signals produced by pressure, temperature or level sensors, etc. which, if they are to operate correctly, must be installed inside the component itself; and (2) for supplying the component with electric control signals for actuators such as continuous gear shift control electrovalves.
  • the aim of the present invention is to provide a through type electrical connector designed to enable complete preassembly of the mechanical components of a vehicle, through one panel of which an electric signal is to be supplied, while at the same time ensuring permanent fluidtight sealing of the mechanical component itself.
  • Number 1 in Fig.s 1 to 4 indicates a through type electrical connector enabling fluidtight passage of electric signals, supplied by one or more conducting wires 2, through a panel 3 of any type of mechanical component, e.g. a known gearbox 4 (shown only partly),of any known type of vehicle (not shown).
  • a known gearbox 4 shown only partly
  • Connector 1 is fitted in externally projecting manner on to gearbox 4 through a hole 5 in panel 3, and comprises a cylindrical block 6 housed in projecting manner through hole 4; and a lock coupling 7 for block 6, bayonet-connected to block 6 and, like the latter, preferably molded from synthetic plastic material.
  • Block 6 presents two opposite front ends 8 and 9 designed to cooperate respectively with coupling 7 and with hole 5 and the inner surface 10 of panel 3, and houses respective ends 12 of wires 2 and respective terminals 13 of the same molded inside block 6 so as to form one piece with the same.
  • Said end 9 comprises a peripheral stop flange 15 designed to contact surface 10 about hole 5, the remainder of end 9 being housed, in use, inside hole 5 and plugging the same in fluidtight manner by virtue of an annular O-ring type seal 18 housed inside a groove 19 formed on an outer cylindrical lateral surface 20 of end 9 close to flange 15.
  • Block 6 is axially longer than the thickness of panel 3, so that, in use, end 8 projects axially through hole 5 in relation to the outer surface 21 of panel 3, opposite surface 10.
  • Wires 2 project in fluidtight manner from end 9, whereas, from end 8, there project axially, in fluidtight manner, respective blade type contacts 22, each connected to a respective terminal 13 and to a respective wire 2 via said terminal 13.
  • the non-limiting embodiment shown presents two wires 2 and two contacts 22 arranged side by side, said contacts 22 being separated by a projecting, transverse rib 23 formed on end 8 and integral in one piece with block 6, so as to electrically insulate wires 2 both from each other and from panel 3.
  • Coupling 7 comprises a first substantially-cylindrical annular end portion 25 designed, in use, to fit on to the projecting portion of end 8 of block 6, and terminating in an elastically-deformable, flared, truncated-cone-shaped annular edge 26 designed, when elements 6 and 7 are connected, to cooperate in contacting manner with the outer surface 21 of panel 3, and defining the mouth of coupling 7 towards end 8 of block 6.
  • Coupling 7 also comprises a second annular end portion 27 opposite end portion 25, and similar in design to the outer portion of a Pakard connector, i.e. in such a manner as to receive in fluidtight manner an electric plug 28 designed to cooperate with contacts 22.
  • Plug 28 (shown by the dotted line) preferably presents deformable outer annular sealing elements 40 designed to cooperate internally with portion 27; and an outer stop element 41 designed to click on to an outer projection 42 of portion 27 of coupling 7, which, together with end 8 of block 6 housed inside the same, defines a standard Packard connector.
  • wires 2 projecting from end 9 of block 6 are connected to the sensors and/or actuators on gearbox 4 with which electric signals are to be exchanged.
  • Block 6 is then fitted through hole 5, so that end 8 supporting projecting contacts 22 projects from hole 5, which is plugged in fluidtight manner by end 9 by virtue of seal 18 and flange 15.
  • End 8 extending outwards of surface 21 beyond hole 5 is then fitted with bottom end 25 of coupling 7 by engaging teeth 30 inside grooves 31.
  • coupling 7 is fitted axially on to end 8 and pushed towards end 9, flexible edge 26 contacts surface 21 just before teeth 30 come to the end of grooves 31. Further pressure is then exerted on coupling 7, either manually or by means of a robot, so as to flex edge 26 and enable teeth 30 to slide to the end of grooves 31.
  • Coupling 7 is then turned so as to slide teeth 30 into the transverse portion of L-shaped grooves 31, and into the angular position corresponding to recesses 34.
  • O-ring seal 18 is housed in an annular seat consisting of a groove 50 formed on a front surface 51 of flange 15 facing end 8 of block 6, i.e. with the surface of flange 15 cooperating directly with inner surface 10 of panel 3.
