Definitions

  • the present invention relates to an electro-fluidic (electropneumatic or electro-hydraulic) connector.

  • a mixed electrofluidic connector characterized in that it has the structure of a standard standard electrical connector for universal use of the type comprising two connection elements which can be coupled to each other and each comprising a piece of insulating material having two parallel faces and traversed right through by a plurality of bores axially perpendicular to said faces, each of these bores being able to receive a male or female type connection pin, so that, during the coupling, the male pins of one of the two insulating parts can engage in the female pins of the other part and vice versa, at least one of the holes being able to receive either an electrical connection pin or fluidic, these two pins having an external conformation at their passages in the insulating parts and each comprising autonomous fixing means engaging on corresponding conformations of the insulating part to ensure axial locking in both directions of said pin in its bore, the fluid connection pin consisting of a tubular sleeve male or female, the male sleeve having a cylindrical front portion capable of engaging in a co
  • the connector according to the invention has many advantages. Its cost is low because it is achievable using simple geometry parts (which is that of standard connectors already produced in large quantities). Its size is reduced since the mechanical structure is common to the electrical and fluidic functions.
  • the seals between the male and female sleeves are provided on the male sleeves. They are therefore accessible from outside the equipment and are suitable for automatic mounting.
  • the production of these connectors is simplified since they do not include any specific mounting linked to the pneumatic function and since the fluid connection pins are interchangeable with the electrical connection pins.
  • the end user of connectors of this type can configure a standard electrical connector himself, either into an electrical connector or into an electrofluidic connector. This operation is carried out very simply, without specialized tools.
  • the means for fixing the pins in the insulating parts include axial abutment means in one direction and an annular groove provided with elastic means allowing sliding in said direction and ensuring axial locking in the other direction.
  • said stop means are provided for blocking the pin in the insulating part in the direction of coupling, the above elastic means being provided in the rear part of said pins.
  • the pins according to the invention are introduced into the insulating parts by the front face of each of the latter, said abutment means being constituted by an annular flange which comes to bear against said anterior face, said annular groove being formed in a posterior part opposite to said anterior part.

  • the pins 29 and the sleeves 34 can be arranged in a bore 5, 6 or in the other at the option of the user, without this requiring any adaptation. the connector element and the tools used for mounting.
  • the female connection element 2 has, relative to the male connection element 1, a thicker base 4, and a hoop 13 which extends from an anterior side of the flange 15, over a distance substantially equal to the width of the annular collar 26.

  • This portion 49 has axial abutment means which may consist of a flange 51 which is fitted into a bore of complementary shape formed in the edges of the anterior opening of the bore 8.
  • the portion 49 comprises behind the connection zone, an annular groove 50 coaxial serving to enclose means for fixing the spindle on the base 4.
  • These fixing means can consist, for example, of washers or clips elastic 50 '( Figure 2) which come into abutment against an annular shoulder 53, ensuring the axial locking of the spindle 48 in the bore 8.
  • This shoulder is produced by a bore of a limited portion of the bore 7.8, which avoids introducing radial play in the retention of the pins in the holes.
  • a female type pneumatic connection sleeve 55 is arranged, the shape and external dimensions of which are similar to those of the pin 48.
  • this sleeve 55 comprises a tubular portion 56, housed in the bore 7 of the base 4 and which comprises a cylindrical bore 57 substantially at the outside diameter of the front part 37 of the sleeve 34 which it is supposed to receive .
  • the difference in diameter of the portion 56 and of the groove 38 ensures the compression of the O-rings 39.

  • the rear part 58 of the pin 55 which emerges from the rear face 19 of the base 4 has annular ribs 59 and constitutes a sealed connection end piece for a flexible conduit 60.
  • connection sleeve 55 is traversed by an axial channel 61 serving to convey the compressed air (or the vacuum).
  • the pins and the female sleeves 48, 55 can be arranged in a hole 7, 8 or in the other, at the option of the user without this requiring a any adaptation of the connector element, or specialized tools used for mounting.
  • connection elements 1, 2 With the aid of the two connection elements 1, 2 described above, the electrical and pneumatic connections are obtained at the same time, by engaging these two elements 1, 2 into one another after a movement in translation axial of one of the elements with respect to the other.
  • connection pins whether electrical or fluid, are introduced into the bases 3,4 by their front faces 16,18, owing to the fact that the forces exerted on these pins during the coupling of the two connection elements 1, 2 are larger than during uncoupling. Indeed, during coupling, centering forces of the male pins are exerted in the female pins, which are added to the friction forces between them. This is why, 32.51 flanges of axial abutment are provided on the front part of the pins, and lighter fixing means, namely, elastic conical washers 31.50 'housed in an annular groove 36.50 on the back of these pins.
  • the number of large diameter holes 5, 6-7, 8 could be greater than two, these holes being able to receive a number of electrical connection pins 29, 48 or of pneumatic connection sleeve 34, 55 adapted to user needs.
  • the holes of smaller diameter 9, 10 and the corresponding connection members 24, 27 can optionally be omitted.

  • the male connection element 70 comprises a base 64 of circular shape fixed in a cylindrical socket 72, the part which delimits the coupling volume has a thread 72 '.
  • This base 64 comprises a plurality of small diameter holes uniformly distributed on a circle concentric with the base as well as two larger diameter holes slightly offset relative to the longitudinal axis of the element 70.
  • the small diameter holes serve to the fixing of electrical connection pins of male type 67, similar to those previously described, while the holes of larger diameter are used indifferently for the assembly of electrical connection pins for relatively high powers (or even coaxial or triaxial pins) or pneumatic connection sleeves.
  • the larger diameter bore is assigned to a male connection sleeve 66 similar to the sleeve 34 previously described.
  • the female connection element 71 comprises a base 65 of cylindrical shape which is itself fixed in a cylindrical socket 73, the front part 75 of which has a diameter slightly less than the inside diameter of the front part of the socket in which it must to commit.
  • this sleeve 73 is rotatably mounted coaxially but axially retained thereon, a nut capable of being screwed onto the threaded outer surface of the sleeve.
  • the base 65 comprises a multiplicity of small diameter bores inside which are fixed female type electrical connection pins 69 intended to receive the male type connection pins 67 of the connection element 70.

  • the pins are introduced into the holes 5.7 by the rear face 17.19 of the bases 3.4 and are applied against an axial stop 83 located at the anterior opening of the holes 5.7.
  • the user can, using a conventional tightening tool, modify the configuration of the connector, by replacing electrical pins with fluidic pins or vice versa.
  • the connector comprises two bases 93, 94 made of electrically insulating material, having identical minimum thicknesses, each being provided with four cylindrical bores in which are housed electrical connection pins 101, 104, 101 ′, 104 ′ and fluid 102,103, 102 ', 103', the pins of the first base 93 being intended to engage simultaneously in the pins of the second base 94.
  • the bores 92 of the female pins 101 'to 104' extend substantially over the entire thickness of the bases 93.94.
