  • the means 60 for raising the piston 50 do not present any risk of interference with the connection terminals 40 of the socket outlet 1.
  • the means 60 for raising the piston 50 more specifically comprise at least one compression spring 61; 63 which extends along the axis of translation of the piston 50 (see figures 2 , 3 and 19 ).
  • This compression spring 61; 63 has a rear end 62; 65 which bears against the front face 30A; 90A of the cover 30; 90, and a front end 64; 67 which bears against part of the piston 50 (see figures 3 and 19 ), so that said compression spring 61; 63 is interposed between the cover 30; 90 and the piston 50 to permanently push the piston 50 back to its high position.

  • a rear portion of the spring is housed in a housing 37 of the cover 30 which keeps it in place even when it is compressed (see figure 3 ). More precisely, the cover 30 carries a cylindrical sleeve 38 which extends forward and laterally delimits the cylindrical housing 37 (see figures 2 to 4 ) receiving the rear portion of the compression spring 61.

It has a cross section, in a plane perpendicular to said axis of revolution R, the diameter of which is practically equal, apart from play, to the internal diameter of said cylindrical wall 22, so that said compression spring 63 is a peripheral spring which runs along the internal face 22A of the cylindrical wall 22 .
  • the compression spring 63 according to this second embodiment is close enough to the cylindrical wall 22 so as not to risk moving or off-axis when it is compressed.
  • This configuration makes it possible to have great stability during the displacement of the piston 50. It is then not necessary to provide special arrangements making it possible to guide or hold in place the compression spring when it is compressed.
  • the cover 90 of the socket 1 according to the second embodiment is identical in all respects to the cover 30 according to the first embodiment except that it does not have a central housing intended to hold the spring compression in position during compression.

  • a spring is for example arranged around the openings of the cover allowing the passage of the ground pin or the access to the phase and neutral terminals, while being sufficiently distant from the cylindrical wall so as not to be able to bear against this last and use it as a guide when compressing. It is then necessary to provide on the cover a housing receiving the rear end of this spring, for example a cylindrical groove in which the rear end of the spring is housed, to prevent any displacement of the spring during its compression. A similar groove could be provided on the rear face of the piston wall to hold the front end of the spring in place during its compression.
  • the means for raising the piston include two compression springs which extend on either side of the axis of revolution of the cylindrical wall, and the respective rear ends of which are housed in two housings of the cover.

  • Each tab 82 of the locking wheel 80 also has a rounded angle 85 (see figures 15 to 18 ). This rounded angle 85 is intended to slide against said retaining surface 83 of the notch 84 to facilitate the disengagement of said tab 82 from the notch 84, when the shock occurring on the front face 50A of the piston 50 is of the IK7 type.
  • each tab 82 of the locking wheel 80 of the piston 50 is made of rigid plastic material, undeformable by an impact of IK7 type occurring on the front face 50A of the piston 50.
  • the tab 82 is automatically disengageable, it that is, it comes out of the notch 84 for an IK7 type shock, without breaking.
  • each notch 84 and the corresponding guide groove 26 is achieved by means of a ramp 27, that is to say of an inclined surface, forming a contact surface against which the tab 82 of the locking wheel 80 slides to be braked before it engages in said guide groove 26.
  • the contact surface formed by the ramp 27 is for example chosen to be concave, facing the front of the socket 1 (see figure 15 ). This shape makes it possible to further slow down the piston 50 before the lugs 82 of the locking wheel 80 engage in the guide grooves 26.
  • the length of the contact surface formed by the ramp 27 is such that, for an IK7 type impact, the speed of movement of the piston 50 in the guide groove 26 is strictly less than a threshold speed at which the piston 50 deteriorates the power outlet 1.
  • the junction between the notch 84 and the ramp 27 is smooth, without stopping or breaking.
  • the meeting line between the notch 84 and the ramp 27 is rounded and not angular. This configuration facilitates automatic disengagement of the locking means, the rounded tab 82 of the locking wheel 80 sliding more easily out of the notch 84 of the cylindrical wall 22.
  • the shutter 71 remains in the closed position.
  • the pivoting of the locking wheel 80 from its locking position to its unlocking position caused by the impact received on the front face 50A, does not cause the pivoting of the shutter 71 from its closed position towards its open position.
  • the return means 89 of the locking wheel 80 in the locking position is here formed by a compression spring 89 interposed between a bearing surface 89A of the cassette 70 and a bearing surface 89B of the locking wheel 80 ( see figure 6 ).
  • this compression spring 89 is housed in a housing delimited, at the front, by the sidewalk 79A of the cassette 70, at the rear, by the locking wheel 80, and, laterally, on the one hand, by a wall 87 extending at the rear of the sidewalk 79A of the cassette 70 and the curved end of which forms the bearing surface 89A of the cassette, and on the other hand, by the cylindrical wall 56 of the wall of piston 55, and the bearing surface 89B of the locking wheel 80.
  • the ramp communicating the notch and the guide groove has a flat surface instead of concave.
  • the surface of this ramp would then be coated with a non-slip coating to brake the piston before it arrives in the guide groove.
  • the shutter is mounted in the movable cassette in translation along an axis orthogonal to both the translation axis of the piston and the axis oriented at 45 ° along which the receiving cells are aligned.
  • a mechanical system making it possible to transform a translational movement into a rotational movement would then be used between the shutter and the locking wheel so that the movement of the shutter from its closed position to its open position results, under conditions normal use, unlocking the locking wheel.
