  • the electrical plug is then free to penetrate deeper into the socket 1, until its base comes to bear against the front face of the movable flap 170 and pushes the latter towards its depressed position (see figures 7 and 9 ).
  • the electrical plug is then free to penetrate deeper into the socket 1 until its pins engage in the cells 21, 31 of the phase and neutral terminals 30.
  • the rear shutter 60 remains attached to the housing 10, in that the cassette 80 holds it in position to ensure the electrical safety of the plug 1.
  • the shutter before 150 remains integral with the hubcap 100, which facilitates the disassembly of the latter.
  • the hubcap is devoid of movable flap.
  • the front shutter can then for example be secured to the hubcap by a cassette snapped to the rear of the bottom of the receiving well.
