  • Said electrical plug comprises at least two electrical tracks and said base comprises at least two movable electrical contacts able to move between an internal position and a position external to said base.
  • the set of electrical outlets comprises magnetic control means comprising a first magnet integrated in the plug, and a movable magnetic element integrated in the base and secured to the electrical contacts.
  • the first magnet generates a control magnetic flux attracting the movable magnetic element and displacing the electrical contacts between the internal position and the external position.
  • the control force of the magnetic means of the set of electrical outlets is sufficient to exert an attraction of the plug on the base when the latter is positioned in an environment close to the base.
  • the control force also keeps the plug on the base in the connected position.
  • the document EP2128936 also describes the use of magnetic means for positioning and maintaining a plug on an electrical base.
  • the magnetic means are also able to move electrical contacts of the electrical base so as to provide an electrical connection between the electrical plug and the base.
  • the electric tracks of the base and / or the electrical plug are generally positioned inside more or less deep grooves and more or less narrow.
  • the presence of these grooves requires an axial positioning of the plug facing the base so that the contact is easily achievable.

  • the body of the second portion 33B of the magnetic yoke 33 has a substantially cylindrical shape.
  • the first control force F1 has no effect on the positioning of the electrical contacts 21, 22 because the plug 10 is remote from the base 20.
  • the electrical contacts 21, 22 placed in the internal position are set back by relative to the contact surface of the base 20.
  • the electrical contacts 21, 22 are held in this position inside the housing 25 of the base 20 by elastic control means 28 generating a second control force F2.

  • the electrical contacts 21, 22 can remain in the external position after the plug 10 is removed from the base 20.
  • the presence of the magnetic yoke 33 also makes it possible to provide a negative force called "retraction" of the movable contacts 21, 22 when the plug 10 is removed from the base 20.
  • the negative "return” force is added to the second force of control when the elastic control means 28 are operational.
  • this negative force is related to the circulation of a magnetic reentry flux ⁇ ren circulating preferentially between the second annular magnet 44 of the magnetic element 23 and the second part 33B in the magnetic yoke 33 and the sliding air gap E2.
  • the magnetic yoke 33 thus plays a dual role depending on the presence or absence of the plug 10 in contact on the base 20.
