Definitions

  • the invention relates to a set of electrical sockets comprising an electrical plug and a base adapted to collaborate with each other removably.
  • Said plug has at least two concentric annular electric tracks intended to collaborate respectively with electrical contacts of the electrical base.
  • Magnetic control means generates a first control force for positioning and holding the plug on the base so that the annular tracks are respectively in contact with the electrical contacts of the base.
  • 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.
  • EP2128936 also discloses the use of magnetic means for positioning and holding a plug on an electrical base as claimed in the preamble of claim 1.
  • the magnetic means are also able to move electrical contacts of the electrical base so as to ensure a 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 document US3521216 describes an electrical base where the electric tracks are not in grooves.
  • the base has electrical tracks that are no longer energized when the plug is removed from the base.
  • the base then has movable electrical contacts placed inside said base and not accessible. Said electrical contacts are intended to connect to the electrical tracks only when the plug is in contact with the base. The risk of electrocution is reduced when the plug is not connected to the base.
  • the electrical tracks of the base although not electrically connected are apparent. This can have two disadvantages. On the one hand, it is not recommended by the standards to have direct access to electrical tracks intended to be powered. On the other hand, in the event of malfunction of the mechanism allowing the moving electrical contacts to move from a position connected to an unconnected position, the tracks of the base may be energized even though the plug is removed.
  • the invention therefore aims to overcome the drawbacks of the state of the art, so as to provide a set of electrical plugs capable of providing a secure electrical connection between the base and the electrical plug as claimed in the independent claim 1 and the claims. related dependencies.
  • the base of the set of electrical sockets comprising one comprises at least two movable electrical contacts that can move between a first position inside the base and a second position outside said base to be respectively in direct electrical contact with the electrical tracks of the electrical plug, said first control force being able to move the electrical contacts between the first position and the second position.
  • the base comprises elastic control means generating a second displacement force of lower intensity and opposite direction to the first control force, said second displacement force being able to move the contacts. between the second position and the first position.
  • the base comprises shutter means able to pass from a closed position to an open position under the action of the first control force to let the electrical contacts of the first in the second position.
  • the magnetic control means comprise at least a first magnet integrated in the plug and at least one movable magnetic element integrated in the base.
  • the electrical contacts are integral with the magnetic element so that the first control force simultaneously moves the movable magnetic element and the electrical contacts between the second position and the first position.
  • said at least first magnet and said at least one magnetic element are annular.
  • said at least one magnetic element comprises a magnet.
  • the concentric annular electric tracks are electrically insulated from one another.
  • the shutter means respectively comprise two shutter flaps, each shutter shutter being connected to a closing spring.
  • the plug and the electrical base respectively comprise an electrical contact intended to be connected to a grounding.
  • the base comprises contact pressure springs connecting the electrical contacts to the magnetic element.
  • the set of electrical outlets 1 having an electrical plug 10 and base 20 adapted to collaborate with each other removably.
  • said electrical plug comprises a body comprising at least one substantially flat contact face.
  • said electrical base 20 comprises a body 25 having at least one substantially flat contact face. The contact faces of the base 20 and the plug 10 are intended to be placed in contact with each other when said plug is assembled to said base ( figure 4 ).
  • the plug 10 comprises at least two electrical tracks 11, 12 disposed on the contact face of said plug.
  • Said electrical tracks are preferably annular and concentric.
  • said tracks are electrically insulated from each other.
  • the electric tracks 11, 12 are connected to electrical wires 17 and are designed to collaborate respectively with electrical contacts 21, 22 of the electrical base 20.
  • the electrical plug 10 preferably has an electrical contact 14 to be connected to a ground.
  • This earth electrical contact 14 is positioned at the center of the two concentric annular tracks 11, 12.
  • the set of electrical outlets 1 comprises magnetic control means 13, 23 generating a first control force for positioning and holding the plug 10 on the base 20 so that the annular tracks 11, 12 are respectively in contact with the electrical contacts 21, 22 of the base 20.
  • the magnetic control means 13, 23 comprise at least a first integrated magnet 13 in the plug 10 and at least one movable magnetic element 23 integrated in a housing 25 of the base 20.
  • said at least one movable magnetic element 23 comprises a metal ring made of a magnetizable material.
  • said at least one movable magnetic element 23 comprises a magnetized zone preferably having a annular form.
  • the first control force is increased relative to that obtained in the first particular embodiment.
  • the magnetic element 23 and the magnet 13 are attracted to each other which causes a sudden positioning and holding the plug 10 on the base 20.
  • Said at least first magnet 13 and said at least one magnetic element 23 are preferably annular. In addition, they are respectively disposed on the periphery of the contact faces of the plug and the base so that the first control force is better distributed to improve the accuracy and efficiency of the positioning and maintenance of the plug on the base 20.
  • the base 20 comprises at least two electrical contacts 21, 22 intended to be connected to unrepresented electrical wires.
  • the electrical contacts 21, 22 are integral with the magnetic element 23 placed inside the housing 25 of the base 20.
  • Said at least two electrical contacts 21, 22 are movable and can move concomitantly with the magnetic element 23 between a first position inside the base 20 and a second position outside the base to be respectively in direct electrical contact with the electrical tracks 11, 12 of the electrical plug.
  • the flat contact face of the base 20 has openings 27 through which the electrical contacts can pass.
  • the electrical base 20 preferably has an electrical contact 24 intended to be connected to a ground.
  • This earth electrical contact 24 is preferably positioned in the center of the contact surface of the base to come into contact with the earth contact 14 of the electrical plug 10.
  • the electrical contacts placed in a first operating position are recessed relative to the contact surface of the base.
  • the first control force has no effect on the positioning of the electrical contacts because the plug 10 is remote from the base 20.
  • the electrical contacts 21, 22 are held in this position inside the housing 25 of the base by elastic control means 28 generating a second control force.
  • the elastic means 28 comprises a spring.
  • the second control force is of lower intensity and opposite direction to the first control force.
  • the intensity of the first control force becomes greater than that of the second displacement force.
  • the first displacement force acts directly on the magnetic element 23 and causes its displacement from the first to the second position.
  • the electrical contacts 21, 22 are then displaced between the first position and the second position. Said first control force is thus able to move the electrical contacts 21, 22 between the first position and the second position.
  • the first displacement force becomes less than the second displacement force which is able to move the electrical contacts 21, 22 between the second position and the first position.
  • the base 20 of the electrical outlet assembly 1 comprises shutter means 26.
  • Said shutter means are positioned in front of the openings 27 through which the electrical contacts can pass.
  • the shutter means 26 are able to pass from a closed position to an open position under the action of the first control force to let the electrical contacts 21, 22 from the first to the second position.
  • the opening of the shutter means 26 is caused by a thrust of the electrical contacts 21, 22 on said shutter means 26.
  • the shutter means 26 are returned to a closed position under the action of force generated by closing springs 29.
  • the shutter means 26 of each opening respectively comprises two shutter flaps. Each shutter shutter is then connected to a closing spring 29.
  • the base 20 comprises contact pressure springs 30.
