Definitions

  • the invention relates to rotary sockets.
  • the invention also relates to power supplies comprising such rotary plugs.
  • US2011 / 0312194 A1 reveals a socket housing with plug inserts provided with a rotatable portion and a fixed portion secured to the housing.
  • the moving part is equipped with flexible wires which pass through a hole in the fixed part and which are electrically connected to the electrical connection lines present inside the housing. Stoppers limit the amplitude of the rotation.
  • the device unveiled by US2011 / 0312194 A1 nevertheless presents weaknesses in the electrical connections between the flexible wires and the electrical connection lines in the housing and the plug contacts. Indeed, during the rotation of the plug insert, mechanical stresses are exerted on these electrical connections, which, in the long run, causes the breakage of these connections.
  • EP0768737 A1 a socket block with rotating plug inserts with flexible wires. These flexible wires provide the connection between the electrical connection poles of the block and the sleeves of the plug inserts for receiving the pins of electrical plugs.
  • the grounding of each insert is also connected to the corresponding pole of the block by means of flexible wires.
  • the sleeves and the grounding of each insert are not connected directly to the corresponding poles of the block, but the electrical connection is made by an interconnection between the sleeves (and the earth) of the various plug inserts via flexible wires .
  • the connecting wires In order for each socket insert to have independent rotational movement, it is necessary for the connecting wires to be considerably longer in length than the direct distance between two adjacent socket inserts.
  • EP0702433A2 also discloses a socket block provided with rotary plug inserts, the rotation of the inserts being this time made possible by an arrangement of sliding contacts between pads integral with the setting inserts and friction ring sections. Such a system provides a limited range of possible angles for the plug inserts.
  • CN201781169 discloses a system in which the electrical connection between the tap inserts and the terminal poles of the block is effected by contact between two conductive plates and the outer surfaces of the tap inserts. Such a system does not allow to connect a ground to the plug inserts.
  • An object of the invention is to allow easy connection of several electrical plugs on the same socket block, by a suitable rotation of each socket insert connected to an electrical plug, so as to prevent contiguous plugs interfering with each other .
  • Another object of the invention is to provide a block of robust rotary plugs whose mechanism can be solicited many times without causing damage to its structure and not endangering users.
  • the object of the invention is a rotary socket comprising a base and a movable part comprising a protective bowl and able to pivot in rotation relative to the base, mechanical means for limiting the amplitude of rotation, said base being provided with a passage, said movable portion being also provided with a passage and a plurality of conductive cells able to receive the pins of a male electrical plug, fixing means adapted to secure the base with a support, flexible electrical wires surrounded by an insulating sheath and electrically connected to said conducting cells, said flexible electrical wires passing through said passage of said movable portion and said passage of said base,
  • the passages in the base and the movable portion may have different sections, to the extent that the central portions of the conductive son are immobilized effectively.
  • the passages in the base and the movable portion have a circular section.
  • This shape for the section is particularly suitable for flexible electrical son of circular section.
  • the passages of circular section have a diameter such that they closely enclose the electrical son to maintain their central portion substantially immobile.
  • the electrical contacts of the fixed and mobile parts are arranged opposite each other, that is to say that the electrical connections between the flexible electrical wires and the conducting cells are made at the of the upper part of the movable part while the connections between the flexible wires and the conductive pads are made at the bottom of the base.
  • This configuration for the electrical contacts makes it possible to lengthen the portion of the flexible electrical wires substantially parallel to the axis of rotation of the mobile part.
  • the socket according to the invention is further provided with a safety device preventing the user from indiscriminately accessing the conducting cells ("child" safety).
  • a safety device preventing the user from indiscriminately accessing the conducting cells ("child" safety).
  • Such a device can take different embodiments, the objective being each time to prevent unexpected access to the conductive cells that could cause inconvenience such as electrocution.
  • the electrical connections are made by welding.
  • the flexible electrical son are crimped at both ends. Crimping is an advantageous alternative to welding because it guarantees an extended service life and eliminates the low point resulting from high temperatures in the case of welding.
  • the electrical connections are made by screwing.
  • Another object of the invention is a power strip comprising at least one rotary power socket according to the description above.
  • the total number of rotary power outlets on the power strip depends on the needs of the user.
  • the power strip is provided with both rotary sockets according to the present invention and conventional non-rotating sockets. It is indeed not essential in some cases that all power strip sockets are rotatable and the number of rotating sockets can be restricted in order to reduce costs, a rotary socket being more expensive to design than a socket classic.
  • the location of the rotary plugs can be chosen in various ways.
  • the rotary plugs are at both ends of the power strip.
  • the rotary sockets are alternating with conventional sockets on the power strip, thereby reducing the mutual annoyance generated by each pair of contiguous plugs.
  • Another object of the invention is a socket block adapted to be integrated into a wall comprising at least one socket as described above.
  • a socket block with both rotating sockets according to the present invention and conventional non-rotating sockets can be realized.
  • the location of the rotary plugs can be chosen in various ways.
  • the figure 1 is an exploded view of the lower part of the rotary socket according to one embodiment of the invention. Flexible electrical wires are not shown in this figure.
  • the upper part of the rotating plug consisting of a protective bowl 22, is not shown here but is visible at the Fig. 4 .
  • a portion 2, movable in rotation, is inserted into a base 4.
  • a passage 6 passes through the movable portion 2 at its center (which corresponds to its axis of rotation) and a corresponding passage 8 passes through the base 4.
  • the moving part 2 comprises conductive cells 10 adapted to receive the pins of a male electrical plug.
  • a conductive rod 12 for an electrical connection to a ground is also present on the movable portion 2.
  • Clamping means 14 for gripping the ends of the electrical son connected to the conductive cells 10 are located in close proximity to the cells.
  • Mechanical means 15, 16 for limiting the amplitude of rotation between the portion 2, rotatable, and the base 4 are present.
  • the figure 2 is an exploded view of the lower part of the rotary socket according to another embodiment of the invention.
  • This embodiment corresponds to the German standard used for sockets, commonly called "schuko".
  • the difference compared to the previous embodiment is due to the connection structure of the earth electrode which in the latter case is no longer a conductive rod 12 but a pair of side tongues 13.
  • the similar elements common between the embodiment of the figure 1 and that of the figure 2 are denoted by similar references.
  • FIG 3 shows the top of the rotating part.
  • the elements of the rotating part described in the first paragraph appear in more detail in this figure.
  • the figure 4 shows the bottom of the rotary socket.
  • the base 4 is provided with conductive pads 17.
  • Stalling means 18 adapted to grip the ends of the electrical wires connected to the conductive pads 17 are also present on the base 4.
  • the passage 8 has a circular shape and its diameter is such that it tightly tightly grips the electrical wires (not visible in this figure) passing therethrough so as to keep them substantially immobile during the rotation of the rotary portion 2. It will be noted that the passage 8 may have different sections, to the extent that the conductors son are maintained in the same way.
  • the figure 5 is an exploded view of a rotary socket according to the invention.
  • the protective bowl 22 consisting of a ring preventing contact with a live part and a perforated bottom for the passage of the pins.
  • This bowl is integral with the movable part in rotation 2.
  • a safety device can be integrated in this bowl 22 ("child safety").
  • the figure 6 shows in more detail the zone of the part 2 where the conductive wires 24 are electrically connected.
  • the electrical connections 26 are made by welding. In other embodiments, the electrical connections can be made by crimping.
  • This figure highlights the effect of the wedging means 14 on the conductive wires 24.
  • the wedging means 14 enclose the ends of the conductor wires 24 so as to reduce strongly or even eliminate any mechanical stress at the electrical connections 26 when a rotation of the moving part.
  • the angle formed by each conductor wire at the passage 6 also contributes to the elimination of the mechanical stresses exerted on the electrical connections when the part 2 makes a rotational movement with respect to the base 4. This is particularly important when the contacts are welded because the welds are rigid connections very sensitive to mechanical stresses.
  • the figure 7 shows in more detail the zone of the base 4 where the electrically conductive wires 24 are electrically connected.
  • the wedging means 18 enclose the ends of the conductive wires 24 in order to reduce or even eliminate any mechanical stress at the level of the wires. Electrical connections 28.
