Definitions

  • the present invention relates to an adapter, in particular USB charger type.
  • An adapter is a device that resolves connectivity incompatibilities by connecting two elements that are not designed to connect to each other.
  • a VGA-HDMI adapter allows you to connect a device that only has a VGA output to a TV that only has an HDMI input.
  • the adapters commonly known as “chargers” are a particular category for connecting equipment such as a telephone (usually with only a proprietary connector) to an electrical outlet for recharging.
  • USB chargers are used to power USB ports to which you can connect most of the cables of smartphones or tablets. They present a wide variety of appearances.
  • the present invention thus relates to an adapter comprising a first piece and a second piece respectively comprising at least one first connector and at least one second connector, the at least one first connector of the first piece being connected to the at least one connector.
  • the present adapter is a flexible adapter allowing a simple and robust structure to move from an "aligned" position to a "right angle” position.
  • minimum space and maximum accessibility including outlets behind furniture (in a charger operation) by varying the angle of rotation.
  • USB charger type adapter for smartphone or tablet.
  • the present invention relates to an adapter 1 comprising a first part 10a and a second part 10b respectively comprising at least a first connector 11a and at least a second connector 11b.
  • adapter is meant as explained a device for connecting a device having the first connector 11a to a device having the second connector 11 b.
  • a connector is female (by convention the first connector 11a) and the other connector is male (by convention the second 11 b), but it will be understood that it is quite possible to have two female connectors or two male connectors.
  • the adapter 1 is a charger, that is to say that the second connector 11 b (the male connector) is an electrical "plug", ie a male electrical socket, which can be inserted into a "base” Electrical, ie a typical female wall socket.
  • the type and form of electrical plug forming the second connector 11b may depend on national standards (electrical outlets vary by country).
  • the other connector 11a (female connector) is then advantageously a USB (Universal Serial Bus), widely available connectivity for smartphones and tablets.
  • USB Universal Serial Bus
  • the first piece 10a may include two or more USB ports. Having two USB ports allows not only to simultaneously load two devices, but is also very advantageous in the context of the present invention, as will be explained later.
  • Each connector 11a, 11b has an "orientation" that is to say a direction in which a complementary connector (male for a female connector, and vice versa) is inserted in (or is inserted by) this connection 11a , 11 b.
  • the adapter is in a position such that the orientation of each connector 11a, 11b coincides with the axis denoted AA '. If a part 10a, 10b comprises several connections 11a, 11b identical, they advantageously have the same orientation.
  • the two parts 10a and 10b are the two parts of a housing of the adapter 1. These two parts can be of any shape and any material, for example plastic. Both pieces present each advantageously an elongated shape with an invariance by translation (for example cylindrical or prismatic, the example shown in the figures has a hexagonal section) along a main axis of the part 10a, 10b, axis coinciding preferentially with the orientation of the connector 11a, 11b, in this case the axis AA 'on the figure 1 which in this particular case forms a common axis.
  • the first and second parts 10a, 10b are movable relative to each other.
  • the figure 1 therefore represents a particular position, said first extreme position, which has as explained an alignment of the parts 10a and 10b such that the main axes of these parts 10a, 10b are aligned, and thus such that the orientations of the first and second connectors 11a, 11b substantially coincide.
  • the adapter 1 then has a main axis AA '.
  • the first and second parts 10a, 10b have faces Fa, Fb complementary bevelled in contact.
  • beveled is meant that a face Fa, Fb of a part 10a, 10b is not orthogonal with respect to the main axis of the part 10a, 10b and / or with respect to the orientation of the connector of the part 10a, 10b.
  • planar faces may be complementary, a convex face and a concave face may be complementary, etc.
  • the faces define an axis of rotation BB 'of the first piece 10a relative to the second piece 10b.
  • this axis BB ' is orthogonal to a plane 2 ("plane of rotation") corresponding to the plane of contact between the faces Fa and Fb.
  • plane of rotation a plane 2
  • the adapter may comprise a cavity 13 (whose main utility will be seen later), forming a hollow axis of the adapter 1.
  • the cavity 13 may extend along the axis AA ', in the middle of the adapter 1.
  • One of the two parts 10a, 10b may have a cylindrical pin protruding from its face Fa, Fb inserted in the cavity 14 and forming the point of intersection between the axis of rotation BB 'and the plane 2 .
  • the figure 3 represents for example an embodiment of the first piece in which the cavity 14 is seen in the middle of the face Fa, the cavity 14 can receive the lug.
  • the lug may be provided at its end with a retaining clip, and the complementary face of a groove: the parts 10a, 10b can thus be “clipped” into each other (and possibly thus present a function limitation of rotation which will be described later).
  • the specificity of the rotation of the first piece 10a with respect to the second piece 10b is in the bevelled aspect of the faces Fa, Fb.
  • the associated angle which is clearly visible on the figure 1 , that the axes AA 'and BB' are distinct.
  • the angle of the bevel is 45 °, which corresponds to an angle of 45 ° between the main axis of the adapter 1 in the first extreme position (axis AA ') and the axis of rotation BB '.
  • the orientation of each of the first and second 11a, 11b is distinct from the direction of the axis of rotation BB '.
  • the axis BB ' is thus such that a rotation along said axis BB' causes a change of orientation of the at least one first connector 11a of the first piece 10a relative to the at least one second connector 11b of the second piece 10b. Indeed, if the faces Fa, Fb were for example each orthogonal to the main axis AA ', the rotation around the axis BB' would only cause a rotation of a connector 11a, 11b (relative to the other connectivity 11 a, 11 b) around its own axis.
  • the axis BB ' is the only axis of rotation of the adapter 1, in other words the single axis of rotation of the first part 10a relative to the second part 10b. This ensures a simple and robust adapter structure, as opposed to possible structures such as spherical or cardan.
  • the figure 2 represents an alternative position in which a rotation of about 180 ° about the axis BB 'has been implemented. This position is called the second extremal position and corresponds to the furthest position from the first extremal position. If a user continues the rotation, the adapter 1 to return to the first extremal position ( figure 1 ), unless the adapter 1 comprises means 20 for limiting the rotation of the first part 10a relative to the second part 10b (which will be described later).
  • the change of orientation of the first connector 11a compared to the second connector 11b is of the order of 90 °.
  • the first extremal position can thus be a "right" position of the adapter 1 with a minimal bulk (which allows for example easily carry the adapter to the bottom of a well-filled bag), and the second extremal position a "right angle" position offering maximum accessibility even for grips stuck behind furniture.
  • the first connector 11a of the first part 10a is connected to the at least one second connector 11b of the second part 10b via a flexible conductive element 13, such as one or more electrical cables.
  • This conductive element 13 is disposed (that is to say it has at least one extending portion) in the cavity 14, which gives it room to deform during rotation. We see in fact on figures 1 and 2 the difference in shape of this conductive element 13 according to the position of the adapter 1.
  • Each piece 10a, 10b may comprise a circuit 12a, 12b complementary to the connector 11a, 11b providing if necessary electronic functions for the adaptation of the electrical signal of a connector 11a, 11b to the other.
  • the conductive element 13 connects in particular these two circuits 12a, 12b.
  • the conductive element 13 is flexible but has a limited resistance, which is why it is necessary to avoid laps in a vacuum (a rotation of more than 360 ° could twist and then break this element 13).
  • the rotation limiting means 20 make it possible to protect the latter.
  • the means 20 for limiting the rotation limit the rotation about the axis BB 'between the first and the second extremal position.
  • these means limit the angular range of rotation, and to return to the first extremal position from the first extremal position it is necessary to carry out a rotation in the opposite direction to that which made it possible to reach the second extremal position. This unravels the conductive element 13, and prevents complete turns.
  • the means 20 may consist of the groove mentioned above: provided to limit it to a portion of the complete circle (in particular 180 °, as explained above), the rotation is limited when the lug abuts against the side of this groove.
  • the means 20 may consist of the groove mentioned above: provided to limit it to a portion of the complete circle (in particular 180 °, as explained above), the rotation is limited when the lug abuts against the side of this groove.
  • Those skilled in the art will know how to use many other systems as well to allow rotation as to limit it.
