Description

TECHNICAL FIELD OF THE INVENTION The invention relates to a set of electrical sockets comprising a plug and a base adapted to collaborate with each other removably. Said plug having at least two concentric annular electric tracks intended to respectively collaborate 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 electric tracks are respectively in contact with the electrical contacts of the base, the first control force being inversely proportional to the the distance between the electrical plugs and the base. The base comprises elastic control means generating a second control force in the opposite direction to the first control force and being able to move the electrical contacts between a second position outside said base and a first position inside. of the base, the second control force being of intensity less than the maximum intensity of the first control force. STATE OF THE PRIOR ART The use of magnetic means for positioning an electrical plug on an electrical base is known. Indeed, US7066739 discloses a set of electrical sockets having a plug and a base respectively having annular electric tracks intended to come into contact with each other under the action of magnetic means. The use of annular electric tracks allows undifferentiated / blind angular positioning of the plug on 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.
In addition, the control force also keeps the plug on the base in the connected position. EP2128936 also describes the use of magnetic means for positioning and maintaining a plug on an electrical base. As for US3521216, 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. To avoid the risk of electrocution by direct contact, the electric tracks of the base and / or the electrical plug are generally positioned within 10 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 narrower and deeper the grooves are, the more precise and restrictive axial positioning must be. This alignment and positioning constraint is all the more felt at the time of tearing of the grip. To remedy this problem, the document US3521216 describes an electrical base where the electrical 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. However, 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 energized. 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. Certain solution such as in particular described in the French patent application filed in the name of the applicant and entitled "Set of electrical sockets" present means securing access to the electrical contact during the passage of a position connected to a position unconnected (Figures 1 and 2). However the effectiveness of this type of solution is highly dependent on the direction in which the tearing of the plug is performed.
Indeed, as shown in Figure 4A, when the plug is removed in a direction that is not perpendicular to the contact plane between the plug and the base, the means securing access to the electrical contacts are not fully operational. Indeed, the plug may partially still be in contact with the base on a point of its periphery and be away from said base at a second point of its periphery. In this position, the live electrical contacts (connected position) are accessible by a user handling the electrical outlet assembly. As shown in FIG. 5, the curves of evolution of the force of attraction of the plug on the base are dependent on both the distance e between said plug and said base but also on the angle of tearing. of the plug in relation to the base. The distance e is substantially equal to the largest distance between a point of the circumference of the plug and the planar surface of the base in the Y direction. A first solid curve represents the evolution of the force of attraction F of the plug on the base according to the distance separating said plug and said base when the plug is removed in a direction perpendicular to the contact plane plug-base. The attractive force F becomes smaller than a control force Fdec recalling the electrical contacts in a disconnected position from a first separation distance e_dec-lin.
A second dotted line curve represents the evolution of said attraction force F when the plug is removed in a direction that is not perpendicular to the plug-socket contact plane. The attractive force F becomes smaller than the control force Fdec from a second separation distance e_dec-ang.
As shown in FIG. 5, the second separation distance e_dec-ang is greater than the first separation distance e_dec-lin. In addition, this e_dec-ang distance is such that a user can unintentionally reach the electrical contacts before they have moved to the disconnected position. SUMMARY OF THE INVENTION The invention therefore aims to remedy the disadvantages 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. The set of electrical sockets according to the invention comprises magnetic or mechanical means for the anticipated unlocking of the displacement of the two moving electrical contacts from the second position to the first position, said unlocking means being arranged to reduce the power ratio between the first control force and the second control force at the time of separating the plug from the base. Preferably, the magnetic control means comprise at least one first annular magnet integrated in the plug and at least one annular magnetic element integrated in the base.

Preferably, the annular repulsion magnets are greater in diameter than the diameter of the first annular magnet. According to a first embodiment of the invention, the mechanical unlocking means placed inside the base comprise a slider supporting the electrical contacts, said slider being guided in translation relative to the base. Said mechanical means comprise a hollow cradle supporting the annular magnetic element of the magnetic control means and having a base in which a bearing surface hemispherical of the slide bears, said cradle being able to move in translation and / or to pivoting towards the base to drive the slider and the moving electrical contacts between the second and the first position inside the base. The pivoting of the cradle causes a displacement of the hemispherical contact surface of the slide on the bottom of said cradle and a displacement of said slide in translation. According to one particular embodiment, the elastic control means comprises at least two return springs arranged symmetrically with respect to a longitudinal axis passing through the center of the annular magnetic element when the assembly is in the first or second position. , the springs respectively exerting traction forces on the cradle tending to place the electrical contacts in the first operating position. Advantageously, the set of taps comprises pressure means generating a pressing force maintaining a mechanical contact between the hemispherical support surface 30 of the slider and the bottom of the cradle.

DETAILED DESCRIPTION OF AN EMBODIMENT According to a preferred embodiment of embodiment as shown in FIGS. 1 and 2, the set of electrical outlets 1 comprising an electrical plug 10 and base 20 adapted to collaborate with each other. other in a removable manner. Said electrical plug 10 comprises a body 15 comprising at least one substantially flat contact face. Said electrical base 20 comprises a body 25 comprising 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 2). The plug and the base in contact forming a set of electrical outlets developing along a longitudinal axis Y. The plug 10 has 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 developing around the longitudinal axis Y. In addition, said tracks are electrically insulated from each other. The electrical tracks 11, 12 are connected to electrical wires 17 and are intended to collaborate respectively with electrical contacts 21, 22 of the electrical base 20. The electrical plug 10 preferably comprises an electrical contact 14 intended to be connected to a cable. taken from the 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 F1 for positioning 25 and holding the plug 10 on the base 20 so that the annular tracks 11, 12 are respectively in contact with each other. with the electrical contacts 21, 22 of the base 20. According to a development mode, the magnetic control means 13, 23 comprise at least one integrated first magnet 13 in the plug 10 and at least one movable magnetic element 23 integrated in a box 25 of the base 20. Said movable magnetic element 23 preferably comprises a magnetized zone preferably having an annular shape. Advantageously, said magnetic element 23 comprises an annular magnet intended to be placed vis-à-vis the first annular magnet 13 when the plug 10 is in contact with the base 20. According to an alternative embodiment, said at least one movable magnetic element 23 may comprise a metal ring made of a magnetizable material. When the plug is placed next to the base, the magnetic element 23 and the magnet 13 are attracted to each other which causes a sudden positioning and holding of the plug 10 on the base 20. Said least first magnet 13 and said at least one magnetic element 23 are preferably ring-shaped. In addition, they are respectively disposed on the periphery of the contact faces of the plug and the base so that the first F1 control force is better distributed in order to improve the accuracy and efficiency of positioning and maintaining the plug. 10 on the base 20. The base 20 comprises at least two electrical contacts 21, 22 for connection to electrical son. 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 20 concomitantly with the magnetic element 23 between a first position inside the base 20 (disconnected position) and a second position (connected position) outside the base to be respectively in direct electrical contact with the electrical tracks 11, 12 of the electrical plug. According to a particular embodiment, 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 earthed 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. As shown in FIG. 1, the electrical contacts 21, 22 placed in a first operating position (disconnected position), are set back relative to the contact surface of the base. The first control force F1 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 F2. According to one embodiment of the invention the elastic means 28 comprises a spring. The second control force F2 is of intensity less than the maximum intensity of the first control force, especially when the plug is in contact with the base. In addition, the second control force F2 is opposite to the first control force F1. When the plug 10 comes closer to and contacts the base 20, the intensity of the first control force F1 becomes greater than that of the second control force F2. Thus, the first control force F1 acts directly on the magnetic element 23 and causes its displacement. There is then a displacement of the electrical contacts 21, 22 between the first position (disconnected position) and the second position (connected position). Said first control force F1 is thus able to move the electrical contacts 21, 22 between the first position and the second position. If the plug is removed, then the first driving force F1 becomes smaller than the second driving force F2 which is able to move the electrical contacts 21, 22 between the second position and the first position. According to one embodiment of the invention, the set of electrical sockets 1 comprises magnetic or mechanical means of unlocking anticipated the displacement of the two movable electrical contacts 21, 22 moving from the second position 25 (connected position) to the first position ( disconnected position). Said unlocking means are arranged inside the electrical socket assembly to reduce the power ratio between the first control force F1 and the second control force F2 at the time of separation of the plug 10 from the base 20. The magnetic or mechanical means of early unlocking are particularly effective when the movement of the plug is in a direction that is not parallel to the longitudinal axis Y of the assembly. According to a first preferred embodiment of the invention, the set of electrical outlets 1 comprises magnetic means for early unlocking. Said early unlocking magnetic means comprise a first annular repulsion magnet 40 integrated in the base 20 and a second annular repulsion magnet 41 integrated in the plug 10. The repulsion magnets 40, 41 are arranged so as to generate a third control force F3 opposing the first control force F1. The first and second annular repeller magnets 40, 41 are respectively integrated in the base 20 and the plug 10. When the plug 10 is in contact with the base 20, said magnets are arranged so as to be geometrically screwed together. opposite and to be in magnetic opposition. The third control force F3 generated by the annular repulsion magnets 40, 41 is of intensity less than the maximum intensity of the first control force F1. In addition, the annular repelling magnets 40, 41 are of diameter greater than the diameter of the first annular magnet 13. Said magnets are preferably respectively placed on the periphery of the base and the plug. This positioning on the periphery makes it possible to privilege, during an angular aperture, a proximity of the repulsive magnets 40, 41 rather than that of the magnet 13 and the magnetic element 23. Thus, a repulsion phenomenon related to the repulsion magnet 10 41 is made a priority with respect to the attraction phenomenon related to the magnet 13 and the magnetic element 23. The operation of the electrical outlet assembly is as follows when the plug 10 is removed from the base 20. As shown in Fig. 6A, if the plug is removed from the base in a direction substantially parallel to that of the longitudinal axis Y of the tap assembly, the second and third control forces F2, F3 oppose the first force F1 control. The latter being inversely proportional to the distance e separating the plug 10 from the base 20, quickly becomes of intensity less than the second and third control forces F2, F3 which then tend to recall the electrical contacts 21, 22 of the second position ( connected position) to the first position (disconnected position). The distance e substantially corresponds to the largest between a point of the circumference of the plug 10 and the flat surface of the base 20 in the direction Y. The so-called separation distance is small so that a user can not enter in contact with the electrical contacts 21, 22 placed still in the second position (connected position).
If the plug is removed from the pedestal in a direction that is not parallel to that of the longitudinal axis Y of the tap assembly, as shown in Figure 6B, a portion of the plug 10 remains in contact with the pedestal 20 while another part is separated from the base by a separation distance e. However, as shown in FIG. 7, unlike the known solutions (FIG. 5), the evolution curves of the force of attraction of the plug 10 on the base 20 are only dependent on the distance e between said plug and said base. The presence of an angle of tear of the plug relative to the base no longer delays the passage of the electrical contacts from the second position (connected position) to the first position (disconnected position).
A first set of two curves on the upper part of FIG. 7 represents the evolution of the first control force F1. A first curve in full line represents the evolution of said force when the movement of the plug is in a direction parallel to the longitudinal axis Y. A second dashed line represents the evolution of said force when the displacement of the plug is not made in a direction parallel to the longitudinal axis Y. A second set of two curves on the middle part of Figure 7 shows the evolution of the third control force F3. A first curve in full line represents the evolution of said force when the movement of the plug is in a direction parallel to the longitudinal axis Y. A second dashed line represents the evolution of said force when the displacement of the plug does not occur in a direction parallel to the longitudinal axis Y. The resultant force of the first and third control forces F1, F3 vary depending on the tear angle. Likewise, Said resultant force varies as a function of the distance e during tearing in a direction parallel to the longitudinal axis Y. According to this embodiment of the invention, this variation of the resultant force is substantially the same in both types of tearing (angular or linear). According to a second preferred embodiment of the invention, the set of 10 electrical sockets 1 comprises mechanical means for unlocking the movement of the two movable electrical contacts 21, 22 moving from the second position (connected position) to the first position ( disconnected position). The mechanical unlocking means are placed inside the base 20. Said means comprise a slide 50 supporting the electrical contacts 15 21, 22. Said slide is guided in translation relative to the base 20, preferably in a direction substantially coincident with that of the longitudinal axis Y. In a particular embodiment, the slider is slidably mounted on a longitudinal guide 70 integral with the base 20. The slider comprises a guide opening through which the longitudinal guide 70 passes. The mechanical unlocking means comprise in in addition to a hollow cradle 60 supporting the annular magnetic element 23 magnetic control means. According to a particular embodiment, the annular magnetic element is preferably fixed on an edge of the opening of the cradle, the edge having a circular profile. The cradle 60 has a bottom 61 in which a hemispherical bearing surface 51 of the slider 50 is supported. Said cradle is placed in a hollow internal volume of the base 20. As shown in FIGS. 12 to 17, the bottom 61 of the Hollow cradle 60 preferably has a circular collar 62 projecting from said bottom. The hemispherical bearing surface of the slider 50 is then supported on said flange. In addition, the bottom of the hollow cradle comprises a hole for the passage of the translation guide 70 of the slide 50. The flange 62 is then disposed on the perimeter of the hole 63 placed at the bottom of the cradle 60. The cradle comprises an outer surface arranged to to the internal volume of the base 20 so as to be able to move in translation and / or pivot vis-à-vis the base 20. The displacement of the cradle allows to drive in translation the slide 50 and the electrical contacts 21 , 22 between the first and the second operating position. According to this embodiment, the elastic control means 28 preferably comprises at least two return springs arranged symmetrically with respect to the longitudinal axis Y passing through the center of the annular magnetic element 23 of the magnetic control means. The springs respectively exert tensile forces on the cradle 60 tending to place the electrical contacts 21, 22 in the first operating position (disconnected position).
As shown in FIG. 11A, the second control force F2 which is equal to the resultant force of the forces F2a, F2b generated respectively by the return springs 28 is of intensity less than the maximum intensity of the first control force F1. . In addition, the second control force F2 has a direction opposite to the first control force F1. According to this embodiment, the return springs are identical. Thus, the restoring forces F2a, F2b exerted by said springs are equal on the one hand when the plug 10 is in contact with the base 20 or on the other hand when the plug 10 is away from the base 20 so that the first control force F1 does not apply between the base 20 and the plug 10.
When tearing the plug 10 in a direction not parallel to the longitudinal axis Y, the operation of the set of electrical outlets is as follows: As shown in Figure 11 B, part of the plug 10 remains in contact with the base 20 at the point P while another part is separated from the base by a separation distance e. As shown in FIG. 11B, this geometrical imbalance of the plug with respect to the longitudinal axis Y also causes a change of orientation of the first control force F1 that is no longer aligned with said axis. The first magnet 13 and the magnetic element 23 are no longer vis-à-vis over their entire surface. In this configuration, the first control force F1 is expressed in the form of a pair C1 at the point P. The second control force F2 remains unchanged but is expressed in the form of a pair C2 of direction opposite to Cl at the point P. The dotted line curve on the upper part of Figure 10 shows the evolution of the torque Cl during an angular tearing. Cl torque decreases with increasing separation distance e. The C2 pair remains constant. When this distance reaches a value e_dec_ang the torque Cl is no longer sufficient to compensate for the action of the pair C2. As shown in FIG. 13, this imbalance of the torques causes pivoting of the cradle 60 inside the base 20. As shown in FIG. 11C, the forces F2a and F2b of the return springs 28 change at the same time and intensity, which has the effect of maintaining the cradle 60 in this rotated position. This pivoting of the cradle concomitantly causes a displacement of the hemispherical contact surface 51 of the slider 50 on the bottom 61 of said cradle and a displacement of said slider in translation. The curve in solid lines on the lower part of FIG. 10 represents when it changes the first control force F1 during tearing along the longitudinal axis. The transition from the second position (connected position) to the first position (disconnected position) takes place for a distance e_dec_lin. The positioning of the return springs 28 makes the distance e_dec_ang significantly less than e_dec_lin. Thus, the displacement of the electrical contacts 21, 22 from the second position (connected position) to the first position (disconnected position) is not delayed by the fact that the plug 10 is torn off in a direction which is not parallel to the longitudinal axis Y. According to this second embodiment, the base 20 comprises pressure means 80 generating a pressing force maintaining a mechanical contact between the hemispherical bearing surface of the slider 50 and the bottom of the cradle.
According to an alternative embodiment of the development modes of the invention as shown in Figures 17 and 18, the base 20 of the electrical outlet assembly 1 comprises shutter means 26. Said shutter means are positioned in front of the openings 27 to through which electrical contacts can pass. In addition, 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. According to this embodiment, the opening of the shutter means 26 is preferably caused by a thrust of the electrical contacts 21, 22 on said shutter means 26. When the electrical contacts 21, 22 move from the first to the second position under the action of the first control force, they tend to spread the shutter means 26 to pass through the openings 27. Advantageously, the shutter means 26 are brought into a closed position under the action of force generated by closing springs 29. In addition, the shutter means 26 of each opening respectively comprises two shutter flaps. Each shutter shutter is then connected to a closing spring 29. According to another variant embodiment, the base 20 comprises contact pressure springs 30. In practice, each electrical contact is integrally connected to the magnetic element 23 by a contact pressure spring 30. Said springs make it possible to ensure that the contact pressure between each electrical contact 21, 22 and an electrical track 11, 12 is sufficient for the passage of electric current between the base 20 and the plug 10.
