Definitions
- the present invention generally relates to the field of power sockets.
- a socket of the aforementioned type in which the means for raising the piston comprise two springs which bear, on the one hand, on the piston, and, on the other hand, on the bottom of the base.
- the means for raising the piston comprise two springs which are housed in chimneys extending to the bottom of the base of the power socket.
- a socket with a movable piston in which the means for raising the piston are formed by friction elements arranged on the piston so as to be in contact with the pins of the electrical plug inserted into the socket. These friction elements make it possible, by friction, to raise the piston to the high position when removing the pins from the electrical plug, but these means of raising the piston are not very effective.
- the present invention proposes a power socket in which the space available at the bottom of the base is freed up in order, on the one hand, to be able to arrange the cells for receiving the connection terminals along an axis oriented at 45° relative to the usual horizontal axis, and, on the other hand, allowing the electrical connection of the connection terminals from two opposite lateral sides of the base.
- a power outlet as defined in claim 1 is proposed.
- the means for raising the piston in the high position are located in the front space of the power socket, so that the rear space of the base is cleared for, on the one hand, arranging the reception cells of the terminals of connection along an axis oriented at 45° with respect to the usual horizontal axis, and, on the other hand, having transverse contact blades making it possible to supply each connection terminal on one side or the other of the base.
- front and rear will be used with respect to the direction of the user's gaze turned towards the power outlet mounted in the wall or trunking.
- front of an element will designate the side of this element that faces the user, and the back will designate the opposite side.
- This socket 1 comprises an insertion well 2 adapted to receive an electrical plug for the electrical connection of this electrical plug to an electrical network.
- the socket 1 is intended to be mounted in an apparatus support (not shown) itself intended to be positioned either in an electrical box fitted or attached projecting on any wall, or in a trunking.
- this power outlet could be an extension-type outlet, or form part of a power strip, without the principle of the invention being modified.
- the socket 1 comprises an insulating base 10, housing the electrical components of said socket, and a trim 20 which materializes, inside the base 10, the insertion well 2 of the socket 1.
- the base 10 is made of insulating material, for example by molding a plastic material. It has a generally parallelepipedic shape (see figure 1 , 4 , 5 And 19 ). It comprises a bottom wall 11, from which rises, generally perpendicularly, a side wall 12 having four sides, two by two opposite. The base thus forms a box, open at the front (see figures 3 to 5 ).
- the base 10 accommodates a cover 30; 90, made of insulating material, located at the border between a front part 10A and a rear part 10B of the base 10.
- the cover 30; 90 thus forms an intermediate bottom of the base 10 (see figure 2 , 3 And 19 ).
- the cover 30; 90 is formed by a generally rectangular plate whose front face is generally flat and extends substantially parallel to the bottom wall 11 of the base 10 (see figure 5 And 19 ).
- the cover 30 comprises fixing means intended to cooperate with complementary fixing means of the base. More specifically, to prevent any forward movement of the cover 30, said cover 30 carries, on the one hand, projecting from two opposite lateral sides, anti-tearing teeth 31 A folded in a U (see figure 5 ), and, on the other hand, projecting from the other two opposite lateral sides, simple hooking teeth 31B (see figure 5 ), said anti-tearing teeth 31A and simple hooking teeth 31B each having a gripping surface intended to cooperate with restraint with the complementary gripping surface of a window 13 provided in the side wall 12 of the base 10 (see figure 4 And 5 ).
- the cover carries fins 33 projecting from two of its opposite lateral sides (see figure 5 ), and intended to rest on protrusions (not visible) provided projecting from the inner face of two opposite sides of the side wall 12 of the base 10.
- said cover 30 also comprises studs 34 extending rearward (see figure 5 ) and intended to rest against elements housed in a rear space 1B of the base 10 of the socket 1 (see picture 3 ).
- Said rear space 1B of the base 10 delimited by the rear part 10B of the base 10, houses the electrical contact elements of the socket 1 (see figure 2 ).
- This rear space 1B is more precisely closed at the rear by the bottom wall 11 of the base 10, at the front by the cover 30, and laterally by a part of the side wall 12 of the base 10 (see figure 2 And 3 ).
- Three connection terminals 40 are mounted in this rear space 1B of the base 10: a phase terminal, a neutral terminal, and an earth terminal (see picture 2 ).
- each of these connection terminals 40 is an automatic terminal provided with two end conductive cages 41, respectively accessible from two opposite lateral sides 12A, 12B of the base 10, via a pair of respective openings 15 (visible in figure 1 And 5 ), and electrically connected to each other by a transverse contact blade 42 carrying a reception socket 43 intended to receive a pin of the electrical plug (phase and neutral terminal), or an earth pin 44 (earth terminal) intended to ground the electrical plug.
- a transverse contact blade 42 carrying a reception socket 43 intended to receive a pin of the electrical plug (phase and neutral terminal), or an earth pin 44 (earth terminal) intended to ground the electrical plug.
- One of the openings of each pair of openings 15 is intended for the passage of the stripped core of an electric wire coming from the network carrying the neutral, phase, or grounded current, into the conductive cage 41, the another opening being provided for a possible transplanting of this connection terminal 40.
- the spring blade of each conductive cage is actuated by a pull tab or a pusher 46 figure 5 ) allowing
- the reception cells 43 connected to the contact blades 42 of the neutral and phase terminals are located opposite two passage openings 35 provided in the cover 30, through which the connection pins of the electrical plug can be introduced into said receiving cells 43 (see figures 2 to 5 ).
- the reception cells 43 of the connection terminals 40 of the power socket 1 are here aligned along an axis X oriented at 45° relative to the usual horizontal axis H which is the axis generally parallel to the floor of the room in the which socket 1 is mounted (see figure 4 ).
- the insulating base 10 being usually mounted in a receiving wall of a room with one of its side walls 12 parallel to the ground, the axis X of alignment of the receiving cells 43 of the terminals of connection 40 of the socket 1 is oriented at 45° from each side wall 12 of said base 10.
- the ground pin 44 here cylindrical in shape, is powered by the contact blade 42 via a conductive foot 46 which carries said pin ground 44 at a distance from the bottom wall 11 of the base 10 (see figure 5 ).
- the ground pin 44 extends through the cover 30, via another passage opening 36, inside the front part 10A of the base 10 (see figure 4 ).
- the front part 10A of the base 10 is intended, on the one hand, for mounting the socket 1 in the device support, and, on the other hand, to receive the trim 20 of the socket 1.
- the front part 10A of the base 10 of the power outlet 1 comprises, on the one hand, a curb 14 projecting outwards, close to its front edge, the rear face of which is intended to bear against a front face of the device support, and, on the other hand, snap-fastening means 16, provided in the side wall 12 of the base 10, intended to s hang on the back of the support (see figures 1 and 2 ).
- the trim 20 is attached to the front part 10A of the base 10 so as to close said base 10 from the front.
- the trim 20 comprises for this purpose hooking means, here in the form of lugs 25 terminated by a hooking tooth 25A (see figure 13 ), intended to be hooked into complementary hooking means of the front part 10A of the base 10, here windows 17 provided in the side wall 12 of the base 10 (see figure 1 And 4 ).
- a front part 21 of the trim 20 is intended to bear against the front face of the sidewalk 14 of the front part 10A of the base 10 of the socket 1 (see figure 2 ).
- the trim 20 comprises a cylindrical wall 22, which laterally delimits the insertion well 2 of the socket 1, the front part 21 which borders laterally, at the front, this cylindrical wall 22, and a piston 50 movably mounted inside the insertion well 2.
- the insertion well 2 of the power socket 1 is the space into which the socket of the electrical plug is inserted.
- the piston 50 is movably mounted inside the cylindrical wall 22 of the trim 20 so as to close off the section of the insertion well 2 that it delimits.
- This piston 50 forms a mobile bottom of the insertion well 2.
- the piston 50 is movable in translation with respect to said cylindrical wall 22, along the longitudinal central axis of extension of this cylindrical wall 22, here called for convenience axis of revolution R of the cylindrical wall 22 (see picture 3 ), between two extreme positions: a high standby position, and a low position for activating the current outlet.
- the high position represented on the figure 1 , 3 , 7 And 19 , corresponds to the rest position of the trim 20, in which the front face 50A of the piston 50 is aesthetically flush with the front face 21A of the front part 21 of the trim 20.
- the low position (not shown) corresponds to the position in which the piston 50 extends at the bottom of the insertion well 2, against the cover 30 forming the intermediate bottom of the base 10.
- the piston 50 comprises, at the front, a piston wall 55 whose front face forms the front face 50A of the piston 50 (see figure 3 And 6 ).
- This piston wall 55 comprises a disc 54 in which there are three passage orifices 53, and a cylindrical wall 56 laterally bordering said disc 54 towards the rear (see figure 3 And 6 ).
- Two of the passage orifices 53 of the disc 54 of the piston wall 55 are provided opposite the passage openings 35 of the cover 30 (see picture 3 ) and aligned along the same X axis oriented at 45° as the reception cavities 43 of the phase and neutral terminals (see figure 1 ).
- the third passage orifice 53 of the disc 54 of the piston wall 55 is opposite the earth pin of the current socket 1 (see picture 3 ).
- the piston 50 Under normal conditions of use, the piston 50 is adapted to be pushed back, from its high position to its low position, by inserting the pins of the electrical plug into the passage holes 53 of the piston wall 55, which makes it possible to bring the base of the electric plug into contact against the disc 54 of the piston wall 55 and to exert a thrust force there.
- the passage orifices 53 of the piston wall 55 In the low activation position, the passage orifices 53 of the piston wall 55 extend close to the passage openings 35 of the cover 30 so that the pins of the electrical plug can enter the reception cells 43 of the power outlet 1.
- the current outlet 1 also comprises means 60 for raising the piston 50 from its low position to its high position (see figure 2 , 3 And 19 ). These lifting means 60 of the piston permanently exert a force tending to bring the piston 50 back to the high position. Thus, as soon as the pins of the electrical plug are withdrawn from the reception cells 43 of the socket 1, and the base of the electrical plug is removed from the insertion well 2, the piston 50 automatically rises to its high position .
- stop tabs 57 here four in number, extending radially outwards from the rear edge of the cylindrical wall. 56 from piston wall 55 (see figure 6 ), and intended to come into abutment against a surface 23 of the cylindrical wall 22 of the trim 20, perpendicular to the axis of translation of the piston (see picture 3 ).
- the lifting means 60 of the piston 50 are located exclusively in a front space 1A of the power outlet, delimited, on the one hand, laterally by said cylindrical wall 22, and, on the other hand, at the rear, by the cover 30 which closes the rear space 1B of the base 10 (see figure 2 And 3 ).
- the front space 1A in which the lifting means 60 of the piston 50 are located is itself located inside the front part 10A of the base 10 of the power outlet 1 (see picture 3 ).
- the lifting means 60 of the piston 50 thus arranged in the front space 1A leave the rear space 1B of the base 10 entirely available for arranging the connection terminals 40 therein so that, on the one hand, the reception cells 43 are aligned along the X axis, oriented at 45° relative to the usual horizontal axis H, and, on the other hand, the contact blades 42 extend transversely from one side to the other of the base 10 for the connection side of said connection terminals 40.
- the lifting means 60 of the piston 50 present no risk of interference with the connection terminals 40 of the power outlet 1.
- the lifting means 60 of the piston 50 more precisely comprise at least one compression spring 61; 63 which extends along the axis of translation of the piston 50 (see figure 2 , 3 And 19 ).
- This compression spring 61; 63 has a rear end 62; 65 which bears against the front face 30A; 90A of hood 30; 90, and a front end 64; 67 which bears against part of the piston 50 (see figure 3 And 19 ), so that said compression spring 61; 63 is interposed between the cover 30; 90 and the piston 50 to permanently push the piston 50 to its high position.
- the compression spring 61 is unique and extends along the axis of revolution R of said cylindrical wall 22. It has a cross section, in a plane perpendicular to said axis of revolution R, whose diameter is here much smaller than the diameter of the cross section of the cylindrical wall 22.
- a rear portion of the spring is housed in a housing 37 of the cover 30 which holds it in place even when it is compressed (see picture 3 ). More specifically, the cover 30 carries a cylindrical sleeve 38 which extends forwards and laterally delimits the cylindrical housing 37 (see figures 2 to 4 ) receiving the rear portion of the compression spring 61.
- the rear end 62 of the compression spring 61 then bears against a bearing surface 39 formed by the bottom of the housing 37 (see figures 3 and 4 ), so that said compression spring 61 is maintained in the previously defined front space 1A, regardless of the position of the piston 50.
- a front portion of said compression spring 61 is wound around a central rod 58 of the piston wall 55 (see picture 3 ) extending at the rear of the disc 54 of the piston wall 55, perpendicular to this disc 54, along the axis of revolution R of the cylindrical wall 22 of the trim 20 (see figure 6 ).
- the bottom of the housing 37 delimited by the sleeve 38 is pierced with a passage opening 32 provided to allow part of the said central rod 58 to pass (see figures 3 and 4 ).
- a part of the central rod 58 of the piston wall 55 then extends into the rear space 1B of the base 10, the assembly of the compression spring 61 being wound around of the part of the central rod 58 still located in the front space 1A.
- the length of the central rod 58 is such that when the piston 50 is in the low position, it sinks into the central part of the rear space 1B without interfering with the electrical contact elements, its free end remaining at the -above the contact strips 42 which extend against the bottom wall 11 of the base 10 (see picture 3 ).
- the disc 54 also carries, at the rear, two studs 52 in an arc of a circle surrounding the rod and delimiting a housing in which the front portion of the compression spring 61 is maintained (see figure 6 ).
- the compression spring 63 is also unique and extends along the axis of revolution R of said cylindrical wall 22. It has a cross section, in a plane perpendicular to said axis of revolution R, the diameter of which is practically equal, except for clearance, to the internal diameter of said cylindrical wall 22, so that said compression spring 63 is a peripheral spring which runs along the internal face 22A of cylindrical wall 22 .
- the compression spring 63 according to this second embodiment is sufficiently close to the cylindrical wall 22 so as not to risk moving or becoming off-axis when it is compressed.
- This configuration makes it possible to have great stability during the displacement of the piston 50. It is then not necessary to provide special arrangements allowing the compression spring to be guided or held in place when it is compressed.
- the cover 90 of the power socket 1 according to the second embodiment is in all respects identical to the cover 30 according to the first embodiment except that it does not include a central housing intended to hold the spring of compression in position during its compression.
- the piston wall does not include a central rod intended to hold the spring in place during its compression.
- a single central spring, of intermediate section that is to say whose diameter is strictly lower than that of the cross section of the cylindrical wall, without necessarily being much lower than the latter.
- a spring is for example arranged around the openings of the cover allowing the passage of the earth pin or access to the phase and neutral terminals, while being sufficiently far from the cylindrical wall so as not to be able to press against this last and use it as a guide when compressing. It is then necessary to provide on the cover a housing receiving the rear end of this spring, for example a cylindrical groove in which the rear end of the spring is housed, to prevent any movement of the spring during its compression. A similar groove could be provided on the rear face of the piston wall to hold the forward end of the spring in place as it is compressed.
- the means for raising the piston comprise two compression springs which extend on either side of the axis of revolution of the cylindrical wall, and whose respective rear ends are housed in two housings of the cover.
- This third embodiment is very similar to the first embodiment, except that instead of a single central compression spring, two compression springs are provided, arranged symmetrically with respect to the axis of revolution of the cylindrical wall, so that said piston is not unbalanced during its movement towards its low position.
- a shutter 71 housed in the piston 50 and intended to close the passage orifices 53 of the piston wall 55 , and, on the other hand, locking means 82, 84 of the piston 50 in the high position (see figure 2 And 3 ).
- the piston 50 comprises in particular a cassette 70 housing the obturator 71, attached to the rear of the disc 54 of the wall of the piston 55 so as to be integral in translation with the said wall of the piston 55 (see figure 6 ).
- This cassette 70 is in the form of a box open at the front, comprising a bottom wall 77 from which rises a side wall 79, bordered at the front, by a curb 79A of circular outline ( see figure 6 ).
- the lateral edge of the sidewalk 79A of the cassette 70 comprises four protuberances 72A projecting outwards and intended to cooperate in force with the internal face of the cylindrical wall 56 of the piston wall 55 (see figure 6 ).
- Four tabs 72B extend rearward from the lateral edge of said sidewalk 79A and are intended to rest on complementary protrusions 59 provided on the internal face of cylindrical wall 56 of piston wall 55 to prevent separation towards the rear of cassette 70 and piston wall 55 (see figure 6 ).
- the bottom wall 77 of the cassette 70 is pierced with two circular openings 73B (see figure 6 ) arranged opposite, on the one hand, passage openings 35 of cover 30, and, on the other hand, passage orifices 53 of disc 54 of the piston wall 55 (see picture 3 ).
- two keying walls 51 in the shape of a semicircle extending to the rear of the disc 54 of the piston wall 55 and intended to cooperate with semicircular openings 73A of cassette 70 (see figure 6 ).
- the bottom wall 77 of the cassette 70 is also pierced with a central opening 73C allowing the passage of the means for raising the piston 60, in particular the central rod 58 of the disc 54 and the compression spring 61 (see picture 3 ).
- the shutter 71 is movably mounted in the cassette 70, between a closed position (see figure 3 And 7 ) in which it prohibits access to the phase and neutral terminals, by interposing itself between the passage orifices 53 of the disc 54 of the piston wall 55 and the circular openings 73B of the cassette 70 which communicate with the openings of passage 35 of cover 30, and an open position (not shown) in which it allows this access.
- the shutter 71 thus protects the user from possible electrical contact with the conductive elements housed in the rear part 10B of the base 10 of the socket 1.
- the shutter 71 is presented here in the form of a helix (see figure 3 And 6 ) pivotally mounted in the cassette 70 of the piston 50, the blades of which each comprise, on the front face, an inclined face of inverted slope.
- the shutter 71 has a return means, here in the form of a leaf spring 74 (see figure 6 ), intended to automatically return the shutter 71 to the closed position.
- This leaf spring 74 permanently exerts a thrust force tending to push the shutter 71 into the closed position against two abutment studs 75 extending to the rear of the disc 54 of the piston wall 55.
- the locking means 82, 84 of the piston 50 in the high position intervene between the piston 50 and the cylindrical wall 22 of the trim 20 (see picture 3 , 11 and 15 ). They are therefore located in the front part 10A of the base 10 of the socket 1.
- Said locking means 82, 84 of the piston 50 in position high comprise, on the one hand, at least two lugs 82 belonging to said piston 50, and, on the other hand, at least two notches 84 formed in the internal face of the cylindrical wall 22, intended to accommodate said lugs 82.
- the piston 50 comprises in particular a locking wheel 80, attached to the rear of the cassette 70 of the piston 50 and carrying four lugs 82 of generally parallelepiped shape, which extend radially towards the outside of the locking wheel 80 in being two by two diametrically opposed (see figure 6 ).
- notches 84 made in the inner face of the cylindrical wall 22 (see figures 11 to 13 ). These notches 84, of complementary shape to the section of the tabs 82 of the locking wheel, that is to say here of rectangular shape, extend globally orthogonally to the direction of translation of the piston (see figures 11 and 15 ). Each notch 84 of the cylindrical wall forms a retaining surface 83 perpendicular to the direction of translation of the piston, against which rests the lug 82 of the locking wheel 80 engaged in said notch 84 to block the translation of the piston 50 from its high position to its low position (see figure 15 ).
- the locking wheel 80 is adapted to pivot around the axis of revolution R of the cylindrical wall 22 of the trim 20 (see picture 3 ), between a blocking position in which each lug 82 is engaged in a notch 84 and bears against the retaining surface 83 of this notch 84 (see figure 15 ), and an unlocking position in which each tab 82 is released from said retaining surface 83 of the notch 84 to allow the translation of the piston 50 between its high and low positions (see figure 18 ).
- the locking wheel 80 is mounted on the cassette 70 so as to be integral in translation with said cassette 70, while being free to pivot with respect to said cassette 70 which is, for its part, mounted fixed in pivoting on the piston wall 55.
- the cassette 70 carries for this purpose, at the rear of its sidewalk 79A, two hooking lugs 76 (see figure 6 ) extending diametrically back-to-back, perpendicular to said pavement 79A of the cassette 70, each terminated by a hooking tooth 76A intended to snap into place at the rear of a retaining surface 86 of the wheel of blocking 80 (see figure 3 And 6 ).
- Each gripping tooth 76A is short enough relative to the length of the retaining surface 86 to be able to move along this retaining surface 86 and allow locking wheel 80 to pivot.
- bottom 77 of the cassette 70 bordering on either side the central opening 73C of the cassette, and intended to cooperate with notches 81B in the corresponding arc of a circle of the locking wheel 80 (see figure 6 ).
- Each notch 84 of the cylindrical wall 22 of the cover 20 communicates with a guide groove 26 formed in the said cylindrical wall 22, extending along the axis of translation of the piston (see figures 11 to 14 ).
- Each guide groove 26 is intended to receive one of the lugs 82 of the locking wheel 80 when the latter reaches its unlocking position (see figures 14 and 18 ). The cooperation of each leg 82 of the locking wheel 80 with the corresponding guide groove 26 guides the piston 50 in translation between its high and low positions.
- the locking wheel 80 is driven in pivoting by the pivoting of the shutter 71 from its closed position to its open position, following the insertion of the pins of plug into the passage holes 53 of the piston wall 55.
- the shutter 71 comprises for this purpose (see figure 6 ) drive means 78 adapted, during its movement from its closed position to its open position, to rotate the locking wheel 80 from its locking position to its unlocking position.
- the shutter 71 here carries two drive lugs 78 extending parallel to the direction of translation of the piston, facing each other, on either side of the central rod 58 of the disc 54 of the piston wall 55, between the studs 52 in an arc of a circle carried by said disc 54 (see figure 6 ).
- said locking means 82, 84 of the piston 50 in the high position are also automatically disengageable in the event of impact. intervening on a front face 50A of the piston 50, and are combined with energy dissipation means 27, dissipating the energy acquired by the piston 50 during this shock in order to limit the recoil of the piston 50 in said well of insert 2 after this shock.
- the socket 1 remains intact and is not damaged when it receives a shock on the front face 50A of its piston 50.
- the dimension of the retaining surface 83 of the notch 84 provided in the cylindrical wall 22 of the trim 20 is such that the lug 82 of the locking wheel 80 disengages from said notch 84 when the impact occurring on the front face 50A of the piston 50 is of the IK7 type (see figure 15 ).
- An IK7 type shock is defined by the "NF EN 62262" standard and corresponds to an impact force associated with the fall of a mass of 0.5 kg from a height of 400 mm, i.e. an energy transmitted to the piston of about 2 Joules.
- the dimension of the retaining surface 83 of the notch 84 considered is the length L1 of the retaining surface 83 along a direction tangent to said cylindrical wall 22, in a cross section of said insertion well 2 (see figure 15 ).
- Each leg 82 of the locking wheel 80 further comprises a rounded corner 85 (see figures 15 to 18 ).
- This rounded angle 85 is intended to slide against said retaining surface 83 of notch 84 to facilitate the disengagement of said lug 82 from notch 84, when the shock occurring on the front face 50A of piston 50 is of the IK7 type.
- each leg 82 of the locking wheel 80 of the piston 50 is made of rigid plastic material, non-deformable by an IK7 type shock occurring on the front face 50A of the piston 50.
- the leg 82 is automatically disengaged, it that is to say that it comes out of the notch 84 for an impact of the IK7 type, without breaking.
- each notch 84 and the corresponding guide groove 26 is achieved via a ramp 27, that is to say an inclined surface, forming a contact surface against which the tab 82 of the locking wheel 80 slides to be braked before it engages in said guide groove 26.
- the contact surface formed by the ramp 27 is for example chosen to be concave in shape, facing the front of the power outlet 1 (see figure 15 ). This shape allows the piston 50 to be slowed further before the lugs 82 of the locking wheel 80 engage in the guide grooves 26.
- the length of the contact surface formed by the ramp 27 is such that, for an IK7 type shock, the speed of movement of the piston 50 in the guide groove 26 is strictly lower than a threshold speed at which the piston 50 deteriorates the power outlet 1.
- the junction between the notch 84 and the ramp 27 is smooth, without stops or breaks.
- the meeting line between the notch 84 and the ramp 27 is rounded and not angular. This configuration facilitates the automatic disengagement of the locking means, the rounded leg 82 of the locking wheel 80 sliding more easily out of the notch 84 of the cylindrical wall 22.
- the shutter 71 remains in the closed position.
- the pivoting of the locking wheel 80 from its locking position to its unlocking position, driven by the shock received on the front face 50A, does not cause the pivoting of the shutter 71 from its closed position to its open position.
- the return means 89 of the locking wheel 80 in the locking position is here formed by a compression spring 89 interposed between a bearing surface 89A of the cassette 70 and a bearing surface 89B of the locking wheel 80 ( see figure 6 ).
- this compression spring 89 is housed in a housing delimited, at the front, by the sidewalk 79A of the cassette 70, at the rear, by the locking wheel 80, and, laterally, on the one hand, by a low wall 87 extending behind the sidewalk 79A of the cassette 70 and whose curved end forms the support surface 89A of the cassette, and on the other hand, by the cylindrical wall 56 of the wall of piston 55, and the bearing surface 89B of the locking wheel 80.
- the ramp putting the notch and the guide groove in communication with each other would have a flat surface instead of a concave one.
- the surface of this ramp would then be coated with a non-slip coating to brake the piston before it arrives in the guide groove.
- the shutter could be mounted in the cassette which can move in translation along an axis orthogonal both to the axis of translation of the piston and to the axis oriented at 45° along which the reception cells are aligned.
- a mechanical system making it possible to transform a translational movement into a rotational movement would then be used between the shutter and the blocking wheel so that the movement of the shutter from its closed position to its open position causes, under conditions normal use, unlocking the locking wheel.

Description
La présente invention concerne de manière générale le domaine des prises de courant.The present invention generally relates to the field of power sockets.
Elle concerne plus particulièrement une prise de courant telle que définie dans le préambule de la revendication 1.It relates more particularly to a power outlet as defined in the preamble of
On connaît déjà, notamment du document
L'encombrement de ces ressorts dans le fond du socle impose une disposition particulière des bornes de connexion dans le socle et empêche un autre arrangement de ces bornes de connexion.The size of these springs in the bottom of the base imposes a particular arrangement of the connection terminals in the base and prevents another arrangement of these connection terminals.
On connaît par ailleurs du document
Afin de remédier à l'inconvénient précité de l'état de la technique, la présente invention propose une prise de courant dans laquelle l'espace disponible au fond du socle est dégagé pour, d'une part, pouvoir disposer les alvéoles de réception des bornes de connexion selon un axe orienté à 45° par rapport à l'axe horizontal usuel, et, d'autre part, autoriser le raccordement électrique des bornes de connexion depuis deux côtés opposés latéraux du socle.In order to remedy the aforementioned drawback of the state of the art, the present invention proposes a power socket in which the space available at the bottom of the base is freed up in order, on the one hand, to be able to arrange the cells for receiving the connection terminals along an axis oriented at 45° relative to the usual horizontal axis, and, on the other hand, allowing the electrical connection of the connection terminals from two opposite lateral sides of the base.
Plus particulièrement, on propose selon l'invention, une prise de courant telle que définie dans la revendication 1.More particularly, according to the invention, a power outlet as defined in
Ainsi, les moyens de remontée du piston en position haute sont situés dans l'espace avant de la prise de courant, de sorte que l'espace arrière du socle est dégagé pour, d'une part, disposer les alvéoles de réception des bornes de connexion selon un axe orienté à 45° par rapport à l'axe horizontal usuel, et,
d'autre part, disposer des lames de contact transversales permettant d'alimenter chaque borne de connexion d'un côté ou de l'autre du socle.Thus, the means for raising the piston in the high position are located in the front space of the power socket, so that the rear space of the base is cleared for, on the one hand, arranging the reception cells of the terminals of connection along an axis oriented at 45° with respect to the usual horizontal axis, and,
on the other hand, having transverse contact blades making it possible to supply each connection terminal on one side or the other of the base.
D'autres caractéristiques non limitatives et avantageuses de la prise de courant conforme à l'invention, prises individuellement ou selon toutes les combinaisons techniquement possibles, sont définies dans les revendications 2 et suivantes.Other non-limiting and advantageous characteristics of the power socket according to the invention, taken individually or according to all the technically possible combinations, are defined in

Par convention, les termes « avant » et « arrière » seront utilisés par rapport à la direction du regard de l'utilisateur tourné vers la prise de courant montée dans la paroi ou la goulotte. Ainsi, l'avant d'un élément désignera le côté de cet élément qui est tourné vers l'utilisateur, et l'arrière désignera le côté opposé.By convention, the terms "front" and "rear" will be used with respect to the direction of the user's gaze turned towards the power outlet mounted in the wall or trunking. Thus, the front of an element will designate the side of this element that faces the user, and the back will designate the opposite side.

La prise de courant 1 est destinée à être montée dans un support d'appareillage (non représenté) lui-même destiné à être positionné soit dans une boîte électrique encastrée ou rapportée en saillie sur une paroi quelconque, soit dans une goulotte. En variante, cette prise de courant pourrait être une prise de type rallonge, ou faire partie d'un bloc multiprises, sans que le principe de l'invention ne soit modifié.The

Le capot 30 ; 90 est formé par une plaquette globalement rectangulaire dont la face avant est globalement plane et s'étend sensiblement parallèlement à la paroi de fond 11 du socle 10 (voir
Dans la suite de la description, l'invention sera décrite plus précisément en référence au premier mode de réalisation de la prise de courant 1 représenté sur les
Le capot 30 comporte des moyens de fixation destinés à coopérer avec des moyens de fixation complémentaires du socle. Plus précisément, pour empêcher tout déplacement vers l'avant du capot 30, ledit capot 30 porte, d'une part, en saillie de deux côtés latéraux opposés, des dents anti-arrachement 31 A repliées en U (voir
Ledit espace arrière 1B du socle 10, délimité par la partie arrière 10B du socle 10, loge les éléments de contact électrique de la prise de courant 1 (voir

Les alvéoles de réception 43 reliés aux lames de contact 42 des bornes de neutre et de phase sont situés en regard de deux ouvertures de passage 35 prévues dans le capot 30, à travers lesquelles les broches de connexion de la fiche électrique peuvent être introduites jusque dans lesdits alvéoles de réception 43 (voir
La partie avant 10A du socle 10 est destinée, d'une part, au montage de la prise de courant 1 dans le support d'appareillage, et, d'autre part, à recevoir l'enjoliveur 20 de la prise de courant 1.The

L'enjoliveur 20 est rapporté sur la partie avant 10A du socle 10 de manière à fermer ledit socle 10 par l'avant. L'enjoliveur 20 comporte à cet effet des moyens d'accrochage, ici sous forme de pattes 25 terminées par une dent d'accrochage 25A (voir
Comme le montrent les
La partie de façade 21, qui présente ici un contour rectangulaire, participe à la finition décorative de la prise de courant 1. Elle est monobloc avec la paroi cylindrique 22. Le puits d'insertion 2 de la prise de courant 1 est l'espace dans lequel le socle de la fiche électrique est inséré.The
Comme le montrent les
Le piston 50 est mobile en translation par rapport à ladite paroi cylindrique 22, le long de l'axe central longitudinal d'extension de cette paroi cylindrique 22, ici appelé pour plus de commodité axe de révolution R de la paroi cylindrique 22 (voir
Le piston 50 comporte, à l'avant, une paroi de piston 55 dont la face avant forme la face avant 50A du piston 50 (voir
En conditions normales d'utilisation, le piston 50 est adapté à être repoussé vers l'arrière, de sa position haute vers sa position basse, par l'insertion des broches de la fiche électrique dans les orifices de passage 53 de la paroi de piston 55, qui permet de mettre en contact le socle de la fiche électrique contre le disque 54 de la paroi de piston 55 et d'y exercer une force de poussée. En position basse d'activation, les orifices de passage 53 de la paroi de piston 55 s'étendent à proximité des ouvertures de passage 35 du capot 30 de sorte que les broches de la fiche électrique peuvent pénétrer dans les alvéoles de réception 43 de la prise de courant 1.Under normal conditions of use, the
La prise de courant 1 comporte par ailleurs des moyens de remontée 60 du piston 50 depuis sa position basse vers sa position haute (voir
Le déplacement du piston 50 vers l'avant, au-delà de sa position haute, est empêché par des pattes de butée 57, ici au nombre de quatre, s'étendant radialement vers l'extérieur à partir du bord arrière de la paroi cylindrique 56 de la paroi de piston 55 (voir
Avantageusement, les moyens de remontée 60 du piston 50 sont situés exclusivement dans un espace avant 1A de la prise de courant, délimité, d'une part, latéralement par ladite paroi cylindrique 22, et, d'autre part, à l'arrière, par le capot 30 qui ferme l'espace arrière 1B du socle 10 (voir
L'espace avant 1A dans lequel sont situés les moyens de remontée 60 du piston 50 est lui-même situé à l'intérieur de la partie avant 10A du socle 10 de la prise de courant 1 (voir
Les moyens de remontée 60 du piston 50 ainsi disposés dans l'espace avant 1A laissent entièrement disponible l'espace arrière 1B du socle 10 pour y disposer les bornes de connexion 40 de manière que, d'une part, les alvéoles de réception 43 sont alignés selon l'axe X, orienté à 45° par rapport l'axe horizontal usuel H, et, d'autre part, les lames de contact 42 s'étendent transversalement d'un côté à l'autre du socle 10 pour la connexion latérale desdites bornes de connexion 40. En outre, les moyens de remontée 60 du piston 50 ne présentent aucun risque d'interférence avec les bornes de connexion 40 de la prise de courant 1.The lifting means 60 of the
Les moyens de remontée 60 du piston 50 comportent plus précisément au moins un ressort de compression 61 ; 63 qui s'étend selon l'axe de translation du piston 50 (voir
Selon le premier mode de réalisation représenté sur les
Selon ce premier mode de réalisation, pour maintenir le ressort de compression 61 en place et le guider en compression lorsque le piston 50 est poussé vers sa position basse, une portion avant dudit ressort de compression 61 est enroulée autour d'une tige centrale 58 de la paroi de piston 55 (voir
Le fond du logement 37 délimité par le manchon 38 est percé d'une ouverture de passage 32 prévue pour laisser passer une partie de ladite tige centrale 58 (voir
Le disque 54 porte également, à l'arrière, deux plots 52 en arc de cercle entourant la tige et délimitant un logement dans lequel la portion avant du ressort de compression 61 est maintenue (voir
Une extrémité dudit ressort de compression 61 est ainsi maintenue (voir
Selon le deuxième mode de réalisation représenté sur la
Du fait de sa large section, le ressort de compression 63 selon ce deuxième mode de réalisation est suffisamment proche de la paroi cylindrique 22 pour ne pas risquer de se déplacer ou de se désaxer lorsqu'il est comprimé. Cette configuration permet d'avoir une grande stabilité lors du déplacement du piston 50. Il n'est alors pas nécessaire de prévoir des aménagements particuliers permettant de guider ou de maintenir en place le ressort de compression lorsqu'il est comprimé. Notamment, le capot 90 de la prise de courant 1 selon le deuxième mode de réalisation est en tout point identique au capot 30 selon le premier mode de réalisation si ce n'est qu'il ne comporte pas de logement central destiné à maintenir le ressort de compression en position lors de sa compression. Similairement, dans ce deuxième mode de réalisation, la paroi de piston ne comporte pas de tige centrale destinée à maintenir le ressort en place lors de sa compression.Due to its large section, the
Selon un mode de réalisation non représenté, intermédiaire entre le premier de mode de réalisation et le deuxième mode de réalisation précités, il est également envisageable de prévoir un ressort central unique, de section intermédiaire, c'est-à-dire dont le diamètre est strictement inférieur à celui de la section transversale de la paroi cylindrique, sans forcément être très inférieur à ce dernier. Un tel ressort est par exemple disposé autour des ouvertures du capot permettant le passage de la broche de terre ou l'accès aux bornes de phase et de neutre, tout en étant suffisamment éloigné de la paroi cylindrique pour ne pas pouvoir s'appuyer contre cette dernière et l'utiliser comme un guide lors de la compression. Il est alors nécessaire de prévoir sur le capot un logement recevant l'extrémité arrière de ce ressort, par exemple une gorge cylindrique dans laquelle se loge l'extrémité arrière du ressort, pour empêcher tout déplacement du ressort lors de sa compression. Une gorge similaire pourrait être prévue sur la face arrière de la paroi de piston pour maintenir l'extrémité avant du ressort en place lors de sa compression.According to an embodiment not shown, intermediate between the first embodiment and the second embodiment mentioned above, it is also possible to provide a single central spring, of intermediate section, that is to say whose diameter is strictly lower than that of the cross section of the cylindrical wall, without necessarily being much lower than the latter. Such a spring is for example arranged around the openings of the cover allowing the passage of the earth pin or access to the phase and neutral terminals, while being sufficiently far from the cylindrical wall so as not to be able to press against this last and use it as a guide when compressing. It is then necessary to provide on the cover a housing receiving the rear end of this spring, for example a cylindrical groove in which the rear end of the spring is housed, to prevent any movement of the spring during its compression. A similar groove could be provided on the rear face of the piston wall to hold the forward end of the spring in place as it is compressed.
Selon un autre mode de réalisation de l'invention, non représenté, les moyens de remontée du piston comportent deux ressorts de compression qui s'étendent de part et d'autre de l'axe de révolution de la paroi cylindrique, et dont les extrémités arrière respectives sont logées dans deux logements du capot. Ce troisième mode de réalisation est très semblable au premier mode de réalisation, si ce n'est qu'à la place d'un unique ressort de compression central, il est prévu deux ressorts de compression, disposés symétriquement par rapport à l'axe de révolution de la paroi cylindrique, de manière que ledit piston ne soit pas déséquilibré lors de son déplacement vers sa position basse. Les aménagements permettant de guider les ressorts en compression et d'éviter qu'ils ne soient désaxés sont alors similaires à ceux prévus dans le premier mode de réalisation de la prise de courant (logement sur le capot et tige à l'arrière de la paroi de piston), si ce n'est que ces aménagements sont dédoublés de manière qu'il est prévu de tels aménagements pour chacun des deux ressorts de compression.According to another embodiment of the invention, not shown, the means for raising the piston comprise two compression springs which extend on either side of the axis of revolution of the cylindrical wall, and whose respective rear ends are housed in two housings of the cover. This third embodiment is very similar to the first embodiment, except that instead of a single central compression spring, two compression springs are provided, arranged symmetrically with respect to the axis of revolution of the cylindrical wall, so that said piston is not unbalanced during its movement towards its low position. The arrangements for guiding the springs in compression and preventing them from being misaligned are then similar to those provided for in the first embodiment of the power socket (housing on the cover and rod at the rear of the wall piston), except that these arrangements are split so that such arrangements are provided for each of the two compression springs.
Quel que soit le mode de réalisation envisagé, pour renforcer la sécurité de l'utilisateur, il est prévu, d'une part, un obturateur 71 logé dans le piston 50 et destiné à fermer les orifices de passage 53 de la paroi de piston 55, et, d'autre part, des moyens de blocage 82, 84 du piston 50 en position haute (voir
Le piston 50 comporte en particulier une cassette 70 logeant l'obturateur 71, rapportée à l'arrière du disque 54 de la paroi de piston 55 de manière à être solidaire en translation avec ladite paroi de piston 55 (voir
Cette cassette 70 se présente sous la forme d'un boîtier ouvert à l'avant, comprenant une paroi de fond 77 à partir de laquelle s'élève une paroi latérale 79, bordée à l'avant, par un trottoir 79A de contour circulaire (voir
La paroi de fond 77 de la cassette 70 est percée de deux ouvertures circulaires 73B (voir
La paroi de fond 77 de la cassette 70 est aussi percée d'une ouverture centrale 73C permettant le passage des moyens de remontée 60 du piston, notamment de la tige centrale 58 du disque 54 et du ressort de compression 61 (voir
L'obturateur 71 est monté mobile dans la cassette 70, entre une position de fermeture (voir
L'obturateur 71 se présente ici sous la forme d'une hélice (voir
Les moyens de blocage 82, 84 du piston 50 en position haute interviennent entre le piston 50 et la paroi cylindrique 22 de l'enjoliveur 20 (voir
Le piston 50 comporte en particulier une roue de blocage 80, rapportée à l'arrière de la cassette 70 du piston 50 et portant quatre pattes 82 de forme globalement parallélépipédique, qui s'étendent radialement vers l'extérieur de la roue de blocage 80 en étant deux à deux diamétralement opposées (voir
Il est prévu en correspondance quatre encoches 84, ménagées dans la face interne de la paroi cylindrique 22 (voir
La roue de blocage 80 est adaptée à pivoter autour de l'axe de révolution R de la paroi cylindrique 22 de l'enjoliveur 20 (voir
Pour ce faire, la roue de blocage 80 est montée sur la cassette 70 de manière à être solidaire en translation avec ladite cassette 70, tout en étant libre en pivotement par rapport à ladite cassette 70 qui est, quant à elle, montée fixe en pivotement sur la paroi de piston 55.To do this, the
La cassette 70 porte à cet effet, à l'arrière de son trottoir 79A, deux pattes d'accrochage 76 (voir
Chaque encoche 84 de la paroi cylindrique 22 de l'enjoliveur 20 communique avec une rainure de guidage 26 ménagée dans ladite paroi cylindrique 22, s'étendant selon l'axe de translation du piston (voir
En conditions normales d'utilisation de la prise de courant 1, la roue de blocage 80 est entraînée en pivotement par le pivotement de l'obturateur 71 depuis sa position de fermeture vers sa position d'ouverture, suite à l'insertion des broches de la fiche électrique dans les orifices de passage 53 de la paroi de piston 55. L'obturateur 71 comporte à cet effet (voir
Avantageusement, lesdits moyens de blocage 82, 84 du piston 50 en position haute sont en outre automatiquement débrayables en cas de choc intervenant sur une face avant 50A du piston 50, et se combinent avec des moyens de dissipation de l'énergie 27, dissipant l'énergie acquise par le piston 50 lors de ce choc afin de limiter le recul du piston 50 dans ledit puits d'insertion 2 après ce choc.Advantageously, said locking means 82, 84 of the
Ainsi, la prise de courant 1 reste intacte et n'est pas détériorée lorsqu'elle reçoit un choc sur la face avant 50A de son piston 50.Thus, the
Pour ce faire, la dimension de la surface de retenue 83 de l'encoche 84 prévue dans la paroi cylindrique 22 de l'enjoliveur 20 est telle que la patte 82 de la roue de blocage 80 se désengage de ladite encoche 84 lorsque le choc intervenant sur la face avant 50A du piston 50 est du type IK7 (voir
Un choc de type IK7 est défini par la norme « NF EN 62262 » et correspond à une force d'impact associée à la chute d'une masse de 0,5kg d'une hauteur de 400mm, soit une énergie transmise au piston d'environ de 2 Joules.An IK7 type shock is defined by the "NF EN 62262" standard and corresponds to an impact force associated with the fall of a mass of 0.5 kg from a height of 400 mm, i.e. an energy transmitted to the piston of about 2 Joules.
La dimension de la surface de retenue 83 de l'encoche 84 considérée est la longueur L1 de la surface de retenue 83 selon une direction tangente à ladite paroi cylindrique 22, dans une section transversale dudit puits d'insertion 2 (voir
Chaque patte 82 de la roue de blocage 80 comporte en outre un angle arrondi 85 (voir
Comme le montre la
Par ailleurs, comme le montre la
La coopération de la patte 82 de la roue de blocage 80 contre la rampe 27 dissipe l'énergie acquise par le piston et évite que ce dernier ne parvienne avec une vitesse trop importante dans la rainure de guidage 26. Ainsi, soit le piston est suffisamment freiné pour s'arrêter avant d'atteindre sa position basse, soit il arrive en position basse avec une vitesse suffisamment faible pour ne pas détériorer la prise de courant 1, en particulier le capot 30 et les éléments de contact électrique de la prise de courant 1.The cooperation of the
La surface de contact formée par la rampe 27 est par exemple choisie de forme concave, tournée vers l'avant de la prise de courant 1 (voir
La longueur de la surface de contact formée par la rampe 27 est telle que, pour un choc de type IK7, la vitesse de déplacement du piston 50 dans la rainure de guidage 26 est strictement inférieure à une vitesse seuil à laquelle le piston 50 détériore la prise de courant 1.The length of the contact surface formed by the
Comme le montre la
Ainsi, lorsque le piston 50 est bloqué en position haute par la roue de blocage 80 pivotée en position de blocage (voir
De manière avantageuse, lors de ce déplacement du piston 50 lié au choc reçu en face avant, l'obturateur 71 reste en position de fermeture. Autrement dit, le pivotement de la roue de blocage 80 depuis sa position de blocage vers sa position de déblocage, entraîné par le choc reçu en face avant 50A, n'entraîne pas le pivotement de l'obturateur 71 depuis sa position de fermeture vers sa position d'ouverture.Advantageously, during this displacement of the
Par ailleurs, dès que la vitesse du piston 50 est nulle, le ressort de compression 61 des moyens de remontée 60 du piston 50 le repousse en position haute.Furthermore, as soon as the speed of the
Il est d'ailleurs prévu un moyen de rappel 89 de la roue de blocage 80 en position de blocage, distinct du moyen de rappel 74 de l'obturateur 71 en position de fermeture déjà décrit (voir
Lorsque le piston 50 remonte vers sa position haute, et que les pattes 82 de la roue de blocage 80 rencontrent les rampes 27 de la paroi cylindrique 22 de l'enjoliveur 20, ce ressort de compression 89 repousse la roue de blocage 80 vers sa position de blocage.When the
L'invention n'est pas limitée au mode de réalisation décrit et représenté.The invention is not limited to the embodiment described and represented.
Il serait notamment envisageable que la rampe mettant en communication l'encoche et la rainure de guidage présente une surface plane au lieu de concave. La surface de cette rampe serait alors revêtue d'un revêtement antidérapant pour freiner le piston avant son arrivée dans la rainure de guidage.It would in particular be possible for the ramp putting the notch and the guide groove in communication with each other to have a flat surface instead of a concave one. The surface of this ramp would then be coated with a non-slip coating to brake the piston before it arrives in the guide groove.
Il est aussi envisageable d'omettre totalement la rampe mettant en communication chaque rainure de guidage avec l'encoche correspondante, et de munir les parois de la rainure de guidage d'un revêtement antidérapant de sorte que la patte engagée dans la rainure de guidage frotte contre celle-ci pour freiner le piston lors de sa translation.It is also possible to completely omit the ramp placing each guide groove in communication with the corresponding notch, and to provide the walls of the guide groove with a non-slip coating so that the lug engaged in the guide groove rubs against the latter to brake the piston during its translation.
Il serait aussi envisageable que l'obturateur soit monté dans la cassette mobile en translation selon un axe orthogonal à la fois à l'axe de translation du piston et à l'axe orienté à 45° selon lequel sont alignés les alvéoles de réception. Un système mécanique permettant de transformer un mouvement de translation en un mouvement de rotation serait alors utilisé entre l'obturateur et la roue de blocage pour que le mouvement de l'obturateur de sa position de fermeture vers sa position d'ouverture entraîne, en conditions normales d'utilisation, le déblocage de la roue de blocage.It would also be possible for the shutter to be mounted in the cassette which can move in translation along an axis orthogonal both to the axis of translation of the piston and to the axis oriented at 45° along which the reception cells are aligned. A mechanical system making it possible to transform a translational movement into a rotational movement would then be used between the shutter and the blocking wheel so that the movement of the shutter from its closed position to its open position causes, under conditions normal use, unlocking the locking wheel.
