DESCRIPTION

Accessory for a rotary electrical socket

Technical field of the invention

The technical field of the invention is that of electrical outlet equipment.

The present invention relates to rotary electrical outlet equipment and especially to rotary electrical multi-outlet equipment.

Technological background of the invention

Rotating electrical socket sets are already known, which are removable accessories comprising a support and a rotating active part with respect to the support, the rotating active part comprising a plurality of electrical equipment mechanisms such as a current socket.

It is already known that the rotation between the active part and the support is carried out by means of a rotation mechanism with a notch that allows having several angular positions. Documents EP2515391 A1 and KR100682724B disclose electrical socket accessories according to the preamble of claim 1.

Document FR2897724A already knows electrical outlet equipment, in this case a multi-switchgear block made up of an elongated mobile pocket that rotates along an X axis, which houses electrical switchgear mechanisms, a support, and two mechanisms inside. mutually opposed to each other with respect to the X axis. Each rotation mechanism comprises a fixed cylindrical opening with respect to the support that includes a multitude of notches and teeth on its internal periphery and on the other hand on the mobile pocket, a cylindrical part that comprises in its outer periphery multitude of notches and teeth adapted to cooperate with those of the cylindrical opening. These notches and teeth form a plurality of stable angular positions of the movable pocket with respect to the support and allow rotation by friction between the teeth and the notches. Indeed, the projections pass from one notch to another, clearing a hard point in order to make said pocket pass from one stable angular position to another.

However, it has been shown that the use of this type of rotation mechanisms uses the different notches in a heterogeneous way, which leads to a different torque sensation when the mobile pocket is rotated with respect to the base. In fact, this heterogeneous wear of the notches quickly leads to a different feeling when the movable pocket is rotated with respect to the bracket because a movable pocket notch may be worn and interact once with a notch or with a tooth of the unsupported bracket. worn and again with a notch or unworn bracket tooth. Also, when there are two rotating mechanisms opposite each other about an X axis, the teeth and grooves on each side wear differently, this can produce unpleasant torque for the user and can lead to accelerated wear. .of the mechanisms of rotations

There are also rotation mechanisms that include a mobile part that in turn includes lugs and a fixed part that includes a stop and an elastically mounted metal ball that allows step-by-step rotation in the notches of the mobile part. However, such a mechanism involves regular greasing of the elastically mounted ball in order to prevent it from seizing in the housing that houses the ball, causing blocking sensations for the user. In addition, assembly is more complicated and can lead to additional production costs.

Therefore, there is a need to reduce these different sensations of rotation for the same number of uses of the rotation mechanism.

Summary of the invention

The invention offers a solution to the aforementioned problems, by making it possible to have electrical outlet equipment comprising an elastic rotation mechanism with notches.

One aspect of the invention refers to an electrical outlet accessory comprising:

• a support and an active part rotatable with respect to the support along an axis of rotation,

• a notched rotation mechanism that allows rotation of the support with respect to the active part, comprising:

^or a spring blade comprising at least one notch and a stop to be integral with the support or with the active part,

^or a cylindrical part that includes notches that are complementary to the notch of the spring plate,

• and because the spring sheet deforms elastically by bending, when the active part rotates with respect to the support going from one angular position to another angular position and because in each angular position, the notch of the spring blade is in contact with respectively one of the complementary notches of the cylindrical part. Thanks to the invention, the spring sheet that is deformed wears less quickly than the friction between the notches and is easy to assemble. Thus, the notched rotation mechanism does not have any resiliently mounted balls that require ball greasing. In addition, the stop of the leaf spring, being integral with the support or with the rotating active part, allows to have a simple assembly of the leaf spring that is removable in the support or the active part and therefore allows it to be made of another material than that of the support or that of the active part, thus making it possible to conceive and choose more easily the spring effect of the corrugated as well as its wear. In fact, this makes it possible to avoid choosing a more expensive or unsuitable material for the support or for the active part in order to avoid wear on the leaf spring.

Detailed description

The figures are presented as an indication and in no way limiting the invention. Unless otherwise specified, the same element that appears in the different figures has a single reference.

FIG. 1A schematically shows a schematic view of an electrical socket accessory according to a first example of a first embodiment.

In this example, the electrical socket accessory 1 is a multi-electrical switchgear block, here a multi-socket block, designed to rest on a table or a work surface or even on a floor.

The electrical socket accessory 1 comprises an active part 11 elongated along an X axis, which internally houses a plurality of electrical switchgear mechanisms 12 such as current socket mechanisms or switches. In this example, each plurality of electrical switchgear mechanisms 12 comprises two ground pins 122 and two female power plugs 121 but they can, for example, comprise one ground pin and two female pins or even another type of plug according to the standards of the different countries of sale, such as a USB port.

The electrical outlet accessory 1 comprises at least one support 13a, 13b. In this case, in this example, the electrical socket accessory 1 comprises a first support 13a and a second support 13b to support the electrical socket accessory 1 with the X axis parallel to a support, for example horizontal, on a table or a work plane or even on a floor, but it could only comprise a support 13a, 13b whose axis X is perpendicular to a support, for example, vertical with respect to a table.

The electrical outlet accessory 1 comprises a first and a second notched rotation mechanism 3a, 3b that allow the active part 11 to rotate with respect to the first support 13a and the second support 13b respectively. Figure 1B represents in more detail, in exploded view, the second rotation mechanism with notch 3b of a part of the electrical socket accessory 1 and Figure 1C represents a section of the electrical socket accessory 1 at the height of the first rotation mechanism with notch 3a

The electrical socket accessory 1 may also comprise a single notched rotation mechanism, for example the first notched rotation mechanism 3a. In this case, the second support 13b only comprises a connection free to rotate along the X axis with respect to the active part 11.

The active part 11 can be a pocket that preferably has an overall tube shape. The active part 11 is formed in this example by assembling an upper cylindrical half-shell 110A and a lower cylindrical half-shell 110B. The union between the half-shells can be made by stapling or screwing, in this case by screwing.

The active part 11 also comprises, in this example, a trim 111 that fills an opening in the upper half-shell 110A and that here defines a plurality of wells 111A to receive the electrical switchgear mechanisms 12, in this case current sockets, aligned according to the X axis of the active part 11.

Each reception well 111A includes at its bottom two holes that form the female power supply pins 121 for the passage of the contact pins of an electrical plug, and each reception well 111A here includes two pins that form the ground pins 122 that emerge in the receiving pit 111A perpendicular to its bottom.

Said trim 111 comprises, at one end, a key 111B to actuate a control switch of said multi-apparel unit block. In this case, the actuation key can be pivoted along an axis perpendicular to the axis of rotation X and makes it possible to cut off the electrical supply of all the mechanisms of the electrical switchgear.

The active part 11 comprises a first end 113a and a second end 113b opposite the first end 113a, each mounted in rotation about the X axis on the first support 13a and the second support 13b respectively.

Each support 13a, 13b comprises a support element 130 which in turn comprises a circular housing that surrounds respectively the first and the second end 113a, 113b of the active part 11. The internal periphery of the circular housing of the support element 130 of each support 13a, 13b is complementary with an outer peripheral surface of each of the first and second ends. 113a, 113b, respectively.

In this example, each support 13a, 13b is therefore intended to rest on a support surface (not shown) and the active part 11 is therefore an external pocket arranged with each support element 130 to extend above and close to said surface. medium. Each support 13a, 13b comprises two support feet 131 extending from the support element 130 intended to rest on the support surface. In this case, each support foot 131 comprises an opening to fix the feet to the support surface by means of a fixing element such as a screw or a rivet, as well as a rectangular-shaped opening to receive a flexible plastic clamping collar with anti-return system. ratchet, also called cable clamp, for example, of the type known under the "Colson®" brand or the "Colring®" brand that allows fixing on cylindrical or shaped tubular supports.

In this example, each support element 130 of the first and of the second support 13a, 13b comprises an opening traversed by the first and second ends 113a, 113b respectively of the active part 11.

The first and second ends 113a, 113b, the second end 113b of which is particularly visible in Figure 1B, comprise a shoulder having a solid radial surface that closes the interior of the active part 11. The shoulder comprises an outer periphery for centering and they cooperate in rotation with an internal shoulder of the support element 130. Each solid radial surface of the first and second end 113a, 113b thus closes the corresponding support opening 13a, 13b.

The first and second ends 113a, 113b of the active part 11 have an identical shape except that the first end 113a comprises an axial opening traversed by the X axis, filled by a cable gland 18 traversed by a power supply cable 8 visible in section on the right side. figure 1C that represents a radial section of the electrical outlet accessory 1. The power supply cable 8 comprises at least one external part, not shown, and an internal part to connect the electrical switchgear mechanisms 12 to a network, in this case through of the control switch. The power cable 8 in this case comprises three wires to connect the phase, neutral and ground pins. The cable gland 18 extends axially out of the housing formed by the opening of the first support 13a.

According to another example not shown, the active part 11 comprises a radial opening and a cable gland in the opening traversed by a power cable connected to the electrical switchgear mechanisms 12.

According to another example not shown, the first support 13a comprises an axial opening and a cable gland that fills the opening, traversed by a power cable connected to the electrical switchgear mechanisms 12 that passes through an axial opening in the active part.

In this represented example, the rotation of the active part 11 on the support elements 130 of the supports 13a, 13b allows several turns of rotation. The rotation is in this example limited by the torsion of the cable when the latter is connected to an electrical switchgear mechanism to power the electrical switchgear mechanisms 12. Thus, the first and the second notched rotation mechanism 3a, 3b allow several turns around the axis. of rotation X, of the active part 11 with respect to the first and second supports 13a, 13b before a torsion of the cable that blocks the rotation.

According to another example not shown, the cylindrical part can have an anti-rotation stop, such as that shown in a third example of this first embodiment shown in FIG. 3 explained in detail below. The rotation of the active part 11 in the support elements 130 is thus limited by this anti-rotation stop. The rotation of the active part 11, with respect to the first and second supports 13a, 13b, can be carried out by 360° minus the degree of thickness of the anti-rotation stop, for example 258°. The rotation limit makes it possible to prevent the electric cables from being torn off and disconnected when subjected to torsion stresses during the rotation of the active part with respect to the support part. The electric cable has the advantage of not causing an electric arc or an electric fault at each stepwise rotation of the active part 11 with respect to the first and second supports 13a, 13b. In the case where the cable passes through the active part 11 on a radial side, the anti-rotation stopper can also prevent rotation beyond 180° to prevent twisting of the cable around the active part 11.

In another example not shown, in which the rotation mechanism 3a, 3b allows several turns of rotation of the active part 11, with respect to the first and the second supports 13a, 13b, the apparatus may not have any limitation of rotation by the torsion of the cable 8, comprising a connection system with the electrical contact arm that slides on a connection track, pivoting with the support 13a or the active part 11. The tracks are each connected to pins of the same potential of the switchgear mechanisms 12 or to one of the conductors of the cable 8 and the contact arms are respectively connected each to one of the conductors of the cable 8 or to the pins of the same potential of the electrical switchgear mechanisms 12. The number of arms and tracks correspond to the numbers of different potential, in this case three (ground, neutral and phase). For example, the cable 8 comprises for each of these conductors a connection to a corresponding electrical contact arm of the connection system and a 360° track per contact arm, each located on the active part, insulated and offset from each other. , in which each pin of each electrical switchgear mechanism 12 is connected to one of the corresponding tracks. For example, the cable 8 comprises a phase conductor connected to a phase arm, a neutral conductor connected to a neutral arm and a ground conductor connected to an earth arm, and the active part comprises three concentric circular tracks located by example on a radial end face 113a. The tracks can be on an outer radial face of the end 113a of a solid radial surface that closes the interior of the active part 11 or an inner radial face of the radial surface traversed by the cable gland 18, mounted in rotation with this radial surface. of the active part 11. According to another example, the tracks are mounted on an X-axis track shaft comprising rings forming a slip-ring-like track. For example, the track shaft extends in a support housing 13 comprising a radial surface that closes the track shaft housing. The arms of the contacts can each be a conductive elastic sheet prestressed against the corresponding track. The axis of the track can be integral either with the support 13a or with the active part 11 and the contact arms are respectively integral with the active part 11 or with the support 13a.

Each notched rotation mechanism 3a, 3b that allows the rotation of the corresponding support 13a, 13b with respect to the active part 11, comprises a spring blade 30a, 30b forming a notch 300 and a cylindrical part 31 a, 31 b comprising notches 311 complementary to the notch 300 of the spring blade 30a, 30b.

In this example, the two spring sheets 30a, 30b are identical and the cylindrical parts 31a, 31b are identical. In this case, the supports 13a and 13b are also identical. This allows to simplify the assembly and the manufacturing cost.

Each spring sheet 30a, 30b elastically deforms when the active part 11 rotates with respect to the corresponding support 13a, 13b that corresponds from one angular position to another angular position.

In each angular position, the notch 300 of the spring blade 30a, 30b is in contact with respectively one of the corresponding complementary notches 311 of the corresponding cylindrical part 31a, 31b.

The fact that the spring blade 30a, 30b is deformed makes it possible to have a notch 300 that wears out less quickly than between plastic notches that rub against each other at each rotation solely by friction. In addition, such a leaf spring 30a, 30b is easy to mount compared to a spring-mounted ball system that requires lubrication of the ball. Therefore, the spring sheet 30a, 30b is mounted so that it can be removed (removable) and can therefore be made of another material.

In this example represented o, each spring plate 30a, 30b is metallic and the cylindrical part 31 a, 31 b comprising notches 311 is made of plastic.

In this represented example, each spring blade 30a, 30b comprises a single notch 300, thus making it possible to gradually reduce the different sensations at each angular rotation. In addition, the fact of having a rotation mechanism 3a, 3b on each side of the active part 11 with respect to the supports 13a, 13b, makes it possible to reduce the sensation of a torque between the rotating joints of the active part 11 and of the supports 13a, 13b.

In this embodiment, each spring blade 30a, 30b is integral in rotation with the active part 11 and the corresponding cylindrical part 31a, 31b is integral in rotation with the corresponding support 13a, 13b. The mechanism with notches 3a, 3b comprises a radial projection that forms a balancing lug 1103 (of which the end 113A is visible in figures 1A and 1C) facing the notches of the cylindrical part 31a, 31b and is diametrically opposite in the notch 300 of the spring blade 3a, 3b. In this case, each notched mechanism 3a, 3b comprises a balancing pin. Each balancing lug 1103 extends radially towards the cylindrical part which has a maximum radius less than the radius of the notch 300 of the spring blade 3a, 3b. In this case, the maximum radius with respect to the X axis is closer to the smallest radius of each tooth 312 than to the largest radius of each notch 311 of the active part to prevent it from being damaged quickly and changing the feeling of rotation between the teeth. two rotation mechanisms 3a, 3b for the user over time. These balancing lugs 1103 allow balancing in position during rotation, which can prevent the movement by gravity of the active part 11 only on the spring sheet 30a, 30b. The clearances necessary for rotation are thus partially guaranteed by these balancing lugs o and they relieve the spring plate of the weight of the active part in certain angular positions of the active part 11 with respect to the supports 13A, 13B.

By an element "integrated in rotation" with another element, it is understood that if one element rotates according to the axis of rotation X, the other element rotates according to the axis of rotation X. Thus, in this embodiment, if the active part 11 rotates with respect to to the support 13a, 13b, the leaf spring 30a, 30b with the active part 11 rotates along the axis of rotation X with respect to the support 13a, 13b and the cylindrical part 31a, 31b rotates along the axis of rotation X with the corresponding support with with respect to the active part 11.

In this represented example, the leaf spring 30a, 30b deforms radially with respect to the axis of rotation X but could also, according to another example of the not shown rotation mechanism, deform parallel to the axis of rotation X.

In this example of this embodiment, the notch 300 of the spring blade 30 is a rounded projection and the notches 311 of each cylindrical part 31a, 31b are each a gap or a complementary rounded notch between the teeth 312 of the cylindrical part. 31a, 31b. In this case, in this example, the notches 311, of each cylindrical part 31a, 31b, undulate with the teeth 312 on at least a part of the inner peripheral surface of the support element 130 of the support 13. In this example, the notches 311 of the cylindrical part 31a, 31b, undulate with the teeth 312, over 360°, or rather, over the entire internal peripheral surface of the support element 130. In this example, the leaf spring 30a, 30b is located radially inside the cylindrical part 31a, 31b.

According to another example not shown, the spring blade 30a, 30b is axially housed on a radial surface of the end 113 of the active part 11 and includes its notches 300 that extend from this part towards the notches 311 of the support 13a, 13b, being located axially facing the outside of the cylindrical part 31a, 31b.

In this represented example, each leaf spring 30a 30b comprises a plate that in turn comprises at least one portion that extends longitudinally in a flat manner and a deformed part that forms the notch 300. In this case, the leaf spring comprises two flat portions and the deformed part that forms the 300 The notch is between the two flat portions.

In this represented example, each cylindrical part 31a, 31b is an internal peripheral part 130 of the corresponding support 13a, 13b and each spring blade 30a, 30b comprises, in this example, a stop 303i to be integral with the active part 11. In this case , each spring sheet 30a, 30b comprises two stops 303i each forming a hook to be anchored in a housing 113i of the active part 11. The notch 300 of each spring sheet 30a, 30b, in this case, a rounded projection, is located roughly in the middle between the two 303i bumpers.

The housings 113i of the first leaf spring 30a and the second leaf spring 30b are each respectively formed on the outer periphery of the first end 113a and the second end 113b. Each housing 113i of the stops 303i of each spring blade 30a, 30b thus makes it possible to hold the spring blade 30a, 30b radially and axially with the walls of the support element 130.

In this example, the first leaf spring 30a and the second leaf spring 30b are each elastically mounted under tension by having their hook-shaped stops 303i each in a housing 113i of the active part 11.

In figure 1C, it can be seen in the section that each housing 113i allows the deformation of the spring sheet 30a, 30b by allowing the planar portions that extend longitudinally in a planar manner from the plate to deform radially towards the X axis deforming to the the legs of the hooked stops 303i into the housing 113i at the same time. In particular, the leaf spring thus comprises two supports that bear against two projections that extend from each housing 113i to guide the deformation of the leaf spring. . These two projections extend outwards from the outer peripheral surface that comprises the housing between the corresponding hook and the notch 300 of the spring sheet. Thus when the active part 11 rotates with respect to the two supports 13a, 13b, initially each spring sheet 30a, 30b is elastically compressed by sliding its notch 300 against an edge of a notch 311 of the cylindrical part 31a, 31b until it comes against a tooth 312 between two notches 311 of the cylindrical part 31a, 31b while the spring sheet 30a, 30b is elastically deformed by compression and bending by its bearings on the projections of the support, each one forming a support so that the spring sheet is deformed. This deformation is therefore controlled and is also radial with respect to the axis of rotation, allowing rotation in both directions of rotation. Second, each spring sheet 30a, 30b elastically expands by sliding its notch 300 against an edge of a notch 311 until it is at the bottom of the notch 311 of the cylindrical part 31 a, 31 b.

Figure 2 represents a second example of a portion of a notched rotation mechanism 3 of the first embodiment, which can replace the first and/or second rotation mechanism 3a, 3b.

The rotation mechanism 3 is identical to the first and second rotation mechanisms 3a, 3b except with respect to the following characteristics:

In this second example, the spring blade 30 of the rotation mechanism 3 is integral in rotation with one of the two supports, referenced support 13, and the cylindrical part 31 is integral in rotation with one end 113 of the active part 11, different from those ends 113a and 113b of the first example.

The spring sheet 30 is also located radially on the outside of the cylindrical part 31 and therefore the cylindrical part 31 comprises notches 311 and teeth 312 that undulate on an outer periphery and not on an inner periphery as in the cylindrical part 31a , 31b of the first example.

In addition, the end 113 of the active part 11 comprises an opening 113C which passes through and opens out at the end 113 and the support 13 closes the opening 113C.

Furthermore, the spring blade 30 is different because it includes, in this example, a stop 303a to be integral with the support 13 and not a hook-shaped stop 303i to be integral with the active part 11 as in the first example. In this case, the stop 303a is an opening, called the stop opening 303a, located at a first longitudinal end, traversed by a lug 133a that forms part of the support element 130 of the support 13. The stop opening 303a corresponds to the shape of the stud 133a. Therefore, the stop opening 303a passes through a first flat portion of the lamella in this example. The spring blade 30 also comprises a guide stop 335b, in this case a peripheral surface that surrounds a guide opening 335 located at a second longitudinal end opposite the first longitudinal end. The guide opening 335 is located in the second flat portion of the leaf. The guide opening 335 extends longitudinally in the flat portion of the sheet cooperating with a guide stop 133b of the support 13, in this case a guide lug 133b that passes through the guide opening 335. In this example, the guide lug 133b forms part of the support element 130 of the support 13 but can form part of the active part as in a second example represented in figure 3 described in detail below. The notch 300, in this case a rounded projection, lies between the stop opening 303a and the guide opening 335, approximately in the middle. Therefore, the leaf spring also comprises two supports that rest on two shoulders of each guide stop 133a, 133b, each forming a support for the leaf spring for its deformation. The spring sheet therefore comprises two stops that rest on the two shoulders and the notch is located between the two stops that allow the deformation to be controlled.

According to another example, not shown, of the notched rotation mechanism 3, the notches 311 of the cylindrical part 31 undulate with the teeth 312 on at least part of the inner peripheral surface of the end 113 of the active part 11. In this not shown example , the spring blade 30 can therefore be located radially inside the cylindrical part 31 or at least in its notches 300.

According to the example not shown, in which the spring blade 30 is deformed parallel to the axis of rotation, the notches 311 of the cylindrical part 31 undulate with the teeth 312 on a radial surface of the end 113 of the cylindrical part 31 corresponding in this example at one end of the active part 11.

According to another example not shown, the cylindrical part 31 includes projections that form notches and the spring sheet 50 is a lamella that has flat portions and a hole that forms a notch located in an angular position in one of the projections that form the notches. of the cylindrical part 31 and because each end of the notch-forming gap extends from the flat portions of the spring sheet, it is adapted to elastically deform the spring sheet by bending by resting on a notch-forming protrusion of the cylindrical part to pass from a protrusion to another protrusion that forms a notch in the cylindrical part. In other words, in this example, the teeth 312 and the hollow 311 of the cylindrical part can be identical in this represented example except that it is the teeth 312 that form the notches and the spring sheet comprises a hollow instead of the protrusion for form a notch that receives a tooth from the cylindrical part.

In this second represented example, when the active part 11 is rotated with respect to the support 13, the spring sheet 30 will initially deform from an initial position in which the active part 11 was stable with respect to the support 13, to a deformed position that progressively supports. the notch 300 against a tooth 312 adjacent to the notch 311 receiving the notch 300 in the initial position. In a second moment, the projection of the notch 300 re-enters the neighboring hollow notch 311 thus allowing the spring sheet to pass from the deformed position to the initial position in a new hollow 311. When passing from the initial position to the position deformed, the spring blade 30 will elastically deform by bending, in this case radially, bringing its second end closer to the guide lug 133b sliding in the guide opening 335. When passing from the deformed position to the initial position, the notch 300 of the leaf spring 30 will re-enter a notch 311 returning to its initial position and moving its second end away from the guide lug 133b sliding in the guide opening at 335. Therefore, this deformation is controlled and is also radial with respect to to the axis of rotation, which allows it to rotate in both directions of rotation.

Thus, each cooperation of the notch 300 with the complementary notches 311 form a stopping means for positioning said active part 11 according to a plurality of stable angular positions with respect to the support 13.

FIG. 3 partially represents a third example of electrical outlet accessory 1' represented without its electrical switchgear mechanisms 12 according to the first embodiment. This third example differs from the second example of the first embodiment in that the electrical socket accessory 1' is a multiple socket whose support 13' comprises a male electrical switchgear mechanism 12, not shown. That is to say, in this example, the electrical socket accessory 1' does not include the external power cable and the support 13' does not include any feet. The electrical outlet accessory 1' comprises, in this example, an electrical connection device that allows the plugs of the electrical switchgear mechanisms 12 of the active part to be connected to the respective plugs of the male electrical switchgear mechanism 12 of the support 13', by for example, by electrical cables, or by a system of pivoting contact arms with the support 13'. The electric cable has the advantage of not causing an electric arc or electrical fault with each rotation.

The third example is similar to the second example except for the differences described below.

In this third example, the active part 11' surrounds the support 13'.

In this third example, the active part 11' comprises three reception wells 111A oriented differently from each other, such as a triplet. The active part 11' could comprise a single well that would allow it to have a rotary intake. The active part 11' is represented in figure 3 without a half-shell and without its electrical switchgear mechanisms 12 so that the notched rotation mechanism 3' can be seen there.

The notched rotation mechanism 3' is similar to the first example and differs from the second example in that the support 13' comprises the cylindrical part 31 that includes notches 311 at one end opposite the male pins of the electrical switchgear mechanism 12 and therefore in which the active part 11' comprises the spring blade 30' which in turn comprises the notch 300. The previously described variants on the rotation mechanism with notches 3a, 3b in the first and in the second example are also compatible with this third example.

Furthermore, in this third example, it can be seen that the cylindrical part 311 extending from the support element 130' comprises a rotation stop 134 that limits the rotation of the active part 11 on the support elements 130 to 180°. This anti-rotation stop 134 bears against the half-shell, not shown, of the active part 11'. Therefore, the cylindrical part 311 comprises in this third example notches 311 only over 180°. Of course, the rotation of the active part 11 with respect to the support 13' can take place over 360° minus X degrees corresponding to the rotation stop 134 by including notches 311 in 360° of the cylindrical part 311.

Figure 4 represents an example of a second embodiment of the electrical socket accessory 2.

The electrical outlet accessory 2 comprises an active part 21 of a multi-electric switchgear block, similar to the first example in figure 1, elongated along an X axis, which internally houses a plurality of electrical switchgear mechanisms 12 such as outlets or a switch similar to those of the first embodiment.

The electrical socket accessory 2 comprises a support 23 different from the first example of the first embodiment in that in this example the electrical socket accessory 2 comprises nothing more than a single support 23 whose axis X is perpendicular to a support, for example , vertical with respect to a table. This example of this second embodiment has the advantage of having a single rotation mechanism 5 and therefore does not present problems of torsion sensation in the event of a malfunction of one of the two rotation mechanisms of the first example of the first mode of embodiment. realization. However, the electrical socket accessory 2 of this second embodiment can be a multi-electrical switchgear block such as in the example of figure 1 or a multiple socket of the example of figure 3 but it has a rotation mechanism 5 between the support 23 and the active part 21 different from the first embodiment, described in detail below.

Figures 5A to 5C show an example of a notched rotation mechanism 5 according to the second embodiment of the electrical outlet accessory 2.

In this second embodiment, the notched rotation mechanism 5 comprises a leaf spring 50, which is a leaflet that at least partially surrounds the axis of rotation X. In this case, in this example, the leaf spring 50 surrounds the axis of rotation. 360° rotation. In this example, the lamella is a washer that surrounds the axis of rotation by 360° but could be, according to another example, a crown.

In this example, the leaf spring 50 comprises several notches 500, which in this case are regularly distributed to allow different mounting positions and a balancing of the rotational torque sensation. In this case, the notches 500 are at least two and in this example two in number, a first notch 500a diametrically opposite a second notch 500b.

The spring sheet therefore comprises two flat portions that form the washer and each deformed part that forms a notch 500 is located between the two flat portions.

In this example, the notches 500 are, as in the examples of the first embodiment, a rounded protrusion but they could also be a hollow as explained in the first embodiment.

In this example, the leaf spring 50 is deformed parallel to the axis of rotation X, but could be deformed as in the examples of the first embodiment perpendicular to the axis of rotation X.

The notched rotation mechanism 5 comprises a cylindrical part 51 having notches 511 undulating with teeth 512 between each notch 511 on a radial surface of the cylindrical part 51 different from the shown examples of the first embodiment in which the grooves 511 undulate with teeth 512 on a peripheral surface. Each gap 511 is in the shape of a conical portion that widens from an internal diameter of the cylindrical part 51 toward an external diameter of the cylindrical part 51. The notches 511 and the teeth 512 are rounded to form waves that undulate angularly along the the radial surface of the cylindrical part. part 51, in this case in this example about 360°.

The cylindrical part 51 also includes a rotation stop 514 that makes it possible to limit the rotation of a first element integral in rotation with the cylindrical part 51 with respect to a second element integral in rotation of the spring blade 50. This rotation stop 514 comes from both butt against another butt of the second element.

In this example, the leaf spring 50 is therefore axially adjacent to this radial surface of the cylindrical part 51 and deforms axially and elastically by bending when the cylindrical part 51 rotates with respect to the leaf spring 50.

Thus, in an initial position, called stable, the first notch 500a and the second notch 500b are each located respectively in a first recess 511a and in a second recess 511b each forming a notch 511.

When the cylindrical part 51 is rotated with respect to the leaf spring 50, the leaf spring 50 will initially deform axially from its initial position towards a deformed position, abutting each first notch 500a and each second notch 500b against a tooth 512 adjacent to the first gap. 511a and to the second gap 511b. In Second, each projection of the first notch 500a and of the second notch 500b will re-enter the hollow notch 511 adjacent respectively to the first hole 511a and the second hole 511b, thus allowing the spring sheet 50 to pass from the deformed position to the starting position.

When going from the initial position to the deformed position, the spring blade 50 will elastically deform by bending, in this case axially, resting its notches 500a and 500b on the teeth 512 and against the axial stops 503a, 503b explained in detail below. . The two axial stops each form a support for the deformation of the spring sheet. Each notch is located between these two axial stops.

When passing from the deformed position to the initial position, the notches 500 of the spring sheet 50 will enter a notch 511 returning to their initial position. Therefore, the spring sheet 50 is mounted in a housing that allows freedom of bending;

In the event that the leaf spring 50 is deformed perpendicular to the axis of rotation X, the leaf spring 50 comprises separate portions of the cylindrical part 51, for example, at the level of the stops to allow the deformation of the leaf spring 50.

The spring blade 50 is mounted in this example of this embodiment integral in rotation with the active part 21, which is therefore the second element, and the cylindrical part 51 is mounted integral with the support 23, which is therefore the first element. . In particular in this example, the cylindrical part 51 is one end of the support 23.

The leaf spring 50 comprises at least one axial and rotation stop 503a, 503b to prevent its rotation and to rest axially with respect to the second element that houses it, in this case with respect to the active part 21. In this case the leaf spring 50 it comprises a first stop 503a and a second stop 503b that extend axially from the part of the washer, in the opposite direction to the first notch 500a and the second notch 500b. In particular, the stops 503a, 503b and the notches 500a, 500b are angularly distributed alternately and regularly.

Figure 6 schematically represents an exploded three-dimensional view of a portion of the electrical outlet accessory 2 according to the second embodiment.

In this figure 6 it can be seen that the active part 21 also comprises two lower 210B and upper 210A half-shells. In this example, the support 23 comprises the cylindrical part 51 that is surrounded by the ends of the two lower half-shells 210B and the upper half-shell 210a, together forming the housing of the spring sheet 50.

Figure 7 schematically represents a three-dimensional view in partial section of a portion of the electrical socket accessory 2 according to the second embodiment. In this figure 7 the upper half-shell 210A is not shown and the lower half-shell 210B of the electrical socket accessory 2 is cut according to a plane perpendicular to the X axis of rotation.

The leaf spring 50 includes a guide stop 535b to guide the deformation of the leaf spring 50 cooperating with a guide stop 235 of the support or of the active part. In this case, the spring blade 50 comprises a central opening 535 which, with its peripheral surface surrounding the opening, forms the guide stop 535b and the support 23 comprises a guide stop 235 formed by an axially extending cylindrical centering portion. inside the central opening 535 thus centering the spring sheet 50 to guide it during its installation and its elastic deformation by bending.

The support 23 comprises a neck 25 to receive a semicylindrical internal shoulder 215A of the upper half-shell 210A and another semicylindrical internal shoulder 215B of the lower half-shell 210B visible in FIG. 8.

Figure 8 schematically represents a three-dimensional view in partial section of another portion of the electrical outlet accessory according to the second embodiment. In this figure 8 the support 23 is not shown and the lower half-shell 210A of the electrical socket accessory 2 is cut according to an angular plane with respect to the axis X of rotation.

The active part 21 comprises at least on one of its half-shells 210A, 210B some support points 214 visible in figure 8, for example, in stops with the anti-rotation stops 503a and 503b thus allowing the sheet to spring 50 flex elastically when its two notches 500 are abutted against teeth 512. Furthermore, in this example, each half-shell 210A, 210B includes flexure end stops 2140 to allow guiding the shape of the flexural deformation of the flexure. spring sheet 50 in order to prevent it from flexing in a plastic deformation. In fact, the stops at the end of the bending 2140 in the form of support ribs have an axial height dimensioned to provide the necessary and sufficient clearance for the deformation of the spring sheet 50.

Thus, the spring sheet 50 is sandwiched between the cylindrical part 51 comprising notches 511 and the support points 214.

It can also be seen in figures 4 and 8 that the active part 11 comprises in this example a trim 211 as in the first example of the first embodiment, which protrudes from the upper half-shell 210A. The trim 211 defines a plurality of wells 111A for receiving the electrical switchgear mechanisms 12, in this case current plugs, aligned along the X axis of the active part 11.

According to another example of this embodiment, not shown, the spring blade 50 is integral with the support and the active part includes the cylindrical part that includes the notches.

According to another example of these embodiments, not shown, the accessory includes several rotation mechanisms, for example, it includes one between a second support and the active part, or even the accessory also includes a rotation mechanism between two rotating portions, one with respect to to the other of the active part that allows to orient the electrical switchgear mechanisms in different angular orientations. The active part can comprise several half-shells, especially in the case of two rotating portions. The two portions of the active part rotatable with respect to each other can be oriented along other axes of rotation, for example perpendicular to the axis of rotation X.

According to another example of these embodiments, not shown, the support can also comprise one or more electrical switchgear mechanisms.
