Description

The present invention relates to a device for connecting at least one equipment to a socket fixed on a flat support surface, the device comprising a connecting element adapted to engage electrically and mechanically with the socket and being connected to at least one equipment connector.

It is common to use sockets fixed on flat surfaces such as wall outlets and protruding perpendicular or substantially perpendicular to these surfaces, especially in the case of connection to telecommunication networks or transfer energy.

An example of such a device is described in GB-A-2,374,211, which is considered to be the closest state of the art.

The jacks used are usually standard jacks, protruding or recessed, arranged on residential walls.

In the case of the switched telephone network deployed in France and known as the RTC, the telephone equipment connection sockets are standard sockets, called PTT type, having a square face approximately 7 cm side with a female plug. generally shaped connection of inverted T forming a keying element.

The development of telecommunication equipment as well as the increase in electrical energy requirements result in a large number of equipment being connected to each socket.

For example, it is common to connect to the same phone jack type PTT, an answering machine, a phone and a computer modem.

In the case of the RTC network, these different devices are connected to the wall socket by so-called "nesting" sockets, each having a male connector and a female connector, so as to be electrically and mechanically engageable with each other.

An example of such a socket comprising embedded electronics, is described in particular in document FR-A-1 135 218.

Such an arrangement results in the weight of the various connection devices being based solely on the plug of the connection device engaged with the wall socket.

This causes a mechanical instability that can result in particular in breaking the electrical connection and therefore the connection with the PSTN network.

In addition, such an arrangement has a large size, often annoying and unsightly.

In addition, some equipment has sockets in different formats. Their connection therefore requires either the use of an adapter engaged in the socket with the same disadvantages of space and stability, or the replacement of the socket which requires special skills.

Replacement of the socket may also be necessary for security reasons, for example following partial damage to the housing exposing the connection to manipulation by users.

The same problems arise in the case of energy transfer wall outlets with which it is commonly used connecting devices known as "multi-socket" or adapters.

These connection devices comprise a plug designed to engage with a female wall socket, and a plurality of female sockets for connecting a plurality of devices or connecting to sockets of different sizes.

As previously, it appears that only the plug ensures the mechanical connection with the wall outlet, resulting in the same inconvenience of instability, bulk and aesthetics as in the case of the RTC network.

The security problem is also critical, the handling of energy transfer connectors inducing high risks.

It therefore appears that today there is no connection device to a socket fixed on a flat surface, allowing the connection of a plurality of equipment and having a high mechanical stability, a small footprint and high security .

The object of the present invention is to solve these problems.

To this end, the subject of the invention is a device for connecting at least one equipment to a socket fixed on a flat support surface and extending projecting therefrom, as defined in claim 1. .

The device of the invention thus provides a stable mechanical connection with the plug via the connecting element and the surface support plane in contact with the flat bearing face, and a connection to different thicknesses and in accordance with varying relative orientations.

This device also allows the connection with one or more devices in the same format or different formats thanks to the connectors arranged on its housing.

Moreover, it makes it possible to limit the overall bulk and to increase the safety of the users due to the recovery of the plug.

Other features of the invention are set forth in the secondary claims.

Figure 1 is an exploded view of a device for connecting a plurality of equipment to a telephone jack.

Conventionally, the telephone jack designated by the general reference 2, comprises a protruding casing 4 of generally parallelepipedal shape, having on its front face, a female connection plug 6 in the general shape of inverted T oriented vertically and forming a keying.

The socket 2 is fixed on a flat support surface 8, such as for example a wall, so that the female plug 6 extends in a direction perpendicular to or substantially perpendicular to the surface 8.

Conventionally, such a projection has approximately a square front face of about 7 cm side and a thickness relative to the flat support surface 8, of the order of 2 to 3 cm.

Such a plug 2 is commonly referred to as an "apparent female standard PTT socket".

The connecting device of the invention, designated by the general reference 10, comprises a housing 12 covering the socket 2 of generally parallelepipedal shape.

The housing 12 has on its front face a plurality of connectors for equipment, designated by the general reference 14 and formed, for example, connectors of different types such as PTT, RJ11, RJ45 or USB.

Of course, the different connectors may be arranged on different sides of the housing 12.

The plurality of connectors 14 is electrically connected in a manner not shown, to a connecting element 16 formed by a male connector plug in the general shape of an inverted T, intended to engage electrically and mechanically in the socket 6 of the socket 2.

The connection of the element 16 with the socket 6 thus makes it possible to transmit the electrical signals between the socket 2 and the plurality of connectors 14.

Advantageously, the connection element 16 is electrically connected to the plurality of connectors 14 by unrepresented links and by means of an electronic unit U adapted to effect processing of the electrical signals delivered by the socket 2.

In one embodiment, the electronic unit U comprises a conversion module adapted to convert the received electrical signals into other types of signals. For example, the electronic unit U comprises a modem of conventional type and is adapted to receive from socket 2, a high-speed data information signal of the so-called "xDSL" type and convert it into an information signal of type "Ethernet" which will be delivered to a corresponding connector, such as an RJ45 connector, of the plurality of connectors 14.

As a variant, the electronic unit U comprises a noise filtering module on the various electrical signals received, or a filtering module adapted to separate a plurality of information signals simultaneously transmitted by the socket 2 and each delivering on a connector. different.

Finally, in the embodiment described, the device 10 comprises interface elements designated by the general reference E and comprising human-machine interface elements such as a loudspeaker E1 and a setting of corresponding sound level E2, an E3 diode overhead projector, a communication interface E4, such as for example a frequency modulation radio wave transceiver antenna, or an E5 interface for an audio-video link.

The electronic unit U is adapted to control the interfaces E, in particular according to information contained in the electrical signals coming from the socket 2.

The cover housing 12 also has a plug Pwr for connection to an external power supply for supplying the connection device 10 and in particular the unit U.

However, the cover box 12 may also include a housing for a rechargeable battery or a set of batteries for powering the unit U.

Many applications and variations of such an arrangement may be contemplated but will not be described here.

In the following, it is considered that the connecting element 16 has a general axis X-X, corresponding to the direction perpendicular to the two directions defined by the general shape of T.

The cover housing 12 has a flat rear support surface 18 intended to be in contact and in abutment with the flat support surface 8 when the cover housing 12 is positioned on the socket 2.

Advantageously, the cover housing 12 has a rear portion 19 of elastic material, whose rear end defines the flat bearing face 18, so as to ensure an optimum connection with the flat support surface 8. This arrangement allows to compensating for differences in orientation between the flat bearing face 18 and the flat support surface 8 as well as surface imperfections, especially in the case of sockets extending in a direction not completely perpendicular to the flat support surface 8 .

The elastic portion 19 thus allows a flexible connection between the flat bearing face 18 and the flat support surface 8 to allow, for example the passage of cables.

In addition, the cover box 12 has at the rear a recess 20 offset laterally with respect to the median plane of the housing 12, extending from the flat bearing face 18 perpendicularly or substantially perpendicularly, and of a volume sufficient to receive the socket 2.

Thus, when the cover housing 12 is positioned so that the flat bearing face 18 is in contact with the flat bearing surface 8, the housing 4 of the socket 2 is fully inserted into the recess 20.

In the embodiment described, the recess 20 is of a size and shape adapted to the size and shape of the housing 4 of the socket 2, so that the faces of the recess 20 form surfaces support, adapted to be arranged against the side faces of the housing 4 of the socket 2, forming support surfaces.

The faces of the recess 20 thus allow a mechanical connection with the socket 2 when the latter is protruding, so as to make the cover housing 12 secured to the socket 2.

In the embodiment described, the connecting element 16 is integrally mounted on a support 22 in the form of a thick disk perpendicular to the axis XX of the connecting element 16, or in parallel with the flat bearing face 18.

This disc 22 has on its edge four radial notches 24A, 24B, 24C and 24D diametrically opposite two by two. The notches 24A and 24C are arranged on a vertical diameter of the disk and the notches 24B and 24D are arranged on a horizontal diameter of the disk.

The device also comprises a frame 26 thick, extending parallel to the flat bearing face 18.

The frame 26 has a circular central opening 27 provided to receive the disc 22 without significant play.

The frame 26 provides a mechanical connection with the disk 22 of such a nature as to allow only the rotational displacement of the disk 22 in the opening 27 of the frame 26 and in the plane formed by the latter.

Such a displacement is obtained in a conventional manner, for example by adapting the diameter of the disc 22 and the opening 27 of the frame 26 in order to make a close contact between the edge of the disc and the edge of the opening and by means of fixing tongues 28 covering the peripheral zone of the opening 27 on each face of the frame 26, so as to prevent the displacement of the disk 22 in translation relative to the frame 26 along the axis XX.

Furthermore, the frame 26 comprises a lug 29 movable in translation in the frame 26 and in a radial direction relative to the X-X axis. This lug 29 has a general shape conjugate to the shape of the notches 24A, 24B, 24C and 24D, so as to engage therewith. It is connected to a spring 30 which tends to make it penetrate into the opening 27.

The arrangement of the lug 29 and the spring 30 provides the mechanical connection with one of the notches 24A, 24B, 24C and 24D of the disc 22, so that the disc 22 is rotatable relative to the frame 26 between four stable positions of different orientations with respect thereto and corresponding in the embodiment described, at four orthogonal orientations to each other.

The disk 22 thus forms a support for the connecting element 16 rotatable relative to the cover housing 12 in a plane parallel to the flat bearing face 18, between several stable positions of different orientations relative to the housing of recovery 12.

The frame 26 has a size and a general shape corresponding to the size and shape of the recess 20, so as to be inserted therein.

In addition, the frame 26 has lugs 32 disposed on several of its lateral faces projecting and perpendicular to them.

Correspondingly, the recess 20 has grooves 34 parallel to its general axis and intended to receive the projecting lugs 32. The engagement of the projecting lugs 32 in the grooves 34, thus allows to guide the frame 26 in translation along the the recess 20.

In addition, the frame 26 has a cylindrical recess perpendicular to one of its lateral faces, receiving a helical spring 36 which exerts a pressure on a ball 38, so as to push it outside the cylindrical recess or any at least to make it protruding from the face on which is disposed the cylindrical recess.

Correspondingly, the recess 20 has hemispherical cavities 40 disposed on one of its faces and aligned along the axis of said recess 20 and at the level of the ball 38.

Thus, the frame 26 is movable in translation along the recess 20, between several different stable positions of depression, which positions are materialized by the engagement of the ball 38 in the cavities 40 under the effect of the pressure exerted by the spring 36.

The frame 26 thus forms a support for the connecting member 16 movable in translation relative to the cover housing 12 to move along the recess 20 between several different stable positions of depression.

The disc 22 and the frame 26 thus form an arrangement allowing a connection of the device 10 to different thicknesses and in different relative orientations.

Thanks to this arrangement, the connecting element 16 is mechanically connected to the cover housing 12, via the disk 22, connected to the frame 26, itself connected to the recess 20.

In addition, the plug 2 is fully inserted into the recess 20 of the cover housing 12, to reduce the overall size and to be masked for reasons of safety and aesthetics.

The mechanical connection between the cover housing 12 and socket 2, is provided by the connecting element 16 mechanically engaged in the socket 2 and mechanically connected to the cover housing 12, and by the flat bearing face 18 in contact with the flat support surface 8, so that the mechanical stability of the arrangement is ensured.

The mechanical connection is further reinforced by the flat faces of the recess 20 adapted to be in contact with the cover casing 4 of the socket 2.

Referring to Figure 2A, there is shown a sectional view of the device 10 according to the plane II of Figure 1.

In this case, the frame 26 being initially in its minimum depression position, the connecting element 16 projecting rearwardly is first mechanically and electrically engaged in the socket 6.

By pushing the housing 12 toward the surface 8, the movable frame 26 is then placed in a maximum depression position in the recess 20, as shown in FIG. 2A, to allow the insertion of the housing 4 of the socket 2 in this recess.

The ball 38 is engaged in the hemispherical cavity 40 corresponding to this driving position, under the pressure of the spring 36, so that to ensure the mechanical connection between the frame 26 and the cover housing 12.

As has been indicated previously, the flat bearing face 18 then bears against the flat support surface 8.

It can thus be seen in this figure that the displacement in translation of the frame 26 along the recess 20 allows the connection to a projecting catch while ensuring the total recovery thereof as well as the mechanical connection.

Figure 2B shows a sectional view along the plane II of Figure 1, when the device of the invention is connected to a recessed socket or slightly protruding.

In this sectional view, the connecting element 6 is engaged in a recessed or slightly projecting socket 2 so that the connecting element 16 is mechanically and electrically engaged in the socket 6.

In this example, when this engagement is made, the face 18 bears on the surface 8 while the frame 26 remains positioned according to its minimum depression along the recess 20, the mechanical connection being ensured, as previously, by the engagement of the ball 38 in the hemispherical cavity 40 under the pressure of the spring 36.

The device of the invention thus allows the connection to a recessed socket or slightly protruding, while providing the mechanical connection through the connecting element 6 connected to the cover housing 2 and the flat bearing face 18 in contact with the flat support surface 8.

Figure 3A shows a partial sectional view along the plane III of Figure 1, illustrating the positioning of the cover housing 12 in a first orientation.

In this figure, the covering device 10 has a horizontal general orientation.

The disc 22 is positioned in turn so as to provide the connecting member 16 an orientation such that the T extends vertically. The mechanical connection of the disk 22 with the frame 26 is ensured by the engagement of the pin 29 in the corresponding notch 24A, under the pressure of the spring 30.

In FIG. 3B, the device of the invention is arranged in another orientation and extends along a general vertical axis.

However, the disc 22 is still arranged so that the axis of the connecting member 16 extends vertically.

In this configuration, the mechanical connection between the disk 22 and the frame 26 is ensured by the engagement of the lug 29 in the notch 24B of the disk 22, under the pressure of the spring element 30.

It therefore appears that the use of a mobile support rotated relative to the housing, between positions of different orientations, allows different positioning of the device 10 with respect to the connecting element 16.

Such a solution allows the adaptation of the positioning of the device 10 to environmental elements such as for example walls or the floor, as well as the connection to various orientations.

FIG. 4 represents a partial sectional view of a variant of the device of the invention, according to plane III of FIG.

Indeed, in this embodiment, the recess 20 comprises elastic strips 60 arranged in the greater length of its internal faces.

These strips 60 are fixedly connected at one end to the cover housing 12, and their convex intermediate portion tends to protrude into the recess 20.

Such an arrangement is likely to exert a holding pressure on corresponding lateral faces of a projecting engagement engaged in the recess 20.

This arrangement has the advantage of allowing adaptation to different types of plugs, sizes and shapes, while providing an additional mechanical connection between the recess 20 and the socket.

Figure 5 shows a sectional view from above of another variant of the device of the invention.

In this embodiment, the formed arrangement of the disc 22 and the connecting member 16 has a blind hole 68 extending along the X-X axis from the free face of the disc 22.

The end of the orifice 68 opens laterally onto the lateral faces of the element 16 by two lumens 69.

This orifice 68 accommodates two pawls 70 extending parallel to the axis XX and pivoting about pivots 73.

The pawls 70 are in the form of bars whose ends on the side of the connecting element 16 each comprise a prominent beak 72 extending laterally in a slot 69 and, on the other side of the pivot 73, a part of actuation 74.

Each spout 72 has a beveled front face 75 and a flat retaining face 76 parallel to the disc 22.

Nozzles 72 are projecting out of the slots 69 by springs 77 acting on the parts 74.

Such an arrangement makes it possible to lock the positioning of the connecting element 16 when it is engaged in the socket 2, by the engagement of the flat faces 76 of the slats 72, with the internal face of the front wall of the socket 2 .

The introduction of an unlocking key 78 in the orifice 68 makes it possible to move the parts 74 of the pawls 70 to retract the nozzles 72 inside the connecting element 16, which makes it possible to separate this element 16 take 2.

Figure 6 shows a rear view of another embodiment of the device of the invention.

In this embodiment, the recess 20 of the cover housing 12 is of a size substantially greater than the size of the socket referenced 2 in the previous figures.

In addition, the recess 20 has on its inner face parallel to the bearing face referenced 18 in the previous figures, a groove 80 in the form of a quarter circle with an undercut section.

The connecting element 16 is integral with a support element 82 conjugate groove 80 and adapted to move along this groove.

Thus, the support element 82 moves between two extreme positions making it possible to obtain a continuous variation of the orientation of the connecting element 16 between two extreme orientations at 90 ° to one another.

Such an embodiment has the advantage of allowing easy adaptation to different orientations.

Figure 7 shows a perspective view of another embodiment of the invention.

In this embodiment, the connecting device 10 is adapted to be positioned on a base 90 having a socket 92 formed of a female PTT plug, fixed on a flat support surface 94 and sunk into it.

This base 90 is mobile and is adapted to be connected to a telephone wall jack 2 and a telephone T.

The connection device 10 according to the invention allows, as previously, to connect to the socket 92 while covering it to allow the connection of a plurality of equipment requiring a power supply, with a stable mechanical connection, a minimal footprint and high security.

Finally, FIG. 8 represents a perspective view of a device according to the invention intended for connection to an electrical energy transfer network plug.

As in the previous case, the device comprises a cover housing 100 having a flat bearing face 102 and a recess 104 extending from it perpendicularly or substantially perpendicularly.

The front and side faces of the cover housing 100 have a plurality of connectors designated by the general reference 106.

The recess 104 comprises a not shown connection element, advantageously movable in translation along the recess 104 and in rotation relative to the cover housing 100 in a plane parallel to the bearing face 102.

It thus appears that, just as previously, such a connection device 100 is adapted for connection to an electrical outlet by providing a stable mechanical connection with this socket, and by providing a plurality of connectors for equipment with a minimum space requirement and a great security.

Advantageously, an electronic unit similar to the electronic unit U described above, can be interposed between the connecting element and the plurality of connectors 106.

• des protections contre les surtensions limitant la tension transmise;
• un module de conversion de puissance électrique délivrant une pluralité de niveaux de tension et d'intensité ;
• un modem sur courant porteur séparant informations et énergie électrique ;
• un modem USB ou radio ;
• un émetteur d'ondes radios;
• une interface lumineuse et/ou sonore;
• un élément d'alarme tel qu'un détecteur infrarouge;
• un programmateur permettant de commander l'alimentation des différents équipements;
• une horloge ; et/ou
• un microphone.

For example, such an electronic unit comprises:

• overvoltage protection limiting the transmitted voltage;
• an electric power conversion module delivering a plurality of voltage and intensity levels;
• a powerline modem separating information and electrical energy;
• a USB modem or radio;
• a transmitter of radio waves;
• a light and / or sound interface;
• an alarm element such as an infrared detector;
• a programmer for controlling the power supply of the various equipment;
• a clock ; and or
• a microphone.

Of course, other embodiments can be envisaged as well as arrangements of shapes and variable orientations.

In particular, the connection element to the socket can be an interchangeable removable element to allow connection to different types of plugs.

In addition, a front of the housing having connectors and / or interface elements may be removable and connected to the connecting member or the electronic unit by a multi-point connector or an optical connector.

Such an embodiment makes it possible to modify the connectors and / or the interface elements available on the housing.

Finally, the various equipment connected to the device of the invention may be telecommunications equipment in the case of a connection to an information transfer socket or any type of equipment requiring a power supply in the case of a connection to an electrical energy transfer network outlet.
