Description

CONNECTING DEVICE FOR RECEIVING INFORMATION FROM AN ELECTRICAL LINE INTO A BRACKET OR FOR ISSUING ELECTRICAL LINE INFORMATION The invention relates to an electrical connection device providing a function of a user's choice, such as a function switch or socket function.

A connection device comprises an electrical box forming a receptacle in which at least one electrical wire is placed. The housing is preferably placed in a housing dug in a partition. A core is then placed in the receptacle, so as to form for example a switch or a socket. For practical and aesthetic reasons, the switch or socket must not emerge above the wall in an exaggerated manner, but protrudes only a few centimeters from the wall, usually less than 3cm.

The core includes means for connecting to the one or more wires of the housing. For example, the son or wires in the housing are connected to those of the core by means of a terminal block ensuring the electrical contact by friction. The core is then attached to the housing, for example by means of screws and elastic tabs.

More particularly, the invention is concerned with the field of so-called CPL technology (acronym for line carrier current).

PLT technology includes enabling the exchange of information via so-called domestic electrical power lines that can be found in most homes or offices. It then becomes possible to make a connection for example to the Internet, using the wiring already in place.

Indeed, the function of the domestic power lines is essentially to transmit a current, typically of frequency around 50 to 60 Hz, while the information carrying signals generally have a frequency beyond the kilohertz. Power lines that are subject to certain standards, including the NF C15-100 standard, are unsuitable for carrying a signal carrying information.

The solution used by PLC technology is based on the principle of superposition of two waves: a signal carrying information is superimposed on the current of the line and spreads on the line. The information can thus travel via domestic power lines. A PLC system receiving the signal extracts the information and can transmit it to a suitable device. Thus, there is no need to set up new wiring to propagate information, these passing through the existing electricity network.

The CPL technology makes it possible to install an information exchange network without jobs, large-scale works that would be necessary if a new cabling network were to be put in place. Instead, simply connect a PLC system to the power lines to exchange information.

The applications are multiple. In particular, we can cite the application to home automation for the control of electrical equipment such as heating, lighting or the control of doors, or for the creation of an information sharing network within the same building. We speak of "indoor" application. In this case, the signal carrying the information is a low frequency signal, for example between 3 and 150 kHz. The information travels only on the lines of the building.

One of the applications that tends to develop the most is access to

Internet. The information is transmitted by means of high frequency signals, for example between 1.5 and 80 MHz. The PLC system is coupled to a modem for decoding the analog signal into a digital signal, and vice versa. Thus, when a building's electrical network is connected to the Internet, digital data can travel on power lines. We speak of "outdoor" application.

PLC technology is a great success, particularly in its practical aspect. However, this technology is still young, and many developments are planned. In particular, there is no formal standard yet to provide a framework for the installation of LC systems in homes or offices. Indeed, the power lines for the current are not adapted to carry high frequencies, and thus electromagnetic radiation appears by the electric lines that can interfere with the environment. In return, the waves electromagnetic environment can disrupt the signal, and make the system inoperative. However, many groups or associations are working on the problems caused by this promising technology, such as:

- the IEEE association, which formed the working groups P1575, P1775 and P 1901, dedicated to improving the security and standardization of PLC networks;

- the HomePlug consortium, with around a hundred members, working on debits;

- the association resulting from the OPERA research project of the European Commission.

There are already on the market devices implementing a PLC system, in particular for the application to the Internet. Examples of these are LEAD®, D-Link®, or Devolo®. These devices are in the form of a pair of adapters. A first adapter including plugs for is plugged into a power outlet such as those commonly found in homes or offices. A second adapter is connected to the equipment with which the exchange of information is planned. The adapters then make it possible to pass the information between a power line and the equipment, such as a computer, for example by means of an RJ45 type cable or by Wi-Fi.

WO 02/05451 gives an example of such an adapter placed between the power lines and a modem. GB 2446274 shows another example of an adapter, in which the modem is integrated with the PLC system.

Such adapters have a significant footprint, and emerge from the partition on which they are mounted, which can hinder users. For example, the larger the adapter, the more likely it will be struck by individuals or animals and be unplugged, torn or damaged accidentally. In addition, the clutter of such adapters prohibited to hide behind a piece of furniture. In addition, these adapters are fully visible, and very easy to remove, in the manner of a plug of a power cable plugged into a power socket. Thus, in public areas or in places with heavy traffic, these adapters, relatively expensive, are likely to be stolen.

The document FR 2 856208 proposes to set up a CPL adapter directly in the housing. A terminal block makes it possible to ensure electrical contact between the wires in the housing and the adapter. The adapter is then secured in the housing by means of spacers. Plinths are screwed on the housing to close it and a hubcap is assembled on these bases. The hubcap has an output type RJ 45 so as to form an access socket to an Ethernet type network. The adapter is then behind the hubcap, so that the size of the emerging part of the partition is reduced and the CPL system is hidden, the risk of theft are reduced.

However, such a solution is unsatisfactory.

Indeed, the mounting of the adapter in the housing requires handling for example a fragile electronic card and small parts with tools, in particular a screwdriver, to ensure the contact in the terminal block and the fixing of the bases on the housing. Editing is then made difficult and difficult.

In addition, the access to the network of the assembly of the document FR 2 856208 has a definitive vocation. To remodify the function of the socket, for example to make a switch or a simple socket, it is necessary to disassemble the set and completely change the speaker.

The invention aims in particular to overcome the aforementioned drawbacks, by providing a housing on which a sleeve is assembled by sliding and without tools, the sleeve incorporating a signal processing system, for example implementing the PLC technology.

Figures 12 to 14 are graphical representations of the superposition principle. FIGS. 9 to 11 show a connection device 1 for receiving a signal from an integrated electrical line in a carrier or for transmitting said signal on the line.

By support means here any type of support likely to carry power lines. Thus, it is for example walls, ceiling, floor or trunking and cable trays.

The power line is of the type that can be found in most installations, such as housing or offices, recommended by standard NF C15-100, to conduct an alternating current frequency around 50Hz and a voltage of about 230V.

The device 1 comprises a housing 2 in which a sleeve 3 slides.

The housing 2 finds an advantageous application in the production of a flush-mounting box of electrical equipment to be placed in a brick wall or plasterboard.

The housing comprises a side wall 4 flanking a receiving space 5 for a sleeve 3. The side wall 4 is closed at a lower end by a bottom wall 6, the upper end forming an opening. The housing 2 is then able to receive the sleeve 5 to provide a desired function, as will be seen later. According to the embodiment illustrated in the figures, the section of the housing 2 is octagonal. Alternatively, the section of the housing 2 may be square, rectangular or circular.

At least one opening 7 is made on the housing 2, straddling the bottom wall 6 and the side wall 4. In practice, the housing 2 comprises four openings 7, distributed at 90 °. The openings 7 can be closed by a lid, which is removed at the time of installation. For example, the openings 7 are formed by manual removal of the lid covering them. Thus, only the necessary openings, depending on the axis of arrival of the electrical wires, are disengaged from their operculum, limiting the intrusion of external elements into the housing by superfluous openings.

In the receiving space 5, a wall 8 is formed substantially vertically on the bottom wall 6 around each opening 7. In what follows, the vertical direction is defined as being the direction in which the lateral wall 4 of the housing 2 extends.

Each wall 8 comprising three sections: a first section 9 extends from the side wall 4 of the housing and is extended by a second section 10, a third section 11 joining the side wall 4. Each wall 8 forms a hexagon with three adjacent sides of the side wall 4. The second section 10 of the wall 8 has a vertical dimension greater than that of the other two sections 9, 11, without however exceeding the side wall 4.

Between two adjacent walls 8, the housing 2 comprises four zones 12, distributed at 90 °, to place electrical connectors, not shown here. For more details on the electrical connectors, reference may be made to document FR 2869 732 of the applicant, which gives an example of connectors.

On the upper end of the side wall 4, the housing comprises a flange 13 provided with lugs 14 carrying bores 15, assisting in fixing in the support.

In the receiving space 5, the housing 2 further comprises shelves 16, placed on the side wall 4, substantially parallel to the bottom wall 6. These tablets 16 are for example placed above each opening 7 of the housing 2. Each shelf 16 of the housing 2 comprises a weakened central area 17, for example by means of a cutout 18, surrounded on both sides by a zone 19 stiffened, for example by means of stiffeners 20. It is understood that each tablet 16 will deform preferably on the central area 17.

Stoppers 21 are also projecting on the lateral wall 4, between the bottom wall 6 and the shelves 16, substantially at the level of the larger section 10 of the walls 8.

The housing 2 further comprises a sleeve 3, providing the desired function. The sleeve 3 comprises a shell 22 in two parts: a lower portion 23 and an upper portion 24 forming a cover.

The lower portion 23 comprises a bottom wall 25 from which a side wall 26 substantially vertically forming a connection zone 27 of octagonal shape complementary to the section of the housing 2.

In the connection zone 27, the lateral wall 26 comprises two openings 28, for example at 90 ° to one another, corresponding to the zones 12 for connectors of the housing 2. The lateral wall 26 comprises two tongues 29 rising substantially perpendicularly, placed in front of each opening 28, at a distance from the side wall 26, so as to form an insertion zone 30 between each opening 28 and the corresponding tongue 29.

From the connection zone 27, the sleeve 3 has a shoulder 31: the bottom wall 25 widens to form a housing zone 32 for electronic assembly surrounded by a side wall 33, to an opening.

According to the preferred embodiment, the side wall 26 of the housing zone 32 of the sleeve 3 has an outer surface 34 provided with at least one recess 35, of a size at least equal to that of the shelves 16 of the housing 2. In practice , the side wall 26 has four recesses 34, corresponding to the four shelves 16 of the housing. At least one recess 35 carries a shelf 36 projecting from the side wall 26. According to the figures, two opposite recesses 35 of the sleeve 3 each comprise a shelf 36. The shelf 36 of the sleeve 3 comprises a central zone 37 stiffened for example by means of a stiffener 38 framed on either side by a zone 39 no stiffened. It is then understood that the shelf 36 of the sleeve 3 will deform preferably on the untied zones 39, in a manner complementary to the shelves 16 of the housing 2.

In addition, the side wall 33 of the housing zone 32 of the sleeve 3 comprises lugs 40, cut in the wall 33 and directed into the housing zone 32 of the sleeve 3, to block the electronic assembly as will be seen later.

The electronic assembly is a system 41 for signal processing. According to the preferred embodiment, the processing system 41 implements the PLC technology. The system 41 comprises a circuit 42 CPL, formed of two circuits 43, 44 superimposed printed. Conductive spacers 45 provide the electrical connection between the two circuits 43, 44. The staged configuration of the circuit 42 CPL allows congestion to be limited in a single plane to provide a compact shape.

A so-called lower circuit 43 comprises on a so-called lower face 46 two projecting protruding claws 47. Each claw 47 is formed of a conductive plate, for example metal, folded so as to have three faces: a central face 48 framed on both sides by two side faces 49. In the illustrated example in which the sleeve 3 is of octagonal section, the central face 48 forms with each lateral face 49 an angle less than or equal to 45 °.

The circuit 44 said upper includes on a face 50 said upper, opposite the lower face 46 of the lower circuit 43, means 51 of external connections, for transmitting a signal to an external device or to receive a signal. According to one embodiment, these external connection means 51 comprise a socket 52 for RJ45 type cables. Alternatively, these means 51 may be wireless means, implementing the Wi-Fi or Bluetooth® technology. Three "dels" (color emitting diode acronym) can also be placed on the face 50 of the upper circuit 44. These diodes are mounted for example by soldering to the upper surface 50 of the upper circuit 44, by the so-called surface-mounted components or SMD technique. Alternatively, the diodes are mounted by means of pins passed through the upper circuit 44.

The system 41 of signal processing then makes it possible to travel on the power line information. For this purpose, the system makes it possible at the same time to extract a signal carrying an information superimposed on another signal able to travel on the electrical line, and, conversely, to superpose a signal carrying an information to a second signal. fit to travel on the power line.

Signal carrying an information here refers to the signals used in information exchange technologies. These are, for example, signals used in the context of local networks or the Internet (high-frequency signals, of the order of the mega-hertz), telephone signals or televised signals. These signals can be analog or digital. The principle of superposition is illustrated schematically in FIGS. 12 to 14. In FIG. 12, there is shown a first signal 53 of greater amplitude and of lower frequency than a second signal 54 represented in FIG. 13. In practice, the first signal 53 is the electrical signal able to travel on a domestic power line, typically having a voltage of 230V and a frequency of 50Hz. The second signal 54 is the signal carrying the information. The higher frequency and the lower amplitude of the second signal make it unsuitable for traveling on the domestic power line, especially because of the electromagnetic noise of the machines connected to the line which turn on and off, and energy losses. .

Thus, by superimposing the two signals (FIG. 14), a third signal 55 is obtained capable of traveling on the electrical line. The processing system 41 receiving the two superposed signals can then extract the second signal 54 to retrieve the information. Conversely, the processing system 41 can superimpose the second signal 54 to the first signal 53 to emit it on the power line.

The external device is for example a computer, the power line then acting as a connection to the Internet. A modem may be directly integrated in the sleeve 3 or may be interposed between the sleeve 3 and the computer.

The shell 22 of the sleeve 3 and the housing 2 are made for example of thermoplastic material, such as PET, by injection molding. The shelves 16 of the casing 2 and 36 of the sleeve 3, as well as the lugs 40 of the housing region of the sleeve are preferably elastic, that is to say that they can deform under the effect of a constraint then resume their original position when the constraint is removed.

The signal processing system 41 is placed in the shell 22. More specifically, the signal processing system 41 is slid into the lower part 23 of the shell 22 of the sleeve 3 through the opening 28. The conducting claws 47 are placed in the zone 27 for connecting the lower portion 23 of the shell 22. Each claw 47 of connection is inserted between an opening 28 and a tongue 29, the central face 48 of the claw 47 bearing against the tongue 29. Advantageously, the claws 47 and / or the tongues 29 admit a elastic deformation so that the central face 48 of each claw 47 is pushed towards the opening 28 by the corresponding tongue 29. Advantageously, the conductive claw 47 thus placed is flush with, or even protrudes from, the outer surface of the side wall 26 of the connection zone 27.

The circuits 43, 44 printed are placed in the housing zone 32. For this purpose, the circuits 43, 44 slide on the tabs 40 of the side wall 33 of the housing zone 32, the tabs 40 then deforming to let the circuit 41, 42 CPL. When at least the lower circuit 43 has passed beyond the tabs 40, they resume their position towards the inside of the housing zone 32, blocking the circuit 41, 42 CPL in the shell 22.

The upper part of the shell 22 is then assembled on the lower part 23 so as to close the opening 28. For this purpose, the two 23, 24 parts of the shell 22 comprise holes that are in coincidence, assuring the assembly of both parties. The upper portion 24 protects the system 41 while leaving access to the means 51 external connection.

Other holes are provided on the upper part of the shell 22 and the cover 56 revealing the three diodes of the treatment system 41. In the absence of drilling, a very thin wall positioned on the facade 56 in the axis of the three diodes of the circuit 42 CPL will show the light signals. The diodes then make it possible to obtain visual information on the state of the signal processing system 41: a first diode indicates the electrical connection between the sleeve 3 and the housing 2, a second indicates the recognition of the external device, and more precisely recognizing a receiving element and / or transmitting information carried by the external device, and the third diode indicates the transmission of information. The receiver and / or receiver element of the external device may be an insert, or directly integrated in said external device, configured to be implemented with the system 41 of signal processing.

The assembly of the connection device 1 will now be described. The housing 2 is first embedded in the support. For this purpose, the support is hollowed out with a cavity sufficient to place the housing 2 completely there. The power line generally comprises two to three conductive son grouped in the same sheath. The end of the electrical wires is out of the sheath and is inserted into the housing 2. In accordance with standard NF C15-100, a portion of the sheath also penetrates into the housing 2. The end of the electrical wires is stripped and is contacting the connectors placed in the housing 2, ensuring the electrical contact. To do this, each wire passes over one of the sections 9, 11 of smaller size of the wall 8 to join an electrical connector.

The housing 2 is sealed in the cavity. The collar 13 and the lugs 14 are pressed against a surface of the support, and fixing means can be used in cooperation with the holes 15 of the tabs. A sealant may also be used.

The housing 2 is then at least partially embedded in the support, only a portion, preferably the flange and the tabs, emerging beyond the support. The housing 2 thus provides the intermediate between the power line and the outside.

The sleeve 3 is then assembled on the housing 2. For this purpose, the sleeve 3 slides in the receiving space 5 of the housing 2, so that the conductive claws 47 are in contact with the connectors in the housing 2, the bottom wall 25 of the sleeve 3 coming opposite the bottom wall 6 of the housing 2.

The shoulder 31 of the sleeve 3 bears against the larger section 10 of the walls 8 and against the stops 21. In this way, the zone 27 for connecting the sleeve 3 extends into the space defined by the walls. 8, while the housing zone 32 extends above the walls 8. The dimension of the space defined by the walls may be slightly smaller than that of the zone 27 for connecting the sleeve 3. The walls 8 then have sufficient elasticity to deform and accommodate the zone 27 for connecting the sleeve 3, promoting intimate contact between the claws 47 of the sleeve 3 and the electrical connectors in the housing 2.

The sleeve 3 can then extend entirely into the receiving space of the housing 2. In practice, the sleeve 3 extends partially in the support, the connection zone 27 and at least a part of the housing zone 32 extending into the housing 2. Preferably only the output for RJ45 cables emerges from the housing and support. For example, the sleeve 3 emerges from a few millimeters of the housing 2 and the support.

The sleeve 3 is then locked in the housing 2.

According to the preferred embodiment, the locking is achieved by latching, involving the shelves 16, 36 of the housing 2 and the sleeve 3. Indeed, during the assembly of the sleeve 3 in the housing 2, the sleeve 3 is positioned in such a way that the recesses 35 slide on the shelves 16 of the casing 2. The shelves 36 of the sleeve 3 abut the shelves 16 of the casing 2, before the shoulder 31 of the sleeve 3 comes into abutment in the casing 2. By applying sufficient force, the shelves 16, 36 are deformed, allowing the passage of the sleeve 3 beyond the shelves 16 of the housing 2. The stiffeners 20, 38 of the shelves 16, 36 are such that the passage of the sleeve 3 in the other direction is blocked, unless applying a force greater than that used for the assembly. The sleeve 3 is then wedged between the walls 8 and the stops 21 on the one hand, and the shelves 16 of the housing 2 on the other hand.

Alternatively, the locking sleeve 3 is formed by pivoting at least a portion of the sleeve 3. For example, the sleeve 3 comprises a ring, which pivoting on the sleeve 3 snap on means provided for this purpose 2. The document FR 2 869 732 gives an example of locking by rotation.

A cover 56 serving as dressing can be reported over the sleeve in the housing. The lid 56 comprises an opening 57 to allow access to the socket 52 of the sleeve 3.

The connection device 1 thus formed makes it possible to avoid handling small parts (wires, terminals, screws), which can lead to a bad electrical contact, a simple sliding ensuring contact. The device 1 can be used both for "indoor" applications and for "outdoor" applications.

Furthermore, in prior art devices, screws are generally used to secure the sleeve to the housing, and can unscrew during use, so that the sleeve moves away from the support. Dust or other foreign matter can then accumulate in the housing, damaging the wires and connectors in the housing. In addition, the wires can then be accessible for children's fingers. This is why it is necessary to screw the sleeve regularly, with the risk of rupture already mentioned.

According to the device 1 described, the sleeve 3 is locked in the casing 2, and only a determined force can pull it out, avoiding any unintentional disassembly.

The system 41 of signal processing is blocked in the housing 2 and is hidden by the cover 56, limiting the risk of theft.

The system 41 is also protected in the shell 22 of the sleeve 3, and does not protrude from the support, so that the risk of tearing is greatly reduced.

Finally, the sleeve 3 can be changed easily for example if we want to replace it with a switch or socket. Indeed, in the devices of the prior art, the repeated uninstallation and reinstallation operations, while being tedious operations, also fatigue parts. Indeed, the housing and the sleeve are generally molded plastic parts, and therefore they can lose their elasticity and break, requiring replacement.

According to the device 1 described, a simple sliding of the sleeve 3 allows to install and uninstall the device. The sleeve retains an outer shape regardless of the function provided, whether it is a switch, a power socket, or a CPL socket, so that the function exchange is done simply by the sleeve exchange. In addition, a simple clipping of the sleeve in the housing ensures easy assembly. Disassembly remains easily achievable but with a screwdriver type tool that bears on the two plastic shelves 35 triggering the release of the sleeve. As a result, the CPL connection device complies with the NF C15-100 standard, which states that it is possible to manually connect electrical equipment, but that it must be disassembled only with a tool.

Thus, from a single housing 2, it is possible to easily change the function. INDEX connection device
