Description

Title of the invention: Power supply assembly for a blackout device and blackout device

[0001] The invention relates to the technical field of motorized rolling blackout devices for a bay window, and in particular blackout devices comprising a battery, for example powered by means of a photovoltaic panel.

[0002] The term "blackout element" refers to any rolling device capable of extending in front of an opening so as to provide protection against light and / or temperature (heat and cold) and / or break-ins. Thus, such a blackout element includes, for example, a shutter, a blind, a flexible curtain or an adjustable sunshade.

[0003] Throughout the remainder of this text, the terms "blackout device", "motorized blackout device" or "motorized rolling blackout device" all refer indiscriminately to a motorized rolling blackout device comprising a battery powered by means of a photovoltaic panel.

[0004] Generally, and as can be seen in [Fig. 1], a blackout device 100 comprises a mechanical part, including a housing 101 and a blackout element (not visible). Typically, the blackout element winds and unwinds on a longitudinal axis pivoting relative to the housing, and an actuating part (not visible) allows the blackout element to be set in motion.

[0005] Usually, the box 101 is in the form of a substantially parallelepiped-shaped box and has a front face (not visible) equipped with a photovoltaic panel (not visible), as well as a rear face 102, opposite the front face (not visible), intended to allow the installation of the obscuring device on a support (not visible), for example a wall or a partition or any other support surrounding a bay.

[0006] Generally, the box has a cavity, allowing to receive in particular the occulting element and the actuating part, the actuating part integrating a geared motor.

[0007] It is well known to use blackout devices with a self-powered system, i.e., operating via a battery located in the housing and connected to the geared motor. Such a solution allows the blackout element to be operated without requiring a connection to the conventional electrical network via cables. This absence of wiring simplifies the installation and integration of the blackout device onto the support. It is thus possible to easily install the blackout device, regardless of the chosen location, without being constrained by the existing electrical network.

[0008] In order to allow regular use of the blackout device 100 without having to recharge the battery via a wired connection to the electrical grid, it is known to equip the housing with a photovoltaic cell. Furthermore, the use of renewable solar energy allows the user to limit their electricity consumption.

[0009] Coupling the photovoltaic cell with a battery thus makes it possible to store the energy produced, providing increased autonomy to the shading device. Such storage capacity allows the shading device to operate even in the absence of direct sunlight, making it possible to use it regardless of weather conditions or time of day.

[0010] The implementation of an occulting device 100 with an autonomous power supply has the particular disadvantage that a fault on the battery rendering it inoperative has the consequence of preventing the activating of the occulting element.

[0011] Such a fault may be encountered if the battery is discharged, for example if the shading element is operated many times, and at the same time, a lack of sunlight prevents the battery from recharging.

[0012] Such a defect can also occur in the event of a battery malfunction, for example, if the battery has reached the end of its service life. Since a battery generally has a shorter lifespan than the other components of the shading device 1, the user is highly likely to encounter such a problem.

[0013] To overcome the drawbacks described above, the blackout devices are equipped with a maintenance connection 103, also called a "maintenance socket". This connection 103 allows a plug to be connected to an external source of electrical power to recharge the battery, or to a backup battery, in case the blackout device's battery is out of service.

[0014] Typically, and as can be seen in [Fig. 1], such maintenance connectors are positioned on the rear face 102 of the housing 101 and are oriented downwards to facilitate the connection of a plug (not shown in the figure).

[0015] In general, maintenance connectors take the form of a housing in which connectors and cables are housed, which pass through the rear wall of the enclosure.

[0016] As can be seen in the figures, the connectors known until now protrude from the rear face 102 with too large a bulk, which hinders the fixing of the blackout device 100 on the support.

[0017] The invention aims to address the aforementioned drawbacks.

[0018] A first object is to propose a power supply assembly comprising a connector allowing the connection of an electrical power source.

[0019] A second object is to propose a power supply assembly comprising such a connector, the connector having a reduced footprint compared to prior art connectors.

[0020] A third object is to propose an occulting device equipped with such a power supply assembly.

[0021] In this respect, it is provided firstly, a power supply assembly for a motorized rolling blackout device for a bay window, the power supply assembly comprising a battery intended to be connected to a photovoltaic panel, a casing defining an internal volume and comprising a rear wall having a first notch, an electrical module comprising a first connector, a second connector intended to be connected to the battery, and an intermediate means for electrically connecting the connectors together, the connectors and the intermediate means being intended to be fixed to each other and to the rear wall, the intermediate means comprising a contact surface, the first connector comprising a first stopping surface, the contact surface and the first stopping surface being parallel to each other, and positioned on either side of the rear wall, when the electrical module is fixed to the rear wall,the first connector extending within the first notch.

[0022] Advantageously, the first notch includes a bearing area, the connector comprising a body integrating a first tab, a first stop surface being provided on the first tab, the tab bearing on the bearing area when the module is secured to the rear wall.

[0023] According to one aspect, the rear wall includes a lateral edge comprising a second notch, a second stop surface, extending parallel to the contact surface, the second stop surface and the contact surface are parallel to each other, when the electrical module is fixed to the rear wall, the contact surface and the second stop surface are on either side of the rear wall.

[0024] In some embodiments, the second notch defines a perimeter forming a U.

[0025] Advantageously, when the electrical module is attached to the rear wall, the intermediate means defines a first part, and a second part, the first part and the second part being connected by a first bend so as to form in a longitudinal plane an L shape.

[0026] In one embodiment, a second elbow connecting the second connector to the second part, the second connector extending mainly in a different plane from the main plane of extension of the parts.

[0027] According to one aspect, the rear wall includes an opening, the intermediate means integrating a finger, when the electrical module is attached to the rear wall, the finger is inserted into the opening.

[0028] Advantageously, the intermediate means includes tracks integrated within the material forming the intermediate means.

[0029] Advantageously, the intermediate means defines a conduit comprising electrical cables.

[0030] In one embodiment, the power supply assembly is an extension assembly intended to be connected to the second connector by means of an adapter, the second connector comprising a first snap-on means, the adapter incorporating a second snap-on means capable of cooperating with the first snap-on means.

[0031] Advantageously, the power supply assembly includes a bridge intended to connect to the first connector, the bridge having a first male pluggable portion, the first connector integrating a female pluggable portion complementary to the first pluggable portion, when the first connector is connected to the bridge, the first pluggable portion being inserted into the second pluggable portion with a tight fit so as to remain joined to each other.

[0032] In one embodiment, the first pluggable portion and the second pluggable portion incorporate complementary keying means allowing the first pluggable portion to be inserted into the second pluggable portion in a single position.

[0033] Secondly, a device is provided to conceal a power supply assembly as presented above.

[0034] Other features and advantages of the invention will become more apparent and concrete upon reading the following description of embodiments, given by way of non-limiting example, and made with reference to the accompanying drawings, in which:

[0043] [Fig.9] Fig.9 represents a schematic view of a rear wall,

[0044] [Fig. 10] The [Fig. 10] represents a schematic electrical diagram of a blackout device implementing the power supply assembly.

[0045] Reference is made to [Fig.2], and to [Fig.10] both representing an example of the realization of an occulting device 1, allowing the actuation of an occulting element by means of a geared motor M (visible only on [Fig.10]).

[0046] Typically, the shading device 1 is intended for use with an opening (not shown in the figures), i.e., a skylight in a facade, wall, or roof. Generally, such a skylight is fitted with a translucent or transparent plate, made of glass or thermoplastic.

[0047] In the figures, the blackout element is a roller shutter (not visible in the figures). A roller shutter is generally composed of horizontal metal or plastic slats hinged together so that they can roll up around an axis (not visible in the figures) which is rotated by the geared motor.

[0048] In other embodiments not shown, the blackout element is a flexible fabric designed to attenuate the light radiating from a window. The fabric is generally made of material, but can also be made of a fine polymer mesh, so as to constitute, for example, a mosquito net or a blind. The fabric is designed to roll up around an axis driven in rotation by the geared motor M.

[0049] In other embodiments not shown, the blackout element comprises a plurality of horizontal blades connected to each other by a transmission system, generally wires or chains, so that they can be pivoted and thus synchronously adjust the angle of the blades, in order to control the amount of light entering the bay.

[0050] As can be seen in Figures 2, 3, and 10, the shading device 1 comprises a housing 2 receiving a photovoltaic panel P (visible in [Fig. 10]). Such a photovoltaic panel P makes it possible to convert the received light energy into electrical energy, which is transmitted to the geared motor M via a battery B (visible only on [Fig. 10]).

[0051] Throughout the remainder of this text, an orthogonal XYZ frame of reference is defined with respect to the box 2, comprising three axes perpendicular in pairs, namely:

[0052] - an X axis, coinciding with the general direction of extension of the box 2, defining a longitudinal direction;

[0053] - a Y-axis, defining a horizontal, transverse direction, which with the X-axis defines a horizontal XY plane;

[0054] - a Z-axis, defining a vertical direction, perpendicular to the horizontal XY plane, the YZ axes defining a transverse plane, the XZ axes defining a vertical plane.

[0055] As shown in the figures, the housing 2 advantageously comprises two side walls 3, a front wall 4, a top wall 5 and a rear wall 6, opposite the front wall 4. The walls 3, 4, 5, 6 form a casing, defining an internal volume V. Such an internal volume V allows, in particular, the housing of the shading element, the battery B and the geared motor M.

[0056] Without this being shown in the figures, the geared motor M, the photovoltaic panel P and the battery B are controlled by a control system, in this case integrated into the geared motor M, allowing in particular the management of the interface between the actions of the user, the management of the charge of the battery B and the control of the geared motor M.

[0057] As can be seen in [Fig.2], the blackout device 1 includes a power supply assembly 7 incorporating the housing 2, the battery B and an auxiliary unit 8.

[0058] In the embodiments described, and as seen in [Fig.10], the geared motor M, the photovoltaic panel P, the battery B and the auxiliary unit 8 are connected together by forming an electrical path C. Between such components, the electrical path C is made for example by means of cables, cable bundles or cable harnesses.

[0059] The auxiliary unit 8 allows for the addition of electrical power to the geared motor when the battery B is discharged or defective. More specifically, when the battery B is no longer able to supply electrical power to the geared motor, the user connects an additional battery or a mains cable to the power supply unit 8. Such a connection can be made directly to the battery B if a charger is available, or to the geared motor M for its operation if a backup battery is available.

[0060] As illustrated in the figures, the auxiliary unit 8 advantageously comprises an extension assembly 41, an electrical module 12 and a bridge 40.

[0061] In the embodiment shown, the extension assembly 41 allows the electrical module 12 to be connected to the battery B and / or to the geared motor M.

[0062] In the embodiment shown, bridge 40 acts in particular as a cap to protect the electrical connection to the electrical module 12.

[0063] More specifically, and as can be seen in [Fig. 10], the bridge 40 is equipped with electrical conductors, and allows the electrical path C to be closed. In such a situation, the electrical path C is continuous between the photovoltaic panel P and the battery B. In other words, the bridge 40 acts as a switch allowing the electrical path to be cut off.

[0064] Advantageously, the bridge 40 is arranged between the battery B and the geared motor M. Also, in the presence of the bridge 40, the blackout device 1 is able to function since the electrical path C between the battery B is connected to the geared motor M. In such a situation, in the absence of the bridge 40, the electrical path C is open, the battery B can no longer supply energy, which prevents the battery from discharging before the blackout device 1 is mounted. Unless energy is supplied via the auxiliary unit 8, the geared motor M cannot operate.

[0065] In [Fig.2], the electrical unit 8 is in its operating configuration. In such a configuration, the extension assembly 41, the electrical module 12 and the bridge 40 are mechanically and electrically connected to each other.

[0066] In operating configuration, the extension assembly 41 advantageously extends transversely within the internal volume V. The electrical module 12 is fixed to the rear wall 6, and the bridge 40 is connected to the electrical module 12 and extends mainly in a transverse plane.

[0067] In [Fig. 7], the electrical unit 8 is in its disassembled configuration. In this configuration, the extension assembly 41, the electrical module 12, and the bridge 40 are disconnected. This configuration reduces the size of the auxiliary unit 8 and facilitates its storage and transport before assembly. Furthermore, the fact that the bridge 40 and / or the extension assembly 41 are not connected to the shading device 1 avoids creating the electrical path and discharging the battery B before use.

[0068] In the embodiment shown, the extension assembly 41 includes a plug assembly 51 including a first plug 66 allowing, for example, the connection of the auxiliary unit 8 to the geared motor M and a second plug 67 allowing the connection of the auxiliary unit 8 to the battery B of the blackout device 1.

[0069] Advantageously, the power supply assembly 7 includes an adapter 49 for connecting the electrical module 12 to the extension assembly 41. The plug assembly 51 and the adapter 49 form two end parts of the extension assembly 4L

[0070] In the embodiment shown, the electrical module 12 comprises a first connector 9 and a second connector 10, electrically connected to each other by an intermediate means 11, and mechanically joined together, particularly when the auxiliary unit 8 is in mounted configuration.

[0071] Advantageously, the first connector 9 is intended to be connected to an external power source. The second connector 10 is intended to be connected to battery B, for example via the extension assembly 41.

[0072] In the embodiment shown, the electrical module 12 is a single unit, and the connectors 9 and 10 are all manufactured simultaneously, for example by injection molding. This configuration simplifies the manufacturing of the electrical module 12.

[0073] In embodiments not shown, the electrical module 12 is made by assembling the connectors 9, 10 and the intermediate means 11 previously manufactured separately.

[0074] In the embodiment shown, the electrical module 8 is a single unit, so that the intermediate means 11 and the connectors 9 and 10 are integral from the manufacturing stage. Such an electrical module 8 is economical to produce.

[0075] In embodiments not shown, the electrical module is obtained by assembling and securing the connectors 9, 10 and the intermediate means 11 previously manufactured.

[0076] The electrical module 12 defines a continuous electrical path extending between the first connector 9 and the second connector 10, and passing through the intermediate means 11.

[0077] Advantageously, the intermediate means 11 is in the form of a hollow conduit or channel, allowing the electrical current to be routed from the first connector 9 to the second connector 10.

[0078] According to the embodiment shown, the material is of the thermoplastic type, such a material being insulating, cheap, and lightweight.

[0079] In embodiments not shown, the material used for the intermediate means 11 is a metallic material, which may be the same as that used for the back wall, thus avoiding the use of another die for the manufacture of said intermediate means

[0080] In the illustrated embodiment, the electrical path in the intermediate means 11 takes the form of at least one conductor integrated into the material forming the intermediate means 11.

[0081] In other embodiments not shown, the electrical path within the intermediate means 11 takes the form of at least one cable or a bundle of cables extending within the intermediate means 11.

[0082] As can be seen in [Fig. 2], the front wall 4 advantageously comprises a front edge 13 and the rear wall 6 incorporates a rear edge 14, having respectively a front fold 15 and a rear fold 16. Such folds 15, 16 serve to stiffen the front wall 4 and the rear wall 6, both of which are made from sheet metal. In addition, such folds prevent the edges 13, 14 from being sharp, thus limiting the risk of injury during the manufacture and handling of the enclosure 2, as well as during the mounting of the shading device 1 on a support.

[0083] Advantageously, the front edge 13 and the rear edge 14 are spaced apart, forming a slot 17 for the passage of the shading element. The electrical module 12 and its attachment to the housing 2 are described more specifically with reference to Figures 2 to 8.

[0084] As can be seen in Figures 2 and 3, the electrical module 12 is secured to the rear wall 6 by means of the intermediate means 11. For this purpose, the intermediate means 11 comprises a contact surface 18, advantageously substantially flat.

[0085] The rear wall 6 incorporates a first bearing surface 19 provided outside the box 2, in other words, outside the internal volume V. Inside the box 2, the rear wall 6 includes a second bearing surface 20. The first bearing surface 19 and the second bearing surface 20 are advantageously flat and opposite each other.

[0086] As can be seen in Figures 5 and 8, the first connector 9 includes a first stop surface 21, extending parallel to the contact surface 18. The first stop surface 21 and the contact surface 18 are offset from each other, so as to be able to receive a solid having planes.

[0087] When the electrical module 12 is attached to the rear wall 6, the contact surface 18 and the first stop surface 21 are positioned on either side of the rear wall 6. In other words, the rear wall 6 is sandwiched between the contact surface 18 and the first stop surface 21.

[0088] In such a configuration, the first connector 9 extends at least within a first notch 22 provided on the rear wall 6, the first connector 9 being partially in the internal space V, as can be seen in [Fig.4].

[0089] In this way, it is possible to limit the size of the electrical module 12 to its absolute minimum. Thus, as can be seen in [Fig. 3], the electrical module 12 does not extend transversely beyond the rear fold 16 on the rear side 14. Such an arrangement has the advantage of not creating a protrusion that would be troublesome for the installation of the housing 2 on a support.

[0090] As observed in the figures, the first notch 22, visible in [Fig. 9], is provided on the rear edge 14 of the rear wall. With such a rear edge 14 free, the first connector 9 is accessible to the user, near the slot 17.

[0091] Advantageously, and as shown in [Fig. 6], the second connector 10 incorporates a second retaining surface 23, extending parallel to the contact surface 18. The second retaining surface 23 and the contact surface 18 are offset from each other. Thus, when the electrical module 12 is fixed to the rear wall 6, the contact surface 18 and the second retaining surface 23 are located on opposite sides of the rear wall 6.

[0092] In such a configuration, the second connector 10 extends within a second notch 24 (visible in [Fig.9]) provided on the rear wall 6, the second connector 10 extending in a general transverse direction in the internal space V.

[0093] In this way, it is possible to limit the size of the electrical module 12 to its absolute minimum since the second connector 10 is in the internal space V. As seen in [Fig.3], the electrical module 12 is compact, not extending transversely beyond the rear fold 6 on the rear side 14. Such an arrangement has the advantage of not creating a troublesome protrusion for the installation of the housing 2 on a support.

[0094] As can be seen in particular on [Fig.9], the second notch 24 is provided on a lateral edge 25 of the rear wall 6. Such a location allows the second connector 10 and the extension assembly 41 to be positioned within a pre-existing space to house cables of the geared motor M.

[0095] The first connector 9 is now described in more detail with reference in particular to figures 4, 7 and 8.

[0096] In the embodiment shown, the first connector 9 is located at the end of a first termination 26 of the intermediate means 11.

[0097] The first connector 9 advantageously comprises a body 27 intended to accommodate male or female electrical connection means (not visible in the figures).

[0098] In the embodiment shown, the connection means are female, due to the presence of a recess (not visible) suitable for fitting onto a male pluggable portion 48.

[0099] In other embodiments not shown, the connection means are male, the first connector 9 comprising a protruding part suitable for fitting into a recess provided in the bridge 40.

[0100] Advantageously, the body 27 has a longitudinal dimension greater than the longitudinal dimension of the intermediate means 11, allowing the first connector 9 to integrate a shoulder 28.

[0101] As can be seen in [Fig. 8], the shoulder 28 includes a horizontal stop plane 29. The shoulder 28 comes into contact with a contour 61 (visible in [Fig. 9]) of the first notch 22. Thus, the stop plane 29 acts as a stop against the first notch 22, preventing vertical translation of the electrical module 12 towards the upper wall 5 of the housing 2.

[0102] Such an arrangement facilitates the mounting of the electrical module 12 on the rear wall 6 and limits the volume of the first connector 9. The first connector extends within the first notch, and is partially inserted within the internal volume V of the housing 2.

[0103] Advantageously, the first connector 9 incorporates at least one tab 59 projecting from the body 27, and more particularly from the stop plane 29, forming a tab. Such a tab 59 contains the first stop surface 21, which helps to hold the rear wall 6 between the contact surface 18 and itself, i.e., to "sandwich" the rear wall between the contact surface 18.

[0104] In the embodiment shown, the first connector 9 comprises two shoulders 28 and two tabs 59 arranged symmetrically on either side of the first termination 26, thus allowing a balanced distribution of forces.

[0105] Advantageously, the second connector 10 is located at the end of a second termination 30 of the intermediate means 11.

[0106] In the embodiment shown, the second connector 10 includes a base 31, advantageously with a cross-sectional dimension greater than the dimension of the intermediate means 11. Such a base is intended to protect male or female electrical connection means.

[0107] In the embodiment shown, the connection means are male, taking for example the form of lugs 63, observable on [Fig.7].

[0108] Advantageously, the base 31 incorporates at least one rim 32 comprising the second stop surface 23, intended to come into contact with the wall 9. Such a second stop surface 23 serves as a stop against the second notch 24, preventing any movement of the electrical module 12 towards the upper wall 5 of the box 2.

[0109] In order to facilitate the installation of the electrical module 12, the dimension of the second notch 24 in the longitudinal direction is slightly larger than the longitudinal dimension of the second connector 10. In other words, a longitudinal clearance J is defined between the second notch 24 and the second connector 10, in order to facilitate the mounting of the electrical module 12 on the rear wall 6. The clearance J is apparent in [Fig. 6].

[0110] In the embodiment shown, the second connector 10 comprises two flanges 32, each comprising a second stopping surface 23. The flanges 32 are arranged symmetrically on either side of the second termination 30, ensuring a balanced distribution of forces.

[0111] The intermediate means 11 is now described with reference in particular to figures 7 and 8.

[0112] As can be seen in the figures, the intermediate means 11 advantageously integrates a first part 34 and a second part 35 linked together.

[0113] In the embodiment shown, the first part 34 and the second part 35 are both in a straight line direction.

[0114] In other embodiments not shown, the first part 34 and / or the second part 35 define a curve.

[0115] Advantageously, the first part 34 and the second part 35 are connected to each other by means of a first elbow 36, the first part 34 and the second part 35 defining an angle between them.

[0116] In the embodiment shown, the first part 34 and the second part 35 have an angle of 90° between them, giving the intermediate means 11 an L-shape, which extends in a longitudinal plane when the electrical module 8 is attached to the rear wall 6.

[0117] In embodiments not shown, the intermediate means 11 is rectilinear, the first part 34 and the second part 35 are aligned.

[0118] Such an arrangement allows the terminations 26, 30 to be placed close to the edges 13, 25 of the rear wall 6, thus making the connectors 9, 10 easily accessible. In addition, the overall size of the electrical module 12 is limited and does not extend transversely beyond the rear fold 16.

[0119] Advantageously, the intermediate means 11 includes a second elbow 37 connecting the second connector 10 to the second part 35. The second connector extends mainly in a different plane from that in which the parts 34, 35 and the first elbow 36 extend mainly.

[0120] In the embodiment shown, when the electrical module 8 is attached to the rear wall 6, the first connector 9, parts 34, 35, and the first elbow 36 extend mainly in a longitudinal plane, while the second part extends mainly in a transverse plane. In other words, in such a configuration, the second elbow 37 redirects the electrical path, which extends within the first connector 9 and the intermediate means 11 in a longitudinal plane, to a transverse plane for the second connector 10.

[0121] An example of a rear wall 6 is described more specifically, with reference to [Fig.9]. As described above, such a rear wall 6 advantageously integrates the first notch 22 and the second notch 24.

[0122] In undrawn embodiments, a single notch is provided for the first connector 9, the second connector 10 passing through the rear wall 6 by means of a simple rectangular window, without precise means of attachment.

[0123] In the embodiment shown, the first notch 22 and the second notch 24 each define a U shape, preferably obtained by partial cutting in the sheet metal constituting the rear wall 6. Such a U shape is therefore easy to obtain.

[0124] The notches 22 and 24 allow the insertion and respective fixing of each of the connectors 9 and 10 to the rear wall 6 without the use of additional components such as screws or tools. This facilitates the securing of the electrical module 12 for mounting the shading device 1 onto a support.

[0125] Advantageously, the contour 61 comprises two lateral sections 42 and a stop section 43, perpendicular to the lateral sections 42. The stop section 43 connects the lateral sections 42 to each other.

[0126] In the embodiment shown, the first notch 22 comprises, between the lateral section 42 and the stop section 43, a transverse fraction 64 and a support fraction 65, for example horizontal. The transverse fraction 64 and the support fraction 65 intersect advantageously at a right angle, defining an intermediate zone 44 "in a stepped fashion".

[0127] Preferably, an intermediate zone 44 includes a support zone 45, allowing the support of a tab 59, and more particularly of the first stop surface 21 when the module 12 is secured to the rear wall 6, in other words when the first connector 9 is inserted into the first notch 22.

[0128] Advantageously, the second notch 24 defines a perimeter 60 comprising two lateral portions 46 and a stop portion 47, the stop portion 47 being perpendicular to the lateral sections 46.

[0129] Advantageously, the perimeter 60 defines substantially a U-shape. In the embodiment shown, the stop portion 47 connects the lateral portions 46 to each other at advantageously right angles, in other words. In embodiments not shown, the angles between the stop portion are arbitrary.

[0130] To enable the intermediate means 11 to be secured to the rear wall 6, a finger 58 is advantageously provided projecting from the contact surface 18. The finger 58 is complementary to an opening 62 provided in the rear wall 6.

[0131] Advantageously, the finger 58 includes a retaining means (not visible in the figures). More specifically, when inserted into the opening 62, the finger 58 undergoes a slight elastic deformation causing compression, allowing it to enter the opening 62, and then returns to its initial shape. Thus, when the module electrical module 12 is secured to the rear wall 6, finger 58 is inserted into the opening 62, preventing the electrical module 12 from being pulled out of the housing 2.

[0132] Bridge 40 is now described with particular reference to Figures 2 and 7.

[0133] Advantageously, the bridge 40 is provided with electrical tracks, and as shown [Fig. 10], its insertion or removal from the first connector 9 allows the electrical path C to be formed or respectively cut off. In other words, the bridge 40 acts as a switch.

[0134] Advantageously, the bridge 40 has a first pluggable portion 48 complementary to a second pluggable portion (not visible in the figures) allowing the insertion and securing of the bridge 40 on the first connection means 9. Such an arrangement facilitates the assembly of the electrical module 12 as explained later in this description.

[0135] In the embodiment shown, the first pluggable portion 48 is male and the second pluggable portion is female, but in embodiments not shown, the first pluggable portion 48 may be female and the second pluggable portion male.

[0136] Advantageously, when the first connector 9 is connected to the bridge 40, the first pluggable portion 48 is inserted into the second pluggable portion with a tight fit, i.e., able to withstand a force greater than an unintentional pull-out, such as the gravitational force of a cable connecting an auxiliary battery to the first connector 9.

[0137] In embodiments not shown, the first connector 9 is kept connected to the bridge 40 by means of a snap-fit ​​system.

[0138] Advantageously, the first plug-in portion 48 and the second plug-in portion each incorporate complementary keying means allowing the first plug-in portion (48) to be inserted into the second plug-in portion in a single position. This arrangement aims to facilitate the assembly of the shading device 1 and to maintain the correct polarity of the connectors when connecting the bridge 40 to the first connector 9.

[0139] As seen in figures 2, 3 and 5, the bridge 40 is provided with gripping means enabling the user to grip the bridge 40 with their fingers. In the embodiment, the gripping means is a raised thickness 38, but in other embodiments, the gripping means is a recess.

[0140] The extension assembly 41 is now described with reference in particular to Figures 2 and 7.

[0141] In the embodiment shown, the extension assembly 41 includes an adapter 49, an extension 50 and a plug assembly 51.

[0142] As can be seen in the figures, the adapter 49 incorporates a base 52 from which extends a first pluggable section 53 intended to be inserted into a second pluggable section 54 provided on the second connector 10.

[0143] In the embodiment shown, the first plug-in section 53 is male and the second plug-in section 54 is female, but in embodiments not shown, the first plug-in section 53 may be female and the second plug-in section 54 male.

[0144] Advantageously, the pluggable sections 53, 54 each incorporate additional keying means to facilitate the assembly of the blackout device 1 and to respect the polarities of the connectors during the connection of the adapter 49 with the second connector 10.

[0145] To allow the pluggable sections 53, 54 to be held in position within each other, the second connector 10 incorporates a first snap-on means 56 and the adapter includes a second snap-on means 57. The snap-on means are able to cooperate together, allowing the second connector 10 to be connected, via the adapter 49, to the extension assembly 41. Such positioning is easily achieved without tools.

[0146] An example of a method for mounting the electrical module 12 on the rear wall 6 is now described.

[0147] The user grasps the intermediate means 11 and brings the contact surface 18 closer to the rear wall 6, with the aim of positioning the intermediate means in a configuration such that the first connector is within the first notch 22 between the lateral portions 46 of the housing 2. Simultaneously, the second connector 10 is near the second notch 24.

[0148] The first connector 9 is offset vertically so that each of the tabs 59 fits into the volume V, each coming into contact with the intermediate areas 44.

[0149] The vertical thrust is exerted until the shoulders 28 come into contact with the support fractions 65. At this moment, the finger 58 is opposite the opening 62. Pressure on the intermediate means 11 allows the introduction of the finger 58 into the opening 62.

[0150] With the second connector 10 located opposite the second notch 24, the rim 32 can be positioned against the perimeter 60, so that the second stop surface 23 is in contact with the contact surface 18. The insertion of the second conductor 10 into the second notch 24 is facilitated by the play J.

[0151] Once the electrical module 12 is secured to the rear wall 6, the plug assembly 51 is connected to the battery and the geared motor M, then the adapter 49 is connected to the second connector 10 by snapping it into place.

[0152] The rear wall 6, fitted with the electrical module 12, is then attached to the rest of the box 2, which integrates the internal components, in particular the geared motor, the battery B and the blackout element.

[0153] Advantageously, the bridge 40 is inserted into the first connector 9, unless the battery B is discharged and requires the addition of an external power source, in which case the first connector 9 does not receive the bridge 40.

[0154] The power supply assembly 7 and the blackout device 1 as described above offer several advantages, including:

[0155] - a simple and quick assembly, requiring no special tools, and with a limited learning;

[0156] - a reduced footprint, not exceeding transversely that provided for by the geometry of the rear wall 6, and not hindering the proper mounting of the box 2 on a support;

[0157] - the use of a small number of parts, with simple shapes, manufacturable in series using well-known and economical processes.
