Title of the invention: Electrical wiring accessory to an electrical power supply network of an electromechanical actuator for a blackout device and associated blackout device

[0001] The present invention relates to an electrical wiring accessory, to an electrical power supply network, of an electromechanical actuator for a concealment device. The electrical wiring accessory is provided with a first electrical socket adapted to electrically connect with an electrical plug of an electrical power cable and a second electrical socket adapted to electrically connect with an electrical connector belonging to an electromechanical actuator, while the electrical plug of the electrical power cable is adapted to electrically connect directly with another electrical connector belonging to another electromechanical actuator, in other words without electrical connection to the electrical wiring accessory.

[0002] The present invention also relates to a screening device comprising a screen driven in movement by an electromechanical actuator, an electrical power cable connected to an electrical power network, as well as an electrical wiring accessory, as mentioned above.

[0003] Generally, the present invention relates to the field of occultation devices comprising a motorized drive device moving a screen between at least a first position and at least a second position.

[0004] A motorized drive device comprises an electromechanical actuator of a movable closing, concealing or sun protection element such as a shutter, a door, a grille, a blind or any other equivalent material, hereinafter called a screen.

[0005] Electromechanical actuators for a concealment device are already known, each having a separate electrical connector.

[0006] Thus, the electrical connector of each of the electromechanical actuators is configured to receive an electrical plug adapted from an electrical power supply cable, so as to electrically connect the electromechanical actuator to an electrical power supply network.

[0007] In this way, when an installer wishes to replace the electromechanical actuator of a concealment device, for example in the event of a breakdown of the electromechanical actuator, the installer can only carry out the replacement with an electromechanical actuator having an identical electrical connector, so as not to have to replace the electrical power supply cable of the connected concealment device electrically to the power supply network, so as to minimize the time and cost of intervention and to guarantee the safety of the installer, who may not be electrically qualified.

[0008] Consequently, the installer cannot propose replacing the existing electromechanical actuator in the occultation device with another electromechanical actuator having a different electrical connector, while keeping the electrical power supply cable of the occultation device electrically connected to the electrical power supply network, in particular for another electromechanical actuator having better performance.

[0009] The present invention aims to solve the aforementioned drawbacks and to propose an electrical wiring accessory, to an electrical power supply network, of an electromechanical actuator for a concealment device, as well as a concealment device comprising such an electrical wiring accessory, making it possible to simply replace the electromechanical actuator with another electromechanical actuator having a different electrical connector, while retaining an electrical power supply cable of the concealment device electrically connected to the electrical power supply network, guaranteeing the safety of an installer, who does not have to be electrically qualified, and minimizing the time and cost of intervention of the installer.

[0010] In this regard, the present invention aims, according to a first aspect, at an electrical wiring accessory, to an electrical power supply network, of a second electromechanical actuator for a concealment device, the electrical power supply network being electrically connected to an electrical power cable, the electrical power cable comprising an electrical plug, the electrical plug being configured to plug directly into a first electrical connector of a first electromechanical actuator, without being electrically connected to the electrical wiring accessory, the second electromechanical actuator comprising a second electrical connector, the second electrical connector being different from the first electrical connector.

[0018] Furthermore, such an electrical wiring accessory makes it possible to simplify and secure after-sales service, since the second electromechanical actuator can be mounted in place of the first electromechanical actuator installed, while maintaining an electrical installation present at the level of the occultation device, in other words without modification of this electrical installation, except adding the electrical wiring accessory, and while avoiding an electrical connection error.

[0019] Such an electrical wiring accessory thus makes it possible to reduce the intervention time of an installer and to avoid having to intervene on the electrical supply network during the intervention by the installer, the latter only having to electrically disconnect the first electrical connector of the first electromechanical actuator from the electrical plug of the electrical supply cable of the occultation device, to replace the first electromechanical actuator with the second electromechanical actuator and, on the one hand, to electrically connect the second electrical connector of the second electromechanical actuator with the second electrical socket of the electrical wiring accessory and, on the other hand, to electrically connect the first electrical socket of the electrical wiring accessory with the electrical plug of the electrical supply cable of the occultation device.

The torque support 21 advantageously makes it possible to take up, in addition, forces exerted by the winding tube 4, in particular the weight of the winding tube 4, of the electromechanical actuator 11a, 11b and of the screen 2, and to ensure the take-up of these forces by the structure of the building.

In such a case, the crown 30 can be free to rotate, on the one hand, around the torque support 21 and, on the other hand, around the casing 17 of the electromechanical actuator 11a, 11b.

[0132] Advantageously, the torque support 21 supports, in other words is configured to support, at least a portion of the control unit 15, in particular in the assembled configuration of the electromechanical actuator 11a, 11b.

[0133] Here and as illustrated in [Fig.3], the control unit 15 is thus arranged, in other words integrated, inside the casing 17 of the electromechanical actuator 11a, 11b.

[0134] As a variant, not shown, the control unit 15 is arranged outside the casing 17 of the electromechanical actuator 11a, 11b and, in particular, mounted on the box 9 or in the torque support 21.

[0144] Advantageously, the output shaft 20 of the electromechanical actuator 11a, 11b is configured to drive in rotation a connecting element 22, as illustrated in [Fig.3], connected to the winding tube 4. The connecting element 22 is produced in the form of a wheel.

[0145] When the electromechanical actuator 11a, 11b is put into operation, the electric motor 16 and the reducer 19 drive the output shaft 20 in rotation. In addition, the output shaft 20 of the electromechanical actuator 11a, 11b drives the winding tube 4 in rotation via the connecting element 22.

[0154] Thus, the toothing of the crown 30 is configured to drive in rotation, in other words drives in rotation, the pinion, so as to count the number of turns of the winding tube 4.

[0155] In this case, the teeth of the crown 30 and the pinion form the counting device.

[0156] The counting device also makes it possible to determine the direction of rotation of the winding tube 4 and / or to manage the end-of-travel positions of the screen 2.

[0157] The type of counting device is not limiting and may be different, in particular of the optical type, for example an encoder equipped with one or more optical sensors, or of the time type.

[0158] We will now describe, with reference to Figures 4 to 7, an electrical wiring accessory 24 of the second electromechanical actuator 11b, illustrated in Figures 4 and 5, to the electrical power supply network 25, this electrical wiring accessory 24 being in accordance with an embodiment of the invention.

[0159] The occulting device 3 comprises the electrical wiring accessory 24.

[0160] The electrical wiring accessory 24 includes an adaptor power supply cable 26, as shown in Figures 4-6, a first electrical outlet 32, as shown in Figures 4-7, and a second electrical outlet 33, as shown in Figures 5 and 6.

[0161] The adaptive power supply cable 26 comprises a first end 26a and a second end 26b. The second end 26b is opposite the first end 26a.

[0162] Here, the voltage of the electrical supply network 25 is, preferably, alternating, in particular low frequency, which can be, for example, of the order of 50 Hertz or 60 Hertz. The voltage value of the power supply network 25 may be, for example, of the order of 230 volts or 110 volts. In this case, the power supply network 25 may be a so-called "mains" network.

[0163] Alternatively, the voltage of the electrical power supply network 25 may be continuous and called “very low voltage”. The value of the voltage of the electrical power supply network 25 may be less than or equal to 120 volts and, more particularly, less than or equal to 50 volts. The value of the voltage of the electrical power supply network 52 may be, for example, of the order of 12 volts, 24 volts or 48 volts. By way of non-limiting example, the electrical power supply network 25 may be a so-called “PoE” network (acronym for the English term Power over Ethernet).

[0164] The electrical power cable 18 includes an electrical plug 37, as illustrated in Figures 3, 4 and 5.

[0165] The first electrical socket 32 ​​is arranged at the first end 26a of the adapter electrical power cable 26. The first electrical socket 32 ​​is configured to plug, in other words is plugged, with the electrical plug 37 of the electrical power cable 18.

[0166] The electrical plug 37 of the electrical power supply cable 18 is further configured to plug, i.e. is plugged, directly with the first electrical connector 38a of the first electromechanical actuator 11a, without being electrically connected to the electrical wiring accessory 24, as illustrated in [Fig.3].

[0167] The second electrical socket 33 is arranged at the second end 26b of the adapting power supply cable 26. The second electrical socket 33 is configured to plug, i.e. is plugged, with the second electrical connector 38b of the second electromechanical actuator 11b, as illustrated in [Fig. 4]. The second electrical socket 33 is different from the electrical plug 37 of the power supply cable 18, since the second electrical connector 38b of the second electromechanical actuator 11b is different from the first electrical connector 38a of the first electromechanical actuator 11a.

[0168] Thus, the electrical wiring accessory 24 makes it possible to simply replace the first electromechanical actuator 11a with the second electromechanical actuator 11b, having the second electrical connector 38b, different from the first electrical connector 38a, the second electromechanical actuator 11b being associated with the electrical wiring accessory 24, while retaining the electrical power supply cable 18 of the occultation device 3 electrically connected to the electrical power supply network 25, guaranteeing the safety of an installer, who does not have to be electrically qualified, and minimizing the time and cost of intervention of the installer.

[0169] In this way, the second electromechanical actuator 11b is electrically connected to the power supply network 25 via the accessory of electrical wiring 24, on the one hand, by electrically connecting the second electrical connector 38b of the second electromechanical actuator 11b with the second electrical socket 33 of the electrical wiring accessory 24 and, on the other hand, by electrically connecting the first electrical socket 32 ​​of the electrical wiring accessory 24 with the electrical plug 37 of the electrical power supply cable 18 of the occulting device 3, as illustrated in [Fig. 4]. This differs from the case shown in [Fig. 3] where the first electromechanical actuator 11a is electrically connected to the electrical power supply network 25 directly by electrically connecting the first electrical connector 38a of the first electromechanical actuator 11a with the electrical plug 37 of the electrical power supply cable 18 of the occulting device 3, in other words without electrical connection to the electrical wiring accessory 24.

[0170] Therefore, the electrical wiring accessory 24 is provided with the first electrical socket 32 ​​adapted to electrically connect with the electrical plug 37 of the electrical power cable 18 and this electrical wiring accessory 24 is provided with the second electrical socket 33 adapted to electrically connect with the second electrical connector 38b belonging to the second electromechanical actuator 11b, while the electrical plug 37 of the electrical power cable 18 is adapted to electrically connect directly with the first electrical connector 38a belonging to the first electromechanical actuator 11a, in other words without electrical connection to the electrical wiring accessory 24.

[0171] Furthermore, this electrical wiring accessory 24 makes it possible to simplify and secure after-sales service, since the second electromechanical actuator 11b can be mounted in place of the first electromechanical actuator 11a installed, while maintaining an electrical installation present at the level of the occultation device 3, in other words without modification of this electrical installation, except for the addition of the electrical wiring accessory 24, and while avoiding an electrical connection error.

[0172] This electrical wiring accessory 24 thus makes it possible to reduce the intervention time of an installer and not to have to intervene on the electrical supply network 25 during the intervention by the installer, the latter only having to electrically disconnect the first electrical connector 38a of the first electromechanical actuator 11a with respect to the electrical plug 37 of the electrical supply cable 18 of the occultation device 3, to replace the first electromechanical actuator 11a with the second electromechanical actuator 11b and, on the one hand, to electrically connect the second electrical connector 38b of the second electromechanical actuator 11b with the second electrical socket 33 of the electrical wiring accessory 24 and, on the other hand, to electrically connect the first electrical socket 32 ​​of the electrical wiring accessory 24 with the plug electrical 37 of the electrical power cable 18 of the occultation device 3.

[0184] Advantageously, the first electrical socket 32 ​​further comprises a device 44 for holding the adapting electrical power supply cable 26 in position. The device 44 for holding the adapter in position can also be called a cable clamp.

[0185] Advantageously, the position holding device 44 comprises a first fixed part 44a, in particular relative to the body 32a, and a second removable part 44b, as illustrated in [Fig.7].

Furthermore, the second removable part 44b is fixed, in other words is configured to be fixed, to the body 32a, by means of second fixing elements 45a, 45b, as illustrated in [Fig.7].

[0186] Advantageously, the second fixing elements 45a, 45b are elastic snap-fastening fixing elements.

[0190] In this way, the retaining element(s) 49 and the notch(s) 50 make it possible to prevent the second removable part 44b from sliding relative to the first fixed part 44a.

[0191] Here and in a non-limiting manner, the second removable part 44b comprises two retaining elements 49, only one of which is visible in [Fig.7]. In addition, the first fixed part 44a comprises two notches 50.
