- the actuator and the power supply device which comprise the display means MS, thus depending on the visibility of the actuator and the power supply device, the user is always informed of the charging progress.
- the user is informed when the load takes place according to the second profile or according to the first profile then the second profile. It could be provided that a signal is emitted when the charging takes place according to the first profile and that the emission of the signal stops when the charging takes place according to the second profile.
- the second circuit card 15 is intended to be arranged at a longitudinal end of the actuator perpendicular to the longitudinal axis mounted in the torque support 1 of the actuator, at least partly outside the diameter of the actuator housing.
- the second circuit board 15 is in the form of a printed circuit board having a general half-moon shape configured to fit into the cross section of the torque support 1.
- the charging connector 16 is mounted through the second circuit card 15 which has a cutout 38 opening into a rounded edge of the card 15.
- the connector is oriented radially so that its open end is oriented towards the exterior of the card.
- the second circuit board 15 has through passages (not visible) for the insertion of fixing lugs 34 which are then folded and/or soldered to the opposite face of the second circuit board.
- the second circuit card 15 has two connectors 40 on its opposite face which are connected to the connector and are oriented perpendicular to the plane of the second card, so that their open end is oriented in the longitudinal axis of the actuator.
- This configuration is particularly advantageous because it allows the layer(s) 42 connecting the connector to the first circuit card 13 (FIG. IA) to be plugged into the connector in the axis of the actuator, without being bent.
- the implementation of two smaller connectors allows for easier integration than the implementation of a single large connector.
- the two connectors 40 have a different number of pins which provides a keying function during assembly. It will be understood that a second circuit board 15 comprising a single connector 40 does not depart from the scope of the present invention.
- a cover 39 covers the longitudinal end of the torque support. It has a circular shape with a bottom 39.1 and a rim 39.2. A window 41 is made in the rim 39.2 of the cover 39, giving access to the open end of the charging connector (figure 10).
- This achievement has the advantage of having a torque support whose radial dimensions are limited.
- the second circuit board 15' comprises a part 15.1' in the form of a disk portion corresponding to the general section of the torque support of the actuator and a part 15.2' of substantially rectangular shape projecting from the outer periphery of the disk.
- the dimension d of the part 15.2' in the radial direction is sufficient so that a large part of the body 30 of the charging connector in the radial direction is located mainly outside the diameter of the circular section of the actuator housing.
- the central zone of the 15' card being almost entirely available, it is possible to provide a cutout capable of accommodating different forms of force recovery support and thus make the actuator compatible with a large number of support devices for sunscreen or blackout devices.
- the actuator housing has a circular cross section.
- the torque support may have a cross section on its larger diameter disk-shaped portion, provided with a substantially rectangular projection.
- the hood has a suitable shape. Its side wall has a window for access to the connector.
- the torque support is shaped to surround the second card 15' with its projection.
- the actuator charging connector is a female connector.
- the actuator includes a male charging connector, compatible with a power supply device provided with a female connector.
