  • 9e shows the visible area of the color display. The glass front outside the visible area is colored in the housing color.
  • the cutout 9g serves as an opening for a motion detector.
  • the opening 9f forms the sound outlet opening for the loudspeaker mounted behind it.
  • the perspective view of the upper housing part according to FIG. 10 clarifies the opening 10a in the edge area, which enables external access for “releasing” the snap-fit latching connection 10b.
  • Openings 10c for European or 86mm flush-mounted boxes and American flush-mounted boxes 10d are incorporated on the underside.
  • 10f identifies the spring contact terminal for the electrical connection of the supply lines and consumers.
  • the housing openings for the electrical cables are equipped with a taper 10e for clamping the electrical lines.
  • An LSA terminal 10g is also incorporated in the flush-mounted area.
  • the partition of the sensor area is hollow for better insulation, recognizable by marking 10h
  • Figures 11 to 14 show all side views of the housing, the upper housing part is mounted on the top of a plate of a lower housing part.
  • a pot-shaped bulge is formed on the underside of the plate of the lower housing part.
  • the pot-shaped bulge of the lower housing part has an outer diameter that is smaller than the inner diameter of a standard flush-mounted box.
  • the height of the bulge of the lower housing part is smaller than the height of a standard flush-mounted box.
  • Figure 13 side view from the left, with:
  • FIG. 15 shows the recording position for the light sensor or LED and the camera module.
  • the soldered SMD component 15b on the circuit board forms the permanently installed light sensor.
  • the housing shape 15c optionally allows the angular camera module 15a to be accommodated or a round plastic lens to be accommodated.
  • FIGS. 16 and 17 A further development of the separated sensor area with valve is shown schematically in FIGS. 16 and 17.
  • the numbering in both drawings is identical.
  • the shielding of the sensor area is formed via a longitudinal cutout in the circuit board 16f and via a partition 16c.
  • the separated sensor area has direct contact with the ambient air via the openings in the edge area 16h in the upper housing part 16e.
  • the valve flap 16d completely closes off the separated area from the rest of the control unit. Gravity, which acts in the direction of arrow 16a, keeps the flap closed in the normal state.
  • control device has an increased cooling requirement or there is another reason for ventilation, an air flow is generated in the direction 16b by a fan, and the resulting suppression opens the flap / lever 16d.
  • the opened flap then allows air to flow through the entire housing.
  • the stop point 16g limits the range of motion to such an extent that the center of gravity of the valve flap 16d cannot lie above the axis of rotation and the acting gravity 16a closes the flap again when the fan is switched off.
  • the valve flap 16d can also be designed as a membrane (for example a flexible membrane fixed on one side).
  • FIG. 18 shows the exemplary installation of an expansion module in the device.
  • the main board 18c is screwed to the upper housing part 18a via plastic domes 18b with screws 18e.
  • a spring pin contact is soldered or pressed into the main circuit board as an example. If the pin is soldered, it is soldered from the back.
  • the collar 18j on the spring pin determines the correct position in the main board and at the same time serves as a solder receiving surface.
  • the spring pin head 18i is freely movable vertically and a spring present in the spring pin (detail drawing A) presses the head in the direction of the expansion board 18d.
  • Metallic contact points 18h or metallized THT bores (exemplarily 18f) are present in the expansion board.
  • the bias of the spring of the spring pin creates a secure electrical connection between the two boards. Due to the type of construction, the distance 18k between the boards is almost 0. In the main board, there are milled-out areas below the expansion modules to enable expansion modules equipped on both sides.
  • the invention is not limited to the present embodiments.
