It is a USB port 9 to recognize its electrical connections a USB circuit board 11 contacting, which in an insulating housing formed from an electrically insulating plastic 10 integrated, with front-side, preferably gold-plated USB contacts 12 this insulating housing 10 break through and so with first, preferably also gold-plated spring pin contacts 31 of spring pins of a first side of a spring pin housing 30 a spring pin contact device 29 ("Pogo Pins" or generally spiral spring arrangement) can contact electrically. The USB circuit board 11 picks up required components of the USB port, such as B. resistors. As insulating housing 10 a shrink tube can also be used.

The spring pin housing 30 the spring pin contact device 29 is on a second side of second, preferably gold-plated spring pin contacts 32 the spring pins are broken. The spring pins can perform such a large stroke, that on the one hand tolerances of the components of the flush-mounted socket are compensated and on the other hand, an offset of the central pane of the flush-mounted socket is compensated for socket base, for example, in the case that wallpaper under the cover of the concealed Socket to increase the distance between the central plate to the socket base - often referred to as "wallpaper compensation".

The USB port 9 is designed, for example, as a micro-USB port or as a USB-A port.

The arrangement of the insulating housing 10 of the USB port 9 between the support ring of a socket base - see paragraph 15 in 8th - and the socket - see paragraph 4 in 3 - Is such that the electrical insulation between the extra-low voltage of the USB port and possibly lying in case of failure of a potential lying at a potential of 230 V support ring is guaranteed under all circumstances.

In 2 is a perspective view of the back of a central pane of the flush-mounted outlet shown. It's at the back of the central disk 3 attached insulating housing 10 of the USB connection with the frontal USB contacts 12 the USB circuit board 11 to recognize.

In 3 is a perspective view of the front of the flush-mounted socket of the first embodiment shown. In this flush-mounted socket 1 first embodiment is a socket with a Mittelerdstift 19 which has an opening 7 in the socket pot 4 the central disk 3 the flush-mounted socket 1 breaks through. The USB port 9 is the edge of the socket pot 4 the central disk 3 arranged. In the bottom area of the socket pot 4 there are openings 5 for connector pins of a connector (male connector with female connector) for contacting polar contacts 17 , which in the socket socket - see number 14 in the 6 . 7 . 8th - are arranged. In the bottom area of the socket pot 4 is also a central screw 8th for fixing the central disk 3 arranged on the socket socket. 3 further shows a the flush-mounted outlet complete cover frame 34 and a wall-mounted standard-compliant flush-mounted appliance box 36 ,
