Description

The invention relates to a receptacle for concealed wiring with a recessed receptacle.

To an increasing extent, the USB connector serves as a standard connector for charging the battery of a mobile audio device or communication device, for example, a cellular telephone and an MP3 player, hereinafter referred to as a USB device.

From DE 102009017265 A1, an electrical wiring component with a charger for a mobile phone is known, with the base of the device formed in the form of a device for hidden wiring and mounted on a standard socket for hidden wiring, which has a charger and an electrical connection for an AC voltage network. The electrical component of the wiring has a front cover in the form of a receiving pocket for vertical insertion of a mobile phone. In the bottom region of the inner chamber, created by means of the lid, there is a stand with a connection interface for the contact of the charging and connecting plug socket of the mobile phone. The connection interface can be configured as a Micro-USB interface.

A similar electrical wiring component with a charger for a mobile phone is known from DE 102009021449 A1, with a charging and connecting plug for connecting a mobile phone and a universal holder for storing / securing this mobile phone on the front side of the device base. The charging and connecting plug can be formed as an interface of the Micro-USB standard.

A similar electrical wiring component with a charger for a mobile phone is known from DE 102009037751 A1, moreover, on the front side of the base of the device there is a charging and connecting USB plug for connecting a USB charging and connecting plug of a USB device, and there is a mechanical ON / OFF switch between electrical connection for AC voltage and charger input.

The basis of the invention is the task of improving the socket for concealed wiring with the recess of the socket in such a way that it was possible to electrically connect a mobile audio device or communication device, for example, a cellular telephone or MP3 player.

According to the invention, this problem is solved by means of a socket for concealed wiring, consisting of a central plate, the base of the socket and a decorative frame,

- moreover, the central plate from the front side in its center has a recess of the socket, and in its edge region has a USB connector,

- moreover, on the back side of the Central plate is secured an insulating case of the USB connector, and in the case of the built-in USB-printed circuit board, which is used to connect the USB-connector

- moreover, the USB contacts of the USB circuit board located at the end pass through the insulating casing,

- moreover, a power supply unit connected to the 230 V AC mains side connected to the 230 V AC mains with a printed circuit board of a power supply unit for powering / charging a mobile audio device or a communication device is connected to the base of the socket outlet;

- moreover, the contact device with spring-loaded pins having a housing with spring-loaded pins is mounted at the base of the socket so that the first contacts of the spring-loaded pins come into electrical contact with the USB contacts, and the second contacts of the spring-loaded pins with the conductive strips of the network circuit board power supply unit

- and for this, the insulating body is immersed in the contact chamber formed in the housing of the base of the socket, and in the said contact chamber, the first contacts of the spring pins are accessible and able to come into contact.

The advantages achieved by the invention are, first of all, that by fully integrating the network power supply into the housing of the socket for concealed wiring and introducing on the front side of the USB connector electrically connected to said network power supply, it is possible to insert a USB plug or USB sockets of a USB device, after which the battery of this USB device can be charged. Naturally, to connect an AC voltage of 230 V to the mains, a regular plug with a grounding contact (Schuko plug) for 230 V or a plug with a central grounding socket of an electrical appliance can be simultaneously inserted into the recess of the socket.

The extremely small installation space available between the recess of the central plate of the plug socket and the edge region of the central plate and the base of the plug socket is optimally used for the contact system of the USB connector according to the invention, taking into account “wallpaper compensation”. “Compensation for wallpaper” of at least 2 mm is made possible by means of the spring travel of the spring-loaded pins of the contact device with the spring-loaded pins (“pogo pins” or generally with the placement of a coil spring).

Preferred embodiments of the invention are given in the dependent claims, as well as in the following description.

The invention is explained in more detail below using the embodiments shown in the drawing.

Showing:

In FIG. 1 shows a perspective view of the connection configuration, respectively, the contact system of the USB connector of the receptacle for hidden wiring with a recess of the receptacle. You can see the USB connector 9, the electrical connections of which are in contact with the USB printed circuit board 11, which is integrated in an insulating casing 10 formed of electrically insulating plastic, and the laterally located, preferably gold-plated USB contacts 12 pass through this insulating casing 10 and thus can electrically contact with the first, preferably also gold-plated contacts 31 of the spring-loaded pins of the first side of the housing 30 of the contact device 29 with spring-loaded pins ("pogo pins" or in general with iem spiral spring). USB circuit board 11 contains the necessary structural elements of the USB connector, such as resistors. As the insulating body 10 can also be used heat-shrinkable tube.

On the second side, through the housing 30 of the contact device 29 with the spring pins, the second, preferably gold-plated contacts 32 of the spring pins pass through. The spring pins can make such a large stroke that the tolerances of the structural components of the socket for concealed wiring are evened out on the one hand, and the offset of the central plate of the socket for hidden wiring to the base of the socket, on the other hand, is also compensated, for example, if under a decorative frame wall socket for hidden wiring wallpaper increase the distance from the central plate to the base of the wall socket, also designated as "computer Nation under the wallpaper. "

The USB connector 9 is formed, for example, as a Micro-USB connector or as a USB-A connector.

The location of the insulating body 10 of the USB connector 9 between the support ring of the base of the plug socket (see pos. 15 in Fig. 8) and the recess of the plug socket (see pos. 4 in Fig. 3) is such that under any circumstances electrical isolation is ensured between low voltage of the USB-connector and a support ring, which is in certain conditions when an error occurs at a potential of 230 V.

In FIG. 2 is a perspective view of a rear side of a central plate of a receptacle for concealed wiring. You can see the insulating body 10 of the USB connector fixed to the rear side of the central plate 3 with the USB contacts 12 of the USB circuit board 11 located at the end.

In FIG. 3 is a perspective view of a front side of a receptacle for concealed wiring of a first embodiment. Speaking of the socket 1 for the hidden wiring of the first embodiment, we are talking about the socket with the central grounding pin 19, which passes through the hole 7 in the recess 4 of the Central plate 3 of the socket 1 of the socket 1 for hidden wiring. The USB connector 9 is located on the edge of the recess 4 of the receptacle of the central plate 3. In the bottom region of the recess 4 of the receptacle there are holes 5 for the contact pins of the plug (the plug with the central ground socket) for contacting the pole contacts 17, which are located at the base of the plug socket ( see item 14 in Fig. 6, 7, 8). In addition, in the bottom region of the recess 4 of the receptacle, there is a central screw 8 for securing the center plate 3 on the base of the receptacle. Another fig. 3 shows a decorative frame 34, which complements a plug-in socket for flush-mounted wiring, and a compliant flush-mounted instrument box 36, which is used for installation in a wall.

With the help of decorative frame 34, elegant integration / unification into the program (concept, style) of the wiring components, respectively the program of switches and sockets is possible, as well as a combination with additional devices, for example switches / buttons / dimmers / sockets of this program of switches and receptacles, for example using double decorative frames, triple decorative frames and the like.

In FIG. 4 is a perspective view of a power supply unit for a USB connector. The network power supply 23 (universal charger) is used for power supply / charging of a mobile audio device or communication device and has a circuit board 25 of a network power supply integrated in the base case, which is used for mounting and for electrical connection of electrical / electronic structural components 24, including a transformer, as well as for connecting the primary parties to the power line of 230 V (phase wire and neutral wire of the mains voltage of 230 V AC, as well as ground oestrus) and to provide on the secondary side low voltage contact.

The voltage is removed through the second contacts 32 of the spring-loaded pins of the contact device 29 with spring-loaded pins, which (contacts) are in contact with the corresponding conductive strips of the printed circuit board 25 of the network power supply, and through the first contacts 31 of the spring-loaded pins of the contact device 29 with spring-loaded pins, which (contacts) with a fully mounted socket for hidden wiring, they are pressed against the USB contacts 12 passing through the insulating body 10 of the USB connector. In this case, the contact force necessary for electrical contact is transmitted from the spring-loaded pins of the contact device 29 with the spring-loaded pins. The bottom plate 26 of the base body forms the end of the base body of the receptacle located on the rear side.

Spring-loaded pogo pins respectively or the placement of a coil spring simplify the manufacture of the device, since they should not be soldered, and thereby manipulation of the soldering line with the upper parts is prevented on the circuit board 25 of the power supply, as would be necessary in the implementation with contact strips. The spring pins spring on both sides relative to the first and second ends of the housing 30 with spring pins, are simply inserted into the base housing and then secured to the circuit board 25 of the mains power supply in the base housing.

When completing the installation of the socket outlet for hidden wiring by an electrician, that is, fixing the central plate 3 on the base of the socket socket mounted in the fixture box of the hidden mounting box, the proposed solution is also preferable, since, for example, there is no danger that the contacting structural elements can be deformed in this case as would happen when using long contact strips for contacting.

In FIG. 5 is a perspective view of a front side of a receptacle for concealed wiring of a second embodiment. Speaking of the socket 1 for hidden wiring of the second embodiment, we are talking about the socket (socket with a grounding contact) with grounding jumpers 18, which pass through the holes 6 in the recess 4 of the Central plate 3 of the socket 3 of the socket 1 for hidden wiring and consist of metal well-conducting electricity. The USB connector 9 is located at the edge (in the corner on the front side) of the recess 4 of the receptacle of the central plate 3. In the bottom region of the recess 4 of the receptacle there are holes 5 for the contact pins of the plug (in this case, the plug with the ground contact) for contacting pole contacts 17, which are located in the base 14 of the socket. In addition, in the bottom region of the recess 4 of the receptacle, there is a central screw 8 for securing the center plate 3 on the base of the receptacle. Another fig. 5 shows again a decorative frame 34, which complements the plug-in socket for flush-mounted wiring, and a flush-mounted instrument box 36, which serves for installation in a wall.

In FIG. 6 is a perspective view of the front side of the receptacle for concealed wiring with the decorative frame removed. You can see the base 14 of the receptacle with a support ring 15 and spacers 20 for mounting in the instrument box 36 flush mounting. On the basis of the 14th socket, the central plate 3 of the socket 1 is fixed for concealed wiring with a USB connector 9 located on the edge of the recess 4 of the socket. The base portion 14 of the plug socket is formed by a special contact chamber 28, in which the first contacts 31 of the spring-loaded pins of the contact device 29 with the spring-loaded pins are accessible and come into contact, and the insulating case 10 of the USB connector 9, including the USB contacts 12, is included. Not shown preferably formed in the form of "screwless connecting terminals" fasteners for wires for the phase wire, neutral wire and ground wire, which are provided in the clamping chambers housing base.

In FIG. 7 is a perspective view of a rear side of a receptacle for concealed wiring with the decorative frame removed. You can see the base 14 of the socket with the bottom plate 26 of the base body, a special contact chamber 28 and spacers 20. The bottom plate 26 is fixed to the shell of the body of the base 14 of the socket through the latches 27 of the bottom plate. In addition, FIG. 7 shows a portion of an insulating body 10 secured to a central plate 3 of a receptacle for concealed wiring.
