Definitions

  • the invention relates to a socket with increased personal protection with a central piece surrounded by a design frame and a base part fixed to a support ring for connecting a first connection for an outer conductor and a second connection for a neutral conductor, which can be connected to the power supply network, wherein a power supply unit can be fixed to the base part, which on the one hand comes into operative contact with the base part and on the other hand is provided for the electrical connection of at least one electrical functional module, wherein the power supply unit has at least one connection socket for connecting the at least one electrical functional module, into which connection socket a plug connector is inserted in a contacting manner, which central piece has openings for the two connections.
  • the invention further relates to a method for the switchable operation of such a socket.
  • Such sockets are generally designed to create an easily separable electrical connection to a consumer via a suitably designed plug and, if necessary, an electrical cable connected to it.
  • Such electrical safety sockets are often equipped with a personal or contact protection device.
  • the increased personal or contact protection is usually achieved by using a locking element, which can be designed as a sliding piece, a rotating piece, etc. can.
  • a locking element which usually interacts with a spring means, automatically shields the live contact parts of the electrical plug device or mechanically locks the two plug openings as soon as the plug is pulled out of the safety socket or plug device.
  • Such an electrical safety socket is protected by the EN 10 2017 102 548 B3
  • Such an electrical safety socket has a base part equipped with an earthing bracket and is intended for connecting a plug with corresponding plug pins and earth contacts.
  • the base part has the contact parts necessary for contacting the plug pins and earth contacts as well as the contact parts required for connecting the electrical cables, whereby the base part is equipped with a carrier and a socket central piece intended to accommodate the plug to be connected.
  • a contact protection device is provided which automatically blocks the plug openings intended for the insertion of the two plug pins by means of a locking element when it assumes its locking position and only releases them when the two plug pins of the plug are inserted into the plug openings at the same time. Even with such a design of a contact protection device, a high level of protection against the The introduction of foreign objects is achieved or contact with electrical contact parts by foreign objects is effectively prevented.
  • WO 2017 / 205 252 A1 discloses a socket that can release a flow of energy by inserting an earthing pin of a corresponding plug.
  • a sensor is activated when it is contacted by an earthing pin, whereby neither an explicit detection of the insertion depth nor of two openings that correspond to the outer or neutral conductor is carried out simultaneously.
  • EP 2 751 883 B1 shows a USB socket with a circuit board that is intended to enable an electrical connection of an MP3 player or a mobile device.
  • EP 2 751 883 B1 does not address personal protection or safety-related aspects. Detection of the insertion depth is not disclosed.
  • EP 1 856 773 B1 discloses a socket with switching elements that are actuated by plug pins that are inserted and are connected to a circuit board, wherein the switching elements are insulated from the socket. An insertion depth detection that would provide sufficient personal protection is not disclosed.
  • WO 2009 / 140 171 A2 shows a socket with a motion sensor that detects the movement of a plug pin in the opening of a socket.
  • the WO 2009 / 140 171 A2 - The object in question has a removal detector which is connected to the motion sensor to trigger further actions in response to the movement to avoid an arc. This is done in WO 2009 / 140 171 A2 no insertion depth detection, but rather a movement and removal detection of a plug pin, which would contribute to personal protection.
  • the invention is therefore based on the object of creating a socket with increased personal protection, in particular when inserting foreign objects into the plug openings in the central piece provided for the insertion of the two plug pins.
  • the core idea of the invention is that the socket according to the invention is able to detect the insertion depth of a plug pin inserted into the openings of the central piece using a sensor. Only when the socket's evaluation unit detects a permissible detected insertion depth of a plug pin is the switchable relay to which the socket is connected switched so that the openings of the two connections (neutral conductor and outer conductor) of the socket are live. The evaluation is ultimately based on a comparison of the detected insertion depth with a permissible range of insertion depth.
  • the socket according to the invention with increased personal protection has a central piece surrounded by a design frame and a base part fixed to a support ring for connecting a first connection for an external conductor and a second connection for a neutral conductor, which can be connected to the power supply network, wherein a voltage supply unit can be fixed to the base part.
  • the power supply unit is on the one hand in contact with the base part and on the other hand is intended for the electrical connection of at least one electrical functional module.
  • a functional module can be, for example, a lighting device or one or more USB ports, which are integrated flush with the design frame in the central piece, which has openings for the two ports.

  • such a device according to the invention also has a circuit board adjacent to the central piece, having an electrical/electronic functional component and insertable into the central piece (creates additional installation space for electrical components).
  • the circuit board comprises a second sensor for detecting the insertion depth. This further improves the detection of the insertion depth in terms of its reliability. Ultimately, in order to overcome such a security level, a person would have to insert two foreign objects into the openings of the socket at the same time, which would lead to a correct insertion depth as part of the evaluation by the evaluation unit.
  • the at least one sensor is designed as a linear potentiometer, so that a gradual detection of the insertion depth is also possible. This allows a more detailed analysis of the insertion depth by the evaluation unit, up to a sub-millimeter-precise detection of the insertion depth.
  • the socket includes a transmitter for transmitting the detected insertion depth or a corresponding signal to a terminal device, in particular a mobile terminal device.
  • a transmitter for transmitting the detected insertion depth or a corresponding signal to a terminal device, in particular a mobile terminal device. This can, for example, send warnings to a parent operating the terminal device if a child makes unwanted use of the socket.
  • the transmitter is a radio transmitter arranged on the circuit board, in particular a Bluetooth transmitter, a Zigbee transmitter or a WLAN transmitter.
  • the relay is arranged in a socket, in particular in the base part. This makes it easy to ensure that the socket is only live when this is desired, i.e. when the correct insertion depth has been detected.

  • the socket according to the invention is connected to a relay in the series-mounted device in the sub-distribution. This allows that in the case of By detecting certain acceleration patterns or positions, entire circuits, such as socket circuits within a room, can be switched off without interrupting the lighting circuit. This has the advantage of protecting the people concerned without them standing in the dark and possibly injuring themselves in an accident.
  • a flexible circuit board section extends from the circuit board and has the connector, which can be spread out for mounting the socket, can be deflected out of the plane of the circuit board.

  • the flexible circuit board section provides additional installation space without affecting the installation depth and the assembly effort.
  • this embodiment of the invention is a particularly space-saving and easy-to-manufacture embodiment that allows different electronic components to be accommodated on different circuit boards in a space-saving manner.
  • the socket has a lighting device integrated into the central piece, which is designed to emit a corresponding optical signal when a permissible insertion depth is detected. This ensures that the user can immediately see whether a plug has been inserted correctly.
  • actuation of the socket means in particular inserting or removing objects into the openings of the central piece, in particular inserting or removing a plug.
  • Such a method according to the invention ensures that a regularly voltage-free state is only required for the operation of the electrical/electronic socket according to the invention.
  • the evaluation of whether the actuation is correct is carried out in an evaluation unit in which certain insertion depths (discrete or gradual ranges) are stored, whereby a comparison is made between the recorded insertion depths and the stored insertion depths.
  • the evaluation of the evaluation unit includes a verification that the insertion depth detected by the at least one sensor is constant over a period of time, for example in the range of 200 ms to 2000 ms, and only in this case is the relay (R) switched on.
