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, with the base part a power supply unit can be fixed, which on the one hand comes into operative connection with the base part in a contact-making manner and which on the other hand is provided for the electrical connection of at least one electrical functional assembly, wherein the power supply unit has at least one connection socket for connecting the at least one electrical functional assembly, in which connection socket a plug connector is inserted with contact is, which central piece has openings for the two connections.
  • the invention also relates to a method for the switchable operation of such a socket.
  • Sockets of this type which are often designed as electrical safety sockets, are generally intended to produce an easily separable electrically conductive connection to a consumer via an appropriately designed plug and, if necessary, an electrical line connected to it.
  • Such electrical protective contact sockets are often provided with a personal or contact protection device.
  • the increased personal protection or contact protection is conventionally realized through the use of a blocking element, which can be designed, for example, as a sliding piece, a rotating piece and so on can.
  • a blocking element which regularly interacts with a spring means, automatically shields the live contact parts of the electrical plug device or mechanically blocks the two plug openings as soon as the plug has been pulled out of the protective contact socket or plug device.
  • Such an electrical safety socket is through the DE 10 2017 102 548 B3 known.
  • Such an electrical safety socket has a base part equipped with a grounding bracket and is provided for the connection of a plug having corresponding plug pins and grounding contacts.
  • the base part has the contact parts required for contacting the plug pins and earth contacts and for connecting the electrical cable, the base part being equipped with a support and a socket center piece provided for receiving the plug to be connected.
  • a contact protection device is provided which automatically blocks the plug openings provided for the insertion of the two plug pins by means of a blocking element when its blocking position is assumed and only releases it when the two plug pins of the plug are inserted into the plug openings at the same time.
  • Such a design of a contact protection device already provides a high level of protection against Introduction of foreign objects achieved, or touching of electrical contact parts by foreign objects, effectively prevented.
  • 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 center piece provided for inserting the two plug pins.
  • a socket the base part of a printed circuit board comprising a sensor for detecting the insertion depth of plug pins to be inserted into the two openings, the socket having an evaluation unit which is suitable for evaluating whether the detected insertion depth is correct, and which Socket is connected to a switchable relay, which relay can be switched depending on the detection of the insertion depth or the evaluation.
  • 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 center piece using a sensor.
  • the switchable relay to which the socket is connected is switched in such a way that the openings of the two connections (neutral conductor and outer conductor) of the socket are live only when the socket's evaluation unit detects a permissible detected insertion depth of a plug pin.
  • 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 outer conductor and a second connection for a neutral conductor, which can be connected to the power supply network, with a power supply unit on the base part is definable.
  • the power supply unit comes into working contact with the base part on the one hand and is provided on the other hand for the electrical connection of at least one electrical functional assembly.
  • a functional module can be, for example, a lighting device or one or more USB connections that are flush with the design frame and are integrated into the center piece that has openings for the two connections.
  • the voltage supply unit has at least one connection socket, into which connection socket a plug connector is inserted in a contacting manner.
  • such a device has a printed circuit board in the base part, which has at least one sensor for detecting the insertion depth of plug pins to be inserted into the openings of the center piece.
  • such a device according to the invention also has a printed circuit board adjoining the central piece, which has electrical/electronic functional components and can be inserted into the central piece (creates additional installation space for electrical components).
  • the printed circuit board includes a second sensor for detecting the insertion depth. This further improves the detection of the insertion depth in terms of its reliability. Finally, 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 lead to a correct insertion depth within the framework of the evaluation by the evaluation unit.
  • the at least one sensor is designed as one or two short-stroke pushbuttons which are mechanically actuated by the plug pins to be inserted. In a particularly simple, cost-effective and robust manner, this allows the evaluation unit to perform a discrete evaluation as to whether or not the correct insertion depth has been reached.
  • the at least one sensor is designed as a linear potentiometer, so that a gradual detection of the insertion depth is also made possible. This allows a more detailed analysis of the insertion depth by the evaluation unit, up to sub-millimetre-precise detection of the insertion depth.
  • the socket includes a transmitter for transmitting the detected insertion depth or a signal corresponding thereto to a terminal device, in particular a mobile terminal device.
  • a terminal device in particular a mobile terminal device.
  • the transmitter is on the printed circuit board arranged radio transmitter, 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 possible to ensure in a simple manner that the socket is only live when this is desired, ie: a proper insertion depth has been detected.
  • the relay is arranged in an actuator connected to the socket.
  • the socket according to the invention is connected to a relay in the rail-mounted device in the sub-distribution board. If certain acceleration patterns or positions are detected, this allows entire circuits, for example socket circuits within a room, to be switched off without interrupting the lighting circuit. In this way it is achieved in an advantageous manner that the persons concerned are protected without them standing in the dark and possibly being injured by accidents.
  • a flexible printed circuit board section which has the plug connector and can be spread apart for mounting the socket outlet, can be deflected out of the plane of the printed circuit board and extends from the printed circuit board.
  • This flexible printed circuit board section is provided with a receptacle for a receptacle section, which extends in the direction of the voltage supply unit, of a housing part connected to the printed circuit board for the electrical connection of the connector of the printed circuit board is joined to the connection socket of the power supply unit. It is particularly advantageous in this configuration that the flexible printed circuit board section makes additional installation space available without impairing the installation depth and the assembly effort.
  • this embodiment of the invention is a particularly space-saving embodiment that is easy to produce and allows different electronic components to be accommodated on different printed circuit boards in a space-saving manner.
  • the socket has an illumination device which is integrated into the center piece and is designed to emit a corresponding optical signal if a permissible insertion depth is detected.
  • actuation of the socket means, in particular, inserting or removing objects into the openings of the center piece, in particular plugging in or pulling out a plug.
  • Such a method according to the invention ensures that a regularly de-energized state is maintained only for the operation of the electrical/electronic socket outlet according to the invention.
  • the evaluation as to whether the actuation is correct can be carried out, for example, in an evaluation unit in which specific insertion depths (discrete or gradual areas) are stored, with the detected insertion depths being compared with 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 from 200 ms to 2000 ms, and only in this case the relay (R) is switched on. This ensures in a simple way that usually not static but dynamic tests, the built-in personal protection are doomed to failure.
  • the reliability of personal protection is improved even further in that the detected insertion depth is compared with one another by the sensors in the evaluation unit and only if the deviation of the two insertion depths is a specifiable one falls below the relay (R) is switched on.
  • the socket outlet 1 in addition to a design frame 2, the socket outlet 1 according to the invention shown in perspective in an exploded view comprises an attachment A and an insert E.
  • the attachment A comprises a central piece 3, a number of electrical/electronic functional components (in particular a radio transmitter and/or an LED lighting device 5 and/or or a printed circuit board LA which can be inserted into the central piece 3 and has evaluation electronics, a housing part GF which is connected to the associated recess in the printed circuit board LA, for example by means of snap-locking.
  • figure 1 shows, preferably from the printed circuit board LA, a flexible printed circuit board section F that can be spread out from the plane of the printed circuit board LA and has a connector 6 for mounting the socket outlet 1 according to the invention.
  • This flexible printed circuit board section F is joined to a receptacle of a receiving section, which extends in the direction of the voltage supply unit S, of the housing part GF connected to the printed circuit board LA.
  • the flexible printed circuit board section F offers the advantage that electrical/electronic functional components can be connected to the printed circuit board LA without loss of installation space. This is advantageously accompanied by a particularly effective utilization of the available installation volume.
  • the insert E includes a support ring 7, a base part 8 and a power supply unit S.
  • the power supply unit S is designed to be connected to a power supply of a building installation technology and to convert the provided voltage into a required supply voltage, for example 3.5V.
  • at least one sensor X here: two sensors X, is housed in the base part 8 of the insert E, which are suitable for detecting the insertion depth of plug pins ST to be inserted into the openings of the center piece 3 .
  • the sensors X are localized on the printed circuit board LE in the base part 8, while the printed circuit board LE is accommodated in a housing formed from a housing base G and a housing cover GD.
  • the socket 1 has an evaluation unit that is suitable for evaluating whether the detected insertion depth is correct.
  • the socket 1 is connected to a switchable relay R, which relay R can be switched depending on the detection of the insertion depth or the evaluation.
  • the relay R is arranged, for example, in the base part 8 or adjacent to the printed circuit board LE.
  • Insert E shown shows sensors X in more detail. These sensors X are designed as two short-stroke buttons that are mechanically actuated by the plug pins ST to be inserted and, in conjunction with the evaluation unit, provide discrete information as to whether the detected insertion depth is correct.
  • FIG 3 shows the socket 1 according to the invention, in particular the insert E, in a plan view.
  • the two sensors X can be seen in this.
  • the printed circuit board LE accommodated in the housing and on which the sensors X are arranged is also shown.
  • Such a housing allows a high degree of modularity to be achieved.
  • FIG 4 visualizes the socket 1 according to the invention in cross section, once before reaching the required, proper insertion depth of a plug pin ST (left) and once upon reaching the same (right).
  • the sensor X When plugging in the connector pin ST, the sensor X is mechanically compressed, the sensor X being a pressure sensor. This compression, which results in a pressure, can be converted, for example, via the evaluation unit into a corresponding signal for switching the relay R arranged on the wall side of the printed circuit board LE.
  • FIG 5 is a representation of a socket 1 according to the invention in a cross-sectional representation, wherein the sensor X is a magnetic sensor that detects the extent to which the magnet M located on a plug pin ST approaches the sensor X in the insertion direction and the insertion depth is thus determined.
  • the signal can be routed to the printed circuit board LE via a cable connected to the sensor X.
