Definitions

  • the invention relates to an electrical socket adapter according to the preamble of claim 1 and a method for using an electrical socket adapter according to the preamble of claim 16.
  • socket adapters are known from the prior art, which are primarily used to bridge the differences between different connector systems.
  • the electrical connection between the sockets of the socket adapter, in which different connectors can be inserted, and the plug can be interrupted by providing a mechanical switch.
  • the plug is only connected to one of the plug sockets and the remaining sockets are de-energized.
  • solutions have been proposed in which the plug can be rotated relative to the adapter housing and thus the electrical connection with one of the plug sockets can be produced.
  • a touch-proof light bulb socket is disclosed.
  • the main circuit to which a bulb which can be screwed into the bulb socket, can be connected, is connected by an auxiliary circuit connected to a relay.
  • On the socket metal detectors are arranged, through which in the auxiliary circuit, a voltage is generated when a light bulb is screwed into the socket. If current flows through the auxiliary circuit, the relay closes the main circuit and the light bulb is supplied with electric current. If a light bulb with a socket with a metallic external thread is screwed into the bulb socket, electrical contacts arranged in the socket are in electrical current with which contacts of the socket are in electrical connection.
  • the switch can be realized by a relay.
  • This has the advantage that the load circuit to be switched can not be switched by a user, but that it can be switched automatically by a control circuit. A misuse is therefore excluded.
  • Another advantage is that conditions or limits can be defined when the relay closes the circuit and when it interrupts it. Conceivable conditions are, for example, a defined current intensity or a defined temperature.
  • a socket adapter according to the preamble of claim 1 in that at least one socket comprises an insertion opening for receiving a protective conductor pin and the insertion opening communicates with a metal detection, wherein upon detection of a metal in the insertion opening the circuit is interrupted by the relay.
  • a 2-pin UK plug standard BS 1363
  • 2-pin socket adapter which has usually formed a dummy of a protective conductor pins
  • this can lead to a breach of national safety regulations, as the use of 2-pin socket adapters with 3-pin plugs may be prohibited.
  • the material of the protective conductor pin of the plug is detected in the socket adapter.
  • a UK plug will therefore only receive power if it has a dummy of the protective conductor pin, typically made of plastic.
  • a UK plug with a protective conductor pin made of metal leads to an interruption of the load circuit when plugged into the socket adapter.
  • the invention pursues a completely different concept.
  • a relay at can be used with a 2-pin electrical socket adapter in order to be able to use a 2-pin UK plug with earthing pin dummy without violating national safety regulations. Inserting a 3-pin UK plug into the 2-pin plug adapter is therefore inevitably possible.
  • the metal detector is not used as usual to close the load circuit when a metal is detected, but prevents an inserted 3-pin UK plug from getting current.
  • the at least one socket for receiving a plug according to the BS 1363 standard is suitable, which standard defines a British plug. Since a UK plug according to the BS 1363 standard has either a grounding pin or a grounding pin dummy, the socket must in any case have an insertion opening for receiving a protective conductor pin.
  • the socket adapter comprises a plug-in power supply, which provides a DC voltage, preferably of 5 V.
  • a USB socket can be provided on the socket adapter to supply devices with 5V DC voltage.
  • the plug-in power supply unit provides the control circuit of the relay.
  • the control current is therefore always available and does not have to be provided by an external power source such as a battery. This means that the relay can also switch larger loads with a low-voltage source.
  • the socket adapter comprises a current measurement and the circuit can be interrupted by the relay when the power consumption of the socket adapter exceeds a limit value. This safely prevents overloads in the load circuit.
  • the invention is also preferably characterized in that the socket adapter comprises a temperature measurement and the circuit is interruptible by the relay when the temperature of the socket adapter exceeds a limit. This not only protects the adapter against excessive current loads but also against excessive temperatures.
  • the limit values for current intensity and / or temperature are stored in a microchip.
  • the limit values can be read into the microchip.
  • limits for example, 10 amps for the current load and a temperature difference of 45 K can be deposited on the microchip.
  • the microchip can be supplied with power via the already existing low-voltage source, which represents the plug-in power supply unit.
  • an iron ring is provided between the circuits.
  • the relay is a semiconductor relay, in particular a triac. Since the triac is an electronic component, it isscienceunancorpüg. In addition, triacs are very well suited for the switching of alternating current and have a compact design.
  • the triac is connected by a photo triac.
  • the photo triac allows galvanic isolation of the load circuit from the control circuit. As a result, the AC load circuit can be controlled safely with a 5 V low voltage source.
  • the plug with the sockets is conductively connected by a neutral conductor and a phase conductor and the socket adapter is free of a protective conductor.
  • the socket adapter therefore includes only 2 poles and is used for electronic and electrical devices that do not require grounding.
  • phase conductor can be switched by the relay. If the phase conductor and the neutral conductor are switched by the relay, the socket adapter has a larger design. However, the fuse is improved when both conductors are switched by the relay.
  • Another aspect of the invention relates to a method of using an electrical socket adapter with a 2-pin connector for receiving a 3-pin Connector of a consumer in a socket of the socket adapter.
  • the electrical connection between the socket and the plug is made when the protective conductor pin is not electrically conductive and the electrical connection is interrupted when the protective conductor pin is electrically conductive.
  • Figure 1 a circuit diagram of a first embodiment of an electrical
  • Figure 2 is a circuit diagram of a second embodiment of the electrical
  • FIGS. 1 and 2 show a first and second embodiment of an electrical socket adapter, which is denoted overall by the reference numeral 11.
  • the socket adapter 11 comprises a plug 13, for example a plug, which corresponds to the Swiss standard or another standard.
  • the socket adapter 11 has a phase conductor 15 and a neutral Laiter 17.
  • the conductors 15, 17 are electrically connected to at least one female connector 19.
  • the plug sockets 19 serve to accommodate plugs of different standards in order to be able to use plugs of other standards in a country in which only the plug 13 fits.
  • Such electrical socket adapters are also referred to as travel adapters or travel plugs. Socket adapters, in which a third pole, so a protective conductor is missing, may not allow in some countries, according to legal regulations, that plug with three pins can be inserted.
  • Plugs that comply with the UK standard (BS 1363) always have three pins. If no protective conductor is required for the operation of the electrical appliance, then a UK plug with a dummy of a protective conductor pin of electrically non-conductive material becamestat- tet. This results in the problem that 2-pin UK plug can not be used with 2-pin socket adapters, since the 2-pin socket adapter for safety reasons, must have no insertion for dummy of the protective conductor pins.
  • the present socket adapter solves this problem by providing an insertion opening 21 for protective conductor pins or their dummies.
  • the adapter 11 is equipped with a metal detection circuit 23.
  • the switching function for switching the load circuit is taken over by a relay 25, for example an electromechanical relay, or a semiconductor relay, for example a triac 26.
  • a relay 25 for example an electromechanical relay, or a semiconductor relay, for example a triac 26.
  • the triac 26 itself is shaded by a photo-triac 27 in order to be able to switch the triac galvanically isolated.
  • the switching elements 25, 26 can also perform other switching tasks.
  • the adapter 1 1 include a current measurement 29. If the current flowing in the load circuit exceeds a limit value, the load circuit is interrupted by the switching elements 25, 26.
  • the adapter 11 may include a temperature sensor.
  • the load circuit is also interrupted by the switching elements 25, 26.
  • the limit values for current and temperature are stored in a microchip 31 and can be imported with software.
  • a limit value for the current measurement is, for example, 16 A.
  • a temperature difference of 45 K can be specified.
  • the relay 25 and triac 26 can replace electrical fuses or temperature fuses. Such fuses burn out when they appeal and must be replaced.
  • the switching elements 25,26 close the ladder 15,17 easy This again by the adapter 11 is disconnected from the network and is plugged in again after a certain tent.
  • the socket adapter 11 comprises a plug-in power supply 33, which converts the connected alternating current into a direct current of preferably 5V.
  • the direct current can be removed, for example, at a USB socket 35.
  • the Steckemetz- part 33 provides the control circuit 37 for the switching elements 25,26 available.
  • an iron ring 39 is provided.
  • the socket adapter 1 1 makes it possible to use a 2-pin U K plug with a protective dummy dummy in other countries, without the prevailing safety laws for 2-pin sockets would be violated.
  • the socket adapter has the additional added value that the intended relay 25 or the semiconductor relay, in particular a triac 26, can be used to monitor the flowing current and the temperature of the adapter 11. Burnable fuses can therefore be dispensed with in the adapter 11.
