Description
Title of the invention: DEVICE, IN PARTICULAR POWER SOCKET, COMPRISING AN ELECTRONIC CIRCUIT, DESIGNED FOR THE CONTROLLED CONNECTION OF ELECTRICAL CONNECTIONS TO A VOLTAGE SUPPLY Domain
[0001] The present invention relates to a device for connecting electrical connections in a controlled manner to a voltage supply. In particular, the present invention relates to a device with an electronic circuit designed for connecting electrical connections in a controlled manner to a voltage supply or for disconnecting them from it. Background
[0002] When connecting electrical connections to a power supply and disconnecting them from it, it may happen, particularly in the case of high voltages, that an electric arc may appear between the electrical connections and the power supply. Presentation of the invention
[0003] A device according to the invention comprises a first clamping point forming a first electrical connection, a second clamping point forming a second electrical connection and an electronic circuit which, when a plug is inserted into the device, is activated by a movement of a component mounted in the device or, when the plug is removed, is activated by a repositioning of the component mounted in the device, the activated electronic circuit being designed to connect a voltage supply to the first electrical connection and / or the second electrical connection or to separate the voltage supply from the first electrical connection and / or the second electrical connection.
[0004] The term "electrical connection," as used in the description and claims, refers in particular to an electrically conductive contact point intended for temporary or permanent electrical connection to an electrical conductor. Furthermore, the term "clamping point," as used in the description and claims, refers in particular to a structure designed to establish a frictional connection with an electrical conductor inserted into the clamping point. Moreover, the term "electronic circuit," as used in the description and claims, refers in particular to a functional unit, which is made up of electrical and electronic components. Furthermore, the term "activated circuit" as used in the description and claims means, in particular, a circuit which receives signals through circuit inputs and processes them and derives control measures from the processed signals.
[0005] The voltage supply can be a direct current voltage source or an alternating current voltage source.
[0006] If the voltage source is an alternating voltage source, the electronic circuit can be designed to connect the voltage supply to the first electrical connection and / or the second electrical connection during a zero crossing of an alternating voltage supplied by the voltage supply.
[0007] The electronic circuit can be designed to separate the voltage supply connected to the first electrical connection and the second electrical connection from the first electrical connection and / or the second electrical connection during a zero crossing of the alternating voltage.
[0008] The component can be mounted in the device so as to be able to move against a spring force and be designed so that, when the plug is inserted, it is moved by contact with the plug from a rest position before a first contact pin of the plug comes into contact with the first clamping point and a second contact pin of the plug comes into contact with the second clamping point.
[0009] The component may have an electrically conductive part which, when the plug is inserted, comes into electrically conductive contact with a third electrical contact point of the electronic circuit and a fourth electrical contact point of the electronic circuit and thus closes an electrical circuit.
[0010] The electrically conductive part can be disposed between a first electrically non-conductive part and a second electrically non-conductive part of the component and the first electrically non-conductive part can, in the rest situation, be in contact with the first electrical contact point of the electronic circuit and the second electrical contact point of the electronic circuit.
[0011] The second electrically non-conductive part can be in contact with the first electrical contact point of the electronic circuit and the second electrical contact point of the electronic circuit, when the plug is inserted into the device.
[0012] A closure of the electrical circuit at the contact points can cause the voltage supply connected to the first electrical connection and the second electrical connection to be separated from the first and / or second electrical connection during a zero crossing of the alternating voltage through the electronic circuit and the first and second electrical connections. Electrical connections can remain separate from the power supply as long as the electrical circuit is closed.
[0013] An opening of the electrical circuit may cause the voltage supply to be connected to the first electrical connection and / or the second electrical connection during a zero crossing of the alternating voltage through the electronic circuit and the first electrical connection and the second electrical connection may remain connected to the voltage supply at the contact points as long as the electrical circuit is open.
[0014] The alternating voltage source may be a three-phase current source, and the device may have a third clamping point forming a third electrical connection and a fourth clamping point forming a fourth electrical connection. The activated electronic circuit may further be designed to connect the three-phase current source to the third and fourth electrical connections or to disconnect the three-phase current source from the third and fourth electrical connections.
[0015] If the three-phase power source is connected to the first, second, third and fourth electrical connection, the neutral conductor can be connected to the first electrical connection, the first line carrying current to the second electrical connection, the second line carrying current to the third electrical connection and the third line carrying current to the fourth electrical connection.
[0016] The electronic circuit can further be designed to connect the external conductors of the three-phase current source to the second, third and fourth electrical connection during a zero crossing of the respective phase.
[0017] The electronic circuit may feature an optical sensor, which is designed to monitor movement of the component.
[0018] The device can be implemented in the form of a power outlet.
[0019] A first plug according to the invention comprises a first contact pin, a second contact pin and an electronic circuit, which, when the plug is removed, is activated by a movement of a component mounted in the plug, the activated electronic circuit being designed to separate a load electrically connected to the contact pins of the first contact pin and / or the second contact pin.
[0020] The electronic circuit may further be designed to separate the load electrically connected to the contact pins of the first contact pin and / or the second contact pin during a zero crossing of the alternating voltage with which the load is supplied by the contact pins.
[0021] A second plug according to the invention comprises a first contact pin, a second contact pin and an electronic circuit, which, when the plug is removed, is activated by a movement of a component mounted in the plug, the activated electronic circuit being designed to electrically connect a load to the first contact pin and / or the second contact pin.
[0022] Moreover, it goes without saying that the characteristics described in connection with the device and the plugs can also be the characteristics of a process in which the device and the plugs can be used, and vice versa. Brief description of the drawings

[0034] In this context, identical or similar function elements are identified on the drawings by the same reference signs. Embodiments of the invention
[0035] Fig. 1 shows a power outlet 10 and a plug 12, which is designed and intended to be inserted into the power outlet 10. The plug 12 comprises a A housing 14 made of insulating material, from which two contact pins 16 protrude. The contact pins 16 are connected to flexible electrical conductors 18, through which an electrical load (not shown) can be supplied with energy. The plug 12 further includes a U-shaped rail 20 extending over opposite faces of the housing 14, which is provided as a protective contact and is also connected to a flexible electrical conductor 18. The flexible electrical conductors 18 are each wrapped in a flexible insulating material, which prevents electrical contact between the conductors 18. The flexible electrical conductors 18 can also be completely wrapped in a flexible insulating material to protect against damage and unwanted contact. For example, the flexible electrical conductors 18 can be the strands of a three-strand cable.
[0036] The power outlet 10 comprises a housing 22 made of an insulating material with a substantially cylindrical internal space 24, on the front face of which two openings 26 are provided, which allow the contact pins 16 to be inserted into the internal space 24. In the internal space 24 are two clamping points 28, which are connected to an electronic circuit 30. The electronic circuit 30 is further connected to a voltage supply (not shown) via two electrical conductors 32. The power outlet 10 further comprises a U-shaped rail 34 extending over the opposite internal faces of the housing 22, which is provided in the form of a protective contact and is also connected to a flexible electrical conductor 32.In this context, the free ends of the U-shaped rail 34 have curved parts in the center of the socket 10, which are designed and intended to embrace the free ends of the U-shaped rail 20 when the plug 12, as shown in [Fig.2], is inserted into the socket 10.
[0037] Furthermore, the socket 10 includes a component 36, which is mounted in the front partition wall 38 and protrudes towards the plug 12, so that the plug 12 touches the component 36 before the contact pins 16 come into contact with the clamping points 28. When the plug 12 is inserted further into the socket 10, the component 36 is moved towards the inner space 24. The component 36 is dimensioned for this purpose so that the conductive tip of the component 36, as shown in [Fig. 3], establishes an electrical contact between an output and an input of the electronic circuit 30. This activates the electronic circuit 30, which then isolates the voltage supply (not shown) from the connections formed by the clamping points 28.If the power supply (not shown) produces an alternating voltage, the electronic circuit 30 isolates the power supply (not shown) from the connections 44 at a zero crossing of the alternating voltage. In the case of a polyphase alternating voltage, the electronic circuit 30 isolates. The voltage supply (not shown) to the respective connection 44 during the zero crossing of the respective phase. As shown in [Fig. 4], the connections 44 are thus voltage-free when the contact pins 16 come into contact with the clamping points 28.
[0038] Because the plug 12 is inserted further into the power outlet 10, the electrical contact between the output and input of the electronic circuit 30 is interrupted by the fact that, as shown in [Fig. 5], an insulating portion of the component 36 is pushed between the contact points 40. This interruption of the electrical circuit causes the electronic circuit 30 to connect the power supply (not shown) to the connections 44. If the power supply (not shown) produces an alternating voltage, the electronic circuit 30 connects the power supply (not shown) to the connections 44 at a zero crossing of the alternating voltage. In the case of a polyphase alternating voltage, the electronic circuit 30 connects the power supply (not shown) to the respective connection 44 at the zero crossing of the respective phase.
[0039] As an alternative to the embodiment shown in [Fig. 1] to [Fig. 5], the electronic circuit 30 can, as shown in [Fig. 6], in the case of a corresponding shortening of the component 36, connect the power supply (not shown) to the connections 44 when the conductive tip of the component 36 establishes an electrical contact between the output and the input of the electronic circuit 30. If the electrical contact between the output and the input of the electronic circuit 30 is interrupted by the removal of the plug 12, the electronic circuit 30 disconnects the power supply (not shown) from the connections 44. Furthermore, as illustrated in [Fig. 7], the component 36 in another alternative embodiment can comprise a conductive part, which is disposed between two non-conductive parts.
[0040] In addition, the detection of the movement of component 36, as illustrated in [Fig.8], can also be carried out by means of an optical sensor 42 (for example in the form of a light barrier).
[0041] As shown in [Fig.9], the embodiments shown in [Fig.1] to [Fig.5] can be modified by arranging the electronic circuit 30 and the component 36 in the plug 46. Since the electronic circuit 30 is in this case without current, when the plug 46 is removed from the power outlet 48, the electronic circuit 30 can interrupt the electrical connection of the contact pins 16 to the load (not shown) when the plug 30 is removed (in particular during a zero crossing of an alternating voltage) and be designed to maintain the interruption for a certain time even if the electronic circuit has been without current.
[0042] Alternatively, as shown in [Fig. 10], the embodiment shown in [Fig. 6] can be modified by arranging the electronic circuit 30 and the component 36 in the plug 46.
