Description

The invention relates to a plug with a power connection and a system with a plug and a socket.In vehicles, sockets according to DIN ISO 4165 or combined socket cigarette lighter according to SAE J 563 are frequently installed. In order to operate different electrical devices with such sockets, different adapters are required in each case.EP 1 194 983 B1 discloses an electromechanical connecting device having a current or data supply device which is arranged in a housing and has switching magnets or magnetic switching parts and contact elements, wherein the contact elements of one of the two devices (current or data supply device) are arranged in an at least partially elastic wall of the associated housing.EP 1 342 295 B1 discloses an electromechanical connecting device having a current generator housing and a current collector housing, which can be forcibly connected to one another and disconnected by a rotating device.The object underlying the invention is to provide a plug and a plug-and-socket system which help to allow electrical devices to be easily connected to an electrical grid.The object is achieved by the independent patent claims. Advantageous embodiments are characterized in the dependent claims.According to a first aspect, the invention is distinguished on the one hand by a plug and on the other hand by a corresponding system with the plug. The plug has a base body with a first side. The plug has a power connection with at least two power contacts. The power connection is arranged on the first side of the base body. The power contacts include permanent magnets for magnetic coupling with a socket. The power connection is rotatable relative to the base body. The plug has at least two adapter connections, which are each electrically coupled to the power connection. In each case one of the adapter connections is arranged on in each case one further side of the main body. The corresponding system furthermore has a socket with a socket body in which a plug connection is arranged. The plug connection has at least two power contacts, which have permanent magnets for magnetic coupling to the plug.By means of the at least two adapter connections, different devices can be coupled to the plug, for example, simultaneously, so that these can be charged, for example. Since the current contacts of the plug comprise permanent magnets, the plug is correctly aligned to the socket, if appropriate, by the magnetic force. Thus, a simple connection of the plug and socket is possible. It is thus possible, in particular in vehicles, if appropriate without looking at them, to connect the plug to the socket and thus to connect the adapter connections to the on-board power supply system of the vehicle. Because the power connection is rotatable relative to the base body of the plug, the plug can be rotated by a user in a plugged-in state in the manner it desires, for example, with an adapter connection on a desired side.A permanent magnet in this context is a magnet made of a piece of a magnetizable material, such as iron, cobalt, nickel and / or ferrite, for example, which retains its static magnetic field without requiring an electric current flow, as in the case of electromagnets.According to an advantageous embodiment, the base body of the plug is cube-shaped.As a result, the plug has a very compact construction. Furthermore, as a result of the cube-shaped configuration, up to five adapter connections can be arranged on five sides of the cube.According to a further advantageous embodiment, the adapter connections are each designed for a different USB plug type and / or for a different mobile telephone connection.As a result, a large number of small electrical devices, which are intended to be charged and / or operated in a vehicle, for example, can be connected to the plug.According to a further advantageous embodiment, a magnetic north pole is formed on a contact surface in one of the current contacts of the plug. In the other current contact of the plug, a magnetic south pole is formed on a contact surface.As a result, the plug can be coded in order, if appropriate, to avoid polarity reversal.According to a second aspect, the invention is distinguished by a corresponding system with a bushing. The socket has a socket body in which a plug connection is arranged, wherein the plug connection has at least two current contacts which have permanent magnets for magnetic coupling to a plug. The plug terminal is rotatable relative to the socket body. The corresponding system furthermore has a plug with a base body with a first side. The plug furthermore has a power connection with at least two power contacts. The power connection is arranged on the first side of the power body. The power contacts include permanent magnets for magnetic coupling with the socket. The plug has at least two adapter connections, which are each electrically coupled to the power connection. In each case one of the adapter connections is arranged on in each case one further side of the main body.According to an advantageous embodiment, the base body of the plug is cube-shaped.As a result, the plug has a very compact construction. Furthermore, as a result of the cube-shaped configuration, up to five adapter connections can be arranged on five sides of the cube.According to a further advantageous embodiment, the adapter connections are each designed for a different USB plug type and / or for a different mobile telephone connection.As a result, a large number of small electrical devices, which are intended to be charged and / or operated in a vehicle, for example, can be connected to the plug.According to a further advantageous embodiment, a magnetic north pole is formed on a contact surface in one of the current contacts of the plug. In the other current contact of the plug, a magnetic south pole is formed on a contact surface. In one of the current contacts of the socket, a magnetic north pole is formed on a contact surface. In the other current contact of the socket, a magnetic south pole is formed on a contact surface for the magnetic coupling of the plug to the socket by means of the contact surfaces of the current contacts of the plug and the contact surfaces of the current contacts of the socket.As a result, the plug and socket can be coded to match one another, so that polarity reversal can be ruled out. Furthermore, the contact surfaces thereby attract each other, whereby the plug can be connected to the book very easily, if necessary without looking at it.Exemplary embodiments are described below with reference to the schematic drawings.The following are shown: FIG. 1 shows a plug connector, and FIG. 2 shows a system with the plug and a socket.Elements of the same construction or function are identified with the same reference numerals across the figures.FIG. 1 shows a plug 1. the plug 1 has a base body 3. The base body 3 is, for example, cubic. On a first side of the base body 3, a power connection 5 is arranged with at least two power contacts 7.The current contacts 7 have permanent magnets for magnetic coupling to a socket 10. In one of the current contacts 7, for example, a magnetic north pole is formed on the contact surface and in the other current contact 7 a magnetic south pole is formed on the contact surface.On the other sides of the base body 3, an adapter connection 9 can be formed in each case, which is electrically coupled to the power connection 5 in each case. By means of the cube-shaped form of the base body 3, for example, up to five adapter connections 9 can be realized.The adapter connections 9 are each designed, for example, for a different USB plug type, such as, for example, micro-USB, mini-USB, standard USB, per type A or B, and / or for a different mobile telephone connection.For example, a voltage converter is additionally arranged in the plug 1, for example for converting from a 12 V or 24 V supply voltage, such as an on-board voltage of a vehicle, into a 5 V voltage.FIG. 2 shows a system with the plug 1 and a socket 10. The bushing body 15 can also be, for example, a part of a wall in which the bushing 10 is arranged, such as, for example, a glove compartment, a central console, a central armrest in the rear region of a vehicle and / or a trunk.A plug connection 12 is arranged in the socket body 15, wherein the plug connection 12 has at least two current contacts 14 which have permanent magnets for magnetic coupling with the plug 1.In one of the current contacts 14 of the socket 10, a magnetic north pole is formed, for example, on a contact surface. In the case of the other current contact 14 of the socket 10 on a contact surface, a magnetic south pole, for example, is formed for the magnetic coupling of the plug 1 to the socket 10 by means of the contact surfaces of the current contacts 7 of the plug 1 and the contact surfaces of the current contacts 14 of the socket 10.As a result, the plug 1 and the socket 10 can be coded to match one another, so that polarity reversal can be ruled out. Furthermore, the contact surfaces thereby attract each other, whereby the plug 1 can be connected to the book 10 very easily, if necessary without looking at it.The power connection 5 of the plug 1 is rotatable relative to the base body 3, for example. Alternatively or additionally, the plug connection 12 of the socket 10 is rotatable relative to the socket body 15, for example. As a result, the plug 1 can be rotated by a user in the inserted state in the manner that it desires, for example, to be an adapter connection 9 on a desired side.The socket 10 additionally has, for example, a switching unit which is designed such that the plug connections 12 of the socket 10 are only coupled to the electrical supply grid when the plug 1 is magnetically coupled to the socket 10. As a result, short circuits due to conductive objects coming into contact with the socket 10 can be prevented, if necessary.List of reference characters1 Plug 3 Base body 5 Power connection 7 Power contact 9 Adapter connection 10 Socket 12 Plug connection 14 Power contact 15 Socket body
