Definitions
- the invention relates to an adapter plug for DC voltage disconnection, with a housing, with a first connection for connecting a first electrical line and with a second connection for connecting a second electrical line, with an electrically conductive, switchable connection is realized.
- Adapter plugs have been known from the prior art for many years and are inserted between at least a first single-wire or multi-wire electrical line and at least a second single-wire or multi-wire electrical line and connect the two electrical lines to one another.
- the adapter plugs can take on very different functions.
- adapter plugs are known from the prior art, which are used for DC voltage shutdown.
- an arc occurs when the electrical lines—or at least one of the electrical lines—are disconnected from the adapter plug under load.
- the arc will continue until the contacts are at a sufficient distance from each other to interrupt the arc or until the current is interrupted elsewhere. It is also possible to extinguish the arc in some other way, but appropriate measures are necessary for this.
- the problem is that a burning arc can cause significant damage to the components between which it occurs. In particular, insulation or connections can be damaged, but a burning arc can also damage neighboring components and devices. Last but not least, a burning arc can injure a user. The danger emanating from a burning arc is all the greater, the higher the operating voltage of the respective network.
- the invention is based on the object of providing an intermediate plug for DC voltage disconnection, with which the occurrence of an arc when disconnecting an electrical line connected to the intermediate plug is prevented in a simple manner.
- the object is achieved by an adapter according to claim 1.
- the adapter according to the invention is designed such that in the Housing a switching device for switching the electrically conductive connec tion between the first terminal and the second terminal is arranged.
- the switching device can be brought from a first switching state to a second switching state, the electrically conductive connection being disconnected and/or current-blocking in the first switching state and the electrically conductive connection being closed and/or current-conducting in the second switching state.
- the current flow between the first connection and the second connection is thus interrupted by bringing the switching device from the second switching state into the first switching state. If the switching device is in the first switching state, i.e. in the switching state in which the electrically conductive connection is disconnected and/or current-blocking, the electrical lines connected to the intermediate plug can be disconnected from the intermediate plug without an arc occurring, since it is no longer disconnected under load.
- the adapter plug according to the invention also has a locking device for locking the first line in the connected state and for locking the second line in the connected state.
- the Ver locking device can be brought from an unlocked position into a locked position.
- the locking device ensures that an electrical line connected to the intermediate plug cannot be accidentally separated from the intermediate plug. Accidentally disconnecting an electrical line under load can result in an arc. Since an electrical line can only be separated from the intermediate plug when the locking device has previously been moved from the locked position to the unlocked position, accidental separation of an electrical line is at least not possible, so that no damage is caused by an arc can arise.
- the switching device is moved from the first switching state to the second switching state by moving the locking device from the unlocked position to the locking position. Accordingly, the switching device is then also brought from the second switching state into the first switching state by moving the locking device from the locking position into the unlocking position. According to the invention, the switching device is switched by locking or unlocking the locking device. It is thus achieved according to the invention that the electrically conductive connection between the first connection and the second connection is disconnected and/or is switched off when a connected line can be disconnected from the intermediate plug.
- the intermediate plug according to the invention thus not only prevents the unintentional disconnection of a line from the intermediate plug by the locking device, but also realizes that a line can only be disconnected if the connection between the two connections of the intermediate plug has previously been interrupted, i.e. a line is disconnected is prevented under load.
- the adapter plug in the housing also has a switching device for switching the electrically conductive connection between the first connection and the second connection, it being possible for the switching device to be brought from a first switching state into a second switching state, with the electrically conductive connection is disconnected and/or current-blocking and in the second switching state the electrically conductive connection is closed and/or is current-conducting.
- the intermediate plug has a detection device, the detection device detecting a connection or disconnection of an electrical line with a connection of the intermediate plug.
- connection process or the disconnection process not only includes the connection process or the disconnection process as such, but it can also be detected whether a line is connected or disconnected, i.e. the states “line connected ' or 'line disconnected'.
- the switching device is designed in such a way that when it detects that both electrical lines are connected—or, as explained above, when the “line connected” state is detected—it changes to the second switching state with the two terminals and that when it detects a disconnection of one electrical line - or when the "line disconnected” status is detected - changes to the first switching state with this connection.
- the intermediate plug according to the invention has the advantage that a current flow between the first connection and the second connection is interrupted as soon as one of the lines connections is separated from a connection of the adapter plug. This prevents an arc from occurring when the electrical cable is disconnected, since the disconnection process is no longer carried out under load.
- the locking device is formed from a first locking unit for locking the first line and from a second locking unit for locking the second line.
- the first locking unit and the second locking unit can be locked independently of one another.
- the switching device is moved from the second switching state to the first switching state both by moving the first locking unit from the locked position to the unlocked position, and by moving the second locking unit from the locked position to the unlocked position from the second switching state the first switching state is introduced ver and vice versa.
- the locking device is implemented as a mechanical locking device.
- the locking device has at least one mechanical locking element with which the connected line or lines are locked. More preferably, the mechanical locking element is moved mechanically.
- the locking element has a frame-like structure that encompasses the electrical line.
- the locking element is implemented as a locking pin.
- the locking device is designed in such a way that it locks in the locking position.
- the locking device for example, a Have locking lug, example, in a corresponding recess in the housing engages.
- the locking device can have a latching recess into which a latching lug arranged, for example, on the housing latches.
- the locking device is implemented as an electromechanical locking device.
- a mechanical locking element is electrically brought into a locking position.
- at least one locking pin is driven and moved electrically.
- a further variant of the adapter plug is characterized in that the locking device is implemented as an electromagnetic locking device.
- the intermediate plug has a detection device that detects a connection or disconnection of an electrical line with a connection of the intermediate plug
- the detection device is implemented in a preferred variant by at least one proximity sensor.
- a proximity sensor is formed in each of the two connections of the adapter plug.
- at least one proximity sensor is formed on the housing in the area of at least one connection.
- the detection device is implemented by pilot contacts in at least one connection, preferably in both connections.
- the pilot contacts are designed to be shorter than the connection contacts, so that when the connection between the adapter plug and the electrical line is separated, the electrical connection between the pilot contacts and the corresponding counter pilot contacts is separated first.
- the adapter plug is particularly preferably designed in such a way that the separation of the pilot contacts from the corresponding mating contacts triggers an electronic system or a mechanical switch which interrupts the electrically conductive connection between the first connection and the second connection before the main contacts between the connection and plugs are separated.
- the control device is implemented electronically. More preferably, the control device has at least one semiconductor component. This semiconductor component changes from a current-conducting state to a current-blocking state when the locking device is moved from the locked position to the unlocked position. Thus, the electrically conductive connection between the first terminal and the second terminal is current-blocking as soon as the locking device is moved from the locked position to the unlocked position.
- a further preferred embodiment of the intermediate plug according to the invention is characterized in that the switching device is implemented mechanically.
- the switching device preferably has a mechanical contact with which the electrically conductive connection is separated or closed.
- a further embodiment is characterized in that the Schahein direction is activated by at least one auxiliary circuit.
- the auxiliary circuit itself is particularly preferably activated by the locking device, or by mechanical drivers or by electronic switches or buttons.
- a particularly preferred variant of the intermediate plug according to the invention is therefore characterized in that an arc extinguishing device for extinguishing an arc formed within the housing is arranged in the housing.
- the arc extinguishing device can be implemented in a manner known from the prior art be, the invention is not limited to a specific realization of the arc quenching device.
- the arc can be broken off as a result of a high separation speed.
- the opening path of the contacts can be designed large enough to allow the arc to break off.
- the combination of high cutting speed and large opening path causes the arc to be broken off and thus extinguished.
- the precise selection of the separation speed and the opening path depend on the applied load.
- Arc extinguishing agents can also be installed in the adapter plug, in particular extinguishing combs or blowout magnets can be provided in order to extinguish an arc.
- Another variant envisages changing the arc medium in order to extinguish the arc. All known measures can be combined with the adapter according to the invention.
- a preferred embodiment is characterized in that the connections for the electrical lines are each arranged in a receptacle and that the receptacles are detachably connected to the housing.
- the receptacles are thus preferably implemented as interchangeable, so that different receptacles can be connected to the housing of the intermediate plug.
- the various receptacles can be designed to accommodate various connections to the electrical lines, so that the intermediate plug can be connected to a large number of different connections.

- FIG. The intermediate plug 1 has a housing 2, which is preferably made of plastic and in particular special from the two perspective views of FIG. 3 is recognizable bar.
- the shape of the housing 2 is not limited to the cuboid shape shown here as an example, but can also have other geometric shapes.
- the intermediate plug 1 has a first connection 3 for connecting a first electrical line and a second connection 4 for connecting a second electrical line.
- An electrically conductive, switchable connection 5 is provided between the first connection 3 and the second connection 4 .
- a first connector plug 6 and a second connector plug 7 are shown, to each of which one end of an electrical line can be connected.
- the two connectors 6, 7 can each with one of the two Connections 3, 4 are connected in such a way that the two lines are mechanically and electrically connected to the intermediate plug 1.
- a switching device 8 for switching the electrically conductive connection 5 is also arranged in the housing 2 of the intermediate plug 1 .
- the control device 8 can have a first control state or a second control state. In the first switching state of the switching device 8 shown in Figs. individual conductors of terminal 4 are connected. In the in Figs. lb and
- the electrically conductive connection 5 is closed or current-carrying, so that the conductors of the first connection routed via the shatable connection 5
- first connection 3 and the second connection 4 have, in addition to the conductors routed via the accessible connection 5, further conductors which are permanently connected to one another.

- the lines or the connection plugs 6, 7 cannot be separated from the intermediate plug 1. If, on the other hand, the locking units 9, 10 are in their unlocking position according to FIGS. 1a and 2a, the two connection plugs 6, 7 or the two lines connected to the connection plugs 6, 7 are separated from the intermediate plug 1 and thus also from the two connections 3, 4 who the. So that an arc does not occur when the lines connected to the intermediate plug 1 via the connecting plugs 6, 7 are disconnected, the switching device 8 is moved from its second switching state to its first switching state when the locking device is moved from the locked position to the unlocked position . The electrically conductive, switchable connection 5 is thus disconnected or switched to blocking the current before the lines can be disconnected from the intermediate connector 1 when the locking units 9, 10 are unlocked.
