Definitions

  • the present invention relates generally to the field of plug connections and in particular that of plug connections in the industrial environment. Specifically, the present invention relates to an add-on housing arrangement with an add-on housing for receiving a sleeve housing of a connector with plug contacts and a mechanical locking arrangement for mechanically locking the sleeve housing on the add-on housing and a method for unlocking a mechanical lock of a sleeve housing of a connector with plug contacts on an add-on housing.
  • Arrangements are known in which the sleeve housing and the attachment housing of a plug connection are locked to one another via a mechanical lock, the locking being particularly important to the effect that the plug connection is secured against accidental loosening, so that the plug connection still exists when an occasional pull on the line occurs, the locking also being effective against shaking loose due to vibrations.
  • the pamphlet EP 2 705 974 A1 discloses a vehicle charger configured to switch a power supply switch to interrupt a power supply path. A locking portion of an actuator is then withdrawn to release the lock. It is also disclosed to issue a warning message in response to an error signal.
  • the pamphlet EP 1 017 262 A1 discloses a subrack with a plug-in assembly which is movable into and out of a rear end position with an insertion and removal handle.
  • An additional spring-actuated latch on the front which inevitably secures the insertion and removal handle in the rear end position, actuates a switching element for active switching of the plug-in module after an effective locking position has been reached. Depressing the bolt causes a passive circuit in the locked state before the insertion and removal handle is unlocked after a further distance of displacement of the bolt and the unlocking mechanically stores the unlocking in cooperation with the bolt.
  • the pamphlet EP 2 293 392 A2 discloses a device and a method for locking a plug in a socket which is arranged integrated in a charging station or in a vehicle which can be operated by means of electrical energy. It has a movably mounted latching element which, in a latching position, engages in a recess of the plug to connect it to the socket. It also has a locking element which can be actuated by means of a drive unit. The latching element can be locked in a locking position of the locking element in the recess of the plug and can be released in a release position of the locking element.
  • the pamphlet WO 2013/132808 A1 discloses a connector which is provided with a housing, a locking bracket and a locking mechanism.
  • the locking mechanism is arranged on the housing and the lever.
  • the pamphlet US 2013/0040486 A1 discloses a manual unlocking structure which is arranged in a locking device for locking a power supply plug to a power receiving connector arranged in a vehicle.
  • the power plug contains a hook.
  • the locking device comprises a fastening element which can fasten the hook on the power receiving connector in order to lock the power supply plug on the power receiving connector.
  • the manual release structure includes an actuator that can be manually operated to move and disconnect the fastener from the hook.
  • a user operates the operating element in order to manually unlock the power supply plug.
  • a control box is arranged in the vehicle and is used for manual operation of the control element in the vehicle.
  • the pamphlet DE 10 2009 042 568 A1 discloses a plug-in coupling system for the transmission of high-power electrical energy and for the transmission of a pressurized fluid.
  • the plug-in coupling system consists of at least one coupling plug and at least one coupling socket, each with at least one electrical conductor.
  • the coupling plug can be inserted into the coupling socket to form a coupled state and can be removed from the coupling socket to form a decoupled state.
  • the plug-in coupling system advantageously has at least one electromechanical protection system, consisting of at least one electronic switching means and at least one mechanical switching means arranged within the coupling socket and / or the coupling plug for producing or disconnecting the electrical conductive connection.
  • the electronic switching means and the mechanical switching means can be controlled independently of one another.
  • an add-on housing arrangement is proposed as defined in claim 1, namely with an add-on housing for receiving a sleeve housing of a connector with plug contacts, a mechanical locking arrangement for mechanically locking the sleeve housing on the add-on housing, a locking arrangement for locking the mechanical locking arrangement at least in a locking state and a control unit for controlling the locking arrangement, the control unit being designed to only control the locking arrangement to release a locking of the locking arrangement when the plug contacts are free of current and voltage within specified tolerances.
  • a method for unlocking a mechanical locking of a sleeve housing of a connector with plug contacts on an add-on housing of an add-on housing arrangement is proposed, as is defined in claim 11, namely a method in which the add-on housing arrangement comprises a locking arrangement that includes the mechanical locking arrangement locked in a locking state and with the steps of checking that the plug contacts are free of current and voltage within specified tolerances, releasing the locking of the locking arrangement by the locking arrangement after testing when the plug contacts are free of current and voltage within the specified tolerances, and of unlocking the lock of the spout housing after releasing the lock.
  • the lock which is conventionally to be released directly by a user, does not provide any security against a deliberately brought about release of the plug connection, which as such can be associated with a security risk for the operation and in particular for the user.
  • these technical features can interact with one another and characterize the locking and unlocking method.
  • the plug connector is not pulled under load, whereby it is preferably achieved that in the unplugged state the power contacts on the mains side are always switched to a voltage-free state.
  • the machine side is also checked to ensure that there is no voltage. The mechanism remains locked, especially as long as a potentially dangerous residual voltage is (still) present on the machine side. The protection of people and machines can therefore be improved with the invention.
  • the add-on housing arrangement further comprises a circuit breaker, in particular a contactor, for interrupting a line leading to a plug contact, and a voltage measuring unit for measuring a voltage applied to the plug contact, the voltage measuring unit with regard to the line between the Switching interruption and the plug contact is arranged.
  • the plug connection can be separated from the mains side, with the voltage measuring unit between the switching interruption and the plug contacts being used to detect any (residual) voltage that may still be present in the switched-off state Avoid danger from this (residual) voltage, which would otherwise be accessible if the plug-in connection was loosened.
  • the mechanical locking arrangement has at least one locking bracket which is in engagement with the spout housing in the locked state, the locking arrangement having a locking slide which is applied to the locking bracket by a spring load, and a definition for the Has locking slide in a position resting against the locking bracket in the locked state.
  • locking brackets for locking is known as such, although known locking brackets can advantageously be further developed with a fixable locking slide for use within the scope of the present invention without a modification to the locking bracket itself being necessary. This allows conventional add-on housings to be used within the scope of the invention.
  • the locking bracket itself can have a latching mechanism for fixing it in the locking state.
  • the locking bracket can have latching means, in particular a spring-loaded retractable latching hook, for locking the pivoting movement of the locking bracket in its locking state.
  • latching means in particular a spring-loaded retractable latching hook
  • the locking bracket has a locking area and an actuating area, between which a bearing axis is arranged.
  • the locking bracket can particularly advantageously be held pivotably on the add-on housing in the form of a rocker via this bearing axis.
  • the latching mechanism can then advantageously be arranged in or on the actuation area of the locking bracket and can in particular be part of this actuation area.
  • the actuation area of the locking bracket can be moved towards the attachment housing, while on the other hand the locking area of the locking bracket is pivoted in the opposite direction, i.e. moving away from the attachment housing, with its reverse locking ends via locking pins of the sleeve housing to lock the sleeve housing on the add-on housing.
  • the locking bracket is then with its actuation area and in particular with its locking mechanism at least in the vicinity of the add-on housing and can thus latch in a particularly advantageous manner on the correspondingly modified locking arrangement of the add-on housing.
  • the locking bracket can have a U-shaped basic shape with an actuating handle and two side parts extending perpendicularly therefrom, the free ends of the side parts (that is to say at the ends) forming the locking area.
  • the operating handle belongs to the operating area.
  • a fastening device for the bearing axis can be located in each of the two side parts.
  • This fastening device can, for example, consist of a cylindrical through opening each as an end receptacle for the bearing axis.
  • the bearing axis and in particular the fastening device provided for the side parts can thus be viewed as the boundary between the actuation area and the locking area of the locking bracket.
  • the locking arrangement of the add-on housing can be modified in such a way that it has a release lever which is connected to a plunger of a lifting magnet.
  • a disengaging hook for interacting with the locking mechanism can be molded onto the end of the unlocking lever.
  • the said locking hook can be spring-loaded into the locking bracket, in particular in a receiving chamber provided for this purpose, sunk, in other words, pushed into the locking bracket, in order to release the locking bracket from latching.
  • the locking bracket can then be released manually, that is to say transferred from its locking position to its unlocking position.
  • the previous unlocking can thus be effected by the lifting magnet, i.e. ultimately, for example, by an electrical signal, in particular an electrical current flow through a coil of the lifting magnet.
  • an electrical signal in particular an electrical current flow through a coil of the lifting magnet.
  • the locking hook of the locking mechanism is automatically in its locking position due to the spring force. This is particularly advantageous for safety reasons, because it avoids unintentional unlocking, e.g. as a result of a power failure, e.g. by disconnecting the corresponding contact from a corresponding power source, etc.
  • the locking bracket then latches in its locking position. To release the locking bracket, a current must flow accordingly, e.g. through the coil of the lifting magnet.
  • the latching mechanism can have a receiving chamber, which is preferably arranged centrally in the actuation area of the locking bracket, for receiving the latching hook.
  • the receiving chamber can have a window pointing in the direction of the locking arrangement in the locked state.
  • the receiving chamber can have a holding opening, in particular in the form of a cylindrical bore.
  • a, in particular cylindrical, locking axis can be held displaceably with its first end, the locking axis protruding into the interior of the receiving chamber with a second end opposite the first end.
  • the latching hook can be attached to this second end, for example screwed on or molded on.
  • Said spring loading of the locking hook can then preferably be generated by a spiral spring.
  • the locking axis can reach through the spiral spring.
  • the spiral spring can act on the one hand on an inner wall of the receiving chamber in the area around the holding opening and on the other hand on the latching hook. As a result, it is set up to move the latching hook with the spring force of the spiral spring from its unlocking position at least partially through the window into its latching position.
  • the latching hook At its end protruding from the window, has a slide-on bevel and a latching surface through which it interacts in a locking manner with the locking arrangement when the locking lever is closed.
  • This interaction can be designed in such a way that the locking bracket is initially pushed into the receiving chamber against the spring force by its slide-on slope when the locking bracket is closed, in order then to slide into a latching recess by the spring force of the spiral spring or at least to latch on a locking surface of a latching device of the add-on housing .
  • the latching hook Adjacent to the locking axis, can have at least one step directed from the inside in the direction of the window as a stop, so that it cannot be pushed completely out of the window by the spring force of the spiral spring.
  • two opposing locking brackets are often used, these preferably (but not necessarily) both being designed as described here.
  • a position detection is provided which is designed to detect whether the locking arrangement is in the locking state.
  • the position detection reports the status with regard to the locking to the control unit, which can then carry out appropriate controls.
  • the add-on housing arrangement comprises a switching interruption, in particular a contactor, for interrupting a line that leads to a plug contact, the control unit being designed to control the switching interruption, the control unit only activating the switching interruption when the line is closed drive when the position detection detects that the locking arrangement is in the locking state.
  • the information regarding the locking status can thus be used to prevent a line-side voltage from reaching the contacts in the add-on housing while the plug connection itself has not yet been reached.
  • the add-on housing arrangement comprises an operating unit, the control unit being designed to control the switching interruption only in response to an operation of the operating unit to close the line.
  • the add-on housing arrangement has an operating unit, the control unit being designed to control the locking arrangement only in response to an operation of the operating unit to release the locking of the locking arrangement.
  • At least two independent controls are provided, namely the operation of the control unit, e.g. in the form of pressing a button or the like, and the release of the lock, so that overall better security can be achieved with this too.
  • a signal output unit is provided which is designed to output a signal indicating an operating state of the add-on housing arrangement
  • a signal output allows the user to easily recognize the state of the plug connection or the arrangement as a whole, so that the user can also see which steps are currently possible or which steps may be necessary, for example to adjust the plug connection to solve.
  • a computer program with program means which cause the control unit of an add-on housing arrangement according to the invention to release the locking of the locking arrangement by the locking arrangement after checking that the plug contacts are free of current and voltage within specified tolerances if the Plug contacts are free of current and voltage within the specified tolerances when the computer program is executed by the control unit.

  • the receiving chamber 124 ' has a window 120'. Opposite the window 120 'it has a holding opening 123' in the form of a cylindrical through-hole. To facilitate assembly, it is advantageous that this bore is continuous, that is to say emerges from the locking bracket on the handle side.
  • a cylindrical locking axis 126 ' is held displaceably with its first end in this holding opening 124' and protrudes with its second end into the interior of the receiving chamber 124 '.
  • the latching hook 121 ' is attached to this second end, e.g. screwed on or molded on.
  • the locking axis 126 ' passes through a spiral spring 122'.
  • the spiral spring engages on the one hand on the area around the through opening 123 'and on the other hand on the latching hook 121'. As a result, it is set up to move the locking hook 121 'with a spring force corresponding to its deflection from its unlocking position through the window 120' of the receiving chamber 124 'into its locking position.
  • the latching hook 121 ' has at its end protruding from the window 120' a slide-on bevel directed to the bottom left in the drawing and a latching surface directed upward in the drawing, by means of which it interacts with the corresponding locking arrangement 13 'in a latching manner when the locking bracket 12' is closed .
  • the slide-on bevel and the locking surface are not provided with a reference symbol for reasons of clarity.
  • the locked state of the latching mechanism 127 'shown in the figure is thus characterized in that the latching hook 121' with its latching surface protrudes far enough out of the window 120 'to be in a latching recess or at least on a counter-latching surface of the add-on housing 11' (see FIG Figure 8c ) to lock into place.
  • the illustrated locked state of the locking mechanism 127 ' is thus characterized in that the locking hook 121' dips deep enough into the receiving chamber 124 'to unlock from the locking recess 134' or the counter-locking surface of the add-on housing 11 '.
  • the Figure 8a shows the lifting magnet 20 'with its plunger 21' and a release lever 131 'movably attached to the plunger 21' via a pivot axis.
  • a release hook 132 ' is formed on the end of the release lever 131'.
  • the unlocking lever 131 'and the unlocking hook 132' are part of the modified locking arrangement 13 '. It can easily be seen that a plunger 21 'moving in the direction of the arrow automatically causes a lever movement of the unlocking lever 131'. As a result, the unlocking hook 132 'pushes the locking hook 121' deep enough into the receiving chamber 124 'to remove it from a locking recess 134' of the attachment housing 11 'and to separate its locking surface from the counter-locking surface of a locking device 133' of the attachment housing 11 '.
  • the Figure 8c shows such an add-on housing 11 'with a latching device 133' through which a latching recess 134 'is formed.
  • the unlocking lever 131 'with the unlocking hook 132' is arranged therein. It is easy to imagine how the locking bracket 12 ', which is locked on the locking device 133' by means of its locking mechanism 127 ', can be unlocked with the aid of the unlocking pin 132'.
