Definitions
- the present invention relates to a locking mechanism for a connector unit according to the preamble of claim 1.
- the invention also relates to a connector unit with such a locking mechanism, as well as a method for controlling a locking mechanism of a connector unit.
- Industrial connectors form the electrical connection component between different modules in industrial production plants. Connectors support the simple and quick exchangeability of production modules or enable the installation of complex and possibly meshed infrastructures. Energy, signals and data are preferably transmitted at the interfaces.
- the infrastructures not only affect the electrical supply with AC and DC voltages, but also information technology and other auxiliary media such as control voltages of e.g. 24V or compressed air.
- the infrastructure must also be significantly more changeable than today. It can be assumed that more decentralized infrastructure nodes will establish themselves in production, which are networked with each other and supply the individual production modules. This leads to changing infrastructure supply topologies. It can be assumed that non-expert personnel will also make changes to the assembly of production modules or changes to the decentralized infrastructure access.
- the connector can serve as a safety element to rule out danger to life and limb for the operator.
- the connector requires access to the safety-related control level of the infrastructure.
- An application example is DC voltage networks, where it is essential to prevent power lines from being disconnected. These infrastructures require connectors whose operation must be enabled by a control level of the infrastructure.
- Connector locks have been state-of-the-art for decades and ensure the necessary operational safety of industrial systems.
- Operation by unskilled users in the field of charging plugs for electromobility is evident.
- the document DE 10 2016 105 975 A1 illustrates a locking device for connectors, having a first locking means and a second locking means.
- the two locking means can be plugged into one another and latched.
- At least one blocking element is provided for latching the first locking means with the second locking means.
- the blocking element is suitable for mechanical latching and can be actuated and released via an actuator.
- an actuator is also arranged in the first locking means or the second locking means. The latching of the two locking means can be released via the actuator even if the actuator fails.
- the first locking means and the second locking means are intended for use in a plug and a corresponding mating plug.
- the solution to this problem is the object of the invention.
- the invention solves this problem with the subject matter of claim 1 .
- a locking mechanism according to the invention for a plug-in connection unit comprises a first locking assembly and a second locking assembly, wherein the locking mechanism in a blocking position allows the first locking assembly to be plugged into the second locking assembly. blocking or pulling out of the first locking assembly inserted into the second locking assembly, and wherein the locking mechanism in an unlocking position allows mating of the first locking assembly into the second locking assembly or pulling out of the first locking assembly inserted into the second locking assembly.
- the first locking assembly has a locking head with a specific geometry
- the second locking assembly has a receptacle with a through-opening with a specific geometry, with the specific geometry of the through-opening being adjusted in relation to the specific geometry of the locking head in the blocking position and/or is twisted that there is no coverage of the specific geometries, and wherein in the unlocking position the specific geometry of the through-opening is adjusted in relation to the specific geometry of the latching head and/or twisted such that the specific geometries are covered.
- a particular advantage here is that the specific geometries are easy to produce, with blocking and unlocking being able to be made possible with little installation space by advantageously simple adjustment and/or rotation of the coding elements involved.
- This adjustment movement can be a simple linear and/or curved movement.
- the adjustment movement can also include a pitching movement or tilting movement.
- the adjustment movement can also be a twisting movement or pivoting movement.
- a combination of an adjustment movement and a twisting movement or pivoting movement is also conceivable.
- a plug connection unit according to the invention with a first plug connector and a second plug connector has the locking mechanism described. In this way, such a locking mechanism can be fully integrated in the connector.
- a method for controlling a locking mechanism of the connector unit described comprises the following method steps: (S1) detecting information on a first connector that is to be mated with a second connector, the information on the first connector being read by an identification device of the second connector from an identification element of the first connector can be read the; (S2) Comparing the information read out in this way with data previously stored in a controller for the second plug connection and adjusting and/or rotating the locking mechanism from a blocking position into an unlocking position in relation to a locking axis by means of a drive unit if the comparison involves releasing the first plug connector for mating with the second connector, or leaving the locking mechanism in the blocked position if the comparison has not revealed a release of the first connector for mating with the second connector.
- the specific geometry of the through-opening of the locking head is an outer contour of the locking head
- the specific geometry of the through-opening of the receptacle is an inner contour of the through-opening of the receptacle.
- a particular advantage results from the mechanical coding of the locking mechanism through different geometries of the locking head (similar to a key) to mechanically avoid impermissible combinations.
- a further embodiment provides that a receiving shaft with the receptacle is mounted in a bearing housing in which one of the two locking assemblies can be adjusted and/or rotated with respect to a locking axis.
- a wave is advantageously easy to store in a housing.
- the housing can consist of two parts that are connected by latching. This advantageously reduces installation space and assembly time.
- the take-up shaft interacts with the take-up with a drive unit which is coupled to the take-up shaft. In this way, blocking and unlocking can advantageously be automated.
- take-up shaft is coupled to the drive unit via a gear train.
- Transmissions of this type are available on the market at low cost and with high quality.
- different drive units can be adapted to the mechanics in this way.
- the drive unit can be an electromotive, electromagnetic or pneumatic drive unit. These drives are also available on the market at low cost and with high quality.
- the receiving shaft can be adjustable and/or rotatable with respect to its locking axis using a tool.
- the latching head can also be adjustable and/or rotatable in relation to a locking axis by means of a tool. This is advantageous because in this way either the receiving shaft or the locking head can be reached for emergency actuation, depending on the installation position.
- the locking head is connected to a stub shaft, which is mounted in a bearing housing of the other of the two locking assemblies so that it can be adjusted and/or rotated.
- a stub shaft which is mounted in a bearing housing of the other of the two locking assemblies so that it can be adjusted and/or rotated.
- the latching head alone or in connection with the stub shaft is arranged in the associated housing so that it can be adjusted and/or rotated in a sluggish manner in order to prevent unwanted adjustment and/or rotation from taking place. Adjustment and/or twisting is therefore only possible with a suitable tool. borrowed. An additional braking element is also conceivable, which is released with the tool in the event of an emergency operation.
- the locking mechanism has an identification device and at least one identification element, the identification device being arranged in one locking assembly and the at least one identification element being arranged in the other locking assembly. This results in the advantage that automatic control can be made possible.
- the locking mechanism has a display device for a status of a plug connector, since in this way there are clear signs that failed attempts to connect actions can be avoided.
- a further embodiment provides that the locking mechanism has a central and/or decentralized control of the drive unit, the identification device and the display device. This achieves an advantageous release via the electrical control element/the (de-)central control intelligence.
- the plug connection unit can have a detection device which detects the position of a plug connector that has been inserted sufficiently deeply. This increases the security of the plug-in connection unit.
- a display device on the second connector indicates that mating of the first connector with the second connector is possible if the comparison means that the first connector is released for mating with the second connector has resulted, or that mating the first connector with the second connector is not possible if the comparison has not resulted in a release of the first connector for mating with the second connector.
- Yet another embodiment of the method provides that in method step (S3) the position of a sufficiently deeply inserted connector is detected before the locking mechanism is adjusted and/or rotated the unlocking position takes place in the blocking position in relation to the locking axis by means of the drive unit. This is advantageous for automating the locking process.

- a recess 5f which is formed coaxially to the bore 5g in the wall with the end face 5e of the bearing housing 5, 5a, has a diameter that is larger than the imaginary longitudinal axis of the bottom section 6f of the locking head 6a and with the outer diameter of the receptacle 9a the take-up shaft 9 corresponds.
- an end area of the receptacle 9a is arranged with the plate section 10 in the recess 5f (FIG. 5).
- the receptacle 9a of the receptacle shaft 9 is rotated about the locking axis 7' such that the locking head 6a of the key shaft 6 cannot be inserted into the receptacle 9a through the through-opening 10a of the plate section 10.
- the imaginary longitudinal axis of the slot of the through-opening 10a is pivoted by 90° about the locking axis T in relation to the imaginary longitudinal axis of the locking head 6a. In other words, in the locking position there is no overlap between the inner contour of the through opening 10a and the outer contour of the locking head 6a.
- the receptacle 9a of the receiving shaft 9 is rotated about the locking axis 7' in such a way that the locking head 6a of the key shaft 6 can be inserted into the receptacle 9a through the through-opening 10a of the plate section 10.
- the imaginary longitudinal axis of the slot in the through-opening 10a is pivoted parallel to the imaginary longitudinal axis of the latching head 6a. In other words, the inner contour of the through opening 10a and the outer contour of the latching head 6a coincide.
- the first connector 2 and the second connector 3 are plugged together.
- the locking head 6a of the key shaft 6 is accommodated in the interior space 9d of the receptacle 9a of the receptacle shaft 9.
- the end section of the receptacle 9a with the plate section 10 is arranged in the recess 5f of the end face 5e of the bearing housing 5, 5a.
- the plate section 10 is arranged between the underside 6i of the locking head 6a (FIG. 4) and a wall of the bearing housing 5, 5a, in which the bore 5g for the key shaft 6 is formed.
- the receptacle 9a with the receptacle shaft 9 is rotated again by 90° with respect to the latching head 6a by means of the drive unit 14 twisted into a blocking position.
- the through opening 10a, designed as a slot, of the plate section 10 of the receptacle 9a also rotates between the bottom side 6i of the locking head 6a and the bearing housing 5, 5a in the recess 5f.
- the imaginary longitudinal axes of the through opening 10a of the plate section 10 of the receptacle 9a and of the base section 6f of the locking head 6a no longer run parallel but at right angles to one another. This means that the first connector 2 can no longer be pulled out of the second connector 3 .
- the connector binding unit 1 is locked.
- a further locking security of the plug-in connection unit 1 is given by the locking clip 3d in cooperation with the bolts 2e.
- a hub of the drive toothing 13b has a receptacle 13c for a tool 17' (FIG. 5).
- the receptacle 13c can be a hexagon socket, for example.
- Emergency unlocking or emergency locking of the locking mechanism 4 is possible with the tool 17', in that the receiving shaft 9 can be rotated with the tool 17'.
- a further emergency unlocking or an emergency locking of the locking mechanism 4 is also possible in that the tool 17 can be used to turn the key shaft 6 with the locking head 6a.
- the locking mechanism 4 of the connector unit 1 is also equipped with an identification device 16, which is shown only symbolically in FIG.
- the identification device 16 is assigned here to the second locking assembly 4'a and has an antenna which interacts with an identification element 16a, which is not shown but is easy to imagine, of the first locking assembly 4a.
- the identification element 16a is installed in the latching head 6a of the key shaft 6 here only by way of example (FIG. 4). It can also be arranged at another location of the first locking assembly 4a, for example in the bearing housing 5, 5a.
- the identification element 16a is an RFID module, for example, in which information about the first connector 2 is stored.
- the identification device 16 enters into wireless communication with the identification element 16a when the first connector 2 comes close to the second connector 3 for an intended insertion process. Then the information of the identification element 16a is read out by the identification device 16 and a check is made as to whether the first connector 2 is intended or suitable for mating with the second connector 3 .
- the second locking assembly 4'a is moved from a previous blocking position, in which mating of the first connector 2 to the second connector 3 is not possible, by a controller using the drive unit 14 to the unlocked position as described above misaligned.
- the first connector 2 can now be plugged into the second connector 3 .
- a further detection device which is not shown but is conceivable, for example a limit switch.
- Guide devices F, F′ (FIG. 1) that are not explained further here can be used for this purpose.
- the drive unit 14 is then prompted by the controller to reset the second locking assembly 4'a from the unlocked position back into the blocking position as described above. In this way, the assembled plug-in connection unit 1 is secured against a separation of the first plug-in connector 2 from the second plug-in connector 3 .
- the control, the identification device 16 and the drive unit 14 can be supplied with electrical energy in different ways by electrical supply lines in the second plug connector 3 .
- Rechargeable electrical power storage devices are also possible.
- Inductively transmitted electrical supply energy is also conceivable.
- the controller can, for example, have a microcomputer in the plug-in connection unit 1, e.g. in the second plug-in connector 3, for example integrated in the drive unit 14. It is also possible for the controller to be arranged decentrally as part of a higher-level control device, in which case the microcomputer in the plug-in connection unit 1 can be connected to the higher-level control device.
- a display device 11 , 12 is provided for quick identification of the position of the locking mechanism 4 or the second locking assembly 4 ′ a in the second connector 3 .
- the two display devices 11, 12 are installed in an end face 8d of the bearing housing 8, 8a of the second locking assembly 4'a. These can be designed as red and green LEDs, for example. When the green LED lights up, it indicates the unlocked position for plugging the first connector 2 into the second connector 3 if the previous check by means of the identification device 16 resulted in a release. If such a release is not present, the red LED lights up and indicates the blocked position. a collision It is not possible to bend, since the second locking assembly 4'a prevents plugging together due to its blocking position.
- FIG. 6 shows a schematic flow diagram of an exemplary embodiment of a method according to the invention for controlling a locking mechanism 4 of a plug connection unit 1.
- a first method step S1 information about a first connector 2 that is to be plugged into a second connector 3 is recorded.
- the information of the first connector 2 is read out by the identification device 16 of the second connector 3 from an identification element 16a of the first connector 2 .
- the information read out in this way is compared with data previously stored in a controller for the second plug connection 3 in a second method step S2. Based on this comparison, a decision is made as to whether the first connector 2 intended for mating may be connected to the second connector 3 . If plugging can be made possible in this way, the locking mechanism 4, i.e. here the second locking assembly 4'a, is moved and/or rotated from a blocking position to an unlocking position, with the drive unit 14 being used to loosen the receiving shaft 9 with the receptacle 9a the blocking position in the unlocking position about the locking axis 7 'is adjusted and / or rotated. If the comparison does not result in a release for mating, the locking mechanism 4, i.e. here the receptacle 9a, remains in the blocked position.
- a third method step S3 the locking mechanism is moved and/or rotated from the unlocked position into the blocked position.
- step S3 the position of a sufficiently deeply inserted connector 2, 3 is also detected before the locking mechanism 4, i.e. the receiving shaft 9 with the receptacle 9a, is adjusted and/or rotated from the unlocked position to the blocked position in relation to the locking axis takes place by means of the drive unit 14.
- the locking mechanism ie here the locking assembly 4'a of the second connector 3
- the locking assembly 4'a of the second connector 3 is automatically placed back into the blocking position, causing an erroneous ches mating with other connectors that have no identification element 16a, for example, is prevented.
- the first connector 2 can also have a motorized drive unit, which adjusts the latching head 6a. In this way, combined adjustment movements and/or twisting movements of receptacle 9a and latching head 6a can be implemented.
