Description

Technical field

[0001] The present invention relates to a locking device with a recognition feature (primary recognition feature) as part of a second recognition feature (secondary recognition feature). The locking device serves to secure the locking of a locking element or for "connector position control" or "connector position assurance (CPA)" and can be used to secure the locking of a connector housing to a mating connector housing. In particular, the invention relates to a CPA with a detectable sub-element. State of the art

[0002] Connector Position Assurance (CPA) devices are designed to prevent a connector housing that is locked onto its mating connector housing from unintentionally detaching from the mating connector housing. This detachment can occur, for example, due to vibrations, temperature-related expansion or contraction, pulling on a cable housed within the connector housing, or other mechanical impacts. The CPA is responsible for locking the connector to its mating component as the final actuation element. To ensure secure locking, the final locking state must be recorded by a scannable element, and this element must only be readable when the CPA is fully closed. Description of the invention

[0003] One object of the invention is therefore to create a suitable device with which it can be reliably detected whether a locking mechanism is present or not, in particular for connectors where a CPA locking mechanism is required.

[0004] The problem is solved by the subject matter of the independent claims. Advantageous embodiments of the invention are specified in the dependent claims, the description, and the accompanying figures.

[0005] Due to the requirement for a high degree of automation in the manufacturing and assembly of the connector, the use of a scannable element as a control function is essential. The invention presented here relates to a safety device comprising a display element with a recognition feature and a contrast element, wherein the contrast of the recognition feature is modified by the contrast element, and the display element can thus be used as a scannable element to ensure reliable control of the connector manufacturing process and to enable scanning of the connector system in its assembled state. The solution presented here can be applied to various connector systems and can be easily adapted from one connector system to another.

[0006] The main feature of the inventive solution is a detectable element located on the CPA (Controlled Physical Approach) that can be detected after the CPA is actuated. Furthermore, this element cannot be detected when the CPA is in the open position because it is either a sub-element of another detectable element or its contours are manipulated.

[0007] According to a first aspect, the problem described above is solved by a locking device for securing the locking of a locking element, wherein the locking device comprises: a locking element that is movable from a first locking position to a second locking position, wherein the locking element effects a locking in the second locking position; an indicator element with a recognition feature for displaying information; wherein, in the first locking position of the locking element, the recognition feature is part of a second recognition feature, so that the recognition feature is not separately recognizable; and wherein, in the second locking position of the locking element, the recognition feature is not part of the second recognition feature, so that the recognition feature is separately recognizable.

[0008] The first identifying feature is also referred to here as the primary identifying feature, and the second identifying feature as the secondary identifying feature.

[0009] The information can represent any type of information. Specifically, it concerns information regarding whether the locking element is engaged or disengaged. Additionally, the information can include further details, such as user information, the serial number of the locking device or individual components of the device, user instructions, etc.

[0010] Such a locking device offers the technical advantage of enabling reliable and secure detection of a locking position. The indicator element with the recognition feature can be scanned, allowing for reliable automatic detection of the information and thus the position of the locking element. This makes it possible, in particular, to automatically detect the status of connectors requiring a CPA locking mechanism. The locking device therefore meets the requirements for a CPA locking mechanism.

[0011] The identifying feature can be, for example, a code, such as a one- or multi-dimensional code, or a pictogram or a symbol.

[0012] According to an exemplary embodiment of the locking device, the identifying feature is not concealed in either locking position of the locking element and remains visible at all times.

[0013] This offers the technical advantage that it is not necessary to cover the display element with the recognition feature to achieve the desired effect of non-recognizability. The modification of the recognition feature by making it part of a second recognition feature is sufficient to render it unrecognizable, so that it can no longer be separately detected or recognized by a scannable element. The scannable element can then only detect the second recognition feature, but not the recognition feature as a separate entity.

[0014] According to an exemplary embodiment of the locking device, when the locking element is moved from the first locking position to the second locking position, the recognition feature is pushed out of the second recognition feature, so that the recognition feature is separately recognizable in the second locking position.

[0015] This offers the technical advantage that the detectability of the recognition feature can be easily controlled by actuating the locking element. When the locking element is actuated by moving it into the second locking position, the recognition feature moves out of the second recognition feature and can be recognized as a separate feature that is no longer part of the second recognition feature, so that the presence of a locking effect can be reliably detected.

[0016] According to an exemplary embodiment of the locking device, the second detection feature completely or at least partially surrounds the detection feature in the first locking position.

[0017] This offers the technical advantage that the identifying feature can no longer be recognized as a separate feature, thus reliably concluding that the locking element is in the first locking position, i.e., that no locking is present. Even an extension of the edge of the identifying feature is sufficient to render it indistinguishable from the outside.

[0018] According to an exemplary embodiment of the locking device, the recognition feature has contours that delimit the recognition feature from its surroundings; wherein in the first locking position the contours of the recognition feature are obscured or rendered unrecognizable by the second recognition feature; and wherein in the second locking position the contours of the recognition feature are not obscured or rendered unrecognizable by the second recognition feature.

[0019] This offers the technical advantage that obscuring the contours of the recognition feature means that it is no longer separately recognizable, thus making it possible to distinguish between the states "locking" and "unlocking".

[0020] According to an exemplary embodiment of the security device, the recognition feature comprises a code, for example a one- or multi-dimensional code; and the second recognition feature comprises a second code, for example a second one- or multi-dimensional code; wherein the code is not recognizable if it is part of the second code.

[0021] This offers the technical advantage that differentiation based on codes can be easily achieved. Suitable codes, such as 1D, 2D, or 3D codes, exhibit strong contrast, making them easy to read by a sensor.

[0022] According to an exemplary embodiment of the security device, the identification feature comprises a one-dimensional or multi-dimensional code, for example a Data Matrix code, DMC, a QR code, or a barcode.

[0023] The Data Matrix code is one of the best-known 2D codes and can be used for permanent and robust direct marking. The DMC is variable in size, thus allowing for a wide variety of symbol elements. QR codes and barcodes are also suitable as identification features or secondary identification features.

[0024] According to an exemplary embodiment of the security device, the identifying feature is recognizable if it is not part of the second identifying feature.

[0025] This offers the technical advantage that the state of the locking element can be reliably and safely detected, for example, using a reader or scanner. This allows for efficient control of automated assembly of plug-in systems.

[0026] According to an exemplary embodiment of the locking device, the locking device is designed to provide a plug position locking (CPA) to secure a locking of a plug housing to a mating plug housing.

[0027] This offers the technical advantage that the state of the CPA can be reliably recorded by a scannable element, which is only readable when the CPA is finally closed.

[0028] According to an exemplary embodiment of the locking device, the locking device further comprises: a clamping element for clamping the plug housing into the mating plug housing, wherein the clamping element is movable from an open clamping element position, in which the plug housing can be inserted into the mating plug housing, to a closed clamping element position, in which the plug housing is electrically connected to the mating plug housing; wherein the locking element is attached to the clamping element and is configured to lock or unlock the clamping element. As already described above, the indicator element displays information, for example, information about the clamping element being locked by the locking element.

[0029] This offers the technical advantage that the display element reliably shows information, for example information regarding the locking of the clamping element, such as a clamp, so that the state of the clamping element can be reliably detected, for example with a scannable element.

[0030] According to an exemplary embodiment of the locking device, the locking element is movable from the first locking position to the second locking position in the closed clamping element position and is designed to lock the clamping element in the closed clamping element position in the second locking position and to unlock the clamping element for movement into the open clamping element position in the first locking position.

[0031] This offers the technical advantage of ensuring a secure connection between the plug housing and the mating plug housing via the clamping element. The locking device thus meets the requirements for a CPA locking mechanism.

[0032] According to an exemplary embodiment of the locking device, the first detection feature and the second detection feature are attached to the clamping element; and a movement of the locking element from the first locking position to the second locking position pushes the first detection feature out of the second detection feature, so that the second detection feature is separately identifiable in the second locking position.

[0033] This offers the technical advantage that the indicator element can reliably and robustly display information, such as information regarding a locking status. In the first locking position, the detection feature is enclosed by a second detection feature, so it cannot be detected separately and no information (e.g., information about a locking status) can be recognized. In the second locking position, the detection feature is no longer enclosed by the second detection feature, so it can be detected separately, for example, with a scannable element or even by the user's eyes.

[0034] According to a second aspect, the task described above is solved by a plug connection with a plug housing and a mating plug housing, which are connected and secured to each other via a locking device according to the first aspect.

[0035] According to a third aspect, the task described above is solved by a security system comprising a security device according to the first aspect and a reader, wherein the reader is configured to detect the recognition feature of the indicator element when the locking element is in the second locking position in order to recognize information, for example, information about a locking.

[0036] According to an exemplary embodiment of the security system, the reader is designed to detect the identifying feature of the indicator element only when the locking element is in the second locking position and to detect a correct locking only in this position. Brief character description

[0041] Fig. 1shows a schematic representation of the states of a safety device 100 according to the invention.

[0042] The locking device 100 serves to secure a locking element 110. The locking device 100 comprises a locking element 110 and an indicator element 120 with a recognition feature 200 (see also Figures 2a and 2b as well as 3a and 3b).

[0043] The locking element 110 can be moved from a first locking position 111 to a second locking position 112 and causes a locking in the second locking position 112.

[0044] The display element 120 with the identification feature 200 (see Figures 2a and 2b as well as 3a and 3b) serves to display information, for example information about a locking by the locking element 110.

[0045] In the first locking position 111 of the locking element 110, the recognition feature 200 is part of a second recognition feature 212, so that the recognition feature 200 is not separately recognizable.

[0046] In the second locking position 112 of the locking element 110, the identification feature 200 is not part of the second identification feature 212, so that the identification feature 200 is separately identifiable (see also Figures 2a and 2b as well as 3a and 3b).

[0047] The identifying feature 200 is not obscured in either locking position 111, 112 of the locking element 110 and remains visible at all times, as described in more detail below. Figures 2a and 2b or 3a and 3b depicted.

[0048] An exemplary implementation of the identifying feature 200 and the second identifying feature 212 is shown in the Figures 2a and 2b as well as 3a and 3b are presented and described in more detail.

[0049] The Figures 2a and 2bFigures 100 show representations of a locking device according to the invention in an exemplary embodiment in the first locking position ( Figure 2a ), in which the recognition feature 200 is part of a second recognition feature 212, and in the second locking position ( Figure 2b ), in which the identifier 200 is not part of the second identifier 212.

[0050] The safety device 100 in Figure 2a and Figure 2b corresponds to the above. Figure 1 described safety device, wherein in Figure 2a and Figure 2b The structure of this safety device is shown in more detail in 100.

[0051] As already mentioned above Figure 1 As described, the locking device 100 serves to secure a locking element 110. The locking device 100 comprises a locking element 110 and an indicator element 120 with a recognition feature 200 as well as a second recognition feature 212, as described in the Figures 2a and 2b depicted.

[0052] The locking element 110 can be moved from a first locking position 111 to a second locking position 112 and effects a locking action in the second locking position 112. Figure 2a The locking element 110 is shown in the first locking position 111, in Figure 2b in the second locking position 112.

[0053] The display element 120 with the identification feature 200 (see Figures 2a and 2b ) serves to display information, for example, information about locking by the locking element 110. In the Figures 2a and 2b The identifying feature is represented as a two-dimensional code with white and black elements or pixels. The 2D code is, for example, a DMC.

[0054] As already mentioned above Figure 1The identification feature 200 in the first locking position 111 of the locking element 110 is described as being part of a second identification feature 212, so that the identification feature 200 is not separately identifiable.

[0055] In the second locking position 112 of the locking element 110, the recognition feature 200 is not part of the second recognition feature 212, so that the recognition feature 200 is separately recognizable.

[0056] The identifying feature 200 is not covered in either locking position 111, 112 of the locking element 110 and remains visible at all times.

[0057] When moving the locking element 110 from the first locking position 111 (see Figure 2a ) into the second locking position 112 (see Figure 2b ) the recognition feature 200 is pushed out of the second recognition feature 212, so that the recognition feature 200 is in the second locking position 112 (see Figure 2b) is separately identifiable.

[0058] As from Figure 2a As can be seen, in the first locking position 111, the second recognition feature 212 completely surrounds the recognition feature 200. Alternatively, it can also partially surround the recognition feature 200, for example only on one side or at a corner.

[0059] The identifying feature 200 has contours that delineate it from its surroundings. In the first locking position 111, the contours of the identifying feature 200 are obscured by the second identifying feature 212 (see Figure 2a In the second locking position 112, the contours of the recognition feature 200 are not obscured by the second recognition feature 212 (see Figure 2b ), because it has been pushed out of the second identifying feature 212 and its contours have thus become recognizable.

[0060] In the example of the Figures 2a and 2bThe identifying feature 200 comprises a code, for example, a two-dimensional code as shown in the figures. The second identifying feature 212 comprises a second code, for example, a second two-dimensional code as shown in the figures, which may be different from the two-dimensional code of identifying feature 200. The two-dimensional code is not detectable if it is part of the second two-dimensional code, as shown in Figure 2a depicted.

[0061] As in the example of the Figures 2a and 2b To illustrate, the identifier 200 or the 2D code 200 can comprise a Data Matrix code (DMC). It could also be a barcode, for example.

[0062] A Data Matrix code like this consists of, for example, the following main components: 1) Two pairs of solid and broken edges as boundary lines (finder pattern or position markers). The solid boundary lines serve as delimiters. They are used for aligning and correcting the Data Matrix code, allowing for reading from any angle. 2) A surrounding quiet zone. This empty zone surrounds the Data Matrix code. It contains no information or patterns. The width of the quiet zone is at least one column or one row (ideally four times the width or height of a module) and is required to separate it from other surrounding visual elements. 3) The corner opposite the closed edges. This corner allows for quick identification of the code scheme. In the ECC 200 code scheme with an even number of rows and columns, the element in the upper right corner is always white.In other standardized code schemes with an odd number of rows and columns, the element in the upper right corner is always black. 4) The alignment patterns. This paired combination of solid and broken lines in both horizontal and vertical directions facilitates image analysis. They divide large data fields into equal parts in codes with at least 32 modules of edge length. 5) The data area. This data area contains the actual binary information in coded form. The size of the matrix also defines the number of possible pieces of information.

[0063] The identifier 200, the 2D code, or the DMC can be identified, for example read with a reader, if it is not part of the second identifier 212, the second 2D code, or the second DMC.

[0064] The locking device 100 can be configured to provide a plug position locking (CPA) for securing a locking of a plug housing 400 to a mating plug housing 401, as shown below. Figure 4 described in more detail.

[0065] The following is an example using CPA, where the identifier 200 is a DMC that includes black and white pixels, as in the Figures 2a and 2b depicted.

[0066] The element to be detected, i.e., the identifying feature 200, in the Figures 2a and 2bRepresented as DMC, it is always located on the CPA and is always fully visible. However, this element 200, in the first locking position 111 or position 1, is a sub-element of a larger element to be detected, i.e., the second detection feature 212, or, because it is a sub-element, it cannot be detected. Only the larger element (the second detectable element 212) can be detected in position 1, if desired, and represents, for example, the status "open".

[0067] After activating the CPA, in the second locking position 112 or position 2 only the DMC 200 can be scanned on the CPA, since the DMC as a sub-element can also be scanned on its own.

[0068] With the safety device 100, as above to the Figure 1 and 2a and 2bAs described above, a safety system can be implemented using a reader that can reliably determine the state of the locking element 110 and transmit it to a controller for further processing. Such a safety system comprises a safety device 100 as described above and a reader. The reader is configured to detect the detection feature 200 of the indicator element 120 when the locking element 110 is in the second locking position, i.e., when the detection feature 200 is not part of the second detection feature 212, in order to detect a locking state.

[0069] The reading device can be configured to detect the detection feature 200 only when the locking element 110 is in the second locking position 112 and to detect a correct locking only in this position 112.

[0070] The reader can transmit the captured information, such as the read 2D code or DMC, to a controller which can then display an error in case of faulty capture and perform appropriate steps to control the manufacturing or packaging process.

[0071] The Figures 3a and 3b show a representation of a further embodiment in which the recognition feature 200 in the first locking position 111 is part of a second recognition feature 212 ( Fig. 3a ) and where the identifying feature 200 in the second locking position 112 is not part of the second identifying feature 212 ( Fig. 3b ).

[0072] The Figures 3a and 3b They demonstrate the same principle as above regarding the Figures 2a and 2b presented as an alternative concept.

[0073] Here, circle 200, which corresponds to the identification feature 200, is located on the CPA and is in position 1, 111 (see Figure 3a) Partial element of a quadrilateral that corresponds to the second identifying feature 212. The circle 200 is in position 1, 111 ( Figure 3a ) not scannable, as it is part of a quadrilateral, i.e., part or component of the second recognition element 212. In position 2, 112 (see Figure 3b ) it is detectable because the contours are clearly visible.

[0074] The Figures 4a and 4b Figure 1 shows 3D representations of a locking device 100 comprising a locking element 110, an indicator element 120 with a recognition feature 200, and a clamping element 300 in the closed clamping bracket position. The locking element 110 is in Figure 4a in the first locking position 111 and in Figure 4b in the second locking position 112. The locking element 110 can be moved between the two locking positions 111, 112.

[0075] The locking device 100 is designed to provide a plug position locking (CPA) to secure a locking of a plug housing 400 on a mating plug housing 401.

[0076] The locking device 100 includes, in addition to the locking element 110 and indicator element 120 with recognition feature 200 and second recognition feature 212 already described above, a clamping element 300, for example a clamping bracket, for clamping the plug housing 400 into the mating plug housing 401.

[0077] The clamping element 300 can be moved from an open clamping element position, in which the plug housing 400 can be inserted into the mating plug housing 401, to a closed clamping element position, in which the plug housing 400 is electrically contacted and fixed to the mating plug housing 401.

[0078] The locking element 110 is attached to the clamping element 300, as shown in the Figures 4a and 4billustrated, for example on a panel at the clamping element 300, as shown in the Figures 4a and 4b shown, and is designed to lock or unlock the clamping element 300.

[0079] The identification feature 200 of the display element 120 indicates information, for example, information about the locking of the clamping element 300 by the locking element 110. The identification feature 200 of the display element 120 is in the Figures 4a and 4b based on the already to the Figures 3a and 3b The described circle is shown as an example. Of course, it can also exist in other forms, for example as code as above. Figures 2a and 2b described.

[0080] The locking element 110 is in the closed clamping element position from the first locking position 111 (see Figure 4a ) into the second locking position 112 (see Figure 4a) movable. The locking element 110 is designed to lock the clamping element 300 in the closed clamping element position in the second locking position 112, and to unlock the clamping element 300 for movement into the open clamping element position in the first locking position 111. In Figure 4a An intermediate position of the clamping bracket 300 is shown; the locking element 110 is thus in the open, non-locked first locking position 111.

[0081] The display element 120 with the identification feature 200 is attached to the clamping element 300, for example to a panel on the clamping element 300, as in the Figures 4a and 4b Furthermore, the second identifying feature 212 is also attached to the clamping element 300, as shown in the Figures 4a and 4b depicted.

[0082] When the locking element 110 moves from the first locking position 111 to the second locking position 112, the recognition feature 200 is pushed or moved out of the second recognition feature 212, so that the recognition feature 200 is separately recognizable in the second locking position 112 (see Figure 4b ).

[0083] The Figures 4a and 4b They also show a plug connection with a plug housing 400 and a mating plug housing 401, which are connected and secured to each other via the locking device 100 as described above. REFERENCE MARK LIST
