It goes without saying that other examples can be used and structural or logical changes can be made without departing from the concept of the present disclosure.

[0055] FIG. 1 shows a schematic illustration of the states of a securing device 100 according to the present disclosure.

[0056] The securing device 100 serves to secure the locking of a locking element 110. The securing device 100 includes a locking element 110, an indicator element 120 having an identifying feature 200 (see also FIGS. 2A and 2B), and a contrasting element 212 having a contrasting surface 213.

[0057] The locking element 110 can be moved from a first locking position 111 into a second locking position 112 and produces locking in the second locking position 112.

[0058] The indicator element 120 having the identifying feature 200 (see FIGS. 2A and 2B) serves to indicate an item of information, for example an item of information about the locking by the locking element 110. However, it is also possible to indicate any other type of information. Whether the item of information is indicated or not indicated is desired for discerning the locking state.

[0059] The contrasting surface 213 of the contrasting element 212 forms a contrast in relation to the identifying feature 200, with the result that the identifying feature 200 is discernible when the identifying feature 200 is placed above the contrasting surface 213 and is not discernible when the identifying feature 200 is not placed above the contrasting surface 213.

[0060] In this case, in the first locking position 111 of the locking element 110, the identifying feature is not placed above the contrasting surface 213 and therefore is not discernible. In the second locking position 112 of the locking element 110, by contrast, the identifying feature 200 is placed above the contrasting surface 213 and therefore is discernible.

[0061] In both of the locking positions 111, 112 of the locking element 110, the identifying feature 200 is not concealed and always remains visible, as set out in more detail below in relation to FIGS. 2A and 2B.

[0062] An example of the identifying feature 200 and of the contrasting element 212 is illustrated and described in more detail in FIGS. 2A and 2B.

[0063] FIGS. 2A and 2B show illustrations of a securing device 100 according to the present disclosure as per an example in the first locking position (FIG. 2A), in which the contrasting surface 213 is not underneath the identifying feature 200, and in the second locking position (FIG. 2B), in which the contrasting surface 213 is underneath the identifying feature 200.

[0064] The securing device 100 in FIG. 2A and FIG. 2B corresponds to the securing device described above in relation to FIG. 1, with FIG. 2A and FIG. 2B illustrating the structure of this securing device 100 in more detail.

[0065] As already described above in relation to FIG. 1, the securing device 100 serves to secure the locking of a locking element 110. The securing device 100 includes a locking element 110, an indicator element 120 having an identifying feature, and a contrasting element 212, as illustrated in FIGS. 2A and 2B.

[0066] The locking element 110 can be moved from a first locking position 111 into a second locking position 112 and produces locking in the second locking position 112. FIG. 2A illustrates the locking element 110 in the first locking position 111; FIG. 2B illustrates the locking element in the second locking position 112.

[0067] The indicator element 120 having the identifying feature 200 (see FIGS. 2A and 2B) serves to indicate an item of information, for example an item of information regarding locking or non-locking by the locking element 110, or any other type of information. FIGS. 2A and 2B illustrate the identifying feature as a two-dimensional code with white and black elements or pixels. The 2D code is, for example, a DMC.

[0068] The contrasting surface 213 of the contrasting element 212 forms a contrast in relation to the identifying feature 200, with the result that the identifying feature 200 is discernible when the identifying feature 200 is placed above the contrasting surface 213 and is not discernible when the identifying feature 200 is not placed above the contrasting surface 213.

[0069] In this case, in the first locking position 111 of the locking element 110 (see FIG. 2A), the identifying feature 200 is not placed above the contrasting surface 213, but to the right of the contrasting surface 213, and therefore is not discernible. In the second locking position 112 of the locking element 110, by contrast, the identifying feature 200 is placed above the contrasting surface 213 and therefore is discernible.

[0070] In both of the locking positions 111, 112 of the locking element 110, the identifying feature 200 is not concealed and always remains visible, as shown in FIGS. 2A and 2B.

[0071] The indicator element 120 has a transparent surface 214, to which the identifying feature 200, in this case the 2D code, is applied. In the second locking position 112 of the locking element 110, the transparent surface 214 with the identifying feature 200 or the 2D code is placed above the contrasting surface 213, with the result that the identifying feature 200 is discernible, as shown in FIG. 2B.

[0072] As illustrated in FIG. 2A, in the first locking position 111 of the locking element 110, the indicator element 120 having the identifying feature 200, in this case the 2D code, is placed above a contrast-lowering surface 215, which inhibits the identifying feature 200 from being discerned. The contrast-lowering surface 215 may be, for example, a dark surface or a black surface, so that the identifying feature 200 or the 2D code above this dark surface does not form enough contrast to be discerned. The contrast-lowering surface 215 lowers the contrast or reduces the contrast to a great enough extent that the identifying feature 200 is no longer discernible.

[0073] When the locking element 110 is being moved from the first locking position 111 into the second locking position 112, the contrasting surface 213 (in the example here, the white surface 213) of the contrasting element 212 is caused to move or slide between the contrast-lowering surface 215 (in the example here, the black surface 215) and the identifying feature 200, with the result that the identifying feature 200 is discernible in the second locking position 112 (see FIG. 2B).

[0074] The identifying feature 200 may include, for example, a code with elements in a first color (for example a light color, such as white in this example) and elements in a second color (for example a dark color, such as black in this example). The elements in the first color (e.g. white) are not discernible when the identifying feature 200 or code is placed above the contrast-lowering surface 215 (in this example the black surface).

[0075] However, both the elements in the first color and the elements in the second color of the identifying feature 200 or code are discernible when the contrasting surface 213 is between the contrast-lowering surface 215 and the identifying feature 200 or two-dimensional code (see FIG. 2B).

[0076] As depicted in the example of FIGS. 2A and 2B, the identifying feature 200 or the code may include a data matrix code, DMC. The identifying feature 200 may, for example, also be a barcode or a QR code or a pictogram or any desired symbol.

[0077] Such a data matrix code includes or consists, for example, of the following main components: [0078] 1) two pairs of solid continuous edges and interrupted edges as boundary lines (finder pattern or position marker). The solid boundary lines serve for delimitation. They are used to align and equalize the data matrix code, so that any reading angle is possible. [0079] 2) a peripheral quiet zone. This empty zone surrounds the data matrix code. It does not contain any information or patterns. The width of the quiet zone is at least one gap or line (in one example four times the width, or height, of a module) and is desired for delimitation from other optical image elements of the surrounding area. [0080] 3) the corner situated opposite the closed edges. This corner makes it possible to quickly discern the code schemata. In the case of the identifying feature 200 with code scheme ECC, with an even number of lines and gaps, the element in the upper right-hand corner is white. In the case of the other standardized code schemata, with an odd number of lines and gaps, the element in the upper right-hand corner is black. [0081] 4) the alignment pattern. This combination in pairs of continuous and interrupted lines in both directions, horizontally and vertically, makes it easier to evaluate the image. They subdivide large data fields into equally sized parts in the case of codes with an edge length of at least 32 modules. [0082] 5) the data area. This data area contains the actual binary information in coded form. Depending on the size of the matrix, the number of possible items of information is also defined in this way.

[0083] The identifying feature 200, or the code or the DMC, is discernible and can be read, for example by means of a reader or visually by a user, when it is above the contrasting surface 213.

[0084] The securing device 100 may be designed to perform connector position assurance (CPA) to secure the locking of a connector housing 400 to a mating connector housing 401, as described in more detail below in relation to FIGS. 3A to 3D.

[0085] An example with a CPA system in which the identifying feature 200 is a DMC including black and white pixels, as illustrated in FIGS. 2A and 2B, will be described below. The identifying feature 200 or DMC is only readable when the CPA system is slid underneath it.

[0086] The contours of the identifying feature 200 or DMC, which are black in this case, are represented on the transparent surface 214. Since the plane (referred to here as contrast-lowering surface 215) underneath the transparent surface 214 has the same color as the contours of the identifying feature 200 or DMC, the latter is not discernible (see FIG. 2A). There is a white element (here referred to as contrasting surface 213) on the CPA system. It may also have a different color; all that is important is that the contrast in the end position is high enough. By actuating the CPA system, the identifying feature 200 or DMC can be detected in the end position (here referred to as second locking position 112) (see FIG. 2B). The identifying feature 200 or DMC is always visible in this example, that is the identifying feature 200 it is not concealed. The detectability is controlled via the contrast.

[0087] The securing device 100, as described above in relation to FIGS. 1 to 2B, and a reader make it possible to implement a securing system which can reliably determine the state of the locking element 110 and transfer this state, for example to a controller, for further processing. Such a securing system includes a securing device 100 as described above and a reader. The reader is designed to detect the identifying feature 200 of the indicator element 120 when the locking element 110 is in the second locking position 112, i.e. when the identifying feature 200 of the indicator element 120 is detectable, in order to thus discern an item of information and therefore locking.

[0088] The reader may be designed to detect the identifying feature 200 only when the locking element 110 is in the second locking position 112 and to detect correct locking only in the second locking position 112.

[0089] The reader may forward the detected information, for example the read-out 2D code or DMC, to a controller, which then can indicate a fault if the reader detects one and take corresponding steps to control the production or fabrication process.

[0090] FIGS. 3A, 3B, 3C and 3D show perspective and plan or top views of a securing device 100 including a locking element 110, an indicator element 120 having an identifying feature, a contrasting element 212, and a clamping element 300 in a closed or open clamping-clip position. The locking element 110 can be moved from the first locking position 111 into the second locking position 112.

[0091] The securing device 100 is designed to perform connector position assurance (CPA) to secure the locking of a connector housing 400 to a mating connector housing 401.

[0092] In addition to the locking element 110, indicator element 120 and contrasting element 212 that are already described above, the securing device 100 also includes a clamping element 300, for example a clamping clip, for clamping the connector housing 400 into the mating connector housing 401.

[0093] The clamping element 300 can be moved from an open clamping-element position (see FIG. 3A), in which the connector housing 400 can be inserted into the mating connector housing 401, into a closed clamping-element position (see FIG. 3B), in which the connector housing 400 is fastened to the mating connector housing 401 with electrical contact.

[0094] The locking element 110 is placed on the clamping element 300, for example on a panel or a center piece of the clamping element 300 or clamping clip, as illustrated in FIGS. 3A to 3D, and is designed to lock or to unlock the clamping element 300.

[0095] The identifying feature 200 of the indicator element 120 indicates the locking of the clamping element 300 by the locking element 110. The identifying feature 200 of the indicator element 120 is illustrated by way of example in FIGS. 3A to 3D using the 2D code. Locking is indicated in FIGS. 3B and 3D, whereas no locking is indicated in FIGS. 3A and 3C.

[0096] In the closed clamping-element position, the locking element 110 can be moved from the first locking position 111 (see FIGS. 3A and 3C) into the second locking position 112 (see FIGS. 3B and 3D). The locking element 110 is designed, in the second locking position 112, to lock the clamping element 300 in the closed clamping-element position and, in the first locking position 111, to unlock the clamping element 300 for a movement into the open clamping-element position.

[0097] The indicator element 120 having the identifying feature 200 is placed on the clamping element 300, as can be seen in FIGS. 3A to 3D. The contrasting element 212 is also placed on the clamping element 300, for example on a panel or center piece of the clamping element 300 or clamping clip, as can be seen in FIGS. 3A to 3D.

[0098] When the locking element 110 is being moved from the first locking position 111 (FIGS. 3A and 3C) into the second locking position 112 (FIGS. 3B and 3D), the contrasting surface 213 is made to slide underneath the identifying feature 200, or the identifying feature 200 is made to slide above the contrasting surface 213, as illustrated in FIGS. 3B and 3D, with the result that the identifying feature 200 is readable or discernible in the second locking position 112 (FIGS. 3B and 3D).

[0099] FIGS. 3A to 3D thus also show a plug connection having a connector housing 400 and a mating connector housing 401, which are connected to one another and secured by the securing device 100 as described above.

[0100] Unless otherwise expressly indicated herein, all numerical values indicating mechanical/thermal properties, compositional percentages, dimensions and/or tolerances, or other characteristics are to be understood as modified by the word about or approximately in describing the scope of the present disclosure. This modification is desired for various reasons including industrial practice, material, manufacturing, and assembly tolerances, and testing capability.

[0101] As used herein, the phrase at least one of A, B, and C should be construed to mean a logical (A OR B OR C), using a non-exclusive logical OR, and should not be construed to mean at least one of A, at least one of B, and at least one of C.

[0102] In this application, the term controller and/or module may refer to, be part of, or include: an Application Specific Integrated Circuit (ASIC); a digital, analog, or mixed analog/digital discrete circuit; a digital, analog, or mixed analog/digital integrated circuit; a combinational logic circuit; a field programmable gate array (FPGA); a processor circuit (shared, dedicated, or group) that executes code; a memory circuit (shared, dedicated, or group) that stores code executed by the processor circuit; other suitable hardware components (e.g., op amp circuit integrator as part of the heat flux data module) that provide the described functionality; or a combination of some or all of the above, such as in a system-on-chip.

[0103] The term memory is a subset of the term computer-readable medium. The term computer-readable medium, as used herein, does not encompass transitory electrical or electromagnetic signals propagating through a medium (such as on a carrier wave); the term computer-readable medium may therefore be considered tangible and non-transitory. Non-limiting examples of a non-transitory, tangible computer-readable medium are nonvolatile memory circuits (such as a flash memory circuit, an erasable programmable read-only memory circuit, or a mask read-only circuit), volatile memory circuits (such as a static random access memory circuit or a dynamic random access memory circuit), magnetic storage media (such as an analog or digital magnetic tape or a hard disk drive), and optical storage media (such as a CD, a DVD, or a Blu-ray Disc).

[0104] The apparatuses and methods described in this application may be partially or fully implemented by a special purpose computer created by configuring a general-purpose computer to execute one or more particular functions embodied in computer programs. The functional blocks, flowchart components, and other elements described above serve as software specifications, which can be translated into the computer programs by the routine work of a skilled technician or programmer.

[0105] The description of the disclosure is merely exemplary in nature and, thus, variations that do not depart from the substance of the disclosure are intended to be within the scope of the disclosure. Such variations are not to be regarded as a departure from the spirit and scope of the disclosure.
