This application claims priority to and the benefit of DE 10 2023 114 791.9 filed on Jun. 6, 2023. The disclosure of the above-referenced application is incorporated herein by reference.
The present disclosure relates to a securing device having an identifying feature to secure the locking of a locking element.
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
CPA (connector position assurance) systems are intended to inhibit a connector housing latched to a mating connector housing from being inadvertently detached from the mating connector housing, as can happen for example due to vibrations, temperature-related expansion or shrinkage, pulling on a cable accommodated in the connector housing, or other mechanical effects. For this, the CPA system is responsible for locking the connector to its mating connector, as the last element to be operated. In order to provide secure locking here, it is necessary for the final state of the locking to be detected by virtue of a scannable element and for this element to be readable when the CPA system is finally closed.
This section provides a general summary of the disclosure and is not a comprehensive disclosure of its full scope or all of its features.
The present disclosure relates to a securing device having an identifying feature (primary identifying feature) as part of a second identifying feature (secondary identifying feature). The securing device serves to secure the locking of a locking element or for connector position assurance (CPA) and can be used to secure the locking of a connector housing to a mating connector housing. In particular, the present disclosure relates to a CPA system having a detectable sub-element.
The present disclosure provides a suitable device which makes it possible to reliably discern if locking is present or not, in particular for connectors for which CPA locking is desired.
The connector may have a high degree of automation in terms of production and fabrication makes the use of a scannable element desired as an assurance function. The present disclosure presented here relates to a securing device including an indicator element having an identifying feature and a contrasting element, wherein a contrast of the identifying feature is modified by the contrasting element and the indicator element can therefore be used as a scannable element, in order to provide reliable assurance of the connector production process and make it possible to scan the plug system in the assembled state. The solution presented here can be applied to various plug systems and can be easily adapted from one plug system to another plug system.
The main feature of the solution according to the present disclosure is an element to be detected, which is on the CPA system and can be detected after the CPA system is actuated. Furthermore, this element cannot be detected in the open position of the CPA system, in that either it is a sub-element of another element to be detected or the contours are manipulated.
According to a first aspect, the present disclosure provides a securing device for securing the locking of a locking element, wherein the securing device includes the following: a locking element, which can be moved from a first locking position into a second locking position, wherein the locking element produces locking in the second locking position; an indicator element having an identifying feature for indicating an item of information; wherein, in the first locking position of the locking element, the identifying feature is part of a second identifying feature, and therefore the identifying feature cannot be discerned separately; and wherein, in the second locking position of the locking element, the identifying feature is not part of the second identifying feature, and therefore the identifying feature can be discerned separately.
Here, the identifying feature is also referred to as primary identifying feature and the second identifying feature as secondary identifying feature.
The item of information may be any desired item of information. In particular, the item of information is an item of information regarding locking or non-locking by the locking element. The item of information may additionally also contain other things, for example user information, serial number of the securing device or of individual components of the device, instructions for the user, etc.
Such a securing device affords the technical advantage that it is possible to securely and reliably discern locking. The indicator element having the identifying feature can be detected via a scannable element, with the result that it is possible to reliably automatically discern the item of information and thus a position of the locking element. This also makes it possible to automatically detect the state of connectors for which CPA locking is desired. The securing device thus meets the standards for CPA locking.
The identifying feature may, for example, be a code, for example a one- or multi-dimensional code, or a pictogram or a symbol.
According to one example of the securing device, in both of the locking positions of the locking element, the identifying feature is not concealed and always remains visible.
This affords the technical advantage that covering the indicator element having the identifying feature to achieve the desired effect of non-discernibility may be omitted. The modification of the identifying feature, in that the identifying feature is part of a second identifying feature, is already sufficient to make the identifying feature unrecognizable, so that the identifying feature can no longer be detected or discerned separately by a scannable element. The scannable element can then only detect the second identifying feature, but not the identifying feature as a separate unit.
According to one example of the securing device, when the locking element is being moved from the first locking position into the second locking position, the identifying feature is made to slide out of the second identifying feature, and therefore the identifying feature can be discerned separately in the second locking position.
This affords the technical advantage that an ability to discern the identifying feature can be easily controlled by actuation of the locking element. When the locking element is actuated by being moved into the second locking position, the identifying feature is made to move out of the second identifying feature and can be discerned as a separate feature, which is no longer part of the second identifying feature, and therefore it is possible to reliably discern the presence of a locking effect.
According to one example of the securing device, in the first locking position, the second identifying feature completely or at least partially surrounds the identifying feature.
This affords the technical advantage that the identifying feature can no longer be discerned as a separate feature as a result and it can thus be reliably inferred from this that the locking element is in the first locking position, and therefore no locking is present. A widening of the edge of the identifying feature is also already sufficient for it to no longer be discernible separately.
According to one example of the securing device, the identifying feature has contours which delimit the identifying feature with respect to a surrounding area; wherein, in the first locking position, the contours of the identifying feature are made unrecognizable or obfuscated by the second identifying feature; and wherein, in the second locking position, the contours of the identifying feature are not made unrecognizable or obfuscated by the second identifying feature.
This affords the technical advantage that the obfuscation of the contours of the identifying feature has the effect that it can no longer be discerned separately, with the result that it is possible to make a distinction between the “locked” and “unlocked” states.
According to one example of the securing device, the identifying feature includes a code, for example a one- or multi-dimensional code; and the second identifying feature includes a second code, for example a second one- or multi-dimensional code; wherein the code is not discernible when it is part of the second code.
This affords the technical advantage that it is easily possible to be able to make a distinction on the basis of codes. Codes suitable for this, for example 1D, 2D or 3D codes, have a strong contrast, and can therefore be read easily by a reading element.
According to one example of the securing device, the identifying feature includes a one-dimensional or multi-dimensional code, for example a data matrix code, DMC, or a QR code or a barcode.
The data matrix code is one of the best known 2D codes and can be used for permanent and robust direct labelling. The DMC is variable in size and thus permits a multiplicity of symbol elements. QR codes and barcodes are also suitable as identifying feature and/or second identifying feature.
According to one example of the securing device, the identifying feature is discernible when it is not part of the second identifying feature.
This affords the technical advantage that the state of the locking element can be discerned securely and reliably, for example can be determined via a reader or a scanner. This makes it possible to efficiently assure automated mounting of plug systems.
According to one example of the securing device, the securing device is designed to perform connector position assurance (CPA) to secure the locking of a connector housing to a mating connector housing.
This affords the technical advantage that the state of the CPA system can be reliably detected by virtue of a scannable element, which is readable only when the CPA system is finally closed.
According to one example of the securing device, the securing device also includes: a clamping element for clamping the connector housing into the mating connector housing, wherein the clamping element can be moved from an open clamping-element position, in which the connector housing can be inserted into the mating connector housing, into a closed clamping-element position, in which the connector housing is fastened to the mating connector housing with electrical contact; wherein the locking element is placed on the clamping element and designed to lock or to unlock the clamping element. As already described above, the indicator element indicates an item of information, for example an item of information about the locking of the clamping element by the locking element.
This affords the technical advantage that the indicator element reliably indicates an item of information, for example an item of information regarding the locking of the clamping element, for example a clip, so that the state of the clamping element can be reliably discerned, for example by way of a scannable element.
According to one example of the securing device, in the closed clamping-element position, the locking element can be moved from the first locking position into the second locking position and is designed, in the second locking position, to lock the clamping element in the closed clamping-element position and, in the first locking position, to unlock the clamping element for a movement into the open clamping-element position.
This affords the technical advantage that a secure connection of the connector housing to the mating connector housing via the clamping element is provided. The securing device thus meets the standards for CPA locking.
According to one example of the securing device, the identifying feature and the second identifying feature are placed on the clamping element; and a movement of the locking element from the first locking position into the second locking position makes the identifying feature slide out of the second identifying feature, and therefore the identifying feature can be discerned separately in the second locking position.
This affords the technical advantage that the indicator element can reliably and robustly indicate an item of information, for example an item of information regarding locking. In the first locking position, the identifying feature is enclosed by a second identifying feature, and therefore the identifying feature cannot be discerned separately and no information (for example an item of information about the locking) can be discerned. In the second locking position, the identifying feature is no longer enclosed by the second identifying feature, and therefore the identifying feature can be discerned separately, for example via a scannable element or visually by a user.
According to a second aspect, the present disclosure provides a plug connection having a connector housing and a mating connector housing, which are connected to one another and secured by a securing device according to the first aspect.
According to a third aspect, the present disclosure provides a securing system including a securing device according to the first aspect and a reader, wherein the reader is designed to detect the identifying feature of the indicator element when the locking element is in the second locking position, in order to discern an item of information, for example an item of information about the locking.
According to one example of the securing 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 correct locking only in this position.

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
An example with a CPA system in which the identifying feature 200 is a DMC including black and white pixels, as illustrated in
The element to be detected, i.e. the identifying feature 200, illustrated as a DMC in
After the CPA system is actuated, in the second locking position 112, or position 2, only the identifying feature 200 or DMC on the CPA system is scannable, since the DMC as sub-element is also scannable on its own.
The securing device 100, as described above in relation to
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 this position 112.
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 it detects one and take corresponding steps to control the production or fabrication process.
Here, the identifying feature 200 or circle, which corresponds to the identifying feature 200, is on the CPA system and, in the first locking position 111 (see
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.
In addition to the locking element 110 and indicator element 120 having an identifying feature 200 and a second identifying feature 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.
The clamping element 300 can be moved from an open clamping-element position, in which the connector housing 400 can be inserted into the mating connector housing 401, into a closed clamping-element position, in which the connector housing 400 is fastened to the mating connector housing 401 with electrical contact.
