[0001] Cross-reference to related applications

[0002] This application claims priority to U.S. Application No. 63 / 751,535, filed January 30, 2025, and U.S. Application No. 63 / 931,776, filed December 5, 2025, the subject of which is incorporated herein by reference in its entirety. Technical Field

[0003] This article generally deals with electrical connectors having connector position guarantee (CPA) devices. Background Technology

[0004] Electrical connector assemblies used in automotive, industrial, and consumer electronics systems increasingly comprise multiple electrical connectors housed within a common housing. This multi-connector arrangement reduces package size and simplifies wiring harness routing by incorporating several individual connectors into a single modular interface. Each individual connector within the housing typically includes its own terminal set, latching features, and mating interface for engagement with a corresponding mating connector component.

[0005] To ensure proper positioning and full engagement of each connector during assembly, many known multi-connector assemblies employ connector position assurance (CPA) devices. Traditional CPA devices are typically associated with a single connector interface and are configured to move between different locations to confirm that the corresponding internal connector is fully inserted into the housing. In multi-connector assemblies, this typically results in the use of a separate CPA device for each connector contained within a common housing.

[0006] While effective for single-connector applications, using multiple independent CPA devices in a shared housing presents several drawbacks. Each CPA must be installed, manipulated, and verified individually during assembly, increasing the total number of manufacturing steps and handling operations. The presence of multiple CPA devices also increases the complexity of the assembly workflow, increases the number of parts, and may introduce opportunities for assembly errors if one or more CPA devices are not properly actuated. Furthermore, additional CPA components contribute to increased material costs and require additional space within or on the housing, which may limit design flexibility.

[0007] Some electrical connector assemblies utilize a data matrix exposure as a form of redundancy after the connector is fully mated and the CPA device is engaged, to ensure complete connector mating. However, some CPA device designs do not provide an easy or convenient exposure location for the data matrix. For example, the sliding direction may not leave enough space for the data matrix exposure, perhaps due to space constraints.

[0008] Therefore, there is a need for improved connector assemblies that combine CPA functionality for multiple connectors while providing redundant assembly guarantees. Summary of the Invention

[0009] In one embodiment, an electrical connector assembly is provided, including an electrical connector for mating with a mating connector. The electrical connector includes a connector housing for retaining contacts. The electrical connector includes a latching element. The electrical connector includes an actuating element. The electrical connector assembly includes a housing body including an outer wall surrounding a cavity for receiving the electrical connector. The housing body includes a latch configured to be operably coupled to the latching element to secure the electrical connector within the cavity. The housing body includes a blocking surface. The electrical connector assembly includes a connector position guarantee (CPA) device coupled to the housing body. The CPA device is movable between a pre-positioned position and an in-positioned position. The CPA device includes a CPA element coupled to the blocking surface in the pre-positioned position. The blocking surface prevents the CPA device from moving from the pre-positioned position to the in-positioned position. The CPA element is configured to abut against an actuating element of the electrical connector. The actuating element is configured to move the CPA element to a gapped position released from the blocking surface when the electrical connector is fully inserted into the cavity. The movement of the CPA device to the in-place position provides mechanical indication that the electrical connector is correctly positioned within the cavity of the housing, and wherein movement of the CPA device is prevented when the electrical connector is not fully inserted into the housing. The electrical connector assembly includes a data matrix comprising a first data matrix portion and a second data matrix portion. The second data matrix portion is coupled to the CPA device and is movable with the CPA device. When the CPA device is in the pre-position position, the first and second data matrix portions are separated from each other to form a split data matrix. When the CPA device is in the in-place position, the first and second data matrix portions are aligned adjacent to each other to form a combined data matrix. The split data matrix is ​​not scannable by a data scanning device, while the combined data matrix is ​​scannable by a data scanning device. Attached Figure Description

[0025] Figure 1An electrical connector assembly 100 according to an exemplary embodiment is shown. The electrical connector assembly 100 can be configured for use in a vehicle. For example, the electrical connector assembly 100 is configured to be mounted at an opening 50 in a panel 60. The panel 60 can be part of the vehicle structure, such as a door panel, body side panel, or any metal plate or composite structure through which electrical interfaces must pass. The electrical connector assembly 100 can be mounted to other structures, such as a chassis, plug, circuit board, or other mounting structure.

[0026] In an exemplary embodiment, the electrical connector assembly 100 is a multi-connector arrangement having multiple electrical connectors, such as a first electrical connector 120 and a second electrical connector 150, assembled together within a common housing 200. However, in an alternative embodiment, the electrical connector assembly 100 may include a single electrical connector. In an exemplary embodiment, the electrical connector assembly 100 includes a connector position assurance (CPA) device 300 to verify that one or more electrical connectors 120, 150 are fully housed within the housing 200.

[0027] The housing 200 may include mounting flanges, latching fingers, or other retaining features adapted to engage the edge of the panel opening 50, such that the housing 200 is held in a fixed position relative to the panel 60. When installed, the housing 200 spans the panel opening 50 and provides an interface accessible from either the inside or outside of the panel 60, depending on application requirements. The electrical connector assembly 100 may also include environmental sealing features formed around or within the housing 200, such as peripheral gaskets, wire seals, or moisture barriers, to prevent water, dust, and debris from entering the panel opening 50.

[0028] In various embodiments, the electrical connector assembly 100 can be positioned at the door-to-body interface of the vehicle, where the circuitry must pass between the movable door and the fixed body structure. In such an application, the housing 200 is mounted to the door panel 60 to position the first and second electrical connectors 120, 150 at the door panel 60, while the mating connector is positioned on the body side. This arrangement allows for a robust and durable electrical interface that can withstand repeated door opening and closing cycles, environmental exposure, and mechanical stress. The CPA device 300 ensures that the first electrical connector 120 and the second electrical connector 150 remain fully in place within the door-side housing and provides reliable electrical continuity during vehicle operation.

[0029] Figure 2 This is a perspective view of an electrical connector assembly 100 according to an exemplary embodiment. Figure 2 A first electrical connector 120 and a second electrical connector 150 are shown, which are fully inserted into and secured within the housing 200. Figure 2 The CPA device 300 is shown in the in-place position.

[0030] In an exemplary embodiment, the electrical connector assembly 100 includes a scannable data matrix 400 configured to be scanned by a data scanning device. For example, the data matrix 400 may be machine-readable and readable by a sensor of the data scanning device. The data matrix 400 may be one of a one-dimensional barcode, a two-dimensional barcode, or a three-dimensional barcode. The data matrix 400 may be a Quick Response (QR) code. The data matrix 400 may be read by a reader or other type of scanning device. The data matrix 400 provides the installer with a redundant positioning guarantee, thereby providing confirmation that the CPA device 300 is correctly positioned and therefore the electrical connector assembly 100 is correctly assembled.

[0031] In an exemplary embodiment, the data matrix 400 includes different portions movable relative to each other, which can be moved from a split position (where the portions are spaced apart from each other) to a combined position (where the portions are combined or joined to form a scannable data matrix 400). For example, the data matrix 400 may include a first data matrix portion 402 located on the housing 200 or other components and a second data matrix portion 404 located on the CPA device 300 and movable with the CPA device 300. When the CPA device 300 is in the preparatory stage position, the first and second data matrix portions 402, 404 are separated from each other to form a non-scannable split data matrix. When the CPA device 300 is in the in-place position, the first data matrix portion 402 and the second data matrix portion 404 are aligned adjacent to each other to form a combined data matrix that can be scanned by a data scanning device.

[0032] In an exemplary embodiment, the data matrix 400 is scannable only when the CPA device 300 is in the in-place position. When the CPA device 300 is in the pre-position position, the data matrix 400 is not scannable. Thus, scanning the data matrix 400 demonstrates to the installer that the first electrical connector 120 is fully engaged, the second electrical connector 150 is fully engaged, and the CPA device 300 is fully connected. All three events can be verified by scanning a single data matrix 400 without requiring multiple CPA devices or multiple data matrices. The scannable data matrix 400 provides the installer with auxiliary indication that connectors 120 and 150 are fully engaged and that the CPA device 300 is fully connected, thereby reducing the risk of incomplete connections during assembly and enhancing overall system reliability.

[0033] In an exemplary embodiment, the CPA device 300 is configured to be operatively coupled to both the first electrical connector 120 and the second electrical connector 150. Movement of the CPA device 300 can be prevented or halted when either of the electrical connectors 120 or 150 is not fully inserted into the housing 200, thereby providing position assurance for both the first electrical connector 120 and the second electrical connector 150 using a single or common CPA component.

[0034] The CPA device 300 can only move from the preparatory stage position to the in-place position when the first electrical connector 120 and the second electrical connector 150 are fully inserted into the housing 200. For example, the CPA device 300 can move inward, for example, in a direction perpendicular to the mating direction of the electrical connector assembly 100. When either the first electrical connector 120 or the second electrical connector 150 is not properly installed, the blocking feature of the CPA device 300 interferes with the corresponding surface of the housing 200, thereby preventing the CPA device 300 from moving to the in-place position. Once the first electrical connector 120 and the second electrical connector 150 reach their intended depth, the latching elements of the housing 200 and the electrical connectors 120, 150 are properly engaged to secure the electrical connectors 120, 150 in the housing 200, and the blocking state of the CPA device 300 is removed, thereby allowing the CPA device 300 to advance from the preparatory stage position to the in-place position. Moving the CPA device to the in-place position provides mechanical verification that the electrical connectors 120 and 150 are correctly positioned within the housing 200.

[0035] In some embodiments, the CPA device 300 also provides an auxiliary locking function when fully actuated, which prevents unintentional retraction or unlocking of the electrical connectors 120, 150, for example, due to vibration, thermal cycling, or mechanical loads encountered during vehicle operation. The CPA device 300 may engage portions of the electrical connectors 120, 150 to limit reverse movement, or may lock one or more latch arms in an engaged state.

[0036] Figure 3This is an exploded perspective view of an electrical connector assembly 100 according to an exemplary embodiment. The electrical connector assembly 100 is a multi-connector arrangement having multiple electrical connectors 120, 150 arranged within a single common housing 200. A CPA device 300 is a multi-connector CPA device configured to be operatively coupled to the multiple electrical connectors 120, 150 to provide correct connector positioning assurance for the multiple electrical connectors 120, 150 using a single common CPA component. In an exemplary embodiment, the electrical connector assembly 100 includes a data matrix 400, wherein data matrix portions 402, 404 are located on different components, such as on the housing 200 and the CPA device 300, respectively. When the electrical connector assembly 100 is assembled, the data matrix portions 402, 404 can be engaged and exposed, and are therefore scannable.

[0037] The first electrical connector 120 and the second electrical connector 150 are separate and independent. The first and second electrical connectors 150 may be similar to or identical to each other, and identical components are identified by the same reference numerals. The first electrical connector 120 can provide signal and / or power connections with its corresponding mating electrical connector. Similarly, the second electrical connector 150 can provide signal and / or power connections with its corresponding mating electrical connector. The electrical connector assembly 100 may include additional electrical connectors (not shown), such as a third electrical connector located between the first and second electrical connectors 120 and 150. A single data matrix 400 can be used to ensure the correct assembly of the plurality of electrical connectors 120 and 150.

[0038] The first electrical connector 120 includes a first connector housing 122 that holds a first contact 124. The first contact 124 may terminate at the end of a wire (not shown).

The rear housing 129 may hold a wire and can be assembled through the front or rear of the housing 200. In an exemplary embodiment, the CPA device 300 is configured to mate with the front housing 128 to ensure that the front housing 128 is properly loaded into the housing 200.

[0039] In an exemplary embodiment, the first electrical connector 120 includes a first latching element 130 extending from a side 132 of the first connector housing 122. The first latching element 130 extends to a distal end 134. The first latching element 130 includes a latching surface 136, for example, at the front surface of the first latching element 130. In an exemplary embodiment, the latching surface 136 is configured to abut against a latching element of the housing 200 to latchably secure the first electrical connector 120 within the housing 200. In an exemplary embodiment, the distal end 134 is configured to abut against a portion of the CPA device 300 to release the CPA device 300 and allow the CPA device 300 to move from a preparatory position to an in-place position when the first electrical connector 120 is fully inserted into the housing 200.

[0040] The second electrical connector 150 includes a second connector housing 152 that holds a second contact 154. The second contact 154 may terminate at the end of a wire (not shown). The second contact 154 may be arranged in a contact channel 156 passing through the second connector housing 152. In various embodiments, the second connector housing 152 is a multi-piece housing having a front housing 158 and a rear housing 159. The front housing 158 holds the second contact 154 and can be assembled through the front of the housing 200. The rear housing 159 may hold a wire and can be assembled through the front or rear of the housing 200. In an exemplary embodiment, the CPA device 300 is configured to mate with the front housing 158 to ensure that the front housing 158 is properly loaded into the housing 200.

[0041] In an exemplary embodiment, the second electrical connector 150 includes a second latching element 160 (shown in dashed lines) extending from a side 162 of the second connector housing 152. The second latching element 160 extends to a distal end 164. The second latching element 160 includes a latching surface 166, for example, at the front surface of the second latching element 160. In an exemplary embodiment, the latching surface 166 is configured to abut against a latching element of the housing 200 to latchably secure the second electrical connector 150 within the housing 200. In an exemplary embodiment, the distal end 164 is configured to abut against a portion of the CPA device 300 to release the CPA device 300 and allow the CPA device 300 to move from a preparatory position to an in-place position when the second electrical connector 150 is fully inserted into the housing 200.

[0042] The housing 200 is configured to receive electrical connectors 120 and 150 and CPA device 300. In an exemplary embodiment, the housing 200 is made of a dielectric material, such as a plastic material. For example, the housing 200 may be a molded part. The housing 200 includes an outer wall 202 surrounding a cavity 204. The housing 200 may include one or more inner walls 206 in the cavity 204. For example, the housing 200 includes a central wall 208 dividing the cavity 204 into a first connector chamber 210 and a second connector chamber 212. The first connector chamber 210 is configured to receive a first electrical connector 120, and the second connector chamber 212 is configured to receive a second electrical connector 150. In an alternative embodiment, the cavity 204 may be divided into other chambers to receive other electrical connectors.

[0043] The housing 200 extends between a front portion 220 and a rear portion 222. The housing 200 includes a top 224 and a bottom 226. The housing 200 includes a first side 230 and a second side 232. In various embodiments, the housing 200 is generally rectangular. For example, the top 224 and bottom 226 may be generally planar and extend parallel to each other. The first side 230 and second side 232 may be generally planar and extend parallel to each other. In the illustrated embodiment, a central wall 208 is generally centered between the first side 230 and the second side 232, such that the first connector chamber 210 and the second connector chamber 212 have similar dimensions. However, in alternative embodiments, the central wall 208 may be located closer to either the first side 230 or the second side 232 to form chambers of different sizes.

[0044] In an exemplary embodiment, the housing 200 includes a CPA cavity 234 for receiving a CPA device 300. The CPA cavity 234 may be located at a top 224 and / or a first side 230 and / or a second side 232. The CPA cavity 234 extends into the housing 200 and allows the CPA device 300 to be recessed within the housing 200 to reduce the overall profile of the electrical connector assembly 100. The CPA cavity 234 provides access through the housing 200 to a cavity 204. This opening allows a portion of the CPA device 300 to extend into the cavity 204.

[0045] In an exemplary embodiment, the housing 200 includes an opening 236 configured to receive a portion of the CPA device 300.

The central wall 208 may include an opening 238 therethrough, which receives a portion of the CPA device 300. For example, when the first electrical connector 120 and the second electrical connector 150 are loaded into the first connector chamber 210 and the second connector chamber 212, the CPA device 300 may be received in openings 236, 238 to mate with the first electrical connector 120 and the second electrical connector 150.

[0046] The housing 200 includes a first latch 240 at a first side 230.

In an exemplary embodiment, housing 200 includes raised walls 282 extending along the first data matrix portion 402 on one or more of its sides (e.g., along three of its sides). Raised walls 282 may form cavities 284 that define the location of the first data matrix portion 402. Raised walls 282 protrude from the first data matrix portion 402 to protect the first data matrix portion 402. In an exemplary embodiment, housing 200 may include a raised platform 286 at data matrix region 280.

In an exemplary embodiment, the central blocking finger 316 is received in an opening 236 and an outer wall 202 to extend into a cavity 204. In an exemplary embodiment, the central blocking finger 316 is configured to be received in an opening 238 in a central wall 208 such that the central blocking finger 316 is located in the first connection chamber 210 and the second connection chamber 212 to abut with the first and second electrical connectors 120, 150. In an exemplary embodiment, the central blocking finger 316 includes a protrusion 318, such as a rib along opposite sides of the central blocking finger 316. The protrusion 318 is configured to engage the housing 200, such as the top wall, to hold the CPA device 300 in various positions. For example, the protrusion 318 may engage the outer wall 202 to hold the CPA device 300 in a preparatory stage position. The protrusion 318 may hold the body 310 in an elevated position above the top wall of the housing 200.

[0053] In an exemplary embodiment, the body 310 is located at the top of the CPA device 300. A first CPA element 320 and a second CPA element 350 extend downward from the body 310 at their opposite sides 312, 314. The body 310 is configured to be received in a CPA cavity 234, for example, along the top 224 of the housing 200.

In an exemplary embodiment, the CPA device 300 includes raised walls 382 extending along one or more sides (e.g., along three of its sides) of the second data matrix portion 404. The raised walls 382 may form cavities 384 that define the location of the second data matrix portion 404. The raised walls 382 protrude from the second data matrix portion 404 to protect the second data matrix portion 404. In an exemplary embodiment, the CPA device 300 includes a data matrix window 386 adjacent to the cavity 384. Data matrix window 386 is configured to be aligned with and to receive the first data matrix portion 402. For example, data matrix window 386 may receive platform 286 and the first data matrix portion 402 to align the first data matrix portion 402 with a second data matrix portion 404. For example, platform 286 may position the first data matrix portion 402 coplanar with the second data matrix portion 404. The second data matrix portion 404 is located near data matrix window 386 such that when the first data matrix portion 402 is received in data matrix window 386, the first and second data matrix portions 402 and 404 can be combined or joined to form a scannable data matrix 400.

[0055] The first CPA element 320 includes a base 322 and a first engagement feature 330 extending from the base 322. For example, the first engagement feature 330 extends downward from the base 322. In the illustrated embodiment, the first engagement feature 330 is located at the front of the base 322. In alternative embodiments, other locations are also possible. The first engagement feature 330 defines a blocking feature of the CPA device 300, which is configured to interfere with a corresponding surface of the housing 200 (e.g., the first latch 240) to prevent the CPA device 300 from moving into an in-place position. For example, the first engagement feature 330 is movable between an engaged position and a gapped position. In the engaged position, the first engagement feature 330 engages the first latch 240 and holds the CPA device 300 in a ready-stage position. The CPA device 300 cannot move from the ready-stage position until the first engagement feature 330 is actuated to the gapped position. In an exemplary embodiment, the first engagement feature 330 is configured to engage with the first electrical connector 120 when the first electrical connector 120 is in the fully loaded position, so as to move the first engagement feature 330 to a gapped position. For example, the blocking state of the CPA device 300 is removed only when the first electrical connector 120 is in the fully loaded position, thereby allowing the CPA device 300 to advance from the preparatory stage position to the in-place position.

[0056] In various embodiments, the first CPA element 320 includes a first guide finger 324 extending from the base 322 for guiding engagement of the first CPA element 320 with the housing 200 (e.g., with the first latch cover 250). For example, the first guide finger 324 may be received in a first guide rail 252 to guide movement of the first CPA element 320, such as vertical movement. In the illustrated embodiment, the first guide finger 324 is located at the outer end of the first CPA element 320. In alternative embodiments, other locations are also possible.

[0057] In various embodiments, the first CPA element 320 includes a first latch blocking finger 326 extending from the base 322. The first latch blocking finger 326 is configured to abut against the first latch 240. For example, the first latch blocking finger 326 may be positioned between the first latch 240 and the first side 230 of the housing 200 to block actuation of the first latch 240 when the first CPA element 320 is in the in-place position. In the illustrated embodiment, the first latch blocking finger 326 is located at the rear of the base 322. In alternative embodiments, other locations are also possible.

[0058] In an exemplary embodiment, the first engagement feature 330 is configured to abut a portion of the housing 200 (e.g., the first latch 240). The first engagement feature 330 includes a deflectable spring beam 332 extending from a base 322 to a distal end 334. The first engagement feature structure 330 includes a blocking tab 336 extending inwardly from the spring beam 332 at the distal end 334. The blocking tab 336 includes an end surface 337 and an inner surface 338. The end surface 337 of the blocking tab 336 is configured to engage and abut a portion of the first latch 240 to prevent movement of the first CPA element 320 relative to the housing 200 and the first latch 240. When the end surface 337 of the blocking tab 336 engages the first latch 240, the CPA device 300 remains in the preparatory stage position and cannot move to the in-position position. In an exemplary embodiment, the inner surface 338 of the blocking tab 336 of the first engagement feature 330 is configured to abut against the first electrical connector 120 when the first electrical connector 120 is inserted into the first connector chamber 210. For example, the first inner surface 338 of the blocking tab 336 may abut against the first latching element 130 (when the first electrical connector 120 is fully inserted into the first connector chamber 210), and the first latching element 130 deflects the spring beam 332 of the first engagement feature 330 to a gapped position. The end surface 337 of the blocking tab 336 is released from the first latch 240 in the gapped position (e.g., the blocking state is removed) to allow the CPA device 300 to move to the in-place position.

[0059] The second CPA element 350 includes a base 352 and a second engagement feature 360 ​​extending from the base 352. For example, the second engagement feature 360 ​​extends downward from the base 352. In the illustrated embodiment, the second engagement feature 360 ​​is located at the front of the base 352. In alternative embodiments, other locations are also possible. The second engagement feature 360 ​​defines a blocking feature of the CPA device 300 configured to interfere with a corresponding surface of the housing 200 (e.g., the second latch 260) to prevent the CPA device 300 from moving to an in-place position. For example, the second engagement feature 360 ​​is movable between an engaged position and a gapped position. In the engaged position, the second engagement feature 360 ​​engages the second latch 260 and holds the CPA device 300 in a ready-stage position. The CPA device 300 cannot move from the ready-stage position until the second engagement feature 360 ​​is actuated to the gapped position. In an exemplary embodiment, the second engagement feature 360 ​​is configured to abut against the second electrical connector 150 when the second electrical connector 150 is in a fully loaded position to move the second engagement feature 360 ​​to the gapped position. For example, the blocking state of the CPA device 300 is removed only when the second electrical connector 150 is in the fully loaded position, thereby allowing the CPA device 300 to advance from the preparatory position to the in-place position.

[0060] In various embodiments, the second CPA element 350 includes a second guide finger 354 extending from the base 352 for guiding engagement of the second CPA element 350 with the housing 200 (e.g., with the second latch cover 270). For example, the second guide finger 354 may be received in a second guide rail 272 to guide movement of the second CPA element 350, such as movement in the vertical direction. In the illustrated embodiment, the second guide finger 354 is located at the outer end of the second CPA element 350. In alternative embodiments, other locations are also possible.

[0061] In various embodiments, the second CPA element 350 includes a second latch blocking finger 356 extending from the base 352. The second latch blocking finger 356 is configured to abut against the second latch 260. For example, the second latch blocking finger 356 may be positioned between the second side 232 of the housing 200 and the second latch 260 to block actuation of the second latch 260 when the second CPA element 350 is in the in-place position. In the illustrated embodiment, the second latch blocking finger 356 is located at the rear of the base 352. In alternative embodiments, other locations are also possible.

[0062] In an exemplary embodiment, the second engagement feature 360 ​​is configured to abut a portion of the housing 200 (e.g., the second latch 260). The second engagement feature 360 ​​includes a deflectable spring beam 362 extending from a base 352 to a distal end 364. The second engagement feature structure 360 ​​includes a blocking tab 366 extending inwardly from the spring beam 362 at the distal end 364. The blocking tab 366 includes an end surface 367 and an inner surface 368. The end surface 367 of the blocking tab 366 is configured to engage and abut a portion of the second latch 260 to prevent movement of the second CPA element 350 relative to the housing 200 and the second latch 260. When the end surface 367 of the blocking tab 366 engages the second latch 260, the CPA device 300 remains in the preparatory stage position and cannot move to the in-position position. In an exemplary embodiment, the inner surface 368 of the blocking tab 366 of the second engagement feature 360 ​​is configured to abut against the second electrical connector 150 when the second electrical connector 150 is inserted into the second connector chamber 212. For example, the second inner surface 368 of the blocking tab 366 may abut against the second latching element 160 (when the second electrical connector 150 is fully inserted into the second connector chamber 212), and the second latching element 160 deflects the spring beam 362 of the second engagement feature 360 ​​to a gapped position. The end face 367 of the blocking tab 366 is released from the second latch 260 in the gapped position (e.g., the blocking state is removed) to allow the CPA device 300 to move to the in-place position.

[0063] Figure 4 This is a perspective view of the electrical connector assembly 100, showing the CPA device 300 in a preparatory stage position. Figure 5 This is a cross-sectional view of the electrical connector assembly 100, showing the CPA device 300 in the preparatory stage position. Figure 6 This is a cross-sectional view of the electrical connector assembly 100, showing the CPA device 300 in a preparatory stage position, wherein the first electrical connector 120 and the second electrical connector 150 are removed to show the CPA device 300 relative to the housing 200. In the preparatory stage position, the first and second data matrix portions 402, 404 are separated from each other, thereby forming a non-scannable split data matrix.

[0064] When assembled, the protrusion 318 along the center blocking finger 316 can engage the outer wall 202 to hold the CPA device 300 in the pre-position position. When assembled, the first CPA element 320 and the second CPA element 350 can engage the housing 200 to position and / or hold the CPA device 300 in the pre-position position relative to the housing 200. For example, the first guide finger 324 and the second guide finger 354 can be received in the first guide rail 252 and the second guide rail 272, respectively. The guide rails 252 and 272 guide the movement of the guide fingers 324 and 354, for example, in the vertical direction, to control the CPA device 300 from the pre-position position to the in-position position (e.g., ...). Figure 2 The movement of (as shown). In an exemplary embodiment, the first engagement feature 330 and the second engagement feature 360 ​​engage the housing 200 (e.g., at the first latch 240 and the second latch 260) to hold the CPA device 300 in the preparatory stage position. For example, the end surfaces 337 and 367 of the blocking tabs 346 and 366 engage the first latch 240 and the second latch 260 to hold the CPA device 300 in the preparatory stage position. When the engagement features 330 and 360 are in the engaged position ( Figure 6 And when engaging the housing 200 (for example, until engaging features 330, 360 move to the gap position ( Figure 5 The CPA device 300 cannot be moved to the in-place position.

[0065] In an exemplary embodiment, the first latch 240 and the second latch 260 include latch windows 246 and 266 in latch arms 242 and 262. Latch windows 246 and 266 are openings having arm portions 248 and 268 of the latch arms 242 and 262 extending above and below the openings. Latch fingers 244 and 264 are located in front of latch windows 246 and 266. Latch windows 246 and 266 are configured to receive a first latch element 130 and a second latch element 160 when the first electrical connector 120 and the second electrical connector 150 are fully loaded into the housing 200. When the first latch element 130 and the second latch element 160 are received in latch windows 246 and 266, latch elements 130 and 160 are latchably coupled to the first latch 240 and the second latch 260. For example, latch fingers 244 and 264 engage latch elements 130 and 160 and prevent the first connector 120 and the second connector 150 from being removed from the housing 200.

[0066] When the CPA device 300 is in the preparatory stage position, the blocking tabs 336, 366 located at the distal ends 334, 364 of the spring beams 332, 362 are received in the latch windows 246, 266, and when in the engaged position ( Figure 6 The first electrical connector 120 and the second electrical connector 150 are fully loaded into the first connector chamber 210 and the second connector chamber 212, respectively. The first latching element 130 and the second latching element 160 engage the blocking tabs 336 and 366 and press the blocking tabs 336 and 366 outwards out of the latching windows 246 and 266. The first latching element 130 and the second latching element 160 move the first engagement feature 330 and the second engagement feature 360 ​​to the gap position. The first latching element 130 and the second latching element 160 move the end surfaces 337 and 367 of the blocking tabs 346 and 366 away from the arm portions 248 and 268, allowing the CPA device 300 to move downwards from the preparatory stage position to the in-place position. The CPA device 300 can only move from the preparatory stage position to the in-place position when both engagement features 330 and 360 have moved to the gap position. For example, if one of the engagement features 330, 360 is in the engaged position (e.g., when one of the electrical connectors 120, 150 is not fully loaded into the housing 200 and therefore the latching elements 130, 160 are not received in the latching windows 246, 266), the CPA device 300 is still prevented from moving from the preparatory position to the in-position position. The CPA device 300 can only move to the in-position position when both electrical connectors 120, 150 are fully loaded into the housing 200.

[0067] Figure 7This is a top perspective view of the electrical connector assembly 100, showing the CPA device 300 in the preparatory stage position and the split data matrix 410. Figure 8 This is a top view of a portion of the electrical connector assembly 100, showing the split data matrix 410. Figure 9 This is a top perspective view of the electrical connector assembly 100, showing the CPA device 300 in the in-place position and the joint data matrix 420. Figure 10 This is a top view of a portion of the electrical connector assembly 100, showing the joint data matrix 420.

[0068] The electrical connector assembly 100 includes a data matrix 400, wherein data matrix portions 402 and 404 are located on different components, such as on the housing 200 and the CPA device 300, respectively. In an exemplary embodiment, the second data matrix portion 404 can be moved from a split position to a joined position relative to the first data matrix portion 402, together with the CPA device 300. When the CPA device 300 is in the preparatory stage position, the first and second data matrix portions 402 and 404 are separated from each other to form a non-scannable split data matrix 410. The split data matrix 410 may be non-scannable due to parallax effects, such as due to different heights and / or based on positional changes due to viewing angles. The split data matrix 410 may also be non-scannable due to observable seams between the first and second data matrix portions 402 and 404. When the CPA device 300 is in the in-place position, the first and second data matrix portions 402 and 404 are aligned adjacent to each other to form a joined data matrix 420 that can be scanned by a data scanning device. CPA device 300 may include features such as positioning ribs, magnetic elements, or other types of mechanical features for properly positioning the first and second data matrix portions 402, 404 adjacent to each other to minimize seams and increase scan readability. The pattern of the data matrix may have a robust finder pattern or a relatively large size to accommodate scanning of the two halves of the joint data matrix 420, for example, to accommodate any occlusion in the data matrix, such as slight seams or slight misalignments from matrix portions 402, 404. The reader or scanner may use ECC200 error correction or other advanced error correction methods, such as the Reed-Solomon algorithm, to allow data recovery from the occluded joint data matrix 420.

[0069] In an exemplary embodiment, a first data matrix portion 402 is disposed at a data matrix region 280 of the housing 200, for example, at the top 224 of the housing 200. For example, the first data matrix portion 402 may be coupled to a raised platform 286 at the data matrix region 280 in a cavity 284. A raised wall 282 extends along the side of the first data matrix portion 402 to protect it.

[0070] In an exemplary embodiment, a second data matrix portion 404 is disposed at the data matrix region 380 of the CPA device 300, for example, along the body 310. The second data matrix portion 404 is located near the data matrix window 386. For example, the second data matrix portion 404 extends along the edge of the data matrix window 386. A raised wall 382 surrounds the second data matrix portion 404, for example, along its three sides, to protect the second data matrix portion 404.

[0071] The data matrix window 386 is aligned with the raised platform 286. For example, the data matrix window 386 may be directly vertically positioned above the raised platform 286. The CPA device 300 moves from a preparatory position to an in-place position in a vertical direction, such as perpendicular to the mating direction of the electrical connectors 120, 150. The raised platform 286 is received within the data matrix window 386 to align the first data matrix portion 402 with the second data matrix portion 404. In various embodiments, the raised platform 286 may be the same size as the data matrix window 386 such that the edge defining the data matrix window 386 centers or positions the raised platform 286 within the data matrix window 386 to align the first and second data matrix portions 402, 404 with each other. In an exemplary embodiment, the platform 286 positions the first data matrix portion 402 coplanar with the second data matrix portion 404. The raised platform 286 can be received in the data matrix window 386 by interference or close fitting to ensure that the first and second data matrix portions 402, 404 are aligned and combined to form a joint data matrix 420.

[0072] In an exemplary embodiment, the first data matrix portion 402 includes a first inner edge 406, and the second data matrix portion 404 includes a second inner edge 408. When the CPA device 300 is in the preparation stage position ( Figure 8 When the first inner edge 406 and the second inner edge 408 are in the in-place position, they are separated from each other by a gap 430 having a separation distance. Figure 10When the first inner edge 406 and the second inner edge 408 are spaced apart, the data matrix 400 is adjacent to each other and joined. For example, when the CPA device 300 is in the in-place position, the gap 430 is eliminated in the joined position. When the first and second inner edges 406, 408 are spaced apart, the data matrix 400 is unscannable. When the first inner edge 406 and the second inner edge 408 are joined, the data matrix 400 is readable and scannable.

Figure 12 This is another perspective view of the electrical connector system 10, showing the mating connector assembly 20 that partially mates with the electrical connector assembly 100. Figure 13 This is a perspective view of the electrical connector system 10, showing the mating connector assembly 20 that fully mates with the electrical connector assembly 100. Figure 14 This is a top view of part of the electrical connector system 10, showing the data matrix 400 in an joined and scannable state.

[0074] In the illustrated embodiment, the electrical connector system 10 includes a mating assist rod 500 to assist mating of the mating connector assembly 20 with the electrical connector assembly 100. In an exemplary embodiment, the mating assist rod 500 is coupled to the housing 22 of the mating connector assembly 20. In an alternative embodiment, the mating assist rod 500 is coupled to the outer housing 200 of the electrical connector assembly 100. The mating assist rod 500 is in an open position relative to the housing 200 (…). Figure 11 and Figure 12 ) and closed position ( Figure 13 Rotate between ).

[0075] Data matrix 400 includes a first data matrix portion 402 and a second data matrix portion 404. In an exemplary embodiment, the first data matrix portion 402 is located on the mating assist rod 500, and the second data matrix portion 404 is located on the CPA device 300. The first data matrix portion 402 is movable with the mating assist rod 500. The second data matrix portion 404 is movable with the CPA device 300. When the CPA device 300 is in the preparatory stage position and / or when the mating assist rod 500 is in the open position, the first data matrix portion 402 and the second data matrix portion 404 are separated from each other to form a non-scannable split data matrix. Only when the CPA device 300 is in the in-place position and the mating assist rod 500 is in the closed position are the first data matrix portion 402 and the second data matrix portion 404 aligned adjacent to each other to form a joint data matrix that can be scanned by a data scanning device. In this way, a single data matrix 400 can be used to ensure the correct assembly of connector assemblies 20, 100.
