[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] Therefore, there is a need for improved connector assemblies that combine CPA functionality for multiple connectors while reducing the number of parts and assembly steps required to ensure proper connector mating. Summary of the Invention

[0008] In one embodiment, an electrical connector assembly is provided, including a first electrical connector for mating with a first mating connector. The first electrical connector includes a first connector housing for retaining a first contact. The first electrical connector includes a first latching element. The electrical connector assembly includes a second electrical connector for mating with a second mating connector. The second electrical connector includes a second connector housing for retaining a second contact. The second electrical connector includes a second latching element. The electrical connector assembly includes a housing including an outer wall surrounding a cavity. The housing includes an inner wall dividing the cavity into a first connector chamber for receiving the first electrical connector and a second connector chamber for receiving the second electrical connector. The housing includes a first latch located on a first side of the housing and a second latch located on a second side of the housing. The first latch is configured to be operatively coupled to the first latching element to secure the first electrical connector in the first connector chamber. The second latch is configured to be operatively coupled to the second latching element to secure the second electrical connector in the second chamber. The electrical connector assembly includes a connector position guarantee (CPA) device coupled to the housing. The CPA device is movable between a pre-position position and an in-position position. The CPA device includes a body, a first CPA element configured to mate with a first latch and a first electrical connector, and a second CPA element configured to mate with a second latch and a second electrical connector. Movement of the CPA device to the in-place position provides mechanical indication that both the first and second electrical connectors are correctly positioned within the housing, and movement of the CPA device is prevented when at least one of the first and second electrical connectors is not fully inserted into the housing.

[0024] Figure 1 An 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, a body side panel, or any metal plate or composite structure through which electrical interfaces must pass.

[0025] 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. In an exemplary embodiment, the electrical connector assembly 100 includes a connector position assurance (CPA) device 300 to verify that the electrical connectors 120, 150 are fully seated within the housing 200.

[0026] In an exemplary embodiment, the CPA device 300 and housing 200 are configured to be assembled through an opening 50 in the panel 60 during assembly. For example, the CPA device 300 and housing 200 have a profile that assembles through the opening 50 and is configured to pass through the opening 50 during assembly. The outer profile of the CPA device 300 and housing 200 may have a shape corresponding to the shape of the opening 50. In the illustrated embodiment, the opening 50 is elliptical, having edges at opposing upper ends 52 and lower ends 54 and opposing side surfaces 56, 58. The upper ends 52 and lower ends 54 may be straight and parallel to each other. The first side 56 and the second side 58 may be curved between the upper ends 52 and lower ends 54. In alternative embodiments, the opening 50 may have other shapes.

[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 2A 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 A CPA device 300 is shown in a mating position with a first electrical connector 120, a second electrical connector 150, and a housing 200. 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.

[0030] 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.

[0031] 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.

[0032] Figure 3 This 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 a plurality of electrical connectors 120, 150 arranged within a single common housing 200. The CPA device 300 is a multi-connector CPA device configured to be operatively coupled to the plurality of electrical connectors 120, 150 to provide correct connector positioning assurance for the plurality of electrical connectors 120, 150 using a single common CPA component.

[0033] 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.

[0034] 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 first contact 124 may be arranged in a contact channel 126 passing through the first connector housing 122. In various embodiments, the first connector housing 122 is a multi-piece housing having a front housing 128 and a rear housing 129. The front housing 128 holds the first contact 124 and can be assembled through the front of the housing 200. 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] In an exemplary embodiment, the housing 200 includes an opening 236 configured to receive a portion of the CPA device 300. The opening 236 may be aligned with a central wall 208 to allow a portion of the CPA device 300 to extend along the central wall 208. 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.

[0042] The housing 200 includes a first latch 240 at a first side 230. The first latch 240 is configured to be latchably coupled to a first electrical connector 120, for example, to a first latching element 130. In an exemplary embodiment, the first latch 240 is a deflectable latch configured to be released to release the first electrical connector 120 from the housing 200. In an exemplary embodiment, the first latch 240 includes a latch arm 242 and a latch finger 244 at a distal end of the latch arm 242, the latch finger 244 being configured to engage a latching surface 136 of the first latching element 130.

[0043] In an exemplary embodiment, the housing 200 includes a first latch guard 250 surrounding a portion of the first latch 240. The first latch guard 250 may extend outward from the first side 230. In the illustrated embodiment, the first latch guard 250 has a curvature that can match the opening 50 in the panel 60 (e.g., Figure 1 The curvature (as shown). In an exemplary embodiment, the housing 200 includes a first guide rail 252 configured to receive a portion of the CPA device 300. In the illustrated embodiment, the first guide rail 252 is located within a first latch cover 250. The first guide rail 252 is used to guide movement of the CPA device 300 relative to the housing 200.

[0044] The housing 200 includes a second latch 260 at a second side 232. The second latch 260 is configured to be latchably coupled to a second electrical connector 150, for example, to a second latching element 160. In an exemplary embodiment, the second latch 260 is a deflectable latch configured to be released to release the second electrical connector 150 from the housing 200. In an exemplary embodiment, the second latch 260 includes a latch arm 262 and a latch finger 264 at a distal end of the latch arm 262, the latch finger 264 being configured to engage a latching surface 166 of the second latching element 160.

[0045] In an exemplary embodiment, the housing 200 includes a second latch guard 270 surrounding a portion of the second latch 260. The second latch guard 270 may extend outward from the second side 232. In the illustrated embodiment, the second latch guard 270 has a curvature that can match the opening 50 in the panel 60 (e.g., Figure 1 The curvature (as shown). In an exemplary embodiment, the housing 200 includes a second guide rail 272 configured to receive a portion of the CPA device 300. In the illustrated embodiment, the second guide rail 272 is located within a second latch cover 270. The second guide rail 272 is used to guide movement of the CPA device 300 relative to the housing 200.

[0046] In an exemplary embodiment, the CPA device 300 is an integral, single-piece component configured to attach to a housing 200 and mate with a plurality of electrical connectors 120, 150 received within the housing 200. The CPA device 300 includes a body 310, a first CPA element 320 extending from a first side 312 of the body 310, and a second CPA element 350 extending from a second side 314 of the body 310. The first CPA element 320 is configured to mate with a first latch 240 and the first electrical connector 120. The second CPA element 350 is configured to mate with a second latch 260 and the second electrical connector 150.

[0047] In an exemplary embodiment, the CPA device 300 includes a central blocking finger 316 extending from the inner surface of the body 310. The central blocking finger 316 is configured to be positioned between the first electrical connector 120 and the second electrical connector 150, and the central blocking finger 316 can directly abut with the first electrical connector 120 and the second electrical connector 150 when the first electrical connector 120 and the second electrical connector 150 are inserted into the first connector chamber 210 and the second connector chamber 212. 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.

[0048] 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. The first CPA element 320 and the second CPA element 350 may be received in the CPA cavity 234. In an exemplary embodiment, the first CPA element 320 and the second CPA element 350 are configured to be received in a first latch cover 250 and a second latch cover 270, respectively. The latch covers 250, 270 may cover or protect components of the CPA elements 320, 350.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] Figure 7 This is a side view of the electrical connector assembly 100, showing the CPA device 300 in the preparatory stage position. Figure 8 This is a side view of the electrical connector assembly 100, showing the CPA device 300 in the in-place position. In an exemplary embodiment, rails 252, 272 guide the movement of guide fingers 324, 354, for example, in the vertical direction, to control the movement of the CPA device 300 from the pre-position position to the in-place position. The CPA device 300 is in a raised position in the pre-position position. For example, the body 310 is raised above the top 224 of the housing 200. When the CPA device 300 is in the pre-position position, the electrical connector assembly 100 has a higher profile. Due to the higher profile, the electrical connector assembly 100 may not be able to fit through the opening 50 in the panel 60 (e.g., Figure 1 (As shown), this provides the installer with a mechanical or visual indication that the electrical connector assembly 100 is not properly assembled.

[0062] In an exemplary embodiment, the latch blocking finger 326 is configured such that when the CPA device 300 is in the in-place position ( Figure 8 The latch blocking finger 326 can be moved to align with and be positioned behind the latch arm 242 of the first latch 240. The latch blocking finger 326 can be positioned between the latch arm 242 and the side 230 of the housing 200 to block actuation of the first latch 240, thereby preventing the first latch 240 from being released from the first electrical connector 120.

[0063] Figure 9 This is a cross-sectional view of a portion of the electrical connector assembly 100, showing the CPA device 300 in the in-place position. In the in-place position, the engagement feature 330 is in a gapped position and not abutting the first latch 240. In the in-place position, the latch blocking finger 326 moves to align with and is positioned behind the latch arm 242 of the first latch 240. The latch blocking finger 326 may be located between the latch arm 242 and the side 230 of the housing 200 to block actuation of the first latch 240, thereby preventing the first latch 240 from being released from the first electrical connector 120.

[0064] Figure 10This is a front view of the electrical connector assembly 100 relative to the panel 60 and opening 50, showing the CPA device 300 in the pre-engaged position. In the pre-engaged position, the CPA device 300 is raised relative to the housing 200. The CPA device 300 increases the outline or outer perimeter of the electrical connector assembly 100. For example, with the CPA device 300 and in the pre-engaged position, the outer perimeter of the electrical connector assembly 100 may be larger than the opening 50 to prevent loading the electrical connector assembly 100 through the opening 50. The CPA device 300 provides the installer with visual confirmation of assembly completion. For example, when the CPA device 300 is in the raised position, this provides a clear visual indication that the CPA device 300 is not fully engaged, reducing the risk of incomplete connection during assembly and enhancing the reliability of the overall system. When the CPA device 300 is in the pre-engaged position, the installer cannot install the electrical connector assembly 100 into the opening 50. The CPA device 300 is designed so that the assembly will not be assembled through the opening 50 in the pre-engaged or partially engaged position. The electrical connector assembly 100 will only pass through the opening 50 when the CPA device 300 is fully in place. This design allows the installer to verify that the first electrical connector 120 is fully engaged, the second electrical connector 150 is fully engaged, and the CPA device 300 is fully mated. All three events can be certified using a single CPA device 300 without requiring multiple CPA devices or other assembly steps.

Figure 12 This is a side view of the electrical connector assembly 100, showing the CPA device 300 in the in-place position. In an exemplary embodiment, the electrical connector assembly 100 includes a scannable data matrix 400 on the housing 200. When the CPA device 300 is in the pre-position position ( Figure 11 When the scannable data matrix 400 is obstructed and cannot be scanned, the CPA device 300 is in the in-place position. Figure 12 When the scannable data matrix 400 is displayed and scannable, it provides the installer with auxiliary indications that the connectors 120 and 150 are fully mated and the CPA device 300 is fully engaged, reducing the risk of incomplete connections during assembly and enhancing the reliability of the entire system.

[0066] Figure 13 This is a perspective view of the electrical connector assembly 100 positioned relative to the opening 50 in the panel 60 according to an exemplary embodiment. Figure 14This is a side view of the electrical connector assembly 100, according to an exemplary embodiment, partially loaded through an opening 50 in the panel 60. In the illustrated embodiment, the electrical connector assembly 100 includes a mechanical auxiliary rod 500 to assist in the mating of electrical connectors 120, 150. A CPA device 300 is disposed on the mechanical auxiliary rod 500. The mechanical auxiliary rod 500 is available in an open position relative to the housing 200 ( Figure 13 ) and closing position ( Figure 14 The electrical connector assembly 100 is sized to fit through the opening 50 in the panel 60 only when the mechanical assist lever 500 is in the closed position and the CPA device 300 is in the actuated position. If the mechanical assist lever 500 is in the open position and / or the CPA device 300 is in the unactuated or preparatory position, the electrical connector assembly 100 is too large to fit through the opening 50. This design ensures that the electrical connector assembly 100 is fully and correctly assembled before it can be coupled to the panel 60.
