MCC Docket No. 11694-117WO1CONNECTION POSITION ASSURANCE DEVICE AND SYSTEMCROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority to and the benefit of U.S. Provisional Patent Application No. 63 / 754,054, filed February 5, 2025, the entire contents of which are incorporated herein by reference.BACKGROUND
[0002] Electrical connectors (e.g., in vehicles and other applications) often feature housings that protect the internal terminals and facilitate secure connections. In many cases, these housings are designed to couple with other housings (e.g., a male and female side of the connection), allowing for modular connections between different parts of a system. This capability ensures proper alignment, environmental sealing, and mechanical stability.
[0003] However, existing housings for electrical connectors may not include adequate structural elements to ensure a proper mechanical and / or electrical coupling between corresponding connector assemblies. Additionally, existing systems that attempt to ensure proper mechanical and / or electrical coupling are often susceptible to breakage, and they may not properly communicate the connection position information to a user.
[0004] Therefore, a need exists for more reliable and robust electrical connector assemblies.SUMMARY

[0083] Following below are more detailed descriptions of concepts related to, and implementations of, methods, apparatuses, systems, and devices for a wrap-around connection position assurance (CPA) device. The figures illustrate exemplary implementations in detail and the present disclosure is not limited to the details or methodology set forth in the description or illustrated in the figures. The terminology used herein is for the purpose of description only and should not be regarded as limiting.
[0084] Referring to the figures generally, the various implementations disclosed herein relate to systems, apparatuses, devices, and methods for a connector assembly. For example, a connector assembly may include an insulative housing and a conductive terminal. A connector assembly may further include a connection position assurance (CPA) device. The CPA device is couplable to the housing of the connector assembly.
[0085] The connector assembly may be a first connector assembly that is removably couplable to a second connector assembly that includes a second insulative housing and a second conductiveMCC Docket No. 11694-117WO1terminal. The CPA device may be further couplable to the second connector assembly (e.g., the second housing of the second connector assembly). The CPA device is configured to ensure proper mechanical and / or electrical connection between two corresponding connector assemblies (e.g., the housings of the first and second connector assemblies). The CPA device may include a readable and / or scannable indicia that is obscured until proper mechanical and / or electrical connection between two corresponding connector assemblies and the CPA therebetween is obtained.
[0086] For example, one implementation of a connector assembly and CPA device are shown in FIGS. 1-26C. First connector assembly 10 is a two-barcode system that is movable between a pre-lock position and a fully-locked position to respectively obscure or reveal two readable indicia. The first connector assembly 10 includes a housing 100 and a connector position assurance (CPA) device 200.
[0087] FIGS. 1-7 show various views of the housing 100. The housing 100 of the first connector assembly 10 is a male-side housing for a male connector assembly. The housing 100 is couplable to a female connector assembly having a female-side housing. However, in other implementations, the housing of the first connector assembly may be a female-side housing for a female connector assembly that is couplable to a male-side housing of a male-side assembly.
[0088] The housing 100 includes non-conductive material(s) and is generally configured to house and retain an electrical terminal. In the implementation shown, the housing 100 houses a male terminal. The housing 100 includes a first end 102, a second end 104, at least one side wall 110, a lock box 120 defining a CPA receiver 140, at least one snap-fit protrusion 150, a first cover 160, and a second cover 170.
[0089] The first end 102 and the second end 104 are opposite and spaced apart from each other along a longitudinal axis 101. The first end 102 is the “front end” or the “connection end” that is configured to interact and connect with a corresponding second connector assembly. The second end 104 is the “back end” that is configured to receive a portion of a wire or other electrical connection to a terminal housed within the first connector assembly 10.
[0090] The at least one side wall 110 is arranged along a longitudinal axis 101. As shown in FIG.5, the at least one side wall 110 extends between the first end 102 and the second end 104. The at least one side wall 110 includes a front portion 112 integrally formed with a back portion 114.MCC Docket No. 11694-117WO1
[0091] The front portion 112 of the at least one side wall 110 includes the first end 102 of the housing 100 and extends towards the second end 104 to the back portion 114. The front portion 112 includes a plurality of side walls approximating a rectangular prism shape, as shown in FIGS.1 and 6. A cross-sectional shape of the side wall of the front portion 112 taken in a plane perpendicular to the longitudinal axis 101 is substantially square-shaped.
[0092] The back portion 114 of the at least one side wall 110 includes the second end 104 of the housing 100 and extends toward the first end 102 to the front portion 112. The back portion 114 is substantially cylindrical such that a cross-sectional shape of the side wall of the back portion 114 taken in a plane perpendicular to the longitudinal axis 101 is substantially circular, as shown in FIGS. 2 and 7.
[0093] Referring to FIG. 1, the at least one side wall 110 includes a first side 106 and a second side 108 opposite and spaced apart from the first side 106 in a first direction perpendicular to the longitudinal axis 101. The at least one side wall 110 further includes a third side 116 and a fourth side 118 opposite and spaced apart from the third side 116 in a second direction perpendicular to both the longitudinal axis 101 and the first direction.
[0094] The lock box 120 extends from the first side 106 of the at least one side wall 110. The lock box 120 includes a first wall 122 and a second wall 124 each extending outward from the first side 106 of the at least one side wall 110 parallel to the first direction. The first wall 122 is spaced apart from the second wall 124 in a direction parallel to the second direction. Each of the first wall 122 and the second wall 124 also extend along the first side 106 from the first end 102 of the housing 100 towards the second end 104 in a direction parallel to the longitudinal axis 101. Each of the first wall 122 and the second wall 124 are substantially planar and are disposed on the front portion 112 of the at least one side wall 110 extending up to at least an interface with the back portion 114.
[0095] The lock box 120 further includes an outer wall 126 that extends between the outer edges of the first wall 122 and the second wall 124. The outer wall 126 is perpendicular to the first wall 122 and the second wall 124. The first wall 122, the second wall 124, and the outer wall 126 define a CPA receiver 140. Specifically, as shown in FIG. 6, an inner surface 132 of the first wall 122, an inner surface 134 of the second wall 124, and an inner surface 127 of the outer wall 126 define the CPA receiver 140. The CPA receiver 140 is further defined by the first side 106 of the at least one side wall 110 from which the first wall 122 and the second wall 124 extend.MCC Docket No. 11694-117WO1
[0096] The CPA receiver 140 defines a first opening 142 defined at a first end of the lock box 120 that is adjacent to (e.g., coincident with) the first end 102 of the housing 100. As shown in FIG. 6, the first opening 142 is substantially planar and rectangular as viewed in a cross-sectional plane that is perpendicular to the longitudinal axis 101.
[0097] As shown in FIG. 2, the CPA receiver 140 further defines a second opening 144 defined on a second end of the lock box 120 opposite from the first end of the lock box 120 in a direction parallel to the longitudinal axis 101. The second opening 144 is substantially rectangular as viewed in a cross-sectional plane that is perpendicular to the longitudinal axis 101, but includes a more complex geometry than the first opening 142, as is described further herein.
[0098] The inner surface 132 ofthe firstwall 122 further includes a first projection 128 extending inward from the inner surface 132 into the CPA receiver 140. The first projection 128 defines a first lateral retainer 130. The first lateral retainer 130 is configured to receive a snap-fit element, as further described herein. The inner surface 134 of the second wall 124 further includes a second projection 129 extending inward from the inner surface 134 into the CPA receiver 140. The second projection 129 defines a second lateral retainer 131. The second lateral retainer 131 is configured to receive a snap-fit element, as further described herein.
[0099] As shown in FIGS. 6 and 7, the housing 100 further includes the at least one snap-fit projection 150 coupled to and extending from the first side 106 of the at least one side wall 110. The at least one snap-fit protrusion 150 is disposed within the CPA receiver 140. As shown in FIGS. 1, 3, and 6, the housing 100 further includes the first cover 160 extending across a portion of the CPA receiver 140. In the implementation of the housing 100 shown in FIGS. 1-7, the at least one snap-fit protrusion 150 and the first cover 160 are integrally formed with each other (see e.g., FIG. 6). However, in other implementations, the snap-fit protrusion may extend from the at least one side wall independently from the first cover.
[0100] A first connection 152 and a second connection 154 each protrude from the first side 106 of the at least one side wall 110 within the CPA receiver 140. The first connection 152 is closer to the first wall 122, and the second connection 154 is closer to the second wall 124. Each of the first connection 152 and the second connection 154 extend away from the first side 106 of the at least one side wall 110 towards the inner surface 127 of the outer wall 126.
[0101] A first arm 156 is coupled to the first connection 152 and includes a first portion and a second portion. The first portion of the first arm 156 extends in a direction substantially parallelMCC Docket No. 11694-117WO1to the longitudinal axis 101. A second arm 158 is coupled to the second connection 154 and includes a first portion and a second portion. The first portion of the second arm 158 extends in a direction substantially parallel to the longitudinal axis 101. The first portion of first arm 156 and the first portion of the second arm 158 each extend towards the first end 102 of the housing 100 to terminate in a first end. Thus, the first end of the first arm 156 and the first end of the second arm 158 are disposed closer to the first opening 142 of the CPA receiver 140 than their respective connections 152, 154.
[0102] The at least one snap-fit protrusion 150 is coupled to and extends between the first ends of the first and second arms 156, 158. Specifically, the at least one snap-fit protrusion 150 extends from the first end of the first arm 156 to the first end of the second arm 158 in a direction substantially perpendicular to each of the first and second arms 156, 158 (e.g., a direction parallel to the second direction). The at least one snap-fit protrusion 150 includes a first surface 159 on a side of the at least one snap-fit protrusion 150 closer to the first opening 142. The first surface 159 of the at least one snap-fit protrusion 150 is configured to engage with a portion of the CPA device 200 and / or the female-side housing of the female connector assembly, as further described herein.
[0103] The at least one snap-fit protrusion 150 may be cantilevered from the first and second connections 152, 154 such that the at least one snap-fit protrusion 150 is bendable in a direction towards and / or away from the first side 106 of the at least one side wall 110. The at least one snap-fit protrusion 150 may include one or more rounded or chamfered edges facilitating engagement with the CPA device 200 and / or the female-side housing of the female connector assembly, as further described herein.
[0104] The second portion of the first arm 156 and the second portion of the second arm 158 extend in a direction away from the at least one snap-fit protrusion 150 and towards the second opening 144 of the CPA receiver 140. The second portions of the first arm 156 and the second arm 158 each extend at an angle an angle greater than 0 degrees (e.g., greater than 0 degrees to less than or equal to 15 degrees) relative to the first portions of the first arm 156 and the second arm 158, respectively. The second portions of the first arm 156 and the second arm 158 extend to a second end of the respective first arm 156 and second arm 158 opposite from the first ends of the first portions. Thus, the second ends of the arms 156, 158 are closer to the inner surface 127 of the outer wall 126 than the first ends of the arms 156, 158.MCC Docket No. 11694-117WO1
[0105] The first cover 160 is coupled to and extends between each of the second end of the first arm 156 and the second end of the second arm 158 in a direction parallel to the second direction. The first cover 160 and the second ends of the arms 156, 158 are disposed within the CPA receiver 140, but the first cover 160 and the second ends of the arms 156, 158 are not covered by the outer wall 126 of the lock box 120. The outer wall 126 defines an opening 162 aligned with the first cover 160 and a portion of the arms 156, 158. Thus, the first cover 160 is visible from outside the lock box 120 in a direction parallel to the first direction (e.g., facing the first side 106 of the at least one side wall 110).
[0106] The first cover 160 extends in a direction substantially parallel to the outer wall 126 and the first side 106 of the at least one side wall 110. The first cover 160 also extends towards the first opening 142 of the CPA receiver 140. The first cover 160 is positioned within the opening 162 of the outer wall 126 to cover a radially inward portion of the CPA receiver 140.
[0107] The second cover 170 is disposed on the second side 108 of the at least one side wall 110 on the back portion 114 of the at least one side wall 110. The second cover 170 is diametrically opposed to the lock box 120 with respect to the longitudinal axis 101. The second cover 170 extends between a first arm 172 and a second arm 174 in a direction parallel to the second direction. The first arm 172 and the second arm 174 extend away from the back portion 114 of the at least one side wall HO onthe second side 108 of the at least one side wall 110 (e.g., in a direction parallel to the first direction). The first arm 172 and the second arm 174 are spaced apart from each other in a direction parallel to the second direction.
[0108] The second cover 170 is spaced apart from the second side 108 of the at least one side wall 110 by the arms 172, 174. A second CPA receiver 175 is defined by the second cover 170, the second side 108 of the at least one side wall 110, and the arms 172, 174. The CPA receiver 175 defines an opening 176.
[0109] The housing 100 further includes one or more alignment ribs. For example, the third side 116 of the at least one side wall 110 includes a first alignment rib 180 and a second alignment rib 181 , as shown in FIG. 1. The alignment ribs 180, 181 extend outwardly from the third side 116 in a direction parallel to the second direction. The first alignment rib 180 is spaced apart from the second alignment rib 181 in a direction parallel to the first direction.
[0110] The fourth side 118 of the at least one side wall 110 that is opposite from the third side 116 in the second direction also includes alignment ribs substantially similar to the alignment ribsMCC Docket No. 11694-117WO1on the third side 116. As shown in FIG. 2, athird alignment rib 182 and a fourth alignment rib 183 extend outwardly from the fourth side 118 in a direction parallel to the second direction. The third alignment rib 182 is spaced apart from the fourth alignment rib 183 in a direction parallel to the first direction.
[0111] Each of the alignment ribs 180-183 are disposed on the back portion 114 of the at least one side wall 110. Each alignment rib 180-183 extends from the second end 104 of the housing at least to the interface with the front portion 112. Each alignment rib 180-183 extends parallel to each other in an axial direction parallel to the longitudinal axis 101. The alignment ribs 180-183 provide a guide for the alignment and insertion of the CPA device 200, as further described herein.
[0112] As shown in FIGS. 1, 2, and 6, the at least one side wall 110 of the housing 100 further defines a terminal receiver 190 on a radially inward side of the side wall 110. As shown in FIGS.1 and 6, a terminal retainer 192 is disposed within the terminal receiver 190. In general, the terminal retainer 192 is configured to receive and couple to an electrical terminal (e.g., a squareshaped male terminal) and its associated components (e.g., a square-shaped male terminal housing). Connection of a terminal to the terminal retainer 192 may be facilitated by snap-fit elements and clips extending from a portion of the terminal retainer 192.
[0113] FIGS. 8-13 show various views of the connector position assurance (CPA) device 200. The CPA device 200 includes non-conductive material(s) and is generally configured to couple to the housing 100 to ensure a proper coupling and connection of the first connector assembly 10. For example, in the implementation shown, the CPA device 200 is configured to couple to a maleside housing for a male connector assembly. The CPA device 200 is further configured to couple to a female connector assembly having a female-side housing. Thus, the CPA device 200 is configured to ensure proper connection between a male and a female connector assembly and their respective housings and electrical terminals.
[0114] The CPA device 200 includes a main body 210, a locking tab 230 with a first readable indicia 270, and an indicator tab 250 with a second readable indicia 272. The main body 210 is a substantially cylindrical main body 210 extending around a longitudinal axis 201. The main body 210 further includes a first end 202 and a second end 204 opposite and spaced apart from the first end 202 in an axial direction parallel to the longitudinal axis 201. The main body 210 defines a primary opening 209 extending between the first end 202 and the second end 204 along the longitudinal axis 201.MCC Docket No. 11694-117WO1
[0115] The main body 210 includes at least a first side 206 and a second side 208 opposite and spaced apart from the first side 206 across the primary opening 209. Thus, the first side 206 is diametrically opposed to the second side 208. Furthermore, the main body 210 includes a third side 216 and a fourth side 218 opposite and spaced apart from the third side 216. Thus, the third side 216 is diametrically opposed to the fourth side 218. The third side 216 is disposed in between the first side 206 and the second side 208 (e.g., the third side 216 is offset 90 degrees from each of the first side 206 and the second side 208 about the longitudinal axis 201). The fourth side 218 is disposed in between the second side 208 and the first side 206 (e.g., the fourth side 218 is offset 180 degrees from the third side 216 and 90 degrees from each of the first side 206 and the second side 208).
[0116] The main body 210 includes an outer surface 212 facing radially outward from the longitudinal axis 201. The main body 210 includes an inner surface 214 facing radially inward towards the longitudinal axis 201. The outer surface 212 and the inner surface 214 extend between the first end 202 and the second end 204 in the axial direction.
[0117] The inner surface 214 defines the primary opening 209 of the CPA device 200 that extends between the first end 202 and the second end 204 of the main body 210. The inner surface 214 further defines a first alignment notch 224 on the third side 216 of the main body 210 and a second alignment notch 226 on the fourth side 218 of the main body 210, as shown in FIG. 10. The first alignment notch 224 and the second alignment notch 226 are substantially rectangular-shaped cutouts in the primary opening 209 that are alignable with the alignment ribs 180-183 of the housing 100.
[0118] As shown in FIG. 12, The main body 210 further defines at least one drain hole 280 extending radially through from the inner surface 214 to the outer surface 212. The at least one drain hole 280 extends through the first side 206 of the main body 210. The at least one drain hole 280 may provide an escape for excess liquid trapped on a portion of the CPA device 200.
[0119] Referring back to FIG. 8, a first flange 220 extends radially outward from the first end 202 of the main body 210. A second flange 222 extends radially outward from the second end 204 of the main body 210. Each of the first flange 220 and the second flange 222 include inner and outer surfaces that are oriented substantially perpendicular to the longitudinal axis 201. The first flange 220 and the second flange 222 surfaces can be points of contact for a user interacting with the CPA device 200, as further described below.MCC Docket No. 11694-117WO1
[0120] The locking tab 230 is disposed on the first side 206 of the main body 210. As shown in FIGS. 8, 11, and 12, the locking tab 230 extends away from the first end 202 and the first flange 220 in the axial direction.
[0121] Referring to FIG. 8, the locking tab 230 includes a fixed end 232 coupled to the main body 210 and a distal or free end 234 spaced apart from the fixed end 232 in the axial direction. Thus, the locking tab 230 forms a cantilevered member wherein the free end 234 is bendable either away from or towards the longitudinal axis 201. The locking tab 230 includes an outer surface 235 facing radially outward relative to the longitudinal axis 201. The outer surface 235 extends from the fixed end 232 to the free end 234 of the locking tab 230.
[0122] The free end 234 of the locking tab 230 includes a snap-fit clip 236. The snap-fit clip 236 extends radially inward from the free end 234 of the locking tab 230. As shown in FIG. 11, a locking space 238 is defined between the snap-fit clip 236 and a radially inward surface of the locking tab 230 opposite the fixed end 232. The snap-fit clip 236 and the locking space 238 are configured to interact with the at least one snap-fit protrusion 150 of the housing 100. The snap-fit clip 236 may include rounded, chamfered, or angled edges or surfaces to facilitate movement and interaction of the locking tab 230 with other elements of the first connector assembly 10 and / or the female-side housing of the female connector assembly.
[0123] The first readable indicia 270 is disposed on the outer surface 235 of the locking tab 230. The first readable indicia 270 may include a barcode, QR code, words, letters, or any other readable markings etched, laser-etched, stuck to, or formed on the fixed end 232 of the locking tab 230. The first readable indicia 270 is scannable in a scanning direction that is substantially perpendicular to the outer surface 235 of the locking tab 230.
[0124] The CPA device 200 further includes at least one lateral clip on the first side 206 of the main body 210. Specifically, the CPA device 200 includes a first lateral clip 240 and a second lateral clip 242 extending from the first side 206 of the main body 210 in the axial direction. The first lateral clip 240 is spaced apart from the locking tab 230 closer to the third side 216 of the main body 210. The second lateral clip 242 is spaced apart from the locking tab 230 closer to the fourth side 218 of the main body 210. The free end 234 of the locking tab 230 extends further away from the first end 202 of the main body 210 than a free end of each of the first lateral clip 240 and the second lateral clip 242. The first lateral clip 240 is engageable with the first lateral retainer 130, and the second lateral clip 242 is engageable with the second lateral retainer 131.MCC Docket No. 11694-117WO1
[0125] The second side 208 of the main body 210 defines the indicator tab 250. Slots 252, 254 on each side of the indicator tab 250 are defined in the second side 208 and extend from the first end 202 of the main body 210 toward to the second end 204. The indicator tab 250 is diametrically opposed from the locking tab 230 in the implementation shown.
[0126] The first flange 220 does not extend along the portion of the main body 210 defining the slots 252, 254 and the indicator tab 250. Thus, the first end 202 of the main body 210 defining the slots 252, 254 is open to allow engagement of the indicator tab 250 with the housing 100. The first slot 252 is closer to the third side 216, and the second slot 254 is closer to the fourth side 218 of the main body 210.
[0127] The indicator tab 250 includes an outer surface 256 facing radially outwardly from the main body 210 and the longitudinal axis 201. The outer surface 256 includes the second readable indicia 272 disposed therein. The second readable indicia 272 is substantially similar to the first readable indicia 270 and may provide the same or similar information when scanned. The second readable indicia 272 is scannable in a second scanning direction that is perpendicular to the outer surface 256.
[0128] The first connector assembly 10 is generally movable between a pre-lock position and a fully-locked position. The pre-lock position may indicate that the housing 100 and the CPA device 200 are not yet fully engaged with or coupled to each other. The pre-lock position may further indicate that an electrical terminal of the first connector assembly 10 (e.g., a male terminal coupled to the housing 100) is not yet fully engaged with or properly coupled to a corresponding second connector assembly (e.g., a female terminal coupled to a female-side housing). FIGS. 14-21 show various views of the first connector assembly 10 in the pre-lock position.
[0129] The housing 100 and the CPA device 200 are engageable with each other such that the CPA device 200 wraps around a substantial portion of the at least one side wall 110 of the housing 100. For example, the primary opening 209 of the CPA device 200 may be axially aligned with the back portion 114 of the at least one side wall 110 on the second end 104 of the housing 100. Furthermore, the locking tab 230 on the first side 206 of the CPA device 200 is aligned with, or disposed on the same side as, the lock box 120 on the first side 106 of the at least one side wall 110. The first end 202 of the main body 210 is then inserted onto the second end 104 of the at least one side wall 110 and moved axially towards the first end 102 of the housing 100, which may beMCC Docket No. 11694-117WO1defined as the “coupling direction”. Thus, the longitudinal axis 101 of the housing 100 may be coaxial with the longitudinal axis 201 of the CPA device 200.
[0130] As shown in FIG. 14, the first alignment notch 224 of the CPA device 200 receives the first alignment rib 180 and the second alignment rib 181 on the third side 116 of the at least one side wall 110. Furthermore, the second alignment notch 226 of the CPA device 200 receives the third alignment rib 182 and the fourth alignment rib 183 on the fourth side 118 of the at least one side wall 110. The alignment notches 224, 226 and the corresponding alignment ribs 180-183 keep the CPA device 200 properly radially aligned with the housing 100 as the CPA device 200 moves in the coupling direction.
[0131] When moving the CPA device 200 in the coupling direction towards the pre-lock position, the locking tab 230 of the CPA device 200 enters the second opening 144 of the CPA receiver 140. In the pre-lock position, a substantial portion of the first lateral retainer 130 is disposed within the CPA receiver 140.
[0132] In the pre-lock position, the first lateral clip 240 of the CPA device 200 engages with the first lateral retainer 130 of the housing 100. Specifically, as shown in FIG. 15 and FIG. 19, the first lateral clip 240 moves in the coupling direction to engage with the first projection 128, causing the free end of the first lateral clip 240 to deform and snap into place within the first lateral retainer 130. Similarly, the second lateral clip 242 engages with the second projection 129, causing the free end of the second lateral clip 242 to deform and snap into place within the second lateral retainer 131. Thus, in the pre-lock position, the CPA device 200 is locked into the housing 100. The CPA device 200 cannot easily be moved opposite from the coupling direction to disengage from the housing 100 once the first connector assembly 10 is in the pre-lock position.
[0133] Although the CPA device 200 is locked onto the housing 100 in the pre-lock position, the snap-fit clip 236 and the at least one snap-fit protrusion 150 are not fully engaged in the pre-lock position. As shown in FIGS. 20 and 21, the snap-fit clip 236 on the free end 234 of the locking tab 230 is disposed adjacent to, and may abut, the at least one snap-fit protrusion 150. Specifically, the snap-fit clip 236 is disposed in between the first arm 156 and the second arm 158 on a side of the at least one snap-fit protrusion 150 opposite from the first surface 159. Thus, the locking space 238 of the locking tab 230 is empty in the pre-lock position.
[0134] In the pre-lock position, the CPA device 200 is blocked from moving axially to the fully-locked position by the interference between the snap-fit clip 236 of the locking tab 230 and the atMCC Docket No. 11694-117WO1least one snap-fit protrusion 150. The at least one snap-fit protrusion 150 and the snap-fit clip 236 include substantially parallel outer surfaces at their interface with each other, which prevents the snap-fit clip 236 from moving past the at least one snap-fit protrusion 150.
[0135] In the pre-lock position, the first cover 160 obscures at least a portion of the first readable indicia 270. Specifically, as shown in FIG. 17, a portion of the first readable indicia 270 disposed on the outer surface 235 of the locking tab 230 is blocked by the first cover 160 of the housing 100. The first readable indicia 270 is unreadable by a scanner in the scanning direction through the opening 162 in the outer wall 126 of the lock box 120 (e.g., a direction perpendicular to the outer surface 235) when the first connector assembly 10 is in the pre-lock position.
[0136] Furthermore, in the pre-lock position, the second readable indicia 272 on the indicator tab 250 is obscured by the second cover 170 of the housing 100. As shown in FIG. 15 and FIG. 18, the indicator tab 250 enters the second CPA receiver 175 via the opening 176. The first arm 172 is disposed within the first slot 252 of the CPA device 200, and the second arm 174 is disposed within the second slot 254 of the CPA device 200. Thus, the indicator tab 250 is disposed within the second CPA receiver 175. The second cover 170 extends over and obscures at least a portion of the second readable indicia 272. The second readable indicia 272 is unreadable by a scanner in the scanning direction (e.g., perpendicular to the second readable indicia 272) when the first connector assembly 10 is in the pre-lock position.
[0137] Successful scanning of the first readable indicia 270 or the second readable indicia 272 may confirm proper mechanical and / or electrical connection between the first connector assembly 10 and a second connector assembly (e.g., the female connector assembly). Successful scanning of the first readable indicia 270 and the second readable indicia 272 may further communicate and confirm the proper mechanical and / or electrical connection with a scanner or a database associated with the scanner. Therefore, it is desirable that proper mechanical and / or electrical actually be achieved before a successful scanning of the first readable indicia 270 or the second readable indicia 272.
[0138] The pre-lock position of the first connector assembly 10 thus prevents scanning of the first readable indicia 270 or the second readable indicia 272 before proper mechanical and / or electrical connection of the first connector assembly 10 and a second connector assembly. Scanning prevention may be used, for example, before the first connector assembly 10 and any associated electrical terminal(s) thereof are properly coupled to a second connector assembly andMCC Docket No. 11694-117WO1any associated electrical terminal(s) thereof. For example, during the assembly of a connector system, the first readable indicia 270 and the second readable indicia 272 may be obscured so that inadvertent scanning is prevented. Once the first connector assembly 10 is in the fully-locked position, the readable indicia is exposed and able to be scanned.
[0139] FIGS. 22-26C show various views of the first connector assembly 10 in the fully-locked position, with the exception of FIG. 26A, which shows the first connector assembly 10 in a transition position between the pre-locked and the fully-locked positions. To move the first connector assembly 10 from the pre-locked position to the fully-locked position, the CPA device 200 is moved further axially in the coupling direction with respect to the housing 100.
[0140] In order to move from the pre-locked position to the fully-locked position, the housing 100 of the first connector assembly 10 first engages with a second connector assembly and the housing thereof. For example, FIG. 26B shows a cross section of the fully-locked position wherein the first connector assembly 10 engages with a second housing 500. As shown, the second housing 500 is the female-side housing a female connector assembly that is couplable to the first connector assembly 10 that is the male connector assembly. The second housing 500 retains an electrical terminal configured to mechanically and electrically connect to an electrical terminal retained by the housing 100. Only when the mechanical and electrical connection between the terminals is complete can the CPA device 200 move to the fully-locked position to reveal the readable indicia.
[0141] As shown in FIG. 26B, the second housing 500 includes an outer arm 502 having a free end with a rounded surface 504 extending radially outwardly from the free end of the outer arm 502. The free end of the outer arm 502 enters the CPA receiver 140 from the first opening 142 on the first end 102 of the housing 100. The rounded surface 504 of the outer arm 502 engages with the first surface 159 of the at least one snap-fit protrusion 150 to bend the at least one snap-fit protrusion 150 radially outward (e.g., away from the first side 106 of the at least one side wall 110 and away from the longitudinal axis 101). As the at least one snap-fit protrusion 150 bends outward, the free end of the outer arm 502 and the entire second housing 500 moves axially with respect to the housing 100.
[0142] Furthermore, the rounded surface 504 engages with the snap-fit clip 236, which is coupled to the housing 100 in the pre-lock position. Thus, the rounded surface 504 engages with the snap-fit clip 236 to bend the free end 234 of the locking tab 230 radially outward. Once the free end of the outer arm 502 moves into the CPA receiver 140 far enough to deform the locking tab 230, theMCC Docket No. 11694-117WO1snap-fit clip 236 is in a deformed state with the snap-fit clip 236 engaged with a radially outward portion of the rounded surface 504, as shown in FIG. 26A. Specifically, FIG. 26A shows a transition between the pre-locked position and the fully-locked position wherein the free end 234 of the locking tab 230 is bent radially outward by the rounded surface 504 of the outer arm 502 of the second housing 500.
[0143] To move the first connector assembly 10 and the second housing 500 into the fully-locked position, the CPA device 200 is moved axially in the coupling direction with respect to the housing 100 and the second housing 500. The deformation of the snap-fit clip 236 by the rounded surface 504 of the outer arm 502 allows the snap-fit clip 236 to move up and over the at least one snap-fit protrusion 150. Thus, axial movement of the CPA device 200 in the coupling direction allows the snap-fit clip 236 to snap back into place radially inward, as shown in FIGS. 26B and 26C. In the fully-locked position, the snap-fit clip 236 is closer to the first end 102 of the housing 100 than either the at least one snap-fit protrusion 150 or the rounded surface 504. Thus, in the fully-locked position, as shown in FIG. 26B, the at least one snap-fit protrusion 150 and the free end of the outer arm 502 with the rounded surface 504 are disposed within the locking space 238 defined by the locking tab 230.
[0144] Because the snap-fit clip 236 of the CPA device 200 is moved into the fully-locked position by the rounded surface 504 of the second housing 500, the CPA device 200 is prevented from revealing the readable indicia before the second housing 500 of the second connector assembly is properly engaged with the housing 100 of the first connector assembly 10. The CPA device 200 can only move in the coupling direction and into the fully-locked state after the second connector assembly and the terminal thereof is mechanically and electrically coupled to the terminal of the first connector assembly 10.
[0145] In the fully-locked position, the first readable indicia 270 on the locking tab 230 is moved axially such that the first cover 160 no longer obscures the first readable indicia 270. As shown in FIG. 22, the first readable indicia 270 is scannable in the scanning direction through the opening 162 in the outer wall 126 of the lock box 120 when the first connector assembly 10 is in the fully-locked position.
[0146] In the fully-locked position, the second readable indicia 272 on the indicator tab 250 is moved axially such that the second cover 170 no longer obscures the second readable indicia 272. As shown in FIG. 25, the second readable indicia 272 is scannable in a scanning directionMCC Docket No. 11694-117WO1perpendicular to the second readable indicia 272 when the first connector assembly 10 is in the fully-locked position.
[0147] The arrangement of the first connector assembly 10 provides that the first readable indicia 270 and the second readable indicia 272 are only readable (e.g., via a scanner) when in the fully-locked position. Thus, only when the first connector assembly 10 (and an electrical terminal thereof) is fully and properly secured to a second connector assembly (and a corresponding electrical terminal thereof) will the CPA device 200 be properly positioned relative to the housing 100 to reveal the first readable indicia 270 and the second readable indicia 272 for scanning. This arrangement prevents unwanted or premature scanning before proper mechanical and / or electrical connection is achieved.
[0148] A third connector assembly 20 and associated elements is shown in FIGS. 27-51, according to another implementation. The third connector assembly 20 is substantially similar to the first connector assembly 10 of FIGS. 1-26C, except as described below. The third connector assembly 20 may be a male-side housing that is couplable to a female-side housing of a corresponding fourth connector assembly, or vice versa.
[0149] The third connector assembly 20 is a four-barcode system, in contrast to the two-barcode system of the first connector assembly 10 of FIGS. 1-26C. Specifically, the first connector assembly 10 of FIGS. 1-26C includes two readable indicia on opposite sides of the first connector assembly 10 (e.g., 180 degrees apart from each other). In contrast, the third connector assembly 20 of FIGS. 27-51 includes four readable indicia on opposite sides of the third connector assembly 20 (e.g., 90 degrees apart from each other). Thus, the third connector assembly 20 provides additional opportunities for a scanner and / or a user to verify proper mechanical and / or electrical connection of the third connector assembly 20. However, in other implementations, the disclosed connector assembly may include a different number of barcodes / readable indicia and corresponding covers than shown (e.g., 3, 5, 6, 7, 8, 9, or more readable indicia and corresponding covers). In other implementations, one barcode or readable indicia may be obscured at least in part by more than one cover. In other implementations, more than one barcode or readable indicia may be obscured at least in part by a single cover.
[0150] The third connector assembly 20 is movable between a pre-lock position and a fully-locked position to respectively obscure or reveal four readable indicia in a manner similar to thatMCC Docket No. 11694-117WO1of the first connector assembly 10. The third connector assembly 20 includes a housing 300 and a CPA device 400.
[0151] FIGS. 27-36 show various views of the housing 300, according to the second implementation. The housing 300 is substantially similar to the housing 100 of FIGS. 1-26C. Therefore, an exhaustive set of reference numbers is not repeated. Like reference numbers denote like elements (e.g., the longitudinal axis 101 corresponds to a similar longitudinal axis 301).
[0152] The housing 300 includes a side wall arrangement 310 that includes a first side 306, a second side 308, athird side 316, and a fourth side 318. The housing 300 includes a lock box 320 on the first side 306 that defines a CPA receiver 340. The housing 300 includes a first cover 360 extending across a portion of the CPA receiver 340. As shown in FIG. 29 and FIG. 31, the housing 300 includes a second cover 370 on the second side 308. The second cover 370 defines a second CPA receiver 375.
[0153] In contrast to the housing 100 ofthe first connector assembly 10, the housing 300 includes a third cover 396 defining a third CPA receiver 395 and a fourth cover 398 defining a fourth CPA receiver 397.
