[0007] While the present disclosure may be susceptible to embodiments in different forms, specific embodiments are described in detail herein with the understanding that the present disclosure is to be considered as an exemplification of the principles of the present disclosure and is not intended to limit the disclosure to what is illustrated and described herein. Thus, unless otherwise indicated, features disclosed herein may be combined to form additional combinations not otherwise shown for purposes of brevity. It will be further understood that in some embodiments, one or more elements illustrated as examples in the drawings may be eliminated and / or replaced with alternative elements within the scope of the present disclosure.

[0008] As illustrated in Figures 1 and 2, the high speed connector system 20 includes a male connector 22 and a female connector 222 configured to removably mate with one another. The male connector 22 has a male housing 26, an independent secondary lock 28 movable relative to the male housing 26, and a male module 30 (see Figure 4) removably mounted within the male housing 26. The independent secondary lock 28 assists in positioning and retaining the male module 30 within the male housing 26. The female connector 222 has a female housing 226, an independent secondary lock 228 movable relative to the female housing 226, a female module 230 removably mounted within the female housing 226, a connector position assurance device 232, and a slider 234. The independent secondary lock 228 assists in positioning and retaining the female module 230 within the female housing 226. The modules 30, 230 are configured to mate together during mating of the male connector 22 and the female connector 222 to join mating electrical terminals (not shown) housed within the modules 30, 230. A connector position assurance device 232 and a slider 234 are used to further secure the male connector 22 and the female connector 222 to one another and are not described herein.

[0009] The male connector 22 is best seen in Figures 3-7. The male housing 26 is generally formed as a block having an upper surface, a lower surface, and sides connecting the upper surface and the lower surface to one another. The male housing 26 may be formed from multiple pieces. A cavity 36 extends from a front end 26a of the male housing 26 to an enlarged male module receiving passage 38 that extends from the cavity 36 to a rear end 26b of the male housing 26 and a plurality of terminal receiving passages 40 that extend from the front end 26a of the male housing 26 to a plurality of terminal receiving passages 40 that extend from the cavity 36 to the rear end 26b of the male housing 26. The male module 30 is removably mounted within the male module receiving passages 38. Electrical terminals (not shown) are received within the terminal receiving passages 40. The electrical terminals may be attached to a wire bundle (not shown) that may be connected to a wire harness or other electrical component. The terminal-receiving passages 40 may be formed in rows and columns.

[0010] As shown in FIG. 7, the male module receiving passage 38 has a top wall surface 42, a bottom wall surface 44, and opposing side wall surfaces 48, 50 extending between the top wall surface 42 and the bottom wall surface 44. The top wall surface 42 and the bottom wall surface 44 are parallel to one another, and the side wall surfaces 48, 50 are parallel to one another and perpendicular to the top wall surface 42 and the bottom wall surface 44. A central axis 46 is defined between the front and rear ends of the male module receiving passage 38. A portion of each side wall surface 48, 50 has a recess 52 (see FIG. 6) therein having upper and lower walls 54 extending perpendicular to the central axis of the male module receiving passage 38, and a vertically extending flat side wall 56. The recess 52 may extend from the front end 26a of the male housing 26. A stop wall 58 (see FIG. 6) extends partially into the male module receiving passage 38 at the front end of the male module receiving passage 38 to limit the size of the male module receiving passage 38. The stop wall 58 is immediately forward of the recess 52.

[0011] An opening 60 extends through the male housing 26 from a top surface of the male housing 26 adjacent the rear end 26b of the male housing 26 and intersects with the male module receiving passage 38. A slot 62 extends through the male housing 26 from a top surface of the male housing 26 and intersects with the male module receiving passage 38. The slot 62 is forward of the opening 60.

[0012] The independent secondary lock 28 seats in the slot 62 and has an opening that aligns with the male module receiving passage 38 of the male housing 26. The independent secondary lock 28 has a protrusion 64 (see FIGS. 6 and 7) that is configured to extend into the opening in the independent secondary lock 28 and extend into the male module receiving passage 38. The independent secondary lock 28 also has an opening that aligns with the terminal receiving passage 40 of the male housing 26. As the independent secondary lock 28 moves relative to the male housing 26, the protrusion 64 moves into the male module receiving passage 38 to engage the male module 30 to prevent withdrawal of the male module 30 from the male housing 26, or moves out of the male module receiving passage 38 to disengage from the male module 30 to allow withdrawal of the male module 30 from the male housing 26.

[0013] The male module 30 is best seen in Figure 9. The male module 30 has a housing 66 formed from a top wall 70, an opposed bottom wall 72, and opposed side walls 74, 76 extending therebetween, which walls form a passageway 78 that extends from the front end 30a of the male module 30 to the rear end 30b of the male module 30. The outer contour of the housing 66 may be generally the same shape as the inner contour of the male module receiving passage 38, but the outer contour of the housing 66 is smaller than the inner contour of the male module receiving passage 38, thereby forming gaps 80 (see FIG. 7) around the entire circumference of the housing 66 between a top wall 70 of the housing 66 and the top wall surface 42 of the male module receiving passage 38, between a bottom wall 72 of the housing 66 and the bottom wall surface 44 of the male module receiving passage 38, between a side wall 74 of the housing 66 and the side wall surface 48 of the male module receiving passage 38, and between a side wall 76 of the housing 66 and the side wall surface 50 of the male module receiving passage 38. In an embodiment, as shown in FIG. 9, the front portion 66a of the housing 66 has a generally cylindrical outer contour and the rear portion 66b of the housing 66 has a generally rectangular prism outer contour. The front end 30a may have a chamfer 82 on its outer surface.

[0014] A depressible, longitudinally extending latch 84 is formed in top wall 70. Latch 84 has an elongated arm 86 that is joined at its forward end to top wall 70 and an enlarged head 88 at the rear end of arm 86.

[0015] A plurality of rounded projections 90, 92, 94, 96 that form ball joints extend from the housing 66. A pair of projections 90 extend outwardly from the outer surface of the top wall 70 adjacent to but spaced from the rear end 30b. A projection 92 extends outwardly from the outer surface of the bottom wall 72 adjacent to but spaced from the rear end 30b. A projection 94 extends outwardly from the outer surface of the side wall 74 adjacent to but spaced from the rear end 30b. A projection 96 extends outwardly from the outer surface of the side wall 76 adjacent to but spaced from the rear end 30b. The projections 90, 92, 94, 96 may be longitudinally aligned with one another around the housing 66 and generally aligned with the head 88. A projection 90 is provided on each side of the head 88. Each projection 90, 92, 94, 96 may have a rounded outer contour and form a dome.

[0016] Longitudinally extending projections 98 extend outwardly from the side walls 74, 76 forward of the latch 84. The projections 98 are aligned with one another. Each projection 98 may have a chamfer at a front end of each projection 98 to aid in insertion of the male module 30 into the male housing 26. An opening 102 is provided through the top wall 70 forward of the latch 84 and is used to receive the projection 64 of the independent secondary lock 28.

[0017] To couple the male module 30 and the male housing 26, the front end 30a of the male module 30 is inserted through the rear end 26b of the male housing 26, with the projections 98 sliding along the sidewall surfaces 48, 50 and then seating within the recesses 52. Each recess 52 is larger than its respective projection 98, and each projection 98 extends rearwardly from its respective recess 52 to allow the projections 98 to move within the recesses 52. Once within the male housing 26, the head 88 of the latch 84 engages the top wall surface 42, deflecting the arm 86 and slightly depressing the latch 84 into the male module receiving passage 38. The head 88 slides along the top wall surface 42 until the head 88 aligns with the opening 60, which allows the arm 86 to return to its unflexed position and the head 88 can engage the rear wall 60b of the opening 60. The opening 60 is larger than the head 88. Upon entering the male housing 26, the projection 90 slides along the top wall surface 42 of the male module receiving passage 38, the projection 92 slides along the bottom wall surface 44 of the male module receiving passage 38, the projection 94 slides along the side wall surface 48 of the male module receiving passage 38, and the projection 96 slides along the side wall surface 50 of the male module receiving passage 38. When the head 88 is seated within the opening 60, the projection 90 abuts the top wall surface 42, the projection 92 abuts the bottom wall surface 44, the projection 94 abuts the side wall surface 48, and the projection 96 abuts the side wall surface 50. A front end 98a of the projection 98 is spaced from the stop wall 58 such that a gap 100 (see FIG. 8) is provided therebetween.

[0018] The engagement of the projections 90, 92, 94, 96 with the walls 42, 44, 48, 50 allows the male module 30 to be centered within the male module receiving passage 38 and to float within the male housing 26 such that the male module 30 can rotate about its central axis relative to the male housing 26. The size of the recess 52 limits rotation of the male module 30 about the central axis of the front end 30a relative to the male housing 26 by allowing only limited movement of the projection 98 therein. The stop wall 58 provides a front stop for the male module 30 and the rear wall 60b of the opening 60 with which the head 88 engages provides a rear stop for the male module 30.

[0019] The female housing 226 and separate secondary lock 228 of the female connector 222 are formed in the same manner as that of the male connector 22 (except for modifications to the housings 26, 226 that allow the connector position assurance device 232 and slider 234 to be coupled to the male connector 22 and female connector 222), and like elements are designated with the same reference numbers except for the 200 and 300 series. Details will not be repeated here.

[0020] The female module 230 is formed in the same manner as the male module 30, and like elements are designated with the same reference numerals, except for the 200 and 300 numbers. The female module 230 is best seen in FIG. 9. The female module 230 differs from the male module 30 in that the passageway 278 of the female module 230 is larger than the front portion 66a of the male module 30, and the chamfer 282 is on the outside of the front portion 66a of the female module 30. As with the male module 30, the engagement of the projections 290, 292, 294, 296 of the female module 230 with the walls 242, 244, 248, 250 of the female connector 222 allows the female module 230 to be centered within the female module receiving passageway 238, and to float within the female housing 226 such that the female module 230 can rotate about its central axis relative to the female housing 226. The size of recess 252, including gap 300, limits rotation of front end 230a of female module 230 relative to female housing 226 about the central axis by allowing only limited movement of protrusion 298 therein. Stop wall 258 provides a front stop for female module 230, and rear wall 260b of opening 260, into which head 288 engages, provides a rear stop for female module 230.

[0021] During mating, the front portion 66a of the male module 30 is pressed into and seats in the passage 278 of the female module 30, as shown in Figures 13 and 14. If the central axes of the modules 30, 230 are not aligned when the male connector 22 is inserted into the female connector 222, the modules 30, 230 rotate about the appropriate projections 90, 92, 94, 96, 290, 292, 294, 296 until the central axes of the modules 30, 230 are aligned. This allows for proper insertion of the male module 30 into the female module 230 so that the terminals therein will properly mate. The chamfer 82 aids in centering by engaging the chamfer 282 of the female module 230 so that the front end 30a of the male module 30 passes through the front end 230a of the female module 230. Electrical terminals positioned in terminal receiving passages 40 of the male connector 22 electrically couple to electrical terminals positioned in terminal receiving passages 240 of the female connector 222, and electrical terminals positioned in the male module 30 electrically couple to electrical terminals positioned in the female module 230. When the male and female connectors 22 and 322 are mated, the independent secondary locks 28, 228 are moved to seat the projections 64, 264 in the openings 102, 302, and the connector position assurance device 232 and slider 234 are engaged.

[0022] Although the module 30, 230 is shown entering through the rear 26a, 226a of the male housing 26, 226 and the latches 84, 284 are shown to accommodate this rear entry, the housing 26, 226 may be modified to allow for front entry through the front end 26a, 226a by the latches 84, 284, and the latches 84, 284 may be reversed or modified to allow for this entry. Additionally, although the latches 84, 284 are described as being on a single wall, the latches may be provided on two or more walls. Although the projections 98, 298 are shown as fixed members extending from the walls 74, 76, 274, 276, the projections 98, 298 may be formed as part of a depressible latch. Additionally, the protrusions 98, 298 may be formed in the top walls 70, 270 and bottom walls 72, 272 and the recesses 52, 252 in which the protrusions 98, 298 are repositioned accordingly.

[0023] Although specific embodiments have been illustrated and described with respect to the drawings, it is envisioned that those skilled in the art may devise various modifications without departing from the spirit and scope of the appended claims. Accordingly, it will be understood that the scope of the disclosure and the appended claims is not limited to the specific embodiments illustrated in and discussed with respect to the drawings, and that modifications and other embodiments are intended to be included within the scope of the disclosure and the appended drawings.
