[0003] With the carrier member 102 electrically connected to the plate 104 a of the ground plane 104 , the contact arm 104 b of the ground plane 104 is electrically connected to the ground contact 105 a of the paddle card 105 .

[0004] This forms a ground path from the ground shield 103a of the cable 103 to the ground contact 105a of the paddle card 105. In this case, the carrier member 102 is made of a single metal plate, and each nest portion 102a is formed by stamping and bending the single metal plate. [Prior art documents] [Patent documents]

[0026] Specific embodiments to which the present disclosure is applied will be described in detail below with reference to the drawings. However, the present disclosure is not limited to the following embodiments. In addition, the following description and drawings have been simplified as appropriate for clarity of explanation.

[0027] <First Embodiment> The connector assembly of this embodiment is suitable, for example, as a jumper connector that electrically connects a connector provided on a first board and a connector provided on a second board arranged in a server or the like.

[0028] For clarity, the following description will be given using a three-dimensional (XYZ) coordinate system, where the X-axis direction is the insertion / removal direction of the connector assembly, the Y-axis direction is the width direction of the connector assembly, and the Z-axis direction is the thickness direction of the connector assembly.

[0029] Fig. 1 is a perspective view of the connector assembly of this embodiment as seen from the +Z axis side. Fig. 2 is an exploded perspective view of the connector assembly of this embodiment as seen from the +Z axis side. Fig. 3 is a plan view of the connector assembly of this embodiment as seen from the +Z axis side, with the housing and frame omitted. Fig. 4 is a cross-sectional view taken along line IV-IV of Fig. 3.

[0030] Fig. 5 is a perspective view of the connector assembly of the present embodiment, with the housing and frame omitted, as viewed from the +Z-axis side. Fig. 6 is a perspective view of the connector assembly of the present embodiment, with the housing and frame omitted, as viewed from the -Z-axis side.

[0031] 1 to 4, the connector assembly 1 includes a paddle card 2, a ground member 3, a cable 4, a locator 5, a housing 6, and a frame 7. As shown in FIGS. 5 and 6, the paddle card 2 includes signal contacts 2a and ground contacts 2b provided on the +Z-axis side and -Z-axis side surfaces of the multilayer board.

[0032] In this case, the ground contacts 2b may be arranged so as to sandwich the signal contacts 2a in the Y-axis direction, as shown in Fig. 3. Also, for example, the signal contacts 2a and the ground contacts 2b may be aligned in the Y-axis direction. In other words, the signal contacts 2a may be arranged at approximately equal positions in the X-axis direction, and the ground contacts 2b may also be arranged at approximately equal positions in the X-axis direction.

[0033] Fig. 7 is a perspective view of the paddle card and ground member in the connector assembly of the present embodiment, as viewed from the +Z axis side. Fig. 8 is an exploded perspective view of the paddle card and ground member in the connector assembly of the present embodiment, as viewed from the +Z axis side.

[0034] 7 and 8, the grounding member 3 is disposed on the negative side of the X-axis with respect to the paddle card 2. The grounding member 3 includes a metal plate 11, a first partition member 12, and a second partition member 13. The metal plate 11 is a metal plate that is substantially parallel to the XY plane, and may have, for example, a substantially rectangular shape that is long in the Y-axis direction when viewed from the Z-axis direction.

[0035] At the end of the metal plate 11 on the positive side of the X axis, recesses 11a may be formed at a predetermined pitch in the Y axis direction, as shown in Fig. 8. In this embodiment, for example, an even number of recesses 11a are arranged in the Y axis direction according to the number of cables 4 aligned in the Y axis direction. Here, the predetermined pitch may be, for example, slightly larger than the width dimension of the cables 4 in the Y axis direction.

[0036] 3 and 4, the first partitioning member 12 and the second partitioning member 13 partition a space in which the cable 4 is disposed. The first partitioning member 12 and the second partitioning member 13 are disposed on the Z-axis + side and the Z-axis - side of the metal plate 11, respectively.

[0037] Here, as shown in Figures 5 and 6, the first partition member 12 and the second partition member 13 arranged on the +Z-axis side of the metal plate 11 and the first partition member 12 and the second partition member 13 arranged on the -Z-axis side of the metal plate 11 are in a point-symmetric relationship with an axis of symmetry that passes through the center of the connector assembly 1 in the Y-axis direction and is parallel to the X-axis. Therefore, the shape and arrangement of the first partition member 12 and the second partition member 13 arranged on the +Z-axis side of the metal plate 11 will be described as representative examples.

[0038] Figure 9 is a perspective view of a typical first partition member in the connector assembly of this embodiment, as seen from the +Z-axis side. Figure 10 is a perspective view of a typical first partition member in the connector assembly of this embodiment, as seen from the -Z-axis side. The first partition member 12 is made of a conductive material such as metal.

[0039] 9 and 10, the first partition member 12 includes a first partition wall 12a, a second partition wall 12b, a flat portion 12c, and a fixing portion 12d. The first partition wall 12a is a plate substantially parallel to the XZ plane and may have, for example, a substantially rectangular shape that is long in the X-axis direction when viewed from the Y-axis direction. The height of the first partition wall 12a in the Z-axis direction may be, for example, slightly smaller than the height of the cable 4 in the Z-axis direction.

[0040] 9 and 10, the second partition wall 12b has substantially the same shape as the first partition wall 12a. The second partition wall 12b is disposed on the negative Y-axis side of the first partition wall 12a and overlaps with the first partition wall 12a when viewed from the Y-axis direction. In this case, the distance between the negative Y-axis side surface of the first partition wall 12a and the positive Y-axis side surface of the second partition wall 12b should preferably be slightly larger than the width dimension of the cable 4 in the Y-axis direction.

[0041] As shown in Figures 9 and 10, the flat portion 12c connects the end portion of the first partition wall 12a that is on the negative Z-axis side and the negative X-axis side, and the end portion of the second partition wall 12b that is on the negative Z-axis side and the negative X-axis side.

[0042] 9 and 10, the first partitioning member 12 has a basic configuration of a substantially U-shape when viewed in the X-axis direction. The end of the first partitioning wall 12a on the +X-axis side and the end of the second partitioning wall 12b on the +X-axis side protrude from the flat portion 12c toward the +X-axis side. The flat portion 12c is a plate that is substantially parallel to the XY plane and may be, for example, substantially rectangular when viewed in the Z-axis direction.

[0043] 9 and 10, the fixing portion 12d includes a flat portion 12c, a connecting portion 12f that bends approximately 90° from the end of the flat portion 12c on the positive side of the X-axis toward the negative side of the Z-axis, and a flat portion 12e that bends approximately 90° from the end of the connecting portion 12f toward the negative side of the X-axis and is disposed approximately parallel to the flat portion 12c. The fixing portion 12d has a shape that can sandwich the metal plate 11, for example, and is approximately U-shaped when viewed from the Y-axis direction. The flat portion 12e is a plate that is approximately parallel to the XY plane and may be, for example, approximately rectangular when viewed from the Z-axis direction.

[0044] 9 and 10, flat portion 12e is disposed on the negative Z-axis side of flat portion 12c and overlaps with flat portion 12c when viewed from the Z-axis direction. The outer shape of flat portion 12e is smaller than the outer shape of flat portion 12c. The distance in the Z-axis direction between the end of flat portion 12c on the negative Z-axis side and the end of flat portion 12e on the positive Z-axis side is approximately equal to the thickness of metal plate 11 in the Z-axis direction.

[0045] 9 and 10, connecting portion 12f connects the end of flat portion 12c on the positive X-axis side to the end of flat portion 12e on the positive X-axis side. Connecting portion 12f extends in the Z-axis direction and may have, for example, a substantially rectangular shape when viewed in the X-axis direction. Furthermore, the width dimension of connecting portion 12f in the Y-axis direction is preferably smaller than the width dimension of flat portion 12e in the Y-axis direction and substantially equal to the width dimension of recess 11a of metal plate 11 in the Y-axis direction.

[0046] When the first partition wall 12a, the second partition wall 12b, and the flat portion 12c of the fixing portion 12d of the first partition member 12 are arranged on the Z-axis + side relative to the flat portion 12e of the fixing portion 12d, for example, as shown in Figures 7 and 8, the connecting portion 12f of the fixing portion 12d is inserted from the X-axis + side into the odd-numbered recess 11a of the metal plate 11 from the Y-axis + side, and the metal plate 11 is sandwiched between the flat portion 12c and the flat portion 12e of the fixing portion 12d.

[0047] As a result, as shown in Figure 7, the first partition wall 12a, the second partition wall 12b, and the flat portion 12c of the first partition member 12 are positioned on the +Z axis side of the metal plate 11, and the first partition member 12 is electrically connected to and fixed to the metal plate 11.

[0048] At this time, as shown in FIG. 4, the first partition members 12 are arranged at a pitch twice the predetermined pitch in the Y-axis direction, and the first partition walls 12a and the second partition walls 12b are repeatedly arranged at a predetermined pitch in the Y-axis direction.

[0049] As shown in FIG. 7, the first partition wall 12a and the second partition wall 12b protrude from the metal plate 11 toward the +X-axis side, and the end of the first partition wall 12a on the +X-axis side and the end of the second partition wall 12b on the +X-axis side are electrically connected to ground contacts 2b provided on the surface of the paddle card 2 on the +Z-axis side.

[0050] Here, as described above, the first partition member 12 and the second partition member 13 arranged on the +Z-axis side of the metal plate 11 and the first partition member 12 and the second partition member 13 arranged on the -Z-axis side of the metal plate 11 are in a point-symmetric relationship.

[0051] Therefore, as shown in Figure 4, when viewed from the X-axis direction, the first partitioning member 12 arranged on the +Z-axis side of the metal plate 11 and the first partitioning member 12 arranged on the -Z-axis side of the metal plate 11 are arranged alternately in the Y-axis direction.

[0052] 11 is a perspective view of a representative second partition member in the connector assembly of this embodiment, viewed from the +Z-axis side. As shown in FIG. 11, the second partition member 13 has a partition wall 13a and a flat portion 13b. The partition wall 13a has substantially the same shape as the first partition wall 12a of the first partition member 12.

[0053] 11, the flat portion 13b is an end portion on the negative Z-axis side of the partition wall 13a, and protrudes from the end portion on the negative X-axis side toward the negative Y-axis side. The flat portion 13b is a plate body that is approximately parallel to the XY plane, and may be, for example, approximately rectangular when viewed from the Z-axis direction.

[0054] With the partition wall 13a of the second partition member 13 protruding from the flat portion 13b toward the +Z-axis side, as shown in Figures 7 and 8, the partition wall 13a of the second partition member 13 on the +Z-axis side of the metal plate 11 is positioned on the -Y-axis side at a predetermined pitch from the second partition wall 12b of the first partition member 12 on the -Y-axis side.

[0055] 7, flat portion 13b of second partition member 13 is electrically connected to and fixed to the surface on the +Z-axis side of metal plate 11. At this time, partition wall 13a of second partition member 13 protrudes from metal plate 11 on the +X-axis side as shown in FIG. 7, and the end of partition wall 13a on the +X-axis side is electrically connected to ground contact 2b provided on the surface on the +Z-axis side of paddle card 2.

[0056] As a result, as shown in Figures 3 and 5, on the Z-axis + side of the metal plate 11, the first partition wall 12a, the second partition wall 12b, and the partition wall 13a of the second partition member 13 are arranged at a predetermined pitch in the Y-axis direction.

[0057] As shown in Figure 6, on the negative Z-axis side of the metal plate 11, the first partition wall 12a, the second partition wall 12b, and the partition wall 13a of the second partition member 13 are arranged at a predetermined pitch in the Y-axis direction.

[0058] The cables 4 are arranged on the +Z-axis side and the -Z-axis side of the metal plate 11. Here, the cable 4 arranged on the +Z-axis side of the metal plate 11 and the cable 4 arranged on the -Z-axis side of the metal plate 11 are in a point-symmetric relationship with respect to an axis that passes through the center of the connector assembly 1 in the Y-axis direction and is parallel to the X-axis, and therefore the shape and arrangement of the cable 4 arranged on the +Z-axis side of the metal plate 11 will be described as a representative example.

[0059] The cable 4 is, for example, a twin-ax cable, and includes a first inner conductor 4a, a second inner conductor 4b, a dielectric 4c, a ground shield 4d, and an insulating coating 4e, as shown in FIG.

[0060] The first inner conductor 4a and the second inner conductor 4b may, for example, form a differential signal pair line. The dielectric 4c covers the first inner conductor 4a and the second inner conductor 4b, as shown in Fig. 4. In this case, the first inner conductor 4a and the second inner conductor 4b may protrude from the dielectric 4c toward the +X-axis side by approximately the same length.

[0061] The ground shield 4d covers the dielectric 4c. The insulating coating 4e covers the ground shield 4d. In this case, for example, as shown in FIG. 5, the end of the insulating coating 4e on the +X-axis side is stripped away, exposing the ground shield 4d from the insulating coating 4e. Note that in the illustrated example such as FIG. 5, the entire periphery of the end of the insulating coating 4e on the +X-axis side is stripped away to expose the ground shield 4d. However, a portion of the insulating coating 4e may be stripped away (or peeled away) to expose, for example, a portion of the ground shield 4d on the +Z-axis side or the -Z-axis side. In short, it is preferable that any portion of the insulating coating 4e on the +X-axis side is stripped away relative to the -X-axis side ends of the first partition wall 12a and the second partition wall 12b of the first partition member 12 of the cable 4.

[0062] As shown in Figure 5, the cable 4 is arranged on the Z-axis + side of the metal plate 11 between the first partition wall 12a and the second partition wall 12b of the first partition member 12, and between the second partition wall 12b of the first partition member 12 and the partition wall 13a of the second partition member 13.

[0063] The end of the first inner conductor 4a of the cable 4 on the +X-axis side and the end of the second inner conductor 4b on the +X-axis side are electrically connected to a signal contact 2a provided on the surface of the paddle card 2 on the +Z-axis side, as shown in Figures 3 and 5.

[0064] Fig. 12 is a perspective view of the periphery of a first partition member in the connector assembly of the present embodiment, as viewed from the +Z-axis side. Fig. 13 is an enlarged plan view of the periphery of the first partition member in the connector assembly of the present embodiment, as viewed from the +Z-axis side.

[0065] For example, as described above, the first partition wall 12a and the second partition wall 12b of the first partition member 12 and the partition wall 13a of the second partition member 13 are arranged at a predetermined pitch in the Y-axis direction. Therefore, as shown in Figures 12 and 13, the position of the cable 4 in the Y-axis direction is determined by the first partition wall 12a and the second partition wall 12b of the first partition member 12, or the second partition wall 12b of the first partition member 12 and the partition wall 13a of the second partition member 13.

[0066] This allows the cable 4 to be easily positioned, and the end of the first inner conductor 4a of the cable 4 on the +X-axis side and the end of the second inner conductor 4b on the +X-axis side can be easily electrically connected to the signal contacts 2a of the paddle card 2.

[0067] 5, the first partition wall 12a and the second partition wall 12b of the first partition member 12 and the partition wall 13a of the second partition member 13 cover the cable 4 from a position on the negative X-axis side of the portion where the ground shield 4d is exposed from the insulating coating 4e to a position beyond the positive X-axis end of the first inner conductor 4a and the positive X-axis end of the second inner conductor 4b of the cable 4. In other words, the first partition wall 12a and the second partition wall 12b of the first partition member 12 and the partition wall 13a of the second partition member 13 are longer in the X-axis direction than at least the portion of the first inner conductor 4a or the second inner conductor 4b of the cable 4 that is exposed from the dielectric 4c. This makes it possible to suppress crosstalk between the cables 4 lined up in the Y-axis direction.

[0068] In addition, as shown in Figure 5, the ground shield 4d exposed from the insulating coating 4e of the cable 4 is arranged between the first partition wall 12a and the second partition wall 12b of the first partition member 12, or between the second partition wall 12b of the first partition member 12 and the partition wall 13a of the second partition member 13, when viewed from the Z-axis direction.

[0069] Here, the ground shields 4d exposed from the insulating coating 4e of the cables 4 are preferably arranged side by side in the Y-axis direction as shown in Fig. 5. In other words, the ground shields 4d exposed from the insulating coating 4e of each cable 4 are preferably arranged at approximately the same positions in the X-axis direction.

[0070] The ground shield 4d exposed from the insulating coating 4e of the cable 4 is electrically connected to the ground member 3 (for example, a partition wall that sandwiches the cable 4 in the Y-axis direction) by a conductive material (for example, solder 8) as shown in Fig. 5. Note that in Fig. 5 and other figures, the solder 8 is shown in a see-through manner so that the ground shield 4d exposed from the insulating coating 4e of the cable 4 can be clearly seen.

[0071] This forms a ground path that connects the ground shield 4d of the cable 4 to the ground contact 2b of the paddle card 2 via the ground member 3. In this case, the ground shields 4d exposed from the insulating coating 4e of the cables 4 aligned in the Y-axis direction are preferably electrically connected by solder 8, as shown in FIG.

[0072] By electrically connecting the ground shields 4d exposed from the insulating coatings 4e of the cables 4 aligned in the Y-axis direction in this way, the ground reference can be maintained, stabilizing the insertion loss and, as a result, improving the transmission characteristics.

[0073] The locator 5 aligns the cables 4 that are lined up in the Y-axis direction. As shown in Fig. 2, the locator 5 is, for example, a substantially rectangular cylinder that is long in the Y-axis direction when viewed from the Z-axis direction, and has a width in the X-axis direction. Furthermore, on the inner periphery of the locator 5, as shown in Fig. 5, positioning grooves 5a for the cables 4 are lined up in the Y-axis direction.

[0074] As shown in Fig. 5, the cables 4 are passed through the locator 5 in the X-axis direction. As a result, each cable 4 is aligned in the Y-axis direction following the positioning grooves 5a. At this time, as shown in Fig. 2, openings 5b are formed in the locator 5 on the inner side of the connector assembly 1 in the Z-axis direction, and each cable 4 and the locator 5 are preferably fixed by applying an adhesive to the openings 5b.

[0075] 1, the housing 6 includes a first case 6a and a second case 6b. The first case 6a and the second case 6b are stacked and fixed in the Z-axis direction so as to sandwich the end portion on the Y-axis + side and the end portion on the Y-axis − side of the metal plate 11 from the Z-axis direction and to cover the connection portion between the paddle card 2 and the cable 4, the ground member 3, and the locator 5.

[0076] 1, the paddle card 2 protrudes from the housing 6 toward the +X-axis side, and the cable 4 protrudes from the housing 6 toward the -X-axis side. The housing 6 may be, for example, as shown in FIG. 1, a rectangular box that is long in the Y-axis direction when viewed from the X-axis direction and is also long in the Y-axis direction when viewed from the Z-axis direction.

[0077] 1, a fitted portion 6c into which the frame 7 is fitted may be formed on the positive X-axis side of the housing 6. The fitted portion 6c may be formed, for example, by cutting out the peripheral edge of the positive X-axis side of the housing 6. However, the housing 6 may have a shape that can cover at least the connection portion between the paddle card 2 and the cable 4, the ground member 3, and the locator 5.

[0078] The frame 7 is fitted to the frame of the connector that is fitted to the connector assembly 1. As shown in Fig. 1, the frame 7 is, for example, a rectangular cylinder that is long in the Y-axis direction when viewed from the X-axis direction, and is fitted into and fixed to the fitted portion 6c of the housing 6. The frame 7 may be made of metal, for example.

[0079] The connector assembly 1 of this embodiment may also include a lever member for engaging with the connector to be mated with the connector assembly 1 and an operating member for operating the lever member, although these are omitted as they are not an essential part of the present disclosure.

[0080] Next, a manufacturing process for the connector assembly 1 of this embodiment will be described. First, the first partition member 12 and the second partition member 13 are fixed to the metal plate 11 to form the ground member 3. At this time, by fitting the connecting portion 12f of the fixing portion 12d of the first partition member 12 into the recess 11a of the metal plate 11, the first partition member 12 can be easily positioned relative to the metal plate 11.

[0081] Meanwhile, the cable 4 is passed through the locator 5 and fixed in place. Then, the dielectric 4c, ground shield 4d, and insulating coating 4e are stripped from the end of the cable 4 on the +X-axis side to expose the first inner conductor 4a and the second inner conductor 4b. The insulating coating 4e of the cable 4 is also stripped from the end on the +X-axis side to expose the ground shield 4d.

[0082] Next, in the X-axis direction, the end of the first partition wall 12a of the first partition member 12 in the ground member 3 on the X-axis + side, the end of the second partition wall 12b on the X-axis + side, and the end of the partition wall 13a of the second partition member 13 on the X-axis + side are positioned so as to overlap with the ground contact 2b of the paddle card 2.

[0083] Next, the cable 4 is placed between the first partition wall 12a and the second partition wall 12b of the first partition member 12 in the grounding member 3, and between the second partition wall 12b of the first partition member 12 and the partition wall 13a of the second partition member 13.

[0084] In this case, when viewed from the Z-axis direction, the cable 4 arranged between the first partition member 12 on the +Z-axis side of the metal plate 11, or between the first partition member 12 and the second partition member 13, is arranged so as to overlap with the flat portion 12e of the fixed portion 12d of the first partition member 12 arranged on the -Z-axis side of the metal plate 11.

[0085] Furthermore, when viewed from the Z-axis direction, the cable 4 arranged between the first partition members 12 on the negative side of the Z-axis relative to the metal plate 11, or between the first partition member 12 and the second partition member 13, is arranged so as to overlap with the flat portion 12e of the fixed portion 12d of the first partition member 12 arranged on the positive side of the Z-axis relative to the metal plate 11.

[0086] Next, in the Z-axis direction, the end of the first inner conductor 4a of the cable 4 on the +X-axis side and the end of the second inner conductor 4b on the +X-axis side are arranged to overlap with the signal contact 2a of the paddle card 2.

[0087] Next, the ground shield 4d exposed from the insulating coating 4e of the cable 4 is electrically connected to the ground member 3 with solder 8, and the ground shields 4d of the cables 4 aligned in the Y-axis direction are electrically connected to each other.

[0088] In this case, if the ground shields 4d exposed from the insulating coating 4e of the cables 4 are aligned in the Y-axis direction, the ground shields 4d of the cables 4 aligned in the Y-axis direction can be easily connected to each other.

[0089] Next, the end of the first inner conductor 4a of the cable 4 on the +X axis side and the end of the second inner conductor 4b on the +X axis side are electrically connected to the signal contacts 2a of the paddle card 2. At this time, since the signal contacts 2a of the paddle card 2 are aligned in the Y axis direction, the cable 4 can be easily connected to the paddle card 2.

[0090] Then, the end portion of the first partition wall 12a of the first partition member 12 on the +X-axis side, the end portion of the second partition wall 12b on the +X-axis side, and the end portion of the partition wall 13a of the second partition member 13 on the +X-axis side of the first partition wall 12a of the ground member 3 are electrically connected to the ground contacts 2b of the paddle card 2. At this time, since the ground contacts 2b of the paddle card 2 are aligned in the Y-axis direction, the ground member 3 can be easily connected to the paddle card 2.

[0091] Next, the housing 6 sandwiches the Y-axis positive end and the Y-axis negative end of the metal plate 11 in the Z-axis direction, covering the connection portion between the paddle card 2 and the cable 4, the ground member 3, and the locator 5. Then, the frame 7 is fitted into the mating portion 6c of the housing 6, thereby completing the manufacture of the connector assembly 1.

[0092] In the connector assembly 1 of this embodiment, first partition members 12, each having a basic shape of a substantially U-shape when viewed in the X-axis direction, are fixed to a metal plate 11 at a pitch twice the predetermined pitch to form a ground member 3, and first partition walls 12a and second partition walls 12b of the first partition member 12 are aligned in the Y-axis direction. Furthermore, the ground shield 4d exposed from the insulating coating 4e of the cable 4 is electrically connected to the first partition member 12 while being positioned between the first partition wall 12a and the second partition wall 12b of the first partition member 12. Therefore, in the connector assembly 1 of this embodiment, the ground connections can be positioned substantially linearly in the Y-axis direction, enabling the connector assembly 1 to be made smaller than the connector assembly of Patent Document 1.

[0093] In the connector assembly 1 of this embodiment, the first partition member 12 of the grounding member 3 is electrically connected to the ground contacts 2b of the paddle card 2. Therefore, a ground path is formed that connects the ground shield 4d of the cable 4 to the ground contacts 2b of the paddle card 2 via the grounding member 3.

[0094] As a result, the connector assembly 1 of this embodiment can be made smaller than the connector assembly of Patent Document 1 while still forming a ground path between the cable 4 and the paddle card 2.

[0095] In the connector assembly 1 of this embodiment, the ground member 3 includes the metal plate 11, and therefore the thickness of the metal plate 11 can be changed appropriately depending on the thickness of the paddle card 2.

[0096] In the connector assembly 1 of this embodiment, when viewed from the X-axis direction, the first partitioning members 12 arranged on the +Z-axis side of the metal plate 11 and the first partitioning members 12 arranged on the -Z-axis side of the metal plate 11 are arranged alternately in the Y-axis direction, so that the first partitioning members 12 adjacent in the Y-axis direction can be arranged close to each other. This allows the connector assembly 1 to be further miniaturized.

[0097] In the connector assembly 1 of this embodiment, the first partition wall 12a and the second partition wall 12b of the first partition member 12 cover the portion of the cable 4 where the ground shield 4d is exposed from the insulating coating 4e from a position on the negative X-axis side to a position beyond the positive X-axis end of the first inner conductor 4a and the positive X-axis end of the second inner conductor 4b of the cable 4. This makes it possible to suppress crosstalk between the cables 4 arranged in the Y-axis direction. In other words, this leads to suppression of crosstalk between channels and improved transmission performance.

[0098] In the connector assembly 1 of this embodiment, when the ground shields 4d exposed from the insulating coating 4e of the cables 4 aligned in the Y-axis direction are electrically connected to each other, the ground reference can be maintained, thereby stabilizing the insertion loss and resulting in improved transmission characteristics. In addition, when the ground shields 4d exposed from the insulating coating 4e of the cables 4 are aligned in the Y-axis direction, the ground shields 4d of the cables 4 aligned in the Y-axis direction can be easily connected to each other.

[0099] In the connector assembly 1 of this embodiment, when the first partition member 12 has a fixing portion 12d, the first partition member 12 can be easily positioned relative to the metal plate 11 by fitting the connecting portion 12f of the fixing portion 12d in the first partition member 12 into the recess 11a of the metal plate 11.

[0100] Although the connector assembly 1 of this embodiment includes the second partition member 13, it may be omitted as appropriate depending on the number of cables 4.

[0101] <Embodiment 2> Fig. 14 is a perspective view of the connector assembly of the present embodiment as seen from the +Z axis side. Fig. 15 is a perspective view of the connector assembly of the present embodiment as seen from the +Z axis side, with the housing and frame omitted.

[0102] 14 and 15, connector assembly 21 of the present embodiment has substantially the same configuration as connector assembly 1 of embodiment 1, but differs in the configuration of ground member 22. Therefore, redundant explanations will be omitted and the configuration of ground member 22 will be mainly explained.

[0103] Fig. 16 is a perspective view of the paddle card and grounding member in the connector assembly of the present embodiment, as viewed from the +Z axis side. Fig. 17 is an exploded perspective view of the paddle card and grounding member in the connector assembly of the present embodiment, as viewed from the +Z axis side.

[0104] 16 and 17, the grounding member 22 includes a metal member 23, a first partition member 24, and a second partition member 25. The metal member 23 is a machined or molded metal product (e.g., a metal injection molded product). The metal member 23 includes, for example, a flat portion 23a, a first side wall portion 23b, and a second side wall portion 23c.

[0105] 16 and 17, the flat portion 23a is a plate that is approximately parallel to the XY plane and may have, for example, a substantially rectangular shape that is long in the Y-axis direction when viewed from the Z-axis direction. Recesses 23d are formed at a predetermined pitch at the end of the flat portion 23a on the negative X-axis side. In this embodiment, for example, an even number of recesses 23d are arranged in the Y-axis direction according to the number of cables 4 aligned in the Y-axis direction.

[0106] 16 and 17, first side wall portion 23b is fixed to the end portion of flat portion 23a on the +Y-axis side. First side wall portion 23b is a plate member substantially parallel to the XZ plane, and may have, for example, a substantially rectangular shape that is long in the X-axis direction when viewed from the Y-axis direction. A notch 23e is formed in a portion of first side wall portion 23b that protrudes from flat portion 23a toward the +X-axis side.

[0107] 16 and 17, cutout portion 23e has a shape that allows the negative end of paddle card 2 on the X-axis to be inserted. Cutout portion 23e has, for example, a substantially rectangular shape when viewed from the Y-axis direction, and extends in the X-axis direction to reach the positive end of first side wall portion 23b on the X-axis. The height of cutout portion 23e in the Z-axis direction is substantially equal to the thickness of paddle card 2 in the Z-axis direction.

[0108] 16 and 17, the second side wall portion 23c is fixed to the end portion on the Y-axis negative side of the flat portion 23a. The second side wall portion 23c has substantially the same shape as the first side wall portion 23b when viewed from the Y-axis direction, and is formed with a notch portion 23f.

[0109] 16 and 17, the first partitioning member 24 and the second partitioning member 25 are disposed on the +Z-axis side and the -Z-axis side, respectively, of the flat portion 23a of the metal member 23. Here, the first partitioning member 24 and the second partitioning member 25 disposed on the +Z-axis side of the flat portion 23a of the metal member 23 and the first partitioning member 24 and the second partitioning member 25 disposed on the -Z-axis side of the flat portion 23a of the metal member 23 are in a point-symmetric relationship with respect to an axis that passes through the center of the connector assembly 21 in the Y-axis direction and is parallel to the X-axis. Therefore, the shape and arrangement of the first partitioning member 24 and the second partitioning member 25 disposed on the +Z-axis side of the flat portion 23a of the metal member 23 will be described as a representative example.

[0110] Figure 18 is a perspective view of a typical first partition member of a grounding member in a connector assembly according to the present embodiment, as viewed from the +Z-axis side. Figure 19 is a different perspective view of a typical first partition member of a grounding member in a connector assembly according to the present embodiment, as viewed from the +Z-axis side.

[0111] 18 and 19, the first partition member 24 includes a first partition wall 24a, a second partition wall 24b, a flat portion 24c, an extension portion 24d, and a press-fit portion 24e. The first partition wall 24a, the second partition wall 24b, and the flat portion 24c have substantially the same shapes as the first partition wall 12a, the second partition wall 12b, and the flat portion 12c of the first partition member 12 of the first embodiment.

[0112] 18 and 19, extension portion 24d protrudes toward the negative X-axis side from flat portion 24c. Extension portion 24d is a plate member substantially parallel to the XY plane, and may have, for example, a substantially rectangular shape that is long in the X-axis direction when viewed from the Z-axis direction. Press-fit portion 24e protrudes toward the negative Z-axis side from the end of flat portion 24c on the negative Y-axis side.

[0113] 18 and 19, the press-fit portion 24e is a plate that is approximately parallel to the XZ plane and may have, for example, a substantially rectangular shape that is long in the X-axis direction when viewed in the Y-axis direction. The thickness of the press-fit portion 24e in the Y-axis direction may be approximately equal to the width dimension in the Y-axis direction of the recess 23d in the flat portion 23a of the metal member 23. The press-fit portion 24e is disposed approximately in the center of the first partition member 24 in the Y-axis direction.

[0114] Then, with the first partition wall 24a and the second partition wall 24b of the first partition member 24 protruding from the flat portion 24c toward the Z-axis + side, as shown in Figures 16 and 17, the press-fit portion 24e from the X-axis - side is press-fit into the even-numbered recesses 23d from the Y-axis + side among the recesses 23d of the metal member 23, except for the recess 23d on the Y-axis - side.

[0115] As a result, as shown in Figure 16, the first partitioning member 24 is fixed to the metal member 23 with the first partitioning wall 24a, second partitioning wall 24b, and flat portion 24c of the first partitioning member 24 positioned on the +Z axis side of the flat portion 23a of the metal member 23.

[0116] At this time, as shown in Figure 16, the first partition members 24 are arranged at a pitch twice the predetermined pitch in the Y-axis direction, and the first partition walls 24a and the second partition walls 24b are repeatedly arranged at a predetermined pitch in the Y-axis direction.

[0117] Here, as described above, the first partitioning member 24 arranged on the +Z-axis side of the flat portion 23a of the metal member 23 and the first partitioning member 24 arranged on the -Z-axis side of the flat portion 23a of the metal member 23 are in a point-symmetric relationship.

[0118] Therefore, as shown in Figure 17, when viewed from the X-axis direction, the first partitioning member 24 arranged on the +Z-axis side of the flat portion 23a of the metal member 23 and the first partitioning member 24 arranged on the -Z-axis side of the flat portion 23a of the metal member 23 are arranged alternately in the Y-axis direction.

[0119] Figure 20 is a perspective view of a representative second partitioning member in the connector assembly of this embodiment, as viewed from the +Z-axis side. As shown in Figure 20, second partitioning member 25 includes partitioning wall 25a, flat portion 25b, extension portion 25c, and press-fit portion 25d. Partitioning wall 25a and flat portion 25b have substantially the same shapes as partitioning wall 13a and flat portion 13b of second partitioning member 13 of embodiment 1.

[0120] 20, the extension portion 25c and the press-fit portion 25d have substantially the same shapes as the extension portion 24d and the press-fit portion 24e of the first partition member 24, and protrude from the flat portion 23a toward the negative side of the X axis. The press-fit portion 25d is disposed substantially in the center of the second partition member 25 in the Y axis direction.

[0121] Then, with the partition wall 25a of the second partition member 25 protruding from the flat portion 25b toward the Z-axis + side, the press-fit portion 25d is press-fitted into the recess 23d on the Y-axis - side of the metal member 23 from the X-axis - side, as shown in Figures 16 and 17.

[0122] As a result, as shown in Figure 16, the first partition wall 24a, the second partition wall 24b, and the partition wall 25a of the second partition member 25 of the first partition member 24 are arranged at a predetermined pitch in the Y-axis direction on the Z-axis + side of the flat portion 23a of the metal member 23.

[0123] Also, as shown in Figure 16, on the Z-axis -side of the flat portion 23a of the metal member 23, the first partition wall 24a, the second partition wall 24b of the first partition member 24, and the partition wall 25a of the second partition member 25 are arranged at a predetermined pitch in the Y-axis direction.

[0124] As shown in Figure 17, it is preferable that a protrusion 24f protruding in the Y-axis direction is formed in the press-fit portion 24e of the first partition member 24, and a protrusion 25e protruding in the Y-axis direction is formed in the press-fit portion 25d of the second partition member 25.

[0125] This allows the first partition member 24 and the second partition member 25 to be firmly fixed to the metal member 23 when the press-fit portion 24e of the first partition member 24 and the press-fit portion 25d of the second partition member 25 are press-fitted into the recess 23d of the flat portion 23a of the metal member 23.

[0126] As shown in Figures 15 and 16, such a grounding member 22 is fixed to the paddle card 2 with the paddle card 2 inserted into the cutout portion 23e of the first side wall portion 23b and the cutout portion 23f of the second side wall portion 23c of the metal member 23.

[0127] 15, the first side wall portion 23b and the second side wall portion 23c of the metal member 23 are electrically connected to the ground contact 2b of the paddle card 2. The first partition wall 24a and the second partition wall 24b of the first partition member 24 and the partition wall 25a of the second partition member 25 are also electrically connected to the ground contact 2b of the paddle card 2.

[0128] Furthermore, as shown in Figure 15, the first inner conductor 4a and the second inner conductor 4b of the cable 4 arranged between the first partition wall 24a and the second partition wall 24b of the first partition member 24 in the ground member 22, and between the second partition wall 24b of the first partition member 24 and the partition wall 25a of the second partition member 25, are electrically connected to the signal contact 2a of the paddle card 2.

[0129] 15 , the first partition wall 24a and the second partition wall 24b of the first partition member 24 and the partition wall 25a of the second partition member 25 cover, as viewed from the Y-axis direction, from a position on the negative X-axis side of the portion of the cable 4 where the ground shield 4d is exposed from the insulating coating 4e to a position beyond the positive X-axis end of the first inner conductor 4a and the positive X-axis end of the second inner conductor 4b of the cable 4. In other words, the first partition wall 24a and the second partition wall 24b of the first partition member 24 and the partition wall 25a of the second partition member 25 are longer in the X-axis direction than at least the portion of the first inner conductor 4a or the second inner conductor 4b of the cable 4 that is exposed from the dielectric 4c.

[0130] As described above, connector assembly 21 of the present embodiment differs from connector assembly 1 of embodiment 1 in the configuration of grounding member 22. Therefore, housing 26 may be configured to cover metal member 23 of grounding member 22, as shown in Fig. 14 , compared to housing 6 of connector assembly 1 of embodiment 1.

[0131] In connector assembly 21 of the present embodiment, first partition members 24, each having a basic shape substantially U-shaped when viewed in the X-axis direction, are fixed to metal member 23 at a pitch twice the predetermined pitch to form ground member 22, and first partition walls 24a and second partition walls 24b of first partition member 24 are aligned in the Y-axis direction. Furthermore, ground shield 4d exposed from insulating coating 4e of cable 4 is electrically connected to first partition member 24 while being positioned between first partition wall 24a and second partition wall 24b of first partition member 24. Therefore, in connector assembly 21 of the present embodiment, the ground connections can also be aligned substantially linearly in the Y-axis direction, enabling connector assembly 21 to be made smaller than the connector assembly of Patent Document 1.

[0132] In connector assembly 21 of this embodiment, ground member 22 is electrically connected to ground contact 2b of paddle card 2. Therefore, a ground path is formed that connects ground shield 4d of cable 4 to ground contact 2b of paddle card 2 via ground member 22.

[0133] As a result, connector assembly 21 of this embodiment can also be made smaller than the connector assembly of Patent Document 1 while forming a ground path between cable 4 and paddle card 2.

[0134] <Third Embodiment> Fig. 21 is a perspective view of the paddle card and grounding member in the connector assembly of the present embodiment, as viewed from the +Z-axis side. Fig. 22 is an exploded perspective view of the paddle card and grounding member in the connector assembly of the present embodiment, as viewed from the +Z-axis side.

[0135] The ground member 22 of the connector assembly 21 of embodiment 2 uses a first partition member 24 and a second partition member 25, but as shown in Figures 21 and 22, a plate-shaped partition member 31 may be used instead of the first partition member 24 and the second partition member 25.

[0136] Fig. 23 is a perspective view of the partition member of the grounding member of this embodiment, viewed from the +Z-axis side. Fig. 24 is a different perspective view of the partition member of the grounding member of this embodiment, viewed from the +Z-axis side. As shown in Figs. 23 and 24, the partition member 31 is a plate that is approximately parallel to the XZ plane.

[0137] The thickness of the partitioning member 31 in the Y-axis direction is preferably approximately equal to the width in the Y-axis direction of the recessed portion 23d of the flat portion 23a of the metal member 23. The partitioning member 31 is preferably approximately U-shaped when viewed in the Y-axis direction, as shown in Figures 23 and 24. That is, the partitioning member 31 includes a partition wall 31a and a cutout portion 31b.

[0138] 23 and 24, the cutout portion 31b is the negative X-axis side portion of a substantially rectangular two-stage recess that is long in the X-axis direction. The height of the cutout portion 31b in the Z-axis direction is substantially equal to the thickness of the flat portion 23a of the metal member 23 in the Z-axis direction.

[0139] 21, with the flat portion 23a of the metal member 23 inserted through the cutout portion 31b of the partitioning member 31 from the negative X-axis side, the portion on the negative X-axis side of the cutout portion 31b of the partitioning member 31 is press-fitted into the recess 23d of the flat portion 23a. In other words, the portion on the negative X-axis side of the cutout portion 31b of the partitioning member 31 functions as a press-fit portion.

[0140] 21, the end of partitioning member 31 on the +X-axis side protrudes from flat portion 23a of metal member 23 to the +X-axis side. The +Z-axis side and -Z-axis side portions of flat portion 23a of metal member 23, with cutout portion 31b in partitioning member 31 in between, form partition walls 31a, and are arranged at a predetermined pitch in the Y-axis direction, similar to first partition wall 24a, second partition wall 24b, and partition wall 25a of second partitioning member 25 of the second embodiment.

[0141] The cable 4 is disposed between the partition walls 31a of the partition member 31, and the first inner conductor 4a and the second inner conductor 4b of the cable 4 are electrically connected to the signal contacts 2a of the paddle card 2. In this case, when viewed from the Y-axis direction, the partition walls 31a of the partition member 31 cover the cable 4 from a position on the negative X-axis side of the portion where the ground shield 4d is exposed from the insulating coating 4e to a position beyond the positive X-axis end of the first inner conductor 4a and the positive X-axis end of the second inner conductor 4b of the cable 4.
