[0009] [Description of Embodiments in this Disclosure] First, embodiments of the present disclosure will be listed and described.

[0010] The connector device of the present disclosure is as follows.

[0011] (1) A first connector connected to a first substrate and a second connector connected to a second substrate, the first connector and the second connector being fitted along a first direction, the first connector including a first signal terminal and a first connector housing that holds the first signal terminal, the second connector including a second signal terminal connected to the first signal terminal and a second connector housing that holds the second signal terminal, the contact portion between the first signal terminal and the second signal terminal having a first spring contact portion and a second spring contact portion that are separated from each other along the first direction, the first signal terminal having a first extending portion that extends between the first spring contact portion and the second spring contact portion, the second signal terminal having a second extending portion that extends between the first spring contact portion and the second spring contact portion, in the first direction, the first connector and the second connector taking any one of a first fitting dimension and a second fitting dimension larger than the first fitting dimension, in the first direction, the distance between the first spring contact portion and the second spring contact portion taking any one of a first distance when the first fitting dimension is taken and a second distance that is larger than the first distance and is the distance when the second fitting dimension is taken, the first extending portion and the second extending portion being separated from each other along a second direction orthogonal to the first direction when the first fitting dimension is taken, the first connector housing having a housing pressing portion that presses the second connector housing when the fitting dimension between the first connector and the second connector is larger than the first fitting dimension, and the second connector housing having a pressed portion that is pressed by the housing pressing portion and a terminal pressing portion that presses the second signal terminal to bring the second extending portion closer to the first extending portion when the pressed portion is pressed by the housing pressing portion, which is a connector device.

[0012] (1) According to the connector device, due to differences in the distance between substrates, etc., the distance between the two spring contact portions can change, and the impedance can change. This can occur due to a change in the size of the space between the two spring contact portions. In the present disclosure, when the two spring contact portions move apart, it is possible to suppress a change in the size of the space between the two spring contact portions by the portion between the two spring contact portions approaching. Thereby, it is possible to suppress a change in impedance due to the tolerance of the distance between substrates.

[0013] (2) In the connector device of (1), a direction orthogonal to the first direction and the second direction is defined as the third direction. The second connector housing includes a fixed housing fixed to the second substrate and a movable housing movable along the second direction and the third direction with respect to the fixed housing. The first end portion of the second signal terminal is held by the fixed housing, the second end portion of the second signal terminal is held by the movable housing, the second extending portion is provided at the second end portion, the pressed portion and the terminal pressing portion are provided on the movable housing, and the movable housing may move with respect to the fixed housing when the pressed portion is pressed by the housing pressing portion. Thereby, by moving the movable housing with respect to the fixed housing, impedance matching due to the tolerance of the distance between substrates can be achieved.

[0014] (3) In the connector device of (2), the movable housing has a first movable housing and a second movable housing arranged along the second direction. The pressed portion is provided at the tip of the first movable housing and the tip of the second movable housing. When the pressed portion is pressed by the housing pressing portion, the tip of the first movable housing and the tip of the second movable housing may move away from each other in the second direction. Thereby, impedance matching can be achieved collectively for each signal terminal held by the two movable housings.

[0015] (4) In the connector device of (2) or (3), a correction unit is provided for correcting the misalignment of the first connector and the second connector in the second and third directions, and the correction unit may have a correction housing pressing unit provided on the first connector housing, a correction pressed unit provided on the movable housing, and a correction terminal pressing unit that causes the second end of the second signal terminal to follow the movement of the movable housing when the correction housing pressing unit presses the correction pressed unit. This makes it possible to achieve impedance matching due to the difference in distance between boards in a connector device having a floating structure that can absorb misalignment in a direction parallel to the board surface.

[0016] In the connector device of (5)(4), the corrective housing pressing portion may be provided so as to come into contact with the corrective pressed portion before the housing pressing portion comes into contact with the pressed portion along the first direction. This makes it possible to achieve impedance matching for the misalignment in the first direction after the correction of the misalignment in the second and third directions is completed.

[0017] (6) In any one connector device of (2) to (5), the first connector includes a first power terminal held in the first connector housing, the second connector includes a second power terminal held in the second connector housing, and the movable housing includes a movable housing for signal terminals that holds the second signal terminal and a movable housing for power terminals that holds the second power terminal separately from the second signal terminal, wherein the first end of the second power terminal is held in the fixed housing and the second end of the second power terminal is held in the movable housing for power terminals. This makes it easier to achieve impedance matching of signal terminals by separating the movable housing for signal terminals where impedance matching is desired from the movable housing for power terminals where impedance matching is not required.

[0018] [Details of the embodiments of this disclosure] Specific examples of the connector devices of this disclosure will be described below with reference to the drawings. However, this disclosure is not limited to these examples, and all modifications within the meaning and scope of the claims are intended to be included.

[0019] [Embodiment 1] The connector device according to Embodiment 1 will be described below.

[0020] <Connector device> The overall configuration of the connector device will be described with reference to Figures 1 to 4. Figure 1 is an exploded perspective view showing the connector device 100 according to Embodiment 1. Figure 2 is an exploded front view showing the connector device 100 shown in Figure 1. Figure 3 is an exploded side view showing the connector device 100 shown in Figure 1. Figure 4 is a cross-sectional view along the line IV-IV in Figure 2. In this disclosure, the three mutually orthogonal directions are denoted as the X direction, Y direction, and Z direction, respectively. One direction in the X direction is denoted as X1, and the opposite direction as X2. One direction in the Y direction is denoted as Y1, and the opposite direction as Y2. One direction in the Z direction is denoted as Z1, and the opposite direction as Z2. In each figure, X1, X2, Y1, Y2, Z1, and Z2 are shown.

[0021] The connector device 100 comprises a first connector 10 and a second connector 30 that mates with the first connector 10. As shown in Figure 2 and other figures, in this embodiment, the first connector 10 and the second connector 30 are described as board connectors that are electrically connected to the first substrate B1 and the second substrate B2, respectively. When the first connector 10 and the second connector 30 are mated, the terminals of the first connector 10 and the terminals of the second connector 30 are electrically connected. As a result, the substrates B1 and B2 to which the first connector 10 and the second connector 30 are connected are electrically connected. The first connector 10 and the second connector 30 may be connectors other than board connectors.

[0022] The first connector 10 and the second connector 30 are mated by moving toward each other along the mating direction. In this embodiment, the mating direction is perpendicular to the main surfaces of the substrates B1 and B2. Here, the Z direction is the mating direction. Hereafter, the Z direction may be referred to as the up and down direction. The X and Y directions are perpendicular to the mating direction and are along the main surfaces of the substrates B1 and B2. Note that the mating direction of the first connector 10 and the second connector 30 may be a direction other than the Z direction. In this embodiment, the first direction is the Z direction, the second direction is the Y direction, and the third direction is the X direction.

[0023] <First Connector> The first connector 10 will be described with further reference to Figures 5 and 6. Figure 5 is an exploded perspective view showing the first connector 10 shown in Figure 1. Figure 6 is a plan view showing the first connector 10 shown in Figure 1.

[0024] The first connector 10 includes a first connector housing 11, a plurality of first signal terminals 16, and a plurality of first power terminals 21. The first signal terminals 16 are terminals for signal transmission. The first power terminals 21 are terminals for power supply. The first connector 10 is fixed to the first circuit board B1 by a fixing device 28.

[0025] The first connector housing 11 is molded using an electrically insulating material such as synthetic resin. The first connector housing 11 has a signal terminal holding portion 12 for holding the first signal terminals 16 and a power terminal holding portion 13 for holding the first power terminals 21. The first connector housing 11 holds a plurality of first signal terminals 16 and a plurality of first power terminals 21 in a predetermined arrangement by the signal terminal holding portion 12 and the power terminal holding portion 13. Here, the plurality of first signal terminals 16 and the plurality of first power terminals 21 are arranged in two rows in the Y direction. The plurality of first signal terminals 16 are arranged in groups of three or more in the X direction. The plurality of first power terminals 21 are provided on each side in the X direction relative to the plurality of first signal terminals 16. Note that the arrangement of the plurality of first signal terminals 16 and the plurality of first power terminals 21 is not limited to the above and can be set as appropriate. The orientation of a pair of adjacent first signal terminals 16 along the X direction is the same. The orientations of a pair of adjacent first signal terminals 16 along the Y direction are opposite to each other. Similarly, the orientations of a pair of adjacent first power terminals 21 along the X direction are the same, while the orientations of a pair of adjacent first power terminals 21 along the Y direction are opposite to each other.

[0026] The signal terminal holding portion 12 has a portion in which a holding hole 12H is formed and a portion in which a holding groove 12G is formed. The holding hole 12H penetrates in the Z direction. The holding groove 12G is formed such that its bottom surface is located on the outside along the Y direction, and its side walls are located on both sides in the X direction relative to the bottom surface. The holding groove 12G is formed such that the inner wall portion along the Y direction of the inner circumferential wall portion of the holding hole 12H is omitted. As shown in Figure 4, in the state before mating, two signal terminals aligned in the Y direction face each other at the position of the holding groove 12G. The power terminal holding portion 13 holds the first power terminal 21 while partitioning it. The power terminal holding portion 13 has a plurality of holes corresponding to a plurality of first power terminals 21.

[0027] The first signal terminal 16 and the first power terminal 21 are each formed into a predetermined shape by press-forming (punching and bending) a flat plate of a conductive material such as metal. Such a flat plate is curved in the YZ plane and extends generally in the Z direction so that it is elongated in the Z direction. The cross-section of such a flat plate is, for example, rectangular. In the rectangular cross-section, the shorter direction is the plate thickness direction, and the longer direction is the plate width direction. The first signal terminal 16 and the first power terminal 21 are each positioned such that the plate width direction of the flat plate is aligned with the X direction. Furthermore, the thickness of the flat plate in the Y direction in the portion of the flat plate that extends parallel to the Z direction is the plate thickness. Therefore, in this embodiment, the Z direction is the extension direction of the plate material, the Y direction is the plate thickness direction of the plate material, and the X direction is the plate width direction of the plate material.

[0028] The first signal terminal 16 has a board connection portion 17 at one end, a first spring contact portion 18 at the other end, and a press-fit projection 19 provided between the board connection portion 17 and the first spring contact portion 18. The board connection portion 17 protrudes to the outside of the signal terminal holding portion 12. The board connection portion 17 is connected to the circuit of the first board B1. The press-fit projection 19 is press-fitted into the holding hole 12H of the signal terminal holding portion 12. This fixes the first signal terminal 16 to the first connector housing 11. The first spring contact portion 18 is located at the tip of the holding groove 12G. The tip of the holding groove 12G is deeper than the base of the holding groove 12G. This allows deformation of the first spring contact portion 18.

[0029] The first power terminal 21 has a board connection portion 22 at one end, a cylindrical portion 23 at the other end, and a press-fit projection 24 on the outer surface of the cylindrical portion 23. The board connection portion 22 protrudes to the outside of the power terminal holding portion 13. The board connection portion 22 is connected to the circuit of the first board B1. The press-fit projection 24 is press-fitted into the holding hole 13H of the power terminal holding portion 13. In this way, the first power terminal 21 is fixed to the first connector housing 11.

[0030] The first connector housing 11 includes a corrective housing pressing portion 14. The corrective housing pressing portion 14 corrects the misalignment of the first connector 10 and the second connector 30 in the X and Y directions. The corrective housing pressing portions 14 are provided at both ends of the first connector housing 11 along the X direction. Two power terminal holding portions 13 are located between the two corrective housing pressing portions 14, and one signal terminal holding portion 12 is located between the two power terminal holding portions 13. As shown in Figure 5, the tips of the corrective housing pressing portions 14 protrude towards the Z2 side more than the signal terminal holding portions 12 and the power terminal holding portions 13. As shown in Figure 2, the X-outward surfaces of the tips of the two corrective housing pressing portions 14 are inclined surfaces. As shown in Figure 3, the Y-outward surfaces of the tips of each corrective housing pressing portion 14 are inclined surfaces.

[0031] The first connector housing 11 includes a housing pressing portion 15. The housing pressing portion 15 performs impedance matching when there is a misalignment in the Z direction between the first connector 10 and the second connector 30. As shown in Figure 4, the housing pressing portion 15 is provided inside the signal terminal holding portion 12. A block portion is provided inside the signal terminal holding portion 12. The block portion has the inner circumferential wall portion of the holding hole 12H of the signal terminal holding portion 12 that is inward in the Y direction. The housing pressing portion 15 protrudes toward the Z2 side from the Z2 side facing surface of the block portion. The surface of the housing pressing portion 15 that faces outward in the Y direction is inclined, similar to the corrective housing pressing portion 14. The tip of the housing pressing portion 15 does not reach the first spring contact portion 18.

[0032] <Second connector> The second connector 30 will be described with further reference to Figures 7 and 8. Figure 7 is an exploded perspective view showing the second connector 30 shown in Figure 1. Figure 8 is a plan view showing the second connector 30 shown in Figure 1.

[0033] The second connector 30 comprises a second connector housing 31, a plurality of second signal terminals 52, and a plurality of second power terminals 60. The plurality of second signal terminals 52 and the plurality of second power terminals 60 are held in the second connector housing 31. The second signal terminals 52 are terminals for signal transmission and are connected to the first signal terminal 16. The second power terminals 60 are terminals for power supply and are connected to the first power terminal 21.

[0034] Here, the second connector housing 31 comprises a fixed housing 32 and a movable housing 40. The fixed housing 32 is fixed to the second substrate B2 via a fastener 70. The movable housing 40 is provided to be movable relative to the fixed housing 32.

[0035] Multiple second signal terminals 52 and multiple second power terminals 60 are bridged between the fixed housing 32 and the movable housing 40. In this embodiment, the movable housing 40 is supported in a floating state relative to the fixed housing 32 via the second signal terminals 52 and the second power terminals 60. As a result, the movable housing 40 is supported so as to be movable relative to the fixed housing 32. The movable housing 40 is movable relative to the fixed housing 32 along the X and Y directions.

[0036] In this embodiment, the movable housing 40 is movable relative to the fixed housing 32 in any direction within the plane, including the X and Y directions. That is, the movable housing 40 is movable relative to the fixed housing 32 not only in the X and Y directions, but also in directions that are inclined with respect to the X and Y directions within the XY plane. The movement vector indicating the direction and amount of movement of the movable housing 40 can also be considered as the sum of the movement vector in the X direction and the movement vector in the Y direction.

[0037] Multiple second signal terminals 52 and multiple second power terminals 60 are arranged in the same order as multiple first signal terminals 16 and multiple first power terminals 21. A pair of adjacent second signal terminals 52 along the X direction are oriented in the same direction. A pair of adjacent second signal terminals 52 along the Y direction are oriented in opposite directions. Similarly, a pair of adjacent second power terminals 60 along the X direction are oriented in the same direction, while a pair of adjacent second power terminals 60 along the Y direction are oriented in opposite directions.

[0038] The fixed housing 32 is molded using an electrically insulating material such as synthetic resin. The fixed housing 32 includes a peripheral wall 33 and a bottom block portion 34 that closes the Z2 side opening of the peripheral wall 33. Multiple through holes are formed in the bottom block portion 34. Thus, the fixed housing 32 is formed in a cylindrical shape with the upper part of the peripheral wall 33 open and the lower part of the peripheral wall 33 having multiple through holes, each smaller than the upper opening. The lower part of the movable housing 40 is positioned in the internal space of the peripheral wall 33, above the bottom block portion 34. The upper part of the movable housing 40 protrudes upward from the upper opening of the fixed housing 32. In the X and Y directions, the inner surface of the peripheral wall 33 and the outer surface of the movable housing 40 face each other with a gap between them. This gap is, for example, the same as the amount of movement of the movable housing 40 in the X and Y directions.

[0039] The fixed housing 32 includes a signal terminal holding portion 35, a power terminal holding portion 48, and a fixing device holding portion 38. Here, the signal terminal holding portion 35 and the power terminal holding portion 48 are provided on the bottom block portion 34, and the fixing device holding portion 38 is provided on the outer surface of the X-direction end of the peripheral wall 33.

[0040] The signal terminal holding portion 35 is the part that holds the first end of the second signal terminal 52. The signal terminal holding portion 35 is the part of the bottom block portion 34 located in the middle of the X direction, in which a holding hole 35H as a through hole is formed. Two holding holes 35H are provided in the Y direction. Each of the two holding holes 35H has a plurality of first holes and one second hole. In each holding hole 35H, the plurality of first holes are aligned in the X direction. The plurality of second signal terminals 52 aligned in the X direction are passed through the plurality of first holes individually. One second hole is located below the plurality of first holes. The plurality of first holes and the one second hole are continuous along the Z direction. The plurality of second signal terminals 52 aligned in the X direction are passed through the one second hole together.

[0041] The power terminal holding portion 48 is the part that holds the first end of the second power terminal 60. The power terminal holding portion 48 is the part of the bottom block portion 34 that is located outside the signal terminal holding portion 35 in the X direction and has a holding hole 36H formed as a through hole. A pair of power terminal holding portions 48 are provided, spaced apart from each other in the X direction. The signal terminal holding portion 35 is located between the pair of power terminal holding portions 48. The same number of holding holes 36H as there are second power terminals 60 are provided. Each holding hole 36H is individually fitted into a second power terminal 60.

[0042] Here, the portion of the bottom block 34 located outward in the X direction from the pair of power terminal holding portions 48 is designated as the housing support portion 37 that supports the lower end of the movable housing 40. The housing support portion 37 is surrounded by three wall portions at the X-direction end of the peripheral wall 33.

[0043] The fastener holding portion 38 is the part that holds the fastener 70. The fastener holding portion 38 is formed in the shape of a slot into which the fastener 70 can be inserted from the Z1 side.

[0044] In this configuration, the movable housing 40 is composed of three housings: a pair of movable housings 41 for signal terminals and a movable housing 45 for power terminals. Each of the three housings is molded as a separate component using an electrically insulating material such as synthetic resin.

[0045] The movable housing 41 for the signal terminal has a signal terminal holding portion 42, a retaining projection 43, and a recess 44. Here, the pair of movable housings 41 for the signal terminal are formed to be the same shape as each other and are arranged in opposite directions when viewed from the Z direction.

[0046] The signal terminal holding portion 42 is the part that holds the second end of the second signal terminal 52. The signal terminal holding portion 42 has a portion in which a holding hole 42H is formed and a portion in which a holding groove 42G is formed. The holding hole 42H and the holding groove 42G are continuous in the Z direction. The holding hole 42H penetrates the movable housing 41 for signal terminals in the Z direction. The holding groove 42G is formed such that its bottom surface 42GA is located on the inside along the Y direction, and side walls are located on both sides in the X direction relative to the bottom surface 42GA. The bottom surface 42GA of the holding groove 42G faces in the Y direction. The holding groove 42G is formed such that the outer wall portion along the Y direction of the inner circumferential wall portion of the holding hole 42H is omitted. The pair of movable housings 41 for signal terminals are arranged such that the bottom surface 42GA of the holding groove 42G of each movable housing 41 for signal terminals is located between the pair of second signal terminals 52 that are aligned in the Y direction. The tip of the retaining groove 42G is formed to be deep, similar to the tip of the retaining groove 12G, so that the second spring contact portion 55 can be released when the first spring contact portion 18 and the second spring contact portion 55 move over each other.

[0047] The retaining projections 43 are provided on both sides of the signal terminal holding portion 42 along the X direction. The retaining projections 43 protrude in the X direction from the outer surface of the signal terminal holding portion 42 in the middle of the Z direction.

[0048] The recess 44 is provided on the outer surface of the signal terminal holding portion 42 on the inner side in the Y direction. As shown in Figure 4, when the pair of movable housings 41 for signal terminals are lined up, the recess 44 is surrounded on all four sides by the signal terminal holding portion 42. As a result, the recess 44 of the pair of movable housings 41 for signal terminals forms a hole-like portion. The pair of movable housings 41 for signal terminals abut against each other at their Z2-side ends. The recess 44 of the pair of movable housings 41 for signal terminals forms a bottomed hole-like portion. Each of the pair of movable housings 41 for signal terminals has a stop portion 44B that forms the bottom of the recess 44 when it abuts against the other at its Z2-side end.

[0049] The movable housing 45 for the power terminals includes a peripheral wall 46 and a bottom block portion 47 that partially closes the opening on the Z2 side of the peripheral wall 46. The bottom block portions 47 are provided at both ends of the movable housing 45 for the power terminals in the X direction. A pair of bottom block portions 47 have a plurality of retaining holes 48H formed in them, forming a power terminal retaining portion 48. The power terminal retaining portion 48 holds the second end of the second power terminal 60. Multiple second power terminals 60 are individually passed through the plurality of retaining holes 48H.

[0050] The movable housing 45 for the power terminals does not have a bottom block portion 47 in the middle of the X direction. An opening 49 is formed in the middle of the movable housing 45 for the power terminals in the X direction. A pair of movable housings 41 for signal terminals are housed in this opening 49.

[0051] The movable housing 45 for the power terminals has a retaining wall 50. The retaining wall 50 is located between the bottom block portion 47 and the opening 49. The retaining projections 43 of the pair of movable housings 41 for signal terminals catch on the retaining wall 50, preventing the pair of movable housings 41 for signal terminals from coming out on the Z2 side beyond the opening 49.

[0052] One of the pair of movable signal terminal housings 41, the movable signal terminal housing 41L, is an example of the first movable housing. The other of the pair of movable signal terminal housings 41, the movable signal terminal housing 41R, is an example of the second movable housing. Hereinafter, they may be referred to as the first movable housing 41L and the second movable housing 41R. The movable housing 40 has the first movable housing 41L and the second movable housing 41R arranged along the Y direction.

[0053] A pair of movable signal terminal housings 41 are housed within the peripheral wall 46 through the Z1-side opening of the peripheral wall 46. Also, when the first connector 10 and the second connector 30 are mated, the tip of the first connector 10 is housed within the peripheral wall 46 through the Z1-side opening of the peripheral wall 46. The portions of the peripheral wall 46 located at both ends in the X direction are corrective pressing portions 46A that receive the corrective housing pressing portion 14 of the first connector 10.

[0054] As shown in Figure 7, a fitting recess 51 is provided on the lower side of the corrective pressing portion 46A, into which the corrective housing pressing portion 14 fits. In addition, projections supported by the housing support portion 37 may be provided at the four corners of the lower part of the movable housing 45 for the power terminal.

[0055] As shown in Figure 4, the peripheral wall 33 of the fixed housing 32 and the peripheral wall 46 of the movable housing 45 for the power terminals face each other. The initial state is when the movable housing 40 is not misaligned in the XY direction relative to the fixed housing 32. In the initial state of the movable housing 40, as shown in Figure 4, the peripheral walls 33 and 46 face each other with a gap D1 between them. The gap D1 is, for example, the same as the amount of movement of the movable housing 40 in the Y direction. The gap D1 allows the movable housing 40 to move relative to the fixed housing 32.

[0056] As shown in Figure 4, the inner surface of the peripheral wall 46 of the movable housing 45 for the power terminals and the outer surface 42HA of the block portion in which the retaining hole 42H of the movable housing 41 for the signal terminals are formed face each other. In the initial state of the movable housing 40, as shown in Figure 4, the inner surface of the peripheral wall 46 and the outer surface 42HA of the movable housing 41 for the signal terminals face each other with a gap D2 between them. The gap D2 is, for example, smaller than the gap D1. The gap D2 is used for impedance matching due to the difference in substrate distance in the Z direction.

[0057] The second signal terminal 52 and the second power terminal 60 are each formed into a predetermined shape by press working (punching and bending) a flat plate of a conductive material such as metal. Such a flat plate is curved in the YZ plane and extends generally in the Z direction so that it is elongated in the Z direction. The cross-section of such a flat plate is, for example, rectangular. In the rectangular cross-section, the shorter direction is the plate thickness direction, and the longer direction is the plate width direction. The second signal terminal 52 and the second power terminal 60 are each positioned such that the plate width direction of the flat plate is aligned with the X direction. Furthermore, the thickness of the flat plate in the Y direction in the portion of the flat plate that extends parallel to the Z direction is the plate thickness. Therefore, in this embodiment, the Z direction is the extension direction of the plate material, the Y direction is the plate thickness direction of the plate material, and the X direction is the plate width direction of the plate material.

[0058] The second signal terminal 52 includes a first end held by the fixed housing 32, a second end held by the movable housing 40, and a connecting portion that connects the first end and the second end. When the movable housing 40 moves along the X or Y direction, the connecting portion elastically deforms, allowing the second end to follow the movable housing 40.

[0059] The first end of the second signal terminal 52 has a board connection portion 53 that is connected to the second substrate B2 and a press-fit projection 54 that is held by the fixed housing 32. The board connection portion 53 is exposed below the fixed housing 32. The board connection portion 53 is formed in a shape that extends along the main surface of the second substrate B2 and is formed to be surface-mountable on the second substrate B2. The board connection portion 53 may also be formed in the shape of a pin that can be connected to the second substrate B2 through a through-hole. The press-fit projection 54 is press-fitted and held in the holding hole 35H of the fixed housing 32. The press-fit projection 54 protrudes outward from both outer edges along the board width direction (X direction).

[0060] The second end of the second signal terminal 52 has a second spring contact portion 55 that connects to the first signal terminal 16 of the first connector 10, and a press-fit projection 56 that is held in the movable housing 40. The press-fit projection 56 is press-fitted and held in the holding hole 42H of the movable housing 41 for the signal terminal. The press-fit projection 56 protrudes outward from both outer edges along the plate width direction (X direction).

[0061] An elastic portion 57 is provided at the connection point of the second signal terminal 52. The elastic portion 57 has a trapezoidal wave-shaped section. The elastic portion 57 is offset in the Y direction from the first end to the second end.

[0062] The second power terminal 60 has a larger conductor cross-sectional area than the second signal terminal 52. The second power terminal 60 is also held in a press-fit state in the fixed housing 32. The second power terminal 60 also has a first end held in the fixed housing 32, a second end held in the movable housing 40, and a connecting portion that connects the first end and the second end.

[0063] The first end of the second power terminal 60 has a board connection portion 61 and a press-fit projection 62. The board connection portion 61 is connected to the second board B2. The press-fit projection 62 is press-fitted and held in the power terminal holding portion 36 of the fixed housing 32.

[0064] The second end of the second power terminal 60 has a tab portion 63 and a locking projection 64. The tab portion 63 is inserted into and connected to the cylindrical portion 23 of the first power terminal 21. The locking projection 64 locks onto the periphery of the retaining hole 48H of the movable housing 45 for the power terminal.

[0065] The connecting portion of the second power terminal 60 has an elastic portion 65. When the movable housing 40 moves, the elastic portion 65 deforms, allowing the second end to follow the movable housing 40.

[0066] The fixed housing 32 supports the movable housing 40 from the Z2 side. For example, the fixed housing 32 supports the movable housing 40 from the Z2 side by contacting a projection of the movable housing 40 from the Z2 side. The fixed housing 32 restricts the movement of the movable housing 40 toward Z2.

[0067] <Regarding the mating of the first connector and the second connector> The mating of the first connector 10 and the second connector 30 will be explained with further reference to Figures 9 to 12. Figure 9 is a cross-sectional view showing the connector device 100 just before mating. Figure 10 is a cross-sectional view showing the connector device 100 at the first mating dimension. Figure 11 is a cross-sectional view showing the connector device 100 in a state between the first and second mating dimensions. Figure 12 is a cross-sectional view showing the connector device 100 at the second mating dimension.

[0068] When connecting the first connector 10 and the second connector 30, the worker moves the first connector 10 and the second connector 30 relative to each other along the mating direction. Here, as shown in Figure 4, the first connector 10 and the second connector 30 are separated in the Z direction, and the substrates B1 and B2 are moved relative to each other along the mating direction.

[0069] The signal terminal holding portion 12 of the first connector 10 and the signal terminal holding portion 42 of the second connector 30 are mated together, and the power terminal holding portion 13 of the first connector 10 and the power terminal holding portion 48 of the second connector 30 are mated together. Before these matings occur, the positional misalignment in the X and Y directions is corrected by the contact between the corrective housing pressing portion 14 and the corrective pressed portion 46A.

[0070] The corrective housing pressing portion 14 is the portion that first contacts the second connector 30 when the first connector 10 and the second connector 30, which are located at different positions in the Z direction, approach each other along the Z direction. By providing the corrective housing pressing portion 14, the misalignment between the movable housing 40 of the second connector 30 and the first connector 10 in the X and Y directions is corrected before contact between the terminals.

[0071] If the first connector 10 and the second connector 30 are misaligned in the X or Y direction, the corrective housing pressing part 14 presses the corrective pressed part 46A of the movable housing 40, causing the movable housing 40 to move along the XY plane relative to the fixed housing 32, thereby correcting the misalignment. Here, the first connector housing 11 presses the movable housing 45 for the power terminals, and the movable housing 45 for the power terminals presses the movable housing 41 for the signal terminals, thereby correcting the misalignment of the housings. When the movable housing 41 for the signal terminals is pressed, the signal terminal holding part 42 presses the second end of the second signal terminal 52, causing it to follow the movement of the movable housing 40. Therefore, the signal terminal holding part 42 is a corrective terminal pressing part that causes the second end of the second signal terminal 52 to follow the movement of the movable housing 40 when the corrective housing pressing part 14 presses the corrective pressed part 46A.

[0072] More specifically, in the state shown in Figure 4, when the movable housing 41 for the signal terminal moves to the Y1 side, the second ends of each of the pair of second signal terminals 52 aligned in the Y direction also move to the Y1 side. The second end of the second signal terminal 52 on the Y2 side is pushed to the Y1 side by the outer surface in the Y direction of the inner circumferential surface of the retaining hole 42H (the surface on the Y2 side). The second end of the second signal terminal 52 on the Y1 side is pushed to the Y1 side by the inner surface in the Y direction of the inner circumferential surface of the retaining hole 42H (the surface on the Y2 side) and the bottom surface of the retaining groove 42G. The corrective housing pressing part 14, the corrective pressed part 46A, and the corrective terminal pressing part 42 constitute a corrective section that corrects the misalignment of the first connector 10 and the second connector 30 in the X and Y directions.

[0073] Along the Z-direction, the corrective housing pressing portion 14 is positioned so that it contacts the corrective pressed portion 46A before the housing pressing portion 15 contacts the pressed portion 44A. For example, in the Z-direction, the sum of the distance from the first substrate B1 to the tip of the corrective housing pressing portion 14 and the distance from the second substrate B2 to the tip of the corrective pressed portion 46A is defined as the first sum. The sum of the distance from the first substrate B1 to the tip of the housing pressing portion 15 and the distance from the second substrate B2 to the tip of the pressed portion 44A is defined as the second sum. Since the first sum is greater than the second sum, the corrective housing pressing portion 14 can be positioned so that it contacts the corrective pressed portion 46A before the housing pressing portion 15 contacts the pressed portion 44A.

[0074] Furthermore, if the first connector 10 and the second connector 30 are not misaligned in the X or Y direction, positional correction may not be performed.

[0075] If there is no misalignment, or if the misalignment has been corrected, when the first connector 10 moves further toward the second connector 30 towards Z2, the first spring contact portion 18 and the second spring contact portion 55 come into contact. In this state, when the first connector 10 moves further toward the second connector 30 towards Z2, the first spring contact portion 18 moves over the second spring contact portion 55. As a result, as shown in Figure 9, the first signal terminal 16 and the second signal terminal 52 are electrically connected. At this time, the first power terminal 21 and the second power terminal 60 are also electrically connected.

[0076] In this state, if the first connector 10 moves further toward the Z2 side toward the second connector 30, the housing pressing portion 15 of the first connector 10 will come into contact with the pressed portion 44A of the second connector 30, as shown in Figure 10.

[0077] Here, the distance between boards B1 and B2 (hereinafter referred to as the board-to-board distance) may change depending on the other components. A maximum and minimum allowable distance is set for the board-to-board distance.

[0078] For example, the distance between the boards shown in Figure 10 may be the maximum allowable distance. In other words, if the distance between the boards is the maximum value, the mating of the first connector 10 and the second connector 30 may be completed in the state shown in Figure 10. In the state shown in Figure 10, the mating dimensions of the first connector 10 and the second connector 30 are the first mating dimensions.

[0079] If the distance between the boards is less than the maximum value, the first connector 10 moves further toward the second connector 30 towards Z2 than in the state shown in Figure 10. The state shown in Figure 11 is when the first connector 10 has moved further toward the second connector 30 towards Z2 than in the state shown in Figure 10. Also, the state shown in Figure 12 is when the first connector 10 has moved further toward the second connector 30 towards Z2 than in the state shown in Figure 11.

[0080] The state shown in Figure 12 is the mating state when the distance between the boards is at its minimum. When the distance between the boards is at its minimum, mating between the first connector 10 and the second connector 30 is completed in the state shown in Figure 12. The state in Figure 12 is the state where the mating dimension between the first connector 10 and the second connector 30 is the second mating dimension, which is larger than the first mating dimension. In the Z direction, the first connector 10 and the second connector 30 take on a mating dimension between the first mating dimension (the mating dimension shown in Figure 10) and the second mating dimension (the mating dimension shown in Figure 12), which is larger than the first mating dimension.

[0081] When the first connector 10 moves towards Z2 from the state in Figure 10 to the state in Figure 11 or Figure 12, the housing pressing portion 15 of the first connector housing 11 presses the pressed portion 44A of the second connector housing 31. As a result, the second connector housing 31 moves. This causes the terminal pressing portion 42GA of the second connector housing 31 to press the second signal terminal 52, and the shape of the first spring contact portion 18, the second spring contact portion 55, and the portion in between changes.

[0082] More specifically, the pressed portion 44A is provided at the tip of the first movable housing 41L and the tip of the second movable housing 41R. When the pressed portion 44A is pressed by the housing pressing portion 15, the tip of the first movable housing 41L and the tip of the second movable housing 41R move apart from each other in the Y direction. Here, the gap D2 between the inner surface of the peripheral wall 46 and the outer surface 42HA of the movable housing 41 for signal terminals is used to move the tip of the first movable housing 41L and the tip of the second movable housing 41R apart in the Y direction. Here, when the housing pressing portion 15 presses the pressed portion 44A, the pair of movable housings 41 for signal terminals move so as to rotate in opposite directions around the abutment portion 44B at the Z2 side end. As a result, the tip of the first movable housing 41L and the tip of the second movable housing 41R move apart from each other in the Y direction. At this time, the bottom surface 42GA of the retaining groove 42G pushes the second signal terminal 52 outward in the Y direction (towards the first signal terminal 16). Therefore, in this case, the bottom surface 42GA of the retaining groove 42G is the terminal pressing portion 42GA. When the housing pressing portion 15 presses the pressed portion 44A, the pair of movable housings 41 for signal terminals may be configured to slide in the Y direction without rotating.

[0083] In the configuration shown in Figure 10, the contact portion between the first signal terminal 16 and the second signal terminal 52 has a first spring contact portion 18 and a second spring contact portion 55 that are separated from each other along the Z direction. The first signal terminal 16 has a first extended portion 20 that extends between the first spring contact portion 18 and the second spring contact portion 55. The second signal terminal 52 has a second extended portion 58 that extends between the first spring contact portion 18 and the second spring contact portion 55. The second extended portion 58 is provided at the second end of the second signal terminal 52.

[0084] The distance between the first spring contact portion 18 and the second spring contact portion 55 in the Z direction is the first distance (the distance shown in Figure 10) when the first fitting dimension is reached. When the state changes from the state shown in Figure 10 to the state shown in Figure 11 or Figure 12, the distance between the first spring contact portion 18 and the second spring contact portion 55 along the Z direction increases. The distance between the first spring contact portion 18 and the second spring contact portion 55 in the Z direction is the second distance (the distance shown in Figure 12) when the second fitting dimension is reached. The second distance is greater than the first distance. Therefore, the distance between the first spring contact portion 18 and the second spring contact portion 55 in the Z direction is one of the distances between the first distance and the second distance (including the first and second distances).

[0085] The first extended portion 20 and the second extended portion 58 are separated from each other along the Y direction, which is perpendicular to the Z direction, when the mating dimension is set to the first mating dimension. The housing pressing portion 15 presses the pressed portion 44A of the second connector housing 31 when the mating dimension between the first connector 10 and the second connector 30 is greater than the first mating dimension. The terminal pressing portion 42GA presses the second signal terminal 52 when the pressed portion 44A is pressed by the housing pressing portion 15, bringing the second extended portion 58 closer to the first extended portion 20.

[0086] <Changes in the connection status of the first and second signal terminals> The changes in the connection state of the first signal terminal 16 and the second signal terminal 52 will be explained with further reference to Figures 13 to 15. Figure 13 is an explanatory diagram showing the changes in the connection state of the first signal terminal 16 and the second signal terminal 52 due to a change in the mating dimension. Figure 14 is an explanatory diagram showing the connection state of the first signal terminal 16 and the second signal terminal 52 when the state is between the first mating dimension and the second mating dimension. Figure 15 is an explanatory diagram showing the connection state of the first signal terminal 16 and the second signal terminal 52 when the mating dimension is the second mating dimension. The first signal terminal 16 and the second signal terminal 52 in Figures 13 to 15 are the first signal terminal 16 and the second signal terminal 52 of the Y2 side pair.

[0087] In Figure 13, the left-hand pair of the first signal terminal 16A and the second signal terminal 52A is in the state corresponding to the first mating dimension shown in Figure 10. In Figure 13, the right-hand pair of the first signal terminal 16C and the second signal terminal 52C is in the state corresponding to the second mating dimension shown in Figure 12. In Figure 13, the middle pair of the first signal terminal 16B and the second signal terminal 52B is in the state corresponding to a mating dimension between the first and second mating dimensions shown in Figure 11.

[0088] In this disclosure, the contact portion between the first signal terminal 16 and the second signal terminal 52 includes a first spring contact portion 18 and a second spring contact portion 55. As shown in Figure 13, when viewed from the X direction, a space CS is created surrounded by the first spring contact portion 18, the second spring contact portion 55, the first extended portion 20, and the second extended portion 58. When the mating dimensions change, the shape of the space CS changes.

[0089] In Figure 14, the set of the first signal terminal 16B and the second signal terminal 52B shown by the solid line corresponds to the set of the first signal terminal 16B and the second signal terminal 52B in Figure 13, that is, the set of the first signal terminal 16 and the second signal terminal 52 in the state shown in Figure 11. In Figure 14, the set of the first signal terminal 16B1 and the second signal terminal 52B1 shown by the dashed line represents a hypothetical case in which the housing pressing portion 15 and the pressed portion 44A are not provided. As can be seen from Figure 14, in the set of the first signal terminal 16B and the second signal terminal 52B, the size of the space CS is smaller than in the set of the first signal terminal 16B1 and the second signal terminal 52B1 because the second extended portion 58 is closer to the first extended portion 20.

[0090] Similarly, in Figure 15, the set of the first signal terminal 16C and the second signal terminal 52C shown by the solid line corresponds to the set of the first signal terminal 16C and the second signal terminal 52C in Figure 13, that is, the set of the first signal terminal 16 and the second signal terminal 52 in the state shown in Figure 12. In Figure 15, the set of the first signal terminal 16C1 and the second signal terminal 52C1 shown by the dashed line represents a hypothetical case in which the housing pressing portion 15 and the pressed portion 44A are not provided. As can be seen from Figure 15, in the set of the first signal terminal 16C and the second signal terminal 52C, the size of the space CS is smaller than in the set of the first signal terminal 16C1 and the second signal terminal 52C1 because the second extending portion 58 is closer to the first extending portion 20.

[0091] Here, the inventors of the present invention discovered that a change in the shape of the space CS, more specifically, a change in the size of the space CS, is one of the causes of a change in impedance. They then found that impedance matching can be achieved by keeping the size of the space CS as constant as possible.

[0092] In this case, if the housing pressing portion 15 and the pressed portion 44A are not provided, the size of the space CS is considered to increase monotonically as the fitting dimension changes from the first fitting dimension to the second fitting dimension. Furthermore, the rate of increase in the size of the space CS is considered to be proportional to the distance between the first spring contact portion 18 and the second spring contact portion 55.

[0093] In contrast, the present disclosure provides a housing pressing portion 15 and a pressed portion 44A, which suppresses the increase in the size of the space CS when changing from the first mating dimension to the second mating dimension. As a result, even if the mating dimension changes according to the distance between substrates, the change in impedance can be suppressed.

[0094] <Effects, etc.> With the connector device 100 configured as described above, the distance between the two spring contact portions 18 and 55 changes due to differences in the distance between the substrates, and the impedance may change. This can occur because the size of the space CS between the two spring contact portions 18 and 55 (the area of ​​the space CS viewed from the X direction) changes. In this disclosure, when the two spring contact portions 18 and 55 move away from each other, the extension portions 20 and 58 between the two spring contact portions 18 and 55 move closer together, thereby suppressing the change in the size of the space CS between the two spring contact portions 18 and 55. This suppresses the change in impedance due to tolerances in the distance between the substrates. In fact, it has been experimentally confirmed that the connector device 100 of this disclosure can suppress impedance fluctuations when the distance between the substrates changes compared to the case where the extension portions 20 and 58 cannot be brought closer together.

[0095] Furthermore, the pressed portion 44A and the terminal pressing portion 42GA are provided on the movable housing 40, and when the pressed portion 44A is pressed by the housing pressing portion 15, the movable housing 40 moves relative to the fixed housing 32. By moving the movable housing 40 relative to the fixed housing 32, impedance matching related to the tolerance of the distance between substrates can be achieved.

[0096] Furthermore, when the pressed portion 44A is pressed by the housing pressing portion 15, the tip of the first movable housing 41L and the tip of the second movable housing 41R move apart from each other in the Y direction. This allows for impedance matching to be achieved collectively for the second signal terminals 52 held by the two movable housings 41L and 41R.

[0097] Furthermore, a correction section is provided to correct the misalignment of the first connector 10 and the second connector 30 in the X and Y directions. This makes it possible to achieve impedance matching due to the difference in distance between the substrates in a connector device 100 having a floating structure that can absorb misalignment in a direction parallel to the substrate surface.

[0098] Furthermore, the corrective housing pressing portion 14 is positioned so that it contacts the corrective pressed portion 46A before the housing pressing portion 15 contacts the pressed portion 44A along the Z direction. This allows impedance matching for the misalignment in the Z direction to be achieved after the correction of misalignments in the X and Y directions is complete.

[0099] Furthermore, the first end of the second power terminal 60 is held by the fixed housing 32, and the second end of the second power terminal 60 is held by the movable housing 45 for power terminals. This makes it easier to achieve impedance matching of the second signal terminal 52 by separating the movable housing 41 for the second signal terminal 52, for which impedance matching is desired, from the movable housing 45 for the second power terminal 60, for which impedance matching is less necessary.

[0100] [Note] Figure 16 is a cross-sectional view showing a modified connector device 200.

[0101] In the connector device 200, the shapes of the first connector 110 and the second connector 130 are partially different from those of the first connector 10 and the second connector 30. Specifically, in the connector device 200, the elastic portion 157 of the second signal terminal 152 does not have a trapezoidal corrugated portion, but is instead formed in a stepped shape. The second signal terminal 152 is offset once in the Y direction inside the holding hole 142H. In addition, the first signal terminal 116 is provided with a trapezoidal corrugated portion. This makes it easier to deform the first signal terminal 116 and the second signal terminal 152 to bring the first extended portion 20 of the first signal terminal 116 and the second extended portion 58 of the second signal terminal 152 closer together.

[0102] Furthermore, in the connector device 200, the retaining hole 142H of the movable housing 141 for the signal terminal is shorter than the retaining hole 42H along the Z direction. The length of the portion of the second signal terminal 152 that extends Z1 beyond the retaining hole 142H is longer than the length of the portion of the second signal terminal 52 that extends Z1 beyond the retaining hole 42H. In the second signal terminal 152, the ratio of the portion that extends Z1 beyond the retaining hole 142H to the portion that fits into the retaining hole 142H is greater than the ratio of the portion that extends Z1 beyond the retaining hole 42H to the portion that fits into the retaining hole 42H in the second signal terminal 52. Here, in the second signal terminal 152, the portion that extends Z1 beyond the retaining hole 142H is more than twice as long as the portion that fits into the retaining hole 142H.

[0103] Furthermore, in the connector device 200, the dimension of the first connector 110 in the Z direction is longer than the dimension of the first connector 10 in the Z direction. The length of the first signal terminal 116 in the Z direction and the length of the second signal terminal 152 in the Z direction are approximately the same. For example, the length of the first signal terminal 116 in the Z direction may be between 80% and 120%, between 90% and 110%, or between 95% and 105% of the length of the second signal terminal 152 in the Z direction.

[0104] Similar to the connector device 100, the connector device 200 can also suppress changes in the size of the space CS between the two spring contact portions 18 and 55 by having the first connector housing 111 push the second connector housing 131 when the mating dimensions change.

[0105] Furthermore, the configurations described in each of the above embodiments and modifications can be combined as appropriate, as long as they do not contradict each other. [Explanation of Symbols]
