[0009] [Description of Embodiments of the Present 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 connector includes a mating connector that mates with the connector, the connector including a housing and a signal terminal held by the housing, the mating connector including a mating housing that mates with the housing and a mating signal terminal that is held by the mating housing and connected to the signal terminal, the signal terminal having a first terminal portion that extends in a mating direction between the connector and the mating connector and a first connecting plate portion that is connected to the first terminal portion along the mating direction, a second terminal portion extending in a mating direction, and a second connecting plate portion connected to the second terminal portion along the mating direction, wherein the first terminal portion and the second terminal portion form parallel plate portions aligned in a first direction intersecting the mating direction, the first connecting plate portion and the second connecting plate portion extending in opposite directions from the parallel plate portions, and in a second direction intersecting the mating direction and the first direction, the dimensions of the first terminal portion are smaller than the dimensions of the first connecting plate portion, and the dimensions of the second terminal portion are smaller than the dimensions of the second connecting plate portion.

[0012] According to the connector device of (1), impedance may vary between the parallel plate portions of the signal terminal and the mating signal terminal and the non-parallel plate portions. By making the dimensions of the first terminal portion that forms the parallel plate portion smaller than the dimensions of the first connecting plate portion that does not form the parallel plate portion in the second direction, and by making the dimensions of the second terminal portion that forms the parallel plate portion smaller than the dimensions of the second connecting plate portion that does not form the parallel plate portion, impedance mismatch can be suppressed. Therefore, the connector device can achieve good communication performance.

[0013] (2) In the connector device of (1), the housing may have a first retaining groove for receiving the first terminal, and the mating housing may have a second retaining groove for receiving the second terminal, and the sidewall of the first retaining groove may have a smaller dimension than the first terminal, and the sidewall of the second retaining groove may have a smaller dimension than the second terminal in the first direction. This makes it easier to suppress impedance mismatch in the parallel plate portion. Furthermore, it is possible to prevent the first terminal from climbing up onto the sidewall of the second retaining groove, and the second terminal from climbing up onto the sidewall of the first retaining groove.

[0014] (3) In the connector device of (1) or (2), the first terminal portion may have a first base plate portion extending in the mating direction and a first spring contact portion provided further distal than the first base plate portion, and the second terminal portion may have a second base plate portion extending in the mating direction and a second spring contact portion provided further distal than the second base plate portion, and when the signal terminal and the mating signal terminal are connected, the first base plate portion and the second base plate portion may be spaced apart from each other in the first direction, and the first spring contact portion may contact the second base plate portion and the second spring contact portion may contact the first base plate portion. This provides two contact portions, thereby improving connection reliability between the signal terminal and the mating signal terminal.

[0015] (4) In the connector device of (3), the housing may have a first retaining groove for receiving the first terminal portion, and the mating housing may have a second retaining groove for receiving the second terminal portion, and when the signal terminal and the mating signal terminal are connected, the first spring contact portion may protrude outward from the first retaining groove beyond a tip end surface of a side wall of the first retaining groove, and the second spring contact portion may protrude outward from the second retaining groove beyond a tip end surface of a side wall of the second retaining groove. This eliminates the need for a wall portion covering the side of the spring contact portion, making it easier to suppress impedance mismatch in the spring contact portion.

[0016] (5) In the connector device of either (3) or (4), the housing may have a first retaining groove for receiving the first terminal portion, the mating housing may have a second retaining groove for receiving the second terminal portion, the first retaining groove may have a first base plate groove portion corresponding to the first base plate portion and a first spring-shaped portion groove portion corresponding to the first spring contact portion, the second retaining groove may have a second base plate groove portion corresponding to the second base plate portion and a second spring-shaped portion groove portion corresponding to the second spring contact portion, and in the first direction, a depth of the first spring-shaped portion groove portion may be deeper than a depth of the first base plate groove portion, and a depth of the second spring-shaped portion groove portion may be deeper than a depth of the second base plate groove portion. When the signal terminal and the mating signal terminal are mated, the spring contact portions come into contact with each other. In the first direction, the depth of the first spring-shaped portion groove is deeper than the depth of the first base plate portion groove, and the depth of the second spring-shaped portion groove is deeper than the depth of the second base plate portion groove, so that the spring contact portions can come into contact with each other during mating and deflected portions can be released. Also, the space between the spring contact portions and the bottom surface of the groove can be increased, making it easier to suppress impedance mismatch at the spring contact portions.

[0017] (6) In any one of the connector devices (1) to (5), the signal terminal may have a retained portion provided with a press-fit protrusion that is press-fitted into the housing, and a third connecting plate portion connected to the retained portion, and the dimension of the third connecting plate portion may be smaller than the dimension of the first connecting plate portion in the second direction. The portion provided with the press-fit protrusion is a portion that is press-fitted into the resin wall, and impedance is likely to change. By reducing the plate width of the third connecting plate portion connected to the retained portion, it is easier to suppress impedance mismatch around the retained portion.

[0018] (7) In the connector device of (6), the third connecting plate may have a first portion and a second portion that are different in size in the second direction. This makes it easier to prevent misalignment around the held portion.

[0019] (8) In the connector device of any one of (1) to (7), the connector may be a floating connector, the housing may include a fixed housing and a movable housing movable relative to the fixed housing along the first direction and the second direction, the signal terminal may include a first end held by the fixed housing, a second end including the first terminal portion and held by the movable housing, and a connecting portion connecting the first end and the second end, the connecting portion being elastically deformed when the movable housing moves along the first direction and the second direction, and the second end may follow the movable housing. This makes it possible to suppress impedance mismatching of the signal terminal in the floating connector, and to achieve good communication performance in a connector device equipped with a floating connector.

[0020] [Details of the embodiments of the present disclosure] Specific examples of the connector device of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0021] First Embodiment A connector device according to a first embodiment will be described below.

[0022] <Connector device> The overall configuration of the connector device will be described with reference to Figures 1 to 6. Figure 1 is an exploded perspective view showing a floating connector 10 according to a first embodiment and a connector device 100 including the same. 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 taken along line IV-IV in Figure 2. Figure 5 is a cross-sectional view taken along line V-V in Figure 2. Figure 6 is a cross-sectional view taken along line VI-VI in Figure 4. In each figure, mutually orthogonal X, Y, and Z directions are shown.

[0023] The connector device 100 includes a connector 10 and a mating connector 80 that mates with the connector 10. In this embodiment, an example is described in which the connector 10 is a floating connector 10. As shown in FIG. 2 and other figures, in this embodiment, the floating connector 10 and the mating connector 80 are described as board connectors that are electrically connected to boards B1 and B2, respectively. When the floating connector 10 and the mating connector 80 are mated, terminals of the floating connector 10 and terminals of the mating connector 80 are electrically connected. As a result, the boards B1 and B2 to which the floating connector 10 and the mating connector 80 are connected are electrically connected to each other. The floating connector 10 and the mating connector 80 may be connectors other than board connectors.

[0024] The floating connector 10 and the mating connector 80 are mated by moving toward each other in a mating direction. In this embodiment, the mating direction is a direction perpendicular to the main surfaces of the boards B1 and B2, and is indicated by the Z direction in each figure. Hereinafter, the Z direction may be referred to as the up-down direction. The X and Y directions in each figure are directions perpendicular to the mating direction and are directions along the main surfaces of the boards B1 and B2. Note that the mating direction of the floating connector 10 and the mating connector 80 may be a direction other than the Z direction.

[0025] <Floating Connector> The floating connector 10 will be described with further reference to Fig. 7 to Fig. 9. Fig. 7 is an exploded perspective view showing the floating connector 10 shown in Fig. 1. Fig. 8 is a perspective view showing a signal terminal 40 according to the first embodiment. Fig. 9 is a perspective view showing a power terminal 60 according to the first embodiment.

[0026] The floating connector 10 includes a housing and a plurality of signal terminals 40 held by the housing. Here, the floating connector 10 includes a fixed housing 20 and a movable housing 30 as housings. The signal terminals 40 are terminals for signal transmission. In addition to the signal terminals 40, the floating connector 10 also includes a plurality of power terminals 60. The power terminals 60 are terminals for power supply. The fixed housing 20 is fixed to the board B1 via a fixture 70. The movable housing 30 is provided so as to be movable relative to the fixed housing 20. The plurality of signal terminals 40 and the plurality of power terminals 60 are bridged between the fixed housing 20 and the movable housing 30. In this embodiment, the movable housing 30 is supported in a floating state at a predetermined position relative to the fixed housing 20 via the signal terminals 40 and the power terminals 60. In this way, the movable housing 30 is supported so as to be movable relative to the fixed housing 20.

[0027] The movable housing 30 is movable relative to the fixed housing 20 along a first direction that intersects with the mating direction. In this embodiment, the movable housing 30 is movable relative to the fixed housing 20 along a second direction that intersects with the mating direction and the first direction. In this embodiment, the Y direction indicates the first direction, and the X direction indicates the second direction. However, the movable housing 30 only needs to be movable along the first direction, and does not have to be movable along both the first and second directions.

[0028] In this embodiment, the movable housing 30 is movable in both the first direction and the second direction without being restricted by the other. That is, the movable housing 30 is movable relative to the fixed housing 20 not only in the X direction and the Y direction, but also in directions inclined relative to the X direction and the Y direction within the XY plane. The movable housing 30 is movable relative to the fixed housing 20 in any direction within a plane including the first direction and the second direction. It can also be understood that the movement vector indicating the direction and amount of movement of the movable housing 30 can be expressed as the sum of the movement vector in the first direction and the movement vector in the second direction.

[0029] In this embodiment, a plurality of signal terminals 40 and a plurality of power terminals 60 are arranged in the X and Y directions. The power terminals 60 are arranged on both sides of the signal terminals 40 in the X direction. For example, the number of parallel signal terminals 40 in the X direction is 10 or more (75 in this example), and the number of parallel signal terminals 40 in the Y direction is two. On one side and the other side of the signal terminals 40 in the X direction, the power terminals 60 are arranged in two rows in each of the X and Y directions. However, the number of parallel terminals 40, 60 in the X direction and the number of parallel terminals 40, 60 in the Y direction are not particularly limited and can be set as appropriate. As in the example embodiment, it is preferable that the number of parallel signal terminals 40 in the X direction be greater than the number of parallel signal terminals 40 in the Y direction.

[0030] A pair of adjacent signal terminals 40 along the X direction are oriented in the same direction. A pair of adjacent signal terminals 40 along the Y direction are oriented in opposite directions. Similarly, a pair of adjacent power terminals 60 along the X direction are oriented in the same direction, and a pair of adjacent power terminals 60 along the Y direction are oriented in opposite directions.

[0031] The fixed housing 20 is molded using an electrically insulating material such as synthetic resin. The fixed housing 20 includes a pair of wall portions 21X extending along the X direction and a pair of wall portions 21Y extending along the Y direction. The pair of wall portions 21X and the pair of wall portions 21Y are connected to form the peripheral wall 21. The peripheral wall 21 is open at its top and closed at its bottom. The fixed housing 20 includes a bottom block portion 22 that closes the lower opening of the peripheral wall 21. The bottom block portion 22 has multiple through holes. Therefore, the fixed housing 20 is cylindrically shaped, with the peripheral wall 21 open at its top and multiple through holes in its lower portion, each smaller than the upper opening. The lower portion of the movable housing 30 is positioned above the bottom block portion 22 in the internal space of the peripheral wall 21. The upper portion of the movable housing 30 protrudes upward from the upper opening of the fixed housing 20. In the X and Y directions, the inner surface of the peripheral wall 21 and the outer surface of the movable housing 30 face each other with a gap therebetween. This gap is, for example, the same as the amount of movement of the movable housing 30 in the X and Y directions.

[0032] The fixed housing 20 includes a signal terminal holding portion 23, a power terminal holding portion 24, and a fixture holding portion 29. Here, the signal terminal holding portion 23 and the power terminal holding portion 24 are provided on the bottom block portion 22, and the fixture holding portion 29 is provided on the outer surface of the wall portion 21Y.

[0033] The signal terminal holding portion 23 is a portion that holds the first end 42 of the signal terminal 40. The signal terminal holding portion 23 is a portion located in the middle of the bottom block portion 22 in the X direction, where a holding hole 23H is formed as a through hole. Two holding holes 23H are provided in the Y direction. Each of the two holding holes 23H has a plurality of first hole portions and one second hole portion. In each holding hole 23H, the plurality of first hole portions are aligned in the X direction. A plurality of signal terminals 40 aligned in the X direction are individually passed through the plurality of first hole portions. A second hole portion is located below the plurality of first hole portions. The plurality of first hole portions and the one second hole portion are continuous along the Z direction. A plurality of signal terminals 40 aligned in the X direction are collectively passed through the one second hole portion.

[0034] The power supply terminal holding portion 24 is a portion that holds the first end 61 of the power supply terminal 60. The power supply terminal holding portion 24 is a portion of the bottom block portion 22 that is located outside the signal terminal holding portion 23 in the X direction and that has a holding hole 24H formed as a through hole. A pair of power supply terminal holding portions 24 are provided, spaced apart from each other in the X direction. The signal terminal holding portion 23 is located between the pair of power supply terminal holding portions 24. The number of holding holes 24H is the same as the number of power supply terminals 60. Each holding hole 24H fits individually into one of the power supply terminals 60.

[0035] Here, the portion of the bottom block portion 22 located further outward in the X direction than the pair of power terminal holding portions 24 serves as a housing support portion 25 that supports the lower end of the movable housing 30. The housing support portion 25 is surrounded by the ends of the pair of wall portions 21X along the X direction and the wall portion 21Y.

[0036] The fixture holding portion 29 is a portion that holds the fixture 70. The fixture holding portion 29 is formed in the shape of a slot into which the fixture 70 can be inserted from above.

[0037] The movable housing 30 is molded using an electrically insulating material such as synthetic resin. The movable housing 30 is formed in a block shape that is longer in the X direction than in the Y direction. The movable housing 30 includes a signal terminal holder 31 and a power terminal holder 36.

[0038] The signal terminal holding portion 31 is a portion that holds the second ends 48 of the signal terminals 40. The signal terminal holding portion 31 includes a first block portion 32 and a second block portion 33. A plurality of holding holes 32H are formed in the first block portion 32. The second block portion 33 protrudes upward from the upper portion of the first block portion 32. The second block portion 33 is positioned between a pair of signal terminals 40 aligned in the Y direction. A plurality of first holding grooves 33G are formed in the outer surface of the second block portion 33 facing outward in the Y direction. The number of the holding holes 32H and the number of the first holding grooves 33G are the same and correspond one-to-one. Each holding hole 32H and each first holding groove 33G are continuous in the Z direction. The lower portions of the second ends 48 of the signal terminals 40 are individually passed through the plurality of holding holes 32H. The upper portions of the second ends 48 of the signal terminals 40 are individually received in the plurality of first holding grooves 33G.

[0039] Here, the signal terminal holding portion 31 includes a third block portion 34. The third block portion 34 protrudes downward from the lower portion of the first block portion 32. The third block portion 34 is located between a pair of signal terminals 40 aligned in the Y direction. Here, no groove such as the first holding groove 33G is formed in the third block portion 34. The outer surface of the third block portion 34 facing outward in the Y direction covers a plurality of signal terminals 40 collectively.

[0040] The power terminal holding portion 36 holds the second end 64 of the power terminal 60. The power terminal holding portion 36 has two holding bodies formed in the shape of a rectangular parallelepiped block. The two holding bodies are spaced apart from each other in the X direction. The signal terminal holding portion 31 is disposed between the two holding bodies. A plurality of holding holes 36H are formed in each holding body. A plurality of power terminals 60 are individually passed through the plurality of holding holes 36H. Here, the holding body has portions that connect to the sides of the first block portion 32 and the third block portion 34. The holding body does not have a portion that connects to the side of the second block portion 33.

[0041] Each retaining hole 36H includes a locking hole portion 36H1 and an accommodating hole portion 36H2. The upper portion of each retaining hole 36H is the locking hole portion 36H1, and the lower portion is the accommodating hole portion 36H2. The locking hole portion 36H1 is a portion that locks a portion of the power terminal 60. The accommodating hole portion 36H2 is a portion that fits another portion of the power terminal 60 without locking. Here, the dimensions of the locking hole portion 36H1 and the accommodating hole portion 36H2 are the same in the X direction. In the Y direction, the dimensions of the accommodating hole portion 36H2 are larger than the dimensions of the locking hole portion 36H1. The upper portion of the locking hole portion 36H1, extending around the periphery of the locking hole portion 36H1, forms a first locking surface 36A. A first locking claw 66A of the power terminal 60 is engaged with the first locking surface 36A. A portion of the lower portion of the locking hole 36H1 that extends around the periphery of the locking hole 36H1 serves as a second locking surface 36B. A second locking claw 66B of the power terminal 60 is engaged with the second locking surface 36B.

[0042] Here, the movable housing 30 includes a hood portion 37. The hood portion 37 surrounds the second block portion 33 of the signal terminal holding portion 31 and the portion of the power terminal 60 that protrudes above the power terminal holding portion 36. The hood portion 37 has a pair of wall portions 37X extending in the X direction and a pair of wall portions 37Y extending in the Y direction. The pair of wall portions 37X and the pair of wall portions 37Y are connected to form a peripheral wall of the movable housing 30. In the connector device 100, the tip of the mating connector 80 fits inside the hood portion 37. Both ends of the hood portion 37 along the X direction serve as guide receiving portions 38 that receive the guide portion 84 of the mating connector 80. As shown in FIG. 6 , a mating recess 38A into which the guide portion 84 fits is provided below the guide receiving portion 38. The mating recess 38A is a portion surrounded by the X-direction ends of the pair of wall portions 37X, one wall portion 37Y, and the power terminal holding portion 36. Furthermore, protrusions 39 supported by the housing support portion 25 are provided at the four corners of the lower part of the movable housing 30. Here, the pair of wall portions 37X and the pair of wall portions 37Y extend below the fitting recess 38A on the outer side of the power terminal holding portion 36 in the X direction of the movable housing 30. The protrusions 39 are provided on the lower part of the pair of wall portions 37X that are positioned outside the power terminal holding portion 36.

[0043] As shown in Fig. 4, the portion of the wall 21X that extends upward beyond the power terminal holding portion 24 faces the wall 36X of the movable housing 30. The wall 36X is a wall portion that is located further outward in the Y direction than the power terminal 60 among the wall portions that form the accommodating hole 36H2. When the movable housing 30 is in its initial position relative to the fixed housing 20 (a state in which there is no positional deviation with respect to the fixed housing 20, hereinafter referred to as the initial state), the walls 21X and 36X face each other with a distance DY therebetween, as shown in Fig. 4. The distance DY is, for example, the same as the amount of movement of the movable housing 30 in the Y direction.

[0044] Each of the signal terminals 40 and the power terminals 60 is formed into a predetermined shape by pressing (punching and bending) a flat plate made of a conductive material such as metal. The flat plate extends generally in the Z direction while bending in the YZ plane, making its length in the Z direction. The cross section of the flat plate is, for example, rectangular. The shorter dimension of the rectangular cross section is the thickness direction, and the longer dimension is the width direction. Each of the signal terminals 40 and the power terminals 60 is arranged with the width direction of the flat plate aligned with the X direction. Furthermore, the thickness of the flat plate in the Y direction at the portion extending parallel to the Z direction is the plate thickness. Therefore, in this embodiment, the mating direction is the extension direction of the plate material, the first direction (Y direction) is the thickness direction of the plate material, and the second direction (X direction) is the width direction of the plate material.

[0045] The signal terminal 40 includes a first end 42 held by the fixed housing 20, a second end 48 held by the movable housing 30, and a connecting portion 54 connecting the first end 42 and the second end 48. The first end 42 and the second end 48 are spaced apart from each other along the mating direction (here, the Z direction). The connecting portion 54 extends along the mating direction. When the movable housing 30 moves along the X direction or the Y direction, the connecting portion 54 elastically deforms, allowing the second end 48 to follow the movable housing 30.

[0046] The first end 42 has a board connecting portion 43 connected to the board B1 and a first held portion 44 held by the fixed housing 20. The board connecting portion 43 is exposed below the fixed housing 20. The board connecting portion 43 is formed in a shape extending along the main surface of the board B1 so as to be surface mountable to the board B1. The board connecting portion 43 may be formed in a pin shape or the like so as to be connectable to the board B1 via a through-hole. The first held portion 44 is press-fitted and held in the holding hole 23H of the fixed housing 20. The first held portion 44 has press-fit protrusions 45 at two locations along the longitudinal direction of the flat plate. Each press-fit protrusion 45 protrudes outward from both outer edges along the plate width direction (X direction). One of the two press-fit protrusions 45 is provided in a portion that fits within the first hole portion of the holding hole 23H, and the other is provided in a portion that fits within the second hole portion of the holding hole 23H.

[0047] The second end 48 has a first terminal portion 49 that connects with a mating signal terminal 85 of the mating connector 80, and a second held portion 51 that is held by the movable housing 30. The first terminal portion 49 has a first spring-shaped portion 50 that is a leaf spring that is bent in the plate thickness direction. The main portion of the second held portion 51 is located below the first spring-shaped portion 50, and in this case includes the portion that is inserted into the holding hole 32H.

[0048] Of the retaining hole 32H, inner surfaces facing opposite to each other along the plate thickness direction (here, the Y direction) of the signal terminal 40 are referred to as inner surfaces 32A and 32B. Here, the surface that is continuous with the bottom surface of the first retaining groove 33G is referred to as inner surface 32A. The distance between the inner surfaces 32A and 32B is greater than the plate thickness of the signal terminal 40. The distance between the inner surfaces 32A and 32B is greater than the dimension of the first spring-shaped portion 50 along the Y direction. This prevents the first terminal portion 49 having the first spring-shaped portion 50 from coming into contact with both the inner surface 32A and the inner surface 32B when passing through the retaining hole 32H.

[0049] The signal terminal 40 and the movable housing 30 are relatively movable in the mating direction. Here, the second held portion 51 does not have a press-fit protrusion that protrudes in the plate width direction and is press-fit into the movable housing 30, like the press-fit protrusion 45 of the first end 42. The second end 48 is held by the movable housing 30 with a holding force that is weaker than the holding force of the first end 42. For example, the first end 42 is held with greater difficulty in moving in the mating direction than the second end 48. For example, the first end 42 may be held by the fixed housing 20 so as not to move in the mating direction even by forces generated when the movable housing 30 moves. In contrast, the second end 48 may be held by the movable housing 30 so as to be movable in the mating direction by forces generated when the movable housing 30 moves.

[0050] The second retained portion 51 is bent in the plate thickness direction and contacts both the inner surface 32A and the inner surface 32B. The second retained portion 51 is, for example, in slidable contact with both the inner surface 32A and the inner surface 32B. More specifically, the second retained portion 51 has two bent portions 52. The two bent portions 52 are bent so that the main surfaces facing opposite to each other are on the inner circumferential side. By having the two bent portions 52, the second retained portion 51 can contact both the two opposite inner surfaces 32A and 32B of the retaining hole 32H, which is larger than the plate thickness. The portion of the second retained portion 51 above the two bent portions 52 extends upward while contacting the inner surface 32A or the bottom surface of the first retaining groove 33G continuous therewith. The portion of the second end 48 that extends from the second held portion 51 to the first spring-shaped portion 50 extends straight upward from the upper end of the second held portion 51 along the first holding groove 33G. Both sides of this portion in the X direction are separated from the adjacent signal terminal 40 by both side surfaces of the first holding groove 33G. The portion of the second held portion 51 below the lower bent portion 52 extends downward while contacting the inner surface 32B.

[0051] From one end of the signal terminal 40 to the other, the board connecting portion 43, the first held portion 44, the connecting portion 54, the second held portion 51, and the first terminal portion 49 are connected in this order. When assembling the floating connector 10, the signal terminal 40 is passed through the holding holes 23H and 32H in this order, starting from the first terminal portion 49. Because the first spring-shaped portion 50 is provided in the first terminal portion 49, the dimension of the first terminal portion 49 in the Y direction is greater than the plate thickness. To allow the first terminal portion 49 to pass through, the dimension of each holding hole 23H and 32H in the Y direction is greater than the plate thickness.

[0052] The connecting portion 54 connects the upper end of the first held portion 44 and the lower end of the second held portion 51. The upper end of the first held portion 44 and the lower end of the second held portion 51 are located at the same position along the Y direction. The lower portion of the connecting portion 54 extends straight upward from the upper end of the first held portion 44. The upper portion of the connecting portion 54 extends straight downward from the lower end of the second held portion 51. An elastic portion 55 is provided in the middle portion of the connecting portion 54 along the longitudinal direction.

[0053] The elastic portion 55 extends in a trapezoidal wave shape from the first end 42 to the second end 48. In the example shown in Fig. 4, the trapezoid is an isosceles trapezoid. The trapezoid may have a shape other than an isosceles trapezoid. The elastic portion 55 may have a shape other than a trapezoidal wave shape, such as a stepped shape.

[0054] The elastic portion 55 can also be considered to have two offset portions 55A and 55B. The offset portions 55A and 55B offset the position of the signal terminal 40, which extends straight in the Z direction, along the Y direction. Of the two offset portions 55A and 55B, the one located closer to the first end 42 is referred to as the first offset portion 55A, and the one located closer to the second end 48 is referred to as the second offset portion 55B. The position of the connecting portion 54 extending in the Z direction from the first end 42 to the second end 48 is shifted from the outside to the inside in the Y direction by the first offset portion 55A, and from the inside to the outside in the Y direction by the second offset portion 55B. The offset amount of the first offset portion 55A and the offset amount of the second offset portion 55B along the Y direction are the same. Furthermore, the first offset portion 55A and the second offset portion 55B are provided to have slopes of the same angle.

[0055] The first offset portion 55A is provided in the same direction as the offset portion of the second held portion 51. The offset amount of the first offset portion 55A and the offset amount of the offset portion of the second held portion 51 are the same along the Y direction. Here, the offset portions of the first offset portion 55A and the second held portion are provided to have slopes with similar angles. The slope of the first offset portion 55A may be provided to be steeper than the slope of the offset portion of the second held portion 51.

[0056] The fixed housing 20 and the movable housing 30 each have a retaining hole 23H, 32H through which the signal terminal 40 passes. The retaining hole 32H of the movable housing 30 is located on an extension of the first hole portion of the retaining hole 23H of the fixed housing 20. The first hole portion of the retaining hole 23H of the fixed housing 20 and the retaining hole 32H of the movable housing 30 have the same shape and size in the XY plane, excluding the guide surface. The first hole portion of the retaining hole 23H and the retaining hole 32H are located at the same position in the XY plane and overlap when viewed from the mating direction. For example, the size of the first hole portion of the retaining hole 23H and the retaining hole 32H in the X direction is approximately the same as (e.g., the same as or slightly smaller than) the width of the portion of the flat plate without the press-fit protrusion 45. The size of the first hole portion of the retaining hole 23H and the retaining hole 32H in the Y direction is the same as the offset amount of the second retained portion 51 and the elastic portion 55 in the Y direction.

[0057] The power terminal 60 has a conductor cross-sectional area larger than that of the signal terminal 40. The power terminal 60 is also held in a press-fit state in the fixed housing 20. Like the signal terminal 40, the power terminal 60 also has a first end 61 held in the fixed housing 20, a second end 64 held in the movable housing 30, and a connecting portion 67 connecting the first end 61 and the second end 64.

[0058] The first end 61 of the power supply terminal 60 is longer in the Y direction than the first end 42 of the signal terminal 40. The first end 61 of the power supply terminal 60 also has three orthogonal bent portions, and the portion between the first and third orthogonal bent portions fits into the holding hole 24H of the power supply terminal holding portion 24. The first end 61 has a board connecting portion 62 and a held portion 63. Here, a press-fit protrusion 63A is formed on the held portion 63, and the held portion 63 is press-fitted into the power supply terminal holding portion 24 of the fixed housing 20 and held therein.

[0059] The second end 64 of the power terminal 60 has a larger dimension in the plate thickness direction than the first end 61. For example, the flat plate constituting the power terminal 60 is folded and stacked at the second end 64 to increase the dimension in the plate thickness direction. Of the two layers of plate material constituting the second end 64, the plate material located on the outer side in the Y direction is referred to as the outer plate portion 64B, and the plate material located on the inner side in the Y direction is referred to as the inner plate portion 64C. In this example, the lower part of the inner plate portion 64C is connected to the connecting portion 67. The lower part of the outer plate portion 64B may also be connected to the connecting portion 67. For example, the second end 64 is inserted and held in the holding hole 36H of the power terminal holding portion 36 of the movable housing 30. The tip of the second end 64 is a tab terminal portion 65 that connects to the mating power terminal 90, and the portion closer to the first end 61 than the tab terminal portion 65 is a held portion 66 that is held by the movable housing 30.

[0060] The tab terminal portion 65 extends straight in the Z direction in the initial state. The mating power terminal 90 is provided with a spring-shaped portion 94, while the power terminal 60 does not have a spring-shaped portion. However, the power terminal 60 may also have a spring-shaped portion.

[0061] The held portion 66 is provided with a first locking claw 66A and a second locking claw 66B. The first locking claw 66A and the second locking claw 66B are provided on the outer plate portion 64B. The first locking claw 66A and the second locking claw 66B are spaced apart in the Z direction.

[0062] The first locking claw 66A is located above the second locking claw 66B. The first locking claw 66A is provided in the middle portion of the outer plate portion 64B in the Z direction. The first locking claw 66A is formed by cutting and raising a portion of the middle portion of the outer plate portion 64B in the X direction in the Y direction. The first locking claw 66A locks with the first locking surface 36A. The first locking claw 66A locks with one side (here, the upper side) of the movable housing 30 along the fitting direction. The first locking claw 66A is provided so that it can elastically deform and pass through the locking hole portion 36H1.

[0063] The second locking claw 66B is provided on the lower end of the outer plate portion 64B. The second locking claw 66B is formed by bending the entire lower end of the outer plate portion 64B in the Y direction. The second locking claw 66B locks with the second locking surface 36B. Note that there may or may not be a gap between the second locking claw 66B and the second locking surface 36B in the mating direction, as long as the second locking claw 66B faces the second locking surface 36B so as to be able to lock with the second locking surface 36B from the other side in the mating direction. The second locking claw 66B locks with the movable housing 30 on the other side in the mating direction (here, the lower side). For example, if the power terminal 60 is tilted in the X-axis direction (here, the left-right direction) with respect to the mating direction (here, the up-down direction), the second locking claw 66B abuts against the second locking surface 36B from below, preventing further tilting of the power terminal 60, thereby preventing excessive tilting of the power terminal 60. A portion of the power terminal holding portion 36 of the movable housing 30 is disposed between the first locking claw 66A and the second locking claw 66B.

[0064] The fixed housing 20 also supports the movable housing 30 from the other side (here, the lower side) along the mating direction. For example, the fixed housing 20 supports the movable housing 30 from below by abutting against the protrusion 39 of the movable housing 30 from below. The fixed housing 20 restricts downward movement of the movable housing 30.

[0065] As the power terminal 60 is inserted into the locking hole 36H1 from the tip of the tab terminal portion 65, the first locking claw 66A comes into contact with the peripheral edge of the lower opening of the locking hole 36H1 (here, the second locking surface 36B) and deforms, contracting. Once the first locking claw 66A passes through the locking hole 36H1, it resiliently returns to its original position and locks with the first locking surface 36A. Note that a gap between the first locking claw 66A and the first locking surface 36A in the mating direction may or may not exist, as long as the first locking claw 66A faces the first locking surface 36A so as to be able to lock with the first locking surface 36A. When the movable housing 30 moves upward relative to the first locking claw 66A, the first locking claw 66A abuts against the first locking surface 36A, thereby preventing further upward movement of the movable housing 30.

[0066] The power terminal 60 is held by the power terminal holding portion 36 so as to be movable along the X direction. When the movable housing 30 moves in the X direction, the connecting portion 67 of the power terminal 60 does not deform, and the second end 64 of the power terminal 60 does not move with the movable housing 30. When the movable housing 30 moves in the X direction, the power terminal 60 and the mating power terminal 90 can be connected while allowing for positional misalignment.

[0067] When the movable housing 30 moves in the Y direction, the connecting portion 67 of the power terminal 60 deforms, allowing the second end 64 to move with the movable housing 30. The connecting portion 67 of the power terminal 60 is also provided with an elastic portion 68. The elastic portion 68 extends in a trapezoidal wave shape in the mating direction, similar to the elastic portion 55. Furthermore, a slit 69 extending along the extension direction of the power terminal 60 is formed in the middle portion of the flat plate in the extension direction. This divides the flat plate in the middle portion of the extension direction of the power terminal 60 in the plate width direction. Here, two parallel slits 69 are formed in one flat plate, dividing it into three parts. Alternatively, one slit may be formed in one flat plate, dividing it into two parts. Alternatively, three or more parallel slits 69 may be formed in one flat plate, dividing it into four or more parts. The slit 69 is formed throughout the entire connecting portion 67 in the extension direction. The slit 69 also reaches a part of the first end 61 and a part of the second end 64 .

[0068] The dimension of the connecting portion 67 of the power terminal 60 along the Y direction is smaller than the dimension along the X direction. The dimension of the connecting portion 67 of the power terminal 60 along the X direction is the sum of the three sections divided by the slits 69, and is the plate width dimension. The dimension of the connecting portion 67 of the power terminal 60 along the Y direction is the plate thickness dimension. For this reason, the connecting portion 67 of the power terminal 60 is more likely to deform in the Y direction than in the X direction. Furthermore, here, the provision of the elastic portion 68 makes the connecting portion 67 of the power terminal 60 more likely to deform in the Y direction.

[0069] Before the floating connector 10 is connected to the mating connector 80, the movable housing 30 is positioned in an initial state. Here, in the initial state, the position of the movable housing 30 in the X and Y directions is, for example, a position where the center of the movable housing 30 coincides with the center of the peripheral wall 21 of the fixed housing 20. Also, in the initial state, the position of the movable housing 30 in the Z direction is, for example, a position where the lower part of the movable housing 30 is supported by the fixed housing 20. Such positioning is performed, for example, as follows.

[0070] The signal terminals 40 fit into the retaining holes 32H and the first retaining grooves 33G, thereby positioning the movable housing 30 in the X and Y directions. Furthermore, the power terminals 60 engage with the locking holes 36H1, thereby positioning the movable housing 30 in the Y and Z directions. Furthermore, the lower portion of the movable housing 30 is supported by the fixed housing 20, thereby positioning the movable housing 30 in the Z direction. In other words, the positioning of the movable housing 30 in the X direction is determined primarily by the signal terminals 40. Furthermore, the positioning of the movable housing 30 upward in the Z direction is determined primarily by the first locking claws 66A.

[0071] <Regarding the Mating Connector> The mating connector 80 will be described with further reference to Fig. 10. Fig. 10 is an exploded perspective view showing the mating connector 80 shown in Fig. 1.

[0072] The mating connector 80 has a mating housing 81, a plurality of mating signal terminals 85, and a plurality of mating power terminals 90. The mating signal terminals 85 are terminals for signal transmission. The mating power terminals 90 are terminals for power supply. The mating connector 80 is fixed to the board B2 with a fixture 87, similar to the floating connector 10. The mating housing 81 holds the plurality of mating terminals 85, 90 in the same arrangement as the plurality of terminals 40, 60. The mating housing 81 has a signal terminal holding portion 82 that holds the mating signal terminals 85, a power terminal holding portion 83 that holds the mating power terminals 90, and a guide portion 84 that contacts the guide receiver 38. A second holding groove 82G is formed in the signal terminal holding portion 82 of the mating housing 81. The signal terminal holding portion 31 of the movable housing 30 is mated with the signal terminal holding portion 82 of the mating connector 80, and the power terminals 60 of the floating connector 10 are mated with the mating power terminals 90 of the mating connector 80. Before these are fitted together, the guide receiving portion 38 and the guide portion 84 come into contact with each other, thereby correcting misalignment in the X and Y directions.

[0073] The guide portions 84 are provided on both ends of the movable housing 30 in the X direction. Two power terminal holding portions 83 are located between the two guide portions 84, and one signal terminal holding portion 82 is located between the two power terminal holding portions 83. The guide portions 84 are the parts that first come into contact with the floating connector 10 when the floating connector 10 and the mating connector 80, which are located apart from each other, approach each other in the mating direction. By providing the guide portions 84, any misalignment between the movable housing 30 of the floating connector 10 and the mating connector 80 in the X direction and Y direction is corrected before the terminals come into contact with each other.

[0074] The mating signal terminal 85 is press-fitted into the holding hole of the signal terminal holding portion 82. The mating signal terminal 85 has a spring-shaped portion 86.

[0075] The mating power terminal 90 has a spring-shaped portion 94 and is formed in a cylindrical shape into which the second end 64 of the power terminal 60 is inserted. The mating power terminal 90 is press-fitted into the holding hole 83H of the power terminal holding portion 83. The mating power terminal 90 has a board connecting portion 91, a cylindrical portion 92, a spring contact portion 95A, and a fixed contact portion 96. The board connecting portion 91 connects the mating power terminal 90 to the board B2. The cylindrical portion 92 surrounds the periphery of the power terminal 60. The cylindrical portion 92 is formed by bending the plate material that constitutes the mating power terminal 90 into a cylindrical shape. In this example, the cylindrical portion 92 is a rectangular cylindrical shape. The cylindrical portion 92 may have other rectangular cylindrical shapes, a cylindrical shape, or the like. The cylindrical portion 92 has a pair of wall portions 92X extending in the X direction and a pair of wall portions 92Y extending in the Y direction. Press-fit protrusions 93 are provided on the outer surfaces of the pair of wall portions 92Y for press-fitting into the power terminal holding portion 83. One of the pair of walls 92X is made up of two layers of overlapping plate material. Of the two layers of plate material, the one located on the inside of the tubular portion 92 is referred to as an inner plate portion 92X1, and the other located on the outside is referred to as an outer plate portion 92X2.

[0076] A portion of the inner plate portion 92X1 is cut and raised toward the inside of the cylindrical portion 92 to form a spring-shaped portion 94. The spring-shaped portion 94 is curved so that the intermediate portion in the Z direction is closest to the other of the pair of wall portions 92X. The plate portion constituting the spring-shaped portion 94 is curved so that the intermediate portion in the X direction (here, the center portion) is located more inward in the cylindrical portion 92 than both end portions in the X direction. The inner surface of the spring-shaped portion 94 is a curved surface that is curved when viewed from the fitting direction. A spring contact portion 95A is provided on the curved surface. The spring contact portion 95A is a portion that comes into contact with and is electrically connected to the power terminal 60. The portion of the curved surface that protrudes most inward of the cylindrical portion 92 is the spring contact portion 95A.

[0077] In the mating power supply terminal 90, of the pair of wall portions 92X, the wall portion 92X facing the spring-shaped portion 94 is provided with a convex fixed contact portion 96 that protrudes toward the spring-shaped portion 94. The spring contact portion 95A and the fixed contact portion 96 are provided at a distance from each other in the Y direction. Because the fixed contact portion 96 is a convex portion, the tab terminal portion 65 can be firmly clamped between the convex fixed contact portion 96 and the spring contact portion 95A.

[0078] Furthermore, in the mating power terminal 90, a cut-and-raised piece 97 may be formed on a portion of the outer plate portion 92X2 that faces a portion of the inner plate portion 92X1 that includes the spring contact portion 95A. When the power terminal 60 is not connected, the distance in the Y direction between the spring contact portion 95A and the fixed contact portion 96 is smaller than the thickness of the tab terminal 65 (here, the thickness of two overlapping plates). When the fixed contact portion 96 and the spring contact portion 95A clamp the tab terminal 65, the spring-shaped portion 94 bends toward the outer plate portion 92X2. At this time, the cut-and-raised piece 97 prevents the spring-shaped portion 94 from bending too far toward the outer plate portion 92X2.

[0079] <Mating Between Floating Connector and Mating Connector> When connecting the floating connector 10 and the mating connector 80, the worker moves the floating connector 10 and the mating connector 80 relative to each other in the mating direction. Here, the boards B1 and B2 are moved relative to each other in the mating direction.

[0080] When the floating connector 10 and the mating connector 80 approach each other, if there is no misalignment in the X and Y directions between the floating connector 10 and the mating connector 80, the signal terminal holding portions 31, 82 will fit together as they are, and the power terminal holding portions 36, 83 will fit together, without the movable housing 30 moving. As a result, the signal terminals 40, 85 will be electrically connected to each other, and the power terminals 60, 90 will be electrically connected to each other.

[0081] When the floating connector 10 and the mating connector 80 approach each other, if there is a misalignment between the floating connector 10 and the mating connector 80 in the X or Y direction, the guide portion 84 of the mating connector 80 contacts and is guided by the guide receiving portion 38 of the floating connector 10, and the movable housing 30 moves in the direction of the misalignment. Here, one side of one guide portion 84 facing outward in the X direction and two side surfaces facing outward in the Y direction each have a guide surface inclined with respect to the Z direction at their respective tips. The guide surfaces facing outward in the X direction of the two guide portions 84 form a pair of guide surfaces in the X direction. Furthermore, the guide surfaces facing outward in the Y direction of the two guide portions 84 form two pairs of guide surfaces in the Y direction. Below, the correction of misalignment in the X and Y directions will be described in more detail. If there is a misalignment between the floating connector 10 and the mating connector 80 in both the X and Y directions, the misalignment in both the X and Y directions is corrected.

[0082] <Regarding correction of misalignment in the X direction> When the floating connector 10 and the mating connector 80 are misaligned in the X direction, one of a pair of guide surfaces in the X direction of the mating connector 80 comes into contact with the tip of one of the pair of wall portions 37Y of the movable housing 30. As a result, the movable housing 30 receives a force in the X direction from the mating connector 80, and the movable housing 30 moves in the X direction.

[0083] When the movable housing 30 moves in the X direction due to the force from the guide portion 84, the second end 48 of the signal terminal 40 receives the force from the movable housing 30 at the contact surface with the movable housing 30. This causes the elastic portion 55 of the signal terminal 40 to elastically deform, and the second end 48 of the signal terminal 40 moves following the movable housing 30.

[0084] Meanwhile, the movable housing 30 is also movable in the X direction relative to a portion of the power terminal 60 that includes the second end 64. Here, the dimension of the locking hole 36H1 in the X direction is larger than the dimension of the held portion 66. Even if the movable housing 30 moves in the X direction, the second end 64 of the power terminal 60 is not in contact with the movable housing 30 and is therefore not subjected to force from the movable housing 30. Therefore, although the power terminal holding portion 36 of the movable housing 30 moves in the X direction, the second end 64 of the power terminal 60 does not move.

[0085] More specifically, as shown in FIG. 6 , the power terminal 60 includes a pair of first outer surfaces 64A facing opposite each other in the X direction. The movable housing 30 includes a pair of first inner surfaces 36C covering the pair of first outer surfaces 64A, respectively. For example, in the X direction, the inner surfaces of the retaining holes 36H of the movable housing 30 are the first inner surfaces 36C, and the outer surfaces of the portions of the power terminal 60 that fit into the retaining holes 36H are the first outer surfaces 64A. In the initial state, the opposing surfaces of the pair of first outer surfaces 64A and the pair of first inner surfaces 36C are spaced apart from each other. The distance DX1 shown in FIG. 6 is the distance between the opposing first outer surfaces 64A and first inner surfaces 36C in the initial state.

[0086] As shown in FIG. 6 , the movable housing 30 includes a pair of second outer surfaces 37YA facing opposite each other along the X direction. The fixed housing 20 includes a pair of second inner surfaces 21YA covering the pair of second outer surfaces 37YA, respectively. For example, the second outer surfaces 37YA are outer surfaces of the wall portion 37Y, and the second inner surfaces 21YA are inner surfaces of the wall portion 21Y. In the initial state, opposing surfaces of the pair of second outer surfaces 37YA and the pair of second inner surfaces 21YA are spaced apart from each other. The distance DX2 shown in FIG. 6 is the distance between the opposing second outer surfaces 37YA and second inner surfaces 21YA in the initial state.

[0087] The distance DX2 is, for example, the amount of movement of the movable housing 30 on one side in the X direction relative to the fixed housing 20. Even at the other end in the X direction (not shown), the outer surface of the wall 37Y of the movable housing 30 faces the inner surface of the wall 21Y of the fixed housing 20 across the distance DX2. In the initial state, the movable housing 30 can move by the distance DX2 on both sides in the X direction.

[0088] 6 is the distance between the inner surfaces of the pair of wall portions 92Y of the tubular portion 92. The distance DX3 is approximately equal to the sum of the dimension of the tab terminal portion 65 in the X direction and twice the dimension of the distance DX1. For example, if there is a small clearance between the movable housing 30 and the mating housing 81 in the X direction, the distance DX3 may be slightly smaller than the sum of the dimension of the tab terminal portion 65 in the X direction and twice the dimension of the distance DX1 by the amount of the clearance. This clearance may be equal to or smaller than one-tenth of the distance DX1.

[0089] In this embodiment, the distance DX1 is the same as the distance DX2. This allows the movable housing 30 to move relative to the power terminal 60 in the X direction by the same amount as the movable amount of the movable housing 30 relative to the fixed housing 20. As a result, when the movable housing 30 moves in the X direction relative to the fixed housing 20, the amount of movement of the second end 64 of the power terminal 60 is substantially zero. This means that the second end 64 of the power terminal 60 does not need to deform in the X direction so as to follow the movable housing 30. This allows for a reduction in the mating force.

[0090] The spring contact portion 95A of the mating power terminal 90 and the tab terminal portion 65 of the power terminal 60 are in point-to-surface contact (point-surface contact). Here, when misalignment in the X direction is corrected, the position of the tab terminal portion 65 of the power terminal 60 along the X direction within the tubular portion 92 of the mating power terminal 90 may change. In this case, regardless of the position of the tab terminal portion 65 along the X direction within the tubular portion 92, approximately the same portion of the spring contact portion 95A contacts the tab terminal portion 65 of the power terminal 60. On the other hand, when misalignment in the X direction is corrected, the portion of the tab terminal portion 65 that contacts the spring contact portion 95A may change.

[0091] As described above, if there is misalignment between the floating connector 10 and the mating connector 80 in the X direction, the movable housing 30 and the second ends 48 of the signal terminals 40 move to correct the misalignment. The second ends 64 of the power terminals 60 do not move, and are connected to the mating power terminals 90 while allowing for misalignment.

[0092] <Regarding Correction of Positional Misalignment in the Y Direction> When the floating connector 10 and the mating connector 80 are misaligned in the Y direction, of the two pairs of guide surfaces in the Y direction of the mating connector 80, the two guide surfaces on one side along the Y direction come into contact with the tip of one of the pair of wall portions 37X of the movable housing 30. As a result, the movable housing 30 receives a force in the Y direction from the mating connector 80. As a result, the movable housing 30 moves in the Y direction relative to the fixed housing 20.

[0093] When the movable housing 30 moves in the Y direction due to the force from the guide portion 84, the second ends 48 of the signal terminals 40 and the second ends 64 of the power terminals 60 receive a force from the movable housing 30 at their contact surfaces with the movable housing 30. For example, when the movable housing 30 moves right from the state shown in FIG. 4 , the left and right power terminals 60 each receive a rightward force from the inner surfaces of the locking holes 36H1 that face right in the Y direction. Similarly, when the movable housing 30 moves right from the state shown in FIG. 5 , the right signal terminal 40 receives a rightward force from the inner surface 32B and the bottom surface of the first retaining groove 33G. The left signal terminal 40 receives a rightward force from the inner surface 32A. As a result, the elastic portions 55 of the signal terminals 40 and the elastic portions 68 of the power terminals 60 elastically deform, causing the second ends 48 of the signal terminals 40 and the second ends 64 of the power terminals 60 to move in accordance with the movable housing 30. This corrects the positional deviation between the floating connector 10 and the mating connector 80 along the Y direction.

[0094] If there is misalignment in the X or Y direction between the floating connector 10 and the mating connector 80, the misalignment is corrected as described above. When the floating connector 10 and the mating connector 80 move closer in the mating direction after the misalignment in the X and Y directions has been corrected, the signal terminal holding portions 31, 82 mate with each other, and the power terminal holding portions 36, 83 mate with each other. As a result, the signal terminals 40, 85 are electrically connected to each other, and the power terminals 60, 90 are electrically connected to each other.

[0095] The spring-shaped portion 86 of the mating signal terminal 85 comes into contact between the first spring-shaped portion 50 and the second held portion 51 of the signal terminal 40. The distance between the first spring-shaped portion 50 and the second held portion 51 of the signal terminal 40 is longer than the length of the spring-shaped portion 86 of the mating signal terminal 85. If the positions of the boards B1 and B2 are misaligned in the Z direction, the position at which the spring-shaped portion 86 of the mating signal terminal 85 comes into contact with the signal terminal 40 along the Z direction changes. In addition, the tab terminal portion 65 of the power terminal 60 extends linearly. The insertion amount of the tab terminal portion 65 of the power terminal 60 into the tubular portion 92 of the mating power terminal 90 is changeable. If the positions of the boards B1 and B2 are misaligned in the Z direction, the insertion amount of the power terminal 60 into the mating power terminal 90 changes. As a result, misalignment in the Z direction is also absorbed.

[0096] <Regarding the Signal Terminal 40 and the Mating Signal Terminal 85> The signal terminal 40, the mating signal terminal 85, and their surrounding structures will be described with further reference to FIGS. 11 to 15. FIG. 11 is an explanatory diagram showing the mated state of the signal terminal 40 and the mating signal terminal 85 according to the first embodiment. Note that FIG. 11 illustrates a mated state without misalignment. FIG. 12 is an explanatory diagram showing the state immediately before mating of the signal terminal 40 and the mating signal terminal 85 according to the first embodiment. Note that in FIGS. 11 and 12, the signal terminal 40 and the mating signal terminal 85 on the right side of the page are shown in phantom lines. FIG. 13 is an end view taken along line XIII-XIII in FIG. 12. FIG. 14 is an explanatory diagram showing the dimensions of the signal terminal 40 and the mating signal terminal 85. In FIG. 14, the signal terminal 40 and the mating signal terminal 85 indicated by solid lines are shown in front view. In addition, in Fig. 14, the signal terminal 40 and the mating signal terminal 85 shown by phantom lines are the signal terminal 40 and the mating signal terminal 85 extracted from the left side of the paper in Fig. 11. Fig. 15 is an explanatory diagram showing the signal terminal 40 and the holding portion for the signal terminal 40. In Fig. 15, only one signal terminal 40 is shown.

[0097] The signal terminal 40 has the first terminal portion 49 and a first connecting plate portion 49A continuing to the first terminal portion 49 along the mating direction (Z direction). The mating signal terminal 85 has a second terminal portion 85C extending in the mating direction (Z direction) and a second connecting plate portion 85D continuing to the second terminal portion 85C along the mating direction (Z direction). The first terminal portion 49 and the second terminal portion 85C form a parallel plate portion P aligned in the first direction (Y direction). The first connecting plate portion 49A and the second connecting plate portion 85D extend in opposite directions from the parallel plate portion P.

[0098] As shown in Figure 14, the first terminal portion 49 has a first base plate portion 49B extending in the mating direction and a first spring contact portion 50A provided further distally than the first base plate portion 49B. The second terminal portion 85C has a second base plate portion 85E extending in the mating direction and a second spring contact portion 86A provided further distally than the second base plate portion 85E. As shown by the imaginary lines in Figure 14, the first base plate portion 49B and the second base plate portion 85E are spaced apart from each other in the first direction (Y direction). The first spring contact portion 50A contacts the second base plate portion 85E. The second spring contact portion 86A contacts the first base plate portion 49B.

[0099] The mating signal terminal 85 also has a board connecting portion 85A and a held portion 85B held by the signal terminal holding portion 82. A press-fit protrusion 85B1 is formed in the held portion 85B. The signal terminal holding portion 82 also has holding holes aligned in the Y direction. Like the holding hole 23H, the holding hole of the signal terminal holding portion 82 also has a plurality of first hole portions through which the plurality of mating signal terminals 85 are individually passed and a single second hole portion that communicates with the plurality of first hole portions and through which the plurality of mating signal terminals aligned in the X direction are collectively passed. Of the two press-fit protrusions 85B1, the press-fit protrusion 85B1 on the second terminal portion 85C side is press-fitted into the first hole portion. Of the two press-fit protrusions 85B1, the press-fit protrusion 85B1 on the board connecting portion 85A side is press-fitted into the second hole portion.

[0100] 12 , in the first direction (Y direction), the first spring contact portion 50A protrudes outward beyond the tip surface of the side wall 33W of the first retaining groove 33G. Also, in the first direction (Y direction), the second spring contact portion 86A protrudes outward beyond the tip surface of the side wall 82W of the second retaining groove 82G. The tip surface of the side wall 33W of the first retaining groove 33G and the tip surface of the side wall 82W of the second retaining groove 82G face each other with a gap between them.

[0101] The first retaining groove 33G has a first base plate portion groove portion 33G1 corresponding to the first base plate portion 49B and a first spring-shaped portion groove portion 33G2 corresponding to the first spring-shaped portion 50. The bottom surface of the first base plate portion groove portion 33G1 overlaps with the first base plate portion 49B in the first direction (Y direction). The bottom surface of the first spring-shaped portion groove portion 33G2 overlaps with the first spring-shaped portion 50 in the first direction. The second retaining groove 82G has a second base plate portion groove portion 82G1 corresponding to the second base plate portion 85E and a second spring-shaped portion groove portion 82G2 corresponding to the second spring-shaped portion 86. The bottom surface of the second base plate portion groove portion 82G1 overlaps with the second base plate portion 85E in the first direction. The bottom surface of the second spring-shaped portion groove portion 82G2 overlaps with the second spring-shaped portion 86 in the first direction.

[0102] As shown by the solid lines in FIG. 14 , the dimension of the first terminal 49 is smaller than the dimension of the first connecting plate 49A in the second direction (X direction). Furthermore, the dimension of the second terminal 85C is smaller than the dimension of the second connecting plate 85D in the second direction (X direction). The second base plate 85E is provided with a restricting portion 85F to restrict tilting of the second terminal 85C within the second retaining groove 82G. The restricting portion 85F is thicker than the rest of the second base plate 85E and is approximately the same thickness as the second connecting plate 85D. However, because the restricting portion 85F is provided only on a portion of the second terminal 85C, it is unlikely to significantly impede impedance adjustment. For example, the length of the restricting portion 85F in the mating direction may be 10 percent or less of the length of the second terminal 85C.

[0103] In FIG. 13 , dimension H1 is the height dimension of the side wall 33W1 from the bottom surface 33B1 of the first base plate portion groove portion 33G1. Dimension H1 corresponds to the dimension of the side wall 33W of the first holding groove 33G in the first direction (Y direction). Dimension H2 is the thickness dimension of the first base plate portion 49B. Dimension H2 corresponds to the dimension of the first terminal portion 49 in the first direction (Y direction). As shown in FIG. 13 , dimension H1 of the side wall 33W of the first holding groove 33G in the first direction (Y direction) is smaller than dimension H2 of the first terminal portion 49. For example, dimension H1 of the side wall 33W of the first holding groove 33G may be smaller than dimension H2 of the first terminal portion 49 and greater than half of dimension H2 of the first terminal portion 49.

[0104] In addition, in FIG. 13 , dimension H3 is the height dimension of the side wall 82W1 from the bottom surface 82B1 of the second base plate portion groove portion 82G1. Dimension H3 corresponds to the dimension of the side wall 82W of the second holding groove 82G in the first direction (Y direction). Dimension H4 is the thickness dimension of the second base plate portion 85E. Dimension H4 corresponds to the dimension of the second terminal portion 85C in the first direction (Y direction). As shown in FIG. 13 , dimension H3 of the side wall 82W of the second holding groove 82G in the first direction (Y direction) is smaller than dimension H4 of the second terminal portion 85C. For example, dimension H3 of the side wall 82W of the second holding groove 82G may be smaller than dimension H4 of the second terminal portion 85C and greater than half of dimension H4 of the second terminal portion 85C.

[0105] 12 , the depth of the first spring-shaped portion groove portion 33G2 is deeper than the depth of the first base plate portion groove portion 33G1 in the first direction. The positions of the tip of the side wall 33W2 and the bottom surface 33B2 of the first spring-shaped portion groove portion 33G2 are shifted inward in the Y direction relative to the tip of the side wall 33W1 and the bottom surface 33B1 of the first base plate portion groove portion 33G1, but the amount of change in the bottom surface 33B1, 33B2 is greater than the amount of change in the tips of the side walls 33W1, 33W2. The depth of the second spring-shaped portion groove portion 82G2 is deeper than the depth of the second base plate portion groove portion 82G1. Although the positions of the tip of the side wall 82W2 and the bottom surface 82B2 of the second spring-shaped portion groove portion 82G2 are shifted outward in the Y direction from the positions of the tip of the side wall 82W1 and the bottom surface 82B2 of the second base plate portion groove portion 82G1, the amount of change in the bottom surfaces 82B1, 82B2 is greater than the amount of change in the tips of the side walls 82W1, 82W2. Note that the tip of the side wall 33W2 of the first spring-shaped portion groove portion 33G2 is at the same level as or higher than the bottom surface 33B1 of the first base plate portion groove portion 33G1.

[0106] The signal terminal 40 has a third connecting plate portion 44A that is continuous with the portion of the first held portion 44 where the press-fit protrusion 45 is provided. As shown in Fig. 14, the dimension of the third connecting plate portion 44A in the second direction (Y direction) is smaller than the dimension of the first connecting plate portion 49A. Here, the third connecting plate portion 44A is located on both sides of the portion of the first held portion 44 where the press-fit protrusion 45 is provided. The third connecting plate portion 44A may be located on only one side of the portion of the first held portion 44 where the press-fit protrusion 45 is provided.

[0107] The third connecting plate portion 44A has a first portion 44B and a second portion 44C that differ in size in the second direction. The first portion 44B is thinner than the second portion 44C. The first portion 44B has a smaller size in the second direction than the second portion 44C. The first portion 44B and the second portion 44C are each continuous with each other in the mating direction (Z direction) with a constant plate width. The first portion 44B and the second portion 44C may each have a portion extending in the mating direction (Z direction) with a varying plate width connected to both ends thereof. The first portion 44B is located between the portion of the first held portion 44 where the press-fit protrusion 45 is provided and the second portion 44C. The first portion 44B and the second portion 44C are located on either side of the portion of the first held portion 44 where the press-fit protrusion 45 is provided.

[0108] <Effects, etc.> With the connector device 100 configured as described above, impedance may vary between the portion of the signal terminal 40 and the mating signal terminal 85 that forms the parallel plate portion P and the portion that does not form the parallel plate portion P. By making the dimension of the first terminal portion 49 that forms the parallel plate portion P smaller than the dimension of the first connecting plate portion 49A that does not form the parallel plate portion P in the second direction, and by making the dimension of the second terminal portion 85C that forms the parallel plate portion P smaller than the dimension of the second connecting plate portion 85D that does not form the parallel plate portion P, impedance mismatch can be suppressed. Therefore, good communication performance can be achieved with the connector device 100. Specifically, by reducing the cross-sectional area of ​​the signal terminal 40 and the mating signal terminal 85 in the parallel plate portion P, the resistance of the signal terminal 40 and the mating signal terminal 85 can be increased, and a decrease in impedance can be suppressed.

[0109] Furthermore, in the first direction (Y direction), the dimension H1 of the sidewall 33W of the first retaining groove 33G is smaller than the dimension H2 of the first terminal portion 49, and the dimension H3 of the sidewall 82W of the second retaining groove 82G is smaller than the dimension H4 of the second terminal portion 85C. This makes it easier to suppress impedance mismatch in the parallel plate portion P. Specifically, the impedance of a terminal is more likely to be higher when it is covered with an air layer than when it is covered with a resin layer. Therefore, by covering the portions of the signal terminal 40 and the mating signal terminal 85 where the impedance is reduced with an air layer as much as possible, the reduction in impedance can be suppressed.

[0110] Furthermore, because dimension H1 is smaller than dimension H2 and dimension H3 is smaller than dimension H4, it is possible to prevent the first terminal portion 49 from climbing up onto the side wall 82W of the second retaining groove 82G and the second terminal portion 85C from climbing up onto the side wall 33W of the first retaining groove 33G. Specifically, when the second spring contact portion 86A contacts the first base plate portion 49B, the second spring contact portion 86A and the first base plate portion 49B may be displaced in the plate width direction (X direction) as shown in FIG. 13 . Even in this case, because the first base plate portion 49B protrudes toward the mating signal terminal 85 beyond the side wall 33W1, the second spring contact portion 86A is prevented from climbing up onto the side wall 33W1. Similarly, because the second base plate portion 85E protrudes toward the signal terminal 40 beyond the side wall 82W1, it is possible to prevent the first spring contact portion 50A from climbing up onto the side wall 82W1. This allows the first base plate portion 49B and the second spring contact portion 86A to contact more reliably, and also allows the second base plate portion 85E and the first spring contact portion 50A to contact more reliably.

[0111] Furthermore, the first spring contact portion 50A contacts the second base plate portion 85E, and the second spring contact portion 86A contacts the first base plate portion 49B. Thus, by providing two contact portions 50A, 86A, the connection reliability between the signal terminal 40 and the mating signal terminal 85 is improved. In this case, the parallel plate portion P can provide a conductive path for both the first terminal portion 49 and the second terminal portion 85C. Therefore, if the plate widths of the first terminal portion 49 and the second terminal portion 85C in the parallel plate portion P are made the same as the plate widths of the first connecting plate portion 49A and the second connecting plate portion 85D, the apparent conductor cross-sectional area in the parallel plate portion P will be larger than the conductor cross-sectional areas of the first connecting plate portion 49A and the second connecting plate portion 85D, which will likely result in a decrease in impedance. Here, by making the plate width of the first terminal portion 49 and the second terminal portion 85C smaller than the plate width of the first connecting plate portion 49A and the second connecting plate portion 85D in the parallel plate portion P, the apparent conductor cross-sectional area in the parallel plate portion P is prevented from becoming larger than the conductor cross-sectional area of ​​each of the first connecting plate portion 49A and the second connecting plate portion 85D, thereby suppressing a decrease in impedance.

[0112] In addition, in the first direction, the first spring contact portion 50A protrudes outward beyond the tip surface of the side wall 33W of the first retaining groove 33G, and the second spring contact portion 86A protrudes outward beyond the tip surface of the side wall 82W of the second retaining groove 82G. This eliminates the need for walls covering the sides of the spring contact portions 50A, 86A, making it easier to suppress impedance mismatching at the spring contact portions 50A, 86A. As described above, by covering the portions of the signal terminal 40 and the mating signal terminal 85 where impedance drops with as much air as possible, the drop in impedance can be suppressed.

[0113] Furthermore, the spring contact portions 50A, 86A come into contact with each other when the signal terminal 40 and the mating signal terminal 85 are mated. In the first direction, the depth of the first spring-shaped portion groove portion 33G2 is deeper than the depth of the first base plate portion groove portion 33G1, and the depth of the second spring-shaped portion groove portion 82G2 is deeper than the depth of the second base plate portion groove portion 82G1. This allows the spring contact portions 50A, 86A to contact each other during mating, thereby allowing the spring contact portions 50A, 86A to escape deflection of the spring contact portions 50, 86A. That is, during mating, contact with the bottom surface of the first retaining groove 33G can be prevented from becoming difficult to deflect, and similarly, during mating, contact with the bottom surface of the second retaining groove 82G can be prevented from becoming difficult to deflect, and similarly, during mating, contact with the bottom surface of the second retaining groove 82G can be prevented from becoming difficult to deflect. Furthermore, the space between the spring contact portion 50A, 86A and the groove bottom surface 33B2, 82B2 can be increased, which makes it easier to suppress impedance mismatch at the spring contact portion 50A, 86A. As described above, by covering the portions of the signal terminal 40 and the mating signal terminal 85 where impedance drops with as much air as possible, the drop in impedance can be suppressed.

[0114] Furthermore, the dimension of the third connecting plate portion 44A in the second direction (X direction) is smaller than the dimension of the first connecting plate portion 49A. The portion provided with the press-fit protrusion 45 is press-fit into the resin wall, and the impedance is likely to change. By reducing the plate width of the third connecting plate portion 44A connected to the first held portion 44, it is easy to suppress impedance mismatch around the first held portion 44.

[0115] The third connecting plate 44A has a first portion 44B and a second portion 44C that are different in size in the second direction (X direction). This makes it easier to prevent misalignment around the first held portion 44.

[0116] Furthermore, the connector 10 is a floating connector 10. This makes it possible to suppress impedance mismatching of the signal terminals 40 in the floating connector 10, and good communication performance can be obtained in the connector device 100 including the floating connector 10.

[0117] [Additional Notes] In the first embodiment, the connector 10 is described as being a floating connector 10, but this is not a required configuration. The connector 10 may be a connector that is not a floating connector, such as the mating connector 80.

[0118] The configurations described in the above embodiments and modifications can be combined as appropriate as long as they are not mutually contradictory.
