[Description of the embodiments of the present disclosure]
First, the embodiments of the present disclosure will be listed and described.

The floating connector disclosed herein is as follows:

(1) A floating connector comprising a fixed housing, a movable housing movably provided relative to the fixed housing, and a signal terminal bridged between the fixed housing and the movable housing, the signal terminal including a first end held by the fixed housing, a second end held by the movable housing, and a connecting portion connecting the first end and the second end, the connecting portion elastically deforms when the movable housing moves, and the second end is capable of following the movable housing, and the second end is held by the movable housing with a holding force weaker than the holding force of the first end.

In the floating connector of (1), if the second end is held by the movable housing with a holding force equal to or greater than the holding force of the first end, a large stress may be applied to the elastically deformed portion of the connecting portion when the movable housing moves. In this case, measures such as lengthening the length of the connecting portion are required to distribute the stress. In the present disclosure, since the second end is held by the movable housing with a holding force weaker than the holding force of the first end, it is possible to prevent a large stress from being applied to the elastically deformed portion of the connecting portion when the second end moves following the movable housing. This prevents the length of the connecting portion from becoming longer, thereby preventing adverse effects on communication performance. This allows the floating connector to achieve good communication performance.

(2) In the floating connector of (1), the first end may be provided with a press-fit protrusion that is press-fitted into the fixed housing, the movable housing may be formed with a retaining hole through which the signal terminal passes, and the second end may be held in the retaining hole so as to be movable along the longitudinal direction of the signal terminal. As a result, when stress is applied to the signal terminal, stress is less likely to concentrate at a specific portion of the second end because the second end is movable relative to the retaining hole. This further reduces the need to increase the length of the signal terminal to distribute stress.

(3) In the floating connector of (2), the distance between the first and second inner faces of the retaining hole, which face in opposite directions along the thickness direction of the signal terminal, may be greater than the thickness of the signal terminal, and the second end may be in contact with both the first and second inner faces while bending in the thickness direction. This makes it easier for the second end to follow the movable housing when the movable housing moves to either one side or the other side along the thickness direction of the signal terminal.

(4) In the floating connector of (2) or (3), the fixed housing may also be formed with a retaining hole through which the signal terminal passes, and the retaining hole of the movable housing may be positioned on an extension line of the retaining hole of the fixed housing. This makes it easier to pass the signal terminal through the retaining hole of the fixed housing and the retaining hole of the movable housing. In addition, the width dimension of the floating connector can be reduced.

(5) In any one of the floating connectors (1) to (4), the first end may be provided with a press-fit protrusion that is press-fitted into the fixed housing, and the second end may not be provided with a press-fit protrusion that is press-fitted into the movable housing. This allows configurations with different holding forces to be provided with a simple structure.

(6) In any one of the floating connectors (1) to (5), the signal terminal may have a first extension portion extending linearly and a second extension portion extending linearly in a direction intersecting the first extension portion, and the first extension portion and the second extension portion may be connected via multiple bends that bend in the same direction. One of the factors that can deteriorate communication performance is attenuation due to reflection at the bends. In the present disclosure, the first extension portion and the second extension portion are connected via multiple bends that bend in the same direction, so that the bending angle of each of the multiple bends is gentle. This makes it easier for the reflected wave at the bends to proceed in the traveling direction. This makes it less likely that attenuation due to reflection at the bends will occur, and deterioration of communication performance can be suppressed.

(7) In any one of the floating connectors (1) to (6), the first end and the second end may be spaced apart from each other along the mating direction with the mating connector, and the connecting portion may be provided with an elastic portion that extends in a trapezoidal wave shape from the first end to the second end along the mating direction. By providing the elastic portion, the elastic portion is more likely to elastically deform when the second end follows the movable housing. In addition, since the elastic portion extends in a trapezoidal wave shape from the first end to the second end, the width dimension of the floating connector can be made smaller than when the elastic portion is formed in a multi-step staircase shape or a U-shape that reciprocates along the mating direction.

(8) In any one of the floating connectors (1) to (6), the connecting portion may extend linearly from the first end to the second end. This makes it easier to shorten the length of the signal terminal.

(9) In any one of the floating connectors (1) to (8), the floating connector may include a power terminal that is bridged between the fixed housing and the movable housing, and the power terminal may have a conductor cross-sectional area larger than the conductor cross-sectional area of the signal terminal and may be held in a press-fit state in the movable housing. This allows the movable housing to be firmly supported via the power terminal.

[Details of the embodiment of the present disclosure]
Specific examples of the floating connector 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.

[Embodiment 1]
The floating connector according to the first embodiment will be described below. Fig. 1 is a perspective view showing a floating connector 10 according to the first embodiment and a connector device 100 including the same. Fig. 2 is an exploded perspective view showing the connector device 100. Fig. 3 is an exploded front view showing the connector device 100. Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 3. Fig. 5 is a cross-sectional view taken along line V-V in Fig. 3. Fig. 6 is an exploded perspective view showing the floating connector 10. Fig. 7 is a perspective view showing a signal terminal 40. Fig. 8 is a perspective view showing a power terminal 60. In each figure, mutually orthogonal X, Y, and Z directions are shown.

In the present disclosure, the connector device 100 includes a floating connector 10 and a mating connector 90 that fits into the floating connector 10. As shown in FIG. 3 and other figures, in this embodiment, the floating connector 10 and the mating connector 90 are described as board connectors that are electrically connected to boards B1 and B2, respectively. When the floating connector 10 and the mating connector 90 are fitted together, the terminals of the floating connector 10 and the terminals of the mating connector 90 are electrically connected. As a result, the boards B1 and B2 to which the floating connector 10 and the mating connector 90 are connected are electrically connected to each other. The floating connector 10 and the mating connector 90 may be connectors other than board connectors.

The floating connector 10 and the mating connector 90 are mated by moving toward each other along the mating direction. In this embodiment, the mating direction is a direction perpendicular to the main surfaces of the boards B1 and B2, and is shown as the Z direction in each figure. 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. Below, the X direction may be referred to as the front-back direction, the Y direction as the left-right direction, and the Z direction as the up-down direction. Note that the mating direction of the floating connector 10 and the mating connector 90 may be a direction other than the Z direction.

The floating connector 10 comprises a fixed housing 20, a movable housing 30, a plurality of signal terminals 40, and a plurality of power terminals 60. The fixed housing 20 is fixed to the board B1 via a fixture 80. 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 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.

In this embodiment, the signal terminals 40 and the 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 (here, 80), and the number of parallel signal terminals 40 in the Y direction is 2. 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 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 appropriately. As in the example of the embodiment, it is preferable that the number of parallel signal terminals 40 in the X direction is greater than the number of parallel signal terminals 40 in the Y direction.

The orientations of a pair of adjacent signal terminals 40 along the X direction are in the same direction. The orientations of a pair of adjacent signal terminals 40 along the Y direction are in opposite directions. Similarly, the orientations of a pair of adjacent power terminals 60 along the X direction are in the same direction, and the orientations of a pair of adjacent power terminals 60 along the Y direction are in opposite directions.

The fixed housing 20 is molded using an electrically insulating material such as synthetic resin. The fixed housing 20 is formed in a cylindrical shape with openings at the top and bottom. 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 a peripheral wall 21 that covers the periphery of the opening. The lower part of the movable housing 30 is disposed in the internal space of the peripheral wall 21. The upper part of the movable housing 30 protrudes upward from the upper opening of the fixed housing 20. In the X direction and the Y direction, the inner surface of the peripheral wall 21 and the outer surface of the movable housing 30 face each other with a gap therebetween. The fixed housing 20 includes a signal terminal holding portion 22, a power terminal holding portion 24, a first cover portion 26, and a fixture holding portion 29.

The signal terminal holding portion 22 is a portion that holds the first end 42 of the signal terminal 40. The signal terminal holding portion 22 has a pair of holding bodies 23 formed in the shape of a rectangular block. Each holding body 23 protrudes from the inner surface of each wall portion 21X toward the internal space of the peripheral wall 21. Each holding body 23 is provided at the middle portion of each wall portion 21X along the X direction and at the lower portion along the Z direction. The pair of holding bodies 23 are aligned at intervals along the Y direction. Each holding body 23 is formed with a first holding hole 23H that penetrates in the Z direction.

The first retaining hole 23H has a plurality of first hole portions 23H1 and one second hole portion 23H2. In one retaining body 23, the multiple first hole portions 23H1 are aligned in the X direction. Multiple signal terminals 40 aligned in the X direction are individually passed through the multiple first hole portions 23H1. One second hole portion 23H2 is located below the multiple first hole portions 23H1. The multiple first hole portions 23H1 and the one second hole portion 23H2 are continuous along the Z direction. Multiple signal terminals 40 aligned in the X direction are collectively passed through the one second hole portion 23H2.

The power terminal holding portion 24 is a portion that holds the first end 42 of the power terminal 60. The power terminal holding portion 24 has two pairs of holding bodies 25 formed in the shape of a rectangular block. Each holding body 25 protrudes from the inner surface of each wall portion 21X toward the internal space of the peripheral wall 21. The holding body 23 of the signal terminal holding portion 22 is located between the first pair of holding bodies 25 and the second pair of holding bodies 25. Each holding body 25 is provided on the lower part along the Z direction of each wall portion 21X. Each pair of holding bodies 25 is lined up at intervals along the Y direction. Two recesses 25A are formed in each holding body 25. Each recess 25A is formed from the lower surface of the holding body 25 to the inner surface facing inward along the Y direction. Each recess 25A individually fits a power terminal 60.

The first cover portion 26 covers the middle portion of the signal terminal 40 from the outside in the Y direction. In this embodiment, the first cover portion 26 is the upper portion of the wall portion 21X where the holding body 23 is formed. The inner surface of the first cover portion 26 is the first slope portion 27. The first slope portion 27 continues from the upper surface of the holding body 23 to the upper surface of the wall portion 21X. The entire inner surface of the first cover portion 26 is the first slope portion 27.

The fixture holding portion 29 is a portion that holds the fixture 80. The fixture holding portion 29 is formed on the outer surface of the wall portion 21Y. The fixture holding portion 29 is formed in a slot shape into which the fixture 80 can be inserted from above.

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 holding portion 31, a power terminal holding portion 34, a second cover portion 36, and a guide portion 39.

The signal terminal holding portion 31 is a portion that holds the second end 48 of the signal terminal 40. The signal terminal holding portion 31 includes a base portion 32 and a rib 33. The base portion 32 is located between a pair of signal terminals 40 arranged in the Y direction. The rib 33 protrudes outward in the Y direction from the lower portion of the base portion 32. A plurality of holding grooves 32G are formed on the outer surface of the upper portion of the base portion 32 that faces outward in the Y direction. A plurality of second holding holes 33H are formed in the rib 33. The plurality of holding grooves 32G and the plurality of second holding holes 33H are provided in the same number and correspond one-to-one. Each holding groove 32G and each second holding hole 33H are continuous in the Z direction. The lower portions of the second end portions 48 of the plurality of signal terminals 40 are individually passed through the plurality of second holding holes 33H. The upper portions of the second end portions 48 of the plurality of signal terminals 40 are individually accommodated in the plurality of holding grooves 32G.

The power terminal holding portion 34 holds the second end 64 of the power terminal 60. The power terminal holding portion 34 has two holding bodies 35 formed in the shape of a rectangular parallelepiped block. The signal terminal holding portion 31 is disposed between the two holding bodies 35. A plurality of holding holes 35H are formed in each holding body 35. A plurality of power terminals 60 are individually passed through the plurality of holding holes 35H.

The second cover portion 36 protrudes downward from the lower portion of the base portion 32. A second inclined surface portion 37 is provided on the outer surface of the second cover portion 36 facing the Y direction. The upper portion of the second inclined surface portion 37 is continuous with the lower surface of the rib 33.

The guide portions 39 are provided on both ends of the movable housing 30 along the X direction. Two power terminal holding portions 34 are located between the two guide portions 39, and one signal terminal holding portion 31 is located between the two power terminal holding portions 34. The guide portions 39 are the portions that first come into contact with the mating connector 90 when the floating connector 10 and the mating connector 90, which are located apart from each other, approach each other along the mating direction. By providing the guide portions 39, any misalignment between the movable housing 30 of the floating connector 10 and the mating connector 90 in the X and Y directions is corrected before the terminals come into contact with each other.

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 of a conductive material such as metal. The flat plate extends generally in the Z direction so as to be long in the Z direction while bending in the YZ plane. The cross section of the flat plate is, for example, rectangular. The short dimension of the rectangular cross section is the plate thickness direction, and the long dimension is the plate width direction. Each of the signal terminals 40 and the power terminals 60 is arranged with the plate width direction of the flat plate aligned along the X direction. The thickness of the flat plate in the Y direction at the portion where the flat plate extends parallel to the Z direction is the plate thickness.

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 separated 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 is elastically deformed while the second end 48 can follow the movable housing 30.

The first end 42 has a board connection portion 43 connected to the board B1 and a first held portion 44 held by the fixed housing 20. The board connection portion 43 is exposed below the fixed housing 20. The board connection portion 43 is formed in a shape that extends along the main surface of the board B1 and is formed so as to be surface mountable on the board B1. The board connection portion 43 may be formed in a pin shape that can be connected to the board B1 via a through hole. The first held portion 44 is press-fitted and held in the first 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 board width direction (X direction). One of the two press-fit protrusions 45 is provided in a portion that fits into the first hole portion 23H1, and the other is provided in a portion that fits into the second hole portion 23H2.

Three orthogonal bent portions 46 are provided on the first end portion 42. The three orthogonal bent portions 46 are provided at positions spaced apart from each other along the longitudinal direction of the signal terminal 40. The three orthogonal bent portions 46 are provided so that the main surfaces of the flat plate that are the inner periphery of the bend are in reverse order. The first orthogonal bent portion 46 located at the bottom of the three orthogonal bent portions 46 and the third orthogonal bent portion 46 located at the innermost side along the Y direction are bent so that the main surface facing outward along the Y direction of the flat plate is the inner periphery side. The second orthogonal bent portion 46 in the middle is bent so that the main surface facing inward along the Y direction of the flat plate is the inner periphery side. The first orthogonal bent portion 46 connected to the board connection portion 43 is bent at an angle slightly smaller than 90 degrees, but a bent portion of about 90 degrees plus or minus 10 degrees can also be considered as an orthogonal bent portion 46. The second orthogonal bent portion 46 and the third orthogonal bent portion 46 are bent at approximately 90 degrees.

Here, the second end 48 is held by the movable housing 30 with a holding force weaker than that at the first end 42. Here, the first end 42 is provided with a press-fit protrusion 45 that is press-fitted into the fixed housing 20. The second end 48 does not have a press-fit protrusion 45 that protrudes in the plate width direction and is press-fitted into the movable housing 30, unlike the press-fit protrusion 45 at the first end 42. As a result, the second end 48 is held by the movable housing 30 with a holding force weaker than that at the first end 42.

The holding force of the first end 42 in the fixed housing 20 and the holding force of the second end 48 in the movable housing 30 are, for example, holding forces along the mating direction. For example, the first end 42 is held more difficult to move along the mating direction than the second end 48. For example, the first end 42 may be held on the fixed housing 20 so as not to move along the mating direction even by a force generated when the movable housing 30 moves. In contrast, the second end 48 may be held on the movable housing 30 so as to be movable along the mating direction by a force generated when the movable housing 30 moves.

The second end 48 has a terminal portion 49 that connects with the terminal of the mating connector 90, and a second held portion 51 that is held by the movable housing 30. The terminal portion 49 has a leaf spring-shaped portion 50 that is bent in the plate thickness direction. The main portion of the second held portion 51 is lower than the leaf spring-shaped portion 50, and here includes the portion that is inserted into the second holding hole 33H.

From one end of the signal terminal 40 to the other end, the board connection portion 43, the first held portion 44, the connecting portion 54, the second held portion 51, and the terminal portion 49 are connected in this order. When assembling the floating connector 10, the signal terminal 40 is passed through the first holding hole 23H and the second holding hole 33H in that order, starting from the terminal portion 49 side. Because the terminal portion 49 is provided with the leaf spring-shaped portion 50, the dimension of the terminal portion 49 in the Y direction is greater than the plate thickness. To allow the terminal portion 49 to pass through, the dimension of each holding hole 23H, 33H in the Y direction is greater than the plate thickness.

In the second retaining hole 33H, the inner surfaces facing in the opposite directions along the plate thickness direction (here, the Y direction) of the signal terminal 40 are the first inner surface 33A and the second inner surface 33B. Here, the surface connected to the bottom surface of the retaining groove 32G is the first inner surface 33A. The distance between the first inner surface 33A and the second inner surface 33B is larger than the plate thickness of the signal terminal 40. The distance between the first inner surface 33A and the second inner surface 33B is larger than the dimension of the leaf spring-shaped portion 50 along the Y direction. This prevents the terminal portion 49 having the leaf spring-shaped portion 50 from contacting both the first inner surface 33A and the second inner surface 33B when passing through the second retaining hole 33H. The second retained portion 51 contacts both the first inner surface 33A and the second inner surface 33B while bending in the plate thickness direction. Therefore, here, the dimension of the second retained portion 51 along the Y direction is larger than the dimension of the leaf spring-shaped portion 50 along the Y direction. The second held portion 51, for example, is in slidable contact with both the first inner surface 33A and the second inner surface 33B.

The second retained portion 51 has two bent portions 52. The two bent portions 52 are bent so that the main surfaces facing in opposite directions are on the inner periphery side. The second retained portion 51 has two bent portions 52, so that the second retained portion 51 can contact both the first inner surface 33A and the second inner surface 33B facing in opposite directions of the second retaining hole 33H, which is larger than the plate thickness. The upper part of the second retained portion 51 above the two bent portions 52 extends upward while contacting the first inner surface 33A or the bottom surface of the retaining groove 32G connected thereto. The part of the second end 48 that extends from the second retained portion 51 to the spring-shaped portion 50 extends straight upward from the upper end of the second retained portion 51 along the retaining groove 32G. Both sides of the part in the X direction are separated from the adjacent signal terminal 40 by both side surfaces of the retaining groove 32G. The second held portion 51 extends downward below the lower bent portion 52 while contacting the second inner surface 33B.

Here, since the first inner surface 33A and the bottom surface of the retaining groove 32G are continuous, the bottom surface of the retaining groove 32G can also be considered as an extension of the first inner surface 33A. Therefore, the second retained portion 51 is considered to be in contact with the first inner surface 33A when it is in contact with the first inner surface 33A inside the second retaining hole 33H, as well as when it is in contact with the bottom surface of the retaining groove 32G outside the second retaining hole 33H. In addition, both of the two bent portions 52 of the second retained portion 51 may be inside the second retaining hole 33H. Both of the two bent portions 52 of the second retained portion 51 may be outside above the second retaining hole 33H. Of the two bent portions 52 of the second retained portion 51, the lower bent portion 52 may be inside the second retaining hole 33H, and the upper bent portion 52 may be outside above the second retaining hole 33H. The two bent portions 52 and the portion extending diagonally between the two bent portions 52 in the Z direction can also be considered as an offset portion that offsets the position along the Y direction of the signal terminal 40, which extends straight in the Z direction.

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 along the longitudinal direction of the connecting portion 54.

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.

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 along the Y direction of the signal terminal 40 that extends straight in the Z direction. Of the two offset portions 55A and 55B, the one located on the first end 42 side is the first offset portion 55A, and the one located on the second end 48 side is the second offset portion 55B. The position where the connecting portion 54 extends 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. Along the Y direction, the offset amount of the first offset portion 55A and the offset amount of the second offset portion 55B are the same. In addition, the first offset portion 55A and the second offset portion 55B are provided so as to have slopes of the same angle.

The first offset portion 55A is provided in the same orientation as the offset portion of the second held portion 51. Along the Y direction, 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. Here, the slope of the first offset portion 55A is provided to be steeper than the slope of the offset portion of the second held portion 51. The offset portions of the first offset portion 55A and the second held portion may be provided to have slopes of similar angles.

The fixed housing 20 and the movable housing 30 each have a retaining hole 23H, 33H through which the signal terminal 40 passes. The second retaining hole 33H of the movable housing 30 is located on an extension line of the first hole 23H1 of the fixed housing 20. The first hole 23H1 of the fixed housing 20 and the second retaining hole 33H of the movable housing 30 have the same shape and size in the XY plane except for the guide surface. The first hole 23H1 and the second retaining hole 33H are located at the same position on the XY plane and overlap when viewed from the fitting direction. For example, the size of the first hole 23H1 and the second retaining hole 33H in the X direction is approximately the same as the plate width in the part of the flat plate without the press-fit protrusion 45 (for example, the same or slightly smaller). The size of the first hole 23H1 and the second retaining hole 33H in the Y direction is the same as the offset amount in the Y direction of the second retained part 51 and the elastic part 55.

The connecting portion 54 is covered by the first cover portion 26 of the fixed housing 20 from one side along a first direction (here, the Y direction) intersecting the mating direction, and is covered by the second cover portion 36 of the movable housing 30 from the other side. The first cover portion 26 or the second cover portion 36 has a slope portion that is inclined with respect to the mating direction (here, the Z direction). The first cover portion 26 is provided with a first slope portion 27 as a slope portion. The second cover portion 36 is provided with a second slope portion 37 as a slope portion. As shown in FIG. 6, the first slope portion 27 and the second slope portion 37 do not have an uneven shape, and the first slope portion 27 and the second slope portion 37 may be smooth surfaces.

The distance between the first slope portion 27 and the second slope portion 37 along the first direction gradually increases from the second end portion 48 toward the first end portion 42. The lower end of the second slope portion 37 is located higher than the lower end of the first slope portion 27. The second slope portion 37 is a steeper slope with a larger angle of inclination in the Z direction than the first slope portion 27. The second cover portion 36 has a vertical surface portion 38 that continues below the second slope portion 37. The lower end of the vertical surface portion 38 extends downward beyond the lower end of the first slope portion 27. The lower end of the vertical surface portion 38 is located between a pair of holding bodies 23 of the fixed housing 20.

The power terminal 60 has a conductor cross-sectional area larger than that of the signal terminal 40. The power terminal 60 is held in a press-fit state in the movable housing 30. Here, 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 has a first end 62 held in the fixed housing 20, a second end 64 held in the movable housing 30, and a connecting portion 66 connecting the first end 62 and the second end 64.

The first end 62 of the power terminal 60 is longer in the Y direction than the first end 42 of the signal terminal 40. The first end 62 of the power terminal 60 also has three orthogonal bends, and the portion between the first and third orthogonal bends fits into the recess 25A of the holding body 25. For example, the first end 62 is pressed into and held in the power terminal holding portion 24 of the fixed housing 20.

The second end 64 of the power terminal 60 has a larger dimension in the plate thickness direction than the first end 62. 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. For example, the second end 64 is press-fitted and held in the power terminal holding portion 34 of the movable housing 30. The second end 64 extends straight in the Z direction. A spring-shaped portion 98 is provided on the mating power terminal 97, and no spring-shaped portion is provided on the power terminal 60. However, the power terminal 60 may be provided with a spring-shaped portion.

The connecting portion 66 of the power terminal 60 is also provided with an elastic portion 67. The elastic portion 67 extends in a trapezoidal wave shape along the fitting direction, similar to the elastic portion 55. Furthermore, in the middle portion along the extension direction of the power terminal 60, a slit 68 is formed in the middle portion in the plate width direction of the flat plate, extending along the extension direction. As a result, in the middle portion along the extension direction of the power terminal 60, the flat plate is divided in the plate width direction. Here, two parallel slits 68 are provided in one flat plate, and one flat plate is divided into three. One slit may be provided in one flat plate, and one flat plate may be divided into two. Three or more parallel slits 68 may be provided in one flat plate, and one flat plate may be divided into four or more. The slit 68 is formed over the entire connecting portion 66 along the extension direction. The slit 68 also reaches a part of the first end 62 and a part of the second end 64.

The movable housing 30 surrounds each of the power terminals 60 individually below the power terminal holding portion 34. As shown in FIG. 5, the holding holes 35H of the power terminal holding portion 34 widen and extend to the lower end of the movable housing 30. The movable housing 30 has a peripheral wall portion 35A that surrounds the connecting portion 66 of each power terminal 60 on all four sides while leaving a gap between the connecting portion 66 and the connecting portion 66. The movable housing 30 surrounds the multiple power terminals 60 collectively above the power terminal holding portion 34. The movable housing 30 has a peripheral wall portion 35B that extends upward from the outer edge of the upper portion of the power terminal holding portion 34.

Figure 9 is an enlarged side view of region IX in Figure 7. Figure 9 is an enlarged view of one orthogonal bend 46.

9, the signal terminal 40 has a first extension 56 that extends linearly and a second extension 57 that extends linearly in a direction intersecting the first extension 56. The first extension 56 and the second extension 57 are connected to each other via a plurality of bent portions that bend in the same direction. The plurality of bent portions are connected to each other via a linear extension. For example, in the orthogonal bend 46, a third extension 58 is provided that is interposed between the first extension 56 and the second extension 57 and extends linearly in a direction intersecting each of the first extension 56 and the second extension 57. One bent portion C1 is interposed between the first extension 56 and the third extension 58. One bent portion C2 is interposed between the second extension 57 and the third extension 58. The bent portion C1 and the bent portion C2 are connected to each other by the flat third extension 58. Here, two bends C1 and C2 are provided between the first extension 56 and the second extension 57, but three or more bends may be provided.

9, the curved extension portion 59 shown by a virtual line is a virtual extension portion in which the first extension portion 56 and the second extension portion 57 are connected with a constant bend R in place of the third extension portion 58. The curved extension portion 59 is a circular arc, and the first extension portion 56 and the second extension portion 57 are tangents to the circular arc. Here, the outer surface of the signal terminal 40 from the first extension portion 56 to the second extension portion 57 on the outer periphery side of the two bend portions C1 and C2 is a C-chamfered surface. In contrast, the surface of the signal terminal 40 from the first extension portion 56 to the second extension portion 57 on the outer periphery side of the virtual curved extension portion 59 is an R-chamfered surface. As shown in FIG. 9, the outer surface of the third extension portion 58 is located on the inner periphery side of the outer surface of the curved extension portion 59. In this way, the first extension portion 56 and the second extension portion 57 are connected via one or more straight extension portions, and the one or more straight extension portions are preferably provided so that the outer peripheral surface of the one or more straight extension portions is located more inward than the outer peripheral surface of the imaginary curved extension portion 59.

9, the line segments L1, L2, and L3 shown by virtual lines are virtual lines along the extension directions of the extension portions 56, 57, and 58, respectively. Angle A1 is the bending angle of the second extension portion 57 relative to the first extension portion 56. Here, the bending angle of the second extension portion 57 relative to the first extension portion 56 is the bending angle until the first extension portion 56 extends in the extension direction of the second extension portion 57 when the first extension portion 56 is assumed to extend in a straight line. The same applies to the following bending angles. Angle A2 is the bending angle of the third extension portion 58 relative to the first extension portion 56, and angle A3 is the bending angle of the third extension portion 58 relative to the second extension portion 57. Angles A2 and A3 are smaller than angle A1. In the example shown in FIG. 9, angle A1 is an angle that intersects at right angles. Angle A1 may be an angle other than perpendicular. Angle A2 and angle A3 may be the same angle as each other or may be different. It is preferable that the difference between angles A2 and A3 is as small as possible. When angle A1 is a perpendicular angle, angles A2 and A3 may be, for example, in the range of 45 degrees plus or minus 5 degrees.

The signal terminal 40 has a plurality of bent portions, including the bent portion 52 of the second held portion 51. The angles of these bent portions are preferably smaller than 45 degrees plus or minus 5 degrees, such as angles A2 and A3. Here, the angles of the bent portions at the offset portions 55A and 55B of the elastic portion 55, the bent portion 52 of the second held portion 51, and the bent portion at the spring-shaped portion 50 are smaller than 45 degrees plus or minus 5 degrees, such as angles A2 and A3. For example, when it is desired to bend the signal terminal 40 by more than 50 degrees, it is preferable to interpose a short linear extension portion such as the third extension portion 58 so that the bent angle of each bent portion 52 is smaller than 45 degrees plus or minus 5 degrees.

<Regarding the Mating Connector 90>
The mating connector 90 has a mating housing 91, a plurality of mating signal terminals 95, and a plurality of mating power terminals 97. The mating housing 91 holds the plurality of mating terminals 95, 97 in the same arrangement as the plurality of terminals 40, 60. The mating housing 91 has a signal terminal holding portion 92 that holds the mating signal terminal 95, a power terminal holding portion 93 that holds the mating power terminal 97, and a guide receiving portion 94 that contacts the guide portion 39. The mating signal terminal 95 has a spring-shaped portion 96. The mating power terminal 97 has a spring-shaped portion 98 and is formed in a cylindrical shape into which the second end 64 of the power terminal 60 is inserted. The signal terminal holding portion 31 of the movable housing 30 is fitted into the signal terminal holding portion 92 of the mating connector 90, and the power terminal holding portion 34 of the movable housing 30 is fitted into the power terminal holding portion 93 of the mating connector 90. Before these are fitted, the guide portion 39 is brought into contact with the guide receiving portion 94, thereby correcting misalignment in the X direction and Y direction.

<Mating of the floating connector 10 with the mating connector 90>
When connecting the floating connector 10 and the mating connector 90, an operator moves the floating connector 10 and the mating connector 90 relative to each other in the fitting direction. Here, the boards B1 and B2 are moved relative to each other in the fitting direction.

When the floating connector 10 and the mating connector 90 approach each other, the guide portion 39 comes into contact with the guide receiving portion 94 of the mating connector 90 and is guided. At this time, if there is a misalignment between the floating connector 10 and the mating connector 90 along the X and Y directions, the movable housing 30 moves in the direction in which the misalignment occurs. When the movable housing 30 moves, the second end 48 of the signal terminal 40 and the second end 64 of the power terminal 60 receive a force from the movable housing 30 at the contact surface with the movable housing 30. For example, when the movable housing 30 moves leftward from the state shown in FIG. 4, the left signal terminal 40 receives a leftward force from the first inner surface 33A and the bottom surface of the holding groove 32G. The right signal terminal 40 receives a leftward force from the second inner surface 33B. As a result, the elastic portion 55 of the signal terminal 40 and the elastic portion 67 of the power terminal 60 elastically deform, and the second end 48 of the signal terminal 40 and the second end 64 of the power terminal 60 follow the movable housing 30. As a result, the misalignment between the floating connector 10 and the mating connector 90 in the X and Y directions is corrected.

Now, let us consider the case where the signal terminal 40 is subjected to a force from the movable housing 30 and elastically deforms when the movable housing 30 moves.

Consider a hypothetical case in which the first end 42 and the second end 48 are held by the same holding force by providing a press-in protrusion on each of the first end 42 and the second end 48. In this case, when the movable housing 30 moves relative to the fixed housing 20, the part of the first end 42 where the press-in protrusion is provided is held at a predetermined position on the fixed housing 20, and the part of the second end 48 where the press-in protrusion is provided is held at a predetermined position on the movable housing 30. Therefore, a relatively large tensile stress along the terminal extension direction is generated in the part between the press-in protrusion of the first end 42 and the press-in protrusion of the second end 48. In particular, since the second end 48 is the moving side, a relatively large tensile stress along the terminal extension direction is generated near the press-in protrusion of the second end 48.

In contrast, here, the holding force of the second end 48 in the movable housing 30 is smaller than the holding force of the first end 42 in the fixed housing 20. Therefore, compared to a hypothetical case in which a press-fit protrusion is provided on each of the first end 42 and the second end 48, the tensile stress along the terminal extension direction is smaller on the second end 48 side than the press-fit protrusion 45 of the first end 42.

When the second end 48 is movable in the fitting direction relative to the second retaining hole 33H, the second end 48 can move in the fitting direction relative to the second retaining hole 33H on the second end 48 side of the press-fit protrusion 45 of the first end 42, thereby releasing the tensile stress along the terminal extension direction.

With the second end 48 of the signal terminal 40 and the second end 64 of the power terminal 60 following the movable housing 30, the signal terminal holders 31 and 92 fit together, and the power terminal holders 34 and 93 fit together. This electrically connects the signal terminals 40 and 95, and electrically connects the power terminals 60 and 97.

The spring-shaped portion 96 of the mating signal terminal 95 contacts between the spring-shaped portion 50 and the second held portion 51 of the signal terminal 40. The length between the 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 96 of the mating signal terminal 95. If the positions of the boards B1 and B2 are misaligned in the Z direction, the position at which the spring-shaped portion 96 of the mating signal terminal 95 contacts the signal terminal 40 along the Z direction changes. In addition, the terminal portion of the power terminal 60 extends in a straight line. The insertion amount of the terminal portion of the power terminal 60 into the cylindrical portion of the mating power terminal 97 can be changed. 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 97 changes. As a result, the positional deviation in the Z direction is also absorbed.

Figure 10 is an explanatory diagram showing the state in which the movable housing 30 has moved. In Figure 10, the movable housing 30 has moved to the left along the Y direction. In Figure 10, the amount of movement of the movable housing 30 in the Y direction is almost at its maximum.

As shown in FIG. 10, when the first cover part 26 and the second cover part 36 approach each other in the Y direction and the amount of movement of the movable housing 30 relative to the fixed housing 20 is maximized, the connecting part 54 is separated from the first cover part 26 or the second cover part 36 in the Y direction at any position along the mating direction. In the example shown in FIG. 10, the connecting part 54 is separated from the first cover part 26 and the second cover part 36 in the Y direction at any position along the mating direction.

In this embodiment, the signal terminal 40, the first cover part 26, and the second cover part 36 are provided in a symmetrical shape, with one pair on each side. In this embodiment, when one pair of the two pairs of the first cover part 26 and the second cover part 36 on the left and right approaches each other along the Y direction, the first cover part 26 and the second cover part 36 of the other pair moves away from each other along the Y direction. In the example shown in FIG. 10, the first cover part 26 and the second cover part 36 of the left pair move toward each other along the Y direction while the amount of movement of the movable housing 30 relative to the fixed housing 20 is maximized. At this time, the connecting parts 54, 66 of the left signal terminal 40 are separated from the first cover part 26 or the second cover part 36 along the Y direction at any position along the mating direction.

Note that Figure 4 shows the state in which the movable housing 30 is in the initial position (nominal state with no positional deviation). As shown in Figure 4, when the movable housing 30 is in the initial position, the connecting portion 54 of the signal terminal 40 is separated from the first cover portion 26 and the second cover portion 36 along the Y direction at any position along the mating direction. Therefore, in a state in which the first cover portion 26 and the second cover portion 36 are further away from each other in the Y direction than in this state (the state on the right side of Figure 10), the connecting portion 54 of the signal terminal 40 is naturally separated from the first cover portion 26 and the second cover portion 36 along the Y direction at any position along the mating direction.

<Effects, etc.>
According to the floating connector 10 configured as above, the second end 48 of the signal terminal 40 is held by the movable housing 30 with a holding force weaker than that at the first end 42. Here, if the second end 48 is held by the movable housing 30 with a holding force equal to or greater than that at the first end 42, a large stress may be applied to the elastically deformed portion of the coupling portion 54 when the movable housing 30 moves. In this case, it is necessary to take measures such as lengthening the length of the coupling portion 54 in order to disperse the stress. In the present disclosure, since the second end 48 is held by the movable housing 30 with a holding force weaker than that at the first end 42, it is possible to suppress the application of a large stress to the elastically deformed portion of the coupling portion 54 when the second end 48 moves following the movable housing 30. This makes it possible to suppress the length of the coupling portion 54 from being increased, thereby suppressing adverse effects on communication performance. As a result, good communication performance can be obtained in the floating connector 10.

The second end 48 of the signal terminal 40 is held in the second retaining hole 33H so that it can move along the longitudinal direction of the signal terminal 40. As a result, since the second end 48 is movable relative to the second retaining hole 33H, when stress is applied to the signal terminal 40, stress is less likely to concentrate on a specific portion of the second end 48. This further reduces the need to increase the length of the signal terminal 40 to distribute stress.

The second end 48 is in contact with both the first inner surface 33A and the second inner surface 33B while bending inside the second retaining hole 33H. This makes it easier for the second end 48 to follow the movable housing 30 regardless of whether the movable housing 30 moves to one side or the other side along the plate thickness direction of the signal terminal 40.

The second retaining hole 33H of the movable housing 30 is located on an extension line of the first hole 23H1 of the fixed housing 20. This makes it easier to pass the signal terminal 40 through the first retaining hole 23H of the fixed housing 20 and the second retaining hole 33H of the movable housing 30 when assembling the floating connector 10. In addition, the width dimension (dimension in the Y direction) of the floating connector 10 can be made smaller than when the retaining holes 23H and 33H are separated in the Y direction.

The first end 42 of the signal terminal 40 is provided with a press-fit protrusion 45 that is press-fitted into the fixed housing 20, while the second end 48 is not provided with a press-fit protrusion 45 that is press-fitted into the movable housing 30. This allows configurations with different holding forces to be provided with a simple structure.

One of the factors that may cause deterioration in communication performance is attenuation due to reflection at the bent portion 52. In the present disclosure, the first extension portion 56 and the second extension portion 57 are connected via multiple bent portions 52 that bend in the same direction, so that the bending angle of each of the multiple bent portions 52 is gentle. This makes it easier for reflected waves at the bent portions 52 to travel in the propagation direction. This makes it less likely that attenuation due to reflection at the bent portions 52 will occur, and deterioration in communication performance can be suppressed.

In addition, since the elastic portion 55 is provided at the connecting portion 54 of the signal terminal 40, the elastic portion 55 is easily elastically deformed when the second end 48 follows the movable housing 30. In addition, since the elastic portion 55 extends in a trapezoidal wave shape from the first end 42 to the second end 48, the width dimension (dimension along the Y direction) of the floating connector 10 can be made smaller than when the elastic portion 55 is formed in a multi-step staircase shape or a U-shape that reciprocates along the mating direction.

In addition, the power terminal 60, which has a conductor cross-sectional area larger than that of the signal terminal 40, is press-fitted into the movable housing 30. This allows the movable housing 30 to be firmly supported via the power terminal 60.

[Additional Notes]
A floating connector according to a modified example and a connector device including the same will be described. Fig. 11 is an exploded perspective view showing a connector device 200 according to a modified example. Fig. 12 is an exploded front view showing a connector device 200 according to a modified example. Fig. 13 is a cross-sectional view taken along line XI-XI in Fig. 12. Fig. 14 is a cross-sectional view taken along line XII-XII in Fig. 12. Fig. 15 is a perspective view showing a signal terminal 140. Fig. 16 is a perspective view showing a power terminal 160. In the following description, components similar to those described thus far are designated by the same reference numerals and description thereof will be omitted.

In the floating connector 110 according to this modified example, the connecting portion 154 of the signal terminal 140 extends linearly from the first end 42 toward the second end 48. This makes it easier to shorten the length of the signal terminal 140. Furthermore, the first slope portion 127 of the fixed housing 120 and the second slope portion 137 of the movable housing 130 are parallel to each other. This allows the first slope portion 127 and the second slope portion 137 to cover the connecting portion 154 at a position closer to the connecting portion 154.

In addition, in the floating connector 110, the first end 62 and the second end 64 of the power terminal 160 are spaced apart in the Y direction, not in the Z direction. The elastic portion 167 of the power terminal 160 is formed in a U shape.

So far, it has been described that the holding force of the second end 48 of the movable housing 30 is weaker than the holding force of the first end 42 of the fixed housing 20, but this is not a required configuration. The holding force of the second end 48, 64 of the movable housing 30 may be the same as or stronger than the holding force of the first end 42, 62 of the fixed housing 20. The press-fit protrusion 45 may be provided on both the first end 42, 62 and the second end 48, 64.

So far, it has been described that the fixed housing 20 has the first cover portion 26, the movable housing 30 has the second cover portion 36, and the first cover portion 26 or the second cover portion 36 has a sloped portion, but this is not a required configuration. For example, either one or both of the first cover portion 26 and the second cover portion 36 may not be provided. Also, when both the first cover portion 26 and the second cover portion 36 are provided, neither the first cover portion 26 nor the second cover portion 36 may have a sloped portion.

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