Description

Shielding member pair

[0001] The present disclosure relates to a shield member pair.

[0002] Patent Document 1 discloses a shielding member.

[0003] Japanese Patent Application Laid-Open No. 2021-096933

[0004] An object of the present disclosure is to provide a pair of shielding members with high shielding performance.

[0005] The pair of shielding members according to the first aspect is a pair of shielding members for shielding an object to be shielded, the pair of shielding members comprising a first shielding member attached to a first attachment object and a second shielding member attached to a second attachment object, the first shielding member and the second shielding member facing each other in the vertical direction, the first shielding member having a first shielding portion that shields the object to be shielded from a direction perpendicular to the vertical direction, the second shielding member having a second shielding portion that shields the object to be shielded from a direction perpendicular to the vertical direction, and the pair of shielding members comprising a covering portion that blocks a gap between the first shielding portion and the second shielding portion from a direction perpendicular to the vertical direction.

[0006] In this aspect, the shield member pair includes a first shield member attached to a first attachment object and a second shield member attached to a second attachment object. The first shield member and the second shield member face each other in the vertical direction. The first shield member has a first shield portion that shields the object to be shielded from a direction perpendicular to the vertical direction, and the second shield member has a second shield portion that shields the object to be shielded from a direction perpendicular to the vertical direction. Therefore, the first shield portion and the second shield portion can shield the object to be shielded from a direction perpendicular to the vertical direction.

[0007] However, a gap may occur between the first shielding portion and the second shielding portion in the vertical direction. This gap reduces shielding performance. Therefore, in this embodiment, the pair of shielding members includes a cover portion that closes the gap between the first shielding portion and the second shielding portion in a direction perpendicular to the vertical direction. This prevents a reduction in shielding performance and realizes a pair of shielding members with high shielding performance.

[0008] The "vertical direction" refers to a direction relative to the shield member. Therefore, it does not limit the orientation of the shield member during use. For example, the downward direction of the shield member may or may not face the direction of gravity. Furthermore, in the embodiment described below, the vertical direction is a direction perpendicular to the surface of the first substrate, which serves as the first attachment object. However, the vertical direction in this aspect may be, for example, a direction parallel to the surface of the first substrate. Furthermore, in the embodiment described below, the first shield member and the second shield member are configured to contact each other. However, this aspect is not limited to this. Furthermore, in the embodiment described below, the first shield member and the second shield member are electrically connected to each other. However, this aspect is not limited to this. For example, the first shield member and the second shield member may contact each other but not be electrically connected. Furthermore, in the embodiment described below, the first shield member and the second shield member contact each other in a contact region extending in the longitudinal direction. However, this aspect is not limited to this. For example, the first shielding member may have a plurality of convex contact portions arranged in the longitudinal direction of the first shielding member, and the plurality of convex contact portions may contact the second shielding member. In the embodiment described below, the first shielding member is electrically connected to the first attachment object, but this aspect is not limited to this. The same applies to the second shielding member.

[0009] The pair of shielding members according to the second aspect is the same as that of the first aspect, in which the first shielding member has a first contact portion, the second shielding member has a second contact portion, the first contact portion and the second contact portion are in contact with each other, and at least one of the first contact portion and the second contact portion is a contact plane portion perpendicular to the vertical direction.

[0010] In this aspect, the first shielding member has a first contact portion, and the second shielding member has a second contact portion. The first contact portion and the second contact portion are in contact with each other, thereby electrically connecting the first shielding member and the second shielding member.

[0011] In this embodiment, at least one of the first contact portion and the second contact portion is a flat contact portion that is perpendicular to the vertical direction, so that the first shielding member and the second shielding member can be electrically connected even if they are misaligned in the direction perpendicular to the vertical direction.

[0012] A third aspect of the present invention provides a pair of shield members according to the second aspect, wherein the cover portion extends from the contact plane portion.

[0013] In this aspect, the cover portion extends from the flat contact portion, so that the cover portion can effectively cover the gap formed in the vicinity of the flat contact portion.

[0014] In the embodiment described below, the cover portion has a curved portion and a flat portion, but the cover portion of this embodiment is not limited to this.

[0015] The pair of shield members according to the fourth aspect is any one of the first to third aspects, in which the first shield member has a fixed portion fixed to the first attachment object and a movable portion that can be displaced in the vertical direction relative to the fixed portion, and the movable portion has a movable shield portion as the first shield portion.

[0016] In this aspect, the first shield member includes a fixed portion that is fixed to the first attachment object and a movable portion that is vertically displaceable relative to the fixed portion. The movable portion has a movable shield portion that serves as the first shield member. This allows for vertical positional misalignment between the first shield member and the second shield member to be accommodated.

[0017] In the embodiment described below, the movable part is displaceable relative to the fixed part in both the up-down direction and two directions perpendicular to the up-down direction, and is also displaceable so as to rotate slightly around an axis such as an axis in the up-down direction or an axis perpendicular to the up-down direction. However, this aspect is not limited to this. For example, the movable part of this aspect may be displaceable only in the up-down direction relative to the fixed part.

[0018] A fifth aspect of the shielding member pair is the fourth aspect, in which the first shielding member has an elastic support portion that supports the movable portion so that it can be displaced, the elastic support portion has a spring piece that connects the fixed portion and the movable portion, and the second shielding member has the covering portion.

[0019] In this aspect, the first shield member includes an elastic support portion that supports the movable portion so that the movable portion can be displaced. The elastic support portion has a spring piece that connects the fixed portion and the movable portion. Therefore, the movable portion can be elastically displaced.

[0020] However, if a cover portion is provided on the first shielding member, the structure of the first shielding member provided with the spring pieces becomes more complicated, which may make it impossible to realize a structure that ensures shielding performance. Therefore, in this aspect, the second shielding member includes a cover portion. That is, the cover portion is provided on the second shielding member. This prevents the structure of the first shielding member from becoming complicated.

[0021] A shielding member according to a sixth aspect is the shielding member of the fourth or fifth aspect, wherein the movable portion does not have a portion fixed to the object to be shielded.

[0022] In this aspect, the movable part does not have a portion that is fixed to the object to be shielded, which eliminates the need to provide the movable part with a structure for fixing it to the object to be shielded, thereby simplifying the structure of the first shield member.

[0023] In the embodiment described below, the movable part does not have a part that physically engages with the object to be shielded, but the movable part of this aspect is not limited to this. The movable part of this aspect may have a part that physically engages with the object to be shielded, as long as it does not have a part that is fixed to the object to be shielded. An example of a case in which the movable part has a part that physically engages with the object to be shielded is a case in which the movable part is in slidable contact with the object to be shielded.

[0024] A shielding member according to a seventh aspect is the shielding member of the fourth or fifth aspect, wherein the movable portion does not have a portion that physically engages with the object to be shielded.

[0025] In this embodiment, the movable part does not have a part that physically engages with the object to be shielded. Therefore, it is not necessary to provide the movable part with a structure for physically engaging with the object to be shielded. As a result, the structure of the shielding member can be simplified.

[0026] A shielding member according to an eighth aspect is any one of the first to fifth aspects, wherein the first shielding member does not have a portion that is fixed to the object to be shielded.

[0027] In this aspect, the first shielding member does not have a portion that is fixed to the object to be shielded. Therefore, it is not necessary to provide the first shielding member with a structure for fixing it to the object to be shielded. As a result, the structure of the first shielding member can be simplified.

[0028] Furthermore, if it becomes unnecessary to provide the shielding member with a structure for fixing it to the object to be shielded, it becomes easier to use one type of shielding member to accommodate multiple types of objects to be shielded. In other words, even if the size or shape of the object to be shielded changes, it becomes easy to shield it with a shielding member of the same structure.

[0029] The shielding member of the ninth aspect is the fourth or fifth aspect, wherein the movable part does not have a part that is fixed to the object to be shielded, and the fixed part has a part that is fixed to the object to be shielded.

[0030] In this aspect, the movable part does not have a portion that is fixed to the object to be shielded. Therefore, it is not necessary to provide the movable part with a structure for fixing it to the object to be shielded. Also, in this aspect, the fixed part has a portion that is fixed to the object to be shielded. Therefore, it is possible to handle the object to be shielded and the shielding member as a single unit.

[0032] Preferred embodiments of the present disclosure will be described below.

[0033] In addition, the +X direction of the arrow shown in each drawing may be described as one side in the width direction, the +Y direction of the arrow as one side in the front-rear direction, and the +Z direction of the arrow as the upper side in the up-down direction. However, this does not limit the position of the shield member etc. when in use.

[0034] 1 and 2 show a shield structure 100 according to an embodiment.

[0035] The shield structure 100 includes attachment objects 91 and 92 , electronic components 11 and 12 , and shields 21 and 22 .

[0036] In the shielding structure 100, electronic components 11 and 12, which are "shielded objects", are shielded by shields 21 and 22. The electronic components 11 and 12 and the shields 21 and 22 are attached to attachment objects 91 and 92, respectively.

[0037] The attachment objects 91, 92 include a first attachment object 91 and a second attachment object 92. The first attachment object 91 is a first substrate 91, and the second attachment object 92 is a second substrate 92. The first substrate 91 and the second substrate 92 are disposed opposite each other with their thickness directions facing the same direction (Z direction). Hereinafter, the first substrate 91 may be simply referred to as the substrate 91, and the second substrate 92 may be referred to as the mating substrate 92.

[0038] The electronic components 11, 12 are a connector pair 11, 12 consisting of a first connector 11 and a second connector 12. The first connector 11 is attached to a first attachment object 91, and the second connector 12 is attached to a second attachment object 92. When the first connector 11 and the second connector 12 are connected, the first board 91 and the second board 92 are electrically connected (see FIG. 2 ). Hereinafter, the first connector 11 may be simply referred to as the connector 11, and the second connector 12 may be referred to as the mating connector 12.

[0039] 1, the first connector 11 is a floating connector. The first connector 11 includes a first terminal portion 31 formed with at least one first terminal 31, and a first housing portion 32 that holds the first terminal portion 31. The first housing portion 32 includes a fixed housing 33 fixed to a first attachment object 91, and a movable housing 34 that is movable relative to the fixed housing 33. The movable housing 34 is movable in any of the X, Y, and Z directions, as well as directions oblique to these directions.

[0040] The first terminal 31 has a connection portion 31a that is connected to the first attachment object 91 by soldering, and a contact portion 31b that comes into contact with the second terminal 41 of the second connector 12. The first terminal 31 is held by both the fixed housing 33 and the movable housing 34. An elastically deformable portion is formed between the portion of the first terminal 31 that is held by the fixed housing 33 and the portion that is held by the movable housing 34. This allows the movable housing 34 to be displaced.

[0041] The second connector 12 is not a floating connector. The second connector 12 includes a second terminal portion 41 including at least one second terminal 41, and a second housing portion 42 that holds the second terminal portion 41. The second housing portion 42 includes a fixed housing 43 that is fixed to the second mounting object 92, and does not include a movable housing that is displaceable relative to the second mounting object 92. The second terminal 41 includes a connection portion 41a that is connected to the second mounting object 92 by soldering, and a contact portion 41b that comes into contact with the first terminal 31.

[0042] The first terminal portion 31 includes a plurality of first signal terminals 31A. The plurality of first signal terminals 31A are configured by arranging a large number of pairs of first signal terminals 31A in the X direction. The second terminal portion 41 includes a plurality of second signal terminals 41A. The plurality of second signal terminals 41A are configured by arranging a large number of pairs of second signal terminals 41A in the X direction. The contact portions 31b of the pair of first signal terminals 31A contact the contact portions 41b of the pair of second signal terminals 41A so as to sandwich them from the outside in the Y direction (see FIGS. 1 and 2 ).

[0043] The first terminal portion 31 includes a plurality of first power supply terminals 31B. The second terminal portion 41 includes a plurality of second power supply terminals 41B. The plurality of first power supply terminals 31B are arranged in an area on one side in the X direction and an area on the other side in the X direction with respect to the area where the plurality of first signal terminals 31A are arranged. The same applies to the plurality of second power supply terminals 41B.

[0044] The contact pressure generated by contact between the contact portion 31b of the first signal terminal 31A and the contact portion 41b of the second signal terminal 41A occurs in a plane (within the XY plane) perpendicular to the direction in which the first attachment object 91 and the second attachment object 92 face each other (Z direction).

[0045] The contact pressure generated by contact between the first power supply terminal 31B and the second power supply terminal 41B also occurs in a plane (XY plane) perpendicular to the direction in which the first attachment object 91 and the second attachment object 92 face each other (Z direction).

[0046] (Shields 21 and 22) The shields 21 and 22 are a pair of shield members 21 and 22 composed of a first shield member 21 and a second shield member 22.

[0047] (First shielding member 21) The first shielding member 21 is made by subjecting a single piece of conductive plate material to processes such as punching and bending, etc. Therefore, one part of the first shielding member 21 is connected to another part without any joint therebetween.

[0048] The first shield member 21 has a cylindrical shape (specifically, a rectangular cylindrical shape) and is substantially symmetrical in both the X direction and the Y direction.

[0049] 4, a joint 21h is formed at one side in the Y direction (+Y direction side) of the cylindrical first shielding member 21, where ends of the plates constituting the first shielding member 21 are joined together. The joint 21h is provided at the center of the first shielding member 21 in the X direction.

[0050] The first shielding member 21 has a fixed portion 50 fixed to a first substrate 91 as the "first mounting object", a movable portion 60 displaceable relative to the fixed portion 50, and an elastic support portion 70 that supports the movable portion 60 so that it can be displaced.

[0051] (Fixed Part 50 ) The fixed part 50 includes a fixed shield part 51 .

[0052] The fixed shield part 51 includes a pair of first wall parts 51a facing each other in the X direction and a pair of second wall parts 51b facing each other in the Y direction. The first wall parts 51a are wall parts extending in the Y direction and are flat plates with their thickness direction facing the X direction. The second wall parts 51b are wall parts extending in the X direction and are flat plates with their thickness direction facing the Y direction. As a result, the fixed shield part 51 is formed in a cylindrical shape (specifically, a rectangular cylindrical shape). The fixed shield part 51 is sometimes referred to as the cylindrical part 51. The first wall parts 51a and the second wall parts 51b are connected via a curved part extending in the vertical direction. As a result, the cylindrical part 51 is completely cylindrical.

[0053] The fixing portion 50 includes a plurality of connecting portions 52 a, 52 b, and 52 c. Each of the plurality of connecting portions 52 a, 52 b, and 52 c is joined by soldering to a pad (not shown) formed on the upper surface of the first substrate 91. This attaches the first shielding member 21 to the first substrate 91 and electrically connects the first shielding member 21 and the first substrate 91 together.

[0054] The plurality of connection portions 52 a, 52 b, 52 c include a plurality of first connection portions 52 a protruding from the first wall portion 51 a. Each of the first connection portions 52 a has a shape that protrudes downward from the lower edge of the first wall portion 51 a. A plurality (two) of the first connection portions 52 a are formed for each of the first wall portions 51 a.

[0055] The plurality of connection portions 52a, 52b, 52c include a plurality of second connection portions 52b protruding from the second wall portion 51b. The second connection portions 52b have a shape that protrudes downward from the lower edge of the second wall portion 51b. A plurality (eight) of the second connection portions 52b are formed for each second wall portion 51b.

[0056] The connecting portions 52a, 52b, and 52c include four third connecting portions 52c whose thickness directions are oriented in the up-down direction. The third connecting portions 52c are connected to the second wall portion 51b via curved portions.

[0057] The fixed part 50 has a plurality of notches 54. The notches 54 are formed in the second wall part 51b of the fixed shield part 51. Specifically, each of the pair of second wall parts 51b has two notches 54. The notches 54 are portions formed by cutting out a part near the lower edge of the fixed shield part 51. The positions of the notches 54 correspond to the positions where the first power supply terminal 31B of the first connector 11 is disposed. This ensures an appropriate distance between the fixed shield part 51 and the first power supply terminal 31B.

[0058] The fixing portion 50 has a carrier cutting portion 55. The carrier cutting portion refers to a portion that was connected to the carrier when the shielding member was manufactured by progressive processing and that is ultimately cut off. The carrier cutting portion 55 is formed on one of the pair of second wall portions 51b on the side opposite the second wall portion 51b on which the joint portion 21h is provided. Two carrier cutting portions 55 are formed with an interval in the X direction.

[0059] (Moving Part 60) The moving part 60 is cylindrical (specifically, rectangular cylindrical).

[0060] The movable portion 60 includes movable shield portions 61 and 62 .

[0061] The movable shield parts 61 and 62 include an inner cylindrical part 61 and an outer cylindrical part 62 arranged outside the inner cylindrical part 61 .

[0062] The inner cylindrical portion 61 includes a pair of first inner wall portions 61a facing each other in the X direction and a pair of second inner wall portions 61b facing each other in the Y direction. The first inner wall portions 61a are wall portions extending in the Y direction and are flat plates with their thickness directions facing the X direction. The second inner wall portions 61b are wall portions extending in the X direction and are flat plates with their thickness directions facing the Y direction. The first inner wall portions 61a and the second inner wall portions 61b are connected via a curved portion extending in the vertical direction. Therefore, the inner cylindrical portion 61 is completely cylindrical.

[0063] The outer cylindrical portion 62 includes a pair of first outer wall portions 62a facing each other in the X direction and a pair of second outer wall portions 62b facing each other in the Y direction. The first outer wall portions 62a are wall portions extending in the Y direction and are flat plate-shaped with their thickness direction facing the X direction. The second outer wall portions 62b are wall portions extending in the X direction and are flat plate-shaped with their thickness direction facing the Y direction. A gap is formed between the first outer wall portions 62a and the second outer wall portions 62b. Therefore, the outer cylindrical portion 62 is not completely cylindrical, but is approximately cylindrical.

[0064] In connection with the formation of the joint portion 21h on one side in the Y direction of the first shield member 21, the second outer wall portion 62b on one side in the Y direction is separated into two portions.

[0065] The outer cylindrical portion 62 is connected to the inner cylindrical portion 61 via a plurality of folded portions 63 a, 63 b. Specifically, the first outer wall portion 62 a is connected to the first inner wall portion 61 a via the first folded portion 63 a. The second outer wall portion 62 b is connected to the second inner wall portion 61 b ​​via a plurality of second folded portions 63 b.

[0066] The second outer wall portion 62b is disposed outside the elastic support portion 70. As a result, the second outer wall portion 62b closes the gap formed around the elastic support portion 70. The second outer wall portion 62b may be referred to as a closing wall portion 62b.

[0067] To put it another way, a gap is formed in the vertical direction between the cylindrical portion 51 of the fixed portion 50 and the inner cylindrical portion 61 of the movable portion 60. The first outer wall portion 62a and the second outer wall portion 62b that constitute the outer cylindrical portion 62 function to close this gap. Since the elastic support portion 70 is disposed in the gap between the cylindrical portion 51 and the inner cylindrical portion 61, the above-mentioned gap formed around the elastic support portion 70 can be said to be part of the gap between the cylindrical portion 51 and the inner cylindrical portion 61.

[0068] (Opposite Plate Portions 64b) The movable portion 60 has a plurality of (four) opposed plate portions 64b.

[0069] The plurality of opposing plate portions 64b include a plurality (two) of opposing plate portions 64b on the +Y direction side and a plurality (two) of opposing plate portions 64b on the −Y direction side. Hereinafter, when no particular distinction is made, they will simply be referred to as opposing plate portions 64b.

[0070] The opposing plate portion 64b is a flat plate with its thickness oriented in the up-down direction. The opposing plate portion 64b is a substantially rectangular shape with its longitudinal direction in the X direction and its transverse direction in the Y direction. The opposing plate portion 64b is connected to the inner cylindrical portion 61 via a curved portion 65b bent at approximately 90 degrees. Specifically, the opposing plate portion 64b is provided so as to extend from the second inner wall portion 61b of the inner cylindrical portion 61. The opposing plate portion 64b is located outside (outside in the Y direction) the inner cylindrical portion 61.

[0071] The opposing plate portion 64b comes into contact with the second shield member 22, which is the "contact object." In other words, the opposing plate portion 64b functions as a contact portion 64b that comes into contact with the second shield member 22, which is the "contact object." This electrically connects the first shield member 21 and the second shield member 22.

[0072] The upper surface of the opposing plate portion 64b contacts the second shield member 22. The upper surface of the opposing plate portion 64b is flat. The opposing plate portion 64b may be referred to as a flat contact portion 64b.

[0073] The contact portion 64b comes into contact with the second shielding member 22 so as to receive a downward force from the second shielding member 22. Therefore, the movable portion 60 is easily displaced downward by the force from the second shielding member 22. Because the movable portion 60 is displaced elastically, the contact pressure is ensured by the elastic restoring force.

[0074] A second folded portion 63b is provided between two opposing plate portions 64b adjacent to each other in the X direction. In addition, a second folded portion 63b is provided on each of the +X direction and −X direction sides of the multiple opposing plate portions 64b aligned in the X direction.

[0075] (Covering portions 87 a, 87 b) The fixed portion 80 includes a plurality of covering portions 87 a, 87 b. The covering portions 87 a, 87 b function to close gaps in the vertical direction that may occur between the movable shield portions 61, 62 of the first shield member 21 and the fixed shield portion 81 of the second shield member 22.

[0076] The plurality of cover portions 87a, 87b are composed of a plurality of first cover portions 87a and a plurality of second cover portions 87b. Hereinafter, when no particular distinction is made, they will simply be referred to as cover portions 87a, 87b.

[0077] The cover portions 87 a, 87 b extend from the opposing plate portions 84 a, 84 b. Specifically, the cover portions 87 a, 87 b are each composed of a curved portion 87 a1, 87 b1 formed on the outer side (outer side in the X direction and outer side in the Y direction) of the opposing plate portions 84 a, 84 b, and a flat portion 87 a2, 87 b2 whose thickness direction is oriented perpendicular to the up-down direction.

[0078] The first covering portion 87a extends from the first opposing portion 84a. The first covering portion 87a is disposed on the outer side in the X direction of a gap that may occur between the movable shield parts 61, 62 and the fixed shield part 81. The width dimension (Y dimension) of the first covering portion 87a is the same as the width dimension of the first opposing portion 84a.

[0079] The second cover portion 87b extends from the second opposing portion 84b. The first cover portion 87a is disposed on the outer side in the Y direction of a gap that may occur between the movable shield parts 61, 62 and the fixed shield part 81. The width dimension (X dimension) of the second cover portion 87b is the same as the width dimension of the second opposing portion 84b.

[0080] The multiple cover portions 87a, 87b are formed in positions that do not prevent the fixed portion 80 of the second shielding member 22 from shifting in position relative to the movable portion 60 of the first shielding member 21 in a plane direction perpendicular to the vertical direction (XY plane direction).

[0081] (Elastic support portion 70) The elastic support portion 70 is composed of a pair of spring portions 71. The pair of spring portions 71 is composed of a spring portion 71 on one side in the X direction and a spring portion 71 on the other side in the X direction. The X direction is the longitudinal direction of the first shield member 21. The spring portion 71 on one side in the X direction and the spring portion 71 on the other side in the X direction have a symmetrical structure with respect to the X direction. Hereinafter, when no particular distinction is made, they will be simply referred to as spring portions 71.

[0082] The spring portion 71 includes a pair of spring pieces 72. The pair of spring pieces 72 is composed of a spring piece 72 on one side in the Y direction and a spring piece 72 on the other side in the Y direction. The pair of spring pieces 72 have shapes that are symmetrical with respect to the Y direction. Hereinafter, unless otherwise specified, they will be simply referred to as spring pieces 72.

[0083] The spring piece 72 connects the fixed part 50 and the movable part 60. Specifically, the spring piece 72 connects the cylindrical part 51 of the fixed part 50 and the inner cylindrical part 61 of the movable part 60. More specifically, the spring piece 72 connects the second wall part 51 b of the fixed part 50 and the second inner wall part 61 b ​​of the movable part 60.

[0084] The spring piece 72 is provided at a position overlapping the inner cylindrical portion 61 of the movable portion 60 when viewed from above.

[0085] The spring piece 72 has a one-side extending portion 72a extending in a direction away from the starting end of the spring piece 72 (inward in the X direction), a other-side extending portion 72b extending in a direction approaching the terminal end of the spring piece 72 (outward in the X direction), and a folded portion 72c connecting the one-side extending portion 72a and the other-side extending portion 72b. The folded portion 72c extends in a substantially arc shape.

[0086] The one-side extending portion 72a extends in a direction sloping upward away from the starting end of the spring piece 72 (inward in the X direction), while the other-side extending portion 72b extends in a direction sloping upward toward the terminal end of the spring piece 72 (outward in the X direction).

[0087] As shown in Figure 6, the fixed part 50 has a first fixed-side contact part 56 and a pair of second fixed-side contact parts 57. The first fixed-side contact part 56 has a first bent part 56a bent inward (inward in the X direction). Each of the pair of second fixed-side contact parts 57 has a second bent part 57a bent inward (inward in the X direction). On the other hand, the movable part 60 has a movable-side contact part 66. The movable-side contact part 66 has a bent part 66a bent inward (inward in the X direction).

[0088] When the movable part 60 is displaced downward (in the -Z direction), the movable-side contact part 66 comes into contact with the first fixed-side contact part 56. This prevents the movable part 60 from being displaced excessively downward. As a result, the first shield member 21 is provided with downward direction restriction mechanisms 56, 66 that restrict the movable part 60 from being displaced excessively in the direction (in the -Z direction) approaching the first attachment object 91 (attachment object).

[0089] When the movable part 60 is displaced in the Y direction, the movable-side contact part 66 comes into contact with one of the pair of second fixed-side contact parts 57. This restricts the movable part 60 from being displaced excessively in the Y direction. Thus, the first shield member 21 is provided with Y-direction restriction mechanisms 57, 66 that restrict the movable part 60 from being displaced excessively in the Y direction relative to the fixed part 50.

[0090] In particular, since each abutment portion 56, 57, 66 has a bent portion 56a, 57a, 66a, even if the movable portion 60 is displaced in the X direction relative to the fixed portion 50, the movable side abutment portion 66 can be reliably abutted against the fixed side abutment portions 56, 57.

[0091] 6, the elastic support member 70 is not deformed, and the movable member 60 is not displaced downward. Therefore, even if the movable member 60 is displaced in the Y direction from this state, the movable-side contact member 66 does not come into contact with the second fixed-side contact member 57. However, in the connected state assumed in this embodiment, the movable member 60 is displaced downward, and a portion of the movable-side contact member 66 is housed between the pair of second fixed-side contact members 57.

[0092] (Second shielding member 22) The second shielding member 22 is made by subjecting a single piece of conductive plate material to processes such as punching and bending, etc. Therefore, one part of the second shielding member 22 is connected to another part without any joint therebetween.

[0093] The second shield member 22 has a cylindrical shape (specifically, a rectangular cylindrical shape) and is substantially symmetrical in both the X direction and the Y direction.

[0094] 4, a joint 22h is formed at one side in the Y direction (+Y direction side) of the cylindrical second shield member 22, where ends of the plates constituting the second shield member 22 are joined together. The joint 22h is provided at the center of the second shield member 22 in the X direction.

[0095] The second shielding member 22 has a fixing portion 80 that is fixed to a second substrate 92 that serves as a "second attachment object." Unlike the first shielding member 21, the second shielding member 22 does not have a movable portion or an elastic support portion.

[0096] (Fixed Part 80 ) The fixed part 80 includes a fixed shield part 81 .

[0097] The fixed shield part 81 includes a pair of first wall parts 81a facing each other in the X direction and a pair of second wall parts 81b facing each other in the Y direction. The first wall parts 81a are wall parts extending in the Y direction and are flat plates with their thickness direction facing the X direction. The second wall parts 81b are wall parts extending in the X direction and are flat plates with their thickness direction facing the Y direction. As a result, the fixed shield part 81 is formed in a cylindrical shape (specifically, a rectangular cylindrical shape). The fixed shield part 81 is sometimes referred to as the cylindrical part 81. The first wall parts 81a and the second wall parts 81b are connected via a curved part extending in the vertical direction. As a result, the cylindrical part 81 is completely cylindrical.

[0098] The fixing portion 80 includes a plurality of connecting portions 82 a, 82 b, and 82 c. Each of the plurality of connecting portions 82 a, 82 b, and 82 c is joined by soldering to a pad (not shown) formed on the upper surface of the first substrate 91. This attaches the second shielding member 22 to the second substrate 92 and electrically connects the second shielding member 22 and the second substrate 92 together.

[0099] The multiple connection portions 82a, 82b, 82c include multiple first connection portions 82a protruding from the first wall portion 81a. The multiple connection portions 82a, 82b, 82c include multiple second connection portions 82b protruding from the second wall portion 81b. The multiple connection portions 82a, 82b, 82c include multiple (four) third connection portions 82c whose plate thickness directions are oriented in the up-down direction. The third connection portions 82c are connected to the second wall portion 81b via curved portions.

[0100] (Opposite Plate Portions 84a, 84b) The fixing portion 80 includes a plurality of opposed plate portions 84a, 84b.

[0101] The multiple opposing plate portions 84a, 84b are composed of multiple first opposing plate portions 84a provided at positions corresponding to the first wall portion 81a and multiple second opposing plate portions 84b provided at positions corresponding to the second wall portion 81b.

[0102] The opposing plate portions 84a and 84b are flat plates whose thickness direction faces the Z direction. The opposing plate portions 84a and 84b are connected to the cylindrical portion 81 via bent portions 85a and 85b that are bent at approximately 90 degrees.

[0103] The first opposing plate portion 84a is located on the outer side in the Y direction relative to the fixed shield portion 81. The second opposing plate portion 84b is located on the outer side in the X direction relative to the fixed shield portion 81. In other words, the multiple opposing plate portions 64b are located on the outer side relative to the fixed shield portion 81. The outer side here means the side away from the objects 11 and 12 to be shielded.

[0104] The second opposing plate portion 84b comes into contact with the contact portion 64b (opposing plate portion 64b) of the first shield member 21. That is, the second opposing plate portion 84b functions as the contact portion 84b of the second shield member 22.

[0105] The lower surface of the second opposing plate portion 84b contacts the upper surface of the opposing plate portion 64b of the first shield member 21. Because the plate surface is the contact point, it is easy to apply plating to the contact point. The lower surface of the second opposing plate portion 84b is a flat surface whose normal direction faces downward. The second opposing plate portion 84b is sometimes referred to as the contact flat surface portion 84.

[0106] The second opposing plate portion 84b comes into contact with the opposing plate portion 64b of the first shield member 21 in a contact area extending in the X direction. Specifically, this contact area is a rectangular contact area with the X direction as the longitudinal direction and the Y direction as the lateral direction.

[0107] The first opposing plate portion 84a is configured not to come into contact with the first shield member 21. The first opposing plate portion 84a faces the first folded portion 63a in the up-down direction.

[0108] <Operation and Effect> Next, the operation and effect of this embodiment will be described.

[0109] 1 and 2 , in this embodiment, the pair of shield members 21, 22 includes a first shield member 21 attached to a first attachment object 91 and a second shield member 22 attached to a second attachment object 92. The first shield member 21 and the second shield member 22 face each other in the up-down direction (Z direction). The first shield member 21 has first shield portions 61, 62 that shield the objects to be shielded 11, 12 from a direction perpendicular to the up-down direction (Z direction), and the second shield member 22 has a second shield portion 81 that shields the objects to be shielded 11, 12 from a direction perpendicular to the up-down direction (Z direction). Therefore, the first shield portions 61, 62 and the second shield portion 81 can shield the objects to be shielded 11, 12 from a direction perpendicular to the up-down direction (Z direction).

[0110] However, a gap may occur in the vertical direction (Z direction) between the first shield parts 61, 62 and the second shield part 81. This gap reduces the shielding performance. Therefore, in this embodiment, as shown in FIGS. 1 and 2 , the pair of shielding members 21, 22 includes a cover part 87b that closes the gap between the first shield parts 61, 62 and the second shield part 81 from a direction perpendicular to the vertical direction. This prevents the shielding performance from being reduced, and the pair of shielding members 21, 22 with high shielding performance can be achieved.

[0111] 1 and 2, in this embodiment, the first shielding member 21 has a first contact portion 64b, and the second shielding member 22 has a second contact portion 84b. The first contact portion 64b and the second contact portion 84b are in contact with each other. Therefore, the first shielding member 21 and the second shielding member 22 can be electrically connected to each other.

[0112] 1 and 2, at least one of the first contact portion 64b and the second contact portion 84b is a flat contact portion 84b that is perpendicular to the up-down direction. Therefore, even if the first shielding member 21 and the second shielding member 22 are misaligned in the direction perpendicular to the up-down direction, the two can be electrically connected to each other.

[0113] 2, in this embodiment, the cover portion 87b extends from the contact flat surface portion 84b, so that the cover portion 87b can effectively cover the gap formed in the vicinity of the contact flat surface portion 84b.

[0114] 1 , in this embodiment, the first shield member 21 includes a fixed portion 50 that is fixed to the first attachment object 91, and a movable portion 60 that is displaceable in the up-down direction (Z direction) relative to the fixed portion 50. The movable portion 60 has movable shield portions 61, 62 that serve as the first shield portions 61, 62. This allows for adjustment to any misalignment in the up-down direction (Z direction) between the first shield member 21 and the second shield member 22.

[0115] 4, in this embodiment, the first shield member 21 includes an elastic support portion 70 that supports the movable portion 60 so that the movable portion 60 can be displaced. The elastic support portion 70 has a spring piece 72 that connects the fixed portion 50 and the movable portion 60. Therefore, the movable portion 60 can be elastically displaced.

[0116] However, if the cover portion 87b is provided on the first shielding member 21, the structure of the first shielding member 21 provided with the spring pieces 72 becomes even more complicated, which may make it impossible to realize a structure that ensures shielding performance. Therefore, in this embodiment, as shown in Fig. 4, the second shielding member 22 includes the cover portion 87b. In other words, the cover portion 87b is provided on the second shielding member 22. This makes it possible to prevent the structure of the first shielding member 21 from becoming too complicated.

[0117] Although the preferred embodiments of the connector of the present disclosure have been described above, the present disclosure is not limited thereto.

[0118] For example, in the above embodiment, the movable part is displaceable relative to the fixed part in either the up-down direction or in two directions perpendicular to the up-down direction, and is also displaceable so as to rotate slightly around an axis in the up-down direction or an axis perpendicular to the up-down direction, etc. However, the movable part of the present disclosure may be displaceable in any way relative to the fixed part.
