Description

Shielding member and shielding member pair

[0001] The present disclosure relates to a shield member and 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 shielding member and a pair of shielding members with high shielding performance.

[0005] The shielding member of the first aspect is a shielding member for shielding an object to be shielded, and the shielding member has a contact portion that contacts the object to be contacted, and the contact portion is configured to contact the object to be contacted in a contact area extending in the longitudinal direction of the shielding member.

[0006] In this aspect, the shielding member has a contact portion that comes into contact with the contact object, thereby electrically connecting the shielding member and the contact object.

[0007] However, when the contact portion is composed of multiple convex contact portions arranged in the longitudinal direction of the shielding member (shield longitudinal direction), a long, narrow gap is formed between adjacent convex contact portions in the shield longitudinal direction. This gap reduces shielding performance. While it is possible to narrow the spacing between adjacent convex contact portions by increasing the number of convex contact portions, it is difficult to uniformly protrude the multiple convex contact portions, resulting in some convex contact portions not in contact. Therefore, in this embodiment, the contact portion is configured to contact the contact object in a contact region extending in the longitudinal direction of the shielding member. Therefore, compared to an embodiment in which the contact portion is composed of multiple convex contact portions arranged in the longitudinal direction of the shielding member (shield longitudinal direction), the formation of a gap extending in the shield longitudinal direction between the shielding member and the contact object can be suppressed. As a result, a shielding member with high shielding performance can be realized.

[0008] In the embodiment described below, a plurality of (two) contact portions are arranged in the longitudinal direction, and the sum of the longitudinal lengths of the contact regions of the plurality of contact portions is 60% or more of the longitudinal dimension of the shielding member. However, this aspect is not limited to this. In the embodiment described below, the shielding member has a movable portion, and the movable portion has a contact portion. In the embodiment described below, the contact object that the contact portion comes into contact with is another shielding member (second shielding member). In the embodiment described below, the shielding member has a movable portion. However, the shielding member of this aspect is not limited to this. In the embodiment described below, the connector pair that is the shielding object includes a floating connector, but this aspect is not limited to this. The connector pair that is the shielding object of this aspect does not have to include a floating connector. In the embodiment described below, the fixing portion is directly fixed to the attachment object (first substrate). However, the fixing portion of this aspect is not limited to this. The fixing portion may be indirectly fixed to the attachment object via the shielding object. In the embodiment described below, the contact portion is a flat contact portion perpendicular to the direction of connection with the contact object. However, the contact portion in this embodiment is not limited to this and may be any contact portion that extends in a direction perpendicular to the direction of connection with the contact object.

[0009] In a shield member according to a second aspect, in the first aspect, the contact portion is a flat contact portion that is perpendicular to a direction of connection with the contact object.

[0010] In this aspect, the contact portion is a flat contact portion perpendicular to the direction of connection with the contact object, so that an appropriate contact state can be achieved even if the contact object is displaced in the direction perpendicular to the direction of connection.

[0011] The shielding member of the third aspect is the shielding member of the first or second aspect, which comprises a fixed portion fixed to an attachment object and a movable portion displaceable relative to the fixed portion in the direction of connection with the contact object, and the movable portion has the contact portion.

[0012] In this aspect, the shield member includes a fixed portion that is fixed to the attachment object and a movable portion that is displaceable relative to the fixed portion in a connection direction with the contact object. The movable portion has a contact portion. Therefore, by displacing the movable portion in the connection direction, it is possible to absorb positional misalignment of the contact object in the connection direction.

[0013] The shielding member of the fourth aspect is the shielding member of the first or second aspect, which comprises a fixed portion that is fixed to an object to be attached and a movable portion that can tilt longitudinally relative to the fixed portion, and the movable portion has the contact portion.

[0014] However, if the contact portion is configured to contact the contact object in a contact region extending in the longitudinal direction of the shield member, there is a risk that the contact portion and the contact object will not be in proper contact if the contact object is tilted in the longitudinal direction relative to the desired state. Therefore, in this aspect, the movable portion having the contact portion is tiltable in the longitudinal direction relative to the fixed portion. Therefore, even if the contact object is tilted in the longitudinal direction relative to the desired state, the contact portion can be in proper contact with the contact object.

[0015] A fifth aspect of the shielding member is the second aspect, in which the shielding member includes a shielding portion that shields the shielded object from a direction perpendicular to the connection direction with the contact object, the shielding portion having a wall portion whose thickness direction faces in a direction perpendicular to the connection direction with the contact object, and the contact plane portion is connected to the wall portion via a curved portion that extends in a direction perpendicular to the connection direction with the contact object.

[0016] In this aspect, the shielding member includes a shielding portion that shields the object to be shielded from a direction perpendicular to the connection direction with the contact object. The shielding portion has a wall portion whose thickness direction is oriented in a direction perpendicular to the connection direction with the contact object. Therefore, the wall portion can shield the object to be shielded from a direction perpendicular to the connection direction with the contact object.

[0017] In this aspect, the flat contact portion is connected to the wall portion via a curved portion extending in a direction perpendicular to the connection direction, thereby realizing a shield member having a wall portion and a flat contact portion with a simple structure.

[0018] A shielding member according to a sixth aspect is the shielding member of the third or fourth aspect, wherein the movable portion does not have a portion fixed to the object to be shielded.

[0019] 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. As a result, the structure of the shielding member can be simplified.

[0020] 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.

[0021] A shielding member according to a seventh aspect is the shielding member of the third or fourth aspect, wherein the movable portion does not have a portion that physically engages with the object to be shielded.

[0022] 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.

[0023] A shielding member according to an eighth aspect is any one of the first to fifth aspects, wherein the shielding member does not have a portion that is fixed to the object to be shielded.

[0024] In this aspect, the shielding member does not have a portion that is fixed to the object to be shielded. Therefore, it is not necessary to provide the shielding member with a structure for fixing it to the object to be shielded. As a result, the structure of the shielding member can be simplified.

[0025] 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.

[0026] The shielding member of the ninth aspect is the third or fourth aspect, wherein the movable part does not have a part fixed to the object to be shielded, and the fixed part has a part fixed to the object to be shielded.

[0027] 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.

[0028] The shielding member according to a tenth aspect is any one of the first to ninth aspects, wherein the contact portion is configured so that contact pressure due to contact with the contact object occurs in the direction of connection with the contact object.

[0029] In this aspect, the contact portion is configured so that contact pressure due to contact with the contact object occurs in the connection direction with the contact object. Therefore, by appropriately controlling the position of the contact portion in the connection direction, an appropriate contact pressure can be achieved.

[0030] The contact pressure here refers to a normal force generated at the contact point. In the embodiment described below, the contact portion is a flat contact portion perpendicular to the connection direction with the contact object. However, the contact portion in this aspect is not limited to this. For example, the contact object may have a flat contact portion perpendicular to the connection direction with the contact object, and the contact portion may be configured to come into contact with this flat contact portion. In the embodiment described below, the shield member has a movable portion that can be displaced in the connection direction, and the contact portion is formed on the movable portion. (Therefore, the movable portion can be easily displaced in the connection direction by contact pressure.) However, this aspect is not limited to this.

[0031] The pair of shielding members according to the eleventh aspect is a pair of shielding members for shielding an object to be shielded, and the pair of shielding members comprises a first shielding member attached to a first attachment object which is a first substrate, and a second shielding member attached to a second attachment object which is a second substrate, wherein the first shielding member has a first contact portion that contacts the second shielding member, and the first contact portion is configured to contact the second shielding member in a contact region extending in the longitudinal direction of the first shielding member.

[0032] When a shielding target disposed between a first substrate and a second substrate is shielded solely by a shielding member (first shielding member) attached to the first substrate, the first shielding member's contact target is the second substrate. Therefore, to form a contact area extending in the longitudinal direction of the shielding member, it is necessary to form contact portions (pads) extending in the longitudinal direction of the shielding member on the surface of the second substrate. However, this reduces the degree of freedom in the wiring layout of the second substrate. Therefore, this aspect relates to a shielding member pair for shielding a shielding target. The shielding member pair includes a first shielding member attached to a first mounting target, which is the first substrate, and a second shielding member attached to a second mounting target, which is the second substrate. The first shielding member has a first contact portion that contacts the second shielding member, and the first contact portion is configured to contact the second shielding member in a contact area extending in the longitudinal direction of the first shielding member. Therefore, since it is not necessary to form contact portions (pads) extending in the longitudinal direction of the shielding member on the surface of the second substrate, the degree of freedom in the wiring layout of the second substrate can be ensured.

[0033] In the embodiment described below, the first shielding member has a connecting portion, and the first shielding member is attached to the first substrate by joining the connecting portion to the first substrate. However, the first shielding member of this embodiment is not limited to this. The first shielding member may be attached to the object to be shielded, and the object to be shielded may be attached to the first substrate, thereby attaching the first shielding member to the first substrate. In other words, the first shielding member does not have to have a connecting portion. The same applies to the second shielding member.

[0035] Preferred embodiments of the present disclosure will be described below.

[0036] 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.

[0037] 1 and 2 show a shield structure 100 according to an embodiment.

[0038] The shield structure 100 includes attachment objects 91 and 92 , electronic components 11 and 12 , and shields 21 and 22 .

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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 that is fixed to a first attachment object 91, and a movable housing 34 that is displaceable relative to the fixed housing 33. The movable housing 34 is displaceable in any of the X, Y, and Z directions, as well as directions oblique to these directions.

[0043] 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.

[0044] 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.

[0045] 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 ).

[0046] 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.

[0047] 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).

[0048] 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).

[0049] (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.

[0050] (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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] (Fixed Part 50 ) The fixed part 50 includes a fixed shield part 51 .

[0055] 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.

[0056] 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.

[0057] 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.

[0058] The plurality of connection portions 52a, 52b, 52c includes 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.

[0059] 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.

[0060] 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 where a part near the lower edge of the fixed shield part 51 is cut out. 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.

[0061] 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.

[0062] (Moving Part 60) The moving part 60 is cylindrical (specifically, rectangular cylindrical).

[0063] The movable portion 60 includes movable shield portions 61 and 62 .

[0064] The movable shield parts 61 and 62 each include an inner cylindrical part 61 and an outer cylindrical part 62 disposed outside the inner cylindrical part 61 .

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] (Opposite Plate Portions 64b) The movable portion 60 has a plurality of (four) opposed plate portions 64b.

[0072] 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.

[0073] The opposing plate portion 64b is a flat plate with its thickness oriented in the up-down direction. The opposing plate portion 64b is substantially rectangular with its longitudinal direction in the X direction and its lateral direction in the Y direction. The opposing plate portion 64b is connected to the inner cylindrical portion 61 via a bent 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] (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.

[0079] 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.

[0080] 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.

[0081] The spring piece 72 is provided at a position overlapping the inner cylindrical portion 61 of the movable portion 60 when viewed from above.

[0082] 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.

[0083] 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).

[0084] 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).

[0085] 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).

[0086] 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.

[0087] 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.

[0088] 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.

[0089] (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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] (Fixed Part 80 ) The fixed part 80 includes a fixed shield part 81 .

[0094] 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.

[0095] 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.

[0096] 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.

[0097] (Opposite Plate Portions 84a, 84b) The fixing portion 80 includes a plurality of opposed plate portions 84a, 84b.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] <Operation and Effect> Next, the operation and effect of this embodiment will be described.

[0106] In this embodiment, the shield member 21 has a contact portion 64b that comes into contact with the contact object 22. Therefore, the shield member 21 and the contact object 22 can be electrically connected to each other.

[0107] However, if the contact portion 64b is composed of multiple convex contact portions arranged in the longitudinal direction (X direction) of the shield member 21, a long, narrow gap will be formed between adjacent convex contact portions in the longitudinal direction of the shield. This gap will result in a decrease in shielding performance. While it is possible to narrow the spacing between adjacent convex contact portions by increasing the number of convex contact portions, it is difficult to uniformly protrude the multiple convex contact portions, resulting in some of the convex contact portions being out of contact. Therefore, in this embodiment, the contact portion 64b is configured to contact the contact object 22 in a contact region extending in the longitudinal direction (X direction) of the shield member 21. Therefore, compared to an embodiment in which the contact portion 64b is composed of multiple convex contact portions arranged in the longitudinal direction (X direction) of the shield member 21, the formation of a gap extending in the longitudinal direction (X direction) of the shield between the shield member 21 and the contact object 22 can be suppressed. As a result, a shield member 21 with high shielding performance can be realized.

[0108] In this embodiment, the contact portion 64b is a flat contact portion 64b that is perpendicular to the connection direction (Z direction) with the contact object 22. Therefore, even if the contact object 22 is displaced in the direction perpendicular to the connection direction (Z direction), an appropriate contact state can be achieved.

[0109] In this embodiment, the shield member 21 includes a fixed portion 50 that is fixed to the attachment object 91, and a movable portion 60 that is displaceable in the connection direction (Z direction) relative to the fixed portion 50. The movable portion 60 has a contact portion 64b. Therefore, by displacing the movable portion 60 in the connection direction (Z direction), it is possible to absorb positional deviation of the contact object 22 in the connection direction (Z direction).

[0110] However, if the contact portion 64b is configured to contact the contact object 22 in a contact region extending in the longitudinal direction (X direction) of the shield member 21, there is a risk that the contact portion 64b and the contact object 22 will not be in proper contact with each other if the contact object 22 is tilted in the longitudinal direction (X direction) with respect to a desired state. Therefore, in this embodiment, the movable part 60 having the contact portion 64b is tiltable in the longitudinal direction (X direction) with respect to the fixed part 50. Therefore, even if the contact object 22 is tilted in the longitudinal direction (X direction) with respect to a desired state, it is possible to achieve a proper contact state between the contact portion 64b and the contact object 22.

[0111] In this embodiment, the shield member 21 includes shield sections 61 and 62 that shield the objects 11 and 12 from a direction perpendicular to the connection direction (Z direction). The shield sections 61 and 62 have wall sections 61 whose thickness direction is oriented in a direction perpendicular to the connection direction. Therefore, the wall sections 61 can shield the objects 11 and 12 from a direction perpendicular to the connection direction (Z direction).

[0112] In this embodiment, the flat contact portion 64b is connected to the wall portion 61 via a curved portion 65b extending in a direction perpendicular to the connection direction (Z direction). Therefore, the shield member 21 including the wall portion 61 and the flat contact portion 64b can be realized with a simple structure.

[0113] Incidentally, when shielding objects 11 and 12 arranged between a first substrate 91 and a second substrate 92 using only a shielding member 21 (first shielding member 21) attached to the first substrate 91, the contact object of the first shielding member 21 is the second substrate 92. Therefore, in order to form a contact area extending in the longitudinal direction (X direction) of the shielding member 21, it is necessary to form contact portions (pads) extending in the longitudinal direction (X direction) of the shielding member 21 on the surface of the second substrate 92. However, this reduces the degree of freedom in the wiring layout of the second substrate 92. Therefore, this embodiment relates to a pair of shielding members 21 and 22 for shielding the shielding objects 11 and 12. The pair of shielding members 21 and 22 includes a first shielding member 21 attached to the first attachment object 91, which is the first substrate 91, and a second shielding member 22 attached to the second attachment object 92, which is the second substrate 92. The first shielding member 21 has a first contact portion 64b that comes into contact with the second shielding member 22, and the first contact portion 64b is configured to come into contact with the second shielding member 22 in a contact region that extends in the longitudinal direction (X direction) of the first shielding member 21. Therefore, there is no need to form a contact portion (pad) that extends in the longitudinal direction (X direction) of the shielding member 21 on the surface of the second substrate 92, and therefore the degree of freedom in the wiring layout of the second substrate 92 can be ensured.

[0114] Although the preferred embodiments of the present disclosure have been described above, the present disclosure is not limited thereto.
