Description

Shielding material

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

[0002] Patent Document 1 discloses a shielding member.

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

[0004] The above-mentioned shield member does not have a movable shield portion that is displaceable relative to the attachment object (substrate) to which the shield member is attached.

[0005] An object of the present disclosure is to provide a shield member that includes a movable shield portion and has highly flexible elastic support portions that elastically support the movable shield portion.

[0006] The shielding member of the first aspect is a shielding member for shielding an object to be shielded, and comprises a fixed portion fixed to the object to be attached, a movable portion displaceable relative to the fixed portion, and an elastic support portion displaceably supporting the movable portion, wherein the movable portion has a movable shield portion that shields the object to be shielded from a direction perpendicular to the up-down direction, and the elastic support portion has a spring piece connecting the fixed portion and the movable portion, and the spring piece has a first direction extending portion that extends in a first direction that is perpendicular to the up-down direction, and a second direction extending portion that extends in a second direction that is perpendicular to the up-down direction and different from the first direction.

[0007] In this aspect, the shielding member includes a fixed portion fixed to the attachment object, a movable portion displaceable relative to the fixed portion, and an elastic support portion displaceably supporting the movable portion. The movable portion has a movable shield portion that shields the attachment object from a direction perpendicular to the up-down direction. Therefore, the attachment object can be shielded by the movable shield portion that is displaceable relative to the attachment object.

[0008] In this embodiment, the elastic support member has a spring piece connecting the fixed portion and the movable portion. The spring piece has a first-direction extending portion extending in a first direction perpendicular to the vertical direction and a second-direction extending portion extending in a second direction perpendicular to the vertical direction but different from the first direction. This makes it easier to lengthen the spring piece compared to an embodiment in which the spring piece extends in only one of the directions perpendicular to the vertical direction. As a result, a shield member with a highly flexible elastic support member can be realized.

[0009] 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 be directed toward the direction of gravity. In the embodiment described below, the second direction is perpendicular to the first direction. However, the second direction in this embodiment is not limited to this. The second direction in this embodiment may be oblique to the first direction. In the embodiment described below, the first direction coincides with the short-side direction of the shield member, and the second direction coincides with the long-side direction of the shield member. However, this embodiment is not limited to this. The first direction may coincide with the long-side direction of the shield member, and the second direction may coincide with the short-side direction of the shield member. In the embodiment described below, the movable shield section is configured to shield an object from four mutually perpendicular directions perpendicular to the vertical direction. However, the movable shield section in this embodiment is not limited to this. In the embodiment described below, the movable shield section has one or more wall sections whose thickness direction is perpendicular to the vertical direction. However, the movable shield section in this embodiment is not limited to this. For example, the thickness direction of the wall portion of the movable shield portion of this embodiment may be inclined with respect to a direction perpendicular to the vertical direction. Note that in the embodiment described below, the object to be shielded is a connector pair whose connection direction is the vertical direction. However, this embodiment is not limited to this. In this embodiment, the object to be shielded may be a connector pair whose connection direction is a direction other than the vertical direction. Also, in this embodiment, the object to be shielded does not have to be a connector pair. Note that in the embodiment described below, the shielding member is made by performing punching, bending, or the like on a single conductive plate material. Therefore, one portion of the first shielding member 21 is connected to another portion without a joint. Therefore, for example, the movable portion and the spring pieces are formed from the same single plate material. (In other words, the movable portion and the spring pieces are connected without a joint.) However, this embodiment is not limited to this. The movable portion and the spring pieces may be formed separately and then joined to each other. Note that in the embodiment described below, the shielding member does not have a portion physically connected to the object to be shielded, but the shielding member of this embodiment is not limited to this.The shielding member of this aspect may have a portion fixed to the object to be shielded. The shielding member of this aspect may also have a portion physically associated with the object to be shielded (excluding the fixed portion). Note that in the embodiment described below, the connector pair that is the object to be shielded includes a floating connector, but this aspect is not limited to this. The connector pair that is the object to be shielded of this aspect does not have to include a floating connector. Note that in the embodiment described below, a contact portion of the movable portion contacts the contact object (second substrate), thereby electrically connecting the contact object and the shielding member. However, this aspect is not limited to this. The contact object and the shielding member may contact each other but not be electrically connected. Also, the movable portion may not have a contact portion, and a contact object may not be assumed. Note that in the embodiment described below, the fixed portion is directly fixed to the object to be attached (first substrate). However, the fixed portion of this aspect is not limited to this. The fixed portion may be indirectly fixed to the object to be attached via the object to be shielded. In the embodiments described below, the direction in which the movable part can be displaced relative to the fixed part includes the up-down direction. However, this aspect is not limited to this. The direction in which the movable part can be displaced relative to the fixed part does not have to include the up-down direction. In other words, the movable part may not be displaceable in the up-down direction relative to the fixed part. In the embodiments described below, the movable part can be displaced relative to the fixed part in either the up-down direction or two directions perpendicular to the up-down direction, and can also be displaced 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. The movable part of this aspect may be displaceable in some way relative to the fixed part.

[0010] In the shielding member of the second aspect, in the first aspect, the second direction extending portion has a second direction one-side extending portion extending to one side in the second direction, a second direction other-side extending portion extending to the other side in the second direction, and a folded portion connecting the second direction one-side extending portion and the second direction other-side extending portion, and the second direction one-side extending portion and the second direction other-side extending portion are aligned in the vertical direction.

[0011] In this aspect, the second-direction extending portion has a second-direction one-side extending portion extending to one side in the second direction, a second-direction other-side extending portion extending to the other side in the second direction, and a folded-back portion connecting the second-direction one-side extending portion and the second-direction other-side extending portion. Therefore, compared to an aspect in which the second-direction extending portion extends only to one side or the other side in the second direction, it is possible to lengthen the spring piece while avoiding an increase in size of the spring piece in the second direction.

[0012] In this aspect, the second direction one-side extending portion and the second direction other-side extending portion are aligned in the up-down direction, which prevents the spring piece from becoming large in size in the directions perpendicular to the up-down direction and the second direction.

[0013] In the embodiment described below, the first direction extending portion has a first direction one-side extending portion that extends to one side in the first direction and a first direction other-side extending portion that extends to the other side in the first direction. However, the first direction extending portion of this embodiment may have a first direction one-side extending portion and not have a first direction other-side extending portion. In the embodiment described below, the folded portion extends in a substantially arc shape. However, the folded portion of this embodiment is not limited to this.

[0014] The shielding member of the third aspect is the second aspect, wherein the first direction extending portion has a first direction one-side extending portion extending to one side in the first direction and a first direction other-side extending portion extending to the other side in the first direction, and the first direction one-side extending portion and the first direction other-side extending portion are aligned in the vertical direction.

[0015] In this aspect, the first-direction extending portion has a first-direction-one-side extending portion that extends to one side in the first direction and a first-direction-other-side extending portion that extends to the other side in the first direction. Therefore, compared to an aspect in which the first-direction extending portion extends only to one side in the first direction or only to the other side in the first direction, the spring piece can be made longer while avoiding an increase in size of the spring piece in the first direction.

[0016] In this aspect, the first direction one-side extending portion and the first direction other-side extending portion are aligned in the up-down direction, which prevents the spring piece from becoming large in size in directions perpendicular to the up-down direction and the first direction.

[0017] The shield member according to the fourth aspect is any one of the first to third aspects, in which the movable shield portion has a first direction wall portion extending in a first direction and a second direction wall portion extending in a second direction.

[0018] In this aspect, the movable shield part has a first-direction wall part extending in a first direction and a second-direction wall part extending in a second direction. That is, the first-direction wall part of the movable shield part and the first-direction extending part of the spring piece extend in the same direction (first direction), and the second-direction wall part of the movable shield part and the second-direction extending part of the spring piece extend in the same direction (second direction). This allows the movable shield part and the spring piece to be arranged efficiently.

[0019] In the embodiment described below, the first direction wall portion is a wall portion whose thickness direction is perpendicular to the up-down direction. However, the first direction wall portion of this embodiment is not limited to this. For example, the thickness direction of the first direction wall portion may be inclined with respect to the direction perpendicular to the up-down direction. The same applies to the second direction wall portion.

[0020] The shield member according to the fifth aspect is any one of the first to third aspects, wherein the movable shield portion has a pair of first direction wall portions extending in a first direction and a pair of second direction wall portions extending in a second direction, the elastic support portion has a pair of spring portions, each of the pair of spring portions has a pair of the spring pieces, and for each of the spring pieces, one side in the first direction is on the outside in the first direction and one side in the second direction is on the inside in the second direction.

[0021] In this aspect, the movable shield portion has a pair of first-direction wall portions extending in a first direction and a pair of second-direction wall portions extending in a second direction. The elastic support portion has a pair of spring portions, each of which has a pair of spring pieces. For each spring piece, one side in the first direction is the outer side in the first direction, and one side in the second direction is the inner side in the second direction. This allows for efficient arrangement of multiple spring pieces.

[0022] The "outer side in the first direction" refers to the side away from the center of the shielding member in the first direction, and the "inner side in the second direction" refers to the side closer to the center of the shielding member in the second direction. In the embodiment described below, the first direction is the widthwise direction of the shielding member, and the second direction is the lengthwise direction of the shielding member. However, this aspect is not limited to this.

[0023] A shield member according to a sixth aspect is the shield member of any one of the first to fifth aspects, wherein the shield member includes a closing wall portion disposed inside or outside the elastic support portion.

[0024] However, when elastic support portions are formed, gaps tend to form around the elastic support portions. These gaps result in a decrease in shielding performance. Therefore, in this embodiment, the shielding member includes a closing wall portion disposed inside or outside the elastic support portions. This allows the closing wall portion to close any gaps that form around the elastic support portions. As a result, shielding performance can be improved.

[0025] Note that "inside" refers to the side approaching the object to be shielded, and "outside" refers to the side away from the object to be shielded. Note that in the embodiment described below, the closing wall portion is a component of the movable shield portion. Therefore, the closing wall portion is displaceable in response to deformation of the spring piece. However, the closing wall portion of this aspect is not limited to this and may be, for example, a component of the fixed portion. Note that in the embodiment described below, the closing wall portion is arranged outside the elastic support portion. However, the closing wall portion of this aspect may also be arranged inside the elastic support portion. Furthermore, the closing wall portion may also be arranged on both the inside and outside of the elastic support portion.

[0026] A shield member according to a seventh aspect is the shield member of any one of the first to fifth aspects, wherein the shield member includes a closing wall portion disposed outside the elastic support portion.

[0027] In this aspect, the shield member includes a closing wall portion disposed outside the elastic support portion. That is, the closing wall portion is disposed outside the elastic support portion. This protects the elastic support portion from contact with foreign objects, the operator's fingers, etc.

[0028] The shielding member of the eighth aspect is any of the first to fifth aspects, and the shielding member comprises a first closing wall portion arranged inside or outside the first direction extending portion, and a second closing wall portion arranged inside or outside the second direction extending portion.

[0029] In this aspect, the shield member includes a first closing wall portion disposed inside or outside the first direction extending portion and a second closing wall portion disposed inside or outside the second direction extending portion, thereby making it possible to close gaps that occur around the first direction extending portion and the second direction extending portion.

[0030] In the embodiment described below, the first closed wall portion and the second closed wall portion are separated, and a gap is formed between the first closed wall portion and the second closed wall portion. However, this embodiment is not limited to this, and the first closed wall portion and the second closed wall portion may be formed continuously.

[0031] The shielding member of the ninth aspect is any one of the first to fifth aspects, and the shielding member comprises a first closing wall portion arranged outside the first direction extending portion and a second closing wall portion arranged outside the second direction extending portion.

[0032] In this aspect, the shield member includes a first closing wall portion disposed outside the first direction extending portion and a second closing wall portion disposed outside the second direction extending portion. That is, the first closing wall portion and the second closing wall portion are disposed outside the first direction extending portion and the second direction extending portion. This protects the first direction extending portion and the second direction extending portion from contact with foreign objects, an operator's fingers, or the like.

[0033] A tenth aspect of the present invention relates to the shield member of the eighth or ninth aspect, wherein the shield member includes a third closing wall portion that covers the gap between the first closing wall portion and the second closing wall portion.

[0034] However, if a gap is formed between the first and second closing walls, it will result in a decrease in shielding performance. Therefore, in this aspect, the shielding member includes a third closing wall that covers the gap between the first and second closing walls. This prevents the decrease in shielding performance.

[0035] The shield member according to an eleventh aspect is the shield member according to either the sixth or seventh aspect, wherein the closing wall portion is provided at a position corresponding to the entire elastic support portion.

[0036] In this aspect, the closing wall portion is provided at a position corresponding to the entire elastic support portion, thereby improving the shielding performance.

[0037] A shielding member according to a twelfth aspect is the shielding member of any one of the first to eleventh aspects, wherein the movable portion does not have a portion fixed to the object to be shielded.

[0038] 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.

[0039] 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.

[0040] A shielding member according to a thirteenth aspect is any one of the first to eleventh aspects, wherein the movable portion does not have a portion that physically engages with the object to be shielded.

[0041] 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.

[0042] A shielding member according to a fourteenth aspect is any one of the first to eleventh aspects, wherein the shielding member does not have a portion that is fixed to the object to be shielded.

[0043] 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.

[0044] 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.

[0045] The shielding member of the fifteenth aspect is any of the first to eleventh aspects, in which 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.

[0046] 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.

[0047] Fig. 1 is a cross-sectional view showing a shielding structure according to an embodiment; Fig. 2 is a cross-sectional view showing a shielding structure (connected state) according to an embodiment; Fig. 3 is an exploded perspective view of a connector pair including a floating connector; Fig. 4 is a perspective view of a first shielding member; Fig. 5 is a perspective view of the first shielding member as seen from another direction; Fig. 6 is an enlarged perspective view of the periphery of a spring piece of the first shielding member; Fig. 7 is a perspective view of a shielding member according to a modified example;

[0048] Preferred embodiments of the present disclosure will be described below.

[0049] 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.

[0050] 1 and 2 show a shield structure 100 according to an embodiment.

[0051] The shield structure 100 includes attachment objects 91 and 92, electronic components 11 and 12, and a shield 21.

[0052] In the shielding structure 100, electronic components 11 and 12, which are "shielded objects", are shielded by a shield 21. The electronic components 11 and 12 and the shield 21 are attached to objects 91 and 92, respectively.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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 ).

[0059] 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.

[0060] 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).

[0061] 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).

[0062] (Shield 21) The shield 21 is composed of only the first shield member 21.

[0063] (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.

[0064] 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.

[0065] 4, a joint 21h is formed at one side in the Y direction 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.

[0066] The first shielding member 21 has a fixed portion 50 fixed to the first substrate 91 as the "object to be attached", a movable portion 60 that is 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.

[0067] (Fixed Part 50 ) The fixed part 50 includes a fixed shield part 51 .

[0068] 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. Each first wall part 51a is a wall part extending in the Y direction and is a flat plate with its thickness direction facing the X direction. Each second wall part 51b is a wall part extending in the X direction and is a flat plate with its 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 part 51a and the second wall part 51b are connected via a curved part extending in the vertical direction. As a result, the cylindrical part 51 is completely cylindrical.

[0069] The fixing portion 50 includes a plurality of connecting portions 52 a, 52 c. Each of the plurality of connecting portions 52 a, 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.

[0070] The multiple connection portions 52a, 52c include multiple first connection portions 52a protruding from the first wall portion 51a. Each first connection portion 52a has a shape that protrudes downward from the lower edge of the first wall portion 51a. Multiple (two) first connection portions 52a are formed for each first wall portion 51a. Note that although the fixing portion 50 of this embodiment is not provided, the fixing portion may include multiple second connection portions protruding from the second wall portion 51b. In this case, the structure of the second connection portions may be the same as that of the first connection portions 52a.

[0071] The connecting portions 52 a, 52 c include four third connecting portions 52 c whose thickness directions are oriented in the up-down direction. The third connecting portions 52 c are connected to the second wall portion 51 b of the fixed shield part 51 via bent portions.

[0072] 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.

[0073] 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.

[0074] (Moving Part 60) The moving part 60 is cylindrical (specifically, rectangular cylindrical).

[0075] The movable portion 60 includes movable shield portions 61 and 62 .

[0076] 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 .

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] The first outer wall portion 62a and the second outer wall portion 62b are disposed outside the elastic support portion 70. As a result, the first outer wall portion 62a and the second outer wall portion 62b close the gap formed around the elastic support portion 70. The first outer wall portion 62a and the second outer wall portion 62b may be referred to as closing wall portions 62a, 62b.

[0082] 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.

[0083] When the movable portion 60 is in its initial position (see FIG. 1, when the elastic support portion 70 is not deformed), the lower end of the outer cylindrical portion 62 is located lower than the upper end of the cylindrical portion 51 .

[0084] (Resilient Contact Portions 64b) The movable portion 60 has a plurality of (four) resilient contact portions 64b.

[0085] The plurality of elastic contact portions 64b include a plurality (two) of elastic contact portions 64b on one side in the Y direction and a plurality (two) of elastic contact portions 64b on the other side in the Y direction. Hereinafter, when no particular distinction is made, they will be simply referred to as elastic contact portions 64b.

[0086] The elastic contact portion 64b extends from the inner cylindrical portion 61. Specifically, the elastic contact portion 64b is a portion that extends upward from the second inner wall portion 61b of the inner cylindrical portion 61 and is bent outward (outward in the Y direction).

[0087] The elastic contact portions 64b come into contact with the second substrate 92, which is the "contact object." This electrically connects the first shield member 21 and the second substrate 92. Specifically, each of the multiple elastic contact portions 64b comes into contact with a pad (not shown) formed on the lower surface of the second substrate 92.

[0088] Although not shown, the pad formed on the lower surface of the second substrate 92 has a larger contact area than the contact area between the pad and the elastic contact portion 64b of the first shielding member 21. Therefore, even if the movable portion 60 of the first shielding member 21 and the second substrate 92 are slightly misaligned in the XY plane, they can still be in contact with each other.

[0089] The elastic contact portion 64b comes into contact with the contact object (second substrate 92) so as to receive a downward force from the contact object (second substrate 92). This makes it easy to displace the movable portion 60 downward. Because the movable portion 60 is displaced elastically, the contact pressure is ensured by the elastic restoring force.

[0090] Second bent portions 63b are provided on one side in the Y direction and the other side in the Y direction of the elastic contact portion 64b.

[0091] (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.

[0092] 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.

[0093] 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 first wall part 51 a of the fixed part 50 and the first inner wall part 61 a of the movable part 60.

[0094] The spring piece 72 is provided at a position overlapping the inner cylindrical portion 61 of the movable portion 60 when viewed from above.

[0095] 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, a second-side extending portion 72b extending in a direction approaching the terminal end of the spring piece 72, and a folded portion 72c connecting the one-side extending portion 72a and the second-side extending portion 72b. The folded portion 72c extends in a substantially arc shape.

[0096] The one-side extending portion 72a extends in a direction sloping upward as it moves away from the starting end of the spring piece 72. The other-side extending portion 72b extends in a direction sloping upward as it moves closer to the terminal end of the spring piece 72.

[0097] The one-side extending portion 72a has a Y-direction extending portion 72a1 extending in the Y direction and an X-direction extending portion 72a2 extending in the X direction. The other-side extending portion 72b has a Y-direction extending portion 72b1 extending in the Y direction and an X-direction extending portion 72b2 extending in the X direction.

[0098] The Y-direction extending portion 72a1 of the one-side extending portion 72a and the Y-direction extending portion 72b1 of the other-side extending portion 72b are aligned in the vertical direction. Specifically, the Y-direction extending portion 72a1 of the one-side extending portion 72a and the Y-direction extending portion 72b1 of the other-side extending portion 72b overlap each other when viewed in the vertical direction.

[0099] The Y-direction extending portion 72a1 of the one-side extending portion 72a and the Y-direction extending portion 72b1 of the other-side extending portion 72b both extend in the Y direction (first direction) and correspond to the "first direction extending portions 72a1, 72b1." The Y-direction extending portion 72a1 of the one-side extending portion 72a corresponds to the "first direction one-side extending portion 72a1," and the Y-direction extending portion 72b1 of the other-side extending portion 72b corresponds to the "first direction other-side extending portion 72b1."

[0100] The X-direction extending portion 72a2 of the one-side extending portion 72a and the X-direction extending portion 72b2 of the other-side extending portion 72b are aligned in the vertical direction. Specifically, the X-direction extending portion 72a2 of the one-side extending portion 72a and the X-direction extending portion 72b2 of the other-side extending portion 72b overlap each other when viewed from the vertical direction.

[0101] The X-direction extending portion 72a2 of the one-side extending portion 72a and the X-direction extending portion 72b2 of the other-side extending portion 72b both extend in the X direction (second direction) and correspond to the "second-direction extending portions 72a2, 72b2." The X-direction extending portion 72a2 of the one-side extending portion 72a corresponds to the "second-direction one-side extending portion 72a2," and the X-direction extending portion 72b2 of the other-side extending portion 72b corresponds to the "second-direction other-side extending portion 72b2."

[0102] Fig. 2 shows a state in which the first connector 11 and the second connector 12 are connected. However, in the state shown in Fig. 2, the contact portion 31b of the first terminal 31 of the first connector 11 and the contact portion 41b of the second terminal 41 of the second connector 12 are in contact with each other, and the multiple elastic contact portions 64b of the movable portion 60 are in contact with the second board 92, but the movable portion 60 has not been displaced from its initial position.

[0103] Although the first connector 11 and the second connector 12 are normally connected in the state shown in Figure 2, the first connector 11 and the second connector 12 can be connected even more deeply. In other words, even if the distance between the first board 91 and the second board 92 is shorter than the distance shown in Figure 2, the connection state between the first connector 11 and the second connector 12 is maintained normally. In other words, the first connector 11 and the second connector 12 are configured to be normally connected even if there is some variation in the distance between the first board 91 and the second board 92. Although not shown, when the distance between the first board 91 and the second board 92 becomes shorter than the distance shown in Figure 2, the movable part 60 is pressed downward by the second board 92 at the multiple elastic contact parts 64b, and is elastically displaced downward from the initial position.

[0104] [Regarding Common Use of Shield] Next, common use of the shield will be described.

[0105] In the above embodiment, the shielding target of the shield 21 is the connector pair 11, 12 shown in Figures 1 and 2, but it may be a connector pair having a different structure. In other words, the first shielding member 21 as the shield 21 can be used to shield multiple types of connector pairs having different structures.

[0106] In particular, the first shield member 21 does not have a portion that is fixed to the connector pair 11, 12. Furthermore, the first shield member 21 does not have a portion that physically engages with the connector pair 11, 12. Therefore, there is little need to provide the shield 21 with a structure that corresponds to the structure of the connector pair 11, 12. As a result, it is easy to share the shield.

[0107] However, the shield can be shared even if the shielding material that constitutes the shield has a portion that is fixed to the object to be shielded. If the structure of the portion where the shielding material is fixed is made common between different types of connector pairs, the shield 21 can be shared.

[0108] However, the fact that the movable part 60 does not have a part that is fixed to the object to be shielded is advantageous in that the shielding member can be shared among a plurality of types of connectors.

[0109] By using a common shielding member for multiple types of connector pairs, it is possible to significantly reduce the cost of designing the shielding member, the cost of installing manufacturing equipment to manufacture the shielding member, etc. As a result, inexpensive shielding members and connectors with shielding members can be realized.

[0110] <Operation and Effect> Next, the operation and effect of this embodiment will be described.

[0111] In this embodiment, the shield member 21 includes a fixed portion 50 fixed to the attachment object 91, a movable portion 60 displaceable relative to the fixed portion 50, and an elastic support portion 70 displaceably supporting the movable portion 60. The movable portion 60 has movable shield portions 61, 62 that shield the shielding objects 11, 12 from a direction perpendicular to the up-down direction (Z direction). Therefore, the shielding objects 11, 12 can be shielded by the movable shield portions 61, 62 that are displaceable relative to the attachment object 91.

[0112] In this embodiment, the elastic support member 70 includes a spring piece 72 connecting the fixed portion 50 and the movable portion 60. The spring piece 72 includes first-direction extending portions 72a1 and 72b1 extending in a first direction (Y direction) perpendicular to the up-down direction (Z direction), and second-direction extending portions 72a2 and 72b2 extending in a second direction (X direction) perpendicular to the up-down direction (Z direction) but different from the first direction (Y direction). This makes it easier to elongate the spring piece 72 compared to a configuration in which the spring piece 72 extends in only one direction perpendicular to the up-down direction (Z direction). As a result, a shield member 21 having a highly flexible elastic support member 70 can be realized.

[0113] In addition, in the present embodiment, the second-direction extending portions 72a2, 72b2 each include a second-direction one-side extending portion 72a2 extending to one side in the second direction (inner side in the X direction), a second-direction other-side extending portion 72b2 extending to the other side in the second direction (outer side in the X direction), and a folded-back portion 72c connecting the second-direction one-side extending portion 72a2 and the second-direction other-side extending portion 72b2. Therefore, compared to an embodiment in which the second-direction extending portions 72a2, 72b2 extend only to one side in the second direction (inner side in the X direction) or only to the other side in the second direction (outer side in the X direction), the spring piece 72 can be made longer while avoiding an increase in size in the second direction (X direction).

[0114] In this embodiment, the second direction one-side extending portion 72a2 and the second direction other-side extending portion 72b2 are aligned in the vertical direction, which prevents the spring piece 72 from becoming large in size in the direction (Y direction) perpendicular to the vertical direction and the second direction (X direction).

[0115] In addition, in the present embodiment, the first-direction extending portions 72a1, 72b1 have a first-direction one-side extending portion 72a1 extending to one side in the first direction (outer side in the Y direction) and a first-direction other-side extending portion 72b1 extending to the other side in the first direction (inner side in the Y direction). Therefore, compared to an embodiment in which the first-direction extending portions 72a1, 72b1 extend only to one side in the first direction (outer side in the Y direction) or the other side in the first direction (inner side in the Y direction), it is possible to lengthen the spring piece 72 while avoiding an increase in the size of the spring piece 72 in the first direction (Y direction).

[0116] In this embodiment, the first direction one-side extending portion 72a1 and the first direction other-side extending portion 72b1 are aligned in the vertical direction, which prevents the spring piece 72 from becoming large in size in the direction (X direction) perpendicular to the vertical direction (Z direction) and the first direction (Y direction).

[0117] Furthermore, in this embodiment, the movable shield parts 61, 62 have first-direction wall parts 61a, 62a extending in a first direction (Y direction) and second-direction wall parts 61b, 62b extending in a second direction (X direction). That is, the first-direction wall parts 61a, 62a of the movable shield parts 61, 62 and the first-direction extending parts 72a1, 72b1 of the spring pieces 72 extend in the same direction (first direction (Y direction)), and the second-direction wall parts 61b, 62b of the movable shield parts 61, 62 and the second-direction extending parts 72a2, 72b2 of the spring pieces 72 extend in the same direction (second direction (X direction)). This allows the movable shield parts 61, 62 and the spring pieces 72 to be efficiently arranged.

[0118] In this embodiment, the movable shield parts 61, 62 have a pair of first-direction walls 61a, 62a extending in a first direction (Y direction) and a pair of second-direction walls 61b, 62b extending in a second direction (X direction). The elastic support part 70 has a pair of spring parts 71, each of which has a pair of spring pieces 72. For each spring piece 72, one side in the first direction (outside in the Y direction) is the outside in the first direction (outside in the Y direction), and one side in the second direction (inside in the X direction) is the inside in the second direction (inside in the X direction). This allows the multiple spring pieces 72 to be arranged efficiently.

[0119] However, when the elastic support portion 70 is formed, gaps tend to form around the elastic support portion 70. These gaps result in a decrease in shielding performance. Therefore, in this embodiment, the shield member 21 includes closing wall portions 62a, 62b disposed outside the elastic support portion 70. Therefore, the closing wall portions 62a, 62b can close the gaps that form around the elastic support portion 70. As a result, the shielding performance can be improved. Furthermore, the elastic support portion 70 can be protected from contact with foreign objects, the operator's fingers, etc.

[0120] In the present embodiment, the shield member 21 includes a first closing wall 62a disposed outside the first direction extending portions 72a1 and 72b1 and a second closing wall 62b disposed outside the second direction extending portions 72a2 and 72b2. This allows gaps around the first direction extending portions 72a1 and 72b1 and the second direction extending portions 72a2 and 72b2 to be blocked. This also protects the first direction extending portions 72a1 and 72b1 and the second direction extending portions 72a2 and 72b2 from contact with foreign objects, an operator's fingers, or the like.

[0121] However, if a gap is formed between the first closing wall 62a and the second closing wall 62b, the shielding performance will be reduced. Therefore, instead of this embodiment, as in the modified example shown in Figure 7, the shielding member 121 may be provided with a third closing wall 62c that covers the gap between the first closing wall 62a and the second closing wall 62b. In this case, the reduction in shielding performance can be prevented.

[0122] 7, the closing walls 62a and 62b are provided at positions corresponding to the entire elastic support portion 70. This can improve the shielding performance.

[0123] Furthermore, in this embodiment, the movable part 60 does not have any portion that is fixed to the objects to be shielded 11, 12. Therefore, it is not necessary to provide the movable part 60 with a structure for fixing it to the objects to be shielded 11, 12. As a result, the structure of the shield member 21 can be simplified.

[0124] In particular, in this embodiment, the movable part 60 does not have any part that physically engages with the objects to be shielded 11, 12. Therefore, it is not necessary to provide the movable part 60 with a structure for physically engaging with the objects to be shielded 11, 12. As a result, the structure of the shielding member can be simplified.

[0125] Furthermore, in this embodiment, the shielding member 21 does not have any portion that is fixed to the objects to be shielded 11, 12. Therefore, it is not necessary to provide the shielding member 21 with a structure for fixing it to the objects to be shielded 11, 12. As a result, the structure of the shielding member 21 can be simplified.

[0126] Furthermore, if it becomes unnecessary to provide movable part 60 or shielding member 21 with a structure for fixing to objects to be shielded 11, 12, it becomes easy to use one type of shielding member 21 to accommodate a plurality of types of objects to be shielded 11, 12. In other words, even if the size or shape of objects to be shielded 11, 12 is changed, it becomes easy to shield them with shielding member 21 of the same structure.

[0127] However, instead of this embodiment, the fixing part 50 may have a portion fixed to the objects to be shielded 11, 12. In this case, the objects to be shielded 11, 12 and the shielding member 21 can be handled as a single unit.

[0128] Although the preferred embodiments of the connector of the present disclosure have been described above, the present disclosure is not limited thereto.
