[Technical field]

[0001] The present disclosure relates to a shielding member, a connector with a shielding member, a shielded electronic component, a shield, and a shielding structure. [Background technology]

[0002] Patent Documents 1 and 2 disclose connectors with shielding members. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-096933 [Patent Document 2] JP 2018-186056 A Summary of the Invention [Problem to be solved by the invention]

[0004] The problem to be solved by the first aspect of the present disclosure is to prevent a gap from occurring or becoming larger in the first direction between the contact object and the shielding member due to variation in the distance in the first direction between the attachment object and the contact object. The problem to be solved by the second aspect of the present disclosure is to simplify the structure of the shield member. The problem to be solved by the third aspect of the present disclosure is to realize an inexpensive connector with a shielding member. [Means for solving the problem]

[0005] (First aspect) The shielding member of aspect 1-1 is a shielding member for shielding an object to be shielded, and comprises a base that does not displace relative to an object to be attached, and a movable shielding part that is displaceable relative to the base, wherein the movable shielding part has a contact part configured to contact a contact object by bringing the contact object and the shielding member closer in a first direction, the contact part of the movable shielding part is configured so that contact pressure is generated in the first direction upon contact with the contact object, and the movable shielding part is configured to displace in the first direction when the contact part is pressed in the first direction by the contact object.

[0006] The present aspect relates to a shielding member for shielding an object to be shielded. In this aspect, the shield member includes a base portion that does not displace relative to the attachment object, and a movable shield portion that is displaceable relative to the base portion. Therefore, the object to be shielded can be shielded by the movable shield portion which is displaceable relative to the object to which the shield is attached.

[0007] In this aspect, the movable shield part has a contact part configured to come into contact with a contact object by bringing the contact object and the shield member closer in a first direction. The contact part of the movable shield part is configured to generate a contact pressure in the first direction by contact with the contact object. The movable shield part is configured to be displaced in the first direction when the contact part is pressed in the first direction by the contact object. This prevents a gap from occurring in the first direction between the contact object and the shielding member or the gap from becoming larger due to variation in the distance in the first direction between the attachment object and the contact object.

[0008] The attachment object means an object to which the shielding member is attached. In the embodiment described later, the attachment object is a board, but the attachment object in this embodiment is not limited to this. Also, in the embodiment described later, the shielding member is directly attached to the attachment object (board) at the connection portion. However, the case where the shielding member is indirectly attached to the attachment object via a member other than the shielding member (e.g., a connector housing) is also included in the case where "the shielding member is attached to the attachment object." The contact object means an object that the shielding member comes into contact with. In the embodiment described later, the contact object is a mating board (second board) or a mating shielding member (second shielding member), but the contact object in this embodiment is not limited to these. The contact object in this embodiment may be, for example, another component attached to the mating board, such as a housing provided in the mating connector or a ground terminal provided in the mating connector. In the embodiment described below, the contact portion of the movable shield portion comes into contact with the contact object, thereby electrically connecting the shield member and the contact object, but the present embodiment is not limited to this. In the embodiment described below, the shielding member is attached to the object to which the shielding member is attached, thereby electrically connecting the shielding member to the object to which the shielding member is attached, but the present embodiment is not limited to this. In the embodiment described below, the first direction is a direction perpendicular to the surface of the object to which the device is attached, but the first direction in this embodiment is not limited to this. In the embodiment described below, the shielding member is made by subjecting a plate material to processes such as punching and bending, but the shielding member of this embodiment is not limited to this. In the embodiment described below, the movable shield part does not have a portion that is fixed to an object to be shielded, but the movable shield part of this embodiment is not limited to this. In the embodiment described below, the movable shield part is configured to be displaceable relative to the base part only in the first direction, but the movable shield part of this embodiment is not limited to this. The movable shield part of this embodiment may be displaceable in directions other than the first direction.

[0009] The shielding member according to aspect 1-2 is the same as aspect 1-1, in which the contact portion is formed in a convex shape so as to come into point contact with the contact object.

[0010] In this aspect, the contact portion is formed in a convex shape so as to come into point contact with the contact object. For this reason, it is well suited to the planar contact portion of the contact object.

[0011] The shielding member according to aspect 1-3 is the shielding member of any one of aspects 1-1 to 1-2, in which the movable shield portion does not have a portion that is fixed to the object to be shielded.

[0012] In this aspect, the movable shield portion does not have a portion that is fixed to the object to be shielded. This eliminates the need to provide the movable shield portion with a structure for fixing it to the object to be shielded, thereby simplifying the structure of the shield member.

[0013] In the embodiment described later, the movable shield part does not have a part that physically engages with the object to be shielded, but the movable shield part of this aspect is not limited to this. The movable shield 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 shield part has a part that physically engages with the object to be shielded is a case in which the movable shield part is in slidable contact with the object to be shielded.

[0014] A shielding member according to a 1-4th aspect is any one of the aspects 1-1 to 1-3, in which the movable shield portion does not have a portion that physically engages with the object to be shielded.

[0015] In this aspect, the movable shield portion does not have any part that physically engages with the object to be shielded. This eliminates the need to provide the movable shield portion with a structure for physically engaging with the object to be shielded, thereby simplifying the structure of the shield member.

[0016] A shielding member according to a 1-5th aspect is any one of the aspects 1-1 to 1-4, wherein the shielding member does not have a portion fixed to the object to be shielded.

[0017] In this aspect, the shield member does not have a portion that is fixed to the object to be shielded. This eliminates the need to provide the shielding member with a structure for fastening it to the object to be shielded, thereby simplifying the structure of the shielding member.

[0018] Moreover, if it becomes unnecessary to provide the shielding member with a structure for fixing it to the object to be shielded, it becomes easy 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 is changed, it becomes easy to shield it with a shielding member of the same structure.

[0019] The shielding member according to aspect 1-6 is any one of aspects 1-1 to 1-5, in which the movable shield portion does not have a portion fixed to the object to be shielded, and the base portion has a portion fixed to the object to be shielded.

[0020] In this aspect, the movable shield portion does not have a portion that is fixed to the object to be shielded. This eliminates the need to provide the movable shield with a structure for fixing it to the object to be shielded. In this aspect, the base has a portion that is fixed to the object to be shielded. This makes it possible to handle the object to be shielded and the shielding member as a single unit.

[0021] The shielding member according to aspect 1-7 is any one of aspects 1-1 to 1-6, wherein the base portion includes a fixed shield portion that shields the object to be shielded.

[0022] In this aspect, the base portion includes a fixed shield portion that shields an object to be shielded. Therefore, the object to be shielded can be shielded by both the fixed shield part that does not move relative to the object to which the shield is attached, and the movable shield part that is moveable relative to the object to which the shield is attached.

[0023] In the embodiment described later, the fixed shield part is cylindrical, but the fixed shield part of this aspect is not limited to this. The fixed shield part of this aspect may have any shape for shielding the object to be shielded. The part having any shape for shielding the object to be shielded is, for example, a plate-like part that covers the object to be shielded from a specific direction.

[0024] The shield member according to aspect 1-8 is the shield member according to aspect 1-7, wherein the fixed shield portion is cylindrical, and the movable shield portion is cylindrical.

[0025] In this aspect, the fixed shield part is cylindrical, and the movable shield part is cylindrical. This allows for high shielding performance.

[0026] As will be understood from the embodiments described below, the term "cylindrical" in this disclosure includes not only a completely cylindrical shape with no gaps in the circumferential direction, but also a shape with some gaps at specific positions in the circumferential direction.

[0027] A shield member according to a 1-9th aspect is any one of the aspects 1-1 to 1-8, wherein the movable shield portion is made up of a plurality of portions that are displaceable independently of one another.

[0028] In this aspect, the movable shield portion is composed of a plurality of portions which are displaceable independently of one another. Therefore, even if the contact object is tilted relative to a predetermined state, a good contact state can be achieved between the movable shield portion and the contact object.

[0029] A connector with a shielding member according to aspects 1-10 is a connector with a shielding member that can be attached to an attachment object which is a board and can be connected to a mating connector in a first direction, the connector with a shielding member comprising: a shielding object which is a connector; and a shielding member; the connector comprises a terminal, the terminal having a contact portion that contacts the terminal of the mating connector; the shielding member comprises a base that does not displace relative to the attachment object and a movable shield portion that is displaceable relative to the base; the movable shield portion has a contact portion configured to contact the contact object by bringing the contact object and the shielding member closer to each other in a first direction; the contact portion of the movable shield portion is configured so that a contact pressure is generated in the first direction by contact with the contact object; the contact object is a mating board as a mating attachment object to which the mating connector is attached, a mating shield member attached to the mating board, or another member attached to the mating board; and the movable shield portion is configured to displace in the first direction when the contact portion is pressed in the first direction by the contact object.

[0030] This aspect relates to a connector with a shield member that can be attached to an attachment object, which is a board, and that can be connected to a mating connector in a first direction. In this aspect, the shield member includes a base portion that does not displace relative to the attachment object, and a movable shield portion that is displaceable relative to the base portion. Therefore, the object to be shielded can be shielded by the movable shield portion which is displaceable relative to the object to which the shield is attached. In this aspect, the movable shield part has a contact part configured to come into contact with a contact object by bringing the contact object and the shield member closer to each other in a first direction. The contact part of the movable shield part is configured to generate a contact pressure in the first direction by contact with the contact object. The movable shield part is configured to be displaced in the first direction when the contact part is pressed by the contact object in the first direction. This prevents a gap from occurring in the first direction between the contact object and the shielding member or the gap from becoming larger due to variation in the distance in the first direction between the attachment object and the contact object.

[0031] In this embodiment, "other components attached to the mating board" refers to, for example, a housing provided in the mating connector and a ground terminal provided in the mating connector, but also includes other components that are neither a mating shield member nor a mating connector.

[0032] The connector with a shield member according to aspect 1-11 is the connector according to aspect 1-10, wherein the contact portion of the movable shield portion is formed in a convex shape so as to come into point contact with the contact object.

[0033] In this aspect, the contact portion of the movable shield portion is formed in a convex shape so as to come into point contact with the contact object. For this reason, it is well suited to the planar contact portion of the contact object.

[0034] A connector with a shielding member in accordance with aspect 1-12 is, in aspect 1-10 or 1-11, configured so that the contact portion of the terminal of the connector is configured so that contact pressure is generated in a direction within a plane perpendicular to the first direction upon contact with the terminal of the mating connector.

[0035] Now, let us consider a case where the contact portion of the terminal of the connector is configured so that contact pressure is generated in a first direction by contact with the terminal of the mating connector. In this case, in order to ensure a stable electrical connection, it is necessary to continue to strongly press the connector and the mating connector in the first direction, and this, combined with the pressing force in the first direction between the movable shield part and the contact object, makes both boards (the board and the mating board) prone to bending. Therefore, in this aspect, the contact portion of the terminal of the connector is configured so that contact pressure is generated in a direction within a plane perpendicular to the first direction upon contact with the terminal of the mating connector. This makes it possible to prevent both substrates (the substrate and the mating substrate) from bending.

[0036] In the embodiment described below, a large number of terminals are provided. In this case, the above-mentioned effects are particularly important. However, the terminals of this embodiment are not limited to this.

[0037] A shielded electronic component according to a first to thirteenth aspect of the present invention is a shielded electronic component comprising a shielded object which is an electronic component, and a shield for shielding the shielded object, the electronic component comprising a first connector attached to a first attachment object and a second connector attached to a second attachment object, the shield comprising a first shielding member attached to the first attachment object, the first shielding member comprising a base which does not displace relative to the first attachment object, and a movable shielding part which is displaceable relative to the base, the movable shielding part having a contacting part configured to come into contact with a contacting object which is the second attachment object by bringing the first shielding member closer to the contacting object in a first direction, the contacting part of the movable shielding part being configured such that contact pressure is generated in the first direction by contact with the contacting object, and the movable shielding part being configured to be displaced in the first direction when the contacting part is pressed in the first direction by the contacting object.

[0038] A shielded electronic component according to a first to fourteenth aspect of the present invention is a shielded electronic component comprising a shielded object which is an electronic component, and a shield for shielding the shielded object, the electronic component comprising a first connector attached to a first attachment object and a second connector attached to a second attachment object, the shield comprising a first shielding member attached to the first attachment object and a second shielding member attached to the second attachment object, the first shielding member comprising a base which does not displace relative to the first attachment object and a movable shielding part which is displaceable relative to the base, the movable shielding part having a contacting part configured to come into contact with a contacting object which is the second shielding member by bringing the first shielding member closer to the contacting object in a first direction, the contacting part of the movable shielding part being configured such that a contact pressure is generated in the first direction by contact with the contacting object, and the movable shielding part being configured to be displaced in the first direction when the contacting part is pressed in the first direction by the contacting object.

[0039] (Second aspect) The shielding member of aspect 2-1 is a shielding member for shielding an object to be shielded, and comprises a base that does not displace relative to the object to be attached, and a movable shield part that is displaceable relative to the base, and the movable shield part does not have a part that is fixed to the object to be shielded.

[0040] The present aspect relates to a shielding member for shielding an object to be shielded. In this aspect, the shield member includes a base portion that does not displace relative to the attachment object, and a movable shield portion that is displaceable relative to the base portion. Therefore, the object to be shielded can be shielded by the movable shield portion which is displaceable relative to the object to which the shield is attached.

[0041] Furthermore, in this aspect, the movable shield portion does not have a portion that is fixed to the object to be shielded. This eliminates the need to provide the movable shield portion with a structure for fixing it to the object to be shielded, thereby simplifying the structure of the shield member.

[0042] The attachment object means an object to which the shield member is to be attached. In the embodiment described below, the attachment object is a substrate, but the attachment object in this embodiment is not limited to this. In the embodiment described below, the shielding member is attached to the object to which the shielding member is attached, thereby electrically connecting the shielding member to the object to which the shielding member is attached, but the present embodiment is not limited to this. In the embodiment described below, the first direction is a direction perpendicular to the surface of the object to which the device is attached, but the first direction in this embodiment is not limited to this. In the embodiment described below, the shielding member is made by subjecting a plate material to processes such as punching and bending, but the shielding member of this embodiment is not limited to this. In the embodiment described later, the movable shield part has a contact part configured to contact the contact object, the contact part is configured to generate a contact pressure in a first direction by contacting the contact object, and the movable shield part is configured to be displaced in the first direction when the contact part is pressed in the first direction by the contact object. However, this aspect is not limited to this. For example, the movable shield part of this aspect does not have to be displaceable in the first direction. In this case, the movable shield part may be displaceable in any direction in a plane perpendicular to the first direction, or may be displaceable only in one predetermined direction in a plane perpendicular to the first direction.

[0043] The shielding member according to aspect 2-2 is the same as aspect 2-1, in which the movable shield portion does not have a portion that physically engages with the object to be shielded.

[0044] In this aspect, the movable shield portion does not have any part that physically engages with the object to be shielded. This eliminates the need to provide the movable shield portion with a structure for physically engaging with the object to be shielded, thereby simplifying the structure of the shield member.

[0045] The shielding member according to a 2-3 aspect is the shielding member according to the 2-1 or 2-2 aspect, in which the base portion does not have a portion that is fixed to the object to be shielded.

[0046] In this embodiment, the base does not have a portion that is fixed to the object to be shielded. This eliminates the need to provide the base with a structure for fixing the shield to the object to be shielded.

[0047] A shielding member according to a 2-4th aspect is any one of the aspects 2-1 to 2-3, wherein the shielding member does not have a portion fixed to the object to be shielded.

[0048] In this aspect, the shield member does not have a portion that is fixed to the object to be shielded. This eliminates the need to provide the shield with a structure for fixing it to the object to be shielded.

[0049] The shielding member according to aspect 2-5 is the shielding member according to aspect 2-1 or 2-2, wherein the base portion has a portion fixed to the object to be shielded.

[0050] In this aspect, the base has a portion that is fixed to the object to be shielded. This makes it possible to treat the shield and the object to be shielded as one unit.

[0051] The shielding member according to aspect 2-6 is any one of aspects 2-1 to 2-5, wherein the base portion includes a fixed shield portion that shields the object to be shielded.

[0052] In this aspect, the base portion includes a fixed shield portion that shields an object to be shielded. Therefore, the object to be shielded can be shielded by both the fixed shield part that does not move relative to the object to which the shield is attached, and the movable shield part that is moveable relative to the object to which the shield is attached.

[0053] The shield member according to aspect 2-7 is the shield member according to aspect 2-6, wherein the fixed shield part is cylindrical, and the movable shield part is cylindrical.

[0054] In this aspect, the fixed shield part is cylindrical, and the movable shield part is cylindrical. This allows for high shielding performance.

[0055] The shield member according to aspect 2-8 is the shield member according to aspect 2-7, wherein a portion of one of the fixed shield part and the movable shield part is disposed inside the other.

[0056] In this aspect, a portion of one of the fixed shield part and the movable shield part is disposed inside the other. This makes it possible to prevent a gap (a gap in the axial direction of the tube) from occurring between the cylindrical fixed shield part and the cylindrical movable shield part.

[0057] The connector with a shielding member in accordance with aspect 2-9 is a connector with a shielding member that can be attached to an attachment object which is a substrate and can be connected to a mating connector in a first direction, the connector with a shielding member comprising: a shielding object which is a connector; and a shielding member, the connector comprising a movable housing which is displaceable relative to the attachment object, the shielding member comprising a base which is not displaceable relative to the attachment object and a movable shield part which is displaceable relative to the base, and the movable shield part does not have a portion which is fixed to the shielding object.

[0058] This aspect relates to a connector with a shield member that can be attached to an attachment object, which is a board, and that can be connected to a mating connector in a first direction. In this aspect, the connector with a shield member includes an object to be shielded, which is a connector, and a shield member. The shield member includes a base portion that does not move relative to the object to which the shield member is attached, and a movable shield portion that is movable relative to the base portion. Therefore, the object to be shielded can be shielded by the movable shield portion which is displaceable relative to the object to which the shield is attached.

[0059] Also, in this aspect, the connector includes a movable housing that is displaceable relative to the object to which it is attached, but the movable shield portion does not have a portion that is fixed to the object to be shielded. Therefore, compared to, for example, an embodiment in which the movable shield part is fixed to a movable housing of a connector, it is not necessary to provide the movable shield part with a structure for fixing it to the movable housing, and as a result, the structure of the shield member can be simplified.

[0060] In the embodiment described later, the movable housing is displaceable in any of the X, Y, and Z directions, and in a direction oblique to these directions, but the movable housing of this embodiment is not limited to this. For example, the movable housing of this embodiment does not have to be displaceable in the Z direction. In this case, the movable shield part may be displaceable in any direction in a plane perpendicular to the Z direction, or may be displaceable only in one predetermined direction in a plane perpendicular to the Z direction. Here, the Z direction is, for example, the connection direction with the mating connector.

[0061] The connector with a shielding member according to aspect 2-10 is the connector of aspect 2-9, in which the movable shield portion does not have a portion that physically engages with the object to be shielded.

[0062] In this aspect, the movable shield portion does not have any part that physically engages with the object to be shielded. This eliminates the need to provide the movable shield portion with a structure for physically engaging with the object to be shielded, thereby simplifying the structure of the shield member.

[0063] The connector with a shielding member according to a second aspect of the present invention is the connector with a shielding member according to the second aspect of the present invention, wherein the base portion has a portion that is fixed to the object to be shielded.

[0064] In this aspect, the base has a portion that is fixed to the object to be shielded. This makes it possible to handle the object to be shielded and the shielding member as a single unit.

[0065] (Third aspect) The connector group with a shield member according to aspect 3-1 includes a connector group made up of a plurality of types of connectors, and a shield member capable of accommodating any connector selected from the connector group.

[0066] Conventionally, in connectors with shielding members that include a shielding member and a connector, the shielding members are not interchangeable (see, for example, Patent Document 2). Therefore, it is necessary to design a shielding member for each type of connector. In this aspect, the connector group with shield member includes a connector group and a shield member. The connector group is made up of a plurality of types of connectors. The shield member can accommodate any connector selected from the connector group. This eliminates the need to design a shielding member for each type of connector, making it possible to realize an inexpensive connector with a shielding member.

[0067] The connector group with shielding member according to aspect 3-2 comprises, in aspect 3-1, another connector group consisting of multiple types of connectors, and another shielding member capable of accommodating any connector selected from the other connector group.

[0068] A group of connectors with a shield member according to an aspect 3-3 is any one of aspects 3-1 to 3-2, in which the shield member does not have a portion fixed to the connector.

[0069] Incidentally, when the shielding member has a portion that is fixed to a connector, it is necessary to provide a common fixing portion (a portion to which the shielding member is fixed) in all connectors belonging to the connector group. Therefore, in this aspect, the shield member does not have a portion that is fixed to the connector. Therefore, the above-mentioned necessity is eliminated, and a cheaper connector with a shielding member can be realized.

[0070] A shielding member according to a third aspect is any one of the first to third aspects, wherein the shielding member has a portion fixed to a connector.

[0071] According to this aspect, the connector and the shield can be handled as one unit, which simplifies the step of placing the connector with the shield member on the object in the method for producing the mounting structure for the connector with the shield member (mounting method).

[0072] A group of connectors with shielding members according to aspect 3-5 is any one of aspects 3-1 to 3-4, in which the shielding members include a base portion that does not displace relative to an object to which the shielding members are attached, and a movable shield portion that is displaceable relative to the base portion.

[0073] A connector group with a shield member according to a third aspect is any one of the connector groups according to any one of the first to fifth aspects, wherein the connector group includes a connector having a movable housing.

[0074] A connector group with a shield member according to aspect 3-7 is any one of aspects 3-1 to 3-5, in which the shield member does not have a portion fixed to the connector, and the connector group includes a connector provided with a movable housing.

[0075] A connector group with a shielding member according to aspect 3-8 is, in any of aspects 3-1 to 3-5, wherein the shielding member comprises a base that does not displace relative to an object to which the shielding member is attached and a movable shield part that is displaceable relative to the base, the base has a portion that is fixed to the connector, the movable shield part does not have a portion that is fixed to the connector, and the connector group includes a connector with a movable housing.

[0076] A connector group with a shielding member according to aspect 3-9 is any of aspects 3-1 to 3-5, in which the shielding member has a base that does not displace relative to the object to which it is attached and a movable shielding portion that is displaceable relative to the base, the shielding member does not have a portion that is fixed to the connector, and the connector group includes a connector having a movable housing.

[0077] The term "connector having a movable housing" includes not only connectors in which the movable housing is in a floating state due to the terminals, but also connectors in which the movable housing is not in a floating state. The movable housing refers to a housing that is configured to be displaceable relative to an object to which the connector is attached.

[0078] A method for selling a connector with a shielding member according to an embodiment of the present invention is carried out by presenting a group of connectors with a shielding member according to any one of embodiments of the present invention, from 3-1 to 3-9.

[0079] This aspect relates to a method for selling a connector with a shield member. In this embodiment, the method for selling the connector with the shielding member is carried out by presenting the group of connectors with the shielding member according to the embodiment 3-1 or 3-2. This allows connectors with shielding members to be sold at low prices.

[0080] A method for producing an installation structure for a connector with a shielding member (installation method for a connector with a shielding member) relating to aspects 3-11 includes the steps of selecting and preparing one connector from a group of connectors consisting of multiple types of connectors, preparing a shielding member capable of accommodating any connector selected from the group of connectors, and placing the one connector and the shielding member on an object to be installed so that the shielding member accommodates the one connector.

[0081] According to this aspect, the prepared shielding member can accommodate any connector selected from the group of connectors, so the step of preparing the shielding member is simplified.

[0082] A method for producing an installation structure for a connector with a shielding member (installation method for a connector with a shielding member) relating to aspects 3-12 includes the steps of selecting one connector, preparing a shielding member capable of accommodating any connector belonging to the connector group to which the selected one connector belongs, and placing the one connector and the shielding member on an object to be installed so that the one connector is accommodated in the shielding member.

[0083] It should be noted that the "attachment structure for a connector with a shielding member" refers to a structure in which a connector with a shielding member is attached to an object to which it is attached.

[0084] The shielding member according to the third to thirteenth aspects is a shielding member capable of accommodating any connector selected from a connector group constituted by a plurality of types of connectors.

[0085] The connector with shielding member according to any one of the third to fourteenth aspects includes one connector selected from a connector group consisting of a plurality of types of connectors, and a shielding member capable of accommodating any connector selected from the connector group.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0087] Hereinafter, preferred embodiments of a shielding member and a shielding structure including the same according to the present disclosure will be described.

[0088] In addition, the +X direction of the arrow 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 as the upper side in the up-down direction. However, this does not limit the position of the shielding member etc. when in use.

[0089] First Embodiment 1 to 7 show a shield structure 100 according to a first embodiment, etc.

[0090] The shield structure 100 includes attachment objects 91 and 92, electronic components 11 and 12, and a shield 21. In the shield structure 100, electronic components 11 and 12, which are “objects to be shielded”, are shielded by a shield 21. The electronic components 11 and 12 and the shield 21 are attached to objects 91 and 92 to be attached.

[0091] The attachment objects 91 and 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 to each other with their thickness directions oriented in the same direction (Z direction). Hereinafter, the first substrate 91 may be simply referred to as substrate 91, and the second substrate 92 may be simply referred to as counterpart substrate 92.

[0092] The electronic components 11 and 12 are a connector pair 11 and 12 composed 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. 3). Hereinafter, the first connector 11 may be simply referred to as the connector 11, and the second connector 12 may be simply referred to as the mating connector 12.

[0093] As shown in FIG. 2, the first connector 11 is a floating connector. The first connector 11 includes at least one first terminal 30, and housings 41, 42 that hold the at least one first terminal 30. The housings 41, 42 include a fixed housing 41 that is fixed to a first attachment object 91, and a movable housing 42 that is displaceable relative to the fixed housing 41. The movable housing 42 is displaceable in any of the X, Y, and Z directions, as well as directions oblique to these directions. The first terminal 30 has a connection portion 31 connected to the first attachment object 91 by soldering, and a contact portion 32 that comes into contact with a terminal 50 of the second connector 12. The first terminal 30 is held by the fixed housing 41 and also by the movable housing 42. An elastically deformable portion is formed between a portion of the first terminal 30 held by the fixed housing 41 and a portion of the first terminal 30 held by the movable housing 42. This allows the movable housing 42 to be displaced.

[0094] The second connector 12 is a connector that is not a floating connector. The second connector 12 includes at least one second terminal 50 and a housing 141 that holds the at least one second terminal 50. The housing 141 includes a fixed housing 141 that is fixed to the second attachment object 92, and does not include a movable housing that is displaceable with respect to the second attachment object 92. The second terminal 50 has a connection portion 51 that is connected to the second attachment object 92 by soldering, and a contact portion 52 that comes into contact with the first terminal 30 . In the illustrated example, the fixed housing 141 is made up of two molded parts 141a and 141b that are molded separately from each other (see FIG. 2).

[0095] FIG. 5 is an exploded perspective view of the first connector 11 and the second connector 12. As shown in FIG.

[0096] At least one first terminal 30 includes a plurality of first signal terminals 30A. The plurality of first signal terminals 30A are configured by a large number of pairs of first signal terminals 30A arranged in the front-rear direction. At least one second terminal 50 includes a plurality of second signal terminals 50A. The plurality of second signal terminals 50A are configured by a large number of pairs of second signal terminals 50A arranged in the front-rear direction. The contact portions 32 of the pair of first signal terminals 30A are in contact with the contact portions 52 of the pair of second signal terminals 50A so as to sandwich them from the outer sides in the width direction (see FIGS. 2 and 3).

[0097] The contact pressure generated by contact between the contact portion 32 of the first signal terminal 30A and the contact portion 52 of the second signal terminal 50A occurs in a direction within a plane (within the XY plane) perpendicular to the direction in which the first mounting object 91 and the second mounting object 92 face each other (Z direction).

[0098] At least one first terminal 30 includes a plurality of first power supply terminals 30B. At least one second terminal 50 includes a plurality of second power supply terminals 50B. The first power supply terminals 30B are arranged in an area on one side in the front-rear direction and an area on the other side in the front-rear direction with respect to the area where the first signal terminals 30A are arranged. The same is true for the second power supply terminals 50B.

[0099] As can be seen from Figure 5 etc., the contact pressure generated by contact between the first power supply terminal 30B and the second power supply terminal 50B occurs in a direction within a plane (within the XY plane) perpendicular to the direction in which the first mounting object 91 and the second mounting object 92 face each other (Z direction).

[0100] (Shield 21) The shield 21 is composed of only a first shield member 21 .

[0101] Specifically, the first shield member 21 is produced by subjecting a conductive plate material to processes such as punching and bending.

[0102] The first shield member 21 has a substantially symmetrical structure in both the front-rear direction and the width direction.

[0103] The first shielding member 21 has a cylindrical shape (specifically, a rectangular cylindrical shape) and accommodates the first connector 11 and the second connector 12 therein (see FIG. 3).

[0104] As shown in FIGS. 6 and 7, the first shield member 21 has a base portion 60, a movable shield portion 70, and at least one elastic support portion 80. The base 60 is configured so as not to be displaced relative to the first substrate 91 . The movable shield portion 70 is configured to be displaceable relative to the base portion 60 . At least one elastic support portion 80 elastically supports the movable shield portion 70 .

[0105] (base 60) The base 60 includes a fixed shield portion 61 . The fixed shield part 61 is cylindrical (specifically, rectangular cylindrical). The fixed shield part 61 includes a pair of first plate parts 61a and a pair of second plate parts 61b. The pair of first plate portions 61a face each other in the width direction. Specifically, each of the first plate portions 61a has a flat plate shape with its thickness direction aligned in the width direction. The pair of second plate portions 61b face each other in the front-rear direction. Specifically, each second plate portion 61b has a flat plate shape with a plate thickness direction aligned in the front-rear direction.

[0106] The base 60 includes a number of connecting portions 62a, 62b, and 62c. Each of the multiple connection portions 62a, 62b, 62c is joined by soldering to a pad (not shown) formed on the upper surface of the first substrate 91. As a result, the first shielding member 21 is attached to the first substrate 91, and the first shielding member 21 and the first substrate 91 are electrically connected to each other.

[0107] The multiple connection portions 62a, 62b, 62c include multiple first connection portions 62a protruding from the first plate portion 61a. Each of the first connection portions 62a has a shape that protrudes downward from the lower edge of the first plate portion 61a. A plurality of (four) first connection portions 62a are formed for each of the first plate portions 61a.

[0108] The multiple connection portions 62a, 62b, 62c include multiple second connection portions 62b protruding from the second plate portion 61b. Each second connection portion 62b has a shape that protrudes downward from the lower edge of the second plate portion 61b. A plurality (two) of second connection portions 62b are formed for each second plate portion 61b.

[0109] The plate width dimension (dimension in the width direction) of the second connecting portion 62b is larger than the plate width dimension (dimension in the front-rear direction) of the first connecting portion 62a, and specifically is three or more times the plate width dimension of the first connecting portion 62a. Since the lower edge of the second plate portion 61b is located above the lower edge of the first plate portion 61a in the vertical direction, the vertical dimension of the second connecting portion 62b is greater than the vertical dimension of the first connecting portion 62a.

[0110] The multiple connection portions 62a, 62b, 62c include multiple (four) third connection portions 62c whose plate thickness directions are oriented in the up-down direction. The third connection portion 62c is connected to the first plate portion 61a of the fixed shield part 61 via a bent portion. Since the third connection portion 62c has its plate thickness oriented in the vertical direction, it can have a larger joint area than the first connection portion 62a or the second connection portion 62b, making it easier to ensure the mounting strength of the first shield member 21. Further, the positions of the third connection portions 62c in the front-rear direction correspond to the front and rear ends of the first plate portion 61a. This also makes it easier to ensure the mounting strength of the first shield member 21.

[0111] The fixed shield part 61 has a plurality of cutout parts 63 . The cutout portions 63 are formed in the first plate portions 61a of the fixed shield part 61. Specifically, each of the pair of first plate portions 61a has two cutout portions 63. The cutout portion 63 is a portion obtained by cutting out a part near the lower edge of the fixed shield portion 61. The position of the cutout portion 63 corresponds to the position where the first power supply terminal 30B of the first connector 11 is disposed. This ensures an appropriate distance between the fixed shield portion 61 and the first power supply terminal 30B. The cutout portion 63 is located adjacent to the third connecting portion 62c on the inner side in the front-rear direction.

[0112] (movable shield part 70) The movable shield portion 70 is cylindrical (specifically, rectangular cylindrical). The movable shield portion 70 includes a pair of first plate portions 71a and a pair of second plate portions 71b. The pair of first plate portions 71a face each other in the width direction. Specifically, each of the first plate portions 71a has a flat plate shape with its thickness direction aligned in the width direction. The pair of second plate portions 71b face each other in the front-rear direction. Specifically, each of the second plate portions 71b has a flat plate shape with a plate thickness direction aligned in the front-rear direction.

[0113] The first plate portion 71a of the movable shield part 70 is located outboard of the first plate portion 61a of the fixed shield part 61 in the width direction. The second plate portion 71b of the movable shield part 70 is located outside the second plate portion 61b of the fixed shield part 61 in the front-rear direction.

[0114] When the movable shield part 70 is in the initial position (see FIGS. 6 and 7), the lower end of the movable shield part 70 is located lower than the upper end of the fixed shield part 61. This prevents the lower end of the movable shield part 70 from colliding with the upper end of the fixed shield part 61 and buckling. Also, a vertical gap is prevented from occurring between the lower end of the movable shield part 70 and the upper end of the fixed shield part 61.

[0115] The movable shield portion 70 includes a supported portion 72 supported by an elastic supporting portion 80 . The supported portion 72 includes a pair of first portions 72a and a pair of second portions 72b. A curved portion is formed between the first portions 72a and the second portions 72b. This allows the supported portion 72 to be formed in a frame shape.

[0116] An upper end of the first portion 72a is connected to an upper end of the first plate portion 71a via a bent portion. The first plate portion 71a is formed by bending a portion above the first portion 72a outward in the width direction. An upper end of the second portion 72b is connected to an upper end of the second plate portion 71b via a bent portion. The second plate portion 71b is formed by bending a portion above the second portion 72b outward in the front-rear direction.

[0117] (Contact portion 73) The movable shield portion 70 has a plurality of contact portions 73a, 73b. Each of the multiple contact portions 73a, 73b comes into contact with the second substrate 92, which is an "object to be connected." Specifically, each of the multiple contact portions 73a, 73b comes into contact with a pad (not shown) formed on the lower surface of the second substrate 92. This electrically connects the first shield member 21 and the second substrate 92.

[0118] The multiple contact portions 73a, 73b include multiple first contact portions 73a protruding from the first portion 72a of the supported portion 72. Therefore, the first contact portions 73a are located on the same plane as the first plate portion 61a of the fixed shield part 61, the elastic support portion 80, and the first portion 72a. A plurality of (three) first contact portions 73a are formed for each first portion 72a. The first contact portions 73a are substantially semicircular in shape.

[0119] The multiple contact portions 73a, 73b include multiple second contact portions 73b protruding from the second portion 72b of the supported portion 72. Therefore, the second contact portions 73b are located on the same plane as the first plate portion 61a and the second portion 72b of the fixed shield part 61. A plurality of (two) second contact portions 73b are formed for each second portion 72b. The second contact portions 73b are substantially semicircular in shape.

[0120] Hereinafter, when there is no need to distinguish between the first contact portion 73a and the second contact portion 73b, they will simply be referred to as the contact portion 73. Although not shown, the pad formed on the lower surface of the second substrate 92 has an area larger than the contact area between the contact portion 73 of the first shield member 21 and the pad. Therefore, even if the movable shield part 70 of the first shield member 21 and the second substrate 92 are slightly misaligned in the XY plane, the two can be in contact with each other. In particular, in this embodiment, the first shield member 21 does not have a structure for displacing the movable shield part 70 in the XY plane. In such a case, the above configuration is particularly effective.

[0121] (Elastic support part 80) At least one elastic support portion 80 includes an elastic support portion 80 on one side in the width direction and an elastic support portion 80 on the other side in the width direction. The elastic support part 80 connects the first plate part 61a of the fixed shield part 61 and the first part 72a of the supported part 72 of the movable shield part . The elastic support portion 80 is located on the same plane as the first plate portion 61a and the first portion 72a.

[0122] The elastic support portion 80 includes a pair of spring pieces 81 . The pair of spring pieces 81 have a symmetrical shape in the front-rear direction. Each spring piece 81 has a lower portion 81a extending diagonally upward and outward in the front-to-rear direction, an upper portion 81b extending diagonally upward and inward in the front-to-rear direction, and a middle portion 81c connecting the lower portion 81a and the upper portion 81b. The lower portion 81a and the upper portion 81b extend linearly, and the middle portion 81c extends in a substantially arc shape.

[0123] At a base end portion 80a of the elastic support portion 80, one spring piece 81 and the other spring piece 81 are integrated together. At the tip end 80b of the elastic support portion 80, one spring piece 81 and the other spring piece 81 are integrated together. This prevents stress from concentrating on the base end portion 80a or the tip end portion 80b of the elastic support portion 80.

[0124] The first shield member 21 is made of a conductive material. Specifically, the first shield member 21 is made of a single conductive plate. The first shield member 21 is formed as a whole into a cylindrical shape (specifically, a rectangular cylindrical shape) by the fixed shield part 61 and the movable shield part . As shown in Figure 6, a joint 21h is formed at a position corresponding to one of the pair of second plate portions 61b of the fixed shield part 61 and one of the pair of second plate portions 71b of the movable shield part 70, where the ends of the plate materials constituting the first shield member 21 are joined together.

[0125] FIG. 3 shows a state in which the first connector 11 and the second connector 12 are connected. However, in the state shown in Figure 3, the contact portion 32 of the first terminal 30 of the first connector 11 and the contact portion 52 of the second terminal 50 of the second connector 12 are in contact, and the multiple contact portions 73a, 73b of the movable shield part 70 are in contact with the second substrate 92, but the movable shield part 70 has not been displaced from its initial position. Although the first connector 11 and the second connector 12 are normally connected in the state shown in Fig. 3, the first connector 11 and the second connector 12 can be connected even deeper. In other words, even if the distance between the first board 91 and the second board 92 is shorter than the distance shown in Fig. 3, 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 in the figure, when the distance between the first substrate 91 and the second substrate 92 becomes smaller than the distance shown in Figure 3, the movable shield portion 70 is pressed downward by the second substrate 92 at the multiple contact portions 73a, 73b, and is elastically displaced downward from the initial position.

[0126] <Action and effect> Next, the effects of this embodiment will be described.

[0127] In this embodiment, the shield member 21 includes a base portion 60 that is not displaced relative to the attachment object 91 , and a movable shield portion 70 that is displaceable relative to the base portion 60 . Therefore, the movable shield part 70 which is displaceable relative to the object 91 to which the shielding is to be performed can shield the object to be shielded (the connector pair 11, 12).

[0128] Moreover, in this embodiment, the movable shield part 70 has a contact part 73 configured to come into contact with the contact object 92 by bringing the contact object 92 and the shield member 21 closer to each other in the first direction. The contact part 73 of the movable shield part 70 is configured to generate a contact pressure in the first direction (Z direction) by contacting the contact object 92. The movable shield part 70 is configured to be displaced in the first direction (Z direction) when the contact part 73 is pressed in the first direction (Z direction) by the contact object 92. This prevents a gap from occurring in the first direction between the contact object 92 and the shield member 21 or from becoming larger due to variation in the distance in the first direction between the attachment objects 91, 92 and the contact object 92.

[0129] Here, it is assumed that the contact portion 73 of the movable shield part 70 is configured so that a contact pressure is generated in a direction within a plane perpendicular to the first direction upon contact with the contact object 92. In this case, if the position of the contact object 92 relative to the movable shield part 70 is deviated from a predetermined position in the direction within the plane, it is possible that an appropriate contact pressure cannot be obtained. Therefore, in this embodiment, the contact portion 73 of the movable shield portion 70 is configured so that contact pressure is generated in the first direction by contact with the contact object 92. For this reason, even if the position of the contact object 92 with respect to the movable shield part 70 is displaced from a predetermined position in a direction within a plane perpendicular to the first direction, an appropriate contact pressure can be easily obtained.

[0130] In this embodiment, the contact portion 73 of the movable shield portion 70 is formed in a convex shape so as to come into point contact with the contact object 92 . Therefore, it is compatible with the planar contact portion (pad, not shown) of the contact object 92.

[0131] Furthermore, in this embodiment, the movable shield part 70 does not have a portion that is fixed to the object to be shielded (the connector pair 11, 12). Therefore, it is not necessary to provide the movable shield portion 70 with a structure for fixing it to the object to be shielded (the connector pair 11, 12), and as a result, the structure of the shield member 21 can be simplified. Particularly, in this embodiment, the movable shield portion 70 does not have a portion that physically engages with the object to be shielded (the connector pair 11, 12). Therefore, it is not necessary to provide the movable shield portion 70 with a structure for physically engaging with the object to be shielded (the connector pair 11, 12), and as a result, the structure of the shield member 21 can be simplified. Moreover, in this embodiment, the shield member 21 does not have a portion that is fixed to the object to be shielded (the connector pair 11, 12). Therefore, it is not necessary to provide the shielding member 21 with a structure for fixing it to the object to be shielded (the connector pair 11, 12), and as a result, the structure of the shielding member 21 can be simplified. In addition, when the movable shield part 70 etc. does not have a portion to be fixed to the object to be shielded, it is of course not necessary to provide the object to be shielded with a structure for fixing the movable shield part 70 etc. As a result, the structure of the object to be shielded can be simplified.

[0132] In this embodiment, the base 60 also includes a fixed shield part 61 that shields the object to be shielded (the connector pair 11, 12). Therefore, the object to be shielded (connector pair 11, 12) can be shielded by both the fixed shield part 61 which does not move relative to the object to be attached 91 and the movable shield part 70 which is moveable relative to the object to be attached 91.

[0133] In this embodiment, the fixed shield part 61 is cylindrical, and the movable shield part 70 is cylindrical. This allows for high shielding performance. Furthermore, in this embodiment, a portion of the fixed shield part 61 is disposed inside the movable shield part 70. In other words, it can be said that a portion of either the fixed shield part 61 or the movable shield part 70 is disposed inside the other. This makes it possible to prevent a gap (a gap in the vertical direction) from occurring between the cylindrical fixed shield part and the cylindrical movable shield part.

[0134] In this embodiment, the elastic support part 80 is formed on the inner side of the shield 21 with respect to the movable shield part 70, as shown in FIG. Therefore, damage to the elastic support portion 80 due to contact from the outside can be suppressed.

[0135] Now, consider a case where contact portion 32 of terminal 30 of connector 11 is configured to generate contact pressure in a first direction (Z direction) by contacting terminal 50 of mating connector 12. In this case, in order to ensure a stable electrical connection, connector 11 and mating connector 12 must be continuously pressed strongly in the first direction, and coupled with the pressing force in the first direction (Z direction) between movable shield portion 70 and contact object 92, both boards (board 91 and mating board 92) are likely to bend. Therefore, in this embodiment, the contact portions 32 of the terminals 30 of the connector 11 are configured so that contact with the terminals 50 of the mating connector 12 generates a contact pressure in a direction within a plane perpendicular to the first direction. Therefore, it is possible to prevent both substrates (substrate 91 and counterpart substrate 92) from bending.

[0136] Second Embodiment 8 to 11 show a shield structure 200 according to a second embodiment, etc.

[0137] In the shield structure 200 according to the second embodiment, unlike the shield structure 100 according to the first embodiment, the shields 21, 22 include a second shield member 22 attached to a second substrate 92 in addition to a first shield member 21 attached to a first substrate 91. The first shield member 21 of the second embodiment shields the connector pair 11, 12 in cooperation with the second shield member 22. Therefore, in the second embodiment, the object (contact object) with which the first shield member 21 comes into contact is the second shield member 22.

[0138] In the second embodiment, the second connector 12 is a floating connector, and the first connector 11 is a connector that is not a floating connector. However, similar to the first embodiment, the first connector 11 may be a floating connector, and the second connector 12 may be a connector that is not a floating connector.

[0139] The first shielding member 21 of the second embodiment has a similar configuration to the first shielding member 21 of the first embodiment. Below, the configuration of the first shielding member 21 of the second embodiment will be mainly described with reference to differences from the first shielding member 21 of the first embodiment.

[0140] (Regulatory Organization 65, 75) As shown in FIG. 10, the first shield member 21 includes restriction mechanisms 65, 75 that restrict the movable shield part 70 from being excessively displaced in a direction (−Z direction) approaching a first attachment object 91 (attachment object). The restriction mechanisms 65, 75 are configured to restrict excessive displacement by abutting one part of the first shield member 21 with another part of the first shield member 21. In other words, the restriction mechanisms 65, 75 are completed within the first shield member 21.

[0141] The specific structures of the regulating mechanisms 65 and 75 are as follows. The regulating mechanisms 65, 75 are configured to include a contact portion 65 of the base 60 and a contact portion 75 of the movable shield part 70. When the movable shield part 70 moves in a direction approaching the first attachment object 91 (-Z direction), the contact portion 75 of the movable shield part 70 contacts the contact portion 65 of the base 60.

[0142] The contact portions 75 are formed at the lower ends of the pair of second portions 72 b of the supported portion 72 of the movable shield portion 70 . The abutted portions 65 are formed on the upper ends of the pair of second plate portions 61b of the fixed shield portion 61.

[0143] The abutted portion 65 is formed above a portion (upper edge of the first plate portion 61a) of the fixed shield portion 61 that is connected to the elastic support portion 80. As a result, the distance (vertical distance) between the abutting portion 75 and the abutted portion 65 is smaller than the vertical dimension of the elastic support portion 80.

[0144] The contact portion 75 is formed by bending a lower portion of the second portion 72b towards the inside of the shield 21 (inward in the front-rear direction). The abutted portion 65 is formed by bending an upper portion of the second plate portion 61b towards the inside of the shield 21 (inward in the front-rear direction). This allows the plate surfaces to come into contact with each other, rather than the plate end faces to come into contact with each other, making it possible to more reliably restrict excessive displacement of the movable shield part 70.

[0145] (Extension part 66) The fixed shield part 61 has an extension part 66 for closing the gap between the first plate part 71a and the second plate part 71b of the movable shield part . The extension portion 66 is a portion of the fixed shield portion 61 near the curved portion that connects the first plate portion 61a and the second plate portion 61b, and is a portion above the upper edge of the first plate portion 61a. It can be said that the extension portion 66 is a portion of the fixed shield portion 61 that is extended upward.

[0146] (First portion 70a and second portion 70b are displaceable independently of each other) The movable shield part 70 of the first shield member 21 is composed of a first part 70a and a second part 70b that are displaceable independently of each other. Therefore, even if the contact object 92 is tilted with respect to a predetermined state, a good contact state between the movable shield part 70 and the contact object 92 can be achieved. The first portion 70a constitutes one side of the movable shield part 70 in the front-rear direction. The second portion 70b constitutes the other side of the movable shield part 70 in the front-rear direction. The first portion 70a and the second portion 70b have substantially the same structure.

[0147] The first shielding member 21 is made by subjecting a single plate material to processes such as punching and bending. In the first shielding member 21, one part is connected to another part as a plate. In this respect, it is similar to the first shielding member 21 of the first embodiment. On the other hand, in the first shield member 21 of the second embodiment, the joint 21h where the ends of the plate material are joined is located on the first plate portion 61a of the fixed shield part 61, not on the second plate portion 61b of the fixed shield part 61.

[0148] 10, a pair of elastic support parts 80 are formed for each of the first portion 70a and the second portion 70b. That is, the first shield member 21 includes a total of four elastic support parts 80.

[0149] Similar to the first embodiment, the center portion 81c of the spring piece 81 extends in a substantially arc shape. However, as shown in Fig. 10, the substantially arc-shaped center portion 81c of the second embodiment is different from the first embodiment in that the arc has an angle of 180 degrees or more. Therefore, stress concentration in the center portion 81c can be suppressed.

[0150] In the first shield member 21 of the second embodiment, the movable shield portion 70 has a plurality of first contact portions 73a but does not have a second contact portion (see reference numeral 73b in FIG. 6).

[0151] (Second shield member 22) The second shield member 22 includes a fixed shield portion 161 and does not include a movable shield portion.

[0152] The fixed shield part 161 is cylindrical (specifically, rectangular cylindrical). The fixed shield part 161 includes a pair of first plate parts 161a and a pair of second plate parts 161b. The pair of first plate portions 161a face each other in the width direction. Specifically, each of the first plate portions 161a has a flat plate shape with its thickness direction aligned in the width direction. The pair of second plate portions 161b face each other in the front-rear direction. Specifically, each of the second plate portions 161b has a flat plate shape with a plate thickness direction aligned in the front-rear direction.

[0153] The second shield member 22 includes a plurality of connection portions 162a, 162b, and 162c. Each of the multiple connection portions 162a, 162b, and 162c is joined to a pad (not shown) formed on the upper surface of the first substrate 91 by soldering.

[0154] The multiple connection portions 162a, 162b, 162c include multiple first connection portions 162a protruding from the first plate portion 161a. The multiple connection portions 162a, 162b, 162c include multiple second connection portions 162b that protrude from the second plate portion 161b. The multiple connection parts 162a, 162b, 162c include multiple (four) third connection parts 162c whose plate thickness direction faces the up-down direction. The third connection parts 162c are connected to the first plate part 161a of the fixed shield part 161 via a bent part.

[0155] The second shield member 22 includes a plurality of contact portions 173 that come into contact with the plurality of contact portions 73 of the first shield member 21, respectively.

[0156] The contact portion 173 of the second shield member 22 is in the shape of a flat plate. The contact portion 173 has a planar plate surface that comes into contact with the contact portion 73 of the first shield member 21. Since the plate surface is the contact point, it is easy to apply plating to the contact point. The plate surface of the contact portion 173 has an area larger than the contact area between the contact portion 73 of the first shield member 21 and the contact portion 173 of the second shield member 22 . Therefore, even if the movable shield portion 70 of the first shield member 21 and the second shield member 22 are slightly misaligned in the XY plane, the two can be in contact with each other. In particular, in this embodiment, the first shield member 21 does not have a structure for displacing the movable shield portion 70 in the XY plane. In such a case, the above configuration is particularly effective. Moreover, when viewed from below, the contact portion 173 overlaps with the pad for the second signal terminal 50A formed on the lower surface of the second substrate 92 (see FIG. 11). In other words, the orthogonal projection of the contact portion 173 onto the lower surface of the second substrate 92 overlaps with the pad for the second signal terminal 50A formed on the lower surface of the second substrate 92. For this reason, the contact portion 173 can be formed large.

[0157] A curved portion 174 is formed on the outer side in the width direction of the contact portion 173 of the second shield member 22. The contact portion 173 is connected to the first plate portion 161a of the fixed shield portion 161 of the second shield member 22 via the curved portion 174. The contact portion 173 extends inward in the width direction from the curved portion 174. As a result, as shown in Fig. 11, the contact portion 173 is formed in a range spanning the inside and outside of the cylindrical fixed shield portion 161.

[0158] Alternatively, instead of the above configuration, a curved portion 174 may be formed on the inside in the width direction of the contact portion 173 of the second shield member 22. In this case, the contact portion 173 extends from the curved portion 174 outward in the width direction.

[0159] The flat contact portion 173 is not formed at a position corresponding to the second plate portion 161b of the rectangular tubular second shield member 22. Therefore, it is not necessary to form the contact portion 173 of the second shield member 22 so as to protrude outward in the front-rear direction beyond the second plate portion 161b. Therefore, the increase in the front-to-rear dimension of the second shield member 22 can be suppressed.

[0160] In this embodiment, the shield member 21 includes a base portion 60 that is not displaced relative to the attachment object 91 , and a movable shield portion 70 that is displaceable relative to the base portion 60 . Therefore, the movable shield part 70 which is displaceable relative to the object 91 to which the shielding is to be performed can shield the object to be shielded (the connector pair 11, 12).

[0161] 9, in this embodiment, the movable shield part 70 has a contact part 73 configured to come into contact with the contact object 22 (second shield member 22) by bringing the contact object 22 and the shield member 21 closer to each other in the first direction. The contact part 73 of the movable shield part 70 is configured to generate a contact pressure in the first direction (Z direction) by contact with the contact object 22. The movable shield part 70 is configured to be displaced in the first direction (Z direction) when the contact part 73 is pressed in the first direction (Z direction) by the contact object 22. This prevents a gap from occurring in the first direction between the contact object 22 and the shield member 21 or from becoming larger due to variation in the distance in the first direction between the attachment objects 91, 92 and the contact object 22.

[0162] In the first embodiment, the shield 21 is composed of only the first shield member 21. That is, the first shield member 21 shields the entire connector pair 11, 12 (see FIG. 3). For this reason, as shown in FIG. 2, the upper end of the first connector 11 is located lower than the upper end of the first shield member 21, and the vertical distance between the upper end of the first connector 11 and the upper end of the first shield member 21 is large. In this case, it is likely to be difficult to remove the cap 16 attached to the first connector 11. The cap 16 is a member having an adsorption surface 16a for adsorbing the connector when, for example, moving the connector to place it on a board. Therefore, in this embodiment, the first shielding member 21 cooperates with the second shielding member 22 to shield the connector pair 11, 12. Therefore, the upper end of the first shielding member 21 is likely to be located higher than the upper end of the first shielding member 21, and even if the upper end of the first connector 11 is located lower than the upper end of the first shielding member 21, the vertical distance between the upper end of the first connector 11 and the upper end of the first shielding member 21 is reduced. As a result, the task of removing the cap 16 attached to the first connector 11 is facilitated. In order to facilitate this operation, it is preferable that the suction surface 16a of the cap 16 is located above the upper end of the first shield member .

[0163] Here, the cap 16 that makes it even easier to remove the cap will be described with reference to FIG. FIG. 17 shows the connectors 11 and 21 with the shield members with the cap 16 attached. The cap 16 has a flat suction surface 16a and at least one operating portion 16b. Specifically, the at least one operation unit 16b includes a pair of operation units 16b, which are provided on one side and the other side in the front-rear direction with respect to the attraction surface 16a. Each operation portion 16b has a shape that protrudes upward from the suction surface 16a. Each operation portion 16b has a shape that allows a jig or the like to be hung from the outer side in the front-rear direction.

[0164] (Modification) FIG. 12 shows a shield structure 200A according to the first modification.

[0165] In the second embodiment, the contact portion 73 of the first shield member 21 is a convex contact portion, and the contact portion 173 of the second shield member 22 is a flat contact portion (see FIG. 10). 12 and 13, in Modification 1, the contact portion 73 of the first shield member 21 is a flat contact portion, and the contact portion 173 of the second shield member 22 is a convex contact portion. Even in this case, the movable shield portion 70 of the first shield member 21 and the second shield member 22 can be in contact with each other even if they are slightly misaligned in the XY plane.

[0166] Fig. 14 shows a shield structure 200B according to Modification 2. However, in Fig. 14, attachment objects 91 and 92 are omitted.

[0167] In the second modification, the base 60 of the first shielding member 21 is fixed to the first connector 11. That is, the base 60 of the first shielding member 21 has a portion (second plate portion 61b) that is fixed to the object to be shielded (the first connector 11). Therefore, the object to be shielded (first connector 11) and first shield member 21 can be handled as a single unit.

[0168] In addition, in the second modification, the second shielding member 22 is fixed to the second connector 12. That is, the second shielding member 22 has a portion that is fixed to the object to be shielded (the second connector 12).

[0169] 14, the first shield member 21 is fixed to the first connector 11 at both ends in the front-rear direction. Specifically, a pair of second plate portions 61b of the fixed shield portion 61 of the first shield member 21 are fixed to the fixed housing 41 of the first connector 11. Specifically, the fixed housing 41 has a pair of fixing portions 41a for fixing the first shielding member 21, and the first shielding member 21 has a pair of second plate portions 61b as fixed portions for being fixed to the fixed housing 41.

[0170] 14, the second shield member 22 is fixed to the second connector 12 at both ends in the front-rear direction. Specifically, a pair of second plate portions 161b of the fixed shield portion 161 of the second shield member 22 are fixed to the fixed housing 141 of the second connector 12. Specifically, the fixed housing 141 has a pair of fixing portions 141a for fixing the second shielding member 22, and the second shielding member 22 has a pair of second plate portions 161b as fixed portions for being fixed to the fixed housing 141.

[0171] [Regarding common use of shields] Next, the common use of a shield will be described with reference to FIG. 15 and FIG.

[0172] 15(A) and 16(A) both show a shield structure A. 15(B) and 16(B) both show shield structure B. Both shield structure A and shield structure B include common shields 21, 22. On the other hand, shield structure A includes connector pair 11A, 12A, and shield structure B includes connector pair 11B, 12B that is a different type from connector pair 11A, 12A. That is, although the shield structures A and B have different types (shapes, etc.) of the connector pair 11, 12 that are the objects to be shielded, the same shields 21, 22 are used.

[0173] In particular, the first shield member 21 and the second shield member 22 constituting the shields 21, 22 shown in Figures 15 and 16 do not have portions fixed to the connector pair 11, 12. Furthermore, the first shield member 21 and the second shield member 22 do not have portions that physically engage with the connector pair 11, 12. For this reason, there is little need to provide the shields 21, 22 with a structure corresponding to the structure of the connector pair 11, 12. As a result, it becomes easier to share the shield.

[0174] However, the shield can be shared even if the shielding member constituting the shield has a portion that is fixed to the object to be shielded. For example, in a third embodiment (see FIG. 14), the first shield member 21 is fixed to a fixed housing 41 of the first connector 11, and the second shield member 22 is fixed to a fixed housing 141 of the second connector 12. Even with this structure, the shields 21, 22 can be used in common between different types of connector pairs if the fixing portions 41a, 141a have a common structure.

[0175] However, according to a shielding member such as the first shielding member 21 described above, in which the movable shield portion 70 does not have a portion where it is fixed to the object to be shielded, it can be said that the shielding member can be easily standardized among multiple types of connectors.

[0176] The above-mentioned common use of the shield is possible even in the case where the shield is composed of only the first shield member (see the first embodiment).

[0177] By sharing the shield among multiple types of connector pairs, or by sharing the shield member among multiple types of connectors, it is possible to significantly reduce the cost of designing the shield member, the cost of establishing manufacturing facilities for manufacturing the shield member, etc. As a result, it is possible to realize inexpensive shield members and connectors with shield members, etc.

[0178] [Supplementary explanation of the above embodiment] Although the preferred embodiment of the connector of the present disclosure has been described above, the present disclosure is not limited thereto. The following description is a supplementary explanation for the sake of completeness.

[0179] In the above embodiment, the electronic components to be shielded are connector pairs, but the electronic components to be shielded in the present disclosure are not limited to this.

[0180] In the above embodiment, the cap 16 includes at least one operating part 16b, but the cap of the present disclosure is not limited to this and may not include an operating part. In this case, it is preferable that the suction surface of the cap is located above the upper end of the shield member when the cap is attached. In the above embodiment, the cap 16 includes at least one operating portion 16b, and at least a portion of the operating portion 16b is located above the upper end of the shielding member (see FIG. 17). This facilitates the task of removing the cap 16. However, the present disclosure is not limited to this, and the entire operating portion 16b may be located below the upper end of the shielding member. 17, the adsorption surface 16a of the cap is located below the upper end of the shield member 21. However, even when the cap is provided with an operation unit, the adsorption surface of the cap may be located above the upper end of the shield member. [Explanation of symbols]
