An object to be solved a second aspect of the disclosure is to simplify a structure of the shield member.
An object to be solved a third aspect of the disclosure is to realize an inexpensive connector with a shield member.
A shield member according to an aspect 1-1 is a shield member for shielding a shielding target, the shield member including a base portion that does not displace with respect to an attachment target; and a movable shield portion that is displaceable with respect to the base portion, in which the movable shield portion has a contact portion configured to come into contact with a contact target as a result of bringing the contact target and the shield member close to each other in a first direction, the contact portion of the movable shield portion is configured such that a contact pressure is generated in the first direction by the contact with the contact target, and the movable shield portion is configured to be displaced in the first direction when the contact portion is pressed by the contact target in the first direction.
The present aspect relates to a shield member for shielding a shielding target.
In the present aspect, the shield member includes a base portion that does not displace with respect to an attachment target, and a movable shield portion that is displaceable with respect to the base portion.
Therefore, the shielding target can be shielded by the movable shield portion that is displaceable with respect to the attachment target.
In the present aspect, the movable shield portion has a contact portion configured to come into contact with a contact target as a result of bringing the contact target and the shield member close to each other in a first direction. The contact portion of the movable shield portion is configured such that a contact pressure is generated in the first direction by the contact with the contact target. The movable shield portion is configured to be displaced in the first direction when the contact portion is pressed by the contact target in the first direction.
Therefore, it is possible to suppress generation of a gap in the first direction between the contact target and the shield member or increase of the gap due to variation in a distance in the first direction between the attachment target and the contact target.
The attachment target means an target to which the shield member is to be attached. In the embodiments described later, the attachment target is a substrate, but the attachment target of the present aspect is not limited thereto. In the embodiments described later, the shield member is directly attached to the attachment target (substrate) at the connecting portion. However, a case in which the shield member is indirectly attached to the attachment target via a member other than the shield member (for example, a housing of the connector) is also included in a case in which “the shield member is attached to the attachment target”.
The contact target means an target with which the shield member comes into contact. In the embodiments described later, the contact target is a mating substrate (second substrate) or a mating shield member (second shield member), but the contact target of the present aspect is not limited thereto. The contact target of the present aspect may be, for example, another component attached to the mating substrate, such as a housing included in the mating connector or a ground terminal included in the mating connector.
In the embodiments described later, the contact portion of the movable shield portion comes into contact with the contact target, whereby the shield member and the contact target are electrically connected, but the present aspect is not limited thereto.

At least one second terminal 50 includes a plurality of second signal terminals 50A. The plurality of second signal terminals 50A are configured by arranging a large number of pairs of second signal terminals 50A in the front-rear direction.
The contact portion 32 of the pair of first signal terminals 30A comes into contact with the contact portion 52 of the pair of second signal terminals 50A so as to sandwich the contact portion 52 from the outer side in the width direction (See
The contact pressure generated by the contact between the contact portion 32 of the first signal terminal 30A and the contact portion 52 of the second signal terminal 50A is generated in a direction in a plane (XY plane) perpendicular to the direction (Z direction) in which the first attachment target 91 and the second attachment target 92 face each other.
The at least one first terminal 30 includes a plurality of first power supply terminals 30B.
The at least one second terminal 50 includes a plurality of second power supply terminals 50B.
The plurality of first power supply terminals 30B are disposed in a region on one side in the front-rear direction and a region on the other side in the front-rear direction with respect to a region where the plurality of first signal terminals 30A are disposed. The same applies to the plurality of second power supply terminals 50B.
As can be seen from
The shield 21 includes only a first shield member 21.
Specifically, the first shield member 21 is formed by subjecting a conductive plate material to punching, bending, or the like.
The first shield member 21 has a substantially symmetrical structure in both the front-rear direction and the width direction.
The first shield member 21 has a tubular shape (specifically, a quadrangular tubular shape). The first shield member 21 accommodates the first connector 11 and the second connector 12 therein (see
As illustrated in
The base portion 60 is configured not to be displaced with respect to the first substrate 91.
The movable shield portion 70 is configured to be displaceable with respect to the base portion 60.
The at least one elastic support portion 80 elastically supports the movable shield portion 70.
The base portion 60 includes a fixed shield portion 61.
The fixed shield portion 61 has a tubular shape (specifically, a quadrangular tubular shape).
The fixed shield portion 61 includes a pair of first plate portions 61a and a pair of second plate portions 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 a plate thickness direction oriented in the width direction.
The pair of second plate portions 61b face each other in the front-rear direction. Specifically, each of the second plate portions 61b has a flat plate shape with the plate thickness direction oriented in the front-rear direction.
The base portion 60 includes a plurality of connecting portions 62a, 62b, and 62c.
Each of the plurality of connecting portions 62a, 62b, and 62c is bonded to a pad (not illustrated) formed on an upper surface of the first substrate 91 by soldering. As a result, the first shield member 21 is attached to the first substrate 91, and the first shield member 21 and the first substrate 91 are electrically connected.
The plurality of connecting portions 62a, 62b, and 62c include a plurality of first connecting portions 62a protruding from the first plate portion 61a.
Each of the first connecting portions 62a has a shape protruding downward with respect to a lower edge of the first plate portion 61a. A plurality of (four) first connecting portions 62a are formed for each of the first plate portions 61a.
The plurality of connecting portions 62a, 62b, and 62c include a plurality of second connecting portions 62b protruding from the second plate portion 61b.
Each of the second connecting portions 62b has a shape protruding downward with respect to a lower edge of the second plate portion 61b. A plurality of (two) second connecting portions 62b are formed for each of the second plate portions 61b.
A plate width dimension (dimension in the width direction) of the second connecting portion 62b is larger than a plate width dimension (dimension in the front-rear direction) of the first connecting portion 62a, and specifically, is three times or more the plate width dimension of the first connecting portion 62a.
Since the lower edge of the second plate portion 61b is positioned above the lower edge of the first plate portion 61a in the up-down direction, an up-down dimension of the second connecting portion 62b is larger than an up-down dimension of the first connecting portion 62a.
The plurality of connecting portions 62a, 62b, and 62c include a plurality of (four) third connecting portions 62c with the plate thickness direction oriented in the up-down direction.
The third connecting portion 62c is connected to the first plate portion 61a of the fixed shield portion 61 via a curved portion.
Since a plate thickness direction of the third connecting portion 62c is oriented in the up-down direction, a bonding area can be increased as compared with the first connecting portion 62a or the second connecting portion 62b, and an attachment strength of the first shield member 21 can be easily secured.
Positions of the third connecting portion 62c in the front-rear direction are positions corresponding to a front end and a rear end of the first plate portion 61a. This also makes it easy to secure the attachment strength of the first shield member 21.
The fixed shield portion 61 has a plurality of cutout portions 63.
The cutout portion 63 is formed in the first plate portion 61a of the fixed shield portion 61. Specifically, each of the pair of first plate portions 61a has two cutout portions 63.
The cutout portion 63 is a portion in which a part near the lower edge of the fixed shield portion 61 is cut out. A position of the cutout portion 63 is a position corresponding to the position where the first power supply terminal 30B of the first connector 11 is disposed. As a result, an appropriate distance is secured between the fixed shield portion 61 and the first power supply terminal 30B.
The position of the cutout portion 63 is a position adjacent to an inside of the third connecting portion 62c in the front-rear direction.
The movable shield portion 70 has a tubular shape (specifically, a quadrangular tubular shape).
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 the plate thickness direction oriented 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 the plate thickness direction oriented in the front-rear direction.
The first plate portion 71a of the movable shield portion 70 is positioned on the outer side of the first plate portion 61a of the fixed shield portion 61 in the width direction.
The second plate portion 71b of the movable shield portion 70 is positioned on the outer side of the second plate portion 61b of the fixed shield portion 61 in the front-rear direction.
In a state where the movable shield portion 70 is at an initial position (see
The movable shield portion 70 includes a supported portion 72 supported by the elastic support 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 portion 72a and the second portion 72b. Thus, the supported portion 72 is formed in a frame shape.
An upper end of the first portion 72a is connected to an upper end of the first plate portion 71a via a curved 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 curved portion. The second plate portion 71b is formed by bending a portion above the second portion 72b outward in the front-rear direction.
The movable shield portion 70 has a plurality of contact portions 73a and 73b.
Each of the plurality of contact portions 73a and 73b comes into contact with the second substrate 92 as a “connection target”. Specifically, each of the plurality of contact portions 73a and 73b comes into contact with a pad (not illustrated) formed on a lower surface of the second substrate 92. As a result, the first shield member 21 and the second substrate 92 are electrically connected.
The plurality of contact portions 73a and 73b include a plurality of first contact portions 73a protruding from the first portion 72a of the supported portion 72. Therefore, the first contact portion 73a is positioned on the same plane as the first plate portion 61a of the fixed shield portion 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 portion 73a has a substantially semicircular shape.
The plurality of contact portions 73a and 73b include a plurality of second contact portions 73b protruding from the second portion 72b of the supported portion 72. Therefore, the second contact portion 73b is positioned on the same plane as the first plate portion 61a of the fixed shield portion 61 and the second portion 72b.
A plurality of (two) second contact portions 73b are formed for each of the second portions 72b. The second contact portion 73b has a substantially semicircular shape.
Hereinafter, when the first contact portion 73a and the second contact portion 73b are not distinguished from each other, they are simply referred to as contact portions 73.
Although not illustrated, the pad formed on the lower surface of the second substrate 92 has an area larger than a contact area between the contact portions 73 of the first shield member 21 and the pad.
Therefore, even when the movable shield portion 70 of the first shield member 21 and the second substrate 92 are slightly displaced in the direction in the XY plane, it is possible to realize a state in which they are in contact with each other. In particular, in the present embodiment, the first shield member 21 does not have a structure for the movable shield portion 70 to be displaced in the direction in the XY plane. In such a case, the above configuration is particularly effective.
The 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 portion 80 connects the first plate portion 61a of the fixed shield portion 61 and the first portion 72a of the supported portion 72 of the movable shield portion 70.
The elastic support portion 80 is positioned on the same plane as the first plate portion 61a and the first portion 72a.
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 in an upward direction and an oblique direction on the outer side in the front-rear direction, an upper portion 81b extending in the upward direction and an oblique direction on an inner side in the front-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. The middle portion 81c extends in a substantially arc shape.
At a base end portion 80a of the elastic support portion 80, one spring piece 81 and the other spring piece 81 are integrated.
At a distal end portion 80b of the elastic support portion 80, one spring piece 81 and the other spring piece 81 are integrated.
As a result, concentration of stress on the base end portion 80a or the distal end portion 80b of the elastic support portion 80 is suppressed.
The first shield member 21 is made of a conductive material. Specifically, the first shield member 21 is made of one conductive plate.
The first shield member 21 has a tubular shape (specifically, a quadrangular tubular shape) as a whole by the fixed shield portion 61 and the movable shield portion 70.
As illustrated in
However, in the state illustrated in
Although the first connector 11 and the second connector 12 are normally connected even in the state illustrated in
Although not illustrated, when the distance between the first substrate 91 and the second substrate 92 is smaller than the distance illustrated in
Next, operations and effects of the present embodiment will be described.
In the present embodiment, the shield member 21 includes the base portion 60 that does not displace with respect to the attachment target 91 and the movable shield portion 70 that is displaceable with respect to the base portion 60.
Therefore, the shielding target (pair of connectors 11 and 12) can be shielded by the movable shield portion 70 that is displaceable with respect to the attachment target 91.
In the present embodiment, the movable shield portion 70 has the contact portion 73 configured to come into contact with the contact target 92 as a result of bringing the contact target 92 and the shield member 21 close to each other in the first direction. The contact portion 73 of the movable shield portion 70 is configured such that a contact pressure is generated in the first direction (Z direction) by the contact with the contact target 92. The movable shield portion 70 is configured to be displaced in the first direction (Z direction) when the contact portion 73 is pressed by the contact target 92 in the first direction (Z direction).
Therefore, it is possible to suppress generation of a gap in the first direction between the contact target 92 and the shield member 21 or increase of the gap due to variation in a distance in the first direction between the attachment targets 91 and 92 and the contact target 92.
Here, it is assumed that the contact portion 73 of the movable shield portion 70 is configured such that a contact pressure is generated in a direction in a plane perpendicular to the first direction by the contact with the contact target 92. In this case, when the position of the contact target 92 with respect to the movable shield portion 70 deviates from a predetermined position in the direction in the plane, there is a possibility that an appropriate contact pressure cannot be obtained.
Therefore, in the present embodiment, the contact portion 73 of the movable shield portion 70 is configured such that a contact pressure is generated in the first direction by the contact with the contact target 92.
Therefore, even when the position of the contact target 92 with respect to the movable shield portion 70 deviates from a predetermined position in the direction in the plane perpendicular to the first direction, it is easy to obtain an appropriate contact pressure.
In the present 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 target 92.
Therefore, it is compatible with a planar contact portion (pad not illustrated) of the contact target 92.
In the present embodiment, the movable shield portion 70 does not have a portion that is fixed to the shielding target (pair of connectors 11 and 12).
Therefore, it is not necessary to provide a structure for being fixed to the shielding target (pair of connectors 11 and 12) on the movable shield portion 70. As a result, the structure of the shield member 21 can be simplified.
In particular, in the present embodiment, the movable shield portion 70 does not have a portion that is physically engaged with the shielding target (pair of connectors 11 and 12).
Therefore, it is not necessary to provide a structure for physically engaging with the shielding target (pair of connectors 11 and 12) on the movable shield portion 70. As a result, the structure of the shield member 21 can be simplified.
Furthermore, in the present embodiment, the shield member 21 does not have a portion that is fixed to the shielding target (pair of connectors 11 and 12).
Therefore, it is not necessary to provide a structure for being fixed to the shielding target (pair of connectors 11 and 12) on the shield member 21. As a result, the structure of the shield member 21 can be simplified.
In a case in which the movable shield portion 70 and the like do not have a portion that is fixed to the shielding target, it is needless to say that it is unnecessary to provide a structure for fixing the movable shield portion 70 and the like on the shielding target. As a result, the structure of the shielding target can be simplified.
In the present embodiment, the base portion 60 includes the fixed shield portion 61 that shields the shielding target (pair of connectors 11 and 12).
Therefore, the shielding target (pair of connectors 11 and 12) can be shielded by both the fixed shield portion 61 that does not displace with respect to the attachment target 91 and the movable shield portion 70 that is displaceable with respect to the attachment target 91.
In the present embodiment, the fixed shield portion 61 has a tubular shape, and the movable shield portion 70 has a tubular shape.
Therefore, high shielding performance can be exhibited.
Furthermore, in the present embodiment, a part of the fixed shield portion 61 is disposed inside the movable shield portion 70. That is, it can be said that a part of one of the fixed shield portion 61 and the movable shield portion 70 is disposed inside the other.
Therefore, it is possible to suppress generation of a gap (gap in the up-down direction) between the tubular fixed shield portion and the tubular movable shield portion.
In the present embodiment, as illustrated in
Therefore, it is possible to prevent the elastic support portion 80 from being damaged or the like due to contact from the outside.
It is assumed that the contact portion 32 of the terminal 30 of the connector 11 is configured such that a contact pressure is generated in the first direction (Z direction) by the contact with the terminal 50 of the mating connector 12. In this case, in order to secure stable electrical connection, it is necessary to continuously press the connector 11 and the mating connector 12 strongly in the first direction, and both substrates (the substrate 91 and the mating substrate 92) are easily bent together with the pressing of the movable shield portion 70 and the contact target 92 in the first direction (Z direction).
Therefore, in the present embodiment, the contact portion 32 of the terminal 30 of the connector 11 is configured such that a contact pressure is generated in a direction in a plane perpendicular to the first direction by the contact with the terminal 50 of the mating connector 12.
Therefore, it is possible to suppress bending of both substrates (the substrate 91 and the mating substrate 92).
In the shield structure 200 according to the second embodiment, unlike the shield structure 100 according to the first embodiment, shields 21 and 22 include a second shield member 22 attached to the second substrate 92 in addition to the first shield member 21 attached to the first substrate 91. The first shield member 21 of the second embodiment shields the pair of connectors 11 and 12 in cooperation with the second shield member 22. Therefore, in the second embodiment, an target (contact target) with which the first shield member 21 comes into contact is the second shield member 22.
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, as in 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.
The first shield member 21 of the second embodiment has a configuration similar to that of the first shield member 21 of the first embodiment. Hereinafter, in the configuration of the first shield member 21 of the second embodiment, differences from the first shield member 21 of the first embodiment will be mainly described.
As illustrated in
The restriction mechanisms 65 and 75 are configured to restrict excessive displacement by a part and another part of the first shield member 21 abutting on each other. That is, the restriction mechanisms 65 and 75 are completed in the first shield member 21.
The specific structures of the restriction mechanisms 65 and 75 are as follows.
The restriction mechanisms 65 and 75 include an abutted portion 65 of the base portion 60 and an abutting portion 75 of the movable shield portion 70. When the movable shield portion 70 moves in a direction approaching the first attachment target 91 (−Z direction), the abutting portion 75 of the movable shield portion 70 abuts on the abutted portion 65 of the base portion 60.
The abutting portion 75 is formed at a lower end of each of the pair of second portions 72b of the supported portion 72 of the movable shield portion 70.
The abutted portion 65 is formed at an upper end of each of the pair of second plate portions 61b of the fixed shield portion 61.
The abutted portion 65 is formed above a portion of the fixed shield portion 61 connected to the elastic support portion 80 (upper edge of the first plate portion 61a). As a result, a distance (distance in the up-down direction) between the abutting portion 75 and the abutted portion 65 is smaller than an up-down dimension of the elastic support portion 80.
The abutting portion 75 is formed by bending a lower portion of the second portion 72b toward the inside of the shield 21 (inside in the front-rear direction).
The abutted portion 65 is formed by bending an upper portion of the second plate portion 61b toward the inside of the shield 21 (inside in the front-rear direction).
Accordingly, not plate end surfaces but plate surfaces are brought into contact with each other. As a result, excessive displacement of the movable shield portion 70 can be restricted more reliably.
The fixed shield portion 61 has an extension portion 66 for closing a gap between the first plate portion 71a and the second plate portion 71b of the movable shield portion 70.
The extension portion 66 is a portion of the fixed shield portion 61 near the curved portion connecting 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 in which a part of the fixed shield portion 61 is extended in the upward direction.
(First Portion 70a and Second Portion 70b that are Displaceable Independently of Each Other)
The movable shield portion 70 of the first shield member 21 includes a first portion 70a and a second portion 70b that are displaceable independently of each other. Therefore, even when the contact target 92 is inclined with respect to a predetermined state, a favorable contact state between the movable shield portion 70 and the contact target 92 can be realized.
The first portion 70a constitutes one side of the movable shield portion 70 in the front-rear direction.
The second portion 70b constitutes the other side of the movable shield portion 70 in the front-rear direction.
The first portion 70a and the second portion 70b have substantially the same structure.
The first shield member 21 is formed by subjecting one plate material to punching, bending, or the like. In the first shield member 21, one part and the other part are connected as a plate. This point is similar to the first shield member 21 of the first embodiment.
In this regard, in the first shield member 21 of the second embodiment, the joint portion 21h where end portions of the plate material as the material are joined to each other is positioned not in the second plate portion 61b of the fixed shield portion 61 but in the first plate portion 61a of the fixed shield portion 61.
As illustrated in
The second embodiment is similar to the first embodiment in that the middle portion 81c of the spring piece 81 extends in a substantially arc shape. However, as illustrated in
In the first shield member 21 of the second embodiment, the movable shield portion 70 has the plurality of first contact portions 73a, but does not have the second contact portion (see reference numeral 73b in
The second shield member 22 includes a fixed shield portion 161 and does not include a movable shield portion.
The fixed shield portion 161 has a tubular shape (specifically, a quadrangular tubular shape).
The fixed shield portion 161 includes a pair of first plate portions 161a and a pair of second plate portions 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 the plate thickness direction oriented 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 the plate thickness direction oriented in the front-rear direction.
The second shield member 22 includes a plurality of connecting portions 162a, 162b, and 162c.
Each of the plurality of connecting portions 162a, 162b, and 162c is bonded to a pad (not illustrated) formed on an upper surface of the first substrate 91 by soldering.
The plurality of connecting portions 162a, 162b, and 162c include a plurality of first connecting portions 162a protruding from the first plate portion 161a.
The plurality of connecting portions 162a, 162b, and 162c include a plurality of second connecting portions 162b protruding from the second plate portion 161b.
The plurality of connecting portions 162a, 162b, and 162c include a plurality of (four) third connecting portions 162c with the plate thickness direction oriented in the up-down direction. The third connecting portion 162c is connected to the first plate portion 161a of the fixed shield portion 161 via a curved portion.
The second shield member 22 includes a plurality of contact portions 173 that come into contact with each of the plurality of contact portions 73 of the first shield member 21.
The contact portion 173 of the second shield member 22 has a flat plate shape. The contact portion 173 is a planar plate surface and comes into contact with the contact portion 73 of the first shield member 21. Since the plate surface is a contact portion, plating is easily applied to the contact portion.
The plate surface of the contact portion 173 has an area larger than a 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 when the movable shield portion 70 of the first shield member 21 and the second shield member 22 are slightly displaced in the direction in the XY plane, it is possible to realize a state in which they are in contact with each other. In particular, in the present embodiment, the first shield member 21 does not have a structure for the movable shield portion 70 to be displaced in the direction in the XY plane. In such a case, the above configuration is particularly effective.
When viewed from below, the contact portion 173 overlaps a pad for the second signal terminal 50A formed on the lower surface of the second substrate 92 (see
A curved portion 174 is formed on the outer side of the contact portion 173 of the second shield member 22 in the width direction. 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 illustrated in
Instead of the above configuration, the curved portion 174 may be formed on the inner side in the width direction of the contact portion 173 of the second shield member 22. In this case, the contact portion 173 extends outward in the width direction from the curved portion 174.
The contact portion 173 having a flat plate shape is not formed at a position corresponding to the second plate portion 161b in the second shield member 22 having a quadrangular tubular shape. 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 of the second plate portion 161b.
Therefore, it is possible to suppress an increase in a front-rear dimension of the second shield member 22.
In the present embodiment, the shield member 21 includes the base portion 60 that does not displace with respect to the attachment target 91 and the movable shield portion 70 that is displaceable with respect to the base portion 60.
Therefore, the shielding target (pair of connectors 11 and 12) can be shielded by the movable shield portion 70 that is displaceable with respect to the attachment target 91.
In the present embodiment, as illustrated in
Therefore, it is possible to suppress generation of a gap in the first direction between the contact target 22 and the shield member 21 or increase of the gap due to variation in a distance in the first direction between the attachment targets 91 and 92 and the contact target 22.
Meanwhile, in the first embodiment, the shield 21 includes only the first shield member 21. That is, the first shield member 21 shields the entire pair of connectors 11 and 12 (see
Therefore, in the present embodiment, the first shield member 21 shields the pair of connectors 11 and 12 in cooperation with the second shield member 22.
Therefore, the upper end of the first shield member 21 is easily positioned above the upper end of the first shield member 21, and even when the upper end of the first connector 11 is positioned below the upper end of the first shield member 21, the distance in the up-down direction between the upper end of the first connector 11 and the upper end of the first shield member 21 becomes small. As a result, the work of detaching the cap 16 mounted on the first connector 11 is facilitated.
From the viewpoint of facilitating the work, the suction surface 16a of the cap 16 is preferably positioned above the upper end of the first shield member 21.
Here, the cap 16 that further facilitates the work of detaching the cap will be described with reference to
The cap 16 has a planar suction surface 16a and at least one operation portion 16b.
Specifically, the at least one operation portion 16b includes a pair of operation portions 16b. The pair of operation portions 16b are provided on one side and the other side in the front-rear direction with respect to the suction surface 16a.
Each operation portion 16b has a shape protruding upward with respect to the suction surface 16a. Each operation portion 16b has a shape capable of hooking a jig or the like from the outside in the front-rear direction.
In the second embodiment, the contact portion 73 of the first shield member 21 is a contact portion having a convex shape, and the contact portion 173 of the second shield member 22 is a contact portion having a flat plate shape (see
On the other hand, in the first modification, as illustrated in
In the second modification, the base portion 60 of the first shield member 21 is fixed to the first connector 11. That is, the base portion 60 of the first shield member 21 has a portion (second plate portion 61b) that is fixed to the shielding target (first connector 11).
Therefore, the shielding target (first connector 11) and the first shield member 21 can be handled integrally.
In the second modification, the second shield member 22 is fixed to the second connector 12. That is, the second shield member 22 has a portion that is fixed to the shielding target (second connector 12).
As illustrated in
Specifically, the fixed housing 41 has a pair of fixing portions 41a for fixing the first shield member 21, and the first shield member 21 has a pair of second plate portions 61b as fixed portions for being fixed to the fixed housing 41.
As illustrated in
Specifically, the fixed housing 141 has a pair of fixing portions 141a for fixing the second shield member 22, and the second shield member 22 has a pair of second plate portions 161b as fixed portions for being fixed to the fixed housing 141.
Next, commonality of the shields will be described with reference to
Both the shield structure A and the shield structure B include common shields 21 and 22. On the other hand, the shield structure A includes a pair of connectors 11A and 12A, and the shield structure B includes a pair of connectors 11B and 12B different in type from the pair of connectors 11A and 12A.
That is, in the shield structure A and the shield structure B, the same shields 21 and 22 are used although the types (shapes and the like) of the pair of connectors 11 and 12 as shielding targets are different.
In particular, the first shield member 21 and the second shield member 22 constituting the shields 21 and 22 illustrated in
However, the commonality of the shields is possible even in a case in which the shield member constituting the shield has a portion that is fixed to the shielding target.
For example, in a third embodiment (see
However, like the first shield member 21 described so far, the shield member in which the movable shield portion 70 does not have a portion that is fixed to the shielding target can be said to facilitate commonality of the shield member among the plurality of types of connectors.
The above-described commonality of the shields is also possible in a case in which the shield is formed of only the first shield member (see the first embodiment).
By making the shield common among the plurality of types of the pair of connectors or making the shield member common among the plurality of types of connectors, the cost of designing the shield member, the cost of providing manufacturing equipment for manufacturing the shield member, and the like can be greatly reduced. As a result, an inexpensive shield member, a connector with a shield member, and the like can be realized.
Although the preferred embodiments of the connector of the disclosure have been described above, the disclosure is not limited thereto. The following description is a supplementary description just in case.
In the embodiments, the electronic component as the shielding target is a pair of connectors, but the electronic component as the shielding target of the disclosure is not limited thereto.
In the embodiments, the cap 16 includes at least one operation portion 16b, but the cap of the disclosure is not limited thereto, and not necessarily includes an operation portion. In this case, it is preferable that the suction surface of the cap is located above the upper end of the shield member in a state where the cap is mounted.
In the embodiments, the cap 16 includes at least one operation portion 16b, and at least a part of the operation portion 16b is located above the upper end of the shield member (see
