A first object of the present disclosure is to provide a connector that includes a movable housing and that is capable of appropriately shielding the movable housing.
A second object of the present disclosure is to provide a connector that includes a housing having a tubular portion and that can easily and securely hold a shield.

First Aspect
The connector of aspect 1-1 is a connector comprising a terminal, a housing, and a shield, wherein the housing comprises a fixed housing whose position is fixed relative to an object to which the connector is attached, and a movable housing which is movable relative to the fixed housing, and the shield has a grounding portion connected to the object to which the connector is attached, a movable shield portion which is electrically connected to the grounding portion and attached to the movable housing, and a shield spring portion which is located between the grounding portion and the movable shield portion and is deformable.

In the above aspect, the connector includes a terminal and a housing. The housing includes a fixed housing whose position is fixed with respect to an attachment object, and a movable housing that is movable with respect to the fixed housing.
The connector further includes a shield having a ground portion connected to the attachment object and a movable shield portion electrically connected to the ground portion and attached to the movable housing, so that grounding is performed at the ground portion and the movable housing is shielded by the movable shield portion electrically connected to the ground portion.
In addition, the shield has a deformable shield spring portion located between the ground portion and the movable shield portion, so that the deformation of the shield spring portion allows the movable shield portion to move relative to the ground portion, thereby allowing the movable housing to be appropriately shielded in a connector having a movable housing.

In the connector according to aspect 1-2, in aspect 1-1, the shield has a fixed shield part that is attached to the fixed housing.

In the above aspect, the shield has a fixed shield portion that is attached to the fixed housing.
Therefore, noise countermeasures can be improved compared to a configuration in which the shield does not have a fixed shield part.

The connector according to aspect 1-3 is the connector according to aspect 1-2, in which the shield includes a first shield and a second shield separate from the first shield, the first shield has the fixed shield portion, and the second shield has the movable shield portion.

It can be difficult to manufacture complex, wide-area shields from a single sheet of metal.
In the above aspect, the shield includes a first shield and a second shield separate from the first shield. The first shield has a fixed shield portion, and the second shield has a movable shield portion.
For this reason, the movable shield part attached to the movable housing and the fixed shield part attached to the fixed housing are formed as a first shield and a second shield that are separate from each other, respectively, making it easy to form a shield that covers a complex and wide area.

The connector according to aspect 1-4 is the connector according to aspect 1-3, in which the second shield has the shield spring portion and a second side contact portion that contacts the first shield, and the shield spring portion is located between the movable side shield portion and the second side contact portion.

In the above aspect, the second shield has a shield spring portion and a second contact portion that contacts the first shield. The shield spring portion is located between the movable shield portion and the second contact portion.
Therefore, compared to an embodiment in which the first shield has a shield spring portion, it is possible to prevent the first shield from becoming complicated. When the first shield can be prevented from becoming complicated, the degree of freedom in designing the fixed shield portion of the first shield is improved.

The connector according to aspect 1-5 is the connector according to aspect 1-4, in which the second shield has a fixed-side held portion that is held by the fixed housing, and the fixed-side held portion is located on the opposite side of the shield spring portion from the movable-side shield portion.

In the above aspect, the second shield has a fixed-side held portion that is held by the fixed housing, and the fixed-side held portion is located on the opposite side of the shield spring portion from the movable-side shield portion.
This prevents the second side contact portion of the second shield from moving together with the movable housing, and as a result, prevents sliding between the second side contact portion of the second shield and the first shield.

The connector according to aspect 1-6 is the connector according to aspect 1-5, in which the fixed-side held portion is located between the second-side contact portion and the shield spring portion.

In the above aspect, the fixed-side held portion is located between the second-side contact portion and the shield spring portion.
This further prevents the second side contact portion of the second shield from moving together with the movable housing, and as a result, the sliding between the second side contact portion of the second shield and the first shield is further prevented.

In the connector according to aspect 1-7, in aspect 1-5 or 1-6, the second shield has an elastic support portion that elastically supports the second side contact portion relative to the fixed side held portion.

In the above aspect, the second shield has the elastic support portion that elastically supports the second side contact portion with respect to the fixed side held portion.
Therefore, even if a deviation occurs in the position where the fixed-side held portion of the second shield is held, the contact state between the second contact portion and the first shield is less likely to be affected.

The connector according to aspect 1-8 is the connector according to aspect 1-7, in which the fixed-side held portion of the second shield is held by being pressed into the fixed housing from below, and the elastic support portion extends obliquely downward from above the fixed-side held portion.

In the above aspect, the fixed-side held portion of the second shield is held by being press-fitted into the fixed housing from below. The elastic support portion extends obliquely downward from above the fixed-side held portion.
Therefore, compared to a configuration in which the elastic support portion extends obliquely upward from above the fixed-side held portion, it is easier to ensure the vertical dimension of the fixed-side held portion.

The connector according to aspect 1-9 is any of aspects 1-4 to 1-8, in which the first shield has a first side contact portion that contacts the second side contact portion of the second shield, the first side contact portion has an outer surface facing the outside of the connector and an inner surface facing the inside of the connector, and the second side contact portion contacts the inner surface of the first side contact portion.

In the above aspect, the first shield has a first side contact portion that contacts the second side contact portion of the second shield. The first side contact portion has an outer surface facing the outside of the connector and an inner surface facing the inside of the connector. The second side contact portion contacts the inner surface of the first side contact portion.
This reduces the likelihood of the second contact portion being exposed to the outside of the connector, thereby reducing the risk of damage to the second contact portion.

The connector according to aspect 1-10 is any of aspects 1-4 to 1-9, in which the first shield has a first side contact portion that contacts the second side contact portion of the second shield and a fixed side held portion that is held by the fixed housing, and the fixed side held portion of the first shield also serves as the first side contact portion.

In the above embodiment, the first shield has a fixed-side held portion that is held by the fixed housing. The fixed-side held portion of the first shield also serves as the first-side contact portion. This makes it difficult for the position of the first-side contact portion to shift, and the contact state between the first shield and the second shield is stable.

<Second aspect>
The connector of aspect 2-1 is a connector comprising a housing and a shield, wherein the housing has a cylindrical portion formed with an insertion space into which a connection object is inserted from above, and the shield has a main body portion covering the cylindrical portion from the outside in the width direction and a held portion held by the housing, and the position at which the held portion is held is outboard in the front-to-rear direction of the insertion space.

In the above aspect, the connector includes a housing having a cylindrical portion formed with an insertion space into which a connection object is inserted from above.
The connector also includes a shield having a main body portion that covers the tubular portion from the outside in the width direction, and a held portion that is held by the housing.
Here, the position at which the held portion is held is outboard of the insertion space in the front-rear direction, so that the shield can be held by the portion of the cylindrical portion that has a larger width dimension, making it easy to hold the shield reliably.
In the embodiment described later, an example in which a pair of held parts of the shield are provided on the front and rear sides will be described, but the above aspect is not limited to this. In other words, an aspect in which the held part is provided only on one side, the front or rear, is also included in the above aspect (aspect 2-1).

In the connector according to aspect 2-2, in aspect 2-1, the retained portion is located widthwise inward of the main body portion.

In the above embodiment, the held portion is located inward in the width direction from the main body portion. This allows the position in the housing that holds the held portion to be shifted inward in the width direction. This allows the shield to be properly held in the housing while keeping the width dimension of the housing small.

In the connector according to aspect 2-3, in aspect 2-1 or 2-2, the housing has a holding portion that holds the held portion, and a lower recess formed below the holding portion and recessed inward in the width direction, and the held portion is press-fitted into the holding portion from below.

In the above aspect, the housing has a holding portion that holds the held portion, and a lower recess that is formed below the holding portion and recessed inward in the width direction. The held portion of the shield is press-fitted from below into the holding portion of the housing.
Therefore, unlike the embodiment in which the press-fit direction of the held portion into the housing is the widthwise inward, the widthwise inner portion of the front-to-rear wall of the housing (the portion that is front-to-rear more outer than the insertion space) can be easily used for other purposes (e.g., holding a power terminal).

The connector according to aspect 2-4 is any one of aspects 2-1 to 2-3, in which the housing has an outer surface on the width direction that is recessed toward the inside in the width direction and has a recessed arrangement in which the main body is arranged.

In the above aspect, the housing has an outer surface in the width direction of the housing that is recessed inward in the width direction and has an arrangement recess in which the main body of the shield is arranged.
This allows for a reduction in size in the width direction.

The connector according to aspect 2-5 is any of aspects 2-1 to 2-4, in which the housing has a peeling prevention portion disposed above the upper end of the main body.

In the above embodiment, the housing has a peeling prevention part that is disposed above the upper end of the main body. This prevents the shield from peeling off when connecting to a connection object, etc.

The connector according to aspect 2-6 is any of aspects 2-1 to 2-5, in which the main body has a tip extension portion in which the upper end of the main body is extended upward.

In the above embodiment, the main body has a tip extension in which the upper end of the main body is partially extended upward. This allows the effective engagement length to be increased.

The connector according to aspect 2-7 is any of aspects 2-1 to 2-4, in which the housing has a peeling prevention part that is arranged above the upper end of the main body, the main body has a tip extension part that is a partial upward extension of the upper end of the main body, and the peeling prevention part is not formed in a position corresponding to the tip extension part of the main body.

In the above embodiment, the peeling prevention portion is not formed at a position corresponding to the tip extension of the main body portion. This allows the tip extension portion to be extended upward a long distance, making it easier to ensure the effective engagement length.

<Third aspect>
The connector of the 3-1st aspect is a connector comprising a housing and a shield, wherein the housing has a tubular portion formed with an insertion space into which a connection object is inserted from above, and a placement recess in which the widthwise outer surface of the housing is recessed toward the widthwise inner side, and the shield has a main body portion that is placed in the placement recess to cover the tubular portion from the widthwise outer side.

In the above aspect, the connector includes a housing and a shield. The housing has a cylindrical portion having an insertion space into which a connection object is inserted from above, and a recessed arrangement portion in which an outer surface of the housing in the width direction is recessed toward the inside in the width direction. The shield has a main body portion that is disposed in the recessed arrangement portion to cover the cylindrical portion from the outside in the width direction.
Therefore, it is possible to achieve a smaller size in the width direction compared to a configuration in which a shield is disposed without forming an arrangement recess.
Therefore, according to the above aspect, a connector having a shield is provided that can be easily miniaturized.

In the embodiment described below, an example will be described in which the housing is a movable housing and the connector is a floating connector, but the above aspect is not limited to this. The housing may be a fixed housing.
In addition, in the embodiment described below, an example is described in which the shield has a held portion that is held in the housing, and the position at which the held portion is held is further outward in the front-to-rear direction than the insertion space, but the above aspect is not limited to this.

<Fourth aspect>
A connector according to a 4-1 aspect is a connector comprising a first housing, a second housing movable relative to the first housing, and a conductive member, wherein the conductive member comprises a first conductive member and a second conductive member separate from the first conductive member, the first conductive member has a held portion held by the first housing, and the second conductive member has a first housing side held portion held by the first housing, a second housing side held portion held by the second housing, a deformable spring portion located between the first housing side held portion and the second housing side held portion, a contact portion in contact with the first conductive member, and an elastic support portion that elastically supports the contact portion against the first housing side held portion.

In the above aspect, the connector includes a first housing and a second housing movable relative to the first housing.
The connector also includes a conductive member. The conductive member includes a first conductive member and a second conductive member that is separate from the first conductive member.

Here, the second conductive member has a spring portion, a contact portion, and an elastic support portion.
Since the contact portion of the second conductive member contacts the first conductive member, electrical continuity between the first conductive member and the second conductive member is ensured. Also, the deformation of the spring portion of the second conductive member allows the second housing to move relative to the first housing. Furthermore, since the elastic support portion of the second conductive member elastically supports the contact portion with respect to the first housing side held portion, electrical continuity between the first conductive member and the second conductive member is stabilized.
According to the above aspect, not only can the conductive member spanning between the first housing and the second housing be constructed of separate members (the first conductive member and the second conductive member), but the conductive connection between the first conductive member and the second conductive member can be stabilized.

In the embodiment described below, an example is described in which the first housing is a fixed housing and the second housing is a movable housing, but the above aspect is not limited to this. For example, the first housing may be a movable housing and the second housing may be a fixed housing.
In the embodiment described below, the conductive member is a shield, but the embodiment is not limited to this. The conductive member may be a terminal such as a signal terminal, a power terminal, a ground terminal, or a ground terminal.

The connector 1 according to the embodiment is described below.

The arrows X, Y, and Z shown in each figure are directional concepts based on the connector 1 and its components. The +X direction is the connector's forward direction, the +Y direction is the connector's width direction to one side, and the +Z direction is the connector's upward direction. When simply referring to the forward/backward direction, width direction, and up/down direction, they mean the connector's forward/backward direction, connector's width direction, and connector's up/down direction.

<General configuration of connector 1>
FIG. 1 is a perspective view of the connector 1, and FIGS. 2 and 3 are exploded perspective views of the connector 1. As shown in FIG.
The connector 1 comprises a fixed housing 2, a movable housing 3, a plurality of first terminals 4, and a plurality of third terminals 5.

The fixed housing 2 and the movable housing 3 are made of an insulating material such as synthetic resin.

The fixed housing 2 holds a portion of the first terminal 4 and the third terminal 5 (fixed side held portion 42, fixed side held portion 52, see FIG. 8). The fixed housing 2 is fixed to a board (not shown) via the first terminal 4 and the third terminal 5, and is immovable relative to the board. The fixed housing 2 is frame-shaped, and forms a space (internal space 21) inside. The movable housing 3 is disposed in the internal space 21 of the fixed housing 2.

The movable housing 3 holds a portion of the first terminal 4 and the third terminal 5 (movable side held portion 44, movable side held portion 54). The movable housing 3 is disposed in the space inside the frame-shaped fixed housing 2 (internal space 21) and is movable relative to the board and the fixed housing 2. The movable housing 3 has an insertion space 31 that opens upward. A portion of the mating connector as the "connection object" is inserted into the insertion space 31.

As shown in FIG. 8, each first terminal 4 has a fixed-side held portion 42 held by the fixed housing 2, a movable-side held portion 44 held by the movable housing 3, and an intermediate elastic portion 43 between the fixed-side held portion 42 and the movable-side held portion 44. The intermediate elastic portion 43 elastically deforms to allow the movable housing 3 to move relative to the fixed housing 2.

Each third terminal 5 has a fixed-side held portion 52 held by the fixed housing 2, a movable-side held portion 54 held by the movable housing 3, and an intermediate elastic portion 53 between the fixed-side held portion 52 and the movable-side held portion 54. The intermediate elastic portion 53 elastically deforms to allow the movable housing 3 to move relative to the fixed housing 2.

The connector 1 also includes shields 6 and 7 for blocking noise. The shields 6 and 7 are composed of a first shield 6 and a pair of second shields 7 that are separate from the first shield 6.

<Detailed configuration of connector 1>
Next, the detailed configuration of the connector 1 will be described.

<First terminal 4>
The first terminals 4 each have the same shape. The first terminals 4 are manufactured by subjecting a plate material to processes such as punching and bending. The first terminals 4 are composed of a plurality of first terminals 4 arranged in the front-rear direction (pitch direction) on one side in the width direction (row direction) and a plurality of first terminals 4 arranged in the front-rear direction (pitch direction) on the other side in the width direction (row direction). The first terminals 4 on one side in the width direction and the first terminals 4 on the other side in the width direction are arranged such that their contact portions 46 face each other.

As shown in FIG. 8, the first terminal 4 has, from one end to the other end, a substrate fixing portion 41, a fixed side held portion 42, an intermediate elastic portion 43, a movable side held portion 44, a tip elastic portion 45, and a contact portion 46, which are integral with each other.

The substrate fixing portion 41 is fixed to the substrate. The substrate fixing portion 41 extends inward in the width direction from one end to the other end.

The fixed-side held portion 42 is held by the fixed housing 2. The fixed-side held portion 42 extends upward and has press-fit protrusions on both outer sides in the front-to-rear direction, which is the plate width direction. The fixed-side held portion 42 is press-fit into the fixed housing 2 from below.

The intermediate elastic portion 43 is configured to be elastically deformable and has a first curved portion 43A, a straight portion 43B, and a second curved portion 43C.
The first curved portion 43A is formed by bending the portion on the other end side of the fixed-side held portion 42 in the plate thickness direction. The straight portion 43B extends linearly downward in a direction inclined inward in the width direction. The second curved portion 43C is formed by bending the portion on the other end side of the straight portion 43B in the plate thickness direction. The second curved portion 43C connects the straight portion 43B and the movable-side held portion 44. The straight portion 43B has a width expansion portion 43B1. The width dimension of the width expansion portion 43B1 (the dimension in the front-rear direction of the connector, which is the pitch direction) is larger than the width dimensions of the first curved portion 43A and the second curved portion 43C.

The movable-side held portion 44 is held by the movable housing 3. The movable-side held portion 44 extends upward and has press-fit protrusions on both outer sides in the front-to-rear direction, which is the plate width direction. The movable-side held portion 44 is press-fit into the movable housing 3 from below.

The tip elastic portion 45 elastically supports the contact portion 46 so that the contact portion 46 can be displaced relative to the movable housing 3. The tip elastic portion 45 has a first extension portion 45A on one end side and a second extension portion 45B on the other end side. The first extension portion 45A and the second extension portion 45B both extend in a direction that is inclined inward in the width direction toward the upward direction, but the first extension portion 45A has a larger angle of inclination toward the upward direction than the second extension portion 45B.

The contact portion 46 comes into contact with a second terminal (not shown) of a mating connector, which is the "connection object." The contact portion 46 is curved so as to be convex toward the inside in the width direction. A curved portion 46A is formed between the contact portion 46 and the tip elastic portion 45 so as to cause the contact portion 46 to protrude toward the inside in the width direction.

<Third terminal 5>
The third terminal 5 is manufactured by subjecting a plate material to processes such as punching and bending.
The multiple third terminals 5 are composed of a pair of third terminals 5 on one side in the front-rear direction and a pair of third terminals 5 on the other side in the front-rear direction.

The third terminal 5 has, from one end to the other end, a substrate fixing portion 51, a fixed side held portion 52, an intermediate elastic portion 53, a movable side held portion 54, a tip elastic portion 55, and a contact portion 56.

The substrate fixing part 51 is fixed to the substrate.

The fixed side held portion 52 is held by the fixed housing 2. The fixed side held portion 52 has a press-fit portion 52A that is press-fitted into the fixed housing 2. The press-fit portion 52A is formed to protrude upward and has a locking protrusion only on the inner side in the connector width direction, which is the plate width direction. The press-fit portion 52A of the fixed side held portion 52 is press-fitted from below into the third terminal holding portion 25B (see Figure 10) of the fixed housing 2.

The intermediate elastic portion 53 is configured to be elastically deformable. The intermediate elastic portion 53 has a first straight portion 53A, a first curved portion 53B, and a second straight portion 53C. The first straight portion 53A, the first curved portion 53B, and the second straight portion 53C form a mountain-shaped portion that is convex upward. The first straight portion 53A extends linearly upward, and the second straight portion 53C extends linearly downward. The second straight portion 53C is located at the same position in the front-rear direction as the first straight portion 53A.
Furthermore, the intermediate elastic portion 53 has a second curved portion 53D. The second curved portion 53D connects the second straight portion 53C and the movable-side held portion 54.
The thickness direction of the intermediate elastic portion 53 is oriented in the pitch direction. That is, the curved portions (the first curved portion 53B and the second curved portion 53D) of the intermediate elastic portion 53 are formed by punching, not by bending.

The movable-side held portion 54 is held by the movable housing 3. The movable-side held portion 54 extends upward and has press-fit protrusions on both outer sides in the connector width direction, which is the plate width direction. The movable-side held portion 54 is press-fit into the movable housing 3 from below.

The tip elastic portion 55 elastically supports the contact portion 56 so that the contact portion 56 can be displaced relative to the movable housing 3. The tip elastic portion 55 has a first extension portion 55A on one end side and a second extension portion 55B on the other end side. The first extension portion 55A and the second extension portion 55B both extend upward in a direction that is inclined outward in the front-to-rear direction, but the first extension portion 55A has a larger angle of inclination relative to the upward direction than the second extension portion 55B. The plate width dimension (dimension in the connector width direction) of the tip elastic portion 55 gradually decreases from one end side to the other end side.

The contact portion 56 comes into contact with a fourth terminal (not shown) of the mating connector. The contact portion 56 is curved so as to be convex toward the outside in the pitch direction. A curved portion 56A is formed between the contact portion 56 and the tip elastic portion 55 so as to cause the contact portion 56 to protrude toward the outside in the pitch direction.

<Fixed housing 2>
9 and 10 are perspective views of the fixed housing 2. FIG.

The fixed housing 2 has a pair of front-rear direction portions 22 that face each other in the front-rear direction with the internal space 21 between them, and a pair of width direction portions 23 that face each other in the width direction with the internal space 21 between them. The pair of front-rear direction portions 22 and the pair of width direction portions 23 form the frame-shaped fixed housing 2.

The fixed housing 2 has a restraining recess 24 as a "restraining portion" that restrains a part of the movable housing 3 (the front-rear protrusion 36, which is the "restrained portion"; see FIG. 11). The restraining recess 24 is formed in each of the pair of front-rear portions 22. The restraining recess 24 is a recess formed in the lower part of the front-rear portion 22, and is open downward and on both the front-rear and rear-rear sides.

The fixed housing 2 has a first terminal holding portion 25A that holds the fixed-side held portion 42 of the first terminal 4. The first terminal holding portion 25A is a groove that extends in the vertical direction and is formed on the inner widthwise surfaces of the pair of widthwise portions 23. The fixed-side held portion 42 of the first terminal 4 is pressed into the groove that serves as the first terminal holding portion 25A from below.

The fixed housing 2 has a third terminal holding portion 25B that holds the fixed side held portion 52 of the third terminal 5. The third terminal holding portion 25B is located further outward in the pitch direction than the multiple first terminal holding portions 25A. The third terminal holding portion 25B is a through hole that is formed in the pair of width direction portions 23 and extends in the vertical direction. The press-fit portion 52A of the fixed side held portion 52 of the third terminal 5 is press-fitted from below into the through hole that serves as the third terminal holding portion 25B.

The fixed housing 2 has a protective wall 26 for protecting the intermediate elastic portion of the terminal.
5, the intermediate elastic portion 43 of the first terminal 4 and the intermediate elastic portion 53 of the third terminal 5 are disposed on the outer side in the width direction of the movable housing 3, and therefore the protective wall 26 is formed on the width direction portion 23. The protective wall 26 has a side wall 26A that protects the intermediate elastic portion 43 of the first terminal 4 and the intermediate elastic portion 53 of the third terminal 5 from the outer side in the width direction, and a top wall 26B that protects the intermediate elastic portion 43 of the first terminal 4 and the intermediate elastic portion 53 of the third terminal 5 from above. The top wall 26B extends inward in the width direction from the upper end of the side wall 26A.

In addition, the protective wall 26 has a reinforcing portion 26C that reinforces the top wall 26B.
The reinforcing portion 26C is formed at both ends in the connector front-rear direction, which is the extension direction of the protective wall 26. The reinforcing portion 26C connects the top wall 26B and the side wall 26A at both ends in the extension direction of the protective wall 26. The reinforcing portion 26C has a surface 26C1 that faces in a direction inclined inward in the width direction with respect to the downward direction, and this surface 26C1 obliquely connects the widthwise inner surface of the side wall 26A and the widthwise inner surface of the top wall 26B.

The reinforcing portion 26C of the protective wall 26 coincides with the position of the middle elastic portion 53 of the third terminal 5 in the front-rear direction, which is the extending direction.
The intermediate elastic portion 43 of the first terminal 4 and the intermediate elastic portion 53 of the third terminal 5 have approximately the same height. The first curved portion 53B of the intermediate elastic portion 53 of the third terminal 5 is located more inward in the width direction than the first curved portion 43A of the intermediate elastic portion 43 of the first terminal 4. The top wall 26B covers the entire first curved portion 43A of the intermediate elastic portion 43 of the first terminal 4 from above, and covers a portion of the first curved portion 53B of the intermediate elastic portion 53 of the third terminal 5 from above.

As shown in FIG. 9, the dimension in the front-rear direction, which is the extension direction of the protective wall 26, is smaller than the dimension between the pair of front-rear portions 22. As a result, the width direction portion 23 is composed of a central portion 23C in which the protective wall 26 is formed, and an outer portion 23S formed lower than the central portion 23C. The height of the outer portion 23S of the width direction portion 23 is the same as the height of the front-rear portion 22.

The positions in the front-rear direction where the third terminal holding portion 25B is formed are both ends in the front-rear direction, which is the extension direction of the protective wall 26. As a result, the through hole serving as the third terminal holding portion 25B is open outward in the front-rear direction at its upper part. In other words, the upper part of the third terminal holding portion 25B is a groove formed in the outer surface of the protective wall 26 in the front-rear direction. However, the press-fit portion 52A of the fixed side held portion 52 of the third terminal 5 fits into the lower part of the third terminal holding portion 25B and does not reach the groove that constitutes the upper part of the third terminal holding portion 25B.

The fixed housing 2 has a first shield holding portion 27 that holds the fixed-side held portion 63 (see FIG. 12) of the first shield 6 .
A plurality of first shield holding portions 27 (four in the figure) are provided. The four first shield holding portions 27 are formed at boundary positions between the width direction portions 23 and the front-rear direction portions 22 of the fixed housing 2. The first shield holding portions 27 have first shield holding grooves 27A into which the fixed-side held portions 63 of the first shield 6 are press-fitted from above. The first shield holding portions 27 are formed to protrude outward in the width direction, and width direction outer side surfaces 27B of the first shield holding portions 27 are located width direction outer than the width direction outer side surfaces of the width direction portions 23.

As shown in FIG. 10, the fixed housing 2 has a second shield holding groove 29 that holds the fixed-side held portion 74 of the second shield 7 (see FIG. 13).
The second shield retaining groove 29 is located on the inner side in the width direction with respect to the first shield retaining groove 27 A. The second shield retaining groove 29 opens to the lower side of the fixed housing 2, and the press-fitted portion 74A of the fixed-side held portion 74 of the second shield 7 is press-fitted from below.

<Movable housing 3>
FIG. 11 is a perspective view of the movable housing 3. FIG.

The movable housing 3, excluding the protruding guide parts 35, the front and rear protruding parts 36, the arrangement recesses 37, and the storage recesses 39 described below, is sometimes referred to as the main body part 3A. Therefore, it can be said that the movable housing 3 is composed of the main body part 3A, a pair of front and rear protruding guide parts 35, a pair of front and rear protruding parts 36, a pair of widthwise arrangement recesses 37, and four storage recesses 39.

The main body 3A is substantially rectangular and has a pair of front-rear outer side surfaces 3A1 whose normal direction faces outward in the front-rear direction, and a pair of widthwise outer side surfaces 3A2 whose normal direction faces outward in the width direction. The main body 3A also has four connection surfaces 3A3 that diagonally connect the front-rear outer side surfaces 3A1 and the widthwise outer side surfaces 3A2. The front-rear outer side surfaces 3A1, the widthwise outer side surfaces 3A2, and the connection surfaces 3A3 each form the same plane over the entire vertical direction of the main body 3A. However, the widthwise outer side surfaces 3A2 and the connection surfaces 3A3 are formed only on the upper part of the main body 3A due to the formation of the arrangement recess 37 and the storage recess 39.

An insertion space 31 into which a part of a mating connector as a connection object is inserted is formed in the main body 3A of the movable housing 3. The insertion space 31 opens upward. By forming the insertion space 31 in the main body 3A, a pair of front-rear walls 32 opposed to each other in the front-rear direction with the insertion space 31 therebetween, and a pair of width walls 33 opposed to each other in the width direction with the insertion space 31 therebetween are formed in the main body 3A.
Hereinafter, the portion of the main body 3A of the movable housing 3 in which the insertion space 31 is formed will be referred to as the cylindrical portion 3U, and the portion in which the insertion space 31 is not formed (in other words, the portion below the bottom surface 31C of the insertion space 31 (see Figure 5)) will be referred to as the bottom portion 3L.

The main body portion 3A of the movable housing 3 has a first terminal arrangement portion 34 in which a part of the first terminal 4 (the movable-side held portion 44, the tip elastic portion 45, and the contact portion 46) is arranged.
The first terminal arrangement portion 34 is composed of a terminal arrangement groove 34B formed on the widthwise inner surface of the widthwise wall 33, and a terminal arrangement hole 34A penetrating in the vertical direction formed in the bottom portion 3L of the movable housing 3. The movable-side held portion 44 of the first terminal 4 is arranged in a press-fitted and held state in the terminal arrangement hole 34A, and the tip elastic portion 45 and contact portion 46 of the first terminal 4 are arranged in the terminal arrangement groove 34B.

The main body portion 3A of the movable housing 3 has a third terminal arrangement groove 38 in which a part of the third terminal 5 (the movable-side held portion 54, the tip elastic portion 55, and the contact portion 56) is arranged.
The third terminal arrangement grooves 38 are grooves formed on the outer surface 3A1 of the main body 3A in the front-rear direction. The third terminal arrangement grooves 38 are formed with the inner side in the front-rear direction as the depth direction and the extension direction in the up-down direction. Two third terminal arrangement grooves 38 are formed on the front side of the movable housing 3 in the front-rear direction and two on the rear side of the movable housing 3 in the front-rear direction.

As shown in FIG. 7, the depth of the third terminal arrangement groove 38 varies depending on the position in the up-down direction, which is the extension direction. Specifically, the third terminal arrangement groove 38 has an upper portion with a shallow groove depth, a lower portion with a deep groove depth, and an intermediate portion between the upper portion and the lower portion. The bottom surface 38A3 (lower bottom surface) at the lower portion of the third terminal arrangement groove 38 is located more inward in the front-to-rear direction of the connector than the bottom surface 38A1 (upper bottom surface) at the upper portion. The bottom surface 38A2 (intermediate bottom surface) at the intermediate portion of the third terminal arrangement groove 38 connects with the upper bottom surface 38A1 and the lower bottom surface 38A3, and slopes inward in the front-to-rear direction of the connector as it extends downward.

The movable side held portion 54 of the third terminal 5 is press-fitted and held in the lower portion of the third terminal arrangement groove 38, and the contact portion 56 of the third terminal 5 is placed in the upper portion of the third terminal arrangement groove 38. The movable side held portion 54 of the third terminal 5 is placed close to the bottom surface 38A3 at the lower portion of the third terminal arrangement groove 38.

The third terminal arrangement groove 38 has a groove width changing portion 38B where the groove width dimension (dimension in the connector width direction) changes. The groove width dimension is smaller in the portion of the third terminal arrangement groove 38 above the groove width changing portion 38B than in the portion below the groove width changing portion 38B. In the portion of the third terminal arrangement groove 38 other than the groove width changing portion 38B, the groove width dimension is constant throughout the vertical direction, which is the extension direction. The groove width changing portion 38B is formed below the position where the contact portion 56 of the third terminal 5 is arranged and above the position where the first extension portion 55A of the tip elastic portion 55 is arranged.

The movable housing 3 has a protruding guide portion 35 that guides the connection with a mating connector.
The protruding guide portion 35 protrudes upward relative to the main body portion 3A. A pair of the protruding guide portions 35 are formed in the front and rear. The protruding guide portions 35 are formed at positions on the front-rear outer side relative to the insertion space 31, and are not formed at positions overlapping with the insertion space 31 in the front-rear direction. On the other hand, the protruding guide portions 35 are formed not only at positions overlapping with the insertion space 31 in the width direction, but also at positions on the width outer side relative to the insertion space 31. The width dimension of the protruding guide portions 35 is the same as the width dimension of the main body portion 3A of the movable housing 3. The protruding guide portions 35 have a top surface 35A facing upward, and an inclined surface 35B connecting the top surface 35A and the side surfaces 3A1, 3A2, and 3A3 of the main body portion 3A. The upper end of the third terminal arrangement groove 38 reaches the protruding guide portions 35.

The movable housing 3 has front and rear protrusions 36 (restricted portions) for restricting the upward movement range of the movable housing 3 .
The front-rear protrusions 36 are formed on a lower end of the movable housing 3. The front-rear protrusions 36 protrude outward in the front-rear direction from a front-rear outer surface 3A1 of the main body 3A of the movable housing 3. The front-rear protrusions 36 are disposed in a recess serving as the restraining recess 24 of the fixed housing 2.
A terminal passing hole 36A penetrating in the vertical direction is formed in the front-rear protrusion 36 at a position corresponding to the third terminal arrangement groove 38. The terminal passing hole 36A is configured to allow the contact portion 56 of the third terminal 5 to pass therethrough when the third terminal 5 is attached to the movable housing 3.

The movable housing 3 has an arrangement recess 37 in which the movable shield part 71 of the second shield 7 is arranged.
The arrangement recess 37 is formed so as to be recessed inward in the width direction with respect to the width direction outer side surface 3A2 of the main body portion 3A of the movable housing 3. The arrangement recess 37 is formed so as to be open upward in part in the front-rear direction and not open upward in other parts. That is, the arrangement recess 37 is open upward at an opening portion 37A formed in part in the front-rear direction. A pair of opening portions 37A are formed spaced apart in the front-rear direction.
On the other hand, the arrangement recess 37 is open downward over its entire length in the front-rear direction.

The movable housing 3 has an accommodating recess 39 in which the intermediate resilient portion 53 of the third terminal 5 is accommodated.
The accommodating recesses 39 are formed so as to be recessed inward in the width direction with respect to the width direction outer side surfaces 3A2 of the main body portion 3A of the movable housing 3. The accommodating recesses 39 are formed on both front-rear direction sides of the pair of width direction outer side surfaces 3A2 of the main body portion 3A. The accommodating recesses 39 are open not only outward in the width direction, but also outward in the front-rear direction and downward.

A shield holding portion 3B1 that holds the second shield 7 is formed above the accommodation recess 39. A holding groove that opens to the bottom is formed in the shield holding portion 3B1, and the movable held portion 72 of the second shield 7 is pressed into this holding groove from below.

<First Shield 6>
FIG. 12 is a perspective view of the first shield 6. As shown in FIG.

The first shield 6 is manufactured by punching and bending a plate material. The first shield 6 is held in the fixed housing 2 by being pressed into the fixed housing 2 from above (see FIG. 3).

The first shield 6 integrally comprises fixed side shield parts 61, 62 that cover the fixed housing 2, multiple (four in the figure) fixed side held parts 63 that are held by the fixed housing 2, and multiple (four in the figure) board connection parts 64 that extend from each fixed side held part 63.

The fixed side shield parts 61, 62 have a pair of widthwise parts 61 that cover a pair of widthwise parts 23 of the fixed housing 2, and a pair of front-rear parts 62 that cover a pair of front-rear parts 22 of the fixed housing 2.

The width direction portion 61 of the fixed side shield parts 61, 62 has a side portion 61A that covers the width direction portion 23 of the fixed housing 2 from the width direction outer side, a top surface portion 61B that extends inward in the width direction from the upper end of the side portion 61A and covers the protective wall 26 of the fixed housing 2 from above, and a front-rear surface portion 61C that extends inward in the width direction from the upper part of the front end of the side portion 61A and covers the protective wall 26 from the front-rear direction outer side. The width direction inner end of the top surface portion 61B is located widthwise outer than the width direction inner end of the top wall 26B of the protective wall 26 so that the first shield 6 does not abut against the second shield 7.

In addition, the width direction portion 61 of the fixed side shield parts 61, 62 has a first tail covering portion 61D that covers the board fixing portion 41 of the first terminal 4, and a pair of front and rear third tail covering portions 61E that cover the board fixing portion 51 of the third terminal 5.

The first tail covering portion 61D extends from the lower end of the side portion 61A. The first tail covering portion 61D extends diagonally outward and downward in the width direction from the lower end of the side portion 61A in the front-to-rear region where the multiple first terminals 4 are arranged. The tip of the first tail covering portion 61D is located outward in the width direction from the board fixing portions 41 of the multiple first terminals 4. The board fixing portions 41 of the first terminals 4 protrude outward (outward in the width direction) from the outer width direction surface of the width direction portion 23 of the fixed housing 2.

The third tail covering portion 61E is formed near the outer side in the front-rear direction relative to the first tail covering portion 61D. The third tail covering portion 61E extends from the lower end of the side portion 61A. The third tail covering portion 61E is formed in a front-rear direction region in which the board fixing portion 51 of the third terminal 5 is disposed. The board fixing portion 51 of the third terminal 5 protrudes outward (outward in the width direction) beyond the widthwise outer side surface of the widthwise portion 23 of the fixed housing 2.
The third tail covering portion 61E is used as a connecting portion to the carrier when the first shield 6 is manufactured by progressive press working.

The front-rear direction portion 62 of the fixed side shield parts 61, 62 has a side surface portion 62A that covers the front-rear direction portion 22 of the fixed housing 2 from the outside in the front-rear direction, and a top surface portion 62B that extends inward in the front-rear direction from the upper end of the side surface portion 62A and covers the front-rear direction portion 22 of the fixed housing 2 from above. The side surface portion 62A protrudes outward in the width direction beyond the top surface portion 62B, and the widthwise outer end of the side surface portion 62A is located outward in the width direction beyond the fixed side held portion 63.

The fixed side held portion 63 is formed further outward in the front-rear direction than the pair of widthwise portions 61. Each fixed side held portion 63 is flat with its plate thickness oriented in the width direction, and is press-fitted from above into the first shield holding portion 27 formed on the fixed housing 2. Each fixed side held portion 63 has press-fit protrusions on both sides in the front-rear direction, which is the plate width direction. The second side contact portion 76 of the second shield 7 contacts the inner surface of the fixed side held portion 63 (the surface on the inner side in the connector width direction) from the inside in the width direction.

The board connection portion 64 extends outward in the width direction from below the fixed-side held portion 63, with the plate thickness direction facing the up-down direction. The board connection portion 64 is fixed to the board by soldering or the like. As shown in FIG. 4, the outer end of the board connection portion 64 in the width direction is located widthwise outward of the outer side surface of the side portion 61A of the width direction portion 61 and widthwise inward of the outer end of the first tail covering portion 61D in the width direction.

The first shield 6 has a connecting portion 65 that connects the fixed-side held portion 63 and the front-rear direction portion 62. The connecting portion 65 is arc-shaped when viewed in the front-rear direction, and connects the upper end of each fixed-side held portion 63 to the outer end in the width direction of the top surface portion 62B of the front-rear direction portion 62.

The first shield 6 has a connecting portion 66 that connects the fixed side held portion 63 and the width direction portion 61. The connecting portion 66 extends from the upper portion of the inner end portion in the front-rear direction of each fixed side held portion 63. The connecting portion 66 is crank-shaped in a plan view (up-down view), and specifically, it extends outward in the width direction from the fixed side held portion 63 and then bends inward in the front-rear direction. The connecting portion 66 connects the upper portion of the inner end portion in the front-rear direction of the fixed side held portion 63 and the outer end portion in the front-rear direction of the side portion 61A of the width direction portion 61. As a result, the fixed side held portion 63 is located inward in the width direction from the side portion 61A of the width direction portion 61.

The pair of widthwise portions 61 and the pair of front-rearward portions 62 of the fixed side shield parts 61, 62 are connected via four fixed side retained parts 63.

<Second Shield 7>
FIG. 13 is a perspective view of a pair of second shields 7. As shown in FIG.

The second shield 7 is manufactured by punching and bending a plate material. The second shield 7 is held in the movable housing 3 by being pressed into the movable housing 3 from below (see FIG. 3).

The pair of second shields 7 are identical in shape and are positioned facing opposite directions in the width direction.

Each second shield 7 integrally comprises a movable side shield part 71 that covers the movable housing 3, a pair of front and rear movable side held parts 72 held by the movable housing 3, a pair of front and rear shield spring parts 73 extending from the front and rear movable side held parts 72, a pair of front and rear fixed side held parts 74 formed on the tip side of the front and rear shield spring parts 73 and held by the fixed housing 2, a pair of front and rear elastic support parts 75 extending from the front and rear fixed side held parts 74, and a second side contact part 76 supported by the elastic support parts 75.

The movable shield part 71 is a flat plate with its thickness oriented in the width direction. The movable shield part 71 is disposed in the recessed arrangement part 37 of the movable housing 3 and covers the movable housing 3 from the outside in the width direction. The lower end of the movable shield part 71 is located below the upper end of the protective wall 26 of the fixed housing 2 (see FIG. 5).

The movable shield part 71 has a tip extension part 71A, the upper end of which is partially extended upward. A pair of tip extension parts 71A are formed at the front and rear. The tip extension parts 71A are arranged in the open part 37A of the arrangement recess 37 of the movable housing 3.

The front and rear movable-side held parts 72 are connected to the movable-side shield part 71 via a pair of front and rear inclined connecting parts 77. The front and rear inclined connecting parts 77 extend diagonally from the movable-side held part 72 side toward the outside in the front-rear direction and toward the inside in the width direction. The front and rear inclined connecting parts 77 connect the lower parts of both front-rear direction ends of the movable-side shield part 71 to the lower parts of the front and rear movable-side held parts 72.

The movable-side held portion 72 has a press-fit portion 72A extending upward, and the press-fit portion 72A is press-fit from below into the front and rear shield holding portions 3B1 of the movable housing 3. Each press-fit portion 72A has a locking protrusion formed only on the inner side in the front-to-rear direction, and no locking protrusion is formed on the outer side in the front-to-rear direction.

The front and rear shield spring parts 73 extend downward, then extend outward and upward in the width direction, and then extend downward again, forming an S-shape when viewed in the front-rear direction. That is, the shield spring part 73 has a first downward extension part 73A, an upward extension part 73B, and a second downward extension part 73C. The first downward extension part 73A extends downward from the lower end of the movable-side held part 72. The lower end of the first downward extension part 73A is located near the top of the board (a position that overlaps with the front and rear protrusions 36 of the movable housing 3 in the up-down direction). The upward extension part 73B extends diagonally upward and outward in the width direction. The second downward extension part 73C extends downward. The shield spring part 73 is formed by bending in the plate thickness direction.

The fixed side held portion 74 extends outward in the front-to-rear direction from the end of the shield spring portion 73, and then extends upward. The fixed side held portion 74 has a press-fit portion 74A, which is pressed into the second shield holding groove 29 formed at both front and rear ends of the fixed housing 2 from below. The press-fit portion 74A is located outward in the front-to-rear direction from the shield spring portion 73. The press-fit portion 74A has locking protrusions formed on both sides in the front-to-rear direction, which is the plate width direction.

The elastic support portion 75 extends outward and downward in the width direction from the upper end of the fixed-side held portion 74 (the upper end of the press-fit portion 74A). The second-side contact portion 76 is formed on the tip side of the elastic support portion 75 and elastically contacts the fixed-side held portion 63 of the first shield 6 from the inside in the connector width direction (see FIG. 6). This electrically connects the second shield 7 and the first shield 6.

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

In this embodiment, the connector 1 includes a first terminal 4 and housings 2 and 3. The housings 2 and 3 include a fixed housing 2 whose position is fixed with respect to an object to which the connector is to be attached (such as a board), and a movable housing 3 that is movable with respect to the fixed housing 2.
Furthermore, the connector 1 includes shields 6 and 7. The shields 6 and 7 each have a ground portion (board connection portion 64) that is connected to an attachment object (such as a board), and a movable-side shield portion 71 that is electrically connected to the ground portion (board connection portion 64) and is attached to the movable housing 3. Therefore, grounding is performed at the ground portion (board connection portion 64), and the movable housing 3 is shielded by the movable-side shield portion 71 that is electrically connected to the ground portion (board connection portion 64).
Furthermore, the shields 6, 7 have a deformable shield spring portion 73 that is located between the ground portion (board connection portion 64) and the movable shield portion 71. Therefore, the deformation of the shield spring portion 73 allows the movable shield portion 71 to move relative to the ground portion (board connection portion 64). As a result, in the connector 1 that includes the movable housing 3, the movable housing 3 can be appropriately shielded.
In the above embodiment, the shields 6, 7 are configured to include the first shield 6 and the second shield 7 that are separate from each other, but the effects of this configuration are not limited to this. The shield may have a ground portion (substrate connection portion 64) and the movable shield part 71 integrally.

In addition, in this embodiment, the shields 6 and 7 have fixed shield parts 61 and 62 that are attached to the fixed housing 2. Therefore, noise countermeasures can be improved compared to an embodiment in which the shields 6 and 7 do not have the fixed shield parts 61 and 62.

However, it can be difficult to manufacture a complex shield that covers a wide area from a single metal plate.
Therefore, in this embodiment, the shields 6, 7 include a first shield 6 and a second shield 7 that is separate from the first shield 6. The first shield 6 has fixed shield parts 61, 62, and the second shield 7 has a movable shield part 71.
For this reason, the movable shield part 71 attached to the movable housing 3 and the fixed shield parts 61, 62 attached to the fixed housing 2 are formed as the first shield 6 and the second shield 7, which are separate from each other. This makes it easy to form a shield that covers a complex and wide area.

13 , the second shield 7 has a shield spring portion 73 and a second-side contact portion 76 that comes into contact with the first shield 6. The shield spring portion 73 is located between the movable shield part 71 and the second-side contact portion 76.
For this reason, it is possible to prevent the first shield 6 from becoming complicated, as compared to an embodiment in which the first shield 6 has the shield spring portion 73. When the first shield 6 can be prevented from becoming complicated, the degree of freedom in designing the fixed side shield parts 61, 62 of the first shield 6 is improved.

In this embodiment, the second shield 7 has a fixed-side held portion 74 that is located on the opposite side of the shield spring portion 73 from the movable-side shield portion 71 and is held by the fixed housing 2 .
This prevents the second side contact portion 76 of the second shield 7 from moving together with the movable housing 3, and as a result, sliding between the second side contact portion 76 of the second shield 7 and the first shield 6 is prevented.

In addition, in this embodiment, the fixed side held portion 74 is located between the second side contact portion 76 and the shield spring portion 73 .
This further prevents the second side contact portion 76 of the second shield 7 from moving together with the movable housing 3, and as a result, sliding between the second side contact portion 76 of the second shield 7 and the first shield 6 is further prevented.

In addition, in this embodiment, the second shield 7 has an elastic support portion 75 that elastically supports the second side contact portion 76 with respect to the fixed side held portion 74 .
Therefore, even if a deviation occurs in the position where the fixed side held portion 74 of the second shield 7 is held, the contact state between the second side contact portion 76 and the first shield 6 is less likely to be affected.

In this embodiment, the fixed-side held portion 74 of the second shield 7 is held by being press-fitted from below into the fixed housing 2. The elastic support portion 75 extends obliquely downward from above the fixed-side held portion 74.
Therefore, compared to a configuration in which the elastic support portion 75 extends obliquely upward from above the fixed-side held portion 74, it is easier to ensure the vertical dimension of the fixed-side held portion 74.

In this embodiment, the first shield 6 has a first side contact portion 63 that contacts the second side contact portion 76 of the second shield 7. The first side contact portion 63 has an outer surface facing the outside of the connector and an inner surface facing the inside of the connector. The second side contact portion 76 contacts the inner surface of the first side contact portion 63.
As a result, the second side contact portion 76 is less likely to be exposed to the outside of the connector, and damage to the second side contact portion 76 is suppressed.

In the present embodiment, the first shield 6 has a fixed-side held portion 63 that is held by the fixed housing 2. The fixed-side held portion 63 of the first shield 6 also serves as the first-side contact portion 63 that comes into contact with the second-side contact portion 76 of the second shield 7.
Therefore, the position of the first side contact portion (the fixed side held portion 63) is less likely to shift, and the contact state between the first shield 6 and the second shield 7 is stable.

Next, the effects of this embodiment will be explained from another perspective.

In this embodiment, the connector 1 includes housings 2 and 3. The housings 2 and 3 each have a cylindrical portion 3U in which an insertion space 31 is formed, into which a connection object (such as a part of a mating connector) is inserted from above.
The connector 1 also includes shields 6 and 7. The shields 6 and 7 each have a main body portion (movable shield portion 71) that covers the tubular portion 3U from the outside in the width direction, and a pair of front and rear held portions (movable held portions 72) that are held by the housings 2 and 3.
Here, the positions at which the pair of front and rear held portions (movable held portions 72) are held are on the front-rear outer side of the insertion space 31. For this reason, the shields 6, 7 can be held in the portion of the cylindrical portion 3U that has a larger width dimension, so that the shields 6, 7 can be easily and reliably held.
In the above embodiment, the housings 2, 3 include the fixed housing 2 and the movable housing 3, and the shields 6, 7 include the first shield 6 and the second shield 7. However, the effect is not limited to this configuration. The connector does not have to be a floating connector.

In addition, in this embodiment, the pair of front and rear held parts (movable held parts 72) are located widthwise inward of the main body part 3A. This allows the position at which the movable held parts 72 are held in the housing (movable housing 3) to be shifted widthwise inward. This allows the shield (second shield 7) to be properly held in the housing while keeping the width dimension of the housing (movable housing 3) small.

11, the housing (movable housing 3) has a pair of front and rear holding parts (shield holding parts 3B1) that hold the pair of front and rear held parts (movable held parts 72), and a pair of front and rear lower recesses (accommodating recesses 39) that are formed below the pair of front and rear holding parts (shield holding parts 3B1) and are recessed inward in the width direction. The pair of front and rear held parts (movable held parts 72) of the shields 6, 7 are press-fitted from below into the pair of front and rear holding parts (shield holding parts 3B1) of the housing (see FIGS. 2 and 3).
Therefore, unlike the embodiment in which the press-fit direction of the held portion into the housing is inward in the width direction, the inner width portion of the front-to-rear portion of the housing (the portion outer in the front-to-rear direction than the insertion space 31) can be easily used for other purposes (e.g., holding the third terminal 5).

In addition, in this embodiment, the housings 2 and 3 have a recessed arrangement 37 in which the outer surface 3A2 of the housings 2 and 3 in the width direction is recessed inward in the width direction and in which the main body portion (movable shield portion 71) of the shields 6 and 7 is arranged. This allows for a smaller size in the width direction.

In addition, in this embodiment, the housings 2 and 3 have a peeling prevention portion 3C that is disposed above the upper end of the main body portion 3A (see FIG. 1). This prevents the shield from peeling off when connecting to a connection object, etc.

In addition, in this embodiment, the main body (movable shield part 71) has a tip extension part 71A in which the upper end of the main body (movable shield part 71) is partially extended upward. This allows the effective mating length with the mating connector to be increased.

In addition, in this embodiment, the peeling prevention portion 3C is not formed at a position corresponding to the tip extension portion 71A of the main body portion 3A. Therefore, the tip extension portion 71A can be extended upward a long distance, making it easier to ensure the effective engagement length.

[Supplementary explanation of the above embodiment]
In the above embodiment, an example has been described in which the movable shield part 71 arranged on one side in the width direction and the movable shield part 71 arranged on the other side in the width direction are provided on a pair of second shields 7 that are separate bodies, but the present disclosure is not limited to this. The second shield 7 may be formed integrally.

In the above embodiment, an example in which the connector 1 is a socket has been described, but the present disclosure is not limited to this. The connector may be a plug.

In addition, in the above embodiment, an example was described in which the fixed housing 2 is frame-shaped, but the present disclosure is not limited to this.
