<Effect>
Next, the effects of this embodiment will be explained.

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 be attached (such as a board), and a movable housing 3 which is movable with respect to the fixed housing 2.
Furthermore, the connector 1 includes shields 6 and 7. The shields 6 and 7 are attached to the movable housing 3 while being electrically connected to a grounding part (board connection part 64) connected to an object to be attached (board etc.) and a grounding part (board connection part 64). It has a movable side shield part 71. Therefore, the movable housing 3 is grounded at the grounding portion (board connecting portion 64), and the movable housing 3 is shielded by the movable side shield portion 71 that is electrically connected to the grounding portion (board connecting portion 64).
Furthermore, the shields 6 and 7 have a deformable shield spring part 73 located between the grounding part (board connection part 64) and the movable shield part 71. Therefore, by deforming the shield spring portion 73, movement of the movable shield portion 71 with respect to the grounding portion (board connection portion 64) is permitted. As a result, in the connector 1 including the movable housing 3, the movable housing 3 can be appropriately shielded.
In addition, although the said embodiment demonstrated the structure in which the shields 6 and 7 are provided with the 1st shield 6 and the 2nd shield 7 which were mutually separate bodies, this effect is not limited to the said structure. The shield may integrally include a grounding portion (board connection portion 64) and a movable shield portion 71.

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

However, it may be difficult to manufacture a complex shield that covers a wide area from a single metal plate.
Therefore, in this embodiment, the shields 6 and 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 side shield parts 61 and 62, and the second shield 7 has a movable side shield part 71.
Therefore, the movable side shield part 71 attached to the movable housing 3 and the fixed side shield parts 61 and 62 attached to the fixed housing 2 are attached to the first shield 6 and the second shield 7, which are separate bodies, respectively. It is formed. Therefore, it is easy to create a shield that is complex and covers a wide range.

Further, in this embodiment, as shown in FIG. 13, the second shield 7 includes a shield spring portion 73 and a second side contact portion 76 that contacts the first shield 6. The shield spring portion 73 is located between the movable side shield portion 71 and the second side contact portion 76.
Therefore, compared to the embodiment in which the first shield 6 includes the shield spring portion 73, the first shield 6 can be prevented from becoming complicated. If the complexity of the first shield 6 can be suppressed, the degree of freedom in designing the fixed side shield parts 61 and 62 of the first shield 6 will be improved.

Further, in the present embodiment, the second shield 7 includes a fixed side held portion 74 that is located on the opposite side of the movable side shield portion 71 with respect to the shield spring portion 73 and is held by the fixed housing 2 .
Therefore, the second side contact portion 76 of the second shield 7 is prevented from moving together with the movable housing 3, and as a result, the second side contact portion 76 of the second shield 7 and the first shield 6 are prevented from sliding. suppressed.

Further, in this embodiment, the fixed side held part 74 is located between the second side contact part 76 and the shield spring part 73.
Therefore, the movement of the second side contact portion 76 of the second shield 7 together with the movable housing 3 is further suppressed, and as a result, the sliding movement between the second side contact portion 76 of the second shield 7 and the first shield 6 is suppressed. is further suppressed.

Further, in this embodiment, the second shield 7 includes 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 shift occurs in the position at which 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 hardly affected.

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

Further, 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. Then, the second side contact portion 76 contacts the inner surface of the first side contact portion 63.
Therefore, 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.

Further, in this embodiment, the first shield 6 includes 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 contacts the second side contact portion 76 of the second shield 7 .
Therefore, the position of the first side contact portion (fixed side held portion 63) is unlikely to shift, and the contact state between the first shield 6 and the second shield 7 is stabilized.

Next, the effects of this embodiment will be explained from other viewpoints.

In this embodiment, the connector 1 includes housings 2 and 3. The housings 2 and 3 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 include a main body portion (movable side shield portion 71) that covers the cylindrical portion 3U from the outside in the width direction, and a pair of front and rear held portions (movable side held portions 72) held by the housings 2 and 3. , has.
Here, the position where the pair of front and rear held parts (movable side held part 72) is held is outside the insertion space 31 in the front and back direction. For this reason, the shields 6 and 7 can be held in the portions of the cylindrical portion 3U that are large in width direction, making it easy to securely hold the shields 6 and 7.
In the above embodiment, an example has been described in which the housings 2 and 3 include the fixed housing 2 and the movable housing 3, and the shields 6 and 7 include the first shield 6 and the second shield 7. is not limited to this configuration. The connector does not have to be a floating connector.

Further, in the present embodiment, the pair of front and rear held parts (movable side held part 72) are located on the inner side in the width direction than the main body part 3A. Therefore, the position where the movable side held portion 72 is held in the housing (movable housing 3) can be moved inward in the width direction. Therefore, the shield (second shield 7) can be appropriately held in the housing while suppressing the width dimension of the housing (movable housing 3).

In this embodiment, as shown in FIG. 11, the housing (movable housing 3) includes a pair of front and rear holding parts (shield holding part 3B1) that hold a pair of front and rear held parts (movable side held part 72). and a pair of front and rear lower recesses (accommodating recesses 39) formed below the front and rear pair of holding parts (shield holding part 3B1) and recessed inward in the width direction. The pair of front and rear held parts (movable side held part 72) of the shields 6 and 7 are press-fitted from below into the pair of front and rear holding parts (shield holding part 3B1) of the housing (Fig. (See 3).
Therefore, unlike the mode in which the press-fitting direction of the held part into the housing is the inner side in the width direction, the inner part in the width direction of the front-rear part of the housing (the part outside the insertion space 31 in the front-rear direction) is used for other purposes ( For example, it can be easily used for holding the third terminal 5, etc.).

In addition, in the present embodiment, the housings 2 and 3 have their outer surfaces 3A2 in the width direction recessed toward the inner side in the width direction, and the main bodies (movable shield portions 71) of the shields 6 and 7 are disposed. It has a placement recess 37. Therefore, it is possible to reduce the size in the width direction.
