The shield may have a grounding portion (board connection portion 64) and a movable side shield portion 71 integrally.

Further, in the present embodiment, the shields 6 and 7 have fixed side shield portions 61 and 62 mounted on the fixed housing 2. Therefore, noise countermeasures can be improved as compared with the mode in which the shields 6 and 7 do not have the fixed side shield portions 61 and 62.

By the way, it may be difficult to manufacture a shield covering a complicated and wide range from a single metal plate.
Therefore, in the present 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 portions 61 and 62, and the second shield 7 has movable-side shield portions 71.
Therefore, the movable side shield portion 71 mounted on the movable housing 3 and the fixed side shield portions 61 and 62 mounted on the fixed housing 2 are separated from each other on the first shield 6 and the second shield 7, respectively. It is formed. Therefore, it is easy to make a shield that covers a complicated and wide range.

Further, in the present embodiment, as shown in FIG. 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 side shield portion 71 and the second side contact portion 76.
Therefore, the complexity of the first shield 6 can be suppressed as compared with the embodiment in which the first shield 6 has the shield spring portion 73. If the complexity of the first shield 6 can be suppressed, the degree of freedom in designing the fixed-side shield portions 61 and 62 of the first shield 6 is improved.

Further, in the present embodiment, the second shield 7 has a fixed-side held portion 74 that is located on the side opposite to 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 suppressed 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 slide. It is suppressed.

Further, in the present embodiment, the fixed side held portion 74 is located between the second side contact portion 76 and the shield spring portion 73.
Therefore, the second side contact portion 76 of the second shield 7 is further suppressed 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 slide. Is further suppressed.

Further, in the present 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 the position where the fixed side held portion 74 of the second shield 7 is held is displaced, the contact state between the second side contact portion 76 and the first shield 6 is not easily affected.

Further, in the present embodiment, the fixed side held portion 74 of the second shield 7 is held by being press-fitted into the fixed housing 2 from the lower side. The elastic support portion 75 extends obliquely downward from above the fixed-side held portion 74.
Therefore, it is easy to secure the vertical dimension of the fixed-side held portion 74 as compared with the embodiment in which the elastic support portion 75 extends obliquely upward from above the fixed-side held portion 74.

Further, in the present embodiment, the first shield 6 has a first side contact portion 63 that comes into contact with 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 comes into contact with 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 the present embodiment, the first shield 6 has a fixed side held portion 63 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 (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 action and effect of this embodiment will be described from another viewpoint.

In this embodiment, the connector 1 includes housings 2 and 3. The housings 2 and 3 have a tubular portion 3U in which an insertion space 31 into which an object to be connected (a part of a mating connector or the like) is inserted is formed from above.

The shields 6 and 7 include a main body portion (movable side 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 side held portion 72) that are held by the housings 2 and 3. , Have.
Here, the position where the pair of front and rear held portions (movable side held portions 72) is held is outside the insertion space 31 in the front-rear direction. Therefore, the shields 6 and 7 can be held in the portion of the tubular portion 3U having a large width direction, so that the shields 6 and 7 can be held securely.
In the above embodiment, the configuration 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 has been described. 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 portions (movable side held portions 72) are located inside the main body portion 3A in the width direction. Therefore, the position of holding the movable side held portion 72 in the housing (movable housing 3) can be moved inward in the width direction. Therefore, the shield (second shield 7) can be appropriately held by the housing while suppressing the width dimension of the housing (movable housing 3).

Further, in the present embodiment, as shown in FIG. 11, the housing (movable housing 3) has a pair of front and rear holding portions (shield holding portion 3B1) that hold a pair of front and rear held portions (movable side held portions 72). And a pair of front and rear lower recesses (accommodation recesses 39) formed below the pair of front and rear holding portions (shield holding portion 3B1) and recessed inward in the width direction. Then, the pair of front and rear held portions (movable side held portions 72) of the shields 6 and 7 are press-fitted into the pair of front and rear holding portions (shield holding portions 3B1) of the housing from below (FIGS. 2 and 2). 3).
Therefore, unlike the embodiment in which the press-fitting direction of the held portion with respect to the housing is inside in the width direction, the portion inside the width direction in the portion in the front-rear direction of the housing (the portion outside in the front-rear direction from the insertion space 31) is used for other purposes ( For example, it is easy to use for holding the third terminal 5.

Further, in the present embodiment, in the housings 2 and 3, the outer surface 3A2 of the housings 2 and 3 in the width direction is recessed inward in the width direction, and the main body portions (movable side shield portion 71) of the shields 6 and 7 are arranged. It has an arrangement recess 37 to be formed. Therefore, it is possible to reduce the size in the width direction.

Further, in the present embodiment, the housings 2 and 3 have a peeling prevention portion 3C arranged above the upper end of the main body portion 3A (see FIG. 1). Therefore, it is possible to prevent the shield from peeling off when connecting to the object to be connected.

Further, in the present embodiment, the main body portion (movable side shield portion 71) has a tip extension portion 71A in which the upper end of the main body portion (movable side shield portion 71) is partially extended upward. Therefore, the effective mating length with the mating connector can be lengthened.

Further, in the present 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, since the tip extension portion 71A can be extended upward for a long time, it is easy to secure an effective fitting length.

[Supplementary Description of the above Embodiment]
