The present invention relates to a connector for mounting a printed circuit board or the like for electrically connecting a plurality of substrates.

Conventionally, such a connector has a first housing that is disposed on one side of the connection object, and a second housing that is disposed on the other side of the connection object and that can be fitted to the first housing. a plurality of first terminals held by the first housing; a first shielding member formed on the first housing and extending in an arrangement direction of the first terminals; being held by the second housing, in the second When the housing is fitted into the first housing, respectively contacting a plurality of second terminals formed by the first terminals; and a second portion formed in the second housing and extending in the direction in which the second terminals are arranged A shield member (see, for example, Japanese Patent Laid-Open Publication No. 2002-298983).

In the connector, EMI (Electro Magnetic Interference) countermeasures for each case are performed by providing shield members in the first and second cases, respectively.

However, when the connector is fitted to the first housing in the second housing, the second shielding member is formed to be coupled to the specific position of the first shielding member, and therefore, the second housing is fitted to the first housing. In the state of the body, the second casing cannot be moved, and when a positional deviation occurs between one of the connection objects and the other connection object, the positional deviation may not be absorbed.

The present invention has been made in view of the above problems, and an object thereof is to provide a connector that can perform EMI countermeasures for the first and second housings and that can move the second housing to the first housing.

When the second housing is fitted to the first housing, it contacts the first and second shielding members and is elastically deformed accompanying the movement of the second housing.

Thereby, since the specific outer peripheral surface of the first casing is covered by the first shield member, and the specific outer peripheral surface of the second casing is covered by the second shield member, countermeasures against EMI can be performed. Further, since the first terminal is elastically deformed in contact with the second terminal, and the shield conductive portion is elastically deformed in contact with the first and second shield members, the movement of the second housing is allowed. Therefore, according to the present invention, the movement of the second casing to the first casing can be performed. Therefore, when a positional deviation occurs between one of the connection object and the other connection object, the positional deviation can be absorbed. Improve connection reliability. Further, since the present invention can perform the EMI countermeasures for the first and second casings, the influence of the electromagnetic waves can be surely reduced.
