However, a shield plate of a type grounded to a substrate and a shield plate of a type to be brought into contact with an external shield member of a housing are completely different from each other. For this reason, the type which takes each shield and a housing are also different, and another connector is manufactured by the way of taking a shield. In other words, when producing in each, equipment for each type was required separately.

[0005] Therefore, the shield plate requires a portion to be brought into contact with the connector and shielded for each connector in the board or the external shield member, which is inferior in economy.

It is therefore an object of the present invention to provide a connector having a shield plate that can share a shield plate.

[0007]

According to the present invention, in a connector including an insulating housing and a shield plate which comes into contact with a mating shield plate provided on a mating connector fitted to the housing, the shield plate is provided with: The shield plates provided on each of the plurality of housings arranged on the substrate are brought into contact with each other, and the shield plate provided on the outermost housing is brought into contact with an external shield member and / or a shield layer of the substrate. A connector having a shield plate is obtained, wherein the connector has a contact portion that shields the entire surface of the plurality of housings on the substrate.

[0008]

According to the connector having the shield plate of the present invention, the shield plate is used for contacting the shield plates of the housing arranged in the row direction on the board, and for the connector of the housing arranged in the column direction on the board. There are two types of shield plates that come into contact with each other.

The shield plate is used with one or a combination of the shield plates according to the purpose of the shield. That is, both or one of the shield plates is used according to the purpose of the shield.
