As described above, in the conventional electronic equipment having the lid for opening the internal connector from the outside in the opening, the lid is used when connecting the connector of another electronic equipment. Because it has to be removed from the opening,
Connection work was complicated. Also, if the connectors are connected when the electronic devices are fitted together,
There is also a problem that the electronic devices are fitted together by forgetting to remove the lid from the opening, and the connectors are not connected to each other.

The present invention has been made to solve the above-mentioned conventional drawbacks. When the external connector is detached from the internal connector, the opening of the housing is closed and the external connector is closed. An object of the present invention is to provide an electronic device in which an opening is automatically opened when an external connector is inserted into the opening so as to connect the connector to the internal connector.

[0007]

According to the present invention, an opening is formed in a housing, and a connector to which an external connector inserted from the outside of the housing is connected is provided with the opening in the housing. In an electronic device provided to face each other, a base end side is attached in the vicinity of the opening of the housing, and a lid formed on the tip end side is positioned so as to close the opening. A shutter provided with elasticity is provided in the housing in the middle part between the lid and the lid so that the lid can be moved in a direction of opening the opening by the pressing force of the external connector inserted into the opening. It has been configured.

[0008]

According to the present invention, when the external connector is inserted into the opening of the housing to connect it to the connector inside the housing, the lid of the shutter, which is pressed by the external connector, opens the opening due to the elastic force of the middle portion. When the external connector is pulled out from the opening, it returns to the original position of closing the opening due to the elastic force in the middle.
