The system operation at the time of connection or disconnection of the connector for a railway vehicle having the above-mentioned configuration is such that, at the time of the middle connection of the railway car, the air pipe is connected at the same time as the mechanical close- It must be connected. At this time, the connection speed of the railway vehicle is 2 km / h or less.

However, the conventional connector for a railway vehicle has a problem that when the connector is connected / disconnected, the close connector and the electric connector are connected / disconnected at the same time.

In this case, although the conventional connector for a railway vehicle maintains the disconnected connector in the disconnected state, since the electrical connection is made during the electrical connection, all of the vehicles may move without being disconnected when the vehicle is disconnected.

Also, when connecting / disconnecting in a curved line, the close connector maintains the connection / disconnection state, but the electrical connector may not be connected.

As a result, the electrical connector breaks or the pins inside the electrical connector break.

Therefore, it is required to develop a connector for an improved railway vehicle in which an electric connector is connected to the railway vehicle after the close connection, and an electric connector is separated from the close connector when the railway car is separated.
