PROBLEM TO BE SOLVED: To implement a connection interface for signals to which high-speed and large-capacity performance is required in connector connection.SOLUTION: A first connector device and a second connector device which can be mounted to the first connector device are provided. The first and second connector devices are mounted to each other to form an electromagnetic field coupling unit. A transmission target signal is converted to a radio signal, and then the radio signal is transmitted through the electromagnetic field coupling unit. For example, radio transmission is performed through an electromagnetic field coupling unit 12 while the first connector device serves as a receptacle 22 and the second connector device serves as a plug 42. Radio transmission is performed through an electromagnetic field coupling unit 14 while the first connector device serves as a receptacle 84 and the second connector device serves as a plug 44. Connector connection for signals is implemented by radio transmission using electromagnetic field coupling. Therefore, high-frequency restriction caused by the shape and arrangement of connector electrodes designed for an earlier generation interface can be removed, and a signal shaping technique is not necessarily required.

An electromagnetic field coupling part is formed by mounting the first connector device and the second connector device, a transmission target signal is converted into a radio signal, and the radio signal is then transmitted via the electromagnetic field coupling part. For example, the first connector device is used as a receptacle 22 and the second connector device is used as a plug 42 to perform radio transmission via an electromagnetic field coupling part 12. The first connector device is used as a receptacle 84 and the second connector device is used as a plug 44 to perform radio transmission via an electromagnetic field coupling part 14. By implementing signal connector connection through radio transmission utilizing electromagnetic field coupling, the connector connection is prevented from being limited by high frequency limitations according to a shape and an arrangement of a connector electrode designed for a former-generation interface and application of signal shaping techniques is not always required, either.
