摘要： 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.
