Connector assembly, receptacle type connector, and interface apparatus

A receptacle type connector able to receive either a coaxial cable plug type connector to which a coaxial cable is connected or a single-wire plug type connector to which a plurality of single wires are connected, wherein

• the receptacle type connector comprises:
• a first group of contacts, for electrical connection with the coaxial cable plug type connector, including a first signal contact and a pair of ground contacts positioned symmetrically about the first signal contact;
• a second group of contacts, for electrical connection with the single-wire plug type connector, including the first signal contact and a pair of second signal contacts positioned at two points which are in an equal distance from the first signal contact;
• and
• an insulative housing for holding the first group of contacts and the second group of contacts.
