PURPOSE: A connector unit is provided to switch an external antenna and an internal antenna to each other only by inserting/separating a plug into/from the connector unit. CONSTITUTION: A connector unit(1) includes a housing, an internal antenna arranged inside the housing, a wireless signal processor for processing a wireless signal, and an external antenna inserted/separated into/from the housing. The connector unit further includes a printed board having the first micro-strip line connected to the wireless signal processor and the second micro-strip line connected to the internal antenna, a fixed contact(12) installed on the printed board and coupled to the second micro-strip line, a moving contact(11) coupled to the second micro-strip line and pressed against the fixed contact, and a socket covering the moving contact and the fixed contact. The external antenna is inserted into the socket such that the front end of the external antenna is interposed between the moving contact and the fixed contact to come into contact with the moving contact and, simultaneously, separates the moving contact from the fixed contact. Then, the external antenna is connected to the wireless signal processor. When the external antenna is separated from the socket, the moving contact comes into contact with the fixed contact and the internal antenna is connected to the wireless signal processor.
