PURPOSE: An outer antenna interface device of a hands-free kit is provided to form a contact hole in an antenna holder, and to install a connection terminal in a hands-free kit, in order to connect an outer antenna with a mobile communication terminal without using an RF connector, thereby freely designing a PCB substrate. CONSTITUTION: A contact hole(2a) pierces through an antenna holder(2) of a mobile communication terminal(1). An RF adapter(5) is inserted into the contact hole(2a) in a predetermined part of a hands-free kit where the mobile communication terminal(1) is put, and is connected with an antenna of the mobile communication terminal(1). The RF adapter(5) comprises as follows. A connection pin(11) is inserted into the contact hole(2a) of the antenna holder(2). A spring(12) is used such that the connection pin(11) can be inserted into the contact hole(2a) in buffer way.
