Abstract
PURPOSE:To prevent an excess current from flowing when a 2nd input terminal is fallen into a short-circuit state, by interpositing a positive characteristic thermister to a connecting circuit between an output terminal and the 2nd input terminal connecting a television receiver antenna. CONSTITUTION:The positive characteristic thermister 31 provided to a connecting circuit 30 keeps passing of a current to a power application equipment normally and its own resistance is increased when an excess current due to short-circuiting flows to the circuit 30 to control the current from the output terminal 28 to the 2nd input terminal 27 to a small value. In connecting a television reception antenna 5 using no power to the 2nd input terminal 27 of a mixer 3, the terminal 27 of the mixer 3 is short-circuited to the power for operating the device via an internal circuit of the antenna 5. Since the positive characteristic thermister 31 is interposed to the connection circuit 30 of the mixer 30, the current for device operation power flowing to the connection circuit 30 is limited to a small value.
