  • Structure and circuit of input/output port bar to connect computer peripheral
    Patent number: 6424522
    Abstract: A structure and a circuit of an input/output (I/O) port bar to connect between a computer and a computer peripheral. The structure of the I/O port bar has a laminate, a loop and a sliding member (with a pushing portion, a first protrusion portion and a second protrusion portion). Thus constructed, the connecting cable can be restored to the inside of the I/O port bar. In the circuit of the I/O port bar, a power switching circuit is formed to control whether the power of the main circuit is supplied by an external computer via the connecting cable or directly by an external DC power source.
