Patent ID: 7611383

Claim:
An RJ45 connector device having a key structure for changing pin definitions, comprising: a base, having a recess and an accommodation space, wherein a hole is disposed at a position where the recess and the accommodation space are separated from each other; a conversion circuit board, disposed in the accommodation space, wherein a conversion processor is disposed on the conversion circuit board; a set of input pins, disposed within the recess and electrically connected to the conversion circuit board; a key circuit board, disposed in the accommodation space, wherein a key is disposed on the key circuit board corresponding to the hole, and the key circuit board is electrically connected to the conversion circuit board; an information processing circuit board, electrically connected to the conversion circuit board and comprising an information processor; and an output circuit board, electrically connected to the information processing circuit board and comprising a set of output pins; wherein when the key is pressed, a conversion signal is triggered; the conversion processor converts a part of input information input by a designated input pin in the set of input pins into relay information and transfers the relay information, the conversion signal, and the input information into the information processor; and then the information processor converts the input information and the relay information into output information through designated processing according to the conversion signal, and transfers the output information to be output via the set of output pins.
