Patent ID: 8308507

Claim:
A KVM cable with video connectors, PS/2 connectors and USB connector, comprising: a first video connector, being used for connecting to a video connection port of a KVM device; a second video connector, being used for connecting to a video connection port of a computer; a main cable, being connected with the first video connector and the second video connector, and adopted for transmitting signals between the first video connector and the second video connector; a first branch cable, one terminal thereof extending from the main cable and being connected with the second video connector; a first PS/2 connector, being connected with the another terminal of the first branch cable, and used for connecting to a first PS/2 connection port of the computer; a second branch cable, one terminal thereof extending from the main cable and being connected with the second video connector; a second PS/2 connector, being connected with the another terminal of the second branch cable and used for connecting to a second PS/2 connection port of the computer; and at least one USB connector, being connected to the second video connector through a third branch cable extending from the main cable and used for connecting to an USB connection port of the computer; wherein by way of the first branch cable, a first un-used pin, a first un-connected pin, a second un-connected pin, and a first ground pin of the first video connector may electrically connect to a first PS/2 data pin, a first PS/2 clock pin, a first PS/2 voltage pin, and a first PS/2 ground pin of the first PS/2 connector, respectively; moreover, by means of the first branch cable, the first video connector and the third branch cable, the first PS/2 data pin, the first PS/2 clock pin, the first PS/2 voltage pin, and the first PS/2 ground pin of the first PS/2 connector can electrically connect to an USB negative data pin, an USB positive data pin, an USB voltage pin, and an USB ground pin of the USB connector, respectively; wherein a diode device is disposed between the first PS/2 voltage pin and the USB voltage pin; in addition, one end of a detecting resistor being coupled to the diode device and the USB voltage pin, and the another end of the detecting resistor being electrically connected to a second ground pin of the first video connector; wherein the data transmitted by the PS/2 connectors and the USB connector is selected from the group consisting of: a keyboard input/output data and a mouse input/output data.
