Patent ID: 7353408

Claim:
A USB (Universal Serial Bus) connector device for interconnecting electrically an electronic instrument and an external peripheral device, the USB connector device comprising: a USB interface adapted to be mounted on the electronic instrument, and adapted to supply electrical power to the external peripheral device for data transmission therebetween, said USB interface for supplying a maximum current of 2 amperes wherein, when the required current for operating the external peripheral device exceeds the amount of 2 amperes, said USB interface is converted into a state, during which state said USB interface is disconnected electrically to the external peripheral device, thereby stopping the electrical power supply to the external peripheral device; a load switch, mounted on said USB interface wherein, when the required current for operating the external peripheral device exceeds the amount of 2 amperes, said USB interface is converted into a state, during which state said USB interface is disconnected electrically to the external peripheral device; and a USB connector cable including: a main cable having two opposite ends which are adapted to be connected electrically to the external peripheral device and said USB interface for data transmission therebetween, and a power cable extending outwardly and laterally from said main cable between said opposite ends, and having a distal end adapted to be connected electrically to the external peripheral device in order to supply electrical power required by the external peripheral device for operation thereof.
