US Patent 7857659 Electronic device with stretchable USB receptacle

An electronic device having a stretchable USB receptacle is provided. An extending connecting cable is added to the USB receptacle on the electronic device. In normal condition, the connecting cable is accommodated in a cable reel to make the USB receptacle accommodated in an accommodating recess of the electronic device to keep consistency of the appearance. In using condition, the USB receptacle may be taken out and used in a needed place by drawing out the connecting cable. This overcomes the disadvantage that the conventional adjacent USB receptacles may be interfered with each other, and the scope of use also increases.
