BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to an electrical adapter for electronically coupling with two electrical connectors, and more particularly to an electrical adapter having an angle formed by a first electrical connector unit and a second electrical connector unit to electronically couple with the electrical connectors in a limited space. [0003] 2. The Related Art [0004] Most electrical devices, such as desktop computers, notebook computers, mobile phones, digital cameras, digital recorders, personal digital assistants (PDA), universal serial bus (USB) disks, etc., are equipped with USB connectors. The electrical devices are popular and easy for use, furthermore, the electrical devices achieve more function by way of electronically coupling with another electrical device equipped with USB connectors. [0005] However, the electrical devices have quite volume and then electronically coupling with the electrical devices in a limited space is not conveniently. For example, the USB disk typically includes a rigid housing having a USB connector. The notebook computer is typically provided with a USB connector at the rear end of the notebook computer. The USB connector of the USB disk is connected with the USB connector of the notebook computer. When the USB connector of the USB disk and the USB connector of the notebook computer are connected, the USB disk is protruded at the rear end of the notebook computer. That is, the rear end of the notebook computer needs an increased space. Therefore, it is not convenient to connect the USB disk to the notebook computer. SUMMARY OF THE INVENTION [0006] An object of the present invention is to provide an electrical adapter for electronically coupling with two electrical connectors, which comprises a first electrical connector unit, a second electrical connector unit and a printed circuit board (PCB). The first electrical connector unit comprises a first metallic cover receiving a first insulating housing and a plurality of terminals and an engagement piece for engaging in the second electrical connector unit. The second electrical connector unit comprises an engagement receptacle for engaging the engagement piece. The PCB is received in the first electrical connector unit for connecting the first electrical connector unit and the second electrical connector unit. [0007] Another object of the present invention is to provide an electrical adapter for electronically coupling with the electrical connectors. The engagement piece forms an angle with respect to the first metallic cover, so that the first electrical connector unit and the second electrical connector unit form an angle which is the same as the angle formed by the engagement piece and the first metallic cover. Therefore, the first electrical connector unit and the second electrical connector unit are engaged in a limited space. [0008] An further object of the present invention is to provide an electrical adapter, which further comprises a shell receiving and protecting the first electrical connector unit, the second electrical connector unit and the PCB.
