  The present invention relates to an electronic device assembling method and an electronic device.

  FIG. 17 is a diagram showing a configuration of a single-axis hinge USB (Universal Serial Bus) dongle type wireless communication terminal (hereinafter referred to as a single-axis USB terminal) in the related art. FIG. 18 is a diagram illustrating a movable state of the uniaxial USB terminal, and FIGS. 19 and 20 are diagrams illustrating a connection state between the uniaxial USB terminal and the PC (Personal Computer).

  FIG. 21 is a diagram showing a configuration of a biaxial hinge USB dongle type wireless communication terminal (hereinafter, biaxial USB terminal) in the related art. FIG. 22 is a diagram illustrating a movable form of the biaxial USB terminal, and FIGS. 23 and 24 are diagrams illustrating a connection state between the biaxial USB terminal and the PC.

  As shown in FIG. 17, the single-axis USB terminal in the related art includes a USB connector unit 1 ′ connected to a PC at the center x1 ′ of the terminal. However, if there is a USB connector unit 1 ′ at the center x1 ′ of the terminal, it is connected as shown in FIG. 20 when the terminal is connected to a PC having USB ports 22a and 22b arranged in parallel like the PC 22. The other USB port 22b is blocked by the terminal. Therefore, there is a problem that other USB devices cannot be connected to the PC 22. This problem can be solved by bringing the USB connector unit 1 ″ to one side of the terminal and making the hinge biaxial as shown in FIG. That is, since the thickness direction of the terminal and the direction of connection to the USB port are parallel when connected to the PC, it is possible to open the adjacent USB port even if the terminal is connected to the PC. However, two hinge units must be used to make the hinge biaxial. When two hinge units are used, the cost increases, the thickness of the device increases as the number of components increases, and another problem arises that the terminal bottoms out when connected to a thin notebook PC.
