  • Patent number: 10581204
    Abstract: The present invention effectively prevents a short circuit from occurring between a power supply terminal and a ground electrode. A receptacle-side connector (3) includes a metal plate (mid-plate 32) and a shell part (23). An edge surface (end surface part 32a) of the metal plate, which edge surface is located at an end surface facing a first side toward an opening (23a) of the shell part (23) and which corresponds to a position of a power supply terminal (Vbus terminal 25), is shaped so as to be set back toward a second side opposite the first side.

  • Patent number: 7835775
    Abstract: A cellular phone includes a first case and a second case, which are connected in a foldable manner through a hinge. When the cellular phone is in a folded state, a second display unit displays an image with the side (upper side) closer to the hinge as the upper side. Accordingly, the user can hold the second case of the cellular phone in his/her hand regardless of whether the cellular phone is in a folded state or in an open state. The user can easily switch between a folded state and an open state with respect to the first case and the second case.
