1. A universal serial bus (USB) receptacle which is selectively mateable with and removable from a standard USB plug or at least one kind of special USB plug along a predetermined direction, wherein:
the standard USB plug is compliant with a USB standard and comprises a standard shell made of a conductive material; the special USB plug has a structure different from a structure of the standard USB plug and comprises a special shell made of a conductive material; the special shell includes a predetermined section and an identifiable portion, wherein the predetermined section has a shape same as a shape of the standard shell, and the identifiable portion projects beyond the predetermined section in the predetermined direction; the USB receptacle comprises a plurality of contacts, a holding member made of an insulating material, a shell made of a conductive material and a detector made of a conductive material; each of the contacts has a contact part; the holding member holds the contacts and arranges the contacts in a pitch direction perpendicular to the predetermined direction; the holding member has a body portion; the body portion has a plate-like shape which extends in the predetermined direction while having a thickness in a vertical direction perpendicular to both the predetermined direction and the pitch direction; the contact parts of the contacts are arranged on an upper surface of the body portion; the shell encloses the holding member in a plane perpendicular to the predetermined direction; the shell is connected to the standard shell when the USB receptacle is mated with the standard USB plug, and the shell is connected to the special shell when the USB receptacle is mated with the special USB plug; the detector is other than the shell; the detector is held by one of opposite side portions of the holding member not to be directly connected to the shell; the detector has a contact portion; the contact portion is arranged at a position where the standard shell does not reach when the USB receptacle is mated with the standard USB plug; the contact portion is movable in a horizontal plane perpendicular to the vertical direction; the contact portion does not overlap the body portion of the holding member at all in the vertical direction; a lower end of the contact portion is located above the upper surface of the body portion in the vertical direction; and the contact portion is connected to an inside of the identifiable portion of the special shell in the pitch direction when the USB receptacle is mated with the special USB plug. |
