Abstract:
1. A Universal Serial Bus (USB) receptacle mateable with a USB plug along a mating direction, the USB plug including a plug shell, wherein: the USB receptacle comprises a plurality of contacts, a holder member made of insulator, a shell made of conductor, and a detection pin made of conductor which is separated and is different from the shell; the holder member holds the contacts and arrange the contacts in a pitch direction perpendicular to the mating direction; the shell surrounds, at least in part, the holder member in a plane perpendicular to the mating direction; the detection pin is made of resiliently-deformable material and is held by the holder member so as not to be in direct contact with the shell; the detection pin includes a first support portion, a second support portion, a first contact portion and a second contact portion; the first support portion supports the first contact portion; the second support portion is positioned outside of the first support portion in a perpendicular direction perpendicular to the mating direction and supports the second contact portion; each of the first contact portion and the second contact portion is movable in a predetermined plane defined by the mating direction and the perpendicular direction; the first contact portion and the second contact portion pinch a part of the plug shell when the USB receptacle is mated with the USB plug; and under a condition where the USB receptacle is not mated with the USB plug, the first contact portion and the second contact portion meet an inequality of “(b−a)<T”, where “a” is a distance to the first contact portion from a center of the USB receptacle in the perpendicular direction, “b” is a distance from the center to the second contact portion, and “T” is a thickness of a normal shell of a normal USB plug compliant with the USB standard.
