Abstract: A USB connector, a PCB connected to the USB connector, and a USB device are provided. The USB connector includes a metal surface, and on the metal surface, a solid metal part is set at a location corresponding to a spring of a socket, so that the spring contacts the solid metal part after the USB connector is inserted into the socket to reduce electromagnetic interference. The USB connector may include an in-line weld leg; a metal enclosure located at the same side as the in-line weld leg fully contacts a PCB when the USB connector is connected to the PCB; and contact surfaces on the USB connector that contact the PCB are metal surfaces. The PCB includes a suppression circuit configured to suppress harmonic waves in USB data transmission.

Abstract: An improved Universal Serial Bus (USB) connector apparatus is provided. In one embodiment, the USB connector apparatus comprises a top wall; a bottom wall having one or two openings; two side walls; an internal cavity with a rectangular cross section enclosed by the top wall, the bottom wall and the two side walls; a gasket disposed within the internal cavity; and a first connecting piece made of a conductive material and positioned at the one or more openings of the bottom wall and at least partially covering the one or more openings of the bottom wall, wherein the top wall, bottom wall, two side walls, internal cavity and gasket are configured to comply with a USB interface standard. The USB connector apparatus ensures that a bottom wall elastic sheet of the USB socket effectively contacts with the bottom wall of the USB connector, thereby providing higher grounding performance. Further, it improves on the conventional USB connector without much additional cost.
