A USB connecting apparatus includes a board member, a plurality of first conductive connection portions, a metal housing and an assembly structure. The board member is a printed circuit board complying with the USB-Type C specification and includes a main body portion and a tongue portion. The tongue portion includes two surfaces facing toward each other. Each first conductive connection portion is electrically disposed on at least one surface of the tongue portion in order to form a tongue plate. The metal housing is arranged on the board member and surrounds the tongue plate correspondingly. The assembly structure is arranged on the plate member and/or the metal housing. The plate member and the metal housing are positioned relative to each other via the assembly structure. Accordingly, the USB connecting apparatus can be used on an existing electronic product circuit board and can be directly used as USB Type-C.
