Description:
TECHNICAL FIELD OF THE INVENTION 
     The present invention relates generally to an electric connector, and more particularly to a USB Type-C connector that offers advantages of interference resistance, bettered high frequency performance, and large electric current. 
     DESCRIPTION OF THE PRIOR ART 
     Electric connectors have their own evolution of technology. For example, the early version USB connector, which is commonly referred to as USB2.0, has evolved to the later version of USB3.0 that has a must faster operation speed and then further evolved toward the Type-C version that is even faster than the 3.0 version and allows for plugging at both sides. Such a history of evolution is definitely remarkable and impressed. 
     The USB Type-C connector, although having a faster speed and allowing for double-side plugging so as to ease the uses thereof by users, suffers a severe problem in high frequency operations. The unsolved high frequency issue generally leads to problems of signal transmission and severe interference. 
     SUMMARY OF THE INVENTION 
     An object of the present invention is that by providing an arrangement of a first signal transmission conductor group, a second signal transmission conductor group, and a power transmission conductor group according to functions and positions associated with electric characteristics, advantages of improved interference resistance, bettered performance of high frequency, and large electric current can be achieved. 
     A structure that the present invention adopts to achieve the above object comprises a first signal transmission conductor group for transmission of signals and a second signal transmission conductor group or the power transmission conductor group arranged at one side of the first signal transmission conductor group. The power transmission conductor group comprises two adjacent power differential signal transmission conductors and power transmission conductors respectively arranged at an outer side of each of the power differential signal transmission conductors. The power transmission conductors have a volume width that is greater than a volume width of the power differential signal transmission conductors so as to obtain an advantage of large electric current. Further, considering the structure, the first signal transmission conductor group has an end defining a first signal transmission adaptation section group and the second signal transmission conductor group has an end defining a second signal transmission adaptation section group that is arranged at a side of the first signal transmission adaptation section group. The power transmission conductor group has an end defining a power adaptation section group that is arranged at a side of the first signal transmission adaptation section group or the second signal transmission adaptation section group. As such, with such an arrangement, advantages of interference resistance and bettered performance of high frequency can be achieved. 
     With the above techniques, the severe high frequency interference issue of the conventional electrical connector can be overcome so as to achieve the practical utilization of the present invention. 
     The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings.
