## Background
(A) TECHNICAL FIELD OF THE INVENTION
The present invention relates to a transmission conductor structure, and more particularly to an application structure for an electric wave effect of a transmission conductor, carrying out effectively the suppression of common mode signals, and the guiding-to-scatter suppression of radio wave interference (RFI), electromagnetic wave interference (EMI), crosstalk and electrostatic discharge (ESD).
(B) DESCRIPTION OF THE PRIOR ART
Currently, connectors are very popular. Among these, USB connectors are improved, developed continuously, and the transmission speed thereof increases as well.
However, crosstalk may influence the high frequency transmission of differential signals. Especially, a time differential signal pair and a differential signal pair, or a differential signal pair and a signal pair will subject to crosstalk, causing the instability of the signal transmission upon the high frequency transmission of a connector. Therefore, ground terminals are used for a portion of terminals of an electronic connector to block crosstalk generated among signal terminals and prevent the influence to the transmission speed and high frequency signals of the electronic connector itself. However, the suppression of electromagnetic wave interference is carried out on conventional connectors all by means of traditional shielding.

To achieve the object mentioned above, the present invention proposes an application structure for an electric wave effect of a transmission conductor, capable of solving the problem caused by high frequency crosstalk through the following structure; the structure includes at least one transmission conductor, which includes a first transmission conductor set, where the first transmission conductor set includes a first differential signal transmission set, first signal transmission set and second differential signal transmission conductor set arranged parallel to one another, where common mode signal interference generated from the first differential signal transmission conductor set and second differential signal transmission conductor set is suppressed through a first ground transmission conductor and first power source transmission conductor, and the first transmission conductor is in electric connection with a second transmission conductor set, which includes a third differential signal transmission conductor set, second signal transmission conductor set and fourth differential signal transmission conductor set, where common mode signal interference generated from the third differential signal transmission conductor set and fourth differential signal transmission conductor set is suppressed through a second ground transmission conductor and second power source transmission conductor.
Furthermore, the transmission conductor defines at least one contact portion, bended portion and welded portion with a respective angle ranging from 120 to 150 degrees.
Whereby, the collocated actuation among the first ground transmission conductor, second ground transmission conductor, first power source transmission conductor and second power source transmission conductor allows the best suppression of common mode signals, and guiding-to-scatter suppression of radio wave interference (RFI), electromagnetic wave interference (EMI), crosstalk and electrostatic discharge (ESD).
