Patent ID: 8647151

Claim:
A contact unit comprising: a ground contact plate placed on a first surface portion of a transmission blade and having a plurality of fixation terminal portions to be fixed to a printed circuit board; a transmission contact terminal group placed on a second surface portion of the transmission blade opposite from the first surface portion and having a plurality of pairs of transmission contact terminals each of which has a fixation terminal portion to be fixed to the printed circuit board and forms a signal transmission path; and a plurality of ground contact terminals each placed between the pairs of the transmission contact terminals adjacent to each other and having a fixation terminal portion to be fixed to the printed circuit board, wherein each of the ground contact terminals has at least one slit to be fitted with at least one fixing piece formed in the ground contact plate via the transmission blade, thereby making a frequency of a noise component occurring at the ground contact terminal become out of a frequency range of a signal transmitted to the signal transmission path.
