A connector insulator includes signal terminal openings and L-shaped or U-shaped grounding terminal openings. The wing portion and the coupling portion are extended from both lower side edges of the main body, respectively. Thus, the grounding terminal can be engaged with the L-shaped or U-shaped grounding terminal opening. Although the grounding terminal is not in U shape, the grounding terminal and the grounding terminal opening surround the signal terminals. Therefore, the grounding terminal still provides an EMI shielding similar to that of a conventional U-shaped grounding terminal.
