Abstract: An electrical connector assembly includes a housing comprising a rear base and a mating tongue extending forward from the base; a row of upper terminals and a row of lower terminals retained on the housing, each terminal including a contacting section exposed to mating tongue and a pin leg section from the base, and the contacting sections of the upper and lower terminals being aligned with each in a vertical direction. The contacting sections of each row terminals are arranged in different central pitch, the pin leg sections of the upper and lower terminals are aligned with each in a front and back direction and the pin leg sections of each row are arranged with a same central pitch.

Abstract: An electrical connector includes a base seat, a plurality of contacts fixed in the base seat, and a shielding shell surrounding the base seat. The shielding shell defines a body portion retained in the base seat, a rear wall attached a rear face of the base seat and a plurality of soldering portions extending outside of the body portion. The electrical connector defines a mounting surface, a lower edge of the rear wall is higher than the mounting surface and defines at least one board-lock portion to improve the resonant frequency.
