Abstract

An electrical receptacle connector includes a metallic shell, an insulated housing, a plurality of upper-row receptacle terminals, and a plurality of lower-row receptacle terminals. The insulated housing is received in the metallic shell. The upper-row receptacle terminals are held in the insulated housing and include a plurality of tail portions protruded from a bottom of the insulation body to be arranged into a row. The lower-row receptacle terminals are held in the insulated housing and include a plurality of tail portions protruded from the bottom of the insulated housing to be arranged into a first row and a second row. The tail portions of the lower-row receptacle terminals are parallel to the tail portions of the upper-row receptacle terminals.
