Terminal set of electrical connector

A terminal set of an electrical connector, comprising:

• signal terminal duos having two signal terminals, the signal terminals being spaced apart transversely, wherein the signal terminals are V-shaped each having a first electrical connection portion and a first fixing portion, and one end of the first electrical connection portion connects to one end of the first fixing portion;
• and
• ground terminal duos having two ground terminals flanking the signal terminal duos, the ground terminals each being spaced apart transversely from, being larger than, and hiding transversely an adjacent one of the signal terminals, wherein the ground terminals are V-shaped each having a second electrical connection portion and a second fixing portion, one end of the second electrical connection portion connects to one end of the second fixing portion, the ground terminals have a smaller transverse width than the signal terminals and are plate-like each, and the first electrical connection portions are spaced apart transversely by a first distance and are each spaced apart transversely from an adjacent one of the second electrical connection portions by a second distance, with the first distance being shorter than the second distance.
