Abstract

An electrical connection plug includes an insulating base, a metal housing, and a fitting portion. The left and right sides of the metal housing are shaped to have semi-circular arc structures. The upper and lower surface and the left and right sides of the metal housing that perpendicularly correspond the fitting space are formed to have hole-free structures. The height of the two contact interface substrates is smaller than the height 0.9 mm of a fitting interface substrate of a biased electrical connection plug having the minimum height specification specified by USB Association and larger than 0.28 mm. The height of the two contact interface substrates enables the two contact interface substrates to tightly fit the two spaces.
