The invention discloses a waterproof two side-pluggable
USB connector, which comprises a
metal isolation middle plate, a first terminal group, a second terminal group, and a
metal inner shell, wherein the first terminal group and the second terminal group are arranged at two sides of the
metal isolation middle plate respectively; each of the first terminal group and the second terminal group comprises a touch part and a
welding pin integrated with the contact part respectively; a first insulation body is integrated and formed on the first terminal group to form a first combination body; a second insulation body is integrated and formed on the second terminal group to form a second combination body; the metal isolation middle plate, the first combination body or the second combination body, and a third insulation body are integrated to form a third combination body; the third combination body, he first combination body or the second combination body and an insulated outer shell are integrated to form a fourth combination body; and the metal inner shell sleeves the fourth combination body and a waterproof
adhesive is coated. The problem that the existing in-mold injection molding technology can not integrate complicated components as a whole and waterproof performance is poor can be effectively solved.
