Plug connector

A plug connector comprises an insulation body, a metal housing cladded on the outer surface of the insulation body and two rows of terminals; the insulation body comprises two storage cavities that penetrate forward; the storage cavities comprise two opposite sidewalls; the two rows of terminals comprise contact parts and pins set respectively on the two opposite sidewalls and extend into the storage cavities; the storage cavities are set symmetrically in 180 DEG so that the plug connector can be inserted into the corresponding socket connector in both front and back direction. The plug connector is characterized in that each sidewall of the storage cavities has a structure for twelve terminals; the two rows of terminals comprise a first row of terminals and a second row of terminals; the first row of terminals and the second row of terminals have not preset ultra-high speed signal terminals; the distance of the contact parts of the first row of terminals and the second row of terminals is kept in a preset position, and the pins are offset in a certain amount relative to the corresponding to contact parts for welding. Compared with prior art, the plug connector has the advantages of low manufacture cost, and the power transmission function is satisfied.
