Abstract

The present disclosure provides a power adapter including a first housing, a second housing, a circuit board, an electrical connector and a power cord. The first housing and the second housing are assembled together and define an interior space. The circuit board is accommodated in the interior space. The electrical connector is electrically connected with the circuit board and includes an insulation body and plural pins. The insulation body comprises a concave and a bottom wall, and the insulation body and the first housing are integrally formed into one piece. Each pin is partially located in the concave, partially embedded in the bottom wall, and partially extended outwardly from the bottom wall. The power cord is electrically connected with the circuit board.
