Power adapter assembly structure

The present invention provides a power adapter assembly structure including a housing, a circuit board and an elastic element. The circuit board is fastened in the housing and includes a first abutting surface. The socket is fastened in the housing, disposed adjacent to the circuit board, and includes a second abutting surface. The elastic element is disposed in the housing, connected between the circuit board and the socket, and includes a main body, a first hanging arm and a second hanging arm. The first hanging arm and the second hanging arm are disposed at two opposite ends of the main body, the first hanging arm spatially corresponds to and constantly abuts the first abutting surface, and the second hanging arm spatially corresponds to and constantly abuts the second abutting surface. A first gap is formed between the main body and the first abutting surface, and less than a first length of the first hanging arm extended from the main body. A second gap is formed between the main body and the second abut
