Plug connector

A plug connector, comprising:

• a main body including a connecting element, a circuit board electrically connected with the connecting element, a soldering element soldered to a rear end of the circuit board, and an inner shell surrounding the circuit board;
• a combination element surrounding the inner shell;
• a protecting element integrally molded with a front end of the combination element and mounted around the inner shell;
• and
• an outer shell surrounding the inner shell, the protecting element fastened to a junction among the connecting element, the inner shell and the outer shell, the combination element having a first buckling assembly and a second buckling assembly disposed to two opposite ends of the combination element facing the protecting element and the outer shell, respectively, the first buckling assembly being buckled with the front of the peripheral surface of the inner shell, the second buckling assembly being buckled with an inner peripheral surface of the outer shell.
