Abstract

The utility model discloses a plug connector including a plug module and a connection line connected to an end part of the plug module. The plug module includes a terminal module. A plurality of conducting terminals are embedded into the terminal module. Contact ends of the conducting terminals are exposed on the upper surface and the lower surface of the front end of the terminal module. The plug module also includes a lining shell and an outer shell. The terminal module is connected with the connection line. The lining shell includes a first lining shell and a second lining shell wrapping the terminal module in a vertically-buckling manner. The head end of the terminal module protrudes outside the lining shell, so that a connection-peg is formed. The shell covers the lining shell. Therefore, a split assembling structure is adopted according to the utility model, so that a test can be performed directly after the lining shell is installed. Once the plug connector does not pass the test, the assembled plug connector can be disassembled for reassembling and the expensive terminal module is not damaged, so that aims of reducing rejection rate in a production process and reducing production cost are realized.
