Plug connector system

The utility model relates to a plug connector system. The plug connector system is provided with a plug connector (1) and a corresponding plug connector (2) which can be connected together in a plugged mode, wherein both the plug connector (1) and the corresponding plug connector (2) are provided with at least two contact matching bodies (5, 6), and the at least two contact matching bodies (5, 6) are in mutual electric contact connection and arranged in a belonging shell. In order to further reduce the plug connector system, plug connector shells can move relative to contact matching body shells (3) according to specifications of the utility model. In addition, the plug connector shell (4) is provided with a connecting plate (8) which points to the corresponding plug connector and extends into the corresponding plug connector shell (7), and the connecting plate extends on the contact matching bodies of the plug connector and acts on the contact matching bodies at a plugged state. A force during plugging can be reduced through the plug connector system, thereby enabling the contact safety not to get poor.
