Plug-in connector

Plug-in connector, in particular for a high-current application, with an electrically conductive plug-in contact element and an electrically insulating housing, the housing having at least one through-opening forming a plug-in contact element holder for receiving the plug-in contact element, the plug-in contact element holder surrounding the plug-in contact element at least in regions and a seal being provided in the region in which the plug-in contact element holder surrounds the plug-in contact element so that the seal seals the plug-in contact element holder to the plug-in contact element, and the plug-in contact element having a crimp section for establishing an electrical and mechanical connection to a cable, wherein the plug-in contact element has a latching element and the corresponding plug-in contact element holder has a mating latching element so that the plug-in contact element is latched and held in the plug-in contact element holder to prevent a movement of the plug-in contact element counter to a plug-in direction, the plug-in contact element being formed from a crimp element and a plug-in element which are connected to one another by means of a press fit prior to insertion into the housing.
