Method and modular system for producing a plug-in connector by selecting an insert element

The invention relates to a method for producing a plug-in connector (1) for plug-in connection to a corresponding mating plug-in connector (2). A housing (10) is produced, and the housing can accommodate a contact insert (13), which forms a plug-in surface (11) for plug-in connection to a mating plug-in connector (2) and has at least one electrical contact element (130) for electrical contact withat least one mating contact element (200) of the mating plug-in connector (2). Furthermore, in the method, according to the invention, a plurality of plug-in elements (12) are provided which are intended for use on the plug-in connector (1) and are designed to provide different functions on the plug-in connector (1), at least one insert element (12) is selected from the plurality of insert elements (12), and the selected at least one insert element (10) is connected to the housing (10) during the production of the housing (10), or is joined to the housing (10) after the production of the housing (10). 一种用于制造插接连接器(1)的
