Modular plug-in connector, replaceable module printed circuit board

A modular plug-in connector, comprising:

• at least one connection terminal;
• and
• a printed circuit board module housing which is connected to the at least one connection terminal, the printed circuit board module housing comprising a recess configured for reversibly inserting a module printed circuit board, a voltage input terminal connectable to a voltage source, and a voltage supply contact that is electrically connected to the voltage input terminal,
• wherein the module printed circuit board inserted in the recess is suppliable with electrical energy from the voltage input terminal by the voltage supply contact,
• wherein the printed circuit board module housing comprises a signal line terminal and a signal line contact electrically connected to the signal line terminal, such that data exchange between the signal line terminal and the module printed circuit board inserted into the recess occurs using the signal line contact,
• wherein the printed circuit board module housing further comprises a receiving guide arranged in the recess such that the module printed circuit board is insertable between, on one side, the receiving guide, and, on an other side, the voltage supply contact and the signal line contact, and
• wherein the voltage supply contact is subjected to spring force such that the module printed circuit board positioned between the receiving guide and the voltage supply contact is subjected to force by the voltage supply contact in the direction of the receiving guide.
