Shielded plug connector with earthing contact and method for assembly of same

A plug connector, comprising

• a metallic plug connector housing;
• a contact carrier which, for the assembly of the plug connector, can be inserted in a plug-in direction into the plug connector housing and which is formed of an electrically insulating material, wherein the contact carrier has the following:
• a cable connection side;
• a plug-in side situated parallel to and opposite the cable connection side;
• a side wall which extends in the plug-in direction and which connects the cable connection side to the plug-in side;
• a plurality of through openings, which extend in the plug-in direction and connect the cable connection side to the plug-in side, as contact chambers for receiving plug-in contacts;
• wherein one of the contact chambers is an earthing contact chamber which is distinguished by the fact that it has a lateral connecting opening to the aforementioned side wall of the contact carrier;
• wherein the plug connector also has the following:
• for each of the contact chambers, a metallic plug-in contact arranged in the associated contact chamber;
• wherein each of said plug-in contacts has a plug-in region at a plug-in end and has a cable connection region at a cable connection end situated opposite the plug-in end, and
• wherein that one of the plug-in contacts which is arranged in the earthing contact chamber is an earthing contact,
• a connecting element for electrically conductively connecting the earthing contact to the plug connector housing,
• wherein a part of the connecting element is arranged in the connecting opening of the earthing contact chamber,
• and wherein the connecting element has a lever arm at a first end and has a contact portion at a second end situated opposite the first end,
• wherein the connecting element, the earthing contact, the contact carrier and the plug connector housing are together configured to, during the assembly of the plug connector, mechanically and thus also electrically connect the connecting element, at its lever arm, to the plug connector housing as a result of the insertion of the contact carrier into the plug connector housing, and to pivot the lever arm inward in the process, whereby, in accordance with the functional principle of a rocker, the contact portion moves outward and thereby mechanically and thus also electrically connects the connecting element, at its contact portion, to the earthing contact.
