Electrical plug connector

Plug comprising a plurality of contact elements arranged in a plug housing and strain relief elements arranged on the housing, wherein the contact elements and the strain relief elements can be fixed to a printed circuit board using SMT technology, wherein the strain relief elements are sheet metal elements that can be fixed to parts of the plug housing and are bent off substantially at a right angle on the side facing the printed circuit board, thereby forming a supporting surface for SMT fastening, wherein the sheet metal elements are fastened to webs used for reverse polarity protection, wherein the webs protrude beyond the plug housing both in the mating direction and also transversely to the mating direction, wherein the sheet metal elements can be fixed by latching connections to the webs, wherein the sheet metal elements comprise four latching connections, which are subdivided into two groups of two latching elements each, and wherein the first group is arranged as close as possible to the upper side of the plug and the second group as close as possible to the printed circuit board.
