1. An electrical plug connector, comprising:
a housing (1) with an insertion opening (2) for a complementary plug connector, wherein a projecting connecting flange (3) protrudes on an insertion-side end of the housing (1), which connecting flange (3) has through holes (4) for feeding through a fastener (5);
an insertion-side flange plate (10) with an insertion opening (11) for the complementary plug connector and having mounting bores (12) for connecting to a device wall (G);
a control panel; and
a seal (17) with a central cutout (30) in a region of the insertion opening (2), inserted between the connecting flange (3) and the flange plate (10), wherein the seal (17) with a circumferential sealing lip (18) protrudes radially into the insertion opening (2), and the fastener (5) for fastening the housing (1), the flange plate (10), and the seal (17) to the device wall (G) or the control panel;
wherein an outer edge (14) of the flange plate (10) is bent up towards the housing (1) and overlaps an outer edge of the connecting flange (3), and on a rear side, the seal (17) has an edge (19) bent up towards the housing (1), which edge (19) rises above a rear surface of the seal (17) and overlaps an outer circumferential edge of the connecting flange (3) and which, itself, is overlapped by the outer edge (14) of the flange plate (10);
wherein, in an assembled state, a circumferential edge (14) of the flange plate (10) extends at maximum to a height of the rear side of the connecting flange (3) of the housing (1), and the edge (19) of the seal (17) protruding towards the housing (1) is higher than a rear surface of the connecting flange (3) over an entire circumference of the connecting flange (3) and forms a sealing structure or is provided with a sealing structure;
wherein at locations of the mounting bores (12), sealing grommets (21) are integrally formed onto the seal (17), which protrude upwards towards the flange plate (10);
wherein, in the assembled state, the sealing grommets (21) extend inside the mounting bores (12) of the flange plate (10);
wherein an outer diameter of the sealing grommets (21) corresponds to an inner diameter of the mounting bore (12); and
wherein the sealing grommets (21) end above the lower edge of an accommodating region for a head of the fastener (5) in the mounting bore (12).
