Plug assembly for use in a vehicle

A method for producing a plug assembly, wherein the plug assembly comprises a tube, a sealing element and a plug connector,

• wherein the plug connector comprises a connector body,
• wherein the connector body comprises an annulus located between a sleeve-shaped first casing section annularly surrounding a central longitudinal axis of the plug connector in cross section and a sleeve-shaped second casing section of the plug connector annularly surrounding the central longitudinal axis,
• wherein the first casing section is surrounded by the second casing section and the first casing section of the connector body is connected to the second casing section on a first end section by a first front wall section and the casing sections are open to one another on a second end section, thereby forming a tube receiving side of the connector body,
• wherein the method comprises the following method steps:
• providing the connector body with the sealing element accommodated in the annulus;
• providing the tube;
• inserting the tube into the annulus of the connector body from the tube receiving side, wherein the tube is inserted into the annulus such that the sealing element is arranged between the first casing section and the connection section of the tube;
• deforming the first casing section of the connector body by means of a pressing tool, wherein the first casing section of the connector body is deformed such that an interlocking connection is established between a shaping region of the first casing section of the connector body and the tube,
• wherein the sealing element at least partially protrudes into the shaping region of the first casing section, such that the sealing element is clamped at least sectionally between the first casing section and the tube,
• wherein the first casing section is deformed such that the first casing section directly rests on the tube at least sectionally in a contact region,
• wherein the first casing section comprises a first flank and a second flank, the first flank beginning at a center of the contact region, extending away from the tube receiving side of the connector body and terminating at an end of the shaping region adjacent the first end section and the second flank beginning at the center of the contact region, extending toward the tube receiving side of the connector body and terminating at an end of the shaping region adjacent the second end section, and
• wherein the sealing element is arranged at a distance to the center of the contact region, said distance being selected such that the sealing element is clamped between the first flank of the first casing section and the tube, however, does not protrude into the second flank, such that the sealing element is disposed at least partially within an extent of the first flank.
