Electrical conductor for conducting electrical current through an opening of a housing wall, and method for production

An electrical conductor for conducting electrical current through an opening of a housing wall, wherein

• the electrical conductor is enclosed, at least in a first sealing segment, by a sealing body made from an elastic material, wherein
• the electrical conductor with the sealing body can be inserted into an opening of a housing wall for sealing between sealing body and housing wall, and wherein
• the electrical conductor has a materially bonded connection with the sealing body, and
• a fastening part is provided on the conductor and has an axial through-opening through which the electrical conductor is inserted,
• wherein the fastening part extends radially, starting from the axial through-opening in a first axial segment which has the maximum radial extension of the fastening part perpendicular to the axial through-opening, and wherein
• the fastening part has, on one side or two sides of the first axial segment, a second axial segment and/or a third axial segment respectively forming a radially circumferential separation region for a casting tool;
• and
• the fastening part has grooves running axially in the axial through-opening of the conductor to the sealing body;
• the sealing body extends with a segment through the entire through-opening, up to the end, via grooves provided for this purpose in the through-opening;
• the axial groves are separated from one another by webs which serve for the radial guidance of the electrical conductor;
• a fixing of the electrical conductor perpendicular to the axial direction is achieved by an abutment of the webs 31 on the electrical conductor;
• and
• the fastening body is undermolded by the sealing body via the through-opening and the grooves.
