Method for producing a multi-core cable and correspondingly produced cable

A method for producing a multi-core cable, wherein the cable comprises at least a first core and a second core, and an outer sheath at least partially surrounding the first core and the second core, wherein an end section of an inner conductor of the first core is electrically conductively connected to a first contact element and an end section of an inner conductor of the second core is electrically conductively connected to a second contact element, the method comprising:

• arranging the first contact element and the second contact element in a contact carrier having a contacting side and a cable side, wherein the contact carrier comprises a first longitudinal channel connecting the contacting side to the cable side, a second longitudinal channel connecting the contacting side to the cable side, a first through-opening crossing the first longitudinal channel, and a second through-opening crossing the second longitudinal channel, wherein at least a section of the first contact element is arranged in a front part of the first longitudinal channel extending between the contacting side and the first through-opening, and at least a section of the second contact element is arranged in a front part of the second longitudinal channel extending between the contacting side and the second through-opening;
• sealing the first longitudinal channel and the first through-opening in a fluid-tight manner by inserting two first sealing pieces into the first through-opening;
• sealing the second longitudinal channel and the second through-opening by inserting two second sealing pieces into the second through-opening;
• and
• forming, in an injection-molding method, a connecting piece connecting the contact carrier to the outer sheath of the cable by overmolding at least a rear section of the contact carrier comprising the first through-opening and the second through-opening and a section of the cable protruding on the cable side.
