Abstract

A method for overmolding at least one line (40) comprises the steps:receiving the at least one line (40) in an opening (14) of a sealing element (10), wherein the opening (34) of the sealing element (10) is substantially complementary in shape to a peripheral geometry of the at least one line (40);mounting the sealing element (10) on a mold (30);overmolding the at least one line (40) received in the sealing element in a region (42) that is adjacent to the sealing element (10) and delimited by the sealing element (10); andremoving from the mold (30) the sealing element (10) and the at least one line (40) received therein and overmolded in a region.

First claim

The invention claimed is:

1. A method for overmolding at least one line, said line including at least one electrical conductor and an insulation jacket, said method comprising the steps:
receiving the at least one line in an opening of a sealing element, wherein the opening of the sealing element is substantially complementary in shape to a peripheral geometry of the at least one line;
mounting the sealing element on a mold;
overmolding the at least one line received in the sealing element in a region that is adjacent to the sealing element and delimited by one side of the sealing element, said sealing element being removable from said at least one line after said one line is overmolded;
removing from the mold the sealing element together with the at least one line received therein and overmolded in a region; and, removing the sealing element from the at least one line that has been overmolded in a region.

2. The method as claimed in claim 1 , wherein the sealing element is broken in order to remove it from the at least one line that has been overmolded in a region.

3. The method as claimed in claim 1 , wherein the sealing element is in plate form.

4. The method as claimed in claim 1 , wherein the sealing element, for mounting on the mold, is introduced at least in part into a sealing element holder formed on the mold.

5. The method as claimed in claim 1 , wherein the sealing element is a plastics component.

6. The method as claimed in claim 1 , wherein the mold comprises a metallic material for dissipating heat during overmolding.

7. The method as claimed in claim 1 , wherein at least two lines are overmolded, wherein the opening of the sealing element comprises at least one opening portion, and wherein, in the receiving step, one of the at least two lines can be introduced into the at least one opening portion and thereby fixed in a designated position relative to the sealing element.

8. The method as claimed in claim 1 wherein said sealing element is intended for single use only and is removed from said at least one line by breaking it.
