The overmold 7 consists of polyethylene (PE), a thermoplastic elastomer, to ensure that it forms a secure bond. Since the jacket 4 of the flat conductor 3 is made of a semi-crystalline thermoplastic, in this case polypropylene (PP), as is the adapter 5, the result is good adherence to both plastics and thus good sealing action against the intrusion of media to the electrical contact points.

FIG. 2 shows the result of the overmolding. This illustrates that the overmolding 7 encapsulates all electrically conductive surfaces as well as portions of the jacket 4 of the contact element 3 and the adapter 5. Thus, a robust and reliable sealing of the connection between the given conductors is provided.

If the adapter 5 is embodied as an integral two-component injection-molded part, as indicated in FIGS. 3 and 4, then its jacket is made of polypropylene (PP). However, the inside gasket 6 serving as the second component can consist of a different material, such as a thermoplastic elastomer or silicone. The adapter is slid onto the exposed end of the electrical conductor before being flattened and electrically connected to the contact plate, until the tapering side of the adapter 5 (on the left in FIGS. 3 and 4) abuts the PVC or silicone insulation of the conductor.
