Abstract:
1. Method for sealing an electrical coupling piece against moisture in which electrical conductors of a line, which include a casing of insulating material jointly surrounding the conductors, are connected to electrical contact elements of the coupling piece, and where a protective body of insulating material is injection molded around the connecting point between conductors and contact elements and with the inclusion of the sealing element, said method comprising the steps of: at an end of the line, intended for connection to the coupling piece, at least one annular groove extending in the circumferential direction is cut into the casing of the line; and prior to injection molding the protective body, an O-ring sealing element is placed in the groove which rests securely with a corresponding pretension against the lateral borders of the groove, and which is of a material which connects tightly and in a moisture proof manner to the insulating material of the finally produced protective body, wherein the O-ring is pushed in an expanded pretensioned state onto the line and is placed in the groove after the expanded state of the O-ring has ended.
