Abstract

The mechanical connection of contacts through induction soldering is improved. To which end, a plastic dome is produced through preliminary encapsulation by injection molding of at least one contact and subsequent final encapsulation, where the two contact geometries to be joined can, for example, be premated. With an appropriate solder preform, the plug-in connection can be secured through induction soldering by enclosing this dome. The appropriate tool is then placed over the plastic dome, by which the heat generated melts the solder preform and securely joins the two contacts to one another.
