11279093 · 2022-03-22 · ·

A connection arrangement includes a first plastic component, a second plastic component, and a closed induction ring. The first plastic component has a first joining region designed as a receptacle, and at one end, the second plastic component has a second joining region introduced into the first joining region. At the joining regions, the induction ring is at least partially fused into the two plastic components such that at one contact region between a first plastic melt of the first plastic component and a second plastic melt of the second plastic melt, a material-conclusive connection is generated. In this case, the induction ring is melted into the first plastic component while forming at least one first undercut, and is melted into the second plastic component while forming at least one second undercut such that between the plastic components and the induction ring, one each form-fitting connection is created.
