Abstract
To connect an old-model antenna receptacle (40) to a new-model car radio antenna connector (50), a unitary conversion plug is provided which has an outer tubular conductor (19) secured over an insulating sleeve (20), formed with a central opening within which an inner conductor (12, 18) is located. The inner conductor has a pin portion (18) projecting from and fitting into the old-model receptacle, and a bushing-like receptacle portion (15), electrically coupled directly or via a capacitor (FIGS. 7-11) to the pin portion, the bushing-like receptacle portion being adapted to receive a central connecting pin of the new-model antenna plug (50). The outer conductor (19) has a first connecting portion (13) dimensioned to fit into an outer bushing terminal (40a) of the old-model receptacle and a second connecting portion (16) dimensioned to fit into a cup-shaped connecting element (51) of the new-model antenna plug, the elements being respectively retained on the tubular insulating sleeve by barbs, rolled-over surfaces, and stepped regions, and axially dimensioned to fit into the old-model receptacle and project just enough therefrom to permit placement of the new-model plug thereover.
