Abstract

A connector includes an inner structure divided into first, second, and third components. The first component includes plug contacts disposed so as to form a circular plug face configured for connection to a mating connector. The second component includes a connection block having connection contacts configured for connection of a data line connection. The third component includes a printed circuit board configured to provide an adaptable connecting element between the connection block and the plug contacts. The printed circuit board includes a plurality of layers in a sandwich configuration, the plurality of layers including layers having conductive trace alternating with layers having a dielectric. A first layer having a dielectric is disposed between two layers having conductive trace so as to form a first parallel plate capacitor. A second layer having a dielectric is disposed between two layers having trace so as to form a second parallel plate capacitor. A third layer having a dielectric is disposed between the first and second parallel plate capacitors. At least one of the first and second layers is thinner than the third layer.
