ASSEMBLY COMPRISING AN ADJUSTABLE CAPACITOR AND A PRINTED CIRCUIT

摘要

A capacitor, fixed to a printed circuit, comprises a ceramic stator with a continuous metallic layer extending partially over two sides thereof. One side of this layer forms the first plate of the capacitor and the other side is connected to a first part of the printed circuit. A metallic rotor member having a recessed surface is applied by elastic means against a dielectric layer adjacent said one side of the stator. The rotor is mounted on a conducting axle extending through the stator and terminating with a conducting collar protruding from the other side of the stator but not contacting the metallic layer. A connector element, for example either a further conducting layer on the other side of the stator or a spring, connects the collar to a second part of the printed circuit.
