Abstract
Abstract 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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
169 words
In an assembly comprising an adjustable capacitor fixed to a printed circuit, the capacitor comprising a ceramic stator carrying a first plate and having a dielectric layer adjacent the first plate, a rotor formed of a metallic member having a recessed surface adjacent the dielectric layer, said rotor forming a second plate and being rotatably mounted on a conducting axle, and elastic means for axially urging the rotor against the stator, the improvement comprising a continuous metallic layer extending at least partially over two parallel surfaces of the ceramic stator, said metallic layer on a first surface of the stator forming said first plate, said metallic layer on a second surface of the stator contacting a first conducting part of the printed circuit, the conducting axle of the rotor being fixed to a conducting collar protruding from the second surface of the stator but not contacting said metallic layer, and a connector element arranged to bear against said collar and against a second conducting part of the printed circuit.
Claim 2
Dependent Claim
169 words
In an assembly comprising an adjustable capacitor fixed to a printed circuit, the capacitor comprising a ceramic stator carrying a first plate and having a dielectric layer adjacent the first plate, a rotor formed of a metallic member having a recessed surface adjacent the dielectric layer, said rotor forming a second plate and being rotatably mounted on a conducting axle, and elastic means for axially urging the rotor against the stator, the improvement comprising a continuous metallic layer extending at least partially over two parallel surfaces of the ceramic stator, said metallic layer on a first surface of the stator forming said first plate, said metallic layer on a second surface of the stator contacting a first conducting part of the printed circuit, the conducting axle of the rotor being fixed to a conducting collar protruding from the second surface of the stator but not contacting said metallic layer, and a connector element arranged to bear against said collar and against a second conducting part of the printed circuit.
Claim 3
Dependent Claim
43 words
Assembly according to claim 1, in which the conducting collar is formed by a metallic collar-piece tightly fitted on said conducting axle, said connector element being formed by a conducting layer on the second surface of the stator insulated from said metallic layer.
Claim 4
Dependent Claim
97 words
Assembly according to claim 1, wherein the printed circuit is printed on opposed first and second sides of a support plate, said metallic layer on the second surface of the stator contacting a first part of the printed circuit on the first surface of the support plate, and wherein a spring simultaneously forms said elastic means and said connector element, the conducting collar being formed by a metallic collar-piece tightly fitted on said conducting axle, and the spring connecting a second part of the printed circuit on the second surface of the support plate with the collar-piece.
Claim 5
Dependent Claim
22 words
Assembly according to claim 3, in which an end of said conducting axle is countersunk in the metallic member forming the rotor.
Claim 6
Dependent Claim
48 words
Assembly according to claim 1, in which a metallic pin is insulatingly fixed in an opening in said metallic rotor member at a recessed part of said surface, said pin protruding beyond the recessed part of said surface by an amount equal to the height of the recess.
Claim 7
Dependent Claim
23 words
Assembly according to claim 1, in which the recessed part of the surface of said rotor is filled with an electrically insulating material.
Claim 8
Dependent Claim
18 words
Assembly according to claim 1, in which the rotor comprises means to enable rotation thereof about said axle.
