Abstract
A variable capacitor, including: two movable plates, two poles, and one rotary shaft. The two movable plates are conductor belts, and the conductor belts are sheathed in insulators. The two poles are conductors, and each is capable of rotating around an axis thereof. First ends of the two movable plates are connected via the insulators and fixed on the rotary shaft, and second ends of the two movable plates are connected to the two poles, respectively. A conductor member of the two movable plates directly contacts the two poles. The lengths of the two movable plates are identical, and are greater than the distance from one pole to the rotary shaft.
Claims15
A variable capacitor, comprising:
- two movable plates, the two movable plates being conductor belts;
- two poles;
- and
- one rotary shaft;
- wherein
- the conductor belts are sheathed in insulators;
- the two poles are conductors, and each is capable of rotating around an axis thereof;
- first ends of the two movable plates are connected via the insulators and fixed on the rotary shaft, and second ends of the two movable plates are connected to the two poles, respectively;
- a conductor member of the two movable plates directly contacts the two poles;
- and
- lengths of the two movable plates are identical, and are greater than a distance from one pole to the rotary shaft.
A method for manufacturing a variable capacitor, comprising:
- coating two conductor belts with insulators to form two movable plates;
- connecting first ends of the two movable plates together via the insulators and fixing the first ends on a rotary shaft;
- fixing second ends of the two movable plates on two poles, respectively, wherein the two poles are conductors, and each is capable of rotating around an axis thereof;
- allowing a conductor member of the two movable plates to directly contact the two poles, wherein the two poles are used for wiring, and lengths of the two movable plates are identical, and are greater than a distance from one pole to the rotary shaft;
- and
- rolling or unrolling the conductor belts to change a capacitance of the capacitor.
