Abstract

Two-dimensional variable capacitor is can only the technological invention of single axial electric capacity variable for solving variable capacitor.Form primarily of two movable Loadings On Hemispherical Shells, the sheet metal (C) of episphere housing (8) outer layer surface attachment one design, attachment one piece of magnet (9) in housing; Sheet metal (A, B of lower semisphere housing (5) inner layer surface attachment two design,) due to the directive property effect of magnet (9), when main casing (1) does horizontal plane rotary motion, episphere housing (8) can be done X axis angle and move, main casing (1) does vertical plane rotary motion, lower semisphere housing (5) under gravity, do Y-axis angle to move, namely the sensing of magnet (9) and the physical characteristic of gravity sag is utilized, main body is done or is rotated, and all will change the capacitance of X, Y-axis electric capacity.Two-dimensional variable capacitor, energy consubstantiality biaxially electric capacity variable, rotating shaft also need not apply torsion, for the exploitation of torsionless rotary encoder lays the foundation.

Description

Two-dimensional variable capacitor

Technical field:

Two-dimensional variable capacitor, being can only the technological invention of single axial electric capacity variable for solving variable capacitor, must applying torsion just workable pattern, for the exploitation of torsionless rotary encoder lays the foundation simultaneously for solving on variable capacitor rotating shaft.

Background technology:

Existing variable capacitor technology, be formed by the moving plate of the metal material be parallel to each other and stator and spacer medium group structure, rotating moving plate can change capacity, and it exports, and no matter unit is how many, be all the electric capacity variable of single axial, and rotating shaft must could work by applying torsion.

Summary of the invention:

Two-dimensional variable capacitor, is formed primarily of two Loadings On Hemispherical Shells, the sheet metal of upper hemispherical shell external aspect attachment one design, attachment one block of magnet in housing; The sheet metal of lower semisphere housing inner layer surface attachment two design, due to the directive property effect of magnet, episphere housing can be done X axis angle and move, lower semisphere housing under gravity, do Y-axis angle to move, namely utilize the sensing of magnet and the physical characteristic of gravity sag, two-dimensional variable capacitor main body does or rotates, and all will change the capacitance of X, Y-axis.

Accompanying drawing illustrates:

Fig. 1 is structural representation; Fig. 2 is vertical view; Fig. 3 is the A-A profile of vertical view; Fig. 4 is the B-B profile of vertical view, and wherein 1 is main casing, and 2 is axle bed double adjustment screws, and 3 is cross global shells, 4 is episphere housing axis, and 5 is lower semisphere housings, and 6 is axis pin bases, and 7 is bearing pins, 8 is episphere housings, and 9 is magnet, and 10,11 is metal garden pendant blocks; Fig. 5 is the main pseudosection of lower semisphere housing; Fig. 6 is the main pseudosection of episphere housing; Fig. 7 is lower semisphere housing vertical view; Fig. 8 is episphere housing upward view, and in Fig. 7,8, A, B, C are sheet metal and the contact conductor positions of electric capacity.

Embodiment:

One, A, B are moving plate group, and C is stator.

Two, magnet selects high magnetic steel as far as possible, and except requiring symmetry, the visual feelings of geometry more become.

Three, axle and axle bed stainless steel, and corresponding coupling, bearing pin and axle bed are done to embed global shell design.

If four, overall dimension and capacitance metal sheet figure are not contrary to principle, also can otherwise designed, according to demand simultaneously, matching design external stability.

Five, electrode outlet line can not the flexible turn of stymie housing.

Six, material selection, production technology, operative norm, can refer to the relevant industries such as variable capacitor, compass specification.
