Description

A kind of tunable capacitor box

Technical field

The utility model relates to the electric capacity field, particularly a kind of tunable capacitor box.

Background technology

Electric capacity is the physical quantity that the performance capacitor holds the electric charge ability.Electric capacity is on physics, and it is a kind of static electric charge storage medium, and possible electric charge can forever exist, and this is its feature, and its purposes is wider, and it is indispensable electronic component in electronics, the power domain.Be mainly used in power filter, signal filtering, signal coupling, resonance, filtering, compensate, discharge and recharge, in the circuit such as energy storage, stopping direct current.

The capacitance of existing single capacitor is definite value, so when needing to use the electric capacity of regulation capacitance, must select the electric capacity of capacitance coupling to use, when needs change the capacitance size, will again change the capacitor with Circuit Matching, perhaps and connect a plurality of capacitors to change capacitance, this mode of operation greatly reduces operating efficiency.

The utility model content

Technical problem to be solved in the utility model is for shortcomings and deficiencies of the prior art, needs especially a kind of tunable capacitor box, and this tunable capacitor box capacitor bank of can arranging in pairs or groups arbitrarily changes capacitance, and handled easily is to address the above problem.

The technical problem that the utility model solves can realize by the following technical solutions:

A kind of tunable capacitor box is characterized in that, comprises a box body, be provided with two binding posts on the described box body, in the described box body and be connected to the capacitor of some different capacitances, be provided with a switch on each capacitor, the two pins of each capacitor is attempted by respectively on two binding posts.

In a kind of preferred embodiment of the present utility model, described capacitor is 27, comprises the middle capacitor of the small capacitor of nine 100 μ F, nine 1000 μ F, the large capacitor of nine 10000 μ F.

In a kind of preferred embodiment of the present utility model, the large capacitor of described nine 10000 μ F is arranged side by side on described box body top, the middle capacitor of described nine 1000 μ F is arranged side by side at described box body middle part, and the small capacitor of described nine 100 μ F is arranged side by side in described box body bottom.

Owing to adopted technical scheme as above, the beneficial effects of the utility model are: the capacitor that can open and close according to different use needs different capacitances, easy to operate, only need circuit two is terminated on the binding post, the switch of opening required use capacitor gets final product.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Referring to illustrated in figures 1 and 2, a kind of tunable capacitor box comprises box body 100, is provided with two binding post 200a, 200b on the box body 100, and box body 100 tops are stretched out on the top of two binding post 200a, 200b, and the lower end is arranged in the box body 100.

In the box body 100 and be connected to the capacitor of some different capacitances, in the present embodiment, in the box body 100 and connect 27 capacitors, comprising the middle capacitor C2 of the small capacitor C3 of nine 100 μ F, nine 1000 μ F, the large capacitor C1 of nine 10000 μ F, be respectively arranged with a switch S 1, S2, S3 on each capacitor C1, C2, the C3, the two pins (not shown) of each capacitor C1, C2, C3 is attempted by respectively on two binding post 200a, the 200b.

The large capacitor C1 of nine 10000 μ F is arranged side by side on box body 100 tops, and the middle capacitor C2 of nine 1000 μ F is arranged side by side at box body 100 middle parts, and the small capacitor C3 of nine 100 μ F is arranged side by side in box body 100 bottoms.

The utility model is easy to operate, only need the two ends of operating circuit are attempted by on two binding post 200a, the 200b, by opening capacitor C1, C2, the C3 that satisfies the capacitance requirement, can satisfy the operating circuit of multiple different capacitance demands, the capacitance adjustable extent of present embodiment is 100 μ F～99900 μ F, satisfy the required capacitance of the normal use in laboratory, certainly also can change the capacitance of each capacitor C1, C2, C3, to obtain more suitably capacity valve regulating range.

More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
