Abstract
The utility model provides a power amplifier capacitor case, which comprises a plurality of small capacitors, a circuit board, a case cover, a base plate, side plates and circuit board interfaces, wherein the small capacitors are divided into at least two rows arranged on the circuit board; the side plates are fixed on both ends of the circuit board; the circuit board interfaces are mounted on the side plates, and are connected with the circuit board; the base plate is positioned under the circuit board; and the case cover covers the circuit board, and is connected with the base plate. The power amplifier capacitor case adopts three rows of small capacitors. The overall size of the capacitor case is reduced, so that the mounting space is saved; moreover, when one of the small capacitors is burnt, other small capacitors still can continue to operate, and thereby the service life of the capacitor case is greatly prolonged. The wavy heat-dissipating areas on both sides of the case cover can greatly enhance the heat dispersion of the power amplifier capacitor case.
Description
Technical field:
The utility model relates to the power amplifier technology field, refers in particular to a kind of power amplifier electric capacity box.
Background technology:
Being used in the power amplifier electric capacity box on the automobile at present, is to adopt a big electric capacity mostly, then big electric capacity is assemblied in a columniform can, can is fixed in the car again.Adopt the electric capacity box of this class formation, one, because electric capacity is bigger, and interior space is to take greatlyyer, installs also inconvenient; Its two owing to only adopted a big electric capacity, after electric capacity breaks down, just must change a whole set of electric capacity box, what increased the car owner greatly uses the car cost, is a kind of waste to resource.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of compact conformation, thermal diffusivity that adopts a plurality of little electric capacity to substitute big electric capacity work is good, the power amplifier electric capacity box of long service life.
For achieving the above object, technical scheme provided by the utility model is: a kind of power amplifier electric capacity box, and it includes little electric capacity, circuit board, and it also includes lid, base plate, side plate, circuit board interface, wherein, is arranged on the circuit board after a plurality of little electric capacity parallel connections; Side plate is fixed on the circuit board two ends; Circuit board interface is installed on the side plate, and is electrically connected with circuit board; Base plate is positioned at the circuit board below; Lid covers the circuit board top, and is connected with base plate.
Described side plate is provided with location notch, and the lid two ends are provided with the locating piece that matches with location notch.
Described lid is provided with the display screen that is electrically connected with circuit board.
Described little electric capacity is divided into three rows, is evenly arranged on the circuit board.
The utility model is after having adopted the little electric capacity of three rows.Both dwindle the overall volume of electric capacity box, saved installing space; And after wherein some little electric capacity burnt out, other little electric capacity can also work on, and had increased the useful life of electric capacity box greatly.The waveform radiating area of lid both sides can be accelerated the heat dispersion of power amplifier electric capacity box greatly.
