Description
Technical field
The present invention relates to protection device, and in particular to the apparatus for protecting power supply based on power amplifier.
Background technology
Power supply is the necessary important component of electronic equipment, is the dynamic foundation of electronic equipment, and protection power source is normally transported
Row is the basis for ensureing electronic equipment normal work.
Power amplifier needs to stablize lasting power supply at work, and needs to ensure no any electronic interferences as far as possible
Generation, just can guarantee that the normal work of power amplifier.
Now with increasing for electronic equipment, electronic interferences are also more and more, and intensity also increases therewith, protection power source not by
Interference, and ensure the indispensable part of power amplifier normal work.
The content of the invention
It is big that the present invention to be solved prior art electromagnetic interference, the problem of influenceing power input stability, there is provided based on work(
The apparatus for protecting power supply of rate amplifier, reduce electromagnetic interference.
The present invention is achieved through the following technical solutions：
Apparatus for protecting power supply based on power amplifier, including power amplifier, fin, ferrite bean, shell；Institute
State the outer wall that fin is arranged on shell；The ferrite bean is arranged on the outer wall of shell；The shell is internally provided with
Mounting hole.The radiating of power supply is provided by fin, the ferrite bean can effectively reduce electromagnetic interference.
Further, the fin is shaped as circle, and hole is provided with the axle center of the fin, the diameter in the hole
The diameter of the shell is matched, and shell is arranged among the hole.
Further, the ferrite bean includes upper casing, lower casing and ferrite body, and the upper end of the upper casing is set
There is heat emission hole, the ferrite body is arranged between upper casing and lower casing.
Further, every three groups of fins are into one group of radiating group, at least 3 groups of the radiating group.
Further, the material of the shell is flame retardant plastics.
Further, the material of the fin is iron.
The present invention compared with prior art, has the following advantages and advantages：
1st, the apparatus for protecting power supply of the invention based on power amplifier is simple in construction, easy for installation；
2nd, the apparatus for protecting power supply of the invention based on power amplifier effectively reduces electromagnetic interference；
3rd, the apparatus for protecting power supply good heat dissipation effect of the invention based on power amplifier.
