Description
Technical field
This utility model relates to power board technical field, is specifically related to a kind of power board with power protection.
Background technology
Power amplifier is called for short power amplifier, is commonly called as " microphone ", is equipment most basic in sound system, and its task is handle
Ultra-weak electronic signal from signal source (being then from sound console in professional sound system) is amplified driving speaker to send
Sound.
The effect of power amplifier is exactly the small signals amplification from source of sound or pre-amplifier, promotes audio amplifier sound reproduction.A set of good
The effect of good sound system power amplifier is performed meritorious deeds never to be obliterated.
Power amplifier is a family maximum in all kinds of sound appliances, and it is fainter that source of sound equipment is mainly inputted by its effect
After signal is amplified, produces sufficiently large electric current and be pushed to speaker and carry out the playback of sound.Due to consider power, impedance,
Distortion, dynamic and different ranges and control and regulation function, different power amplifiers is in internal signal processing, circuit design
The most different with in production technology.
The most often there is overload and short circuit phenomenon in existing power board, causes components and parts to be burned.
Utility model content
The purpose of this utility model is the defect for prior art and deficiency, it is provided that a kind of merit with power protection
Put plate.
In order to solve the problem existing for background technology, a kind of power board with power protection of the present utility model, it
Comprise pcb board body, positioning sleeve, power module, electric fuse, overload cut-out, circuit protection module, power amplifier main body；Pcb board
It is mounted on positioning sleeve at the corner of body, pcb board body is separately installed with power module, electric fuse, overload cut-out, circuit protection
Module, power amplifier main body, power module is connected with one end of electric fuse, the other end of electric fuse and one end of overload cut-out
Connecting, the other end of overload cut-out is connected with one end of power source protective module, the other end of power source protective module and power amplification
The power end of device main body connects.
As preferably, described circuit protection module is IDEC circuit brake.
As preferably, described overload cut-out is adjustable overloading switch.
This utility model has the beneficial effect that and facilitates implementation overload protection and short-circuit protection, easy to use, easy and simple to handle, work
Make efficiency high, time-consuming.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Description of reference numerals:
1-PCB plate body；2-positioning sleeve；3-power module；4-electric fuse；5-overload cut-out；6-circuit protection module；7-merit
Rate amplifier main body.
Detailed description of the invention
Below in conjunction with the accompanying drawings, this utility model is further described.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and concrete
Embodiment, is further elaborated to this utility model.Should be appreciated that detailed description of the invention described herein is only used
To explain this utility model, it is not used to limit this utility model.
As it is shown in figure 1, this detailed description of the invention adopts the following technical scheme that it comprises pcb board body 1, positioning sleeve 2, power supply
Module 3, electric fuse 4, overload cut-out 5, circuit protection module 6, power amplifier main body 7；It is respectively mounted at the corner of pcb board body 1
There is positioning sleeve 2, pcb board body 1 is separately installed with power module 3, electric fuse 4, overload cut-out 5, circuit protection module 6, power
Amplifier body 7, power module 3 is connected with one end of electric fuse 4, and the other end of electric fuse 4 connects with one end of overload cut-out 5
Connecing, the other end of overload cut-out 5 is connected with one end of power source protective module 6, the other end of power source protective module 6 and power amplification
The power end of device main body 7 connects.
Further, described circuit protection module 6 is IDEC circuit brake.
Further, described overload cut-out 5 switchs for adjustable overloading.
The operation principle of this detailed description of the invention is: realized the raising of power supply, overload cut-out during use by power module 3
5 regulation resistances, when overload occurs, overload cut-out 5 disconnects, it is achieved open circuit, and circuit protection module 6 realizes short-circuit protection simultaneously,
Power amplifier main body 7 being difficult to breakdown, easy to use, easy and simple to handle, work efficiency is high.
The above, is only in order to the technical solution of the utility model to be described and unrestricted, those of ordinary skill in the art couple
Other amendment or equivalent that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope, all should contain in the middle of right of the present utility model.
