Description
Technical field
It the utility model is related to a kind of protector, and in particular to a kind of anti-led power supply protectors for crossing thermal overload.
Background technology
LED has wide market prospects as green illumination light source, and many public places employ LED as illumination
Light source.With the development of LED illumination and LED power supply extensive use, the protector of LED power supplies seems increasingly
It is important, increasingly it is worth research.But existing protector structure is complicated, uses inconvenience, and effectively LED can not be protected to supply
Power supply, it is impossible to effectively reduce and use potential safety hazard caused by led power supplies, make the reduction of LED power supplies service life.
The content of the invention
The purpose of this utility model is to solve the above problems, and now offer is a kind of simple in construction, plug and play, can be effective
Damage of the situations such as thermal overload to led power supplies was prevented, reduces potential safety hazard, led power supplies can be protected, effectively
Extend the anti-led power supply protectors for crossing thermal overload of its service life.
To achieve the above object, technical solution of the present utility model is：A kind of anti-LED power supplies for crossing thermal overload
Protector, it is characterised in that：Including inside and outside two parts, outside is shell, and outer casing frontispiece has outlet, and outer casing bottom has protection
Device attaching plug；Enclosure is provided with circuit board, inserted sheet and temperature inductor, has singlechip chip, electric current mutual on circuit board
Sensor and indicator lamp, circuit board are connected with inserted sheet and temperature inductor, are connected below circuit board with protector attaching plug.
Further, the singlechip chip 4 is NEC8 positions single-chip microcomputer.
Further, the circuit board 2 is PCB.
Further, the material of inserted sheet 5 is phosphor bronze copper sheet.
Further, the indicator lamp 7 is LED, shares three, color is respectively red, yellow and green.
Further, the shell 1 is made up of the fire-retardant material of import.
The beneficial effects of the utility model：
1. compared with prior art, the utility model can automatically cut off electric current when led power supplies cross thermal overload, and
Pass through indicating lamp display mode；Effectively prevented damage of the situations such as thermal overload to led power supplies, reduce to greatest extent by
In using potential safety hazard caused by led power supplies, led power supplies are protected, effectively extend led power supplies uses the longevity
Life.
2. a protector structure is simple, compact, and plug and play, easy to use, without setting manually, automatic sensing
Monitoring, it is time saving and energy saving.
Brief description of the drawings
Fig. 1 is the utility model schematic internal view；
Fig. 2 is the utility model outside schematic diagram；
Fig. 3 is led power supplies and the utility model side schematic view；
Wherein, 1, shell, 2, circuit board, 3, current transformer, 4, singlechip chip, 5, inserted sheet, 6, temperature inductor, 7,
Indicator lamp, 8, protector attaching plug, 9, outlet, 10, led power supplies, 11, led power supply plugs, 12, led supplies
Electric output port of power source.
Embodiment
In conjunction with accompanying drawing, structure of the present utility model and use are further described：As shown in Fig. 1 Fig. 2 Fig. 3, this reality
With new including shell 1, circuit board 2, current transformer 3, singlechip chip 4, inserted sheet 5, temperature inductor 6, indicator lamp 7, guarantor
Protect device attaching plug 8, outlet 9.This protector is divided into inside and outside two parts, and outside is shell, and outer casing frontispiece is inserted provided with power supply
Mouthful, outer casing bottom is provided with protector attaching plug；Enclosure is provided with circuit board, inserted sheet and temperature inductor, circuit board
Singlechip chip, current transformer and indicator lamp are provided with, indicator lamp shares three, is respectively red, yellow and green, in electricity
Above the plate of road, what is be connected with circuit board has inserted sheet and temperature inductor, and temperature inductor is connected for monitoring inserted sheet with inserted sheet
Temperature, be connected with protector attaching plug below circuit board.
When Led power supplies 10 need work, led power supplies output port 12 is connected with LED lamp group, led is supplied
Electric attaching plug 11 inserts the outlet 9 of protector, is connected with inserted sheet 5, protector attaching plug 8 finally is inserted into indoor electric
Source, now the green light of the indicator lamp 7 on circuit board 2 is bright.When led power supplies 10 overload, current transformer 3 can pass
Delivery signal is to singlechip chip 4, and the green light of indicator lamp 7 on circuit board 2 is gone out, and red colored lamp is bright, and electric current can be automatically cut off, and be made
Led power supplies 10 no longer work, and prevent from damaging；When the working time of led power supplies 10 is long, led power supply plugs
11 and inserted sheet 5 can heating, the temperature inductor 6 on inserted sheet 5 can monitor the temperature of inserted sheet 5, when temperature will reach critical value
When, temperature inductor 6 transmits signal to singlechip chip 4, and now the amber light of indicator lamp 7 on circuit board 2 is bright, and electric current temporarily will not
Cut-out, staff can select to pull out power supply or pull down part lamp group to insert to reduce led power supplies within this time
First 11 and the temperature of inserted sheet 5；Still without pulling out power supply after the temperature of led power supplies plug 11 and inserted sheet 5 reaches critical value
When, electric current can be automatically cut off, and prevent led power supplies 10 to be burned.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this
For the technical staff in field, the utility model can have various knowable changes and change.It is all in principle of the present utility model
Within spirit, made any equivalent substitution, modification, improvement etc., should be included in the scope of protection of the utility model it
It is interior.
