Abstract
The utility model relates to a display of a fuse box for electrical equipment, which belongs to the field of electronic lines. The aim of the utility model is to solve the problem that failure position can not be rapidly found when the fuse is fused. The utility model is characterized in that a resistor R is connected in parallel with the fuse F after connecting in series with a light-emitting diode LED; when the fuse is fused, the light-emitting diode automatically lights, and thereby, the accurate position of the fuse can be directly displayed by means of emitting light.
Description
Affiliated technical field
The utility model relates to field of electronic circuitry, especially a kind of electric equipment fuse box display.
Background technology
At present, the development of various power consumption equipments and household electrical appliance universal day by day, and cars ' entry into family, when these equipment and instrument ifs circuit break down, fuse quantity in blown fuse, the especially automobile circuit is more, and searching when certain blown fuse wastes time and energy.
Summary of the invention
The technical deficiency that is difficult to search when overcoming existing circuit blown fuse, the utility model provides a kind of electric equipment fuse box display, when in the circuit during certain blown fuse, light-emitting diode is lighted automatically, thereby can directly demonstrate the blown fuse at this position.
The technical scheme that its technical problem that solves the utility model adopts is: in parallel with fuse F after resistance R is connected with LED.When fuse F fuses, resistance R and LED conducting, the LED build-up of luminance, thus point out the blown fuse at this place, be able to directly search the purpose at guilty culprit position.
The beneficial effects of the utility model are, when blown fuse, and the light-emitting diode build-up of luminance, thus point out the blown fuse at this place, can directly find out trouble location, simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is circuit theory diagrams of the present utility model, also is an embodiment schematic diagram.
Fig. 2 is the circuit theory diagrams of second embodiment of the utility model.
1. resistance among the figure, 2. light-emitting diode, 3. fuse.
Embodiment
In Fig. 1, it is in parallel after resistance (1) is connected with light-emitting diode (2) with fuse (3), when electric equipment breaks down, fuse (3) fusing, the branch road conducting that resistance (1) and light-emitting diode (2) are formed, light-emitting diode (2) energising is by build-up of luminance, thereby the form of using up demonstrates fuse (3) fusing at this position.
In Fig. 2, light-emitting diode (2) is directly in parallel with fuse (3), and when fuse (3) disconnected, light-emitting diode (2) conducting was lighted, thereby the fusing fault takes place the fuse that shows this place.
Claims (1)
1, a kind of electric equipment fuse box display is characterized in that resistance R is in parallel with fuse F after connecting with LED.
