Abstract
The utility model relates to a fuse with a display for automobiles, belonging to a protective device in electric field. The utility model is composed of a luminous diode and the current limiting resistor thereof which are connected in parallel with a fuse. The luminous diode is connected in series with the current limiting resistor, and then is connected in parallel with the fuse. The utility model has the advantages of simple structure, visual display and convenient maintenance, being suitable for various circuits, and being especially suitable for automobile circuits and other occasions which use fuses frequently.
Description
The utility model relates to a kind of automobile-used fuse with display.Belong to the protective device classification in the electric field.
Fuse in use need be changed because of open circuit as the protector that extensively adopts in the circuit, and this originally is an extremely easy operation.Yet, in the place of more use fuse, for example in the automobile circuit,, will bring bigger difficulty to maintenance as because of a certain fuse open circuit causes fault, especially at the vehicle of night running, difficulty is bigger.If the fuse of open circuit can be shown intuitively, will bring great convenience to maintenance undoubtedly.Unfortunately, no matter be domestic car or imported car at present, this class display all is not set bar none.
Purpose of the present invention is to provide a kind of simple in structure, automobile-used fuse that can intuitively show the band display of the fuse of opening a way.
Fig. 1 is an electrical schematic diagram of the present invention, also is one embodiment of the present of invention.
In Fig. 1, it is in the circuit of U that the load Rz of fuse F inserts voltage, in parallel with F after LED is connected with current-limiting resistance R.When the F operate as normal, LED is not worked by short circuit; When F disconnects, LED work, electrified light emitting.Can conclude fuse open circuit in parallel with it in view of the above.Obviously, the size of current-limiting resistance R will be according to voltage U, the impedance of load Rz and LED rated operational current and decide.The operating current of LED is minimum, is generally a milliampere level.As a kind of embodiment, fuse F, LED and current-limiting resistance R can be encapsulated in the same cavity, (staying the LED inspection hole) makes it consistent with the overall dimension of automobile-used fuse of the prior art.
As another embodiment, LED and current-limiting resistance can be arranged in the fuse base, two contacts are in parallel in two ends and the fuse base, after setting up protective tube, just can play the effect that open circuit shows.
The present invention has simple in structure, intuitive display, and the advantage of convenient for maintaining is applicable to various circuit, The occasion that is particularly useful for the more use fuses such as automobile circuit.
Claims (3)
1, a kind of automobile-used fuse with display is made up of fuse F, LED, current-limiting resistance R, it is characterized in that LED is in parallel with fuse F after connecting with R.
2, fuse as claimed in claim 1 is characterized in that said F, LED and R are encapsulated in the same cavity.
3, fuse as claimed in claim 1 is characterized in that said light-emitting diode and current-limiting resistance thereof are arranged in the fuse base.
