Abstract
The utility model provides a hole on the existing fuse for mounting a luminous element and a resistor, so that the purpose of automatic display when a fuse wire is burned out is obtained. The utility model has the advantages of simple structure, low cost. The use is the same as the use of common fuse devices.
Description
The utility model relates to the fuse field.
General ceramic pluging type fuse is had no progeny at fuse, has cut off circuit, but can not show.This not only makes troubles to the Inspection person of repairing, and makes the three-phase middle and small motor often burn motor because of the two-phase running, makes household appliances shell often because of repeating the charged security incident that causes of connecting to neutral.Though screw type fuse can show, obvious inadequately, and price is more expensive.
The purpose of this utility model provides a kind of can obviously the demonstration, and cheap light display type fuse.
The utility model is only in the hole that covers out of existing ceramic pluging type fuse, and on fuse and connect a display circuit.
Below in conjunction with embodiment accompanying drawing of the present utility model is made an explanation.
Accompanying drawing is a working circuit diagram of the present utility model.
See that this circuit of accompanying drawing is made of two branch roads of parallel connection: a branch road is a fuse circuit, and another road is to comprise that neon bulb and resistance are the display circuit of 100K Ω～2M Ω.
Under the normal condition, because of the resistance of fuse (1) much smaller than resistance (2), so the essentially no electric current of neon bulb branch road, thereby neon bulb (3) does not work.In case fuse is during because of the excessive fusing of electric current, the neon bulb branch road becomes the loop, and neon lamp sends eye-catching ruddiness, and the expression fuse fuses.Because the metering function of resistance (2), this moment, circuital current was very little to have no effect to electrical appliance.
The utility model is perforate installation neon bulb and resistance on former fuse only, has the characteristics such as simple in structure, that cost is low.
Claims (3)
1, a kind of light display type plug-in fuse is characterized in that the hole that covers out at fuse, and on fuse and connect a display circuit.
2, light display type fuse according to claim 1 is characterized in that display circuit is made up of neon bulb and resistance.
3, light display type fuse according to claim 2 is characterized in that resistance is 100K Ω～2M Ω.
