Description

Fuse structure with light display function of fusing status

technical field

The utility model relates to a fuse, in particular to a fuse with a blown indication function.

Background technique

The fuse widely used in electrical products or circuits is an overcurrent protection device, which will cause the current to rise instantaneously when the electrical product fails or the circuit is abnormal. The fuse will melt and disconnect to prevent excessive current from damaging the electronic components inside the electrical product, so the fuse has the function of protecting electrical products and providing circuit maintenance.

However, fuses are usually not used alone in actual use. Generally, there are rows of fuses on the car body or in large power distribution equipment to protect individual electronic components from overcurrent; however, when one of the fuses When the fuse needs to be replaced and repaired, it needs to be checked and confirmed one by one in the row of fuses, which causes troubles in use.

Therefore, there is a structure in which a luminous body is installed in the fuse structure. The structure is that a luminous body is installed in parallel with the fuse between two metal conductive sheets in the fuse body. In normal use, the current is only provided by the fuse. If the fuse passes through, the luminous body will not light up, but when the fuse of the fuse is blown due to overload, the current will pass through the luminous body and make it light up, indicating that the fuse has been blown, which is convenient for rapid replacement and maintenance .

However, this known fuse structure still has the following disadvantages in actual use. Because the illuminant is embedded and accommodated inside the housing of the fuse, when the fuse burns out and cannot be used anymore, the illuminant It must be discarded together with the fuse, thus resulting in a waste of cost, especially under the requirements of environmental protection in today's products, it needs to be further improved; in addition, the manufacturing process of placing the luminous body inside the housing of the fuse is also It is more complicated and the assembly cost is also higher.

Therefore, how to improve and solve the above-mentioned shortcomings is the subject of the present utility model.
