1. Field of the Invention
The present invention relates to a fuse, and in particular to a fuse assembly with a function of indicating a state of a fuse by light.
2. Description of Prior Art
The fuse is an over-current protection device that is widely used in electronic products or circuits. When the electronic product suffers damage or the circuit is in an abnormal state, the current will rise instantaneously. When the current flowing through the fuse exceeds its maximum capacity, the fuse will be blown to prevent the excessive current from damaging the electronic elements within the electronic product. Therefore, the fuse can protect the electronic product and can be used to check a circuit.
In practice, more than one fuse is used in an electronic product. A car or a large-scale power-distributing apparatus is provided with rows of fuses, thereby protecting the electronic elements against an over-current respectively. However, when one of the fuses is blown or needs to be replaced or checked, the operator has to check the rows of fuses one by one, which causes a lot of inconvenience in use.
Therefore, a fuse assembly combined with a light-emitting body is proposed. The light-emitting body is provided with a casing of the fuse assembly. Specifically, the light-emitting body is disposed between two metallic conductive pieces and in parallel to the fuse. In a normal state, the current only flows through the fuse without passing through the light-emitting body, so that the light-emitting body does not illuminate. When the fuse is blown due to an over-current, the current will flow through the light-emitting body, so that the light-emitting body illuminates to indicate the blowing of the fuse. In this way, it is convenient for the operator to check and replace the damaged fuses.
However, in practice, the above-mentioned fuse assembly still has some drawbacks as follows. Since the light-emitting body is inserted and accommodated in the casing of the fuse assembly, when a fuse is blown, the light-emitting body is thrown away together with the damaged fuse, which causes the waste of materials and money. Especially, in order to conform to the requirement for environmental protection, it is necessary to improve such a fuse assembly. On the other hand, the manufacturing procedure of mounting the light-emitting body within the fuse assembly is more complicated. Also, the cost of assembling is larger.
Therefore, it is an important issue for the present Inventor to overcome the above problems.
The present invention is to provide a fuse assembly with a function of indicating a state of a fuse by light, whereby light-emitting diodes can be recycled to reduce the material cost and the requirement for environmental protection can be satisfied.
The present invention is to provide a fuse assembly with a function of indicating a state of a fuse by light, whereby the manufacturing process can be simplified to reduce the manufacturing and assembling cost.
The present invention is to provide a fuse assembly with a function of indicating a state of a fuse by light, which includes a fuse body formed therein with an accommodating space, a side surface of the fuse body being provided with an accommodating hole; two conductive terminals accommodated in the accommodating space of the fuse body; and a light-emitting diode inserted into the accommodating hole of the fuse body, thereby electrically connecting the light-emitting diode to the two conductive terminals. By the above arrangement, the light-emitting diode can be lighted up when the fuse body is blown.
The detailed description and technical contents of the present invention will be explained with reference to the accompanying drawings. However, the drawings are illustrative only but not used to limit the present invention.

Therefore, according to the present invention, after the fuse is blown, the light-emitting diode 30 can be taken out of the accommodating hole 131 of the fuse body 10, thereby recycling the light-emitting diode 30 to reduce the material cost and conform to the requirement for environmental protection. Furthermore, the assembling procedure of the light-emitting diode 30 is simple, so that the manufacturing procedure of the present invention is also simplified and the manufacture cost is reduced. Therefore, the present invention has great practicability and economic benefits.
Although the present invention has been described with reference to the foregoing preferred embodiments, it will be understood that the invention is not limited to the details thereof. Various equivalent variations and modifications can still occur to those skilled in this art in view of the teachings of the present invention. Thus, all such variations and equivalent modifications are also embraced within the scope of the invention as defined in the appended claims.
