Problems solved by technology

[0005] The fuses currently on the market are generally made of opaque explosion-proof ceramics or other insulating materials due to functional requirements. Therefore, when the fuse inside the fuse is blown, the user cannot Direct detection, and some professional measuring instruments are needed to find out that the fuse of the fuse has been blown and replace it. This detection method is not only cumbersome, but also requires professionals to use professional instruments to cooperate.
[0006] Although there are also some fuses whose body is made of light-transmitting material, for small fuses, it is difficult to find the fuse state of the fuse in the fuse through the user's eyes due to its small overall size.
[0007] As mentioned above, the structure of current fuses, especially small fuses, does not have any fusing indication structure, so that it is difficult for users to distinguish the fuse state of the fuse during specific use, which is the main shortcoming of the traditional technology.

Embodiment Construction

[0033] Such as Figures 1 to 5 As shown, a small fuse with a fuse indicating function includes a fuse unit 10 and a fuse indicating unit 20 .

[0034] The technical solution of the present invention is especially suitable for small fuses, and the small fuses of the present invention are generally widely used in all household appliances, power supplies, and fields where fuses need to be installed.

[0035] The size of the fuse unit with blown indication is not limited.

[0036] Such as figure 1 The fuse unit 10 shown is provided with a main fuse 11 .

[0037] The fuse indicating unit 20 is arranged in the fuse unit 10. When the main fuse 11 of the fuse unit 10 is blown, the fuse indicating unit 20 acts and sends a fuse indicating signal, so that the operator can follow the fuse indicating The signal grasps the fusing state of the main fuse 11 in the fuse unit 10, and immediately replaces the small fuse of the present invention.

[0038] Such as Figure 5 The fusing indicat...

Abstract

The invention relates to a small fuse with a fusing indication function. The small fuse comprises a fuse unit and a fusing indication unit, wherein a main fuse wire and the fusing indication unit are arranged in the fuse unit. Because the fusing indication unit is arranged in the fuse unit, when the main fuse wire in the fuse unit is fused, the fusing indication unit subsequently works and sends a fusing indication signal, and an operator masters the fusing state of the main fuse wire in the fuse unit according to the fusing indication signal. The fusing indication signal which is sent by the fusing indication unit is a signal which can be perceived visually and tactually by the operator. The fusing indication unit sends the fusing indication signal in a mechanical movement mode.

Description

technical field [0001] The invention relates to a fuse, in particular to a small fuse with a blown indication function. Background technique [0002] As we all know, with the improvement of social productivity level, more and more automated electrical equipment that can improve people's quality of life and improve people's work and life efficiency have generally entered people's lives. It is often inseparable from the drive of electricity. In practice, in order to prevent the entire electronic control part from being burned out by the current in the event of a short circuit in the electrical equipment, relevant circuit protection devices are now installed in the electrical equipment, and now The most widely used, cheapest, and best protective circuit protection devices are all kinds of fuses. [0003] The fuse, also known as the fuse, is an electrical component installed in the circuit to ensure the safe operation of the circuit. The function of the fuse is mainly to prote...
