Description

Technical Field

[0001] This application relates to the field of fuses, and in particular to a light-emitting fuse. Background Art

[0002] The main function of a fuse (usually referred to as a fuse wire or fuse) in a circuit is to provide overcurrent and short-circuit protection. When the current in the circuit exceeds the preset safe value, the fuse wire inside the fuse melts due to overheating, thus automatically disconnecting the circuit. This process effectively prevents excessive current from continuing to flow and prevents equipment damage or fire that may be caused by overload or short circuit.

[0003] In the prior art, in situations such as when a device fails to start or the power indicator light does not turn on, it may be due to the fuse being blown due to overload or short circuit, resulting in an open circuit, or there may be problems with other parts of the circuit. Usually, it is necessary to check for power outage or use a multimeter. Generally, it is difficult to directly determine whether the fuse is working properly.

[0004] In view of the above defects, the present utility model proposes a light-emitting fuse that can visually determine whether the fuse is working properly. Summary of the Utility Model

[0005] This application provides a light-emitting fuse that can visually determine whether the fuse is working properly.

[0007] One end port of the outer shell fixes the power supply side terminal, the other end port of the outer shell fixes the load side terminal, the power supply side terminal and the load side terminal are connected by the fuse wire, the fuse wire is arranged inside the outer shell, the load side terminal is connected to one end of the conductive wire, the other end of the conductive wire extends into the transparent shell, the transparent shell is filled with an inert gas, and the transparent shell is fixed on the outer shell.

[0008] In a possible design, there is an opening on the transparent shell, the conductive wire extends into the transparent shell from the opening, and a sealing gasket is arranged at the opening.

[0009] In a possible design, the inert gas is one or more of neon, helium, argon, xenon, and krypton.

[0037] In view of the above defects, the present utility model provides a light-emitting fuse, specifically for solving the above problems.

[0038] The following will introduce in detail a light-emitting fuse provided by an embodiment of the present application with reference to the drawings.

[0039] Embodiment 1

[0040] This embodiment provides a light-emitting fuse, including an outer casing 100, a transparent casing 200, a fuse wire 300, a power supply side terminal 400, a load side terminal 500, and a conductive wire 600, where

[0041] One end port of the outer housing 100 is fixed with a power supply side terminal 400, and the other end port of the outer housing 100 is fixed with a load side terminal 500. The power supply side terminal 400 and the load side terminal 500 are connected by a fuse 300. The load side terminal 500 is connected to one end of a conductive wire 600, and the other end of the conductive wire 600 passes into the transparent housing 200. The transparent housing 200 is filled with an inert gas, and the transparent housing 200 is fixed on the outer housing 100.

[0042] Specifically, for the fuse provided in the embodiment of the present application, in the normal working state, the load side and the power supply side are conducted through the fuse 300, and the current sequentially passes through the power supply side terminal 400, the fuse 300, the load side terminal 500, and the conductive wire 600 to pass the current into the transparent housing 200. The transparent housing 200 is filled with an inert gas. According to the glow discharge characteristics of the inert gas, the inert gas will emit a specific color of light. Thus, the staff can determine whether the fuse is working properly by observing the transparent housing 200. If a specific color of light is emitted, it is determined that the fuse is working properly; if no light is emitted, it is determined that the fuse is open.

[0043] Specifically, when inert gases (also known as noble gases) are placed in an electric field, they can exhibit a phenomenon of emitting light, and this process is called electroluminescence or glow discharge. The reason why inert gases can emit light is that their electrons transition from the ground state to the excited state under the action of an external electric field, and then when the electrons return to a lower energy level, they will release the excess energy in the form of photons.

[0044] Specifically, when the molecules or atoms of inert gases are collided by free electrons accelerated in an electric field, the electrons can be excited to higher energy levels to form an excited state. The electrons in the excited state are unstable, and they will spontaneously transition back to the ground state or other lower energy levels. In this process, the electrons will release energy, usually in the form of photons, which is the light emission phenomenon we observe.

[0045] Embodiment Two

[0046] Figure 1 is a structural schematic diagram of a light-emitting fuse provided by the present utility model Figure 1 .

[0047] As Figure 1 shown, a light-emitting fuse provided in this embodiment includes an outer housing 100, a transparent housing 200, a fuse 300, a power supply side terminal 400, a load side terminal 500, and a conductive wire 600, wherein

[0048] One end port of the outer housing 100 is fixed with a power supply side terminal 400, and the other end port of the outer housing 100 is fixed with a load side terminal 500. The power supply side terminal 400 and the load side terminal 500 are connected by a fuse 300. The load side terminal 500 is connected to one end of a conductive wire 600, and the other end of the conductive wire 600 extends into the transparent housing 200. The transparent housing 200 is filled with an inert gas, and the transparent housing 200 is fixed on the outer housing 100.

[0049] Specifically, in the normal working state of this embodiment, the load side and the power supply side are conducted through the fuse 300, and the current sequentially passes through the power supply side terminal 400, the fuse 300, the load side terminal 500, and the conductive wire 600 to introduce the current into the transparent housing 200. The transparent housing 200 is filled with an inert gas. According to the glow discharge characteristics of the inert gas, the inert gas will emit a specific color of light, so that the staff can determine whether the fuse is working properly by observing the transparent housing 200.

[0050] Specifically, the outer housing 100 is a sealed housing, which is circular tubular or square tubular.

[0051] Specifically, the transparent housing 200 is fixed at the port of the outer housing 100 near the load side terminal 500.

[0052] Further, the outer housing 100 is circular tubular, the transparent housing 200 is fixed at the port of the outer housing 100 near the load side terminal 500, the transparent housing 200 is circular ring-shaped, is coaxially connected, and the transparent housing 200 is sleeved on the load side terminal 500.

[0053] Specifically, the transparent housing 200 is fixed at one end of the load side. Through the transparent housing 200, the load side and the power supply side of the embodiment of the present application can be distinguished, and it is necessary to distinguish the electrodes for installation during installation.

[0054] Further, both the outer housing 100 and the transparent housing 200 are made of ceramic materials.

[0055] Specifically, the inert gas is one or more of neon, helium, argon, xenon, and krypton.

[0056] Specifically, since the electron energy level structures of each inert gas are different, the photon energies (i.e., wavelengths) released during de-excitation are also different, which means that each inert gas has its unique emission color.

[0057] For example: Neon (Ne) usually emits orange-red light; Helium (He) can emit pink light; Argon (Ar) tends to emit blue-violet light; Xenon (Xe) produces blue to white light; Krypton (Kr) emits purple light.

[0058] As a preferred embodiment, neon or helium is used to fill the transparent housing 200. The voltage required for neon or helium to emit light is relatively small, and the color is more vivid when emitting light, making it easier to visually judge the color.

[0059] Specifically, there is an opening on the transparent housing 200, and the conductive wire 600 extends into the transparent housing 200 through the opening, and a sealing gasket is provided at the opening.

[0060] Specifically, the sealing gasket is used to prevent the leakage of inert gas in the transparent housing 200.

[0061] Specifically, the outer housing 100 is filled with arc extinguishing material.

[0062] Specifically, an arc is a strong discharge phenomenon. When the current suddenly breaks through two contact surfaces, due to the electric field and thermal effects, the gas between the contact points is ionized to form a conductive channel, that is, an arc. The existence of an arc will not only consume electric energy, but also cause damage to electrical equipment, such as ablation of contacts and reduction of equipment life. To improve the arc extinguishing ability and safety, specific filling materials are often used to help quickly extinguish the arc when the current is interrupted. Common filling materials for arc extinguishing include, for example, quartz sand (SiO2), nitrogen or inert gas, etc.

[0063] In some embodiments, quartz sand is used as the arc extinguishing material in the outer housing 100.

[0064] Specifically, the fuse 300 and the conductive wire 600 are one or more of copper wire, silver wire, lead-tin alloy wire, and silver alloy wire.

[0065] Specifically, the main function of the fuse 300 is to melt when the current abnormally increases, thereby protecting the circuit from overload or short circuit damage.

[0066] Specifically, the material of the fuse 300 depends on the design, rated current, and usage scenario of the fuse. Generally, for small current fuses, pure copper wire or pure silver wire, lead-tin alloy is usually used; for large current fuses, silver alloy wire, copper sheet, etc. are usually used.

[0067] As a preferred embodiment, a lead-antimony alloy wire is used as the fuse 300. The lead-antimony alloy wire has stable and reliable performance and a low melting point, and can be used as a carrier for carrying the current of the system circuit.

The load side terminal 500 is connected to one end of the conductive wire 600. The other end of the conductive wire 600 extends into the transparent housing 200. The transparent housing 200 is filled with an inert gas, and the transparent housing 200 is fixed on the housing 100.

[0072] Specifically, the housing 100 is circular tubular or square tubular.

[0073] Further, the housing 100 is circular tubular, and the transparent housing 200 is also circular ring-shaped. The transparent housing 200 is sleeved and fixed on the outer ring of the housing 100.

[0074] Specifically, the transparent housing 200 wraps the entire housing 100, and can more intuitively observe the working state of the embodiment of the present application.

[0075] Further, a load side identifier 700 is provided at the bottom end of the transparent material near the load side.

[0076] Specifically, the load side identifier 700 can be a color mark or a shape mark, which is used to distinguish the load side and the power supply side to avoid errors during installation.

[0077] Specifically, the transparent housing 200 is fixed at the port of the housing 100 near the load side terminal 500.

[0078] Further, the housing 100 is made of ceramic material.

[0079] Specifically, there is an opening on the transparent housing 200. The conductive wire 600 extends into the transparent housing 200 from the opening, and a sealing gasket is arranged at the opening.

[0080] Specifically, the transparent housing 200 is not communicated with the housing 100. The housing 100 is used to fill arc extinguishing material, and the transparent material is used to fill inert gas.
