The demand for the use of small fuses in the market is increasing. Small fuses have smaller internal resistance, more diverse fusing characteristics, stronger breaking ability, recoverable, and multiple line arrays, intelligent functions, and multifunctional integrated components or modules, which can be used for overload protection in many products to meet the diverse circuit protection needs of terminal products. Especially small patch fuses, as a new type of component, are suitable for various electronic products with compact structure and small volume. Based on current data, the application fields of small fuses include: 1. Communication field Overpower protection for mobile phone chargers, switching power supplies, LCD screens, as well as routers, modems, network cards, etc. around the network. 2. Computer field Computer motherboards, hard drives, and various components require the use of small fuses, especially disposable and recoverable fuses. They are widely used in off
We know that self restoring fuses are made of special materials, which have the advantages of being able to be used multiple times and automatically recovering after overload actions. Compared to ordinary disposable fuses, self restoring fuses are more commonly used in certain products and do not require frequent replacement. Some people may have some doubts, but what is the appropriate purchase price for self restoring fuses? What is the price for purchasing a fuse? Here, the editor tells everyone that there are both high and low prices for self recovery fuses. According to my investigation, there are currently 0.1-2 yuan range available on the market, and the prices vary from manufacturer to platform. Some manufacturers require lower prices for fuses, but it is difficult to find them. Sometimes, the fuse model you need is less used by others, and the manufacturer produces less, resulting in higher prices. Many manufacturers of electronic products, machinery, and other products
1、 Development History of Fuses In the 1880s, since Edison invented the light bulb and failed countless experiments on tungsten wire, it also opened up the development history of fuses. The success of light bulbs has also driven the development of fuses. With the development of society and the increasing strength of electrical appliances, the fuse industry has also experienced rapid development. The fuse industry in China started relatively late, but has developed rapidly. In 1950, China began to imitate the production methods of the Soviet Union to produce fuses, so the variety of fuses was relatively few, the structure was relatively simple, and the experimental methods were relatively backward. In the early days, the quality of fuses in China was not very good. Until the late 1970s, the emergence of color televisions promoted the development of the fuse industry, and the delay fuses used in color televisions began to move towards international standards. At this time, the fuse
In fact, this is not the case. Although patch fuses have a wider range of applications than plug-in fuses, there is also a high demand for plug-in fuses in the market. Both types of fuses, patch and plug-in, have their own advantages. For different products, selecting the right one can maximize the effectiveness of the fuse. Currently, plug-in fuses will not be eliminated. Taking self recovery fuses as an example, the volume of patch based self recovery fuses is different from that of plug-in based self recovery fuses. Plug-in type fuses have a relatively larger volume and are generally used in circuits with low working voltage and high working current, such as power converters, motorcycles, automobiles, computer power supplies, micro motors, computer interfaces, CPUs, and other fields. And patch type fuses are mostly used in many electronic products and in many circuit boards such as mechanical equipment. With the development and progress of technology, fuses are not only limite
According to different usage requirements, fuse tubes can be divided into two types in structure: lead-free fuse tubes and lead-welded fuse tubes. As shown in the figure, lead-free fuse tubes usually need to be used in conjunction with corresponding fuse holders for easy replacement; Lead soldered fuse tubes can be directly soldered onto printed circuit boards or other circuit components, reducing the spatial position of the circuit. The fuse tube can be divided into a glass shell and a hard shell. According to the different melting times, it can be further divided into ordinary fuse tubes, fast melting fuse tubes, and delayed melting fuse tubes. The fusing time of ordinary fuse tubes is relatively slow, but they are inexpensive and can be applied to overcurrent protection circuits with generally low requirements. The biggest characteristic of fast fuse tubes is their short fusing time, which is suitable for situations that require quick circuit disconnection. The delayed fuse tu
The operating principle of a self restoring fuse tube is a dynamic balance of energy. The current flowing through the components of the self restoring fuse tube series generates heat due to the relationship between the self restoring fuse tube series. The heat generated is completely or partially dissipated into the environment, while the heat not dissipated will increase the temperature of the components of the self restoring fuse tube series. The temperature during normal operation is relatively low, and the heat generated and dissipated reaches a balance. The self-healing fuse series components are in a low resistance state, and the self-healing fuse series does not operate. When the current flowing through the self-healing fuse series components increases or the ambient temperature increases, but if the balance between the generated heat and the emitted heat is reached, the self-healing fuse series still does not operate. When the current or ambient temperature increases again
