Description

1360147 IX. Description of the Invention: [Technical Field] The present invention provides an energy-saving and environmentally-friendly explosion-proof fuse and a manufacturing method thereof, and particularly relates to a groove having an angle formed at an opposite end of the pipe body, which prevents the fuse from being instantaneously broken. Explosion-proof function · Another manufacturing method includes: pre-melting in a high-frequency manner at the position of the tin point, so that the welding can be more effectively stabilized. [Prior Art] # Traditional insurance color is generally used in electronic products, through the passing current through the fuse If it is too large, the smelting part will be blown to avoid the danger of overheating and ignition of the circuit. The purpose is to protect people and equipment from damage due to overcurrent or even fire. Moreover, with the current electrical equipment being light and short, the functions are more and more complicated, more and more parts are needed, and the circuit and electronic components on the circuit board are more and more dense, so the circuit of the circuit board tends to be finer. The micro-mining of electronic components has been the normal use method, which can make the parts of the circuit board more dense, so that more functions can be placed on the same area of the printed circuit board. However, the conventional method of manufacturing a fuse is shown in the first figure, which is a schematic diagram of a conventional fuse spring. The solder is soldered by hot air and flame, and the surface of the tin tin liquid is naturally recessed downward so that it cannot directly mate with the manufacturing method of the fuse 200 and the connecting pin 300, and two copper caps must be set at the end. Shed, _, multiple times of tin-melting, and no good positioning design, so that it forms an unstable side. Therefore, its product is not good, manufacturing cost is high, waste materials and energy are used, and the production rate is high. . In addition, the '-domain sub-circuit system places the parts on the circuit board H and puts the jigs on the other side. The solder joints of the processing pins make the fuses and the melting parts easy to occur. Peeling, because the appearance is positive f, it is not easy to check the small peeling of the internal melting part and the pin 6 to produce local isothermal temperature, resulting in secondary refining, so that the maximum rated current is greater than the normal rating, so that it can not be normal rated The maximum current is used, which causes expensive equipment damage, burnt, 5 damage or dangerous accidents, so the protection is not complete and can not meet the market demand. Therefore, the conventional technology has the following disadvantages: 1. Conventional technology fuse Soldering with hot air and fire, the surface of the tin tin bath is naturally recessed downwards, so that it cannot directly conform to the manufacturing method of the fuse and the connecting pin. 2. Conventional technology fuses, when working on the soldering point of the soldering point, are prone to local high temperature, resulting in secondary soldering, incomplete protection, and can not meet the market demand. 3. The traditional technology of the wire is in the end of the two new 姊, many times immersed in tin, the electrical resistance is increased, the manufacturing cost is high, the use of waste materials and energy, high production failure rate. 4. The know-how of the wire can not be used to determine the normal rated maximum (four) flow, protect the circuit safety, and cause expensive equipment damage, burnout, injury or dangerous accidents. In view of this, how to eliminate the above-mentioned defects is the technical difficulty point that the inventor of this case wants to solve. Therefore, the inventor of this case based on years of experience in the design of related products, feels the money of the above-mentioned products, after years of suffering. Jobs, research, trial improvement, and finally can eliminate the many shortcomings of the fuse to successfully develop the case, so that the invention was born, and to enhance the efficacy.
