Problems solved by technology

At the same time, limited by the miniaturization trend of modern electronic equipment, the maximum size of the miniature fuse shall not be larger than the 4012 size specified by the IEC standard
The fuses in the prior art use tin-clad copper winding fuses and a large amount of high-temperature solder. When breaking, all the melt and a large amount of solder will be melted and gasified to generate huge pressure, which will cause the fuse to catch fire and explode. Meet the requirements for safe use

Abstract

The invention discloses a mini super surface-mounted fuse protector. The mini super surface-mounted fuse protector comprises a melt, at least two cavity plates, at least two substrates, end electrodesand fillers. The melt is provided with a low-overload striking point and at least two high-interruption striking points. The high-interruption striking points are connected with the low-overload striking point in series, and are arranged on two sides of the low-overload striking point. The cavity plates are provided with cavities. The substrates are stacked on the upper side and the lower side ofeach cavity plate. The end electrodes are electrically connected with the melt, and are arranged on the substrates and / or the cavity plates. The cavities are filled with the fillers, namely powder materials in different sizes. The low-overload striking point and the high-interruption striking points are located at corresponding positions of the cavities. The invention further provides a manufacture method of the surface-mounted fuse protector. The mini super surface-mounted fuse protector has the advantages that consumer electronic circuits for civil use can be protected under various overload conditions, and hidden danger such as shell smoking, crack or explosion is avoided.

Description

technical field [0001] The invention relates to the field of electronic protection components, and in particular provides a miniature super surface mount fuse and a manufacturing method thereof. Background technique [0002] With the development of modern electronic technology, portable modern electronic devices have entered thousands of households from mobile phones, notebook computers to tablet computers. Prepare weapons. Recently, major safety accidents such as battery explosion, charging overheating, charger smoke and fire or even fire have occurred frequently, and the requirements for safety design specifications of batteries and chargers are getting higher and higher. As a secondary protection component, how to play a safe and reliable protective role in electronic circuits is closely related to the characteristics of the fuse. There are three main types of traditional fuses used to protect the AC input of chargers: [0003] 1) Miniature fuse with plastic shell pins...
