Abstract

The invention discloses a fuse which comprises a main body, a safety wire and a fixed sealing assembly. The main body is a tubular structure with two open ends and is provided with a quartz sand layer inside. The safety wire stretches into the main body, with both ends extending out of the main body and then bending at the outside. The fixed sealing assembly is composed of a fixed gasket and a sealing cap; the fixed gasket is arranged at two ends of the main body and rests against the two ends of the main body, and the sealing cap is fixedly hitched at two ends of the main body, respectively resting against the fixed gasket and the safety wire. The invention further discloses a fuse installation method. The fuse and the installation method are simple and convenient; the fuse is reliable in performance and resurfacing welding is not required during the installation, thus avoiding overflow of the solder and fault soldered joint and preventing the safety fuse from being broken by compression; therefore good contact between the safety wire and the sealing cap and the integrity of the product can be ensured, thus improving qualification rate and economic benefits.

Description

technical field

[0001] The invention relates to a line protection device in electric and electronic equipment, and more specifically relates to a fuse and an assembly method thereof, which can prevent the two ends of the fuse from being broken by pressure. Background technique

[0002] At present, due to its simple structure, convenient use, and low cost, fuses have been widely used in various electronic and electrical fields including instrumentation, industrial control, test and measurement, various household appliances, audio-visual equipment, and residential power supply equipment. At present, the fuses of many fuses are connected by overlay welding, but during overlay welding, solder overflow and false welding of the fuse are prone to occur, which seriously affects the appearance, quality and performance of the product. see figure 1 As shown, a common small fuse 10 includes a body 11, a fuse 12 and a sealing cap 13, the body 11 is a tubular structure, the fuse 12 is ar...
