Abstract

The invention discloses a fuse, which comprises metal casings, lead-antimony alloy strips are installed between two sets of metal casings, sodium strips are arranged above and below the lead-antimony alloy strips, and the lead-antimony alloy strips The outer side of the bar and the sodium bar is covered with an insulating sleeve. hole. The structure of the present invention is simple and novel. Compared with traditional fuses using lead-antimony alloy as the fuse body, the invention has good sensitivity, and the fuse body has a fast fusing speed. and blade-shaped joints are respectively inserted into the two ends of the opening slot, and the gaps are welded respectively; the insulating sleeve and the metal casing adopt an interference fit, so that both ends of the insulating sleeve are interference-fit and plugged into the inner side of the metal casing, so that The overall fixing of the fuse is more firm.

Description

technical field [0001] The invention relates to the technical field of fuses, in particular to a fuse and a manufacturing method thereof. Background technique [0002] With the development of the electronic industry, the requirements for miniaturization and integration of components in the field of electronic products are getting higher and higher, and the volume of chip protection components is also greatly reduced. For example, a PCB base fuse with application number CN201710815001.5 includes a PCB substrate, two terminal electrodes and a melt layer, the two terminal electrodes are respectively coated on both ends of the PCB substrate, and the melt layer is arranged on The upper surface of the PCB substrate and the two ends of the melt layer are respectively connected to two terminal electrodes; the PCB substrate is also attached with a substrate coating layer at least on the upper surface, and the substrate coating layer is made of flame-retardant arc-extinguishing glue; ...
