Precision Requirements For Fuse Dimensions In Manufacturing And Assembly

The specifications for the length of the fusible tube and the dimensions of the contact slot not only involve the external dimensions themselves, but also relate to the positioning of drop out fuse during the installation process. Tubular fuses typically use standardized dimensions, such as 5×15mm and 6.3×32mm, which are designed with the interface between the fuse tube, contact terminals, and slot in mind. Since the slot dimensions do not deviate significantly in mass production equipment, controlling the fuse tube length error to within ±2mm is crucial for maintaining consistency across all specifications and ensuring a gapless or minimal-gap fit on the production assembly line.
