Fuse Board Bent Wiring Pattern Vibration Absorption

The patent replaces the wire-bonding mechanical process with a bracket welding process. Instead of bonding wire to electrode terminals, a metal plate with integrated fuse portions is welded directly to the electrode plate, eliminating the wire-bonding step and its associated complexity while improving bonding strength through direct welding connection.

The patent merges the fuse structure with the metal plate by forming fuse portions directly on the metal plate through punching and bending. This integration eliminates separate wire components and bonding steps, simplifying manufacturing while ensuring strong mechanical and electrical connection between the fuse and electrode plate.

The patent introduces bent portions with curved wiring patterns in the fuse portions instead of straight wires. These bent portions act as vibration absorbers, reducing stress concentration and preventing wire cutting during welding and operation, while maintaining manufacturing simplicity through standard punching and bending processes.

The bent portions are pre-formed in the metal plate during manufacturing to provide vibration absorption and stress relief before the welding process. This beforehand cushioning prevents wire cutting during welding and operation without requiring additional manufacturing steps or bulkier wire designs.

The patent incorporates bent portions with curved wiring patterns formed through punching and bending processes. These curved portions absorb vibration and reduce stress on the fuse wire, preventing cutting during welding and operation while maintaining the simplicity of the punching and bending manufacturing process.

The patent changes the geometric parameters of the fuse portions by introducing bent portions with specific curvature radii and angles. This parameter modification allows the fuse board to withstand vibration and welding stresses without wire cutting, while still being manufacturable through standard punching and bending processes.
