Patent ID: 8258913

Claim:
A fuse element, comprising: a first conductive part and a second conductive part; and a fusible body which electrically connects the first conductive part and the second conductive part, and is adapted to fuse when an overcurrent flows therethrough; wherein the fusible body is formed in a plate shape; wherein the fusible body has a first connection portion, a second connection portion and a fusing member adapted to fuse when the overcurrent flows therethrough, a first end and a second end of the fusing member being connected to the first connection portion and the second connection portion respectively; wherein the first connection portion and the second connection portion form a common plane; and wherein a central material of the fusing member is displaced perpendicularly away from the common plane while maintaining a thickness of the fusing member before and after the displacement, thus forming a first and a second displacement defined by a distance between the first and second ends of the fusing member and the common plane, respectively; wherein cross-sectional contact areas of the first and second ends respectively connected to the first and second connection portions are reduced as a result of displacing the fusing member, thereby increasing the electrical resistance at the first and second ends relative to the first and second connection portions by a predetermined amount.
