Patent ID: 7102483

Claim:
A multi-layer over-current protector to reduce initial resistance, increase peak resistance, and in turn upgrade voltage-withstanding performance comprising: multiple over-current protection devices stacked on one another and segregated by at least one reinforced insulation layer between two abutted over-current protection devices; a conducting mechanism being each provided on both sides of the over-current protection devices at both ends of those over-current protection devices to connect all the over-current protection devices in parallel, both conducting mechanisms constituting the terminal voltage of the entire over-current protector; and a first and a second conducting parts of a first conducting layer and a first and a second conducting parts of a third conducting layer are respectively provided to where each over-current protection device is attached to the reinforced insulation layer, wherein both of the first and the second conducting parts of the first conducting layer as well as the first and the second conducting parts of the third conducting layer do not have any physical contact with both conducting mechanisms on both sides of the over-current protector, a conducting device instead directly connecting the conducting parts of each layer of the over-current protection device, the conducting layers being disposed between the over-current protection devices.
