InactiveUS20080191832A1Ensure long-term reliabilityLow costFuse device manufactureElectrical and Electronics engineeringFuse cutout
A chip-type fuse is based on an electrically insulating substrate and fusible element is disposed thereon. A protective layer is formed over the fusible element and adheres to the substrate around the fusible element so as to define a cavity between the protective layer and the fusible element. The cavity isolates the protective layer from direct contact with the fusible element so that the protective layer will not be melted or breached by the excessive heat and arc generated by the fusible element under overload condition. Further, the cavity can be hermetically sealed to enclose a gas of pressure less than one atmosphere. A thermally insulating layer and an arc suppressive layer may be incorporated to reduce the response time and arc intensity of the chip-type fuse respectively under overload condition. The method of manufacturing chip-type fuse, particularly the method of forming fusible element and cavity, is described too.
