Complex type fusible link, fuse box, and manufacturing method thereof
View Patent ↗The present invention provides a complex type fusible link which includes an insulative block base including a plurality of cavities; a conductive connecting plate which is integrally embedded in the insulative block base, a part of the conductive connecting plate being exposed to at least one of the cavities; a plurality of fusible elements each of which is accommodated in corresponding one of the cavities and includes a first end which is connected to the part of the conductive connecting plate and a second end; and a plurality of terminals each of which is integrally embedded in the insulative block base and includes a first end which is connected to the second end of corresponding one of the fusible elements and a second end which is exposed from the insulative block base.
1. A complex type fusible link comprising:
an insulative block base including a plurality of cavities;
a conductive connecting plate which is integrally embedded in the insulative block base, a part of the conductive connecting plate being exposed to at least one of the cavities;
a plurality of fusible elements each of which is accommodated in corresponding one of the cavities and includes a first end which is connected to the part of the conductive connecting plate and a second end; and
a plurality of terminals each of which is integrally embedded in the insulative block base and includes a first end which is connected to the second end of corresponding one of the fusible elements and a second end which is exposed from the insulative block base, wherein the first and the second end of at least one of the fusible elements are spaced from each other in a direction perpendicular to a surface of the conductive connecting plate, and
said at least one of the fusible elements includes two joint portions formed respectively at the first and second ends of said at least one of the fusible elements and an intermediate fusible portion interconnecting the two joint portions, wherein the intermediate fusible portion is inclined in a thickness direction of said at least one of the fusible elements at a given angle with respect to the two joint portions.
2. A fuse box comprising:
a complex type fusible link comprising:
an insulative block base including a plurality of cavities;
a conductive connecting plate which is integrally embedded in the insulative block base, a part of the conductive connecting plate being exposed to at least one of the cavities;
a plurality of fusible elements each of which is accommodated in corresponding one of the cavities and includes a first end which is connected to the part of the conductive connecting plate and a second end;
a plurality of terminals each of which is integrally embedded in the insulative block base and includes a first end which is connected to the second end of corresponding one of the fusible elements and a second end which is exposed from the insulative block base, wherein the first and the second end of at least one of the fusible elements are spaced from each other in a direction perpendicular to the conductive connecting plate; and
a transparent cover which covers the complex fusible link from outside thereof,
wherein said at least one of the fusible elements includes two joint portions formed respectively at the first and second ends of said at least one of the fusible elements and an intermediate fusible portion interconnecting the two joint portions, wherein the intermediate fusible portion is inclined in a thickness direction of said at least one of the fusible elements at a given angle with respect to the two joint portions.
