Method of manufacturing a complex fusible link
View Patent ↗A manufacturing method of a complex type fusible link. The manufacturing method includes hollowing out a metal plate into a link-like conductor including a connecting plate and a terminal, cutting out the link-like conductor so as to separate the connecting plate and the terminal, forming, by insert molding, a block base including a cavity after setting the connecting plate and the terminal in a mold, and directly connecting a fusible element to an exposed portion of the connecting plate and an exposed portion of the terminal.
1. A manufacturing method of a complex type fusible link comprising:
hollowing out a metal plate into a link-like conductor including a connecting plate and a terminal;
cutting out the link-like conductor so as to separate the connecting plate from the terminal;
forming, by insert molding and after setting the cut out connecting plate and the cut out terminal in a mold, a block base including a cavity; and
directly connecting a fusible element to an exposed portion of the connecting plate and an exposed portion of the terminal.
2. The manufacturing method of claim 1 , wherein the connecting plate is separated from the terminal with one cut.
3. The manufacturing method of claim 1 , wherein the connecting plate is shaped differently from the terminal.
4. The manufacturing method of claim 1 , wherein the connecting plate is laterally offset from the terminal.
5. The manufacturing method of claim 1 , wherein the fusible element includes a first joint portion connected with the terminal and a second joint portion connected with the connecting plate, and the fusible element is inclined such that the first joint portion and the second joint portion have different heights.
6. The manufacturing method of claim 1 , wherein the fusible element includes a first joint portion connected with the terminal, a second joint portion connected with the connecting plate, and a central portion inclined relative to the first joint portion and the second joint portion.
7. A manufacturing method of a complex type fusible link comprising:
a hollowing process to hollow out a metal plate into a link-like conductor including a connecting plate and a plurality of terminals connected via the connecting plate;
a cutting out process to cut out the link-like conductor so as to separate the connecting plate from the terminals;
an insert molding process to form a block base including a cavity after setting the cut out connecting plate and the cut out terminal in a mold, wherein the terminals and at least a part of the connecting plate are disposed within the block base; and
a connecting process to electrically connect a fusible element to the cavity.
