Fusible link and method of producing said fusible link
First Claim
1. A fusible link in which a large-current fuse circuit is formed, comprising:
- a plurality of fuse circuit-forming members, each having a plurality of terminal portions which are connected to an interconnecting plate portion through respective fusible portions, and a plurality of insulating housings on which said plurality of fuse circuit-forming members are mounted respectively;
wherein a bending portion is integrally formed between adjacent fuse circuit-forming members of said plurality of fuse circuit-forming members, said bending portion and said adjacent fuse circuit-forming members are formed in a conductive flat plate, said housings are integrated with said circuit forming members by insert-molding, and said bending portion is bent at a predetermined portion therein so that said housings are opposed in parallel with each other.

Abstract
In a fusible link including a plurality of fuse circuit-forming members each having a plurality of terminal portions which are arranged in a chain-like manner, and are connected to an interconnecting plate portion through respective fusible portions, and the plurality of fuse circuit-forming members are mounted on housings to form large-current fuse circuits. A bending portion is formed integrally at a generally central portion of the interconnecting plate portion, and the fuse circuit-forming members are formed integrally respectively at opposite sides of the bending portion, and the bending portion and the fuse circuit-forming members are formed by an electrically-conductive flat plate. The insulating housings are formed integrally respectively on the fuse circuit-forming members by insert molding, and the bending portion is bent at its predetermined portions in such a manner that the housings are disposed in parallel opposed relation to each other.

4. A method of producing a fusible link in which a large current fuse circuit is formed, the fusible link including a plurality of fuse circuit-forming members each having a plurality of terminal portions which are connected to an interconnecting plate portion through respective fusible portions, said plurality of fuse circuit-forming members being mounted on respective insulating housings, the method comprising the steps of:
-
forming a bus bar having the plurality of fuse circuit-forming members and a bending portion integrally formed between adjacent fuse circuit-forming members of said plurality of fuse circuit-forming members by pressing a single conductive flat plate;
integrating insulating housings with said fuse circuit-forming members by insert molding;
provided respectively at the opposite sides of said bending portion of said bus bar;
bending said bending portion at a predetermined portion so that said housings are opposed in parallel with each other; and
engaging a retaining portion formed in one of said two housings with an engagement portion formed in another housing.
