Abstract

A fusible link unit having a fuse circuit structure containing a plurality of female terminal parts linked through fusible members to a linking plate and screw fixing terminal parts, which are connected to the fuse circuit structure in a chain manner, and a housing into which the fuse circuit structure is assembled, is disclosed. In the fusible link unit, the fuse circuit structure is formed by laminating a plurality of part plates, and the part plates include linking portions corresponding to the linking plates, and the female terminal parts with the fusible members connected thereto and the screw fixing terminal parts, which are shared by the part plates.

Claims

1. A fusible link unit comprising:

a fuse circuit structure including a plurality of terminal parts linked through fusible members to a linking plate, and

a housing into which the fuse circuit structure is assembled,

wherein the fuse circuit structure is formed by laminating a plurality of part plates,

a first part plate includes a first linking portion constituting the linking plate by being laminted by a second linking portion of a second part plate, and

a respective part of the plurality of terminal parts which are connected to the linking plate with a respecitve part of the fusible members are provided with the first part plate.

2. A fusible link unit according to claim 1, wherein the first part plate and the second part plate have substantially identical number of the terminal parts to each other.

3. A fusible link unit according to claim 1, wherein the number of the part plates is two.
