Abstract

A connecting structure of a fuse link 21 and external terminals 22,23 is provided, wherein a terminal connecting nut 27 is screwed to a male threaded portion 26 projecting through a metallic fuse member 25 of the fuse link 21 retained in a setting portion 24 so as to secure the external terminal 22 to the metallic fuse member 25 in a conductive state and a terminal connecting bolt 28 is put through both of the external terminal 23 and the metallic fuse member 25 and is screwed to a female threaded portion 68 so as to secure the external terminal 23 to the metallic fuse member 25 in a conductive state.

Claims

1. A connecting structure of a fuse link and external terminals, comprising:

the fuse link having a metallic fuse member having a fuse portion to be fused by overcurrent for circuit-breaking, a first conductor continuing from one end of the fuse portion, and a second conductor continuing from the other end of the fuse portion;

a setting portion having a first connecting member having a male threaded portion and a second connecting member having a female threaded portion embedded therein so as to retain the fuse link therein; and

at least two external terminals to be connected to the metallic fuse member of the fuse link,

wherein

the male threaded portion is inserted into either one of the first conductor and the second conductor so as to secure at least one of the external terminals thereto by screwing a terminal connecting nut to the male threaded portion

and a terminal connecting bolt is inserted into the other one of the first conductor and the second conductor so as to secure the other of the external terminals thereto by screwing the terminal connecting bolt to the female threaded portion.

2. The connecting structure as set forth in claim 1, wherein

a base portion of the first connecting member and a base portion of the second connecting member are arranged on a substantially same plane.
