Abstract

A fuse unit is provided having a fuse element (2) in which a first terminal connecting part (4) and second terminal connecting parts (5) are formed and an insulative resin part (20) is formed on the outer surface of the fuse element (2) with insertion molding. Threaded bolt holes (10) are formed in the first terminal connecting part (4) and the second terminal connecting parts (5) of the fuse element (2). Bolts (30) are temporarily fixed to the fuse element (2) by being screwed into the threaded bolt holes (10), and the insulating resin part (20) is formed with insertion molding by using the fuse element (2) to which the bolts (30) are temporarily fixed as an inserted component.

Claims

1. A fuse unit comprising:

a fuse element;

a terminal connecting part formed as one-piece with the fuse element; and

an insulative resin part which is arranged on an outer surface of the fuse element,

wherein a temporary bolt fixing part, which temporarily fixes a bolt to the terminal connecting part, is provided in the fuse element,

wherein the temporary bolt fixing part is a threaded bolt hole which is provided in the terminal connecting part, wherein the threaded bolt hole is threaded to temporarily fix the bolt when the bolt is screwed into the threaded bolt hole, and

wherein the insulative resin part is inserted-molded with the fuse element and the bolt screwed into the threaded bolt hole being inserted components such that a head of the bolt is embedded in the insulative resin part.

2. The fuse unit according to claim 1, wherein the temporary bolt fixing part temporarily fixes the bolt to the terminal connecting part before an injection molding of the insulative resin part.
