Abstract

A fuse unit includes: a fuse element with an insertion hole into which a stud bolt inserted, the stud bolt protrudingly provided on a battery terminal fixed to a battery post protrudingly provided on an upper surface of a battery; and a resin body integrally formed with the fuse element by insert molding, and having an abutment portion abutting on a side surface of the battery. For a plurality of batteries each having the battery post at a different arrangement position, the insertion hole of the fuse element is formed in a shape allowing insertion of the stud bolt thereinto in a state where the side surface of the battery and the abutment portion of the resin body abut on each other.

Claims

1. A fuse unit comprising:

a fuse element including an insertion hole into which a stud bolt is inserted, the stud bolt protrudingly provided on a battery terminal fixed to a battery post protrudingly provided on an upper surface of a battery; and

a resin body integrally formed with the fuse element by insert molding, and including an abutment portion abutting on a side surface of the battery,

wherein, for a plurality of batteries each having the battery post at a different arrangement position, the insertion hole of the fuse element is formed in a shape allowing insertion of the stud bolt thereinto in a state where the side surface of the battery and the abutment portion of the resin body abut on each other.

2. The fuse unit according to claim 1, wherein the insertion hole of the fuse element is formed in an oblong hole shape extending in an abutting direction between the side surface of the battery and the abutment portion of the resin body.

3. The fuse unit according to claim 1, wherein a tapered surface that slides with respect to an upper surface end portion of the battery is formed at an end portion of the abutment portion of the resin body, when the resin body is assembled to the battery.

4. The fuse unit according to claim 2, wherein a tapered surface that slides with respect to an upper surface end portion of the battery is formed at an end portion of the abutment portion of the resin body, when the resin body is assembled to the battery.
