Abstract

A fusible link unit includes a fusible link main body that includes a bus bar for connecting to a battery terminal, and a battery that has a battery post for connecting to the battery terminal. The fusible link main body includes an L-shaped housing having a first face and a second face which oppose two side surfaces forming a corner portion of the battery. The bus bar is connected to a fuse portion and is extended from the first face of the housing. Abutment portions for abutting against the side surfaces of the battery are provided on the first and second faces of the housing respectively.

Claims

1. A fusible link unit, comprising:

a battery terminal that is connected to a battery post which extends from a first side surface of a battery; and

a fusible link main body having a base portion and a bus bar insert molded in the base portion and electrically connected to the battery terminal,

wherein the base portion has an L-shape having a first face and a second face disposed orthogonal to each other;

wherein the fusible link main body includes a main stud bolt for connection to the battery terminal and at least one auxiliary stud bolt for connection to a wire harness and a fuse portion provided on the bus bar which is electrically connected between the main stud bolt and the auxiliary stud bolt;

wherein said first and second faces respectively include abutment portions which respectively abut against second and third side surfaces of the battery that are orthogonal to each other and to the first side surface during the connection or disconnection of the battery terminal to the main stud bolt or the wire harness to the auxiliary stud bolt; and

wherein the abutment portions are protruding portions which are provided so as to respectively project toward the second and third side surfaces of the battery.

2. The fusible link unit according to claim 1,

wherein the bus bar includes a connection end portion which extends from the first face of the base portion and contacts the battery terminal;

wherein a supporting portion which abuts against the first side surface of the battery is extended from the second face of the base portion; and

wherein the first side surface is an upper surface of the battery.

3. The fusible link unit according to claim 2, wherein the supporting portion is a protruding portion which is provided so as to project toward the upper surface of the battery.

4. The fusible link unit according to claim 1, wherein the wire harness is connected to an electrical equipment circuit.

5. The fusible link unit according to claim 1, wherein the abutment portions are projected in first and second directions which are respectively perpendicular to an extending direction of the battery post.
