Abstract

A fuse unit includes a first connection part to which power is fed and a second connection part to be connected with a mating terminal. The second connection part includes a bolt connection portion to which the mating terminal is connected by a bolt and a connecter connection portion to which the mating terminal is connected by a connector.

Claims

1. A fuse unit, comprising:

a first connection part to which power is fed; and

a second connection part configured to be substantially perpendicular extended from the first connection part and being connected with a mating terminal, the second connection part including;

a bolt connection portion to which the mating terminal is connected by a bolt; and

a connector connection portion to which the mating terminal is connected by a connector;

wherein the bolt connection portion is formed with a bolt insertion hole,

the connector connection portion is a tab terminal, and

the bolt insertion hole is formed in the bolt connection portion such that an axis of a stud bolt to be inserted into the bolt insertion hole is perpendicular to a plane of a substantially planar part of the tab terminal.

2. The fuse unit according to claim 1, wherein

the bolt connection portion and the connector connection portion are provided in a busbar,

an insulating resin part is provided around the busbar,

a stud bolt which is inserted into the bolt insertion hole is fixed by the insulating resin part,

the connector connection portion is a tab terminal formed by a part of the busbar, and

a connector housing is formed at periphery of the tab terminal by the insulating resin part.

3. The fuse unit according to claim 2, wherein

a screw of the stud bolt projects at a side which the connector housing projects with respect to the connector connection portion.

4. The fuse unit according to claim 2, wherein

a screw of the stud bolt projects at a side opposite to a side which the connector housing projects with respect to the connector connection portion.

5. The fuse unit according to claim 1, wherein

the bolt connection portion and the connector connection portion are provided in a busbar,

an insulating resin part is provided around the busbar,

the connector connection portion is a tab terminal formed by a part of the busbar, and

a connector housing is formed at periphery of the tab terminal by the insulating resin part.

6. The fuse unit according to claim 1, wherein

the bolt insertion hole is formed in the bolt connection portion such that the axis of the stud bolt to be inserted into the bolt insertion hole is perpendicular to an axis of a bolt to be inserted into a bolt insertion hole formed in the first connection part.
