Abstract

An electric junction box including a case, an input bus bar, an output bus bar and a fuse which are accommodated within the case, wherein an input electric wire and an output electric wire are electrically connected to the input bus bar and the output bus bar, respectively, the electric junction box further including an input-side fastening member which fastens an input terminal of the fuse and the input bus bar to the case in such a state that the input terminal is laid to overlap the input bus bar, and an output-side fastening member which fastens an output terminal of the fuse and the output bus bar to the case in such a state that the output terminal is laid to overlap the output bus bar, wherein the input-side fastening member and the output-side fastening member are conductive and are passed through the case, and a connecting terminal of the input electric wire is fastened to the case at a distal end portion of the input-side fastening member which is exposed from the case, and a connecting terminal of the output electric wire is fastened to the case at a distal end portion of the output-side fastening member which is exposed from the case.

Claims

1. An electric junction box comprising:

a case;

an input bus bar and an output bus bar which are accommodated within the case; and

a fuse accommodated within the case such as to bridge the input bus bar and the output bus bar, wherein an input electric wire and an output electric wire are electrically connected to the input bus bar and the output bus bar, respectively;

an input-side fastening member which fastens an input terminal of the fuse and the input bus bar to the case such that the input terminal is laid to overlap the input bus bar; and

an output-side fastening member which fastens an output terminal of the fuse and the output bus bar to the case such that the output terminal is laid to overlap the output bus bar,

wherein the input-side fastening member and the output-side fastening member are conductive and are passed through the case, and

a connecting terminal of the input electric wire is fastened to the case at a distal end portion of the input-side fastening member which is exposed from the case, and a connecting terminal of the output electric wire is fastened to the case at a distal end portion of the output-side fastening member which is exposed from the case.
