Abstract
An electrical junction box including a casing assembly including an upper casing and a lower casing, a laminated body contained in the casing assembly and layering bus bars and insulation plates alternately, and an electrical current sensor attached to a predetermined bus bar. The predetermined bus bar out of the bus bars is divided into a first bus bar member that passes a through-hole in the electrical current sensor and a second bus bar member to be connected to the first bus bar member by a bolt B and a nut N after the first bus bar member passes the through-hole. A nut-receiving recess for the nut N is provided on a bottom side of the lowermost insulation plate of the laminated body. The lower casing is provided with an attachment hole for the bolt. The bolt passes upward through the attachment hole and passes connecting portions of the first and second bus bars and is fastened and secured to the connecting portions by the nut. This structure reduces the risk of contact between the head of a bolt for fastening a bus bar that passes an electrical current sensor contained in a casing assembly of an electrical junction box and a bus bar constituting a laminated body.
