Assembling structure of current detection apparatus

摘要

An assembling structure of a current detection apparatus includes: a bus bar; a sensor main body having a magnetism detection element which detects a magnetism generated from the bus bar; a housing having a sensor compartment which accommodates the sensor main body; a magnetism shield member mounted externally on the housing; a cover that holds the bus bar and the magnetism shield member by the at least part of the upper surface of the cover and the lower surface of the housing therebetween; a projecting portion formed on the cover, which projects upwards from the upper surface of the cover; a hole formed in the bus bar, through which the projecting portion of the cover is inserted; and a hole formed in the lower surface of the housing, which is adapted to fit on the projecting portion which passes through the hole in the bus bar.
