Patent ID: 8237435

Claim:
An assembling structure of a current detection apparatus comprising: a bus bar; a sensor main body having a magnetism detection element which detects a magnetism generated from the bus bar and adapted to calculate a value of a current which flows through the bus bar based on the detected magnetism; a housing having a sensor compartment which accommodates the sensor main body, wherein a lower surface of the housing faces one of surfaces of the bus bar; a magnetism shield member mounted externally on the housing so that the sensor main body and the bus bar are positioned in an interior of the magnetism shield member; a cover at least part of an upper surface of which faces the other surface of the bus bar, so as to hold 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 when the bus bar and the magnetism shield member are held by the at least part of the upper surface of the cover and the lower surface of the housing; 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 when the bus bar and the magnetism shield member are held by the at least part of the upper surface of the cover and the lower house of the housing.
