Electrical junction box provided with electric current sensor

摘要

An electric current sensor is disposed in an upper end part of a casing in an electrical junction box. A detecting bus bar penetrates a through-hole in the electric current sensor so that opposite ends of the detecting bus bar project from the through-hole. A bolt hole is provided in an input side portion on one end projecting from the through-hole. Bolt holes are provided in an output side portion on the other end projecting from the through-hole. A bolt hole is provided in an input side bus bar. The input side bus bar is disposed below the input side portion so that the bolt hole is communicated with the bolt hole. Bolt holes are provided in output side bus bars. The output side bus bars are disposed below the output side portion so that the bolt holes are communicated with the bolt holes. Bolts are inserted downward into the communicated bolt holes to secure the electric current sensor to the input and output side bus bars. The electric current sensor can be removed from the input and output side bus bars by releasing the bolts.
