WIRE CONNECTION TYPE POWER DISTRIBUTION APPARATUS

PROBLEM TO BE SOLVED: To provide a power distribution apparatus having a wire insertion port for easily inserting and positioning a wire to a wire storage hole of a terminal metal fitting, with excellent workability of wiring work, without increasing a size.SOLUTION: A wire insertion port 12b is for leading an inserted wire 15 to a wire storage hole 13a of a terminal metal fitting 13. The wire 15 is configured by binding a plurality of element wires 15a. The wire 15 inserted to the wire insertion port 12b is electrically connected to the terminal metal fitting 13 by storing the distal end part of the wire in the wire storage hole 13a and fastening it with a terminal screw 14. The wire insertion port 12b has a vertical cross sectional shape in a shape of an arc 21a of a circle 21 for which a wire insertion end side is opened widely and the side of the terminal metal fitting 13 is narrowed and connected to the wire storage hole 13a. A diameter of the wire insertion port 12b opened on the side of the terminal metal fitting 13 is reduced to be about the same as the diameter of an entrance of the wire storage hole 13a.
