BRANCH BUSBAR ASSEMBLY FOR DISTRIBUTION BOARD

摘要

In the present invention, in order to easily and stably connect the branch bus bar to the bus bus bar, a plurality of slots into which bus bus bars supplying power to each phase are inserted at regular intervals up and down on one side are formed, and through holes and cooling are provided on the opposite side. For this purpose, an air vent for discharging the inside air or introducing outside air is formed, and an insulation case with bolt inserts vertically formed therein, is mounted inside the insulation case, and one end thereof is exposed to the upper surface of one of the slots. A branch bus bar in contact with the upper surface of the bus bar, the opposite end is exposed through the through hole, and a first clearance hole is drilled in the middle, is mounted inside the insulating case, and one end is one of the slots. A clamping jaw exposed on one lower surface facing the branch busbar and elastically deformed by elastic deformation with the lower surface of the bus bus bar, and a screw hole formed at the opposite end thereof, and a screw hole of the clamping jaw through the bolt insertion portion Disclosed is a branch assembly for a distribution board including a tightening bolt that is inserted into the insulating case in a state of being screwed with and tightens the clamping jaw to pressurize and adhere to the lower surface of the bus bar.
