[Challenges devised to solve the above before described in the prior art
Our branch box has a simple structure in which it is attached to a utility pole at the back, and a box that opens only the front door has a main line introduction terminal and a branch line terminal.The main line connection is functional inside the box. It has a screw tightening structure that does not consider attachment and detachment, and the number of connection terminals of the internal branch line is only on one side, so the number is small, and various types of connections such as thin wire, medium thick line, thick line with capacity according to customers are supported Is difficult . In addition, the latter branch branch box is a branch / retract method.
However, the composite branch line is provided only on the front door side,
Branch wires are bundled in advance and screw terminals are provided at the top.
Since it is a composite branch line, it can respond to changes in customer demand.
On the other hand, there are inconveniences such as difficulty in connecting branch lines.

[0004] The door of the box has a problem such as awkward connection work such as connecting lines in the shaft side because you can not move in a fixed support shaft, Toka structure to remove the door of the branch lead-box, single swing in the door Ru More others openable to either side provided on both sides of the support shaft to be inserted or removed but there is a risk of treatment is inconvenient drop in altitude of the utility pole, and also connected at the time of connection work of the branch line
Other phases may be covered with an insulating sheet to prevent contact with tools or the human body, but this is inconvenient for work.
It was

The present invention solves such conventional problems
The main line can be connected by selecting the main line terminal rows on the front and rear sides of the insulating lid, depending on the installation position of the transformer.
In addition, a large number of electric wires of the capacity and quantity according to the customer can be connected to the branch line connection fittings attached to the front and rear surfaces of the terminal board inside the box,
In addition, the connection work is convenient, and the shielding plate and the protection plate
In order to ensure work safety, and when replacing an existing transformer, connect the trunk line of another transformer to the unused terminal line for the main line provided on the cover to put it in an uninterrupted state. It is an object of the present invention to provide a power distribution branch box in which an existing transformer can be replaced, repaired, etc., and an opening / closing door can be folded to allow left and right movement to facilitate electric wire connection work.
