On the other hand, like the first electrode 144, the second electrode 145 includes four protrusions 145a at each end, but the bent portion 144b does not exist. This is because the bent portion 144b is formed not to be in contact with each other when the first electrode 144 and the second electrode 145 cross each other, due to the bent portion 144b of the first electrode 144. This is because the second electrodes 145 can be arranged as they are without being bent.

However, both the first electrode 144 and the second electrode 145 may be bent to avoid contact between the two electrodes 144 and 145 intersecting on the base 141.

When the ends of the wire 10 are inserted into the grooves 142a, the first electrode 144 and the second electrode 145 press the energization block 143 to hold and hold the wire 10 and fix the connected wire with the same polarity. Energize.

As a result, when one wire 10 flowing from the outside is connected to one surface of the connector 140 for distribution, electricity can be supplied to each generation while distributing the wires connected to the remaining three surfaces.

A cover 146 may be further included to collectively fix the electrodes 144 and 145. Therefore, the base 141 is provided with a fixing part 147 to cover the cover 146 while pressing the electrodes (144, 145).

According to the present invention as described above, while minimizing the number of wires embedded in the cement mortar to prevent the weakening of the cement mortar durability, while minimizing the risk of short-circuit and short-circuit, while ensuring a robust and safe distribution, In order to increase the durability of the cement mortar further includes a fastening member that mediates the coupling with the reinforcement is reinforced, there is an effect to enable a solid installation of the wire terminal box.
