Wherein the plurality of terminals of the terminal block and the circuit board are electrically connected via a plurality of wires for supplying power or transmitting input and output signals, and the plurality of terminals of the terminal block are electrically connected via external equipment and a connecting wire. That is, the terminal block is an intermediate connection medium for electrically connecting an external device and the printed circuit board.

As shown in fig. 1, in the conventional terminal block 10, the terminal 11 is bent four times to form a downward zigzag-type insertion protrusion 12, and is combined with the terminal block 10 formed with the upper and

lower insertion grooves

13, 14 by punching. In addition, the terminal 11 is difficult to process, and the amount of metal required to manufacture the terminal 11 is increased, resulting in an increase in manufacturing costs, and since a separate device is also required to be coupled to the terminal block 10, there is a problem in that it is difficult to separate it when it must be disassembled later for maintenance or repair.

In addition, in the conventional terminal block 10, since the bolt coupling holes 15 are formed to protrude laterally on both sides and are fixed by bolts inside the housing case 20, an additional tool and bolt are required for mounting, which is laborious and time-consuming.
