The welding step (S120) is a process step of manufacturing a connection portion (501) formed by welding an interface between the metal plates accommodated in the arranging step (S110) and made of different metal materials on both sides.

The forming step S130 is a step of machining a metal plate made of any one of the metal materials forming the connecting portion 501 generated by the welding step S120 to form a body 533 composed of a plate portion 533 and an inserting portion 535 503).

The first installation step S140 is a process step of coupling a metal layer of the same material as the metal material of the planar electrical connector 400 among the metal layers 511 and 513 of the connection portion 501 to the planar electrical connector 400 .

The second installation step S150 is to connect the plate portion 531 of the body 503 of the same material as the non-contact metal layer which is the unbonded metal layer of the connection portion 501 coupled to the planar electrical connector 400 by the first installation step S140 ) To the non-contact metal layer of the connecting portion 501. [

The third installation step S160 is a step of inserting a cable into the insertion hole 533 of the insertion portion 531 of the body 503 coupled to the connection portion 501 by the second installation step S150 .

As described above, the dissimilar metal connection apparatus 500 according to the second embodiment of the present invention can be selectively installed according to the metal material of the electrical connector to be connected, and the connection unit 501, The metal body 503, which is the same as the non-contact metal layer of the non-contact metal layer, is connected to the connecting portion 501, so that the dissimilar metal can be electrically connected by a simple method.

Further, since the dissimilar metal connection apparatus 500 is configured to selectively install the body and the connection portion corresponding to the metal material of the electrical connector and the cable when the connection and the body are manufactured, the manufacturing and installation process is simple and easy But the explosion welding process as in the prior art (100) can be omitted, which can significantly reduce the manufacturing cost and time.

Also, the heterogeneous metal connection device 500 can increase the throughput by minimizing the loss of material.

In addition, the dissimilar metal connection device 500 is constructed such that the contact layer and the body of the connection part are made of different metal materials, thereby effectively preventing the electrochemical reaction between the dissimilar metals.
