Taking the bus wire row as an example, the assembly process of the wire row and the interlock contactor 1 body is specifically described. When the bus wire row needs to be assembled with the interlock contactor 1, the detachable terminal block 2 on the interlock contactor 1 is first removed, and the first connecting pin 411, the second connecting pin 412, the third connecting pin 421, the fourth connecting pin 422, the fifth connecting pin 431 and the sixth connecting pin 432 of the conductive row of the bus wire row are placed on the contact plate 5 of the interlock contactor 1.
