The invention provides an expansion joint of contact rails and belongs to the technical field of rail transit. The expansion joint solves the problem that an existing expansion joint of contact rails is complex in structure. The expansion joint of the contact rails comprises two long-strip-shaped connecting blocks arranged in two side containing grooves of the contact rails respectively, the connecting blocks and the containing grooves are matched in shape, the two sections of contact rails are connected through the connecting blocks, and joints of the two connecting blocks and the two sections of contact rails are each compressed by at least one compression bolt penetrating through the two connecting blocks. The two sections of contact rails can relatively slide in the length direction of the connecting blocks. The connecting blocks are made of conductive materials, gaps exist between the two side faces of the connecting blocks and the two inner side walls of the containing grooves, and spring touch fingers in a long-strip shape after being spread are arranged between the inner end faces of the connecting blocks and the bottoms of the containing grooves. By means of the expansion joint of the contact rails, the mechanical connection and the conductive connection of the connecting blocks and the contact rails are achieved through the same set of expansion joint, and the contact rails are more simple in structure and lighter.
