The utility model relates to a novel RS485 wire for a GPRS collector. The novel RS485 wire comprises an insulation outer sheath (4). Two sets of guiding wires (3) which are insulated mutually are arranged in the insulation outer sheath (4). The novel RS485 wire is characterized in that two insulation protective sleeves (2) are further included, one end of each protective sleeve (2) is fixedly connected with one end of a pressing-connecting copper pipe (1), and the two sets of guiding wires (3) respectively penetrate through the two protective sleeves (2) and are fixedly connected with the pressing-connecting copper pipe (1). Tests show that after the novel RS485 wire for the GPRS collector is used, the phenomena of virtual connection and short circuit of the RS485 wire can be effectively reduced, wire connecting quality is greatly improved, the fact that wire connecting is smooth is guaranteed, and bad influence on success ratio of the GPRS collector is avoided.
