The invention relates to a vehicle line connector comprising a connector male seat and a plug connector. The connector male seat is internally provided with a plurality of terminals, one end of the plug connector is connected to the terminals in the connector male seat, and the other end is connected to an FPC or FFC flat cable. The plug connector comprises a housing (1) and multiple connection terminals (3), and the housing (1) is internally provided with a flat passage which passes through two sides of the housing (1). The connection terminals (3) are integrally formed structures including middle connecting rods (33) and mating ends (31) and tail ends (32) at two ends of the middle connecting rods (33), the multiple connection terminals (3) are parallelly fixed in the flat passage, the mating ends (31) are connected to the terminals in the connector male seat, and the tail ends (32) are connected to the FPC or FFC flat cable. Compared with the prior art, the vehicle line connector has the advantages of simple structure, convenient disassembly and installation, light and thin structure and stable and reliable connection.
