The invention provides a USB connector based on TypeC. The USB connector comprises a housing and plug-in assemblies. The plug-in assemblies comprise an insulating body and a row of conductive terminals which are integrated with the insulating body. The conductive terminals comprise a first grounding terminal, a first power terminal, a signal terminal, a second power terminal, and a second grounding terminal. The USB connector is formed by two components of the housing and the plug-in assemblies, and product assembly is simple, providing convenience for automation production. The product structure is reliable, and quality is stable. The plug-in assemblies comprise the insulating body and the row of conductive terminals. The row of conductive terminals are formed in a one-time manner in an injection molding process. In an assembly process, weld legs are cut off and a housing is installed, so product coplanarity is easy to ensure. The row of conductive terminals comprise the first grounding terminal, the first power terminal, the signal terminal, the second power terminal, and the second grounding terminal, and the above terminals can be made by a same metal strip through a sheet metal forming technology, so that the number of dies is saved, and production cost is reduced.
