An electrical connector includes an insulating body, a first terminal module, and a second terminal module. The first terminal module includes a first insulating block and a first conductive terminal. The first conductive terminal includes a first mating portion. The second terminal module includes a second insulating block and a second conductive terminal. The second conductive terminal includes a second mating portion. The first conductive terminal includes a supporting portion exposed from the first insulating block. The electrical connector further includes a supporting block located behind the supporting portion along a mating direction and abutting against the supporting portion. The present disclosure improves the structural reliability of the electrical connector and facilitates miniaturization of the electrical connector.
