Electrical connector and electrical connector assembly having the same and electrical connector system

Abstract

An electrical connector assembly includes: a first connector and a second connector; a circuit board; and an electrical connector mounted on the circuit board, the first connector and the second connector connected with the electrical connector from both sides of the circuit board respectively, the electrical connector including: an insulating housing; plural pairs of terminals held in the insulating housing, each terminal pair including a first terminal and a second terminal; each first terminal includes a first elastic arm and a second elastic arm respectively exposed from both sides of the insulating housing, each second terminal includes a third elastic arm and a fourth elastic arm respectively exposed from both sides of the insulating housing, the first elastic arm and the third elastic arm are arranged in mirror symmetry with the second elastic arm and the fourth elastic arm with respect to the circuit board. The electrical connector assembly has stable signal transmission, effectively controls crosstalk, and a relatively simple structure.
