Electrical connector with separating extensions on terminals

An anti-electromagnetic interference electrical connector having a terminal assembly is provided. The anti-EMI electrical connector includes an electrical insulation case, plural first terminals, and plural second terminals. The electrical insulation case includes a slot. Each first terminal is disposed in the electrical insulation case and includes a contact end located in the slot. Each second terminal is disposed in the electrical insulation case and in a staggered manner with the first terminals. Each second terminal includes a body and a first extended portion. The body is located in the electrical insulation case and includes a connection end located in the slot. The first extended portion extends from the body and an included angle is defined between the first extended portion and the body. The first extended portion isolates the first terminals adjacent to each of the second terminals by increasing a lateral projected area of the second terminal.
