Patent ID: 8545272

Claim:
An anti-electromagnetic interference electrical connector, comprising: an electrical insulation case comprising a slot; a plurality of signal terminals, disposed in the electrical insulation case, and each of the signal terminal respectively comprising a contact end located in the slot; and a plurality of ground terminals, disposed in the electrical insulation case; wherein the ground terminals and the signal terminals are arranged in a staggered manner, each of the ground terminals respectively comprises a body and a first extended portion, the body is located in the electrical insulation case, and the body comprises a connection end located in the slot; wherein the first extended portion is plate-like, extends from one side surface of the body toward adjacent signal terminals and through the space between the signal terminal and the ground terminal, a comprised angle is acute and defined between a widest surface of the first extended portion and a longitudinal axis of the body, and the first extended portion isolates the ground terminal of which it is a part from the signal terminals which are adjacent by increasing a lateral projected area of the ground terminal so as to block electromagnetic interference of the signal terminal.
