The electrical connector includes an insulation body, a terminal group and an isolation plate, where the terminal group and the isolation plate are received in the insulation body. The terminal group includes upper-row terminals and lower-row terminals. The isolation plate is between the upper-row terminals and the lower-row terminals. The isolation plate has a pair of upper grounding arms and a pair of lower grounding arms which are integrally connected with the isolation plate. The pair of upper grounding arms is in a same plane as the upper-row terminals and is on two sides of the upper-row terminals respectively. The pair of lower grounding arms is in a same plane as the lower-row terminals and is on two sides of the lower-row terminals respectively. ## Claims ### Claim 1 An electrical connector, comprising: an insulation body; a terminal group; and an isolation plate, wherein the terminal group and the isolation plate are received in the insulation body, the terminal group comprises upper-row terminals and lower-row terminals, and the isolation plate is between the upper-row terminals and the lower-row terminals, wherein the isolation plate is provided with a pair of upper grounding arms and a pair of lower grounding arms, the pair of upper grounding arms and the pair of lower grounding arms are integrally connected with the isolation plate, the pair of upper grounding arms is in a same plane as the upper-row terminals and is on two sides of the upper-row terminals respectively, the pair of lower grounding arms is in a same plane as the lower-row terminals and is on two sides of the lower-row terminals respectively. ### Claim 2 (depends on 1) The electrical connector of claim 1, wherein the isolation plate comprises a base plate, the base plate has a front surface facing the upper-row terminals and a back surface facing the lower-row terminals, each of the pair of upper grounding arms is in an elongated shape, protrudes upwardly from the front surface and extends from rear to front, wherein two ends of each of the pair of upper grounding arms are integrally connected with the base plate. ### Claim 3 (depends on 2) The electrical connector of claim 2, wherein the base plate is provided with grooves directly below the pair of upper grounding arms, the pair of upper grounding arms and the pair of lower grounding arms are in one-to-one correspondence in a vertical direction, and the groove is between the upper grounding arm and the lower grounding arm. ### Claim 4 (depends on 3) The electrical connector of claim 3, wherein the pair of upper grounding arms is formed on two sides of the front surface of the base plate in a tearing forming manner. ### Claim 5 (depends on 4) The electrical connector of claim 4, wherein the pair of lower grounding arms is below the base plate and extends in an elongated shape from rear to front, wherein each of the pair of lower grounding arms has a rear end and a front end, the rear end is integrally connected with the base plate via a U-shaped bending arm, and the front end that is a free end. ### Claim 6 (depends on 5) The electrical connector of claim 5, wherein a projection of the upper grounding arm in the vertical direction at least partially overlaps with a projection of the lower grounding arm in the vertical direction. ### Claim 7 (depends on 6) The electrical connector of claim 6, wherein the insulation body is provided with a docking tongue plate, the docking tongue plate has a top surface and a bottom surface, the upper-row terminals and the pair of upper grounding arms are disposed on the top surface, and the lower-row terminals and the pair of lower grounding arms are disposed on the bottom surface. ### Claim 8 (depends on 7) The electrical connector of claim 7, wherein the isolation plate is further provided with a first mounting leg, a second mounting leg and third mounting legs, the first mounting leg, the second mounting leg and the third mounting legs extend from a rear end of the base plate, wherein the first mounting leg and the second mounting leg extend from a rear edge of the base plate and are distributed in a front-rear direction, and the third mounting legs extend outwardly from two side edges of the base plate respectively. ### Claim 9 (depends on 8) The electrical connector of claim 8, wherein a front edge of the base plate is provided with a notch recessed backwardly, the base plate is further provided with an elongate hole vertically running through the base plate, and the front surface and the back surface are communicated by the elongate hole.
