Patent attributes
An electrical connector and a transmission wafer thereof are provided. The transmission wafer includes an insulating frame, a plurality of signal terminals and ground terminals fixed on the insulating frame, and a shielding sheet that is assembled to the insulating frame. Each of the signal terminals includes a signal contacting segment protruding from the insulating frame. Each of the ground terminals includes a ground contacting segment having a ground contact and protruding from the insulating frame. The shielding sheet includes a sheet body and a plurality of outer fixing arms extending from the sheet body. Each of the outer fixing arms corresponds in position to one of the ground contacting segments along a first direction. A free end portion of each of the outer fixing arms protrudes from the ground contact of the corresponding ground contacting segment along an insertion direction that is perpendicular to the first direction.
