The shield contact front groove 6016 and the shield contact side groove 6017 are also used for inserting the shield contacts in two directions in the terminal module 5.

For example, the terminal module 5 has two shield plates, a first shield plate and a second shield plate, respectively, and the shield contact at the lower end of each shield plate has a front shield claw, a side shield claw, and a rear shield claw. The shield contact front-end groove 6016 and the shield contact side-end groove 6017 correspond to a front shield claw and a side shield claw of the lower end of the shield plate, respectively. The shielding contact and the plug shielding sheet 201 which are inserted into the insertion groove are mutually pressed under the limit of the extrusion of the groove wall, so that the shielding effect of synchronous grounding is realized.

Among the plurality of slots 601 on the socket housing 6, a shield contact rear slot 6018 opposite to the shield contact front slot 6016 is provided on the other side of the signal terminal contact slot 6013 in one slot at the extreme end of each row of slots 601. The shield contact rear slots 6018 allow for the simultaneous insertion of corresponding terminal module shield contacts (e.g., rear shield fingers) and plate-like shield blades in the plug.

A shielding contact partition plate 6015 is arranged on one inner side wall of the shielding contact front-end groove 6016 and one inner side wall of the shielding contact rear-end groove 6018, and a gap is arranged between the shielding contact partition plate 6015 and the other inner side wall of the shielding contact front-end groove 6016 or the shielding contact rear-end groove 6018. One end of the shielding contact partition 6015 facing the bottom of the socket housing 6 is provided with a guiding inclined plane, and the other end is provided with a positioning step surface. The portion of the terminal module 5 where the front shielding claws of the lower ends of the two shielding plates meet can be held on the positioning step surface to define the insertion depth. The header shield blades 201 may be guided by the guide slope into the insertion groove at the bottom of the insertion groove 601 and may be pressed by the shield contact spacer 6015. The first ribs 702 provided inside the insertion holes 701 of the conductor frame 7 are positioned opposite to the shield contact spacer 6015, and the plug shield blades 201 are pressed between the shield contact spacer 6015 and the first ribs 702, so that the plug shield blades 201 and the conductor frame 7 are well grounded together. At the same time, the conductor frame 7 is further provided with a connecting part (such as the first contact piece 802 of the shielding net 8) which is contacted with the shielding contact of the terminal module 5, so that the shielding parts of the socket and the plug are grounded together integrally, and the shielding effect is improved.

The above description of the specific embodiments is only for aiding in understanding the technical concept of the present invention and its core idea, and although the technical solution has been described and illustrated using specific preferred embodiments, it should not be construed as limiting the present invention itself. Workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit of the invention. Such modifications and substitutions are intended to be included within the scope of the present invention.
