Therefore, the first extension arm 2232 is fixed on the first outer shielding surface 2241 of the second shielding member 224, so that the first shielding member 223 and the second shielding member 224 can be fixed to each other, and there is no need to provide a fixing hole on the first shielding member 223 or the second shielding member 224, which reduces interference caused by external interference signals entering the first shielding space to the first terminal 221, and the first grounding tab 24 can conduct a plurality of second shielding members 224 into an integral grounding shielding structure, so that the shielding effect of the electrical connector 100 is good; by providing the relief region 241, the thickness of the first extension arm 2232 and the thickness of the first grounding plate 24 are prevented from being overlapped, so that the thickness of the electrical connector 100 can be reduced. It should be noted that, in the present embodiment, the relief area 241 is an area that penetrates through the bare space of the first ground strip 24 along the thickness direction of the first ground strip 24, but in other embodiments, the relief area 241 may also be an area that is recessed from one side of the first ground strip 24 and does not penetrate through the first ground strip 24, for example, the thickness of the first ground strip 24 is greater than the thickness of the first extension arm 2232, and the relief area 241 is recessed from the surface of the first ground strip 24 corresponding to the thickness of the first extension arm 2232.

Referring to fig. 5 to 7, the first ground plate 24 has a plurality of first spokes 242 and a plurality of second spokes 243, the first spokes 242 simultaneously contact with a plurality of first outer shielding surfaces 2241 in the first column, each of the second spokes 243 is fixed to a corresponding one of the first outer shielding surfaces 2241 in the first column, and each of the second spokes 243 is connected to the first spokes 242 in a crossing manner.

The first shield 223 has a plurality of first extension arms 2232, the plurality of first extension arms 2232 being formed extending from different edges of the first body portion 2231, the plurality of first extension arms 2232 being completely offset along the extension length of the first body portion 2231. Compared to the plurality of first extension arms 2232 that are not completely staggered to cause the first extension arms 2232 on different sides are opposite and opposite to each other, in this embodiment, the first main body 2231 and the second shielding member 224 are fixed by the staggered plurality of first extension arms 2232 within a larger length range, and the corresponding avoidance area 241 is staggered to avoid that the avoidance area 241 is opposite and opposite to each other to cause the strength of a certain position of the first grounding piece 24 to be reduced after being set, and in this embodiment, the risk of breaking the first grounding piece 24 can be reduced. In this embodiment, the relief area 241 is configured as a notch, and in other embodiments, the relief area 241 may not be configured as a notch, for example, the relief area is integrally inwardly recessed from the side edge of the second spoke 243, so that the overall width of the second spoke 243 is reduced to form the relief area 241 on the side edge of the second spoke 243; alternatively, the relief region 241 is a hole with a limited size formed on the plane of the first ground plate 24.

Further, the plurality of first extension arms 2232 includes two first extension arms 2232 disposed adjacent to each other along a length direction of the first main body 2231, the two first extension arms 2232 are respectively adjacent to both side edges of the first spoke 242, and the two first extension arms 2232 are formed by extending from different edges of the first main body 2231. Therefore, two first extension arms 2232 formed by extending different edges can be attached to two side edges of the first spoke 242, so that the two first extension arms 2232 can limit and stop the first grounding strip 24 near the first spoke 242, thereby better preventing the first spoke 242 from displacing, increasing the stability between the first grounding strip 24 and the plurality of second shielding members 224, preventing the first spoke 242 from being separated from the plurality of second shielding members 224 to affect the conduction between the plurality of second shielding members 224, and ensuring the shielding effect of the electrical connector 100.

Referring to fig. 5 to 7, the relief area 241 is a notch, two adjacent notches are disposed on one of the second spokes 243, and the two notches are disposed on two sides of the first spoke 242 and are located on the first spoke 242 along the upper limit of the extension length of the second spoke 243. The first spoke 242 has a plurality of through holes 244 arranged along the extending direction thereof, the insulating body 21 has a plurality of protrusions 219, and each protrusion 219 is fixed in a corresponding one of the through holes 244. Compared with the relief area 241 not being arranged as the notch, the area of the relief area 241 of the first grounding plate 24 can be reduced, the fixing area of the first grounding plate 24 and the first outer shielding surface 2241 can be increased, and the first grounding plate 24 and the first extension arm 2232 can be better limited by the first extension arm 2232 extending into the notch, especially the first spoke 242 can be limited to reduce the displacement of the first spoke 242; the first spoke 242 is further prevented from being displaced by the through hole 244 and the protrusion 219, and the position stability between the first ground strip 24 and the first and second shields 223 and 224 is increased. In this embodiment, each of the first extending arms 2232 is disposed adjacent to the first spoke 242 and along the extended length of the second spoke 243 at the side edge of the first spoke 242. Of course, in other embodiments, a portion of the first extension arms 2232 of the plurality of first extension arms 2232 may be disposed adjacent to the first spoke 242 and along the extension length of the second spoke 243 and up to the side edge of the first spoke 242, and the present invention is not limited to such a configuration of all of the first extension arms 2232. By limiting the first extension arm 2232 to the side edge of the first spoke 242, the risk that the first spoke 242 is displaced to affect the conduction of the second shielding members 224 by the first grounding strip 24 is reduced. Of course, in other embodiments, the first extension arm 2232 can be disposed on the second spoke 243 and not adjacent to the side edge of the first spoke 242.
