(26) In an embodiment, the grounding sheet 22 includes a main body portion 221, multiple grounding terminals 222, and two elastic abutment portions 223. One end of one grounding terminal 222 is connected to one side of the main body portion 221, and the other end of the one grounding terminal 222 is configured to connect the docking grounding terminal of the docking connector. The multiple grounding terminals 222 are sequentially distributed at intervals in the second direction. The two elastic abutment portions 223 are disposed at two ends of the other side of the main body portion 221 facing away from the one grounding terminal 222 separately and elastically abut against two opposite inner walls of the first housing 31 separately. In this embodiment, an elastic abutment portion 223 extends through the gap 44 and then abuts against an inner wall of the first housing 31. The main body portion 221 is formed with two first positioning holes 2211. The grounding sheet 22 is made of a metal material and is an integrally formed structure.

(27) In an embodiment, one end of each of the two elastic abutment portions 223 is connected to the main body portion 221, and the other end of each elastic abutment portion 223 extends obliquely in a direction in which one elastic abutment portion 223 faces away from the other elastic abutment portion 223. With this arrangement, the elastic abutment portions 223 elastically abut against the first housing 31, and the stability of the electrical connection between the elastic abutment portions 223 and the first housing 31 is ensured.

(28) As shown in FIGS. 7 and 8, the length of the second insulating fixed block 2121 in the first direction is greater than the length of the first insulating fixed block 2111 in the first direction. That is, the first insulating fixed block 2111 docks to part of the second insulating fixed block 2121, and the other part of the second insulating fixed block 2121 exceeds the first insulating fixed block 2111. The end of the first conductive terminals 2112 facing the cable 10 and the end of the second conductive terminals 2122 facing the cable 10 are accommodated in the other part of the second insulating fixed block 2121.

The grounding connection member 32 is connected to the end of the second side plate 3112 adjacent to the extension plate 312. The conductive module extends from the inside of the sleeve structure to a side of the extension plate 312. Since the first housing 31 is integrally formed with the grounding connection member 32, and the connection strength between the two is high, a housing is not required to be disposed around the periphery of the grounding connection member 32 to ensure the firmness of the fixing of the grounding connection member 32, that is, the second side plate 3112 and the other two side plates are omitted to be provided with an extended plate which forms a housing with the extension plate 312, thereby saving materials. In this embodiment, the part of the second insulating fixed block 2121 corresponding to the first insulating fixed block 2111 is disposed in the sleeve structure of the first housing 31, and the part beyond the first insulating fixed block 2111 is disposed on the extension plate 312.

The structural arrangement is reasonable, and it is convenient to implement the connection to the cable 10.

(32) More specifically, as shown in FIGS. 6 and 8, the conductive module is formed with an accommodating groove 2123. The second connection portion 322 is accommodated in the accommodating groove 2123. With this arrangement, the firmness of the fixing of the grounding connection member 32 is further ensured. In this embodiment, the second insulating fixed block 2121 of the second module 212 is formed with an accommodating groove 2123.

(33) Further, specifically, with continued reference to FIGS. 6 and 8, the grounding connection member 32 also includes multiple positioning portions 323. The positioning portions 323 are connected to the end of the second connection portion 322 away from the first connection portion 321. Multiple positioning grooves 2124 are formed in the groove bottom of the accommodating groove 2123. The multiple positioning portions 323 are disposed in the multiple positioning grooves 2124 in a one-to-one correspondence. With this arrangement, the firmness of the fixing of the grounding connection member 32 is further improved. In this embodiment, each of the three sides of the second connection portion 322 in the U-shaped structure is provided with a sheet-shaped positioning portion 323. Accordingly, three positioning grooves 2124 are formed, and the three positioning grooves 2124 are strip-shaped grooves.
