In addition, by providing the third mounting leg 233, the current-carrying area is further increased, and the resistance is reduced, thereby facilitating the transmission of a larger current.

Similarly, the plurality of power terminals 2 of the present disclosure include the sixth power terminal 26. The sixth power terminal 26 includes the fourth supplementary elastic arm 265 arranged side by side with the fourth elastic arm 242 and the fifth supplementary elastic arm 266 arranged side by side with the fifth elastic arm 252. Therefore, the fourth spacing slot 240 between the fourth elastic arms 242 and the fifth spacing slot 250 between the fifth elastic arms 252 are fully utilized, which increases the current-carrying area in contact with the mating power connector 200, has a higher current transmission capability, and reduces the heat generated by the power terminal when transmitting a large current. In addition, by providing the sixth mounting leg 263, the current-carrying area is further increased, and the resistance is reduced, thereby facilitating the transmission of a larger current.

The understanding of this specification should be based on those skilled in the art. Descriptions of directions, although they have been described in detail in the above-mentioned embodiments of the present disclosure, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the application, and all technical solutions and improvements that do not depart from the spirit and scope of the application should be covered by the claims of the application.
