The male terminal 10 has multiple openings along the circumferential direction of the outer side wall of the end portion. The reed connector 20 includes a plurality of independent reeds 210, the independent reeds 210 are inserted into the installation grooves 110 to be electrically connected with the male terminals 10, and the independent reeds 210 at least partially protrude from the male terminals 10. The outer side wall; the female terminal 30 is provided with an insertion slot 310 along one end, the end of the male terminal 10 where the reed connector 20 is installed is inserted into the insertion slot 310, and the independent reed 210 is suitable for the slot of the insertion slot 310 The wall abuts for electrical connection with the female terminal 30 .

It should be noted that the reed connector 20 is used as a contact between the male terminal 10 and the female terminal 30 to play the role of connecting the male terminal 10 and the female terminal 30. The outer side wall of the male terminal 10 is opened along its axis direction. There are a plurality of installation slots 110, and the plurality of installation slots 110 are respectively used for clamping a plurality of independent reeds 210, so that the independent reeds 210 can be installed on the male terminal 10 first and then connected with the female terminal 30. The installation method More convenient and controllable. Also, since the plurality of independent reeds 210 are provided independently, rather than integrally, the contact area can be adjusted according to the number of the independent reeds 210 . It is also easier to replace the independent reeds 210, and the service life of the contacts can also be improved by replacing the reeds regularly.

Specifically, because one end face of the independent reed 210 is in contact with the groove wall of the mounting groove 110 of the male terminal 10 , the independent reed 210 is in surface contact with the male terminal 10 , and thus the independent reed 210 is in contact with the male terminal 10 . larger area. Further, because the male terminal 10 is at least partially protruded from the outer side wall of the male terminal 10 , when the male terminal 10 is connected to the female terminal 30 , the end face of the protruding part of the independent spring 210 will also be connected to the socket of the female terminal 30 . 310 is in contact with the groove wall surface, thus increasing the contact area between the independent reed 210 and the female terminal 30.
