Specifically, the first cantilever 422 is a flexible oblique sheet, the ends of the first cantilever 422 of the pair of first cantilever structures 42 away from the first contact 424 are respectively connected to the side of the two first side plates 221 of the first support part 22 facing the second support part 24, and the first cantilever 422 is oblique to the insertion slot 21, so that the first contact 424 and the first end 426 are accommodated in the insertion slot 21; the second cantilever 442 is a flexible oblique sheet, the ends of the second cantilever 442 of the pair of second cantilever structures 44 away from the second contact 444 are respectively connected to the side of the two second side plates 241 of the second support part 24 facing the first support part 22, and the second cantilever 442 is oblique to the insertion slot 21, so that the second contact 444 and the second end 446 are accommodated in the insertion slot 21.

[0049] In other embodiments, the first cantilever 422 can be, but is not limited to, a flexible arc-shaped sheet, etc., and the second cantilever structure 44 can be, but is not limited to, a flexible arc-shaped sheet, etc.

[0050] Optionally, the length of the first cantilever structure 42 extending along the length direction of the insertion slot 21 is less than the length of the second cantilever structure 44 extending along the length direction of the insertion slot 21, so that the contact portion 40 can be close to the entrance of the insertion slot 21, and a shorter coupling height is obtained when the connector terminal 100 is coupled with the mating terminal, thereby reducing the height of the connector provided with the connector terminal 100, and facilitating the miniaturization of the connector. Specifically, the length of the first cantilever 422 extending along the length direction of the insertion slot 21 is less than the length of the second cantilever 442 extending along the length direction of the insertion slot 21. In other embodiments, the length of the first cantilever structure 42 extending along the length direction of the insertion slot 21 is equal to or greater than the length of the second cantilever structure 44 extending along the length direction of the insertion slot 21.

The spacing L1 of the first clamping gap 427 is at the mouth of the connector terminal 100, and when the spacing L1 is greater than the spacing L2, the spacing L1 does not block the spacing L2, facilitating the measurement of the size of the spacing L2; in addition, the first cantilever structure 42 is provided to be smaller than the second cantilever structure 44, that is, the length of the first cantilever 422 is smaller than the length of the second cantilever 442, so as to reduce the coupling height. Since the first cantilever 422 is shorter, the spacing L1 is set to be slightly greater than the spacing L2, so that the normal pressure of the first contact 424 of the first cantilever structure 42 is similar to the normal pressure of the second contact 444 of the second cantilever structure 44, so that the contact points can be reliably contacted, and the insertion and extraction of the mating terminal can be facilitated

In other embodiments, the included angle a between the first ends 426 of the pair of first cantilever structures 42 is equal to the included angle b between the second ends 446 of the pair of second cantilever structures 44; or the included angle a between the first ends 426 of the pair of first cantilever structures 42 is greater than the included angle b between the second ends 446 of the pair of second cantilever structures 44.

The second support portion is provided with protrusions 245, which are slightly higher than the outer surface of the second support portion 24, and the protrusions 245 are used to cooperate with the connector rubber core to form an interference fit, so that the connector terminal 100 can be placed centrally in the connector rubber core; the outer surface of at least one of the second side plates 241 of the second support portion 24 is provided with protrusions 245, and in this embodiment, the outer surface of both of the second side plates 241 of the second support portion 24 is provided with protrusions 245, so that the connector terminal 100 can be placed centrally in the connector rubber core. The main body 20 further comprises a cover plate 27, which is connected to one end of the second support portion 24 away from the first support portion 22, and the cover plate 27 covers the insertion slot 21; since the cover plate 27 is closely attached to the tail plane of the second support portion 24 to cover the insertion slot 21, the cover plate 27 can prevent glue from leaking when the connector terminal 100 is glued or encapsulated at the tail portion, and prevent glue from flowing into the insertion slot 21.

[0054] The connector terminal 100 is formed by stamping an integral structure from a plate material of the same thickness, so the thickness of the first support portion 22, the thickness of the second support portion 24, the thickness of the connecting strip 26, the thickness of the first cantilever structure 42, the thickness of the second cantilever structure 44, and the thickness of the connecting portion 60 are consistent. In other embodiments, the thickness of the connector terminal 100 gradually decreases from the connecting portion 60 to the first support portion 22, so as to increase the elastic force of the first cantilever structure 42 and the second cantilever structure 44, and to enable the connector terminal 100 to be stably inserted with a mating terminal.
