[0032] The first conductive elastic piece 13 is arranged on the inner circumferential surface of the first plug-in cavity 111, and is welded and fixed with the first conductive base 11. Specifically, the first conductive elastic piece 13 is arranged on the inner circumferential surface of the first sub-cavity 112, and one end of the first conductive elastic piece 13 towards the second conductive base 12 abuts against the first limiting boss 116, that is, the first fixed ring 131 close to the second conductive base 12 abuts against the first limiting boss 116. The outer circumferential surfaces of the two first fixed rings 131 are in close contact with the inner circumferential surface of the first sub-cavity 112 of the first plug-in cavity 111, so that the first conductive elastic piece 13 is fixedly connected and electrically connected with the first conductive base 11. The outer circumferential surface of the first abutting cylinder 133 and the inner circumferential surface of the first sub-cavity 112 of the first plug-in cavity 111 form a first avoiding cavity 117.

[0033] In other embodiments, a U-shaped sleeve can be used to fixedly connect the first conductive elastic piece 13 with the first conductive base 11. The U-shaped sleeve not only can fix the first conductive elastic piece 13, but also can protect the first conductive elastic piece 13. Specifically, the external to-be-mated terminal 20 is inserted obliquely to first contact the U-shaped sleeve, and then is guided to contact the first conductive elastic piece 13, which is beneficial to increase the service life of the first conductive elastic piece 13.

[0034] The second conductive elastic piece 14 is arranged on the inner circumferential surface of the second plug-in cavity 121. Specifically, the second conductive elastic piece 14 is arranged on the inner circumferential surface of the second matching section 126, and one end of the second conductive elastic piece 14 away from the first conductive elastic piece 13 abuts against the second limiting boss 127, that is, the second fixed ring 141 of the second conductive elastic piece 14 away from the first conductive elastic piece 13 abuts against the second limiting boss 127, and the outer circumferential surfaces of the two second fixed rings 141 of the second conductive elastic piece 14 are in close contact with the inner circumferential surface of the second matching section 126 of the second plug-in cavity 121, so that the second conductive elastic piece 14 is fixedly connected and electrically connected with the second conductive base 12.

The second conductive elastic piece 14 and the first conductive elastic piece 13 are arranged in the X-axis direction.

[0035] The to-be-mated terminal 20 includes the plug pin 21 and the second external section 22 fixedly connected in the X-axis direction, and the second external section 22 is provided with a second wire pressing cavity 221 on the end surface away from the plug pin 21, which is used for pressing the external wire. In other embodiments, the second external section 22 can be fixedly connected and electrically connected with the external wire by means including but not limited to welding and ultrasonic welding.

[0036] When the to-be-mated terminal 20 is sequentially inserted into the first plug cavity 111 and the second plug cavity 121, the first conductive elastic piece 13 and the second conductive elastic piece 14 are elastically abutted against the outer circumferential surface of the to-be-mated terminal 20, respectively. Specifically, the pin 21 of the to-be-mated terminal 20 is sequentially inserted into the first sub-cavity 112 of the first plug cavity 111, the second guide section 125 and the second mating section 126 of the second plug cavity 121, and the outer circumferential surface of the pin 21 is abutted against the plurality of first elastic sheets 132 of the first conductive elastic piece 13 and the plurality of second elastic sheets 142 of the second conductive elastic piece 14, respectively. The plurality of first elastic sheets 132 and the plurality of second elastic sheets 142 are elastically deformed towards the first avoiding cavity 117 and the second avoiding cavity 144, respectively, and the plurality of first elastic sheets 132 and the plurality of second elastic sheets 142 are elastically abutted against the outer circumferential surface of the pin 21, respectively, so that the first conductive elastic piece 13 is fixedly and electrically connected with the to-be-mated terminal 20, and the second conductive elastic piece 14 is fixedly and electrically connected with the to-be-mated terminal 20, thereby fixedly and electrically connecting the to-be-mated terminal 20 with the connector terminal 10.

[0037] In the embodiment, the connector terminal 10 is provided with the first conductive elastic piece 13 and the second conductive elastic piece 14, both of which are used to abut against the external to-be-mated terminal 20. When the connector terminal 10 is plugged with the external to-be-mated terminal 20, the contact area between the connector terminal 10 and the to-be-mated terminal 20 is larger, thereby improving the current carrying capacity of the connector terminal 10. In addition, the connector terminal 10 is used for a connector, and the connector can transmit a larger current.

[0038] The design of arranging the first conductive elastic piece 13 and the second conductive elastic piece 14 along the X-axis direction reduces the cross-sectional area of the connector, which is conducive to the miniaturization design of the connector. In addition, the first conductive elastic piece 13 is mounted on the first conductive base body 11, the second conductive elastic piece 14 is mounted on the second conductive base body 12, and the first conductive base body 11 is fixedly connected with the second conductive base body 12, thereby completing the assembly of the connector terminal 10. The structure is simple and convenient to assemble, which is conducive to providing assembly efficiency and reducing production cost.

[0039] In other embodiments, the number of the first conductive elastic members 13 is multiple, and the multiple first conductive elastic members 13 are arranged on the inner circumferential surface of the first sub-cavity 112 of the first insertion cavity 111 and arranged along the X-axis direction. The number of the second conductive elastic members 14 is multiple, and the multiple second conductive elastic members 14 are arranged on the inner circumferential surface of the second insertion cavity 121 and arranged along the X-axis direction. When the to-be-mated terminal 20 is sequentially inserted into the first sub-cavity 112 and the second insertion cavity 121, the multiple first conductive elastic members 13 and the multiple second conductive elastic members 14 are respectively elastically abutted against the outer circumferential surface of the to-be-mated terminal 20. The more the number of the first conductive elastic members 13 and the number of the second conductive elastic members 14, the greater the contact area when the connector terminal 10 and the to-be-mated terminal 20 are inserted and connected, and the greater the current that can be transmitted by the connector.

[0040] In the embodiment, the design that the second conductive base body 12 is inserted into the second sub-cavity 113 of the first conductive base body 11 makes the structure of the connector terminal 10 compact, which is beneficial to the miniaturization design of the connector terminal 10, and the stability of the connection between the second conductive base body 12 and the first conductive base body 11 is higher.

[0041] In the embodiment, by dividing the second sub-cavity 113 into the first guiding section 115 and the first matching section 114, and making the caliber of the first guiding section 115 larger, the second conductive base body 12 is more easily inserted into the second sub-cavity 113, and the assembly is convenient. Moreover, by arranging the first insertion section 122 and the second insertion section 123 on the second conductive base body 12, and making the diameter of the first insertion section 122 smaller, the second conductive base body 12 is more easily inserted into the second sub-cavity 113, and the assembly is more convenient.

[0042] In the embodiment, by arranging the first limiting boss 116 to limit the first conductive elastic member 13 in the X-axis direction, the first conductive elastic member 13 can be stably fixed in the first sub-cavity 112.

[0043] In the embodiment, by arranging the second limiting boss 127 to limit the second conductive elastic member 14 in the X-axis direction, the second conductive elastic member 14 can be stably fixed in the second insertion cavity 121.

[0044] In the embodiment, by arranging the second guiding section 125, when the second conductive elastic member 14 is arranged on the second conductive base body 12, the second guiding section 125 pre-guides the second conductive elastic member 14, which is convenient for assembly, and after the second conductive elastic member 14 is arranged on the second matching section 126, the second guiding section 125 is closed, that is, by external force, the diameter of the second guiding section 125 is made smaller than the outer diameter of the second conductive elastic member 14, so as to prevent the second conductive elastic member from being pulled out.

[0045] In the embodiment, the outer circumferential surface of the second insertion section 123 is provided with a second positioning boss 129, which is located on the side of the first positioning boss 128 away from the first conductive base 11. When the connector terminal 10 is assembled with the external rubber core, the connector terminal 10 is positioned with the rubber core through the second positioning boss 129.
