[0021] The present utility model will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited are not intended to limit the present utility model.

[0022] This embodiment provides a power connector that can achieve hot plugging and dual contact. A second connecting member 21 is additionally provided in the female terminal 20. The second connecting member 21 contacts the male terminal 10 to form a second contact position 40, and the second contact position 40 is used as a contact sacrificial position. The first contact position 30 formed by the contact between the first connecting member 11 and the female terminal 20 can be used as an effective contact position to conduct the circuit. In this way, the hot plugging of the power connector is realized, the purpose of live plugging and unplugging is achieved, and the formed first contact position 30 and second contact position 40 form dual contact, improving the contact reliability and enhancing the practicability of the power connector.

[0023] Combined with Figures 1 to 4 As shown, the power connector of this embodiment that can achieve hot plugging and dual contact includes a male terminal 10 and a female terminal 20. A first connecting member 11 is provided in the male terminal 10, and a second connecting member 21 is provided in the female terminal 20. After the male terminal 10 and the female terminal 20 are plugged together, the male terminal 10 contacts the second connecting member 21, and the female terminal 20 contacts the first connecting member 11.

[0024] In this embodiment, when the first connecting member 11 contacts the female terminal 20, a first contact position 30 is formed. When the second connecting member 21 contacts the male terminal 10, a second contact position 40 is formed. When the female terminal 20 is inserted into the male terminal 10, the formation time of the second contact position 40 is earlier than that of the first contact position 30. In the process of plugging the female terminal 20 and the male terminal 10 in this embodiment, the second contact position 40 is formed earlier than the first contact position 30, and the second contact position 40 is used as a contact sacrificial position. Thus, the live plugging and unplugging of the power connector is realized, and the first contact position 30 and the second contact position 40 form a dual contact operation, improving the contact reliability during the use of the power connector to ensure the normal use of the power connector.

[0025] Combined with Figure 2 、 Figure 3 And Figure 4 As shown, a first cavity 101 is provided in the male terminal 10 of this embodiment, and the first connecting member 11 is installed in the first cavity 101. A second cavity 201 is provided in the female terminal 20, and the second connecting member 21 is installed in the second cavity 201. In the process of plugging the male terminal 10 and the female terminal 20 together, the male terminal 10 contacts the second connecting member 21 first to form the second contact position 40, and then the female terminal 20 contacts the first connecting member 11 to form the first contact position 30, thereby using the second contact position 40 as a contact sacrificial position.

[0026] In this embodiment, the male terminal 10 is inserted into the second cavity 201 and contacts the second connector 21 to form the second contact position 40. A contact protrusion 50 is arranged in the second cavity 201. The contact protrusion 50 is inserted into the first cavity 101 and forms the first contact position 30 with the first connector 11. After the second contact position 40 is used as a contact sacrificial position, the first contact position 30 serves as an effective contact position to conduct the circuit, thereby realizing the hot plugging and unplugging of the power connector and achieving the purpose of hot plugging and unplugging while energized.

[0027] Specifically, the contact protrusion 50 of this embodiment is integrally formed with the female terminal 20. During the insertion process of the female terminal 20 and the male terminal 10, the contact protrusion 50 is driven to continuously move.

[0028] In this embodiment, both the first connector 11 and the second connector 21 are crown spring structures to improve the contact reliability of the first contact position 30 and the second contact position 40.

[0029] This embodiment can realize the hot plugging and unplugging and double contact of the power connector. In actual use, during the insertion process of the male terminal 10 and the female terminal 20, first, when the second connector 21 contacts the male terminal 10, the second contact position 40 is formed. Then, during the continuous insertion process of the male terminal 10 and the female terminal 20, the first connector 11 contacts the female terminal 20 to form the first contact position 30. Therefore, during the insertion process of the male terminal 10 and the female terminal 20, the formation time of the second contact position 40 is earlier than that of the first contact position 30. Thus, the second contact position 40 is used as a contact sacrificial position, thereby realizing the hot plugging and unplugging of the power connector while energized. The combined use of the first contact position 30 and the second contact position 40 forms a double contact operation, improving the contact reliability during the use of the power connector to ensure the normal use of the power connector.

[0030] In summary, for the power connector of this embodiment, a second connector 21 is additionally arranged in the female terminal 20. The second connector 21 contacts the male terminal 10 to form the second contact position 40. Using the second contact position 40 as a contact sacrificial position, while the first contact position 30 formed by the first connector 11 contacting the female terminal 20 can serve as an effective contact position to conduct the circuit, thereby realizing the hot plugging and unplugging of the power connector and achieving the purpose of hot plugging and unplugging while energized. Moreover, the formed first contact position 30 and second contact position 40 form a double contact, improving the contact reliability and enhancing the practicability of the power connector.

[0031] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of this utility model creation.
