Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0039] According to an embodiment of the first aspect of the present application, as shown in Figures 1 - 3 the female connector terminal provided by the present application includes: a main body 1 and a claw sleeve 2. Among them, one end of the main body 1 is provided with a plurality of first elastic pieces 3, and the plurality of first elastic pieces 3 are annularly arranged with a first interval 4 to construct a connection cavity 5 for connecting a male terminal; the claw sleeve 2 includes a sleeve body 6 and a plurality of claw pieces 7. The sleeve body 6 is arranged in the connection cavity 5, and the plurality of claw pieces 7 are annularly connected to the sleeve body 6 with a second interval 8, and each claw piece 7 is arranged at the first interval 4 between adjacent first elastic pieces 3 and covers the adjacent first elastic pieces 3.

[0040] In this embodiment of the present application, one end of the main body 1 is designed with a plurality of first elastic pieces 3, and these first elastic pieces 3 are annularly arranged at a certain interval. This design provides a stable connection cavity 5 for the male terminal and ensures the stability of the insertion.

[0041] It can be understood that these first elastic pieces 3 not only form the connection cavity 5, but also provide a uniform clamping force through their annular arrangement, which helps to stably clamp the male terminal.

[0042] The entire claw sleeve 2 can be made of steel. The sleeve body 6 of the claw sleeve 2 is located within the connection cavity 5, while the claw pieces 7 of the claw sleeve 2 are arranged annularly at a certain interval and connected to the sleeve body 6. The positions of the claw pieces 7 are designed at the intervals between the first elastic pieces 3 and can cover the adjacent first elastic pieces 3.

[0043] The annular arrangement of multiple first elastic pieces 3 can achieve uniform clamping of the male terminal. This uniformly distributed force helps reduce local stress concentration and avoid insufficient current-carrying capacity or loose insertion caused by too few contact points. Moreover, the first elastic pieces 3 and the male terminal are in surface contact rather than point contact, which greatly increases the contact area and thus improves the current-carrying capacity of the connector.

[0044] Through the cooperation of the claw pieces 7 of the claw sleeve 2 and the first elastic pieces 3, an additional clamping force is provided. This not only enhances the clamping stability of the female terminal to the male terminal, but also the design of the claw sleeve 2 helps protect the first elastic pieces 3 and reduce damage caused by multiple insertions and extractions. Through the protection of the claw sleeve 2, the service life of the first elastic pieces 3 is extended, which also means that the overall durability of the female terminal is improved.

[0045] Therefore, the female terminal of the connector provided in the embodiment of the present application can greatly increase the current-carrying capacity of the connector and has the characteristics of high connection stability and reliability and long service life.

[0046] There is no special limitation on the specific number of the first elastic pieces 3 in the present application. For example, it can be six or more, which can effectively improve the current-carrying capacity of the connector, provide a more uniform clamping force, and achieve stable insertion of the male terminal.

[0047] According to an embodiment of the present application, referring to Figure 1 and Figure 2 As shown, each first elastic piece 3 has an opposite first connection end 9 and a first free end 10. The first connection end 9 of each first elastic piece 3 is connected to one end of the main body 1, and the part of each first elastic piece 3 adjacent to the first free end 10 is recessed toward the central axis 11 of the connection cavity 5 to form a first clamping portion 12 for clamping the male terminal.

[0048] In this embodiment of the present application, each first elastic piece 3 has an opposite first connection end 9 and a first free end 10. The first connection end 9 is fixedly connected to one end of the main body 1, while the first free end 10 participates in forming the area for clamping the male terminal.

[0049] The part of the first elastic piece 3 adjacent to the first free end 10 is designed to be recessed toward the central axis 11 of the connection cavity 5. The recessed part constitutes the first clamping portion 12, which is the key area specifically for clamping the male terminal.

[0050] It can be understood that due to the concave design of the first clamping portion 12 of the first elastic piece 3, the clamping force can be concentrated when the male terminal is inserted, thereby effectively improving the stability and strength of clamping. Due to the design of the first clamping portion 12, the first elastic piece 3 can adaptively clamp male terminals of different sizes, providing a more accurate and stable electrical connection. Moreover, this design of the first elastic piece 3 allows it to maintain its shape and function even after multiple insertions and extractions, reducing the risk of material fatigue and damage, thereby extending the service life of the female terminal.

[0051] The concentrated clamping effect of the first clamping portion 12 not only improves the stability of the mechanical connection, but also helps to improve the current-carrying capacity of current or signal transmission due to the increase in the contact area. Moreover, the clamping force of the first clamping portion 12 combined with the additional clamping force provided by the claw sleeve 2 forms a composite clamping mechanism, further improving the stability and reliability of the overall connector.

[0052] Therefore, through the special design of the first elastic piece 3 in the embodiments of the present application, effective clamping of the male terminal is achieved, the current-carrying capacity and durability of the connector are improved, and at the same time, the insertion stability is optimized.

[0053] According to an embodiment of the present application, as shown in Figure 2 both sides of the portion of each first elastic piece 3 adjacent to the first connection end 9 are relatively concave along the length direction X to form a contraction portion 13.

[0054] Specifically, the concave wall surface of the contraction portion 13 can be an arc surface. This design of the contraction portion 13 makes the portion of the first elastic piece 3 close to the first connection end 9 become thinner, which helps to improve the elasticity of the first elastic piece 3. Higher elasticity means that when the male terminal is inserted, the first elastic piece 3 can generate a greater clamping force to ensure that the male terminal is stably clamped, improving the stability of the connection. This design can also ensure that even after multiple insertions and extractions, the first elastic piece 3 can maintain sufficient elastic recovery ability, which helps to extend the service life of the first elastic piece 3.

[0055] According to an embodiment of the present application, as shown in Figure 1 and Figure 2 the first free end 10 of each first elastic piece 3 expands outward in a direction away from the central axis 11 of the connection cavity 5.

[0056] In this embodiment of the present application, the first free end 10 of each first elastic piece 3 expands outward, that is, expands in a direction away from the central axis 11 of the connection cavity 5. This design makes the entrance of the connection cavity 5 wider, facilitating the preliminary positioning and insertion of the male terminal and reducing the difficulty of insertion.

[0057] Specifically, when the male terminal approaches the connection cavity 5 of the female terminal, the first free end 10 of the first elastic piece 3 will not immediately exert a large clamping force on the male terminal due to its outward expansion design. The male terminal can smoothly enter the connection cavity 5 with less resistance. As the male terminal is further inserted, the first elastic piece 3 begins to deform and generates a clamping force on the male terminal, and this clamping effect is further enhanced by the claw sleeve 2 to ensure the stability of the connection.

[0058] According to an embodiment of the present application, referring to Figure 1 and Figure 3 As shown, at one end of each claw piece 7 away from the sleeve body 6, there is a second clamping portion 14, and the second clamping portion 14 covers the first clamping portion 12 of the adjacent first elastic piece 3.

[0059] The specific number of the claw pieces 7 of the present application is not particularly limited. For example, it can be three or more, which can strengthen the clamping of the first clamping portion 12 of the first elastic piece 3 on the male terminal and realize the stable insertion of the male terminal.

[0060] In this embodiment of the present application, the second clamping portion 14 of each claw piece 7 can apply force to the first clamping portions 12 of two adjacent first elastic pieces 3. Such a design can effectively improve the clamping force on the male terminal, thereby enhancing the stability of the connection and contributing to improving the current-carrying capacity of the connector.

[0061] Moreover, the second clamping portion 14 not only provides additional clamping force, but also helps to protect the first elastic piece 3 by covering the first clamping portion 12 of the first elastic piece 3. This design can reduce the damage caused by multiple insertions and extractions, and contribute to extending the service life of the female terminal.

[0062] In addition, since the design of the second clamping portion 14 allows one claw piece 7 to clamp and protect two first elastic pieces 3, this structural optimization helps to reduce the number of required claw pieces 7, can reduce the weight of the overall female terminal of the connector, and reduce the manufacturing cost.

[0063] According to an embodiment of the present application, referring to Figure 3 As shown, the sleeve body 6 of the claw sleeve 2 is provided with a through hole 15.

[0064] Specifically, by providing the through hole 15 in the middle of the sleeve body 6, the amount of material used can be reduced, thereby reducing the overall weight of the claw sleeve 2 and improving the portability of the connector.

[0065] Moreover, the design of the through hole 15 helps to improve the elastic force of the claw pieces 7 on the claw sleeve 2. When the claw pieces 7 are subjected to an external force, due to the reduction of the material, their elastic deformation increases, so that the claw pieces 7 have a greater elastic restoring force. This design can make the clamping of the claw pieces 7 on the first elastic piece 3 more firm, thereby improving the clamping force of the first elastic piece 3 on the male terminal and improving the stability and reliability of the connection.

[0066] According to an embodiment of the present application, referring to Figure 1 and Figure 4 as shown, the female terminal of the connector further includes a fixing sleeve 16, and the fixing sleeve 16 is sleeved on the main body 1.

[0067] Specifically, the fixing sleeve 16 can be a steel sleeve, which has high hardness and wear resistance, and can resist the influence of external environmental factors, such as impact, extrusion, etc. During use, the fixing sleeve 16 can prevent the main body 1 from deforming or being damaged due to external force, protect the main body 1 from damage, and thus extend the service life of the female terminal.

[0068] According to an embodiment of the present application, referring to Figure 1 and Figure 4 as shown, the fixing sleeve 16 is provided with a slot 17, and a second elastic piece 18 is arranged in the slot 17. The second elastic piece 18 has opposite second connection ends 19 and a second free end 20. The second connection end 19 is connected to the side wall of the slot 17, and the second free end 20 extends outward away from the central axis 11 of the connection cavity 5.

[0069] Specifically, the fixing sleeve 16 is provided with a slot 17, and the position and size of the slot 17 are designed to accommodate the second elastic piece 18.

[0070] The second elastic piece 18 has a second connection end 19 and a second free end 20. The second connection end 19 is connected to the side wall of the slot 17 to ensure the fixation of the second elastic piece 18 on the fixing sleeve 16. The second free end 20 extends outward away from the central axis 11 of the connection cavity 5, so that when the female terminal is installed inside the insulating housing, the second free end 20 can expand outward and snap into the insulating housing to prevent the female terminal from loosening during use.

[0071] According to an embodiment of the present application, referring to Figure 4 as shown, the number of the slots 17 is multiple, and the multiple slots 17 are evenly distributed in a circumferential direction of the fixing sleeve 16. Correspondingly, the number of the second elastic pieces 18 is multiple, and the multiple second elastic pieces 18 are evenly distributed in a circumferential direction of the fixing sleeve 16. For example, the number of both the slots 17 and the second elastic pieces 18 can be three.

[0072] With such a design, it can be ensured that the female terminal can obtain a uniform clamping force when installed inside the insulating housing, so that the female terminal can be more stably fixed inside the insulating housing, reduce the risk of loosening, and contribute to improving the overall stability and reliability of the connector.

[0073] According to an embodiment of the present application, referring to Figure 1 and Figure 4As shown, the fixing sleeve 16 has opposite first end 21 and second end 22. The first end 21 of the fixing sleeve 16 is provided with a plurality of circumferentially distributed first buckles 23, and each first buckle 23 is clamped at one end of the main body 1 at the first interval 4 between adjacent first elastic pieces 3; the second end 22 of the fixing sleeve 16 is provided with a plurality of circumferentially distributed second buckles 24, and each second buckle 24 is clamped at one end of the main body 1 away from the first elastic piece 3. For example, the number of both the first buckles 23 and the second buckles 24 can be three.

[0074] Specifically, through the design of the first buckles 23 and the second buckles 24, it can be ensured that the connection between the fixing sleeve 16 and the main body 1 is more stable, reducing the possibility of loosening. And the buckle design helps to simplify the assembly process and improve production efficiency.

[0076] As Figure 1 shown, the wiring structure 25 includes a first connection portion 26, a first crimping portion 27, a second connection portion 28 and a second crimping portion 29 connected in sequence. The first connection portion 26 is connected to the end of the main body 1, the first crimping portion 27 is used to crimp the wire end, and the second crimping portion 29 is used to crimp the wire outer sheath.

[0077] As Figure 5 shown, the wiring structure 25 includes a third connection portion 30 and a wire pressing sleeve 31 connected to each other. The third connection portion 30 is connected to the end of the main body 1, and the wire pressing sleeve 31 is used to crimp the wire.

[0078] As Figure 6 shown, the wiring structure 25 includes a fourth connection portion 32 and a welding platform 33 connected to each other. The fourth connection portion 32 is connected to the end of the main body 1, and the welding platform 33 is used for ultrasonic welding of the wire.

[0079] According to an embodiment of the present application, the main body 1 of the female terminal, the first elastic piece 3 and the wiring structure 25 are integrally formed by stamping a metal sheet (such as a copper sheet) through a mold, and the claw sleeve 2 of the female terminal is integrally formed by stamping a metal sheet (such as a stainless steel sheet) through a mold. The fixing sleeve 16 of the female terminal is also integrally formed by stamping a metal sheet (such as a stainless steel sheet) through a mold. Such a design can simplify the manufacturing process and reduce the manufacturing cost.
