[0039] The technical solution adopted by this utility model to solve its technical problem is:

[0040] like Figures 1 to 2 As shown, some embodiments of this utility model disclose a battery electrode connector, which may include a main body 10, an elastic clamping member 20, a wire 30, a driving assembly 40, a fixing assembly 50, and a connecting assembly 60. The elastic clamping member 20 is disposed at one end of the main body 10 via the connecting assembly 60. The wire 30 passes through the main body 10 and is fixed by the fixing assembly 50; one end of the wire 30 is disposed on the inner wall of the elastic clamping member 20, and the other end passes through the main body 10 for conducting electricity to the battery. The driving assembly 40 is movably disposed on the main body 10 and can drive the elastic clamping member 20 to move back and forth between a closed position and an expanded position; when the driving assembly 40 moves the elastic clamping member 20 from the expanded position to the closed position, the elastic clamping member 20 causes the wire 30 to contract to wrap around the battery electrode; when the driving assembly 40 moves the elastic clamping member 20 from the closed position to the expanded position, the elastic clamping member 20 causes the wire 30 to expand to release the battery electrode.

[0041] Continue to refer to Figure 2In some embodiments, the main body 10 may include a tube 11 and at least two fastening parts 12. The at least two fastening parts 12 are tapered and are disposed at one end of the tube 11; the aforementioned wire 30 passes through the tube 11 and the at least two fastening parts 12.

[0042] In some embodiments, when the fixing component 50 applies a predetermined driving force to the at least two fastening portions 12, the at least two fastening portions 12 elastically deform and contract to clamp and fix the wire 30. When the fixing component 50 reduces the predetermined driving force on the at least two fastening portions 12, the at least two fastening portions 12 expand under elastic force, releasing the wire 30.

[0043] together Figure 3 and Figure 4 In some embodiments, the elastic clamping member 20 may include a ring body 21, at least two elastic clamping arms 22, a first through hole 23, and a second through hole 24. The ring body 21 is disposed at the end of the tube body 11 away from the fastening part 12 via the aforementioned connecting assembly 60, and the ring body 21 is coaxially arranged with the main body 10. At least two elastic clamping arms 22 are disposed at the end of the ring body 21 away from the tube body 11 and have a tapered structure; the at least two elastic clamping arms 22 are made of elastic material. The first through hole 23 is formed through the circumferential surface of the ring body 21, and the second through hole 24 is formed on the elastic clamping arms 22.

[0044] In some embodiments, the aforementioned driving component 40 acts on at least two elastic clamping arms 22 to drive the at least two elastic clamping arms 22 to elastically deform when a predetermined driving force is applied to the at least two elastic clamping arms 22, thereby achieving closing; and when the predetermined driving force is removed or reduced, the at least two elastic clamping arms 22 reset or partially reset, thereby achieving expansion.

[0045] In some embodiments, the aforementioned driving component 40 acts on at least two elastic clamping arms 22 to drive the at least two elastic clamping arms 22 to elastically deform and expand when a predetermined driving force is applied to the at least two elastic clamping arms 22; and when the predetermined driving force is removed or reduced, the at least two elastic clamping arms 22 are reset or partially reset and close.

[0046] In some embodiments, six elastic clamping arms 22 are provided and are circumferentially distributed on the ring body 21. Of course, in other embodiments, the number of elastic clamping arms 22 can be any number, such as three, four, or five, and can be set according to actual needs.

[0047] Continue to refer to Figure 2In some embodiments, the conductor 30 may include a conductor 31 and an insulating sleeve 32 wrapped around the conductor 31. The conductor 31 passes inside the tube 11, and the insulating sleeve 32 is exposed outside the tube 11. In other embodiments, the conductor 31 and part of the insulating sleeve 32 are disposed inside the tube 11 to prevent the conductor 31 from being exposed outside the main body 10 and causing personnel to accidentally touch the live conductor 31.

[0048] For reference Figure 3 In some embodiments, the wire core 31 may include a wire core body 311, at least two conductive portions 312, and a boss 313. The wire core body 311 is inserted into the tube 11. At least two conductive portions 312 are disposed at one end of the wire core body 311 near the elastic clamping arm 22, and each conductive portion 312 has a tapered structure and is respectively disposed on the inner wall of the at least two elastic clamping arms 22. When the at least two elastic clamping arms 22 move from the expanded position to the closed position, the at least two conductive portions 312 follow the at least two elastic clamping arms 22 to close, thereby adhering to the outer surface of the battery electrode for detecting and / or transmitting electrical signals; conversely, when the at least two elastic clamping arms 22 move from the closed position to the expanded position, the at least two conductive portions 312 follow the at least two elastic clamping arms 22 to expand, thereby detaching from the battery electrode. A boss 313 is provided on the outer wall of the conductive part 312. The boss 313 is inserted into the second through hole 24 and extends out of the second through hole 24 to connect and fix the conductive part 312 to the elastic clamping arm 22.

[0049] In other words, when the drive assembly 40 applies a predetermined driving force to at least two elastic clamping arms 22 in some embodiments, it drives the at least two elastic clamping arms 22 to elastically deform, and at the same time drives the at least two conductive parts 312 to close together to clamp (wrap) onto the battery electrode; when the drive assembly 40 removes or reduces the predetermined driving force on the at least two elastic clamping arms 22 in some embodiments, the at least two elastic clamping arms 22 reset or partially reset, and at the same time drives the at least two conductive parts 312 to expand together to release (detach) from the battery electrode.

[0050] Refer again Figure 4 In some embodiments, at least two conductive portions 312 may also include contact portions 3121 disposed on the inner wall, and the shape of the contact portions 3121 matches the shape of the battery electrode, so that the contact portions 3121 make the at least two conductive portions 312 fit more closely to the battery electrode.

[0051] In some embodiments, the contact portion 3121 has a conical shape when it is in the closed position (see reference). Figure 5 ), which mates with the cone-shaped electrode; or, the contact portion 3121, when in the closed position, has a hexagonal structure (see reference). Figure 6The contact portion 3121, which mates with an electrode shaped like a hexagonal nut, has its six sides wrapping around the six sides of the hexagonal nut. Of course, in other embodiments, the battery electrode can have many shapes, and the specific shape of the contact portion 3121 is not limited here; it can be set according to the shape of the battery electrode.

[0052] Continue to refer to Figure 4 In some embodiments, six conductive portions 312 are provided, and the six conductive portions 312 are respectively attached to the inner walls of the six elastic clamping arms 22. Understandably, the insulating sleeve 32 of the wire 30 is partially peeled off, and then one end of the wire core 31 is evenly separated into six parts to form the conductive portions 312; then each conductive portion 312 is molded into one-sixth of the electrode shape using intermediate frequency molding to form a contact portion 3121 that matches the electrode, so that it exactly covers the adapted battery electrode.

[0053] like Figure 3 and Figure 7 As shown, in some embodiments, the drive assembly 40 may include a rotating member 41, a connecting member 42, a drive member 43, and an operating member 44. The rotating member 41 is threadedly connected to the main body 10, and can move back and forth along the axial direction of the main body 10 when rotating. The connecting member 42 connects the drive member 43 to the rotating member 41, allowing the drive member 43 to move back and forth along with the rotating member 41. The operating member 44 is disposed on the rotating member 41 and is used to operate the rotation of the rotating member 41. Understandably, by the operating member 44 driving the rotating member 41 to move along the axial direction of the main body 10, the rotating member 41 drives the drive member 43 to move, thereby the drive member 43 applying or reducing a predetermined driving force to at least two elastic clamping arms 22.

[0054] Continue to refer to Figure 7 In some embodiments, the rotating component 41 may include a mounting portion 411, a pulling portion 412, and a connecting portion 413. The mounting portion 411 is a cylindrical structure with internal threads on its inner wall and external threads on the outer wall of the main body 10. The mounting portion 411 is threaded onto the main body 10. The connecting portion 413 is also cylindrical, disposed on the mounting portion 411, and sleeved around the main body 10. The pulling portion 412 is disposed on the circumferential surface of the end of the connecting portion 413 away from the mounting portion 411, and its outer diameter is larger than that of the connecting portion 413. The aforementioned operating component 44 is mounted on the mounting portion 411. Rotating the operating component 44 can drive the rotating component 41 to rotate. Because the inner wall of the mounting portion 411 has internal threads and the outer wall of the main body 10 has external threads, the rotating component 41 moves along the axis of the main body 10 while rotating.

[0055] Refer again Figure 2In some embodiments, the connecting member 42 may include a base 421, a first limiting part 422, and a second limiting part 423. The base 421, the first limiting part 422, and the second limiting part 423 are all cylindrical structures. The first limiting part 422 is disposed on the top of the base 421, and the second limiting part 423 is disposed on the top of the first limiting part 422. The inner diameter of the first limiting part 422 is smaller than the inner diameter of the base 421, the inner diameter of the second limiting part 423 is smaller than the inner diameter of the first limiting part 422, and the outer diameter of the pulling part 412 is larger than the inner diameter of the second limiting part 423. The base 421 is sleeved and installed outside the aforementioned driving member 43. A rotating groove A is formed between the first limiting part 422, the second limiting part 423, and the driving member 43, and the pulling part 412 is rotatably disposed within the rotating groove A. Understandably, when the rotating member 41 rotates along the main body 10, the pulling part 412 rotates in the rotating groove A. At the same time, when the rotating member 41 moves along the main body 10, the movement of the rotating member 41 will drive the driving member 43 to move.

[0056] For reference Figure 8 In some embodiments, the driving member 43 may include a cylinder 431, a pressing part 432, and a limiting part 433. The pressing part 432 is disposed on the inner wall of the cylinder 431 and has a tapered structure. The inner diameter of the end of the pressing part 432 near the rotating member 41 is smaller than the inner diameter of the end of the pressing part 432 away from the rotating member 41. The limiting part 433 is disposed on the inner wall of the cylinder 431 and parallel to the axis of the main body 10. The portion of the aforementioned boss 313 extending out of the second through hole 24 is slidably disposed within the limiting part 433, allowing the driving member 43 to slide relative to the elastic clamping arm 22. Understandably, the limiting part 433 is an opening groove, and the portion of the boss 313 extending out of the second through hole 24 is slidably disposed within the groove. Due to the limiting position between the boss 313 and the limiting part 433, the driving member 43 can only move along the axial direction of the main body 10; therefore, the connecting member 42 and the driving member 43 will not rotate relative to the rotating member 41, but the connecting member 42 and the driving member 43 can move with the rotating member 41.

[0057] Specifically, when the rotating member 41 moves along the axis of the main body 10, it drives the pulling part 412 to move. During the movement, the pulling part 412 applies or reduces the driving force on the elastic clamping arm 22 through the pressing part 432. In other words, during the movement, the pulling part 412 abuts against the outer surface of the elastic clamping arm 22 through the pressing part 432, and the elastic clamping arm 22 changes from an expanded position to a closed position; or, during the movement, the pulling part 412 disengages from the outer surface of the elastic clamping arm 22 through the pressing part 432, and the elastic clamping arm 22 loses its abutment and undergoes elastic deformation, changing from a closed position to an expanded position.

[0058] like Figure 2 and Figure 9As shown, in some embodiments, the fixing component 50 may include a locking member 51 and a first limiting platform 52. The locking member 51 includes a body 511 and a compression portion 512 disposed on the body 511 and having a conical structure. The body 511 is sleeved on the tube 11, and the compression portion 512 abuts against the outer walls of at least two fastening portions 12. The conical structure of the compression portion 512 applies abutment force to the at least two fastening portions 12, causing the at least two fastening portions 12 to contract and apply pressure and wrapping force to the wire 30, thus fixing the wire 30 within the body 10. The first limiting platform 52 is mounted on the tube 11 and supported at the bottom of the body 511 to limit the installation position of the locking member 51, preventing the locking member 51 from rotating due to external environmental influences and causing displacement, thereby reducing the force applied to the fastening portions 12 and minimizing the instability of the wire 30's fixation.

[0059] In other words, the body 511 is threaded onto the tube 11, and when the body 511 rotates, it moves along the axis of the main body 10. When the body 511 moves closer to the elastic clamping arm 22, the compression part 512 applies pressure to the outer surfaces of at least two fastening parts 12, causing the at least two fastening parts 12 to close and clamp the wire 30. When the body 511 moves away from the elastic clamping arm 22, the compression part 512 disengages from the outer surfaces of the at least two fastening parts 12, and the at least two fastening parts 12 undergo elastic deformation and expand, thereby releasing the wire 30.

[0060] like Figure 2 and Figure 3 As shown, in some embodiments, the connecting assembly 60 may include a riveting member 61, a mounting member 62, a fixing member 63, and a second limiting platform 64. The ring 21 is fitted inside the mounting member 62, and the riveting member 61 connects the ring 21 to the mounting member 62; the riveting member 61 may be a rivet, screw, etc. Of course, in other embodiments, the ring 21 may be directly welded to the mounting member 62 or the ring 21 and the mounting member 61 may be integrally formed. The mounting member 62 is located at one end of the main body 10 near at least two elastic clamping arms 22, and the fixing member 63 is fitted onto the mounting member 62 and the main body 10 to coaxially connect the mounting member 62 and the main body 10. The second limiting platform 64 is mounted on the main body 10 and abuts against the top of the fixing member 63. The second limiting platform 64 limits the fixing member 63 to prevent it from rotating or displacing due to external environmental influences (such as vibration).

[0061] The following section will further explain the battery electrode connector in conjunction with its usage.

[0062] When using the battery electrode connector: the operator holds the first limiting platform 52 and keeps it stationary, and rotates the operating component 44 to drive the rotating component 41 to rotate. At the same time, the rotating component 41 will drive the driving component 43 to move away from the elastic clamping arm 22 or towards the elastic clamping arm 22 along the axis of the main body 10. Due to the limitation between the boss 313 and the limiting part 433, the driving component 43 can only move up and down along the axis of the main body 10.

[0063] When the driving member 43 moves downward along the axis of the main body 10, the pressing part 432 applies a predetermined driving force to at least two elastic clamping arms 22, driving at least two elastic clamping arms 22 to contract and wrap around the outer surface of the battery electrode.

[0064] When the drive member 43 moves upward along the axis of the main body 10, the predetermined driving force applied by the pressing part 432 to the at least two elastic clamping arms 22 is removed or reduced, and the at least two elastic clamping arms 22 expand under the elastic force, thereby releasing the battery electrodes.

[0065] It should be noted that, for those skilled in the art, without departing from the concept of this utility model, the above-mentioned technical features can be freely combined, and several modifications and improvements can be made, all of which fall within the protection scope of this utility model.
