The design purpose of the wiring terminal is to ensure a reliable connection between the battery and other devices, and at the same time prevent the occurrence of short circuits and other safety problems.

[0003] Chinese Patent Publication No. CN209592171U, publication date November 5, 2019, discloses a battery wiring terminal mechanism, a power battery system and an electric vehicle. The battery wiring terminal mechanism includes a fixing plate, a charging wiring terminal assembly and a discharging wiring terminal assembly arranged on the fixing plate, and a series component; the charging wiring terminal assembly includes a positive charging wiring terminal and a negative charging wiring terminal penetrating through the fixing plate; the discharging wiring terminal assembly includes a positive discharging wiring terminal and a negative discharging wiring terminal penetrating through the fixing plate; wherein, the positive discharging wiring terminal and the positive charging wiring terminal are arranged side by side.

[0004] Existing battery wiring terminals for electric vehicles such as the above are mostly composed of a terminal base, a cable and a card connected to the open end of the cable. The side of the cable away from the card is peeled and connected with a connector head, and then the connector head is clamped inside the terminal base. In the specific implementation process, when different cables are connected to different positions of the battery, the cables inevitably generate traction force, which will directly act on the connection between the cable and the terminal base, resulting in the separation of the connector head from the terminal base or the breakage between the connector head and the cable. Therefore, it is urgent to propose a corresponding battery wiring terminal for electric vehicles to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a battery wiring terminal for an electric vehicle to solve the above problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A battery wiring terminal for an electric vehicle includes a terminal base and a cable. Two connecting seats are fixedly connected to the outer surface of the terminal base. A plurality of triangular frames are fixedly connected between the two connecting seats. The plurality of triangular frames are arranged horizontally, and a top plate fixedly connected to the connecting seat is arranged at the top of the plurality of triangular frames. A driving rod is screwed to the inner surface of the top plate, and a positioning component for positioning the cable is arranged at the open end of the driving rod.

[0008] Preferably, an outer sleeve rotatably connected to the top of the top plate is provided on the outer side of the top of the driving rod. A vertical rod is slidably connected to the inner wall of the outer sleeve. A spring is fixedly connected between the bottom of the vertical rod and the inner wall of the bottom of the outer sleeve. The top of the vertical rod is fixedly connected with a limiting frame that abuts against the top of the driving rod.

[0009] Preferably, a convex plate for limiting the limiting frame is fixedly connected to the top of the top plate.

[0010] Preferably, the positioning assembly includes a positioning plate. The outer wall of the positioning plate is slidably connected to the inner wall of the triangular frame through a chute. The bottom of the driving rod is rotatably connected to the top of the positioning plate.

[0011] Preferably, two adjacent sets of the multiple triangular frames are fixedly connected by two connecting blocks, and the two connecting blocks are symmetrically distributed longitudinally.

[0012] Preferably, the top plate is fixedly connected to the connecting seat through a locking rod. A side frame is fixedly connected to the outer wall of the connecting seat. The side frame is fixedly connected to the end seat through screws.

[0013] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0014] 1. In this application, after passing the chuck through the corresponding triangular frame and engaging it with the inside of the end seat, the top plate is fixed to the connecting seat through the locking rod. Then, rotate the driving rod. While the driving rod is screwed with the top plate, it provides a driving force for the positioning plate. The positioning plate moves downward until it closely adheres to the outer wall of the cable, thereby realizing the local positioning of the cable. During the connection process at the open end of the cable, the generated traction force will act on the connection between the positioning plate and the cable, rather than directly on the connection between the cable and the end seat, thereby effectively improving the stability of the battery terminal for electric vehicles.

[0015] 2. In this application, the limiting frame drives the vertical rod in a linkage manner. The vertical rod slides on the inner wall of the outer sleeve and stretches the spring. Then, the outer sleeve is driven to rotate by 90 degrees through the limiting frame. The spring drives the limiting frame through the vertical rod, so that the limiting frame stably abuts against the top of the driving rod. The frictional force generated between the limiting frame and the driving rod can effectively limit the loosening of the driving rod, thereby further ensuring the stability of the battery terminal for electric vehicles.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0024] A battery terminal for an electric vehicle includes an end seat 1 and a cable 2. Two groups of connection seats 3 are fixedly connected to the outer surface wall of the end seat 1. A plurality of groups of tripods 7 are fixedly connected between the two groups of connection seats 3. The plurality of groups of tripods 7 are arranged horizontally, and a top plate 5 fixedly connected to the connection seat 3 is provided at the top of the plurality of groups of tripods 7. A driving rod 10 is screwed to the inner surface wall of the top plate 5, and a positioning component for positioning the cable 2 is provided at the open end of the driving rod 10;

[0025] After passing the chuck through the corresponding tripod 7 and engaging it with the inside of the end seat 1, the top plate 5 is fixed to the connection seat 3 through the locking rod 6. Then, the driving rod 10 is rotated. While the driving rod 10 is screwed with the top plate 5, it provides a driving force for the positioning plate 9. The positioning plate 9 moves downward until it closely adheres to the outer surface wall of the cable 2, thereby realizing the local positioning of the cable 2. During the connection process at the open end of the cable 2, the generated traction force will act on the connection between the positioning plate 9 and the cable 2, rather than directly acting on the connection between the cable 2 and the end seat 1, thereby effectively improving the stability of the battery terminal for an electric vehicle.

[0026] Specifically, as Figure 2 And Figure 4As shown in the figure, an outer sleeve 14 rotatably connected to the top of the top plate 5 is provided on the outer side of the top of the driving rod 10. A vertical rod 13 is slidably connected to the inner wall of the outer sleeve 14. A spring is fixedly connected between the bottom of the vertical rod 13 and the inner wall of the bottom of the outer sleeve 14. The top of the vertical rod 13 is fixedly connected with a limiting frame 12 that abuts against the top of the driving rod 10. The vertical rod 13 is linked by the limiting frame 12. The vertical rod 13 slides on the inner wall of the outer sleeve 14 and stretches the spring. Then, the outer sleeve 14 is driven by the limiting frame 12 to rotate by 90 degrees. The spring links the limiting frame 12 through the vertical rod 13, so that the limiting frame 12 stably abuts against the top of the driving rod 10. The frictional force generated between the limiting frame 12 and the driving rod 10 can effectively limit the loosening of the driving rod 10, thereby further ensuring the stability of the battery terminal for electric vehicles. A convex plate 15 for limiting the limiting frame 12 is fixedly connected to the top of the top plate 5. When the driving rod 10 is rotated, the outer sleeve 14 can be rotated, and the limiting plate 12 can be temporarily limited by the convex plate 15.

[0027] Specifically, as Figure 2 shown in Figure 3 the figure, the positioning assembly includes a positioning plate 9. The outer wall of the positioning plate 9 is slidably connected to the inner wall of the triangular frame 7 through a chute 8. The bottom of the driving rod 10 is rotatably connected to the top of the positioning plate 9. When the driving rod 10 is screwed with the top plate 5, a driving force is provided for the positioning plate 9. The positioning plate 9 moves downward until it closely adheres to the outer wall of the cable 2, thereby realizing the local positioning of the cable 2. Adjacent two groups among multiple groups of triangular frames 7 are fixedly connected by two connecting blocks 11, and the two connecting blocks 11 are longitudinally symmetrically distributed, ensuring the stability of the connection between the triangular frames 7 while avoiding movement conflicts with the positioning plate 9. The top plate 5 is fixedly connected to the connecting seat 3 through a locking rod 6. A side frame 4 is fixedly connected to the outer wall of the connecting seat 3, and the side frame 4 is fixedly connected to the end seat 1 through screws, thereby ensuring the convenience of disassembly and assembly of the triangular frame 7 and the connecting seat 3.

[0028] Working principle: After passing the chuck through the corresponding tripod 7 and engaging it with the inside of the end seat 1, the top plate 5 is fixed to the connecting seat 3 through the locking rod 6. Then, the driving rod 10 is rotated. While the driving rod 10 is screwed with the top plate 5, it provides a driving force for the positioning plate 9. The positioning plate 9 moves downward until it closely adheres to the outer wall of the cable 2, thereby realizing the local positioning of the cable 2. During the connection process of the open end of the cable 2, the generated traction force acts on the connection between the positioning plate 9 and the cable 2, rather than directly on the connection between the cable 2 and the end seat 1, thereby effectively improving the stability of the battery terminal for electric vehicles. The limiting frame 12 drives the vertical rod 13 in linkage. The vertical rod 13 slides on the inner wall of the outer sleeve 14 and stretches the spring. Then, the outer sleeve 14 is driven by the limiting frame 12 to rotate by 90 degrees. The spring drives the limiting frame 12 through the vertical rod 13, so that the limiting frame 12 stably abuts against the top of the driving rod 10. The frictional force generated between the limiting frame 12 and the driving rod 10 can effectively limit the loosening of the driving rod 10, thereby further ensuring the stability of the battery terminal for electric vehicles during use.

Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
