Description

Technical Field

[0001] This utility model belongs to the field of battery cell electrode technology, specifically relating to a protective structure for a square battery cell electrode. Background Technology

[0002] A battery cell refers to a single electrochemical cell containing positive and negative electrodes. It is generally not used directly, unlike a battery with protective circuitry and a casing. The battery cell is the energy storage component of a rechargeable battery, and its quality directly determines the quality of the rechargeable battery. The terminals on a battery cell are exposed, making them susceptible to collisions or short circuits during transport, which can damage the cell and render it unusable. Traditional protection involves placing protective sleeves on the positive and negative terminals. To prevent these sleeves from loosening and falling off, an interference fit is used, making installation difficult and prone to damaging the terminals during assembly and disassembly. This severely affects the normal operation of the battery cell and results in poor reliability.

[0003] A battery cell terminal protection cover with patent number CN206878072U includes a cover body with a cell groove that matches the outer wall of the battery cell, and a terminal slot for inserting the battery cell terminal. This utility model's battery cell terminal protection cover uses the cell groove that matches the outer wall of the battery cell to connect and fix it, facilitating installation and removal. The terminal slots effectively protect the battery cell terminal, preventing collisions or short circuits, improving transportation reliability. Furthermore, it effectively avoids applying force to the battery cell terminal during installation and removal, preventing damage and ensuring the integrity of the battery cell terminal, thus guaranteeing good performance of the battery cell.

[0004] Although the above-mentioned device can protect the terminals, the cover and the two terminal slots in the device are an integral structure, making it difficult to adapt to terminals of different battery cell models. Furthermore, it is difficult to lead out the terminal outlet wires during the protection process.

[0005] In summary, protecting the terminals of different battery cell models and facilitating the lead-out of terminal wires are urgent problems that need to be solved. Utility Model Content

[0006] The purpose of this invention is to provide a protective structure for square battery cell terminals to solve the aforementioned problems in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A protective structure for a square battery cell terminal includes a square protective shell, which is fitted over the terminal at the upper end of the battery cell. A clamping plate is elastically slidable inside the square protective shell to clamp the terminal to the inner wall of one end of the square protective shell. A wire groove is provided on one side of the square protective shell to lead the terminal wire out of the square protective shell through the wire groove.

[0009] As a preferred technical solution of this utility model, the clamp is slidably connected between the inner walls of both sides of the square protective shell, and the side of the clamp facing the pole is elastically connected to the inner wall of one end of the square protective shell through at least two springs.

[0010] As a preferred technical solution of this utility model, a second rubber pad is installed on the side of the clamp facing the pole post and / or on the inner wall of one end of the square protective shell, and the second rubber pad is provided with a relief groove adapted to the spring.

[0011] As a preferred technical solution of this utility model, a first rubber pad is installed on the inner wall of the other side of the square protective shell, one side of the clamping plate is in contact with the surface of the first rubber pad, the other side of the clamping plate is in contact with the inner wall surface of one side of the square protective shell, and the upper end of the clamping plate is in contact with the inner top surface of the square protective shell.

[0012] As a preferred technical solution of this utility model, the top surface or the other end of the square protective shell is provided with an adjustment hole to facilitate the adjustment of the position of the clamping plate.

[0013] As a preferred technical solution of this utility model, the square protective shell is slidably connected to a push plate connected to a clamping plate, which is used to adjust the distance between the clamping plate and one end of the square protective shell.

[0014] As a preferred technical solution of this utility model, the adjustment hole is opened on the top surface of the square protective shell, the push plate is slidably connected to the upper end of the square protective shell, the clamping plate is connected to the push plate through the connecting plate, and the middle part of the connecting plate is slidably connected to the adjustment hole.

[0015] As a preferred technical solution of this utility model, all the springs are evenly distributed inside the square protective shells on both sides of the pole post.

[0016] Beneficial effects: This utility model has a wire groove on one side of the square protective shell, which facilitates the lead-out of the terminal wire during the protection of the pole. The square protective shell has a flexible sliding clamp inside, which cooperates with the inner wall of one end of the square protective shell to clamp the pole, ensuring the stability of the square protective shell and thus ensuring the protection effect. At the same time, since the clamp is flexible and slides inside the square protective shell, there is a certain amount of room for movement inside the square protective shell, which can stably fix the protective shell on poles of different models, and the installation process is very convenient.

[0024] Example:

[0025] like Figures 1-5 As shown, this embodiment provides a protective structure for a square battery cell terminal, including a square protective shell 2. The square protective shell 2 is sleeved on the terminal 8 at the upper end of the battery cell 1 to protect the terminal 8. A clamping plate 3 is elastically slidable inside the square protective shell 2 to clamp the terminal 8 with the inner wall of one end of the square protective shell 2. The clamping plate 3 can clamp the terminal 8 by elastically moving inside the square protective shell 2, thereby ensuring the stability of the square protective shell 2. At the same time, the clamping plate 3 can be adjusted to adapt to different models of battery cell terminals for protection. A wire groove 7 is opened on one side of the square protective shell 2 to lead the terminal wire out to the outside of the square protective shell 2. Of course, in practice, space will also be left inside the square protective shell 2 for the lead wire.

[0026] This invention features a wire groove 7 on one side of a square protective shell 2. This allows for easy routing of the terminal wires from the pole 8 during protection. An elastically sliding clamp 3 is located inside the square protective shell 2. The clamp 3 engages with the inner wall of one end of the square protective shell 2 to clamp the pole 8, ensuring the stability of the square protective shell 2 and thus guaranteeing the protective effect. Because the clamp 3 is elastically sliding within the square protective shell 2, it provides a certain amount of space for movement, allowing the protective shell 2 to be stably fixed to poles 8 of different models. The installation process is also very convenient.

[0027] As a preferred embodiment of this example, it should be further explained that the clamping plate 3 is slidably connected between the inner walls on both sides of the square protective shell 2. The side of the clamping plate 3 facing the pole post 8 is elastically connected to the inner wall of one end of the square protective shell 2 through at least two springs 4. Thus, the distance between the clamping plate 3 and the inner wall of one end of the square protective shell 2 can be adjusted by the springs 4. While clamping the pole post 8, it can be adapted to different models of pole posts 8. The structure is simple and the operation is convenient.

[0028] As a preferred embodiment of this example, it should be further explained that a second rubber pad 10 is installed on the side of the clamping plate 3 facing the pole post 8 and / or on the inner wall of one end of the square protective shell 2. The second rubber pad 10 can ensure the clamping effect while avoiding damage to the equipment. The second rubber pad 10 is provided with a relief groove that matches the spring 4 to ensure the stable connection of the spring 4.

[0029] As a preferred embodiment of this example, it should be further explained that a first rubber pad 9 is installed on the inner wall of the other side of the square protective shell 2. In practice, one side of the pole post 8 can contact the first rubber pad 9 to position the square protective shell 2. The first rubber pad 9 also protects the damaged equipment. In addition, it can also leave an appropriate space between the other side of the pole post 8 and the wire groove 7 for wire routing. One side of the clamping plate 3 contacts the surface of the first rubber pad 9, and the other side of the clamping plate 3 contacts the inner wall surface of one side of the square protective shell 2. The upper end of the clamping plate contacts the inner top surface of the square protective shell 2 to ensure the stability of the clamping plate 3 when sliding.

[0030] As a preferred embodiment of this example, it should be further explained that the top surface or the other end of the square protective shell 2 is provided with an adjustment hole to facilitate the adjustment of the position of the clamping plate 3. Through the adjustment hole, the position of the clamping plate 3 can be adjusted by hand or with the help of other equipment, thereby making the adjustment of the clamping plate 3 more convenient.

[0031] As a preferred embodiment of this example, it should be further explained that the square protective shell 2 is slidably connected to a push plate 6 connected to the clamping plate 3, which is used to adjust the distance between the clamping plate 3 and one end of the square protective shell 2. Thus, the position of the clamping plate 3 can be directly adjusted by moving the push plate 6, making the adjustment of the clamping plate 3 more convenient.

[0032] As a preferred embodiment of this example, it should be further explained that the adjustment hole is opened on the top surface of the square protective shell 2, the push plate 6 is slidably connected to the upper end of the square protective shell 2, the clamping plate 3 is connected to the push plate 6 through the connecting plate 5, and the middle part of the connecting plate 5 is slidably connected to the adjustment hole, thereby making the control of the clamping plate 3 by the push plate 6 more convenient and stable.

[0033] As a preferred embodiment of this invention, it should be further explained that all the springs 4 are evenly distributed inside the square protective shells 2 on both sides of the pole post 8, which can more stably ensure the stability of the clamping plate 3 when it slides.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
