[0031] Reference Figure 1-3 The image shown is a preferred embodiment of the present invention.

[0032] The detachable assembly pole structure includes a top cover plate 300, an upper pole section 201, and a lower pole section. The upper pole section 201 and the lower pole section are formed separately, meaning that the upper pole section 201 and the lower pole section are separate, and the upper pole section 201 and the lower pole section can be assembled together.

[0033] The lower section of the pole passes through the top cover plate 300 and has an upper portion 202 extending above the top cover plate 300. The upper section 201 of the pole is connected to the upper portion 202. The lower section of the pole has a lower portion located below the top cover plate 300. The upper section 201 of the pole and the lower section of the pole are connected to form a pole.

[0034] The aforementioned separate assembly pole structure has the following advantages:

[0035] 1) Compared with riveting and pressing processes, the upper part of the pole post 201 is formed separately and connected to form the pole post. The assembly technology is simple, the assembly efficiency is high, and the surface is undamaged.

[0036] 2) Compared with stamping and pressing processes, the upper section 201 of the pole post is connected to the lower section of the pole post to form the pole post, making it easier to ensure the quality of the pole post;

[0037] 3) Compared to integrated terminals, the separate assembly of terminals has a larger fault tolerance. When it is necessary to change the current carrying capacity, only the width or length of the upper section 201 of the terminal needs to be changed.

[0038] 4) The pole structure adopts a single pole arrangement, which makes it easier to control the flatness of the pole.

[0039] In this embodiment, the upper section 201 of the pole post is elliptical. In this way, while keeping the width of the upper section 201 of the pole post unchanged, the cross-sectional area of ​​the pole post can be increased by increasing the length of the upper section 201 of the pole post, which greatly improves the current carrying capacity of the pole post. In addition, the upper section 201 of the pole post can provide a welding position for the connecting bus.

[0040] In this embodiment, the top cover 300 is provided with an upper plastic part 100, the lower section of the pole passes through the upper plastic part 100, the upper plastic part 100 has a top surface facing upward, and the bottom of the upper section 201 of the pole has a bottom surface, which abuts against the top surface from top to bottom. In this way, the upper section 201 of the pole abuts against the top surface of the upper plastic part 100, which facilitates the positioning of the upper section 201 of the pole, and the upper section 201 of the pole can be stably connected to the upper part 202.

[0041] In this embodiment, the upper section 201 of the electrode post is ring-shaped and is arranged around the outer periphery of the upper part 202 to facilitate the connection between the upper part 202 and the upper section 201 of the electrode post. A groove 2041 and a groove 2041 ring 301 are provided on the top surface, and an upper protruding ring is provided on the bottom surface, which is embedded in the groove 2041 and groove 2041 ring 301. The top and bottom surfaces are engaged through the upper protruding ring and the groove 2041 and groove 2041 ring 301, enhancing the torque between the electrode post and the upper plastic part 100 and providing anti-torsion protection for the electrode post.

[0042] In this embodiment, the upper section 201 of the pole post has a hollow hole 2011, and the upper part 202 passes through the hollow hole 2011 and is connected to the upper section 201 of the pole post as a whole. The upper part 202 passes through the hollow hole 2011 to facilitate the cooperation between the upper part 202 and the upper section 201 of the pole post.

[0043] In this embodiment, the lower section of the pole includes a base plate 204 and a column 203. The base plate 204 forms the lower part described above, and the lower part of the column 203 is attached to the base plate 204. The base plate 204 is located below the top cover plate 300, and the column 203 passes through the top cover plate 300. The upper part of the column 203 extends above the top cover plate 300, forming the upper part 202 described above.

[0044] Thus, the pole post is divided into an upper pole post section 201, a column body 203, and a base plate 204. The upper pole post section 201, the column body 203, and the base plate 204 are separately formed, that is, separately arranged. When the three are assembled together, they form a pole post.

[0045] The base plate 204 and the column 203 can be formed separately, or the base plate 204 and the column 203 can be formed as one piece, depending on the actual needs.

[0046] In this embodiment, the base plate 204 is provided with a groove 2041 with a top opening, and the lower part of the column 203 is embedded in the groove 2041 and connected to the base plate 204 as a whole. In this way, the column 203 can withstand more lateral or longitudinal thrust, making the pole column structure more stable.

[0047] After the lower part of the column 203 is embedded in the groove 2041, the lower part of the main body is welded to the inner wall or bottom of the groove 2041, which can increase the welding connection area between the column 203 and the base plate 204, making the connection between the column 203 and the base plate 204 more secure.

[0048] The connection is made by welding on the inner wall or bottom of the groove 2041, eliminating the need for welding on the surface of the base plate 204. This increases the welding surface area, making the connection between the column 203 and the base plate 204 more secure, reducing the damage to other components caused by rough weld joints, and ensuring the quality of the pole column structure. Furthermore, the groove 2041 facilitates the installation and positioning of the column 203 and the base plate 204.

[0049] In this embodiment, a lower plastic part 400 is provided below the top cover 300, and the bottom plate 204 abuts against the lower plastic part 400 from bottom to top, which facilitates the positioning of the bottom plate 204.

[0050] In this embodiment, the outer periphery of the column 203 is wrapped with a sealing ring 500. The sealing ring 500 has a clamping part 501 that is clamped between the lower plastic part 400 and the top cover plate 300. A lower protruding ring 2042 is provided on the bottom plate 204. The lower protruding ring 2042 is arranged around the circumference of the column 203. The lower protruding ring 2042 presses the clamping part 501 from bottom to top and is embedded in the clamping part 501.

[0051] The lower protruding ring 2042 presses against the sealing ring 500, causing the sealing ring 500 to deform. This creates an engagement between the lower protruding ring 2042 and the sealing ring 500, greatly enhancing the sealing effect of the sealing ring 500.

[0052] In this embodiment, the method of bipolar posts / or multiple posts is eliminated. The upper section 201 of the post, the post body 203 and the base plate 204 are combined to form the post. The post body 203 and the upper section 201 of the post are elliptical or square in shape. The upper section 201 of the post and the post body 203, as well as the post body 203 and the base plate 204, are connected by welding.

[0053] This embodiment also provides a battery, including the above-described separate assembled terminal structure, which has the following advantages:

[0054] 1) By changing the dimensions of the upper section 201 of the electrode post, the current-carrying contact area can be customized to increase the current-carrying capacity;

[0055] 2) Reduced riveting process, simple and compact structure, and lower cost;

[0056] 3) Improve the production qualification rate and product reliability of batteries.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
