[0027] Refer to Figures 1-5 As shown, it is a preferred embodiment provided by the present utility model.

[0028] The battery pole structure includes a pole plate 200 and a plurality of pole bodies 100 fixedly arranged on the pole plate 200. The polarities of the plurality of pole bodies 100 are the same, and the plurality of pole bodies 100 are arranged at intervals.

[0029] In the battery pole structure provided above, a plurality of pole bodies 100 are arranged on the pole plate 200. The plurality of pole bodies 100 maintain the same polarity and are arranged at intervals. In this way, under the condition of limited space for the width of the battery top cover, a structure with multiple pole bodies 100 can be realized, meeting the over-current capacity of the battery, and the structure is simple.

[0030] The pole plate 200 has a pole hole 201. The lower part of the pole body 100 forms a fitting part that penetrates through the pole hole 201. The upper part of the pole body 100 extends outward relative to the pole plate 200 to form an extension section, and this extension section extends outward through the top cover piece and is connected to the upper pole block on the top cover piece.

[0031] The outer periphery of the fitting part protrudes outward to form an outer convex ring 101, and the inner side wall of the pole hole 201 is recessed outward to form an upper groove ring 202. The outer convex ring 101 is placed in the upper groove ring 202, and the pole body 100 is fixedly connected to the pole plate 200.

[0032] The fitting part of the pole body 100 penetrates through the pole hole 201. The outer convex ring 101 formed on the fitting part cooperates with the upper groove ring 202 to realize the axial positioning and circumferential positioning between the pole body 100 and the pole plate 200, facilitating the assembly between the pole body 100 and the pole plate 200, and the structure is simple.

[0033] In some embodiments, the pole column body 100 and the pole column plate 200 can be formed by stamping / extrusion respectively. The pole column body 100 and the pole column plate 200 can be made of the same material or different materials.

[0034] The top of the outer convex ring 101 has a lower mating step 104, and the top of the upper groove ring 202 has an upper mating step 204. The upper mating step 204 abuts against the lower mating step 104. After the outer convex ring 101 is placed in the upper groove ring 202, the upper mating step 204 and the lower mating step 104 are in an up-and-down abutting fit to axially position the pole column body 100.

[0035] The outer periphery of the outer convex ring 101 abuts against the inner side wall of the upper groove ring 202 to form a circumferentially arranged mating surface 400. The mating surface 400 is fixedly connected, and the circumferential positioning of the pole column body 100 is realized through the surface abutting fit of the mating surface 400.

[0036] In some embodiments, the mating surface 400 is fixedly connected by welding. In this way, the connection between the pole column body 100 and the pole column plate 200 can be made firm, and the fixed connection operation is convenient.

[0037] In some embodiments, the inner side wall of the pole column hole 201 is recessed outward to form a lower groove ring 203. An annular clearance ring position 300 is formed between the lower groove ring 203 and the pole column body 100, and the mating surface 400 is arranged on one side of the clearance ring position 300.

[0038] By forming the clearance ring position 300, it is convenient to perform the welding operation on the mating surface 400, and it is avoided that the height of the welding affects the connection between the pole column plate 200 and the connecting piece.

[0039] In some embodiments, the bottom of the mating portion extends to the outside of the pole column plate 200 to form a positioning table stage 102 for positioning connection with the connecting piece. In this way, when the pole column plate 200 and the connecting piece are welded and connected, through the positioning table stage 102, it is convenient for accurate positioning during the welding operation.

[0040] Alternatively, the bottom of the mating portion is flush with the bottom of the pole column plate 200, which can be determined according to actual needs.

[0041] In some embodiments, the outer periphery of the extension section contracts inward to form a fusing section 103. When the charging and discharging current is too large, the fusing section 103 can fuse by itself to disconnect the electrical circuit and play a protective role.

[0042] Specifically, along the axial direction of the extension section, the fusing section 103 is formed in the middle of the extension section. In this way, it is convenient for the formation of the fusing section 103, and the fusing section 103 is spaced from the pole column plate 200, so that the fusing section 103 can act as an independent part to play a fusing protection role.

[0043] In some embodiments, the terminal body 100 and the terminal plate 200 are integrally formed. In this way, the terminal body 100 and the terminal plate 200 form a complete and integrated whole, with a stable structure, better overall strength, and no need for operations such as assembly.

[0044] This embodiment also provides a battery, which includes the above-mentioned battery terminal structure. The assembly between the terminal body 100 and the terminal plate 200 is convenient, and the structure is simple, greatly improving the production efficiency of the battery and simplifying the battery structure.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
