Technical Field

[0001] This utility model patent relates to the technical field of batteries, specifically to a split-type terminal structure and battery with high overcurrent capability. Background Technology

[0002] Currently, the cover plate of new energy power batteries is equipped with a bipolar structure. When the other components assembled with the poles remain unchanged, in order to increase the charge flow, that is, to increase the current, the cross-sectional area of ​​the poles needs to be increased. However, if the cross-sectional area of ​​the poles is simply increased, the current carrying capacity of the pole structure is greatly limited by the width of the cover plate.

[0003] In addition, the design of the bipolar structure has higher requirements for flatness, and has the disadvantages of complex structure, low assembly efficiency and high cost. Furthermore, after the individual cells are assembled, the welding of the bipolar structure to the connecting bar will increase the material cost. Utility Model Content

[0030] Reference Figure 1-4 The image shown is a preferred embodiment of the present invention.

[0031] The high current-carrying capacity split pole structure includes a top cover plate 200, an upper pole and a lower pole 303. The lower pole 303 passes through the top cover plate 200 and has a base plate 304 at its bottom, which is located below the top cover plate 200. The upper pole and the lower pole 303 are connected to form a pole. The upper part of the upper pole has an upper section 301 exposed above the top cover plate 200.

[0032] The high current-carrying capacity split-type pole structure described above has the following advantages:

[0033] 1) The upper column and the lower column 303 are connected to form the pole column, which is arranged in a split manner. The upper column has an upper section 301 exposed above the top cover plate 200. By increasing the size of the upper section 301, the cross-sectional area of ​​the pole column can be increased, which greatly enhances the current carrying capacity of the pole column structure.

[0034] 2) The single pole arrangement simplifies the structure, reduces installation steps, and improves assembly efficiency;

[0035] 3) The single pole arrangement simplifies the card layout and makes it easier to control.

[0036] In this embodiment, the upper segment 301 is preferably elliptical in shape. This way, while keeping the width of the upper segment 301 unchanged, the cross-sectional area of ​​the pole can be increased by increasing the length of the upper segment 301, thereby greatly enhancing the current carrying capacity of the pole.

[0037] In this embodiment, the top cover 200 is provided with an upper plastic part 100, and the upper section 301 abuts against the upper plastic part 100 from top to bottom. This facilitates the positioning and arrangement of the upper section 301 and facilitates the connection between the upper section 301 and the external connecting strip.

[0038] In this embodiment, the upper segment 301 is elliptical. This allows for an increase in the cross-sectional area of ​​the upper segment 301 by increasing its length without increasing its width.

[0039] In this embodiment, conductive adhesive is provided between the upper segment 301 and the lower column 303 to facilitate conductive connection between the upper segment 301 and the lower column 303, eliminating the direct connection gap between the two.

[0040] Alternatively, the bottom of the upper segment 301 may have a protruding locking post 3011, and the lower column 303 may have a locking groove 3031. The locking post 3011 is embedded in the locking groove 3031, and the locking groove 3031 is filled with conductive adhesive. This facilitates the connection between the upper column and the lower column 303. The locking groove 3031 can be filled with conductive adhesive first. After the locking post 3011 is embedded in the locking groove 3031, the conductive adhesive overflows between the upper segment 301 and the lower column 303, filling the gap between them.

[0041] Alternatively, the bottom of the upper section 301 may be provided with a protruding post 302, and conductive adhesive may be provided between the bottom of the protruding post 302 and the top of the lower post 303, which facilitates the docking connection between the upper post and the lower post 303.

[0042] The protruding post 302 passes through the upper plastic part 100, and the upper plastic part 100 wraps around the outer periphery of the protruding post 302, which can guide and position the installation of the protruding post 302.

[0043] In this embodiment, the upper plastic part 100 is provided with a mounting hole 101, and the protrusion 302 passes through the mounting hole 101. The outer periphery of the protrusion 302 is provided with outer serrations 3021, and the inner sidewall of the mounting hole 101 is provided with inner serrations 102. The outer serrations 3021 and the inner serrations 102 are fixedly engaged. During the installation process, external pressure is applied manually to make the protrusion 302 embedded in the mounting hole 101, and the outer serrations 3021 and the inner serrations 102 are directly engaged and connected, without the need for additional machine operation, thus reducing mechanical costs. In addition, the engagement between the outer serrations 3021 and the inner serrations 102 can increase the tensile strength between the protrusion 302 and the upper plastic part 100.

[0044] In this embodiment, a lower plastic part 400 is provided below the top cover plate 200, and the bottom plate 304 abuts against the lower plastic part 400 from bottom to top. In this way, the lower plastic part 400 is clamped between the top cover plate 200 and the bottom plate 304, and the fit is stable.

[0045] In this embodiment, the upper column and the lower column 303 can be in the shape of an elliptical cylinder. In this way, after the upper column and the lower column 303 are combined with the top cover plate 200, the upper plastic part 100 and the lower plastic part 400, it is easier to eliminate circumferential rotation.

[0046] This embodiment also provides a battery, including the aforementioned high-current-capacity split-type terminal structure, which has the following advantages:

[0047] 1) Customizable current-carrying contact area to increase current-carrying capacity;

[0048] 2) Easy to assemble, reducing machine costs;

[0049] 3) Improve the production qualification rate and reliability of batteries.

[0050] 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.
