[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example

[0026] Reference Figures 1 to 3 This embodiment of the present invention provides a nano-injection molded new energy battery terminal, including a base 100 and a recess 200 provided on the upper part of the base 100. An extreme end 300 is provided in the recess 200. A slot 101 is provided on the recess 200. A plurality of dispersed locking blocks 102 are provided in the slot 101. An insertion block 301 corresponding to the slot 101 is provided at the lower part of the extreme end 300. The insertion block 301 is provided with a slot 302 adapted to the locking block 102. The base 100 and the extreme end 300 are matched by the slot 101 and the insertion block 301 and are formed into a battery terminal by nano-injection molding. Unlike traditional battery terminals, this embodiment adds a locking block 102 and a slot 302 for interlocking with the slot 101 and the plug 301. The slot 101, plug 301, locking block 102 and slot 302 are all treated with nano-injection molding, which fills the gaps at the connection between the slot 101, plug 301, locking block 102 and slot 302, so that the base 100 is tightly connected to the terminal 300, and improves airtightness and pull-out resistance.

[0027] For example, such as Figure 2 As shown, the multiple locking blocks 102 are all toothed, and there are no fewer than three locking blocks 102, which are axially equidistantly arranged on the inner wall of the slot 101. When the locking blocks 102 are toothed and have three axially equidistantly arranged, the positions of the three locking blocks 102 form a triangle, and the triangle has stronger stability, making it less likely for the extreme 300 to separate from the base 100 due to lateral compression.

[0028] For example, such as Figure 3As shown, the slot 302 is located on the side wall of the insert block 301, and one end of the slot 302 extends out from the bottom of the insert block 301. Since the insert block 301 is on top and the slot 101 is on the bottom, in order for the insert block 301 to be properly inserted into the slot 101, one end of the slot 302 needs to protrude from the bottom of the insert block 301 to be properly inserted into the slot 102.

[0029] For example, such as Figure 3 As shown, the locking block 102 extends upward and protrudes from the upper end face of the base 100. The upper end of the locking groove 302 extends from the bottom of the extreme end 300 into its inner cavity, and the length of the locking groove 302 is the same as that of the locking block 102. Because the base 100 is a thin surface, the depth of the locking groove 302 provided therein is limited. In order to increase the degree of connection between the extreme end 300 and the base 100, the extension of the locking groove 302 into the extreme end 300 further increases the tightness of the connection between the base 100 and the extreme end 300.

[0030] For example, such as Figure 1-3 As shown, both the card slot 302 and the card block 102 have micro-protrusions on their surfaces. The formation of micro-protrusions can further increase the stability of the connection between the card slot 302 and the card block 102 to prevent extreme 300 torsion, thereby increasing stability. After nano-injection molding treatment, the connection between the two pairs of micro-protrusions can be further increased to improve the tensile strength of extreme 300.

[0031] The base 100 is made of copper.

[0032] The Extreme 300 is made of aluminum.
