[0027] Please refer to Figures 1 to 4 The utility model proposes a single-cell aging fixture. A preferred embodiment of the single-cell aging fixture of the utility model includes a base 1 and a mounting seat 2 vertically arranged on the base 1, two brackets 3 are oppositely arranged on both sides of the mounting seat 2 on the base 1, and slide rails 4 are arranged on the two brackets 3. Slide rails 4 are slidably arranged on the slide rails 4. A fixture 6 connected to the slide 5 is arranged on the base 1, and two groups of first copper terminal assemblies are arranged at the bottom of the slide 5. The first copper terminal assembly includes a first copper terminal 7 and a second copper terminal 8 located below the first copper terminal 7.

[0028] Specifically, in this embodiment, the two groups of first copper terminals 7 are arranged on both sides of the bottom of the slider 5. When performing a cell aging test, the height of the slider 5 is adjusted by the clamp 6, and then the two first copper terminals 7 can be flexibly adjusted to correspond to the height of the cell, thereby meeting the testing requirements of various types of cells.

[0029] The size and space of each part of the base 1, the mounting seat 2, the bracket 3 and the two groups of first copper terminal assemblies are just right and can be applied to various types of battery cells.

[0030] In this embodiment, the base 1, the mounting base 2 and the bracket 3 are all made of bakelite, which is both insulating and strong.

[0031] The entire mounting base 2 and the bracket 3 adopt a bakelite frame design, which not only improves the overall toughness, but also integrates beauty and strength, while also highlighting the beauty of the terminal metal and improving the aesthetics.

[0032] Furthermore, in this embodiment, a first fine-tuning knob 9 for adjusting the pressure of the first copper terminal 7 is provided on the slider 5 .

[0033] When testing the battery cell, the first copper terminal 7 can be fine-tuned by rotating the first fine-tuning knob 9, so that the contact between the second copper terminal 8 and the positive and negative electrodes of the battery cell can be well adjusted to improve the conductivity of the battery pack.

[0034] Furthermore, in this embodiment, a slot 10 is provided on the sliding block 5 , and the first copper terminal 7 is clamped in the slot 10 .

[0035] The first copper terminal 7 is connected to the slider 5 via a screw 11 .

[0036] Furthermore, in the present embodiment, two groups of second copper terminal assemblies are arranged on the base 1 , and the second copper terminal assemblies include a third copper terminal 12 and a fourth copper terminal 13 located below the third copper terminal 12 .

[0037] The third copper terminal 12 is provided with a second fine-tuning knob 14 .

[0038] In this embodiment, the second copper terminal assembly can be used to test smaller battery cells. By rotating the second fine-tuning knob 14, the third copper terminal 12 can be fine-tuned, thereby effectively demodulating the contact between the fourth copper terminal 13 and the positive and negative electrodes of the battery cell, thereby improving the conductivity of the battery pack.

[0039] Furthermore, in this embodiment, the material of the first copper terminal assembly and the second copper terminal assembly is red copper.

[0040] Specifically, in this embodiment, the first copper terminal assembly and the second copper terminal assembly use a combination of two positive and two negative terminals made of red copper, which fully considers the conductivity of large currents, the installation or removal of external wires, and the reliability of the battery cell during installation. Inside the terminal body, a metal copper integrated structure is adopted, so that the terminal can withstand a larger current, fully improving the safety performance and current carrying capacity, without worrying about the terminal problem causing rapid heating or the occurrence of safety accidents. The metal surface adopts a gold-plating process, and the beauty of the light metal refraction plus the sense of power of the appearance make it more atmospheric.
