[0023] In combination with Figures 1-5 A capacitor packaging box, comprising a first packaging cavity box 1 and a second packaging cavity box 2 arranged on one side of the first packaging cavity box 1, the first packaging cavity box 1 and the second packaging cavity box 2 are clamped and connected, the inner surfaces of the first packaging cavity box 1 and the second packaging cavity box 2 are uniformly distributed with a discharge coating 3, the discharge coating 3 comprises a glue layer 31 and a metal powder layer 32; the first packaging cavity box 1 comprises an upper transparent cavity box 11, the upper transparent cavity box 11 is provided with a hollow groove 12 on the upper and lower sides, and the upper transparent cavity box 11 is provided with a strip groove 13 on the left and right sides; the second packaging cavity box 2 comprises a lower transparent cavity box 21, the upper transparent cavity box 11 is uniformly distributed with a recess 14 on one side, and the lower transparent cavity box 21 is uniformly distributed with a receiving cavity 24 on one side, the recess 14 and the corresponding receiving cavity 24 are matched with each other.

[0024] The present application will be further described in combination with the embodiments. Embodiment

[0025] The lower transparent cavity box 21 is provided with a first clamping plate 22 on the upper and lower sides, and the two groups of first clamping plates 22 are matched with the two groups of hollow grooves 12, respectively.

[0026] The lower transparent cavity box 21 is provided with a second clamping plate 23 on the left and right sides, and the two groups of second clamping plates 23 are matched with the two groups of strip grooves 13, respectively.

[0027] The inner walls of each group of recesses 14 and each group of receiving cavities 24 are provided with a buffer protrusion, and the buffer protrusion is a component made of elastic rubber.

[0028] The shapes of the recesses 14 and the receiving cavities 24 are matched with the shapes of the capacitors to be packaged.

[0029] The first packaging cavity box 1 and the second packaging cavity box 2 are components made of PS.

[0030] In summary, the core structure of this utility model's PS material capacitor packaging box assembly with discharge coating 3 is a box made of PS material. PS material has good formability and cost advantages, and compared with traditional foam materials, it can significantly reduce the cost of basic materials. After each group of capacitors is embedded in the storage chamber 24, the buffer protrusion is tightly attached to the capacitor shell to form a flexible fixation. The discharge coating 3 is in natural contact with the capacitor electrode shell, establishing a static dissipation channel to ensure the stability of the overall structure. After each group of storage chambers 24 has stored all the capacitors, the upper transparent cavity box 11 is snapped and fixed on one side of the lower transparent cavity box 21. The first locking plate 22 is snapped and fixed into the empty groove 12, and the second locking plate 23 is snapped and fixed into the inside of the groove 13. Each set of grooves 14 corresponds to a capacitor, and the grooves 14 and the storage chambers 24 cooperate to position a set of capacitors. The PS box body resists external impacts, the receiving grooves isolate individual capacitors to avoid collisions, and the buffer protrusions absorb vibration energy. The discharge coating 3 applied to the inner surface of the box can replace the traditional discharge foil to achieve discharge and anti-static functions, ensuring the safety of capacitor storage and transportation. The discharge coating 3 is made by mixing an adhesive layer 31 and a metal powder layer 32. The adhesive layer 31 uses acrylic adhesive, while the metal powder layer 32 uses a mixture of metal powder and carbon black filler. The mixture of adhesive layer 31 and metal powder layer 32 forms a continuous conductive path to achieve static discharge. The discharge coating 3 has good wear resistance and stable discharge effect, making the packaging box balance cost and discharge stability. During production, the PS box body can be formed by injection molding according to the sample provided by the customer, and then the inner surface of the box body is coated with discharge coating 3. This process is simple and easy to operate, which is convenient for large-scale production. At the same time, it eliminates the multi-layer assembly process of the traditional foam plus discharge foil structure, further reducing production and assembly costs. Compared with the traditional two-layer foam plus discharge foil packaging structure, this utility model simplifies the structure and production process through the integrated PS box body plus discharge coating 3 design. It also takes advantage of the cost of PS material to achieve a significant reduction in packaging costs, while effectively ensuring the safety performance of capacitor packaging.
