Description

Technical Field

[0001] This utility model relates to the field of liquid-cooled battery packs, specifically a connector for high-protection-level battery packs. Background Technology

[0002] With the continuous advancement of energy storage technology, the market demand for high energy density is increasing. Large-capacity liquid-cooled battery packs are gradually replacing traditional small-capacity air-cooled battery packs, becoming the mainstream choice for energy storage systems, especially in large-scale energy storage projects. The application of liquid cooling technology not only improves the energy density and charge / discharge efficiency of the battery but also significantly enhances its temperature control capabilities, effectively extending its service life. However, due to the large internal temperature difference during operation, condensation can easily form inside the battery pack, posing a potential threat to the electronic components within. Therefore, to ensure the safety and reliability of the battery pack, its protection rating must reach IP67 or higher.

[0003] While existing connectors can achieve IP67 protection standards, some shortcomings have been revealed in practical applications. First, to achieve a high protection level, connectors typically require external bolts to be secured to rivet nuts installed in blind holes pre-drilled in the metal panel. This installation method places extremely high demands on the manufacturing process, increasing production costs. Second, the connection between the blind hole and the rivet nut may have poor sealing, leading to gas leakage and affecting the overall protection performance of the battery pack. Finally, insufficient electrical clearance between the tail of the rivet nut and the conductive copper busbar of the connector may cause short circuits and other safety issues, threatening the safe operation of the battery pack.

[0004] To address the aforementioned issues, it is particularly necessary to design a connector for battery packs with a high level of protection. Utility Model Content

[0005] The purpose of this invention is to provide a connector for a high-protection-level battery pack to solve the technical problems mentioned in the background section.

[0006] The technical solution to achieve the purpose of this utility model is:

[0007] A connector for a high-protection-level battery pack includes a plug, conductive terminals, and a support connector. The support connector is coaxially sleeved on one end of the plug, and the conductive terminals pass through the support connector and are electrically connected to the plug. The support connector includes a support plate and a first slot and a second slot disposed on the support plate. The support plate is integrally formed with the first slot and the second slot. The first slot cooperates with one end of the plug, and the plug is inserted into the first slot. The second slot cooperates with an external connector to lock the high-protection-level battery pack connector onto an external sealing shell.

[0008] Furthermore, the first slot is coaxially disposed at the center of the support plate.

[0009] Furthermore, the second slot is provided in multiple ways, and the multiple second slots are evenly distributed circumferentially around the first slot on the support plate.

[0010] Furthermore, the external connector is a bolt, and the inner surface of the second slot is provided with threads that mate with the threads of the bolt, so that the high-protection-level battery pack is secured to the external sealing housing by a connector.

[0011] Furthermore, the external connector includes a bolt and an embedded nut that engages with the bolt, the embedded nut being inserted into a second slot and having an interference fit with the second slot.

[0012] Furthermore, the conductive terminal adopts a square, sheet-like metal pin structure.

[0013] Furthermore, the metal pins are made of copper.

[0014] Furthermore, the support plate is a plastic support plate.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects:

[0016] (1) This utility model uses a second slot integrally formed with the support plate to cooperate with the external connector to lock the high protection level battery pack onto the external sealing shell, thereby avoiding the possible sealing problems between the blind hole and the press nut, and effectively ensuring the overall protection performance of the battery pack.

[0017] (2) The first slot for inserting the connector is coaxially set in the center of the support plate, which can ensure that the force it receives is evenly distributed when the connector is inserted, thereby reducing the risk of deformation or damage caused by asymmetrical force.

[0018] (3) The present invention has multiple second slots, which are evenly distributed around the first slot on the support plate in the circumferential direction. When connected, multiple points are locked to securely attach the high-protection-level battery pack connector to the external sealing shell.

[0019] (4) The conductive terminal of this utility model adopts a square sheet structure of metal pins, which provides good electrical contact performance, increases the stability of the structure, and reduces the problem of poor contact caused by vibration or impact.

[0020] (5) The metal pins of this utility model are made of copper. Copper pins have excellent electrical and thermal conductivity, which can ensure the stability and low resistance characteristics of the connector during high current transmission.

[0021] (6) The support plate of this utility model is a plastic support plate, which can effectively reduce the overall weight of the connector, while having good insulation performance and corrosion resistance, ensuring the reliability and safety of the connector in harsh environments; during the manufacturing process, the plastic support plate and the shell are easier to integrally mold, resulting in lower costs.
