GripSeal Quick Seal Connector: New Energy Battery Pack Airtightness Test Plugging Solution

After the battery pack case is assembled, Air tightness testIt is a key process to verify the sealing quality of the whole package. Before the test, all interfaces such as explosion-proof valve, charging port, communication port, coolant import and export on the shell need to be blocked, and then compressed air is filled into the shell through the reserved inflation port. The testing equipment monitors the pressure change and judges whether the sealing performance is up to standard. Timely interception of shell sealing defects can effectively prevent defective products from flowing into the next process.

According to the shape and sealing requirements of different nozzles, different types of pipes need to be selectedQuick seal jointIt takes into account plugging reliability, operational efficiency, and test safety.

The explosion-proof valve is a special interface on the battery pack shell, with many common models and obvious differences in appearance.GracieyouG20FSeries Quick Seal CouplingSpecially designed for explosion-proof valve plugging, using handle operation mode, align the explosion-proof valve bayonet and then fold the handle90°The connection can be completed. The connector body is made of aviation aluminum, which is light and durable; the built-in magnetic suction or suction cup structure can actively open the explosion-proof valve valve during connection to ensure that the test gas enters the inside of the shell smoothly, and the end sealing ring ensures the sealing reliability. Support customization of different explosion-proof valve models to match different bayonet sizes and opening methods.

Coolant import and export blockage:G70Series andG90series

The common nozzle forms for coolant import and export mainly include flange nozzles andVDAThere are two types of standard nozzles, and quick-sealing joints of different structures are recommended respectively.

Flange nozzles: recommended G70Series Quick Seal CouplingThe series adopts push-pull operation, and the connection can be completed by gently pushing the connector in hand.316The stainless steel main structure is strong, durable, and the end face sealing structure can withstand10BarStandard test pressure, suitable for air tightness testing and operation testing of cooling water channels. The connector has a safety marking ring, and there is a clear confirmation mark for the connection in place.

VDAStandard nozzles: recommendedG90L-NWSeries Quick Seal CouplingThis series adopts pressure rod operation, which uses the principle of lever to reduce the operating force. The main body is made of aluminum alloy, and the internal structure design can avoid damage to the surface of the nozzle. Sealing supportVDAThe original sealing ring inside the male head is realized, without additional consumption of sealing consumables, and the maintenance cost is low, which is suitable for high-frequency test scenarios.

Charging port, communication port, fast charging port and other connector interfaces, the interior is a pinhole or clip structure, and the inner wall tension sealing method is required.G25FSeries Quick Seal CouplingDrive the sealing ring radially to tighten through handle operation, and fit the inner wall of the interface to form a seal. According to the internal structure differences of the interface, this series is subdivided into high-current pinhole, high-current clip, probe and small-current clip versions, which can be adapted to different specifications of connector interfaces. The handle rotatable design is also easy to operate in a narrow space.

Air tightness testIt is a key checkpoint in the production process of battery packs, but it is not the end point. From shell assembly to helium detection, charge and discharge aging, different test stages have different emphasis on the requirements of sealed connections. GripSeal revolves aroundPACKThe full test cycle of the battery pack provides a quick-sealing joint solution that adapts to different nozzle shapes and test conditions. The purpose is only one: to make the test connection reliable and efficient enough to avoid becoming a bottleneck in the production line.
