Leading PVC Dipping Insulated Battery Busbar Connector Manufacturer
As a leading manufacturer of PVC Dipping Insulated Battery Busbar Connectors, we provide high-quality solutions tailored for superior electrical conductivity, enhanced safety, and reliable performance in various battery applications. Our connectors are crafted using premium copper and robust PVC insulation, ensuring long-lasting durability and efficient power distribution.
Production process:
- Pre-treatment: Copper rows are acid washed and alkaline washed to remove oil and oxidized layer to ensure a clean surface.
- Heating: Preheat the copper rows to 180℃-250℃, so that the PVC powder adheres evenly.
- Plastic dipping: Copper row immersed in PVC sol fluidized bed, control the thickness of insulation layer by dipping several times (usually 2-3 times).
- Curing: Curing: Plasticize in hot air circulating furnace at 160℃-200℃ to form a dense insulating layer.
- Post-treatment: After cooling and shaping, the excess insulation layer is removed and the electrical properties are tested.

PVC Dipping Insulated Battery Busbar Connector Designs:
1.Shaped integrated structure:
- Characteristics: Adopting the overall bending or stamping process, the main body of the connecting bridge and the bending part (e.g., Z-shaped, L-shaped) are integrated and molded, avoiding the redundancy of sub-parts caused by traditional welding or splicing. For example, fastening planes, extension arms and other structures are formed by bending copper strips, which are directly embedded inside the battery pack, reducing the assembly process.
- Advantages: Reduced processing costs improved mechanical strength (increased vibration resistance), suitable for complex spatial layouts
2. Modular splicing design:
- Features: Tabs and grooves or lug guiding pins on both sides of the connector support splicing and expansion of multiple connectors to adapt to different current capacity requirements. For example, energy storage system bus ducts can be flexibly expanded through modular splicing.
- Advantage: Enhance system integration and reduce customization costs, while ensuring stability after splicing through standardized interfaces.
PVC Dipping Insulated Battery Busbar Connector Insulation Type:
Standard PVC Insulated
General-purpose busbars with basic PVC insulation for typical applications.
High-Temperature PVC Insulated
Features PVC insulation rated for higher temperatures, suitable for demanding environments.
Chemical-Resistant PVC Insulated
Equipped with a PVC coating that resists exposure to specific chemicals, ideal for harsh industrial conditions.
PVC Dipping Insulated Battery Busbar Connector Connection Type:
1.Plug-in design
Characteristics: Plug and socket mating structure, easy plugging and unplugging and low contact resistance (usually ≤ 0.5mΩ). For example, the precision mating design of plug base and socket base is suitable for high-frequency maintenance scenarios .
Advantage: Quick installation and high compatibility, especially suitable for portable equipment or dynamic connection needs.
2.Bolt-on design
Features: High current-carrying (200A-3000A) and vibration-resistant performance is achieved through bolts crimping the contact surface of copper rows, combined with localized openings in the insulation protection layer. For example, the power battery packs of new energy vehicles are fastened with bolts to ensure the stability of high current transmission.
Advantage: solid connection, high current impact resistance, suitable for industrial distribution cabinets and other high-reliability scenarios.
