SP Series Waterproof Connectors for Charging Pile Cable Bending

M8 Waterproof Connector Types and Specifications

Recommended Connector for Frequently Bent Charging Pile Cables

For charging piles where cables are frequently bent and connector breakage is a concern, the SP series waterproof connectors with flexible cables are recommended. These connectors are engineered to withstand repeated flexing and mechanical stress at the cable-to-connector junction.

Key Features for Bend Resistance

• TPU cable material: Resistant to ≥10,000 bends at a 10mm radius, providing long-term durability in high-flex applications.
• Integrated strain relief: A dedicated structure at the connector-cable junction prevents cable breakage caused by frequent bending.
• Application fit: Suitable for daily plugging/unplugging and cable storage scenarios typical of charging pile operations.

Why This Connector Suits Your Application

The primary failure mode in frequently bent charging cables is fatigue at the connection point. The SP series addresses this directly with its flexible TPU cable and reinforced strain relief, reducing the risk of intermittent contact or complete connector failure. This design supports reliable power and signal transmission over extended service life.

Selection Note

When specifying connectors for charging piles, confirm the required cable length, conductor gauge, and IP rating based on your installation environment. The bend resistance value applies to the cable itself under the stated test conditions; verify the complete assembly's performance for your specific routing and strain requirements.
