Product Introduction: Waterproof Piercing Automotive Battery Cable & Board Connector

Ensure a secure, weatherproof, and corrosion-resistant power connection in your vehicle's electrical system with our specialized Waterproof Piercing Automotive Battery Cable. This solution integrates a heavy-duty battery cable with a innovative piercing connector, designed to create a reliable, sealed tap directly into existing wiring or connection boards without the need for cutting or stripping the main wire.

Key Features & Benefits:

• Waterproof & Sealed Connection: The integrated piercing connector features a robust rubber seal and waterproof housing (typically rated IP67 or higher). Once installed and tightened, it forms a complete barrier against moisture, dirt, and road chemicals, preventing corrosion and electrical failure.

• Simplified, Non-Destructive Installation: The built-in piercing terminal cleanly penetrates the insulation of a main power wire (e.g., from the battery) to make contact with the conductor inside. This allows for a secure power tap without cutting, splicing, or soldering the original cable, preserving its integrity and saving significant installation time.

• Heavy-Duty Battery Cable: Constructed with high-purity, fine-strand copper wire and a thick, flexible insulation jacket (often PVC or EPDM). It is engineered to handle high starting currents and continuous loads from auxiliary lights, audio systems, winches, or other accessories.

• Secure Connection to Boards & Strips: The opposite end of the cable is typically terminated with a standard ring terminal or post connector, allowing for a solid, bolted connection to fuse blocks, distribution boards, bus bars, or the battery terminal itself.

• Enhanced Safety & Reliability: By maintaining a sealed and mechanically secure connection, this system eliminates loose connections, exposed wires, and corrosion points—common causes of voltage drop, overheating, and electrical faults in automotive environments.

Primary Applications:

• Adding auxiliary circuits (lights, air compressors, inverters) with a clean tap from the main battery cable.

• Connecting to aftermarket fuse boxes or power distribution units (PDUs).

• Creating secure, waterproof power branches in off-road, marine, or RV electrical systems.

• Repairing or extending existing battery cables with a sealed, professional connection.

Typical Specifications & Notes:

• Cable Gauge: Common sizes: 4 AWG, 8 AWG (for high-current applications)

• Piercing Connector: Insulation-piercing, screw-down clamp with integrated seal

• Waterproof Rating: IP67 (Immersion up to 1m for 30 min)

• Temperature Range: -40°C to +105°C (for standard PVC)

• Important: Ensure the piercing connector is rated for the combined current of all connected circuits. Always install with the correct torque and verify the seal is properly compressed around the host wire.
