📌 Product Overview

The Global Standard for Heavy-Duty Towing.

Reliable lighting is crucial for road safety. Victory Technology’s 7-Pin Metal Trailer Connectors are engineered to the rigorous ISO 1185 (Type N) and ISO 3731 (Type S) standards, ensuring universal compatibility with European trucks, agricultural machinery, and global commercial fleets.

Manufactured in our Zhuji Aoke facility, these connectors feature rugged Die-Cast Zinc Alloy Housings that far outperform plastic alternatives in durability. Whether used on a farm tractor or a long-haul semi-trailer, the solid metal construction resists impact, vibration, and corrosion.

  • The Victory Standard: We use high-conductivity Brass Terminals to ensure a stable electrical connection for lights and auxiliary power, eliminating voltage drop.


🔹 Why Choose Victory Metal Connectors?

  • ✅ Indestructible Zinc Alloy Housing:

    Built for the long haul. The heavy-duty die-cast metal shell protects the internal wiring from crushing forces and road debris. It is naturally resistant to rust and weathering.

  • ✅ ISO Standard Compliance (Round Pin):

    Designed for global fleets. Fully compliant with ISO 1185 (Normal – Black) and ISO 3731 (Supplementary – White) standards featuring the standard 7-Pin Round configuration. Ideal for 12V and 24V systems.

  • ✅ Weather-Proof Design:

    The socket features a strong spring-loaded metal lid with a rubber gasket. It snaps shut automatically when disconnected, sealing out dust, rain, and mud to prevent terminal corrosion.

  • ✅ Secure Cable Clamp:

    The plug includes a heavy-duty rear cable clamp (strain relief) that grips the cable jacket firmly, preventing the wires from being pulled out of the terminals during vehicle movement.
