"2V2" refers to a specific contact layout code for D-Sub hybrid (Combo) connectors. Unlike traditional pure signal interfaces like DB9 or DB25, the 2 pin female connector is configured within a standard D-Sub housing size (typically shell size "1 DE/E") with only two high-current power terminals, omitting standard signal pins.
The core philosophy of this design is "simplification"—dedicating the entire structural space to power transmission. The ip67 waterproof connector is available in both Male (Plug) and Female (Socket) genders, supporting wire-to-wire or wire-to-board connections.
II. Core Advantages: High Current & IP67 Waterproofing
1. Powerful High-Current Carrying Capacity
Designed specifically for power transmission, the 2 pin male connector typically features a rated current per pin ranging from 10A to 40A. Some high-end models can even exceed 40A, making them perfectly suited for:
Direct Device Charging: Delivering power directly to industrial equipment like AGVs and robots.
Power Distribution: Serving as high-current interconnects between modules inside control cabinets.
New Energy Equipment: Power interfaces for charging piles and energy storage systems.
2. IP67 Waterproof & Dustproof Rating
Through precision sealing design, the 2V2 waterproof d sub connector achieves an IP67 protection rating, which means:
Dust Tight: Completely prevents dust ingress.
Water Immersion Protection: Can be immersed in 1 meter of water for 30 minutes without damage.
Implementation: This is achieved via silicone O-rings at the mating interface, waterproof cable glands at the entry point, and ultrasonic welding processes using PBT insulating materials.
Applications
With its characteristics of "compact size, high current, and strong waterproofing," the 2V2 waterproof connector is widely used in:
Industry Typical Applications
Industrial Automation Charging interfaces for AGV/AMR robots, servo motor power lines
Outdoor Equipment LED display power input, outdoor surveillance equipment power supply
New Energy Portable energy storage power output, charging pile control box interfaces
Medical Equipment Operating table power connections, mobile medical cart power supply
Marine Electronics DC power input for marine radar and navigation equipment
4. Solder-Type Installation: Stable & Reliable
"Solder-type" refers to the method where users solder the power wires directly to the connector contacts one by one. Compared to crimp terminals, solder-type offers:
Extremely Low Connection Resistance: Soldering creates a metallic atomic-level fusion, with contact resistance as low as 5mΩ.
Strong Vibration Resistance: Solder joints are less likely to loosen, making them suitable for vibrating environments.
Flexible Wire Gauge Adaptation: Wire gauge can be selected based on current requirements.
