【B-end Core Selling Points and Product Advantages】

1. Threaded nut anti-loosening design for stable installation

The DC-022 adopts a high-precision circular threaded hole design, paired with a dedicated metal nut. After opening a hole in the device housing, it can be quickly inserted and locked, offering excellent tensile and vibration resistance, making it especially suitable for industrial equipment and outdoor terminals with high requirements for housing assembly tightness.

2. High-quality brass nickel-plated contacts, low contact resistance and high durability

The internal contact components of the socket use high-elasticity brass/bronze with nickel/silver plating, providing strong oxidation and corrosion resistance and excellent electrical conductivity. After more than 5,000 mechanical insertion and withdrawal tests, the contacts remain tight, with no sparks or loose connections, significantly extending the service life of the entire device.

3. Standard 3-pin solder terminal, more flexible circuit switching

The standard 3-Pin terminal design provides positive and negative power input, as well as automatic cutoff/switching to internal battery power. The pins are easy to solder and provide strong solder joints, effectively improving soldering efficiency and assembly pass rates on factory production lines.

4. Optional waterproof and dustproof cover to enhance protection rating

An optional dedicated rubber dust cap/waterproof cover can be configured based on customer requirements, providing effective dust and water protection when the DC plug is not inserted, ensuring electrical safety in outdoor and harsh industrial environments.
