【Product Overview】DC-022B Metal-Trimmed Threaded Nut-Fixed Panel-Mount DC Power Socket
DC-022B is a high-quality metal-trimmed threaded panel-lock DC power socket (female connector)5.5×2.1mm and and 5.5×2.5mm designed for standard adapter power plugs, fully aligned with international general-purpose Panel Mount high-quality connector design standards.
Unlike ordinary all-plastic sockets, the DC-022B front features abright silver metal trim ring (Metal Ring Trim)design, which not only imparts a premium feel and industrial aesthetics to end devices but also effectively prevents front-edge plastic wear and cracking caused by angled plug insertion and friction during frequent plugging and unplugging. The body is equipped withFine thread and hexagonal metal nut, simply by making a circular opening on the panel for a secure lock. The tail terminal usesStandard solder lug with hole, making it extremely easy for wire harness hooking and manual flying lead soldering.

1. Bright silver metal-wrapped front ring, combining aesthetic texture with wear resistance and durability
The front metal ring greatly enhances the premium feel of the exposed panel, and the high hardness of the metal material completely avoids lateral scratches and mechanical impact damage during the insertion and removal of the power male plug, significantly extending the appearance and physical lifespan of the socket.
2. Circular threaded locking, compact and secure against loosening
The housing is equipped with precision threads and a hexagonal metal nut, allowing for quick installation with just a single circular hole on the panel. The locking force is evenly distributed, and with the included washer, it can withstand high-intensity vibration, preventing interface loosening during use.
3. Perforated solder lug, providing strong tin adhesion and pull resistance
The tail three-pin terminal block features standard wire-through holes; wires are threaded through in a staggered pattern before soldering, resulting in full solder fill and low contact resistance. Combined with heat-shrink tubing insulation, it effectively withstands the tensile stress of internal wire harnesses within the chassis, eliminating cold solder joints.
4. High-insulation, high-temperature-resistant engineering plastic base
The interior is injection-molded from high heat-resistant engineering plastic that complies with the UL94V-0 flame retardant rating. During manual soldering iron fly-wire welding, the housing base remains stable, without melting or deforming, maintaining top-level air tightness and insulation resistance at all times.
