Product Introduction

【Product Overview】DC-019 Long Strip with Ears Screw-Fixed Panel DC Power Socket

DC-019 is a panel-mount DC power socket (female connector) specifically designed for thin and compact enclosures, featuring a long strip rectangular with ears screw-fixed design5.5×2.1mm and and 5.5×2.5mm Standard adapter power plugs, fully aligned with the Flange Mount industrial-grade panel connector design standards of international manufacturers such as TE Connectivity and Amphenol.

DC-019 uniquely adopts along strip flat rectangular flange ear (Rectangular Flange)structure. During installation, it is securely fastened to the device enclosure via screws on both sides, providing exceptionalTensile resistance, impact resistance, and vibration resistance, it can also greatly save the vertical height space of the panel. The front deeply recessed cavity can effectively protect the exposed part of the plug, and the tail terminals adoptStandard solder lug with hole, which is extremely convenient for wire harness hooking and manual flying wire soldering.

[Expert-Level B-Side Selling Points and B2B Procurement Decision Factors]

1. Long rectangular flange ears, specially designed for thin and height-restricted panels

The horizontal elongated flange design effectively disperses the panel locking stress, achieving extremely high mechanical fixing strength while avoiding the limitation of excessive longitudinal dimensions on narrow chassis layouts.

2. Recessed safety cavity, effectively protecting against lateral impact

The front of the socket features a deeply recessed protective rim. When the power adapter male plug is inserted, the connection becomes more stable, effectively resisting accidental lateral bumps and severe pulling, preventing socket cracking or loosening under stress.

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-impact, flame-retardant engineering plastic base

Molded from high-heat-resistant engineering plastic that meets UL94V-0 flame retardant rating, with a high heat deflection temperature. During manual soldering iron wire-connection processes, the housing base does not shift, melt, or deform, maintaining top-level air tightness and insulation resistance at all times.
