【Product Overview】DC-025BM 8.5mm Extended Thread Panel-Mount DC Power Jack
DC-025BM is specifically designed for devices with thickened panels, featuring a 8.5mm extended thread, all-metal panel-locking DC power jack (female connector)5.5×2.1mm and and 5.5×2.5mm compatible with standard adapter power plugs, fully aligned with the Long-Thread Panel Mount industrial-grade connector design standards.
Addressing the industry pain point where standard jacks have insufficient thread length and inadequate nut grip for thick-walled plastic enclosures, die-cast aluminum chassis, or when protective gaskets are added, the DC-025BM extends the thread length to 8.5mm. The all-metal sleeve, combined with precision threads, a hexagonal metal nut, and washer, ensures secure locking even through thicker panels. The tail wiring terminal adoptsStandard solder lug with hole, making it extremely easy for wire harness hooking and manual flying lead soldering.

1. 8.5mm extended thread, specifically solving the locking challenge of thickened panels
The thread area is significantly extended to 8.5mm, easily penetrating thickened injection-molded shells, aluminum alloy die-cast housings, or chassis panels with waterproof gaskets, ensuring sufficient engagement threads for the hex nut and extremely reliable locking.
2. All-metal sleeve with silver luster, combining high texture and shielding performance
The entire housing is precision electroplated from copper alloy/zinc alloy, presenting a bright and premium metallic texture that is wear-resistant and impact-resistant, while also providing excellent electromagnetic shielding performance, effectively enhancing the quality of end products.
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 compliant with UL94V-0 flame retardant rating, featuring a high heat deflection temperature. During manual soldering iron flying-wire soldering, the housing base remains stable without melting or deforming, maintaining top-level air tightness and insulation resistance at all times.
