[Product Overview] DC-025M All-Metal Threaded Panel-Mount DC Power Socket

DC-025M is designed with a standard metal threaded sleeve as an all-metal panel-locking DC power socket (female connector)5.5×2.1mm and and 5.5×2.5mm compatible with standard adapter power male plugs, fully aligned with Metal Panel Mount industrial-grade connector design standards.

The DC-025M featuresan all-metal precision-machined/plated outer sleeve with precision threads, accompanied by a hex metal nut and washer. Simply reserve a standard circular opening on the panel to achieve high-strength fastening and locking. The all-metal outer sleeve not only provides excellent mechanical strength and scratch/wear resistance but also offers good electromagnetic shielding. The tail terminal adoptsStandard solder lug with hole, facilitating wire threading, hooking, and manual soldering iron welding.

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

1. Standard metal threaded bushing, securely locked to prevent loosening

Featuring precision fine-pitch metal threads paired with a hex nut and lock washer, the tightening force is evenly distributed, effectively withstanding lateral pull forces and mechanical vibration during frequent plug insertion and removal, ensuring the socket remains flush against the panel without loosening.

2. All-metal shell and metallic finish, combining premium aesthetics with electromagnetic shielding

The entire housing is crafted from high-quality metal with surface electroplating treatment, offering a smooth, premium appearance that is wear-resistant and impact-resistant, while also providing excellent electromagnetic shielding to enhance the overall quality of the end product.

3. Perforated solder lug, providing strong tin adhesion and pull resistance

The tail terminals are all equipped with standard wire-through holes. After threading the wires through and interweaving them, soldering is performed, resulting in full tin coverage and low contact resistance. Combined with insulating sleeving, this effectively withstands the tensile stress of internal wiring 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 meets UL94V-0 flame retardancy rating, with a high heat deflection temperature. During manual soldering iron welding, the housing base remains stable without melting or deforming, and insulation resistance and conductivity performance consistently maintain top-tier levels.
