II. Product Features
Compact Structure, Excellent Space Adaptability
DC-044 power socket adopts a standard compact package with industry-standard dimensions, occupying minimal PCB space and perfectly meeting the layout requirements of miniaturized and ultra-thin electronic devices.
The pin layout is scientific and reasonable, directly compatible with mainstream circuit designs and various soldering processes including manual soldering, wave soldering and reflow soldering, greatly reducing integration difficulty and improving PCB space utilization.
High-Conductivity Durable Terminals, Stable & Safe Power Supply
Internal terminals are made of high-purity electrolytic copper with nickel-tin double-layer plating, delivering excellent conductivity and corrosion resistance with contact resistance ≤30mΩ, effectively reducing voltage drop and overheating risks during power supply.
Built-in elastic clamping reeds provide uniform force and outstanding resilience, maintaining tight contact with DC plugs to avoid power failure or restart caused by poor connection. Plugging life reaches more than 8000 cycles, far exceeding industry standards.
Anti-Reverse & Anti-Misinsertion Design, Easy & Safe Operation
Innovative polarized port structure allows only correct plug orientation, structurally eliminating short circuits and equipment burnout due to reverse insertion.
The port features rounded edges to prevent wire scratches and enable quick direction recognition, improving assembly efficiency.
Dust covers are available for customization to block dust and oil when idle, extending terminal service life.
Wide Temperature & Weather Resistance, Strong Environmental Adaptability
Housing uses high-temperature resistant flame-retardant PC engineering plastic, capable of withstanding 260℃ high-temperature soldering without deformation, softening or cracking, suitable for mass automated production.
The product operates stably in a wide temperature range of -40℃ to 120℃ and withstands thermal cycling shocks.
It features excellent moisture and corrosion resistance, performing reliably in 10%–95% humidity and mildly dusty or oily environments, meeting harsh requirements in automotive, outdoor security and industrial control applications.

V. FAQ
Q1: How to quickly select the right DC-044 model?
A1: Confirm based on three core dimensions:
① Mounting type (through-hole/SMT), port specification (5.5×2.1 / 5.5×2.5, etc.);
② PCB thickness, mounting hole size and soldering process requirements;
③ Operating environment (temperature, humidity, vibration frequency) and power voltage/current demands.
Our technicians will provide accurate selection suggestions within 1 hour.
Q2: How to solve unstable power supply or poor contact during use?
A2: First disconnect power and check if the plug is fully inserted without looseness. If contacts are contaminated, gently clean internal terminals and plug surfaces with anhydrous alcohol and a micro swab, then retest after full drying. If the problem persists, check for terminal oxidation or reed deformation and replace with a new DC-044 socket.
Q3: What key parameters are required for customizing DC-044?
A3: Provide the following core information:
① Basic specifications (socket height, pin length, port inner diameter);
② Structural requirements (dust cover, anti-misinsertion position, mounting method);
③ Performance requirements (temperature resistance, plugging life, rated voltage/current);
④ Installation requirements (PCB thickness, mounting hole size, soldering type);
⑤ Order quantity and delivery schedule.
We will provide a detailed customized plan and quotation accordingly
