II. Product Features
Long-Pin Reinforced Structure for Outstanding Installation Stability
DC-044B features an integrated extended positioning pin design, suitable for thick PCBs and sheet metal panels. It can penetrate the mounting substrate and be locked with nuts, improving vibration and impact resistance by more than 60% compared with standard short-pin sockets.
It effectively prevents loosening or detachment caused by frequent equipment movement and vibration, making it ideal for vehicle-mounted devices, industrial handheld terminals and other high-frequency mobile scenarios.
The main body dimensions comply with industry common standards, compatible with mainstream DC power plug specifications without additional structural adjustments.
High-Conductivity Durable Terminals for Safe & Stable Power Supply
Internal terminals are made of high-purity electrolytic copper with nickel-tin double-layer plating, ensuring contact resistance ≤30mΩ to greatly reduce voltage drop and heating during power supply, guaranteeing stable operation under rated current.
Built-in elastic clamping reeds provide uniform force and excellent resilience, maintaining tight contact with power plugs to avoid power failure or restart due to poor connection. Plugging life reaches more than 8000 cycles, far exceeding industry standards.
Anti-Reverse & Anti-Misinsertion Design for Safe & Convenient Use
Innovative polarized port design allows only correct plug orientation, structurally eliminating short circuits and equipment burnout caused by reverse insertion.
The socket port is finished with rounded edges to prevent scratching plug wires and enable quick manual 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 for Harsh Working Conditions
Housing uses high-temperature resistant flame-retardant PC engineering plastic, capable of withstanding 260℃ wave soldering and reflow soldering without deformation, softening or cracking, suitable for mass automated production lines.
The product operates stably in a wide temperature range of -40℃ to 120℃ and resists thermal cycling shocks.
It features excellent moisture and corrosion resistance, performing reliably in 10%–95% relative humidity and mildly dusty or oily environments, meeting complex application requirements in automotive, outdoor security, industrial control and other fields.

V. FAQ
Q1: How to quickly select the right DC-044B long-pin power socket model?
A1: Confirm based on three core dimensions:
① Positioning pin length and port specification (5.5×2.1 / 5.5×2.5, etc.);
② PCB/panel thickness, mounting hole size and soldering process requirements;
③ Operating environment (temperature, humidity, vibration frequency) and power voltage/current requirements.
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 and the fixing nut is tight. 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-044B long-pin socket.
Q3: What key parameters are required for customizing DC-044B?
A3: Provide the following core information:
① Basic specifications (positioning pin length, socket height, port inner diameter);
② Structural requirements (dust cover, anti-misinsertion position, fixing method);
③ Performance requirements (temperature resistance, plugging life, rated voltage/current);
④ Installation requirements (substrate thickness, mounting hole size, soldering type);
⑤ Order quantity and delivery schedule.
We will provide a detailed customized plan and quotation accordingly.
