II. Product Features
Pure Copper High Current Design, Anti-Spark & Safe Stable
DC-005 power jack adopts high-purity electrolytic copper integrally stamped for core terminals, with excellent electrical and thermal conductivity to carry high current load far beyond ordinary sockets, meeting power supply demands of high-power equipment.
Innovative anti-spark contact structure effectively suppresses arcing during plug-in and unplugging, fundamentally avoiding contact oxidation, equipment short circuit and other hidden dangers, greatly improving safety and service life, suitable for high-frequency high-current scenarios such as industrial welding machines and high-power energy storage devices.
Reinforced Mechanical Structure, Firm Installation & Connection
The socket uses thickened metal reeds and reinforced housing with built-in bidirectional elastic clamping, providing tighter fitting with DC plugs, less prone to loosening or falling off, and improving vibration and impact resistance by more than 50%.
Supports through-hole mounting with industry-standard pin spacing, directly insertable into PCB preset holes. Strong bonding force after soldering, adapting to complex working conditions with frequent movement and vibration such as industrial equipment and vehicle power supplies to ensure continuous stable power supply.
High-Temperature Flame-Retardant Material, Excellent Environmental Adaptability
Housing uses high-temperature resistant flame-retardant engineering plastic with outstanding fire resistance, capable of withstanding 260℃ wave soldering without deformation, softening or cracking, suitable for mass automated production lines.
Operating temperature range: -40℃~120℃, resistant to thermal cycling shocks.
Excellent moisture and corrosion resistance, stable in 10%–95% humidity and mildly dusty or oily environments, meeting harsh requirements in outdoor, industrial and other fields.
Anti-Reverse & Anti-Misinsertion Design, Convenient & Efficient Operation
Dual design of polarized port and anti-misinsertion slot allows only correct plug orientation, effectively preventing circuit burnout and equipment damage caused by reverse insertion.
Rounded port edges avoid scratching wires and enable quick direction recognition, improving assembly efficiency.
Built-in dustproof structure supports optional dust cover to block dust and debris when idle, extending terminal service life.

V. FAQ
Q1: How to quickly select the right DC-005 pure copper high-current model?
A1: Confirm based on three core dimensions:
① Rated current and 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 demands.
Our technicians will provide accurate selection suggestions within 1 hour.
Q2: How to solve unstable power or sparking 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 sparking continues, check whether the device current exceeds the socket rating or replace with a new DC-005 high-current socket.
Q3: What key parameters are required for customizing DC-005?
A3: Provide the following core information:
① Basic specifications (rated voltage/current, port inner diameter, socket height);
② Structural requirements (dust cover, anti-misinsertion position, mounting method);
③ Performance requirements (temperature resistance, plugging life, anti-spark level);
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
