II. Product Features
3-Pin Integrated Design, Strong Function Compatibility
Adopting a 3-pin integrated structure, it supports both audio signal transmission and DC power supply in one component, eliminating the need for separate interfaces on the PCB and greatly saving board space.
Ideal for compact electronic devices requiring simultaneous audio and power input, such as portable speakers, security surveillance equipment and medical detectors.
Pin spacing complies with industry common standards, directly matching mainstream circuit designs and reducing development and adaptation difficulty.
High-Stability Contact Structure, Excellent Connection Reliability
Socket terminals are made of high-purity electrolytic copper with nickel-gold plating, ensuring contact resistance ≤30mΩ to effectively reduce signal loss and voltage drop, avoiding equipment noise, power failure and other issues caused by poor contact.
Built-in elastic clamping reeds provide uniform and stable insertion force. Plugging life reaches more than 10,000 cycles, maintaining firm connection even in high-vibration environments, suitable for harsh scenarios such as automotive and industrial equipment.
Anti-Misinsertion & Polarized Design, Safe and Convenient Operation
Innovative anti-misinsertion slots and polarized pin design accurately identify plug direction, effectively preventing short circuits and equipment burnout caused by reversed insertion.
The socket port is equipped with a dustproof silicone plug to block dust and oil when idle, protecting terminals from corrosion and oxidation and extending service life.
Smooth plugging feel allows insertion and removal without additional tools, improving user experience.
Wide Temperature Resistance, Strong Environmental Adaptability
Housing uses high-temperature resistant flame-retardant PC engineering plastic, capable of withstanding 260℃ reflow soldering without deformation or softening.
The product operates stably in a wide temperature range of -40℃ to 120℃ and withstands high-low temperature cycling shocks.
It features excellent moisture and corrosion resistance, performing reliably in 10%-95% relative humidity and mildly dusty or humid environments, adapting to complex working conditions in automotive, outdoor security, medical and other fields.
III. Product Advantages
Digital Manufacturing Control, Excellent Quality Consistency
Introducing an MES digital production management system, we monitor key process parameters such as stamping pressure, injection mold temperature and terminal plating thickness in real time, with deviations controlled within ±0.01mm and ±1μm.
Equipped with a multi-camera visual inspection system, it accurately identifies 15 types of defects including skewed pins, plating peeling and housing deformation.
Product defect rate is controlled below 0.08%, ensuring stable and consistent quality in mass delivery.
Standardized Compatible Design, Lower Adaptation Cost
Package dimensions and pin definitions comply with IEC international standards and are compatible with mainstream PCB design software libraries such as Altium and Cadence, requiring no board redesign.
Directly compatible with mainstream 3-pin audio DC plugs on the market, reducing mold modification costs and accelerating project progress.
Flexible Production Response, Efficient Customization
A modular production system improves response speed by 45% compared to the industry average for customized requirements such as special pin length, socket height and anti-misinsertion structure.
Regular models are in stock and can be shipped within 72 hours.
For customized products, we provide one-stop service from structural design and sample prototyping to mass delivery based on independent mold development capability, with a minimum sample lead time of only 3 working days.
Full-Cycle Service Support, Worry-Free Cooperation
A professional technical team provides early selection guidance, mid-term soldering process optimization and later troubleshooting, with an after-sales response time of no more than 24 hours.
Products support forward raw material traceability and reverse defect tracing, with full-process production data available in real time, fully meeting strict compliance requirements in automotive, medical, industrial automation and other industries.

V. FAQ
Q1: How to quickly select the right model of 3-pin audio & DC power socket?
A1: Confirm based on three core dimensions:
① Pin length, socket height and anti-misinsertion type;
② PCB pad size, mounting type (SMT/through-hole) and soldering process;
③ Operating environment (temperature, humidity, vibration) and signal type.
Our technicians will provide accurate selection suggestions within 1 hour.
Q2: How to solve poor contact or noise during use?
A2: First, power off and check whether 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 the same specification socket.
Q3: What key parameters are required for customizing this combined socket?
A3: Please provide:
① Basic specifications (pin length, socket height, port inner diameter);
② Structural requirements (anti-misinsertion position, dust plug, mounting type);
③ Performance requirements (temperature resistance, plugging life, vibration resistance);
④ Installation requirements (PCB pad size, soldering process);
⑤ Volume demand and delivery schedule.
