【Key B2B Selling Points and Process Advantages】
1. Standard PCB pin design for fast soldering and wave soldering
The pins are made of high-quality copper alloy with a finely tin/silver-plated surface, offering excellent solderability and oxidation resistance. They are easy to tin, free from cold solder joints, and perfectly compatible with SMT pre-treatment and automated wave soldering lines, significantly improving factory assembly efficiency.
2. High-elasticity phosphor bronze contacts for low contact resistance and long lifespan
The internal contact springs are made of high-elasticity phosphor bronze, combined with a well-designed clamping force structure. After rigorous mechanical insertion/withdrawal testing of over 5,000 cycles, the spring force remains durable without degradation, effectively preventing arcing and poor contact.
3. High-temperature-resistant flame-retardant housing for insulation safety
The main insulating housing is made of high-strength, high-temperature-resistant engineering plastics (such as PBT/PA66), offering excellent electrical insulation, heat resistance, and mechanical strength. It resists deformation and melting under high-temperature soldering or heavy-load operating conditions.
4. Compact horizontal structure to save PCB space
Classic right-angle horizontal layout, fits PCB board openings, occupies minimal board area, and allows smooth side insertion, making it especially suitable for thin-profile devices and electronic products with compact enclosure structures.
---【Main Application Industries and Scenarios】
The DC-005 horizontal PCB-mount DC power socket, with its excellent versatility and cost-effectiveness, is widely used in the following fields:
- Security and Communication Equipment: Power input interfaces for network cameras (IP Camera), routers, switches, access control and attendance machines.
- Small Appliances and Smart Hardware: Charging bases for robot vacuums, smart speakers, air purifiers, and LED desk lamp controllers.
- Medical and Test Instruments: Portable medical monitoring devices, electronic test instruments, and digital teaching equipment.
