Precision machined copper slotted double-ear connection piece for intelligent hardware accessories ​

Connector (Electrical Connector / Signal Connector)

1. Core User Requirements

• Stable power transmission / signal transmission without interruption
• Waterproof and dustproof, no water ingress in outdoor / humid environments
• Easy plugging and unplugging, accurate positioning, no reverse installation
• No loosening, falling off or arcing in vibrating environments

2. Key Points for Customization

(1) Electrical Performance

• Contact resistance: the smaller the better (generally ≤ 20mΩ)
• Rated current / voltage: derating usage for higher safety
• Pin / socket retention force: prevent disconnection
• Insertion and extraction force: too loose leads to poor contact, too tight damages terminals

(2) Sealing and Protection Level

• IP54: splash-proof
• IP65: jet-proof
• IP67: short-time immersion
• IP68: continuous immersion
• Key factors: sealing ring compression rate, structural waterproofing, cable end sealing

(3) Structural Reliability

• Fool-proof / mis-insertion prevention: positioning keys, asymmetric structure, anti-rotation plane
• Anti-loosening: thread, buckle, spring plate, nut locking
• Housing strength: impact resistance, bending resistance, torsion resistance

(4) Materials and Environmental Compliance

• Conductive components: brass, phosphor bronze, beryllium copper (compliant with EU standards)
• Plating: gold plating, silver plating, nickel plating
• Environmental standards: RoHS, REACH
• Automotive grade: IATF16949, CQC, UL

3. Typical Applications

• Automotive: body, engine, lamp, sensor, battery pack
• Industrial control: servo motor, encoder, sensor, PLC
• Outdoor: street lamp, monitoring, charging pile, base station
• Home appliances: air conditioner, washing machine, coffee machine, robotic vacuum cleaner
• Medical: monitor, ultrasound, surgical equipment

4. Professional Material Selection

• Conductive contacts: nickel-plated brass, phosphor bronze, beryllium copper, gold / silver plating
• Housing:
  • Low cost: zinc alloy
  • Lightweight: aluminum alloy
  • High strength & corrosion resistance: 303/304/316 stainless steel
• High frequency / high reliability: red copper, silver alloy contacts
• High temperature / strong corrosion resistance: PPS + glass fiber, PEEK
