High-Performance Connector Assembly for Motor Protectors (Model 3056045)

Craftsmanship-Driven Manufacturing

As a leading connector assembly manufacturer in China, HAIPART combines precision engineering with uncompromising quality control. Every assembly undergoes 12 critical inspection stages:

• Raw material screening

• Conductivity validation

• Insulation withstand voltage testing

• Temperature rise cycling

• 10,000+ mechanical life simulations

• Digital verification of bolt torque/insulation thickness

“We digitally control even the strength of a single fixing bolt and wall thickness of insulating components to ensure customers’ peace of mind during installation and reliable operation.”

Technical Highlights

1. Conductive System

• Material: CuCr25 silver-based composite contacts

• Arc Erosion: <0.05mm³/stroke (validated test data)

• Innovation: Trapezoidal pin design with ±10% contact pressure self-adjustment

• Benefit: Compensates for thermal expansion/contraction

2. Insulation System

• Material: Nano-modified PA66 housing (CTI ≥ 600V)

• Certification: Passed glow-wire test (750°C/30s)

• Sealing: Integrated silicone rubber seals

• Protection: IP65 rating (supports live plugging/unplugging)

3. Connection Mechanism

• Precision: Dual guide posts + anti-misinsertion coding slots

• Tolerance: ±0.5mm insertion alignment

• Security: Torque self-locking mechanism (20N·m ±10%)

• Benefit: Zero loosening under vibration
