1. Commonly Used Imported Connector Brands
• TE Connectivity (Tyco Electronics) – USA
• Molex – USA
• JST (Japan Solderless Terminals) – Japan
• Hirose Electric – Japan
• AMP – USA (a TE Connectivity brand)
• Deutsch – Germany (part of TE, mainly used for rugged environments)
2. Typical Applications in Refrigerator Wiring
Imported CONNECTORS are used in the following areas:
Location / Function Connector Type Requirements
Compressor control Sealed terminal connectors Vibration and heat resistance
Fan motor wiring Small pitch connectors (e.g., JST XH) Compact, secure contacts
Thermostat and sensors Signal connectors Stable transmission, corrosion resistance
Control board (PCB) interfaces Wire-to-board connectors Accurate positioning, high pin count
Door switch and lighting Modular connectors Quick disconnect, reliable mating
3. Key Features of Imported Connectors in Refrigerator Use
• Moisture Resistance: Often include seals or waterproofing structures (e.g., silicone gaskets).
• Heat Resistance: Can endure temperature fluctuations inside the refrigeration and compressor areas.
• Compact Size: Especially for space-limited areas like control panels.
• Reliable Locking Mechanism: Prevents loosening due to long-term vibration or movement.
• Ease of Assembly: Designed for efficient mass production and quick assembly/disassembly.
4. Common Connector Models
Brand Model Series Features
TE Connectivity AMP Mini Universal MATE-N-LOK Modular, secure locking, used in control systems
Molex Micro-Fit 3.0 Compact, high current, often used on PCBs
JST XH / VH / SM Series Small pitch, low current, ideal for sensors and signal lines
Hirose DF11 / DF14 Board-to-wire, highly reliable contact design
5. Advantages of Using Imported Connectors
• High manufacturing precision ensures stable conductivity and long service life
• Comply with international safety standards (e.g., UL, VDE)
• Designed with anti-oxidation and anti-aging materials
• Better tolerance control during high/low temperature cycling
• Some models come with flame-retardant housings (UL94V-0 rated)
6. Challenges / Considerations
• Cost: Generally more expensive than domestic connectors
• Lead Time: May involve longer procurement cycles
• Compatibility: Must ensure connectors are compatible with Chinese wiring specifications or converted via adapters
In some high-end refrigerator models (e.g., smart or inverter models), TE and MOLEX Connectors are used in the main PCB wiring harness to ensure reliable data and power transmission between the inverter board, temperature sensors, and display modules.
