Resisting Vibration and Shock: Keeping Connections "Rock-Solid"
Vibration is the primary culprit leading to connector failure. High-performance connectors address this issue in various ways:
Enhanced Mechanical Latches: For example, the ERNI iBridge Ultra series uses Terminal Position Assurance (TPA) technology to provide secondary locking for contacts, preventing loosening due to vibration. Lingke Electric's M12 series uses threaded locking and integrated molding processes to ensure connection integrity.
Innovative Crimping Technology: Igus and HARTING apply Insulation Displacement Connection (IDC) technology to industrial Ethernet, where cutting edges pierce the insulation layer to form an airtight "cold-weld" connection, offering extremely strong anti-aging performance.
Floating Tolerance Design: TE Connectivity's HDC series heavy-duty connectors use a floating design, allowing for up to 1.5 cm positional deviation when AGV carts dock for charging. Automatic correction prevents damage caused by rigid collisions.
Conquering Harsh Environments: Dual Protection for Electrical and Environmental Conditions
To cope with high voltage, high temperature, and corrosion, connectors have undergone significant optimization in materials and structure:
High Voltage and High Current Carrying Capacity: Rosenberger HVR®25 high-voltage connectors are designed for 800V and higher voltage platforms. When using 4mm² copper wires, they can continuously carry 40A of current under an 85°C environment.
High-Performance Contact Materials: Using materials like gold plating effectively prevents oxides formed by fretting wear, maintaining stable contact resistance. The PEM eConnect® system uses copper alloy sleeves plated with silver/tin and features a special knurling design that automatically removes oxide layers during installation, ensuring ultra-low resistance (<10 microohms).
Fully Sealed and Wide Temperature Adaptation: The DEKO 51005 series connectors use UL94V-0 flame-retardant nylon housings, operate over a temperature range of -25°C to 85°C, and have high insulation resistance (≥1000MΩ), making them suitable for all-weather outdoor environments.
Precision and Efficiency: Achieving Big Results in Small Spaces
The trend of miniaturization in equipment requires connectors to maintain high reliability in more compact spaces:
Miniaturized Design: The DECA 51005 series features a 2.0mm ultra-small pitch design, increasing layout density by more than 20%, while cantilever beam-style elastic pins ensure stable connections under vibration.
Solderless Connection Technology: GREENCONN fisheye terminals abandon welding and use mechanical crimping, fundamentally avoiding the risks of cold solder joints and thermal damage, while enhancing structural stability in vibrating environments.
Simplified and Reliable Process: The PEM eConnect® system replaces costly busbar plating and cleaning procedures with a one-step press-fit installation, and its special design can automatically clean the oxide layer during installation.
