The performance of battery pack wire connectors depends significantly on the materials used in their construction. Two key materials commonly found in high-current connectors are thermoplastics and copper alloys. Thermoplastics,are often used for the connector body due to their flame-retardant properties and ability to withstand high temperatures. They ensure durability and safety in demanding industrial environments. For the contact components, copper alloy is a preferred choice due to its excellent conductivity and resistance to corrosion. For example, the 2+6 70A battery pack wire connectors use these materials, delivering a rated current of 20-70A for power and 3A for signals, with a rated voltage of 500V DC. These connectors are also RoHS compliant, guaranteeing environmentally friendly materials that meet strict industry standards. When selecting high-current connectors, businesses should always opt for those made with high-quality, compliant materials to ensure long-lasting performance and safety.
