When choosing a high-current battery connector for harsh environments, the following design features are important considerations:
1. Excellent electrical contact of the high-current battery connectors
Reliable electrical contact is a necessary characteristic of any high-current connector. Reed-type contact pieces can ensure optimal performance in the face of high current and mechanical shock.
2. Housing material of the high-current battery connectors
The most commonly used material for high-current battery connectors used in harsh environments is metal, such as corrosion-resistant and waterproof stainless steel. Considering which metal to use to prevent corrosion is especially important in outdoor environments. Connectors made of stainless steel can usually provide the most effective waterproof, dustproof, and corrosion protection.
3. Insulation material of the high-current battery connectors
The insulation material used in high-current battery connectors designed for harsh environments should have a high Comparative Tracking Index, which can measure the electrical breakdown characteristic of insulation material.
4. Sealing grommet of the high-current battery connectors
The sealing grommet used in harsh environment is usually made of fire-resistant and halogen-free compounds. The sealing grommet used in railway applications must comply with the EN45545-2 standard. Fluorinated rubber (less than 150°C), flame-retardant rubber (less than 200°C), and silicone rubber (less than 200°C) usually can be choosed.
5. Compatibility and locking mechanism of the high-current battery connectors
The connector's keyed mating and locking-type accessories can provide better interconnection security in harsh environments. When pairing connectors, different key positions or color coding functions can help ensure error prevention and secure connections.
6. Temperature range of the high-current battery connectors
The working temperature range of the connector should be between at least -40°C and +125°C depending on the different uses. Connectors that can withstand a wider range of operating temperatures, such as -60 ° C to +180 ° C, are better suited to extreme temperatures in energy, downhole drilling and automotive applications.
Long-term reliability and service life are critical to choosing a suitable high-current wire connector. We can help you determine the best solution or develop customized connectors for your application based on different market needs, mechanical parameters, performance characteristics and corresponding industry standards.
