How to Scientifically Select Electrical Connectors? — A Professional Selection Guide

Electrical connectors come in a wide range of types and specifications, and choosing the right product is crucial to ensuring the stable operation of equipment. When selecting a connector, in addition to matching the space occupied and size constraints of the equipment, the core lies in comprehensively evaluating three key dimensions: electrical parameters, mechanical parameters, and natural environment parameters.

1. Accurately Match Electrical Parameters to Ensure Circuit Safety

First, clarify the core requirements of the equipment for electrical performance, focusing on the following aspects:

• Voltage/Current: Must match the rated value of the connector to avoid damage caused by overload;

• Contact Resistance: Select models with low contact resistance to reduce signal loss;

• Insulation Resistance/Voltage Withstand: Ensure stable insulation performance under rated working conditions to prevent leakage risks.

2. Focus on Mechanical Parameters to Adapt to Equipment Working Conditions

Combined with the equipment's installation, usage, and maintenance scenarios, focus on considering 5 key indicators:

1. Vibration and Shock Resistance: According to the vibration/shock level of the equipment's actual operating environment (such as industrial machinery, transportation vehicles), select connectors with corresponding anti-interference performance;

2. Reliable Locking Method: Optional methods include bayonet, thread, snap-lock, and push-pull. Among them, threaded connection has the best anti-vibration performance; for high-vibration scenarios, additional fuses can be installed for reinforcement to prevent connection loosening;

3. Anti-Misplug Design: Adopt a multi-group positioning key structure to effectively prevent misplugging of adjacent similar connectors and reduce equipment failure risks;

4. Flexible Installation Adaptation: Choose the front-mounted or rear-mounted socket installation method according to the internal structure of the equipment to improve installation convenience;

5. Maintainability: Combined with subsequent maintenance needs, select models that are easy to disassemble and have suitable termination methods (for detailed selection materials, please refer to: www.tsssk.com).

3. Adapt to the Natural Environment to Extend Service Life

Select connectors in a targeted manner based on the environmental characteristics of the connector's usage scenario:

1. Ambient Temperature: Match the high and low temperature range of the equipment's working environment according to the temperature resistance limit of metals and insulating materials;

2. Moisture and Water Resistance: For outdoor or humid environments (such as bathrooms, outdoor equipment), high-sealing connectors must be selected to prevent water seepage and pollution from affecting performance;

3. Corrosion Resistance: For scenarios such as salt spray (marine environment) and mold (hot and humid environment), select connectors with corresponding corrosion-resistant metals, plastics, and coatings.
