Connectors, that is, connectors or plugs and sockets, play a vital role in electronic and electrical systems. Their basic performance can be evaluated from the following aspects:

Electrical performance:

Rated current and voltage: refers to the maximum current and voltage that the connector can safely handle.

Contact resistance: the resistance between contact points, which affects the efficiency of energy transmission and generates heat.

Insulation resistance: the resistance between connecting parts to prevent current leakage.

Dielectric strength: the maximum voltage that can be sustained will not be broken down.

Mechanical properties:

Insertion force: the force required to insert and pull out the plug.

Durability: The number of times the connector can be plugged and unplugged will not significantly reduce its performance.

Stability of mechanical properties: whether the physical structure of the connector is stable and can withstand mechanical stress.

Environmental adaptability:

Temperature range: the temperature range where the connector can work normally.

Humidity, corrosion, vibration and impact: able to withstand environmental conditions such as high humidity, salt spray corrosion, vibration and impact.

Compatibility and standardization:

Physical size and shape: ensure compatibility with the corresponding socket or equipment.

Standardization: conforming to international or national standards and ensuring compatibility with different equipment.

Materials and manufacturing quality:

Conductive material: copper or copper alloy is generally used, and sometimes it is plated with gold or silver to improve the conductivity and corrosion resistance.

Insulation material: such as plastic or rubber, used to prevent electrical short circuit and electric shock of users.

Security features:

Protection grade: such as IP grade, indicating dustproof and waterproof ability.

Fire and flame retardant performance: the ability to prevent fire under overload or fault conditions.

Understanding and evaluating these performance indicators is very important for selecting the appropriate connector, especially in terms of safety and reliability. Different application scenarios will have different emphasis on the performance requirements of connectors.
