Basic performance classification of Connector

Publish Time: 2024-05-27
As an indispensable component of electronic equipment, the basic performance of Connector determines its stability and reliability in various application scenarios. The basic performance of Connector can be clearly divided into three categories: mechanical performance, electrical performance and environmental performance.

1. Mechanical properties

Mechanical performance is one of the most intuitive properties of the Connector, mainly related to the connector's plugging and unplugging force and mechanical life. The insertion force is divided into insertion force and extraction force. The insertion force is required to be small to improve the convenience of use; while the extraction force must be guaranteed to ensure the reliability of the connection. In relevant standards, the maximum insertion force and minimum separation force are clearly defined, which is also the result of consideration from the perspective of use. In addition, the mechanical life of a Connector is an important indicator for evaluating its durability, which is usually measured by the number of plugging and unplugging times.

2. Electrical performance

Electrical performance is the core of Connector performance, mainly including contact resistance, insulation resistance and electrical strength. Contact resistance is the resistance generated when current passes between connector contacts. A high-quality Connector should have low and stable contact resistance. Insulation resistance is an indicator of the insulation performance between Connector contacts and between contacts and housing. Its magnitude generally ranges from hundreds of megohms to thousands of megohms. Electrical strength represents the ability of the Connector contacts to withstand the rated test voltage or between the contacts and the housing.

3. Environmental performance

Environmental performance is the Connector's ability to adapt to various environmental conditions, mainly including temperature resistance, moisture resistance, salt spray resistance, vibration and impact resistance, etc. These properties determine the stability and reliability of the Connector under different environmental conditions. For example, the temperature resistance range of a connector is generally -65°C to 200°C (except for a few high-temperature special connectors), and the moisture resistance and salt spray resistance are evaluated through specific test conditions.

To sum up, the basic performance of Connector can be clearly divided into three categories: mechanical performance, electrical performance and environmental performance. These performances are interrelated and influence each other, and jointly determine the overall performance and usage effect of the Connector.
