Connectors have three basic performance types: mechanical performance, electrical performance, and environmental performance. The arrival of the 5G era also requires connectors to be able to undertake the functions of converting electrical signals, optical signals, and shielding. Connectors are essential electronic components, and the emphasis on connector performance varies in different fields.
Mechanical performance: refers to the ability of a connector to operate normally under various mechanical external impacts. Insertion and extraction force and mechanical life are important mechanical properties of connectors. Insertion and extraction force refer to insertion force and extraction force, while mechanical life refers to the durability index of machinery, based on whether the connector can complete the connection function normally after the specified insertion and extraction cycle.
The insertion and extraction force and mechanical life of connectors are related to the structure of the contact parts, the quality of the coating on the contact parts, and the accuracy of the arrangement dimensions of the contact parts.
Electrical performance: refers to the ability of a connector to maintain normal connection function under different current and voltage conditions, mainly including contact resistance, insulation resistance, electrical resistance, and electromagnetic interference shielding effect. Other electrical indicators such as RF coaxial connectors include characteristic impedance, insertion loss, reflection coefficient, voltage standing wave ratio, etc; High speed signal connectors have also encountered new electrical indicators such as crosstalk, transmission delay, and time delay.
Environmental performance: refers to the ability of a connector to maintain normal operation in various environments. Common environmental performance includes temperature resistance, humidity resistance, salt spray resistance, vibration, impact resistance, etc. Other environmental performance also includes sealing, liquid immersion, low pressure, etc.
