Why should the terminal be tested after the terminal wire harness is processed?
The terminal inspection is to evaluate the characteristics of the terminal and whether the product can meet the applicable regulations. In addition, the terminal inspection is also a continuation of the design product and design stage. Radio frequency connectors with different functions focus on different inspections. In summary, most of the terminal test codes mentioned above include three new items: electrical equipment function testing, natural environment function testing, and physical performance testing.
Electrical equipment function tests include AC withstand voltage test, ground resistance, loop resistance, electrical continuity between enclosures, and magnetic permeability. This is mainly to detect whether the radio frequency connector can achieve relative regulations under the rated working standard voltage and the main performance of some characteristics of the resistor current. And then certify the role of the RF connector.
The natural environment characteristic experiment includes corrosion resistance, cold and humid experiment, temperature service life, liquid prepreg, ultra-low temperature and low pressure, active oxygen exposure, fire safety and other tests are all new items belonging to the natural environment characteristic experiment. Certain pertinence.
Physical performance experiments include impact, vibration, and service life of mechanical equipment, etc.
