Reliability testing of coaxial terminals is essential to ensure their proper functioning under various conditions over an extended period.

　　One common reliability test is the environmental test. This includes temperature cycling tests, where the coaxial terminal is repeatedly exposed to high and low temperatures within a specified range. For example, the terminal may be cycled between - 40°C and 85°C for a certain number of cycles. This test helps to identify any potential issues caused by thermal expansion and contraction, such as cracks in the conductors or loosening of connections. Humidity testing is also important, especially for coaxial terminals used in outdoor or high - humidity environments. The terminal is placed in a chamber with a controlled high - humidity level (e.g., 95% relative humidity) for a specific duration to check for corrosion or moisture - induced performance degradation.

　　Mechanical reliability tests involve subjecting the coaxial terminal to mechanical stresses. Vibration testing is carried out by placing the terminal on a vibration table and exposing it to different vibration frequencies and amplitudes. This simulates real - world conditions where the terminal may be exposed to vibrations, such as in automotive or aerospace applications. Mechanical shock testing, on the other hand, exposes the terminal to sudden high - force impacts to test its ability to withstand accidental drops or impacts.

　　Electrical reliability tests focus on the long - term performance of the coaxial terminal under electrical loads. High - voltage endurance testing is performed by applying a high voltage (above the normal operating voltage) to the terminal for an extended period to check for insulation breakdown. In addition, signal integrity tests are conducted over a long time to monitor parameters like attenuation and reflection coefficient to ensure they remain within acceptable limits.
