Connector high temperature testing usually has three basic thermal environments to be considered: 1 Life under temperature conditions 2 Cycles under thermal conditions 3 Vibration under thermal conditions Thermal cycle testing The so-called thermal cycle test refers to continuous time The temperature is constantly changing between two extreme points. If the temperature cycle test under humid conditions removes the factor of humidity during the test, their test results are the same. Usually the test in this environment is used to evaluate the factors mentioned above and the deterioration of quality due to wear under the action of temperature and the non-fitting condition of the connector system due to heat-related expansion. If it is evaluated that there are potential corrosion factors, the duration of the durability test is usually extended, because in this case, the humidity factor that can accelerate the oxidation process of the electrical connector does not work. Just like the cycle under temperature/humidity conditions described above, special attention must be paid to establishing the number of consecutive measurements. And through the expected operating conditions of the electrical connector to establish its temperature limit. The same property that affects its life under temperature conditions is generally very similar in terms of its test methods. So far, there has not been a set of fixed procedures for this type of test, although certain temperature/humidity tests under the same conditions have been adopted. program of. At present, the standard furnace has been adopted in other occasions except for the standard furnace that is unexpectedly low temperature obtained by liquid nitrogen and cannot be applied under the control of a microprocessor. Thermal vibration test
If the thermal cycle test is not carried out in a continuous time, the thermal vibration test has the same effect as the thermal cycle test. In the two temperature limits, the faster the transition time, the more the thermal shock test will be affected. The thermal shock is mainly determined by simulating the limit conditions of its storage, transportation and application to determine the damage to the electrical connector during the continuous conversion within the limit temperature. endurance.
