Environmental performance of automotive connectors

Automotive connector environmental performance mainly includes temperature resistance, moisture resistance and impact resistance of the three major properties.1. Automotive connector environmental performance of temperature resistance: because the automotive connector used in automotive circuits, it is easy to generate heat in the contact point, the temperature rises, which requires automotive connectors with high temperature performance, the current connector higher operating temperature is 200 ℃. At the same time, in some special circumstances, the automotive connector will be used in a low-temperature environment, so the low-temperature resistance of the automotive connector should also be good, at present, the automotive connector's lower operating temperature is -65 ° C. 2. automotive connector environmental performance of the humidity resistance: why pay attention to the automotive connector's resistance to moisture? Shanghai automotive connector manufacturers said that the metal parts of the automotive connector is easy to corrode in humid environments, and in some cases, the automotive connector may need to work in a humid environment, so the moisture resistance has also become an important performance in the environmental performance of the automotive connector. Generally speaking, qualified automotive connectors need to be in the relative humidity of 90% ~ 95%, temperature +40 ± 20 ℃, at least 96 hours of continuous normal operation for qualified products.3. Automotive connector environmental performance of impact resistance: impact resistance is an important performance indicator of the environmental performance of automotive connectors, on behalf of the connector's robustness. In the test, to detect the peak acceleration of the connector, electrical continuity interruption time. The safety performance of automotive connectors is the most important of the entire product, so the quality must not be relaxed, each indicator needs to be tested.
