Waterproof connector common environmental performance indicators, including temperature, humidity, salt spray, vibration and shock resistance.
1. temperature. Currently connector maximum operating temperature of 200oC (except special connector outside temperature), the minimum temperature is -65oC. Since the connector is working, current generates heat at the contact point, leading to the temperature rise, it is generally considered to be equal to ambient temperature plus temperature junction temperature.
2. moisture. Moisture intrusion great influence on the connector insulation, easily corroded metal parts. Damp heat test conditions for the relative humidity at 95% (according to product specifications, up to 98%), the temperature is + 40 ± 20oC, according to the specified test time minimum of 96h. Damp heat test is more stringent.
3. resistant to salt spray. When the connector works in an environment containing moisture and salinity, and its metal structure, the contact surface plating layer is produce galvanic corrosion, affecting the physical and electrical properties of the connector. In order to evaluate the tolerance of the electrical connector of this environment, the salt spray test prescribed. It is the connector hanging in a temperature-controlled test chamber using compressed air discharge with a predetermined concentration of sodium chloride solution to form a salt spray atmosphere, its exposure time defined by product specification, at least 48h.
4. resistant to vibration and shock. Resistant to vibration and shock are important properties of the electrical connector, such as aviation and aerospace, rail and road transport is particularly important in a particular application environment, it is an important indicator of the robustness and electrical test electrical connector contact reliability of the mechanical structure . In the relevant test methods are clearly defined. Shock test should provide peak acceleration, duration and impulse waveform and electrical discontinuity of time.
5. other environmental performance. According to requirements, and other environmental performance as well as tightness (air leak, the liquid pressure), the liquid impregnation of the electrical connector (abuse-resistant capabilities of specific liquids) and low air pressure.
