I. What properties are included in the environmental performance of straight-through connectors? The general environmental performance of straight-through connectors includes temperature resistance, humidity resistance, salt spray resistance, vibration and shock resistance. (1) The current connector's higher operating temperature of 200 ℃ (in addition to a few high-temperature special connectors), the lower temperature of -65 ℃. It is considered that the operating temperature should be equal to the sum of the ambient temperature and the contact temperature rise. In some specifications, connectors are specified at rated operating current. Higher temperature rise. (2) Moisture and moisture intrusion can affect the insulating properties of H and corrode metal parts. Constant humidity and heat test conditions of 90% to 95% relative humidity (98% according to product specifications), temperature +40.(3) Salt spray resistant connectors work in a humid, salt-containing environment, the metal structure and the surface treatment layer of the contact parts will produce galvanic corrosion, affecting the physical and electrical properties of the connector. In order to evaluate the ability of HTK Hondo straight-through connectors to withstand this environment, a salt spray test is provided. It suspends the HTK Hondo straight-through type connector in a temperature-controlled test chamber and dissolves it with a specified concentration of sodium chloride. The liquid is ejected with compressed air to create a salt spray atmosphere. The exposure time is set by the product specification for at least 48 hours. (4) Vibration and shock resistance are important properties of electrical connectors, especially in aerospace, railroad, road transportation and other special applications. It is an important indicator for testing the reliability of the mechanical structure and electrical contact of the electrical connector. The relevant test methods have clear provisions. Peak acceleration, duration and shock should be specified in the shock test.
