At present, the electrical connector in the application of life has become increasingly widespread. As such devices are smaller, more sophisticated design, in the use of often appear in various situations. For some common faults, we also need to do the appropriate analysis of work, and want to solve the solution:
① temperature The current connector of the maximum operating temperature of 200 ℃ (except for a few high temperature special connector), the minimum temperature of -65 ℃. As the connector is working, the current at the contact point to generate heat, resulting in temperature rise, it is generally believed that the operating temperature should be equal to the ambient temperature and contact temperature rise and. In some specifications, the maximum permissible temperature rise of the connector at rated operating current is specified.
② moisture-resistant moisture intrusion will affect the connection h insulation properties, and corrosion metal parts.
③ salt spray connector in the environment containing moisture and salt work, the metal structure, the contact surface treatment layer may produce electrochemical corrosion, affecting the physical and electrical properties of the connector.
④ vibration and shock resistance to vibration and shock is an important performance of electrical connectors, in special application environments such as aviation and aerospace, railway and road transport is particularly important, it is to test the mechanical structure of the electrical connector robust and reliable electrical contact An important indicator of sex.
⑤ other environmental performance According to the use of requirements, other environmental performance of the electrical connector also have sealing (air leakage, liquid pressure), liquid immersion (for specific liquid resistance to habitual capacity), low pressure and so on.
