What are the environmental requirements for the use of aviation plugs?

Aviation plug belongs to one kind of low-frequency multi-contact connector, which originates from the military industry and is also referred to as aviation plug. According to their own electrical parameters to select the appropriate specifications and models is the first thing to consider, the correct choice and use, in order to protect the safety and reliability of the circuit. If you want to choose and use correctly, you must master the requirements of the plug on the use of the environment.　　Aviation plug has a wide range of applications, especially in equipment manufacturing, information and control technology, industrial systems, buildings and industrial automation in the field of frequent use. They are used in electrical circuits to connect or disconnect circuits. The plug on the use of the environment puts forward the following requirements: 1, moisture or water: moisture or water will affect the insulation properties, so that the insulator surface has a water film formation, resulting in a decline in the performance of the insulation, and in serious cases, may even cause the two adjacent contacts to appear false conduction situation. Usually, if the user needs to use the connector in a long time in high humidity or in the environment of water, it should be used with a sealed waterproof function of the plug.　　2, ambient temperature: the plug should be used in the specified ambient temperature, generally in the use of instructions to indicate the use of the ambient temperature range, some times, the external ambient temperature is not high, but the plug needs to work in the cabinet, once the cabinet's heat dissipation conditions are poor, it will lead to the use of plugs in the ambient temperature is too high, resulting in the plug's metal coating and the insulator is damaged.　　3, corrosive environment: mainly refers to the plug work around the environment, such as the sea environment will have salt spray, storage of large quantities of chemical raw materials in the warehouse have acid and alkali components, etc., these environmental conditions will be on the plug in the metal parts, insulator parts caused by corrosion and erosion, so these corrosive environments in the choice of plug, you can put forward to the manufacturer of the special requirements in order to plug to meet the environmental conditions. 4, low air pressure.　　4, low air pressure: plug in the high-altitude conditions will be reduced because of air pressure and performance (except for the constant air pressure sealing ring territory), when the plug is in low air pressure conditions, the medium voltage will drop, if the voltage required to transmit significantly more than the joint itself technical requirements, may lead to electrical breakdown accidents.　　5, mechanical conditions: according to the parameters of the plug to select the vibration, shock and acceleration and other aspects of the mechanical effects. In the actual use of the process, if the line is too large and did not take fixed measures, then in the vibration, impact and other external forces, will affect the safety of the line, and in serious cases will even cause line breakage, plug damage and other failures. Plugs on the use of the environment is required, before use, should be carefully studied the technical parameters of the plug and the use of the requirements of the plug in the plug allows the use of the environment.　　Improving the reliability of aviation plugs is an important responsibility of manufacturers, but since there are quite a variety of plugs on the market with a wide range of applications, the correct selection of plugs is also an important aspect of improving the safety of their use.
