A few tips from the experts on choosing airline sockets

Don't look down on aviation plugs and sockets, their quality is related to the safety of electrical appliances and the user's safety. Expert advice: when buying aviation plugs and sockets should pay attention to a few points: ① pay attention to the brand, to buy the products of large and medium-sized enterprises. These enterprises seriously implement the standards, product quality close. ② pay attention to the logo, the product should have "CCEE" safety certification mark, the product should have the manufacturer's name, address, telephone; standards for rated current regulations, divided into 6A, 10A and 16A three levels, such as other labeling levels are non-standard products. ③ Note that the "match", select the rated voltage, rated current and residential use of wall sockets in line with the product. Rated current from large to small order should be plug, power cord, mobile socket, electrical appliances, can not be reversed. ④ Pay attention to the plug. China's standard plug type for the flat, two-stage and two-stage plug with grounding; cylindrical plug is eliminated products, do not buy. Aviation plug is a more advanced electrical connector products, its material as well as the means of production are using advanced technology at home and abroad. It is made of high-strength aluminum alloy material processing, bayonet type outer groove connection, with a small volume, light weight, easy to use and other advantages. Widely used in electrical equipment and all kinds of instruments, meters between the line connection. The environmental adaptability of the aviation plug should be equal to the sum of the ambient temperature and the temperature rise of the contact. In some specifications, the higher temperature allowed for connectors under rated operating current is also different. When aviation plugs are operated in environments containing moisture and salt, there is a risk of galvanic corrosion of the metal structural parts and surface treatment layer of the contact parts, which may affect the physical and electrical properties of the connector. Aviation plugs at low frequencies, only magnetic materials can play a significant shielding effect on the magnetic field. At this time, there are certain provisions for the electrical continuity of the metal shell, aviation plug, also known as shell contact resistance. It is a process in which the voltage applied to the insulated part of the connector presents a resistance value. Aviation plug voltage withstand refers to the relationship between the contact pair mutual insulating parts or insulating parts and ground. It is particularly important in special application environments such as aviation and aerospace, railroad and road transportation, and it is an important indicator to test the robustness and electrical contact reliability of aviation plugs and connectors structure. Aviation plug electrical strength or voltage withstand, dielectric withstand voltage, is characterized by the connector between the contact parts or between the contact parts and the shell to withstand the rated test voltage.
