Waterproof aviation plug and socket is a kind of water-proof, cold resistant, stable performance and high-efficiency quick connector.
Do not underestimate the waterproof aviation plug, their quality is related to the safety of electrical appliances and the safety of users.
Experts suggest: pay attention to the following points when purchasing waterproof aviation plug and socket:
① Pay attention to the brand and choose the products of large and medium-sized enterprises. These enterprises seriously implement the national standards, product quality close.
② Pay attention to the identification, the product should have the 'CCEE' safety certification mark, and the manufacturer's name, address and telephone number should be on the product; the national standard for the rated current is divided into 6a, 10a and 16A three levels, if there are other marking levels, they are non-standard products.
③ Pay attention to 'matching' and select the products with rated voltage and current consistent with wall socket used in residence. The order of rated current from large to small should be plug, power line, mobile socket and electric appliance, and can't be reversed.
④ Pay attention to the plug. According to the national standard of our country, the plug type is flat, with two-stage and two-stage plug with grounding; the cylindrical plug is an obsolete product and should not be purchased.
Waterproof aviation plug is a kind of advanced electrical connector products, its material and production means are using advanced technology at home and abroad. It is made of high strength aluminum alloy material and connected by bayonet type outer groove. It has the advantages of small volume, light weight and convenient use. It is widely used for the line connection between electrical equipment and various instruments. The environmental adaptability of waterproof aviation plug should be equal to the sum of ambient temperature and contact temperature rise. In some specifications, the maximum allowable temperature of the connector at rated operating current is also different.
When the waterproof aviation plug works in the environment containing moisture and salt, the surface treatment layer of its metal structure and contact may produce electrochemical corrosion, which will affect the physical and electrical properties of the connector. In low frequency, only magnetic material can shield the magnetic field obviously. At this time, there are certain provisions on the electrical continuity of the metal shell, aviation plug is also the contact resistance of the shell. It refers to the process of applying voltage to the insulation part of the connector and showing resistance value.
The withstand voltage of waterproof aviation plug refers to the relationship between the contact pair and the insulated part or between the insulated part and the grounding. It is particularly important in the special application environment, such as aviation and aerospace, railway and highway transportation. It is an important index to check the structural firmness and electrical contact reliability of aviation plug and connector. The electrical strength of waterproof aviation plug, or voltage withstand or dielectric withstand voltage, is the ability to withstand rated test voltage between connector contacts or between contacts and enclosure.
