Product Details
Aviation plug is a kind of connector, from the military industry, hence the name, referred to as air plug. Aviation plugs are electromechanical components that connect electrical circuits, so their own electrical parameters are the first to consider when choosing aviation plugs. The correct selection and use of aviation plugs is an important aspect to ensure the reliability of the circuit.
Aviation plug can also be called plug socket, widely used in various electrical circuits, plays the role of connecting or disconnecting the circuit. Improving the reliability of aviation plugs is first and foremost the responsibility of the manufacturer. However, due to the wide variety of aviation plugs and a wide range of applications, the correct selection of aviation plugs is also an important aspect of improving the reliability of aviation plugs. Only through the joint efforts of both the manufacturer and the user can the function of the aviation plug be maximized. Aviation plugs have different classification methods. According to the frequency, there are high-frequency aviation plugs and low-frequency aviation plugs. According to the shape, there are circular connectors. According to the purpose, there are aviation plugs for cabinets, aviation plugs for audio equipment, aviation plugs for power supplies, aviation plugs for special purposes, etc. The following mainly discusses the selection method of low-frequency aviation plug (frequency below 3MHZ).
Contact pressure is an important indicator in aviation plugs, which directly affects the size of the contact resistance and the amount of wear of the contact pair. In most configurations, it is quite difficult to measure contact pressure directly. Therefore, the contact pressure is often measured indirectly by the single foot separation force. For circular pinhole contact pairs, standard pins with specified weight weights are usually used to test the ability of the female contact to hold the weight. Generally, the diameter of the standard pin is-5μm from the lower limit of the diameter of the male contact. The total separation force is generally twice the sum of the upper lines of the single foot separation force. When the total separation force exceeds 50N, it is already quite difficult to insert and unplug manually. Of course, for some test equipment or some special requirements of the occasion, can choose zero insertion force aviation plug, automatic drop aviation plug and so on.
