What is the connector aviation plug? What are the parts?

1. Aviation plug contact body It is usually formed by cutting or non-cutting method. Cylindrical pin and socket structure is simple, reliable contact, easy to process into a variety of specifications, so it is widely used.2. Insulator Aviation plug insulator fixed contact body insulation, in addition to ensure that multiple contacts between each other electrical insulation, but also play a role in guiding, positioning, sealing and so on. Insulator material and structure directly affect the electrical and mechanical properties of the aviation plug. According to the hardness of the material, there are flexible insulators, semi-hard insulators and hard insulators. Commonly used materials include rubber, plastic, ceramic and glass.3. Shell The aviation plug shell fixes and protects the structure of the insulator and contact body. Shell on the positioning, guiding, locking mechanism to ensure that the aviation plug can work properly. Shell sometimes also play a sealing, waterproof, fire and electric field shielding role. Circular connector shell with screws, bayonet and straight self-locking self-locking type, easy to connect in the case of multi-contact and large insertion and extraction force.

-What are the connection methods of aviation connector plugs and sockets? 1. Threaded connection is the most common. It has the advantages of simple processing, low manufacturing cost, wide range of application, but the connection speed is slow, not suitable for occasions that require frequent insertion and removal and fast connection; 2. Bayonet connection of the three bayonet slots of the lead is longer, so the connection speed is faster, but the manufacturing is more complex and costly; 3. Push-pull connection is the fastest connection among the three connection methods. There is no need to rotate, just move in a straight line to realize the connection, separation and locking function. Because it is a direct push-pull connection, it is only suitable for aviation plugs with small total separation force. It is usually found in small aviation plugs.
