The jacks used in aviation plugs are ordinary jacks and wire spring jacks. These two jacks are different in manufacturing process, so do they play different roles? Now let's follow the editor to see the difference between the wire spring jack of the aviation plug and the ordinary jack.


　　A plurality of elastic gold-plated or silver-plated metal wires are arranged in a straight bus bar of a single leaf revolving hyperboloid in the wire spring jack of the aviation plug, and then formed by forming an angle with the inner straight bus bar. When the pin is inserted into the hole and contacts with multiple independent wire spring wires, multiple independent current paths are formed, and the wire spring wires will be elastically deformed in the radial and axial directions.

　　Since the wire spring jack uses multiple wire spring wires, even if some of the wire spring wires are broken, the wire spring hole can still form an effective current path, so it has high insertion and extraction force and reliability, and contact resistance Also small. The contact resistance is not only small but also stable, because when the aviation plug pin is inserted into the jack, these elastic metal wires will be tightly surrounded around the pin to form a multi-line contact. A pair of pinholes can be used as several pairs of ordinary pins and holes. Used in parallel. At the same time, it also greatly improves the contact reliability. It has the advantages of low insertion and extraction force, low contact wear and long insertion and extraction life. In the environment of strong vibration and shock, it can still maintain high reliability of electrical contact. It is widely used in aerospace. , Medical equipment, electronic communications, smart equipment, automotive electronic testing and weapons equipment and other fields.


　　The workmanship of ordinary jacks is not as exquisite as wire spring jacks. The workmanship is relatively simple. The surface is treated with gold plating, silver plating, tin plating and nickel plating. The diameter can range from 0.5 mm to 20 mm. It is mainly used for military connectors, The connectors of medical connectors and computer connectors have good contact and many plug-in times, which can effectively ensure product quality and durability.
