Description

Technical Field

[0001] The utility model relates to the technical field of connector structures, in particular to a crimping type aviation joint connector structure. Background Art

[0002] A connector is a component used to connect electronic devices, and an aviation plug is one of the connectors. In the field of aviation plugs, the reliability and stability of the plug are crucial, so the crimping method of the connector is very important. At present, the commonly used crimping methods for aviation plugs are mainly crimping and welding.

[0003] Crimping refers to a connection method that uses external force to press the wire and the plug pin tightly together. The advantages of crimping are firm and reliable connection, low contact resistance, and suitable for high-frequency signal transmission. The principle of crimping is to use the elastic deformation of metal to form a close contact surface between the wire and the plug pin, thereby realizing the conduction of current. During crimping, the crimping tool is used to accurately pressurize the wire and the plug pin to make them fit tightly together. The design structure of the crimping connector is complex, but the connection is stable and reliable, and it is not easy to loosen or disconnect.

[0004] Soldering is a connection method that melts and fuses the wire and the plug pin together. The advantages of welding are strong connection, low resistance, and suitability for high temperature and high vibration environments. The principle of welding is to use molten metal to fill between the wire and the plug pin, and form a strong connection through cooling and solidification. Welding requires the use of welding equipment and solder to complete, by heating the wire and the plug pin and applying enough pressure to melt and fuse them together. The design of the welding connector is relatively simple, but the welding process needs to be precisely controlled to avoid unreliable connections caused by overheating or poor welding.

[0005] The existing process usually uses manual welding to connect the wires. It requires manual welding equipment to manually weld the solder joints of the plug and cable. In this process, high-quality solder and welding technology are required to ensure the firmness and reliability of the solder joints. The production efficiency is low and there are requirements for the assembly production site.

[0006] There is a need for a new type of crimping aviation joint connector structure with higher production and assembly efficiency, which can solve the above-mentioned problems. Utility Model Content
