Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically a threaded aviation connector. Background Technology

[0002] Aviation electrical connectors, including aviation sockets and plugs, are named for their initial application in the aviation field. They are now widely used in high-reliability applications such as aerospace, defense, power, and industrial equipment. Aviation sockets and plugs typically have insulators and insulator covers for easy fixing of pin contacts and socket contacts. Currently, the insulators and insulator covers in aviation plugs and sockets still use a planar connection method. When fixing contacts in this way, the actual distance between the contacts along the insulating surface is short, resulting in a short creepage distance. Under unstable voltage, this can easily create conductive paths between contacts, leading to leakage or equipment damage. Furthermore, the cables on aviation plugs are usually sealed with a sealing sleeve. In actual use, when operators pull the plug out by dragging the cable, the connection between the cable and the contact can easily break, causing damage to the plug. Utility Model Content
