The invention discloses an aviation connector facilitating the assembly and disassembly of a terminal, and the connector comprises a core insulating part, a terminal and a rubber core support sleeve.A side wall of the core insulating part is provided with a terminal installation groove and a holding-on structure is disposed in the terminal installation groove. The terminal is provided with a buckling groove adapted to the holding-on structure. The rubber core support sleeve is disposed outside the core insulating part in a sleeving manner, and then is in clamping connection with the core insulating part. The bottom of the rubber core support sleeve is provided with a terminal installation through hole corresponding to the terminal installation groove. The terminal installation groove of the core insulating part and the inner wall of the rubber core support sleeve are assembled to form an enclosing hole cavity for fixing the terminal. The terminal is fixed on the core insulating par through the holding-on structure, and then the core insulating part is installed in the rubber core support sleeve. After the rubber core and the rubber core support sleeve are separated, the terminal can be taken down easily, so as to achieve the disassembly of the terminal on the aviation connector without a special tool and achieve the disassembly of the terminal on the aviation connector, thereby saving the disassembly time and improving the assembly and disassembly efficiency.
