The invention discloses a quick butt joint connector which is simple in structure and convenient and quick in butt joint operation. The quick butt joint connector comprises a female connector and a male connector which are connected, wherein the male connector or the female connector can bear high pressure before the male connector and the female connector are in butt joint. The female connector comprises a female valve body with a fluid channel, a core sleeve is positioned in the fluid channel, a choke plug is fixed at one end of a core shaft, the other end of the core shaft penetrates through the core sleeve, a slide sleeve is sleeved on the core shaft, an elastic element is arranged between the slide sleeve and the female vale body or the core sleeve, and the elastic element enables the slide sleeve and the choke plug to be in sealing contact and the core shaft and the core sleeve to be in sealing contact. The male connector a male valve body with a runner, a valve core is positioned in the runner, an elastic part is positioned between the male valve part and the valve core, and the elastic part enables the valve core and the valve seat to be in sealing contact. When one end of the male valve body is inserted into the female valve body, the male valve body can push the slide sleeve to move the distance A, the valve core can push the core shaft to move the distance B, and the B is smaller than the A. Thus, the valve core and the valve seat are not in sealing contact, the choke plug and the slide sleeve are not in sealing contact, the core shaft and the core sleeve are not in sealing contact, and the fluid channel and the runner can form a through channel. Sealing rings are arranged on the core shaft and the valve core, and a location mechanism capable of limiting the male valve body to move is positioned on the female valve body.
