Hardened multicore connector and fiber optic connector

A hardened multicore connector, configured to detachably connect to a fiber optic connector, wherein the hardened multicore connector comprises a main body, a buffer member, a fiber optic assembly and a housing sequentially connected, wherein:

• the main body is detachably connected to the housing, and the fiber optic assembly and the buffer member are sleeved therein, so that the fiber optic assembly and the buffer member are fixed between the main body and the housing to limit an axial movement among the main body, the fiber optic assembly, the buffer member and the housing;
• a limiting structure is provided in the housing, and the limiting structure is configured to engage with the fiber optic assembly to limit a circumferential rotation of the fiber optic assembly;
• and
• the main body is provided with a first abutting portion, an outer sidewall of the fiber optic assembly is provided with a second abutting portion, the buffer member is fixed between the main body and the fiber optic assembly, and two end surfaces of the buffer member respectively abut against the first abutting portion and the second abutting portion, so that when the hardened multicore connector is aligned with and connected to the external fiber optic connector, the external fiber optic connector pushes the fiber optic assembly to axially move to enable the buffer member to deform, and therefore the hardened multicore connector is flexibly connected to the external fiber optic connector.
