Abstract
The invention relates to an optical fiber coupling connector. The optical fiber coupling connector comprises a shell, a coupling part and an elastic part arranged in the shell, wherein the coupling part is used for coupling different optical fibers so as to realize transmission of optical signals among the different optical fibers; the coupling part comprises an accommodating end accommodated in the shell; the shell comprises an inner side surface opposite to the accommodating end; the elastic part comprises at least two elastic pieces positioned between the inner side surface and the end face of the accommodating end; and the elastic pieces are elastically pressed against the inner side surface and the end face of the accommodating end uniformly. As the at least two elastic pieces for providing uniform elastic forces are arranged between the inner side surface and the end face of the accommodating end, inclination of the optical fiber coupling connector relative to the shell during connection with other connectors due to a non-uniform stress on the coupling part during insertion can be avoided; therefore, the transmission efficiency of the optical fiber can be improved.
