Abstract
An optical fiber connector is used for accommodating optical fibers. The optical fiber connector comprises a housing which comprises a top surface and forms an accommodating space from the top surface. The housing further comprises a bottom wall which is adjacent to the accommodating space and away from the top surface. The bottom wall is provided with trenches, first accommodating grooves, and clamping holes. The first accommodating grooves and the trenches are communicated with each other in a one-to-one correspondence manner, and the axis of each first accommodating groove is aligned with the axis of the corresponding trench. The optical fiber connector further comprises a clamping buckle. The clamping buckle comprises a cantilever beam and clamping hooks extending from the cantilever beam. The cantilever beam has a bottom surface, and second accommodating grooves are formed in the cantilever beam from the bottom surface. The clamping buckle is accommodated in the accommodating space. The clamping hooks extend into the clamping holes to fix the clamping buckle to the housing. The first accommodating grooves and the second accommodating grooves jointly form accommodating holes. The trenches and the accommodating holes are jointly used for accommodating optical fibers.
