Abstract

A socket structure includes a frame body, a partition portion and an engaging arm. The partition portion is disposed in the frame body. The engaging arm includes an arm portion and a hooking portion. The arm portion extends from the partition portion. The hooking portion is formed at a free end of the arm portion for engaging with an optical fiber connector so that the optical fiber connector is fixed. The hooking portion includes a first flat surface and a second flat surface. The first flat surface extends away from a first direction at an acute angle. The second flat surface is provided between the first flat surface and the arm portion. When the optical fiber connector is inserted into the socket structure in the first direction, a protrusion of the optical fiber connector pushes the hooking portion so that the arm portion is deformed. When the protrusion passes by the first flat surface, the first flat surface and the protrusion have a surface contact therebetween.
