Abstract
The invention relates to a novel optical fiber connector which comprises a ceramic ferrule, a tail handle of the ferrule, a spring, an optical fiber and an SC opened clamping sleeve. The tail handle of the ferrule is connected with the rear end of the ceramic ferrule. An end portion of the optical fiber penetrates through the tail handle of the ferrule to be connected with the ceramic ferrule. The spring is sleeved on the tail handle of the ferrule. The front end of the spring is abutted against an annular convex rig of the front end portion of the tail handle of the ferrule. The SC opened clamping sleeve is a cylinder-shaped structure part with a C-shaped cross section. A round penetrating cavity is arranged in the middle of the SC opened clamping sleeve. An optical entrance which is communicated with the penetrating cavity and extends in the length direction of the SC opened clamping sleeve is arranged in a side face of the SC opened clamping sleeve. The front half part of the SC opened clamping sleeve is an octagon-shaped cylinder. At least two clamping keys are arranged on the outer side of the octagon-shaped cylinder. A C-shaped clamping rim is arranged in the penetrating cavity. End portions of the ceramic ferrule, the tail handle of the ferrule, the spring and the optical fiber are all arranged in the penetrating cavity. The rear end of the spring is abutted against the C-shaped clamping rim. The novel optical fiber connector is simple in structure, little in size, little in machining difficulty and low in cost.
