Abstract
The utility model discloses a prefabricated formed butterfly-shaped optical cable connector which comprises a neck bush, an outer frame sleeve, a ceramic mortice, a metal caudal peduncle, a stop casing, a butterfly-shaped optical cable, a tail cover and a spring. A clamping member used for chucking the butterfly-shaped optical cable is arranged between the rear end of the stop casing and the butterfly-shaped optical cable. a front part of the corresponding end of the butterfly-shaped optical cable is stripped to form a bare fiber section at the front end and a coated fiber section positioned at the back portion of the bare fiber section. The bare fiber section is all inserted in the ceramic mortice. The front end of the coated fiber section is inserted in the metal caudal peduncle and is fixed by glue joint. Residual part of the coated fiber section penetrates through the stop casing. When the butterfly-shaped optical cable connector is in butt joint with another connector through an adapter, the ceramic mortice and the metal caudal peduncle indent inwardly, and the spring is compressed. Meanwhile, the coated fiber section which penetrates through the stop casing is bent under stress. By the utilization of the G657 fiber bending insensitivity characteristic of the butterfly-shaped optical cable, a certain bending of the optical cable is allowed so as to counteract length changes of the mortice.
