Claims
- 1. A pre-assembled optical fiber connector comprising a boot, a sleeve, a spacing sleeve, a tubular housing, a spring, an alignment ferrule, a push-pull insulative housing and a push-pull element which are assembled in series, characterized in that the alignment ferrule has at least one resilient engaging portion to engage the tubular housing so that the tubular housing, the spring and the alignment ferrule are pre-assembled.
- 2. A pre-assembled optical fiber connector as claimed in claim 1, wherein the alignment ferrule further has a ring from which the resilient engaging portion protrudes.
- 3. A pre-assembled optical fiber connector as claimed in claim 2, wherein the alignment ferrule is substantially cylindrical, and the resilient engaging portion is bent in the radial direction of the alignment ferrule when the resilient engaging portion is squeezed.
- 4. A pre-assembled optical fiber connector as claimed in claim 3, wherein the alignment ferrule further has a circumferential groove in which the ring is disposed.
- 5. A pre-assembled optical fiber connector as claimed in claim 1, wherein the alignment ferrule further has a stop flange; the tubular housing has communicating first, second and third holes inside; the inner diameter of the second hole is smaller than the inner diameters of the first and third holes so that a first interface is formed between the first and second holes, while a second interface is formed between the second and third holes; the spring is compressed between the stop flange and the first interface, while the resilient engaging portion of the alignment ferrule engages the second interface between the second and third holes.
