ABSTRACT:
FIELD OF THE INVENTION
The invention relates to an improved connector for a fiber optic cable, especially to a connector which is able to clamp the inner cover of the fiber optic cable in order to provide better constriction of the movement of the fiber optic cable than the conventional one.
BRIEF DESCRIPTION OF THE RELATED ARTS
Conventional fiber optic connectors are liable to become loose with respect to the fiber optic filament contained therein. To overcome such a problem, an improved connector is introduced. In this connector, multiple transverse slits are provided. Multiple corresponding clamps each having a central opening defined therethrough are respectively located in each corresponding slit. Thereafter, the clamps are able to clamp the respective fiber optic cable inserted into the central openings of the connector.
The conventional connector is improved, though, it still has drawbacks since the clamps only clamp the outer cover of the fiber optic cable. The inner cover of the fiber optic cable is not directly constricted with respect to the connector so the fiber optic filament, to a certain degree, is still able to move. That sometimes causes inaccurate alignment of two fiber optic filaments when two connectors are needed to be joined together. This may in turn cause the degradation, disruption and/or loss of the signals transmitted between the two fiber optic filaments. To rectify the defect, U.S. Pat. Nos. 5,301,250 and 5,590,230 introduce a manner to align two fiber optical wire. Still, the filament of the optical wire can not be accurately aligned with one another even though the situation of alignment between two different fiber optical wire is improved.
The present invention aims to provide an improved fiber optical connector to obviate and/mitigate the aforementioned problems.
SUMMARY OF THE INVENTION
The main objective of the invention is to provide an improved fiber optic connector, which is able to provide a stronger connection between the connector to the fiber optic filament contained therein than the existing connectors.
Another objective of the invention is to provide an improved fiber optic connector, which is able to prevent any deviation of the fiber optic filament when in alignment with another one, thus provide accurate alignment for the two fiber optic filaments.
Yet another objective of the invention is to provide an improved fiber optic connector in which a cover with a button means is provided in order to protect the connector and the fiber optic filament contained therein from dust and vapor.
