Technical Field

[0001] The invention relates to the technical field of optical fiber cables, and in particular to a novel point spectrum probe optical fiber cable. Background Art

[0002] At present, the optical fiber cable of the point spectrum probe is a relatively mature product, and the general structure is: standard FC connector + optical fiber cable + standard FC connector. The optical fiber cable with this structure still has the following problems: 1. The exposed ferrule is easily contaminated; 2. The FC interface is easily contaminated, and the transmission of the light beam received and received at the controller end is greatly affected by the contamination of the ferrule; 3. The background light level is unstable, and dark calibration needs to be performed frequently; 4. The optical fiber ferrule has an 8-degree bevel angle. In order to make the central axis of the light output coincide with the central axis of the probe, the probe mounting base and the probe need to be assembled at an angle, which affects the appearance and is inconvenient to operate.

[0003] Based on the above background, the present invention has developed a new type of optical fiber cable. The new cable adopts an innovative connector and integrates the coupler into the optical fiber line end. The controller end interface is less affected by dirt, and a new connector that is not easy to get dirty is designed at the probe end. The light output axis is horizontal with the optical fiber axis, which solves the above problems of current standard optical fiber cables. Summary of the invention

[0007] Furthermore, the single / multi-light-spot connector includes a ferrule pressing seat and a ferrule mounting seat, a fiber optic ferrule is inserted into the ferrule pressing seat, the fiber optic ferrule is inserted into a slot of the ferrule mounting seat and fixed, the ferrule pressing seat and the ferrule mounting seat are screwed together by threads, and the D-shaped surface end of the ferrule mounting seat is inserted into the corresponding D-shaped hole of the fiber optic connector connection seat to complete the connection.

[0008] Furthermore, the slot of the ferrule mounting seat is tilted to facilitate the rotation and change of the installation angle of the optical fiber ferrule so that the center axis of the light output coincides with the center axis of the connector.

[0009] Furthermore, a knob is sleeved on the outer side of the ferrule pressing seat, and the knob and the optical fiber connector connection seat are screwed together through threads.

[0010] Furthermore, a connector end protruding outward is provided on the end of the ferrule mounting seat opposite to the optical fiber connector connecting seat, the connector end is connected to the slot of the ferrule mounting seat, and a protective window sheet is attached to the connector end.

[0011] Furthermore, the optical fiber ferrule is an APC optical fiber ferrule or an MT multi-light-spot ferrule.
