Description
Technical Field
The present invention relates to fiber optic connectors, and more particularly, to a fiber optic connector that is easily and quickly assembled and disassembled in the field.
Background
In the prior art, the installation process of fiber optic connectors adapted for quick field mating generally includes the steps of: 1) stripping the sheath of the optical cable, stripping the optical fiber protective layer and cutting the optical fiber; 2) inserting the optical fiber of the optical cable into the connector shell and butting the optical fiber of the optical cable with the embedded optical fiber in the connector shell; 3) locking the butted optical cable fibers and the pre-buried fibers; and 4) securing the fiber optic cable to the connector housing.
For the existing optical fiber connector suitable for quick field butt joint, the installation process mainly has the following problems: due to the complex field installation environment, after locking the already spliced optical fibers and before fastening the cable, the cable may be accidentally subjected to a pulling force to pull out the already locked optical fibers of the cable, and in addition, the splicing between the optical fibers may be easily broken in the step of fastening the cable.
In the prior art, the above-described problem occurs because the step of fastening the optical cable is after locking the optical fiber. The butt joint between the optical fibres can be well ensured if the step of securing the cable is before locking the optical fibres.
In addition, when the optical cable fiber and the embedded fiber are butted, in order to ensure that the end surface of the optical cable fiber is reliably contacted with the end surface of the embedded fiber, the optical cable fiber is slightly bent during the butting so as to apply preset extrusion force between the end surface of the optical cable fiber and the end surface of the embedded fiber through proper bending deformation of the optical cable fiber, and thus, the end surface of the optical cable fiber can be ensured to be reliably contacted with the end surface of the embedded fiber. However, in the prior art, after the cable is fastened, the slight bending of the cable optical fiber at the time of the butt joint cannot be released. Therefore, when the optical fiber connector and another optical fiber connector are mated by the optical fiber adapter, the slight bending of the optical fiber cable becomes large (because the optical fiber cable is subjected to the axial pushing force of the spring when the two optical fiber connectors are mated), so that the optical performance of the mated two optical fiber connectors is affected.

In other instances, well-known structures and devices are shown in schematic form in order to simplify the drawing.
According to one general technical concept of the present invention, there is provided an optical fiber connector including: a housing; a ferrule mounted in the housing; a tail sleeve connected to a rear end of the housing; and the optical cable clamp is inserted into the tail sleeve and used for clamping the optical cable. The optical cable is fastened in the optical cable clamp, and after the optical cable clamp is inserted and fixed into the tail sleeve, the optical fibers of the optical cable are inserted into the shell and are butted with the embedded optical fibers in the inserting core.
FIG. 1 shows an exploded schematic view of a fiber optic connector according to an exemplary embodiment of the present invention.
In one exemplary embodiment of the present invention, an optical fiber connector is disclosed. As shown in fig. 1, the optical fiber connector basically includes a housing 100, a ferrule 110 (see fig. 4) mounted in the housing 100, a tail sleeve 200 connected to a rear end of the housing 100, and a cable clamp 300 adapted to be inserted into the tail sleeve 200.
Fig. 2 shows a schematic view of securing the fiber optic cable 10 of the fiber optic connector shown in fig. 1 to a cable clamp 300.
As shown in fig. 1 and 2, a cable clamp 300 is used to hold a cable 10 that is to be processed. Here, the already processed optical cable 10 means: a section of the sheath of the optical cable 10 is peeled off, a section of the protective layer of the optical fiber 11 is peeled off, and the end of the exposed optical fiber 11 is cut and polished.
FIG. 3 shows a schematic view of the insertion of a cable clamp 300, having a cable 10 secured thereto, into the boot 200; fig. 4 shows a longitudinal sectional view of the optical fiber connector shown in fig. 3.
As shown in fig. 1 to 4, after the cable clamp 300 with the optical cable 10 fastened thereto is inserted and fixed into the tail sleeve 200, the optical fiber 11 of the optical cable 10 is inserted into the housing 100 and butted together with the embedded optical fiber 111 in the ferrule 110.
Fig. 5 shows an enlarged view of a portion a of the optical fiber connector in fig. 4, in which the cable optical fiber 11 is pushed by the cable clamp 200 to be bent properly.
In an exemplary embodiment of the present invention, as shown in fig. 1 to 5, a pair of elastic pieces 310 are formed on an outer wall of the cable clamp 300, and a pair of positioning protrusions 211 are formed on an inner wall of the tail sleeve 200. When the cable clamp 300 holding the optical cable 10 is inserted into the tail sleeve 200, as shown in fig. 5, the pair of elastic pieces 310 of the cable clamp 300 respectively abut on the pair of positioning protrusions 211 of the tail sleeve 200 to hold the cable clamp 300 at the first position.

The pair of elastic arms 210 are adapted to be pressed against a pair of elastic pieces 310 of the cable clamp 300, respectively, so as to release the engagement between the elastic pieces 310 and the stopping protrusions 220.
With continued reference to fig. 5 and 6, in the illustrated embodiment, the positioning protrusions 211 are formed on the inner side surfaces of the elastic arms 210, and the positioning protrusions 211 are directly pressed on the elastic sheet 310 when the elastic sheet 310 is pressed by the elastic arms 210.

In one exemplary embodiment of the invention, as shown in fig. 4, the fiber optic connector further includes a dust cap 101 that fits over the front end of the ferrule 110.
As shown in fig. 4, in an exemplary embodiment of the invention, the fiber optic connector further includes a V-shaped alignment slot 102 in the housing 100, and the optical fiber 11 of the fiber optic cable 10 is mated with the embedded optical fiber 111 in the ferrule 110 in the V-shaped alignment slot 102. As shown in fig. 4, the front end portion 11a of the optical fiber 11 of the optical cable 10 and the rear end portion of the embedded optical fiber 111 are received in the V-shaped alignment groove 102, aligned with each other and contacted with each other, thereby achieving optical butt between the optical fiber 11 of the optical cable and the embedded optical fiber 111.

As shown in fig. 5, when the cable clamp 300 is held at the first position, the optical fiber 11 of the optical cable 10 is pushed by the cable clamp 300 to be bent, so that the end face of the optical fiber 11 of the optical cable 10 and the end face of the embedded fiber 111 in the ferrule 110 are reliably butted together.
In an exemplary embodiment according to the invention, the aforementioned assembly method further comprises the steps of:

As shown in fig. 6, when the resilient tab 310 on the cable clamp 300 engages the stop protrusion 220 on the boot 200, the cable clamp 300 is held in the boot 200 at the second position. At this time, as shown in fig. 6, the optical fiber 11 of the optical cable 10 is no longer pushed by the cable clamp 300 to be flat, and the cable clamp 300 cannot be pulled out from the tail jacket 200.
Fig. 8 shows a schematic view of the removal of the fiber optic connector shown in fig. 7 according to an exemplary embodiment of the present invention.

s220: pressing the bosses 210a of the pair of elastic arms 210 inward in the direction of an arrow F1 shown in fig. 8 causes the pair of elastic arms 210 to press against the pair of elastic pieces 310 of the cable clamp 300, respectively, so as to release the engagement between the elastic pieces 310 and the stopper protrusion 220; and
s230: the cable clamp 300 is pulled outward in the direction of arrow F2 shown in fig. 8, causing the cable clamp 300 to be pulled out of the boot 200.
