[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0019] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0020] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a quick-connection optical fiber jumper of the utility model comprises an optical fiber jumper body 1, both ends of the optical fiber jumper body 1 are installed with connectors 5, the outside of the connectors 5 are sleeved with a protective shell that seals the connectors 5, the middle of the protective shell is composed of two half shells 2, one end of the half shells 2 is provided with an arc groove, adjacent arc grooves are combined to form a mounting hole, a rotating cylinder is installed in the mounting hole, a cleaning layer 7 is installed inside the rotating cylinder, adjacent cleaning layers 7 are combined to form a cleaning cavity, and the plugs on the connectors 5 are inserted into the cleaning cavity.

[0022] In this embodiment, the rotating cylinder is composed of two half cylinders 3, and the inner ring surface of the arc groove is provided with an arc-shaped connecting groove, and adjacent connecting grooves are combined to form a connected annular groove. The opening end surfaces of adjacent half cylinders 3 are abutted against each other, and the outer ring surface of the half cylinder 3 is protruded to form a connecting part 6 with an arc structure, and adjacent connecting parts 6 are combined to form a positioning ring, and the positioning ring is slidably installed inside the annular groove.

[0023] In this embodiment, a plurality of positioning parts are protruded on the open end surface of the upper half cylinder 3, and a positioning groove 8 is provided on the open end surface of the lower half cylinder 3 opposite to the positioning part. The positioning parts are inserted into the positioning groove 8, so that the half cylinders are arranged relative to each other, avoiding misalignment between the half cylinders and increasing stability.

[0024] In this embodiment, fixing plates 4 are installed at both ends of the fiber jumper body 1 near the connector 5. The fixing plates 4 extend into the interior of the protective shell, and the fixing plates 4 and the half shell 2 are fixedly connected by torsion spring hinges.

[0025] In this embodiment, the cleaning layer 7 is made of ultra-fine fibers with extremely fine fiber diameters, which are only 1 / 100 of a hair and 1 / 20 of ordinary fibers. They can absorb dust into the fiber gaps and remove fine dust particles. They are soft in texture and have good dust removal effects.

[0026] In this embodiment, the cross-sections of the connecting groove and the connecting part 6 are both arranged in a trapezoidal structure, so that the connecting part can only rotate along the connecting groove, avoiding direct separation from the connecting groove, wherein a frictional interference is arranged between the connecting part and the connecting groove, so that the rotating cylinder or half cylinder can be positioned after rotation.

[0027] When in use, the rotating cylinder can be turned until the connecting part on the upper half cylinder is located in the upper connecting groove and the connecting part on the lower half cylinder is located in the lower connecting groove, thereby avoiding the inability to open due to misalignment. At this time, the half shell is opened outwards so that the connector can be exposed, which is convenient for plugging the connector with the equipment.

[0028] After the connector is pulled out of the device, the half shells can be quickly and automatically closed by twisting the torsion spring hinge, and the connector can be covered and sealed by the upper and lower closed half shells, greatly reducing the probability of dust contacting it, and the plug on the connector can enter the cleaning chamber. After rotating the rotating cylinder, the rotating cylinder can drive the cleaning layer, and the friction between the cleaning layer and the plug can quickly remove dust and impurities on the plug, avoiding affecting the subsequent connection quality, and after the rotating cylinder rotates, the connecting parts can be distributed left and right in the annular grooves, and the half shells can be positioned by the dislocated connecting parts, avoiding the half shells from opening by themselves, and the half shells can effectively block external impacts, avoiding the connector from being damaged due to direct impacts.

[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
