Description

Technical Field

[0001] The present application relates to the field of optical fiber technology, and in particular to an optical fiber connector. Background Art

[0002] When fiber optic cables are brought into homes, a hole is usually drilled in the wall, and then construction workers hold the tail sleeve of the connector and pass the fiber connector through the hole in the wall or through a pre-buried pipe into the house. During the insertion process, the head of the fiber is usually protected to prevent damage to the internal fiber optic ferrule. However, this protection structure is usually only applicable to connectors of a single specification and cannot be applied to connectors of multiple specifications, which is very inconvenient.

[0003] The protective structure is fixed at the end of the optical fiber connector, and the angle is relatively fixed. When the protective structure and the optical fiber connector are pulled through the perforation with a lead, the fiber optic connector pigtail is usually bent or twisted due to the different penetration angles and routing directions, as well as irregular wall perforations. If the bending or twisting angle is too large, the optical fiber will be damaged, posing a hidden danger to transmission.

[0004] The optical fiber ferrule at the head is extremely susceptible to damage or breakage due to friction, impact, etc., and the optical fiber ferrule needs to be replaced later, which increases costs and seriously affects construction efficiency. Utility Model Content

[0005] Based on this, it is necessary to provide a fiber optic connector to overcome the defects in the above-mentioned background technology.

[0006] An optical fiber connector, comprising:

[0007] A connector, one end of which is provided with a socket that is sleeved onto the connector, the socket is provided with a clip arranged around the connector, and the other end of which is provided with a threaded opening that communicates with the socket;

[0008] The protective cover has one end which is detachably connected to the connecting piece through a threaded opening and abuts against the clip, and the other end of the protective cover is provided with a traction head.

[0009] As a preferred embodiment of the optical fiber connector in the utility model, the sleeve is in the shape of an inverted truncated cone, and the diameter of the sleeve at its smallest point is larger than the diameter of the connector.

[0010] As a preferred embodiment of the optical fiber connector in the utility model, the clamp includes a sub-piece, the outer wall of the sub-piece is in contact with the inner wall of the socket, and the inner wall is in contact with the outer wall of the connector, and a plurality of the sub-pieces are combined to form a hollow frustum.

[0011] As a preferred embodiment of the optical fiber connector in the utility model, the protective sleeve has a protective cavity opening downward, and the outer wall at the bottom of the protective cavity is provided with an external thread.

[0012] As a preferred embodiment of the optical fiber connector in the utility model, a fixing piece is provided on the top of the protective cover, and the fixing piece passes through the traction head and is detachably connected to the protective cover.

[0013] As a preferred embodiment of the optical fiber connector in the utility model, the traction head includes a traction seat and a traction buckle, the traction seat is sleeved with a fixing member, the traction buckle is arranged between two side edges of the traction seat, and a traction hole is formed between the traction seat and the traction hole for the traction line to pass through.

[0014] Beneficial effects of the utility model:

[0015] The utility model can rely on the protective cover to protect the optical fiber when the optical fiber connector is to pass through the wiring hole on the wall. The protective cover can also be connected to the traction line to facilitate the passage of the entire optical fiber connector. The connecting piece can be applicable to optical fiber connectors of different specifications. The application range is wide, and it has a good perforation protection effect on the optical fiber, which improves the efficiency of the perforation construction.

[0016] In the utility model, the connector is directly connected to the connector, and the connector can rotate relative to the optical fiber. During the wiring process, when the direction of the optical fiber connector is misaligned with the direction of the traction line, the protective cover can drive the connector to rotate, thereby avoiding twisting of the optical fiber connector tail fiber and improving the safety of threading.
