[0025] The following will further describe the specific embodiments of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0026] As Figures 1-6 shown, the optical fiber assembly for facilitating detection of the present utility model includes an optical fiber body 1. The optical fiber body 1 includes a communication optical fiber 11. The communication optical fiber 11 includes a communication main body section 111 and communication extension sections 112 integrally connected to both ends of the communication main body section 111. One end of the communication extension section 112 away from the communication main body section 111 is used to connect to the communication joint 2: Detection branch sections 12 are also integrally connected to both ends of the communication main body section 111.

[0027] The optical fiber body 1 of the present utility model mainly consists of two parts. One is the communication optical fiber 11, and the other is the detection branch section 12. The communication optical fiber 11 mainly includes a communication main body section 111 and communication extension sections 112 integrally connected to both ends of the communication main body section 111. At both ends of the communication optical fiber 11, that is, one end of the two communication extension sections 112 away from the communication main body section 111 is connected to the communication joint 2. By inserting the communication joint 2 into the communication interface of the communication device, fiber optic communication between communication devices can be achieved. And a detection branch section 12 is provided at the integral connection part of the communication main body section 111 and the communication extension section 112. When detecting the communication optical fiber 11, it is not necessary to unplug the end of the communication optical fiber 11. Only need to use an optical fiber test pen to select and connect to one of the detection branch sections 12, and detect whether there is an optical fiber signal transmitted from the other detection branch section 12, then it can be judged whether the communication optical fiber 11 is used normally. If there is an optical fiber signal, it means that the communication optical fiber 11 is used normally. If there is no optical fiber signal, it means that the communication optical fiber 11 is abnormal.

[0028] Therefore, for the optical fiber component of the present utility model, the detection operation can be completed without unplugging the end of the communication optical fiber 11 during detection, ensuring that normal signal transmission can still be carried out between communication devices through the communication optical fiber 11 when the communication optical fiber 11 is normal, thus making the detection operation more convenient.

[0029] A further improvement is that an optical ferrule 5 is connected to one end of the detection branch section 12 far from the communication main body section 111. Specifically, a ferrule base 51 is provided at one end of the optical ferrule 5 adjacent to the detection branch section 12, and the ferrule base 51 is connected to the detection branch section 12. The optical ferrule 5 is a ceramic optical ferrule 5. After adopting the above structure, it is convenient to dock the optical fiber test pen with the optical ferrule 5 when detecting the communication optical fiber 11.

[0030] A further improvement is that the optical fiber component of the present utility model further includes a protective isolation sleeve 3. The protective isolation sleeve 3 is sleeved outside the communication optical fiber 11, and an opening 31 for the detection branch section 12 to pass through is provided on the side wall of the protective isolation sleeve 3.

[0031] By providing the protective isolation sleeve 3, the physical integrity of the communication optical fiber 11 can be ensured, the possibility of breakage can be reduced, the tensile strength can be improved, the moisture-proof sealing of the communication optical fiber 11 can be achieved, the lateral pressure resistance can be enhanced, thereby enhancing the environmental adaptability. In addition, the functions of flame retardancy, wear resistance and electromagnetic interference prevention for the communication optical fiber 11 can also be realized, thus improving the safety of using the communication optical fiber 11; by providing the opening 31 on the side wall of the protective isolation sleeve 3, it is convenient for the detection branch section 12 to extend out of the protective isolation sleeve 3 and be connected to the optical ferrule 5.

[0032] A further improvement is that the optical fiber component of the present utility model further includes a hollow protective shell 4. The protective isolation sleeve 3 is hermetically passed through the inside of the protective shell 4, the detection branch section 12 is arranged inside the protective shell 4, the optical ferrule 5 is passed through one side wall of the protective shell 4, and in addition, the opening 31 is arranged inside the protective shell 4.

[0033] After adopting the above structure, the detection branch section 12 can be isolated and protected by the protective shell 4, preventing it from being exposed to the outside air, and is beneficial to fixing the position of the protective isolation sleeve 3 near the communication joint 2 and the position of the optical ferrule 5.

[0034] A further improvement is that the protective shell 4 includes a first shell 41 and a second shell 42 which are detachably connected.

[0035] In the present utility model, the protective shell 4 is mainly formed by detachably connecting the first shell 41 and the second shell 42. During assembly, the communication optical fiber 11 is passed through one of the first shell 41 and the second shell 42, then the optical ferrule 5 and the detection branch section 12 are laid, and then the first shell 41 and the second shell 42 are connected to form the protective shell 4, thus realizing the protection of the detection branch section 12.

[0036] For the convenience of assembly and the laying of optical fibers, in the present utility model, a first wiring groove 411 and a first socket groove 412 extending along the length direction of the first housing 41 are provided on the first housing 41, and a second wiring groove 421 and a second socket groove 422 extending along the length direction of the second housing 42 are provided on the second housing 42. Both the first wiring groove 411 and the second wiring groove 421 are through grooves and are combined to form a wiring channel for the protective isolation sleeve 3 to seal and pass through. One end of the first socket groove 412 extends to the outer side wall of the first housing 41, and the second socket groove 422 extends to the outer side wall of the second housing 42. The first socket groove 412 and the second socket groove 422 are combined to form a socket channel, and the circumferential inner wall of the socket channel is hermetically connected to the circumferential outer edge of the ferrule 5. By adopting the above design, the laying of the protective isolation sleeve 3 and the ferrule 5 is facilitated.

[0037] A further improvement is that a convex portion 413 and a concave portion 423 for plug-in cooperation are provided between the first housing 41 and the second housing 42, and the plug-in cooperation direction of the convex portion 413 and the concave portion 423 is parallel to the notch orientation of the first wiring groove 411. Specifically, the convex portion 413 and the concave portion 423 are respectively provided on the first housing 41 and the second housing 42. During assembly, by inserting the convex portion 413 into the concave portion 423, the first housing 41 and the second housing 42 can be connected to form the protective housing 4, thus facilitating assembly.

[0038] A further improvement is that the protective housing 4 further includes a connecting member 43, and both sides of the connecting member 43 are respectively connected to the first housing 41 and the second housing 42. Specifically, the connecting member 43 is a connecting sheet material, and both sides are respectively connected to the first housing 41 and the second housing 42. By providing the connecting member 43, the first housing 41 and the second housing 42 can be connected to prevent them from separating and being lost.

[0039] A further improvement is that the length of the communication extension section 112 is within 10 cm. By adopting this design, the length of the communication extension section 112 is shortened, ensuring that the length of the communication main body section 111 is much greater than the length of the communication extension section 112, so that there is a sufficient length distance for the communication main body section 111 between the two detection branch sections 12, ensuring the detection range length of the used part of the communication optical fiber 11.

[0040] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
