DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0024] Embodiment 1

[0025] Reference Figures 1 to 3 As shown, an optical fiber connection device of the present invention comprises: a connecting cable 1, wherein a plurality of optical fiber components 7 are arranged inside the connecting cable 1; a first branch component 2, wherein one end of the first branch component 2 is connected to the connecting cable 1, and the other end of the first branch component 2 is detachably connected to at least two first flexible tubes 3; a second branch component 4, wherein one end of the second branch component 4 is detachably connected to the first flexible tube 3, and the optical fiber component 7 sequentially passes through the first branch component 2, the first flexible tube 3 and the second branch component 4, and the end of the optical fiber component 7 is connected to a first connector 8.

[0026] In the optical fiber connection device of the present embodiment, the optical fiber 7 in the connection cable 1 is divided into multiple strands by the first branching member 2, and each optical fiber 7 can be extended in the direction of different ends to be connected by bending at a small angle, and each optical fiber is divided into multiple optical fiber 7 by the second branching member 4, and each optical fiber 7 can be bent at a small angle to connect the first connector 8 to the end to be connected of the device. Through the arrangement of the first branching member 2 and the second branching member 4, the optical fiber 7 can be connected to the end to be connected by bending at a small angle twice, thereby making the connection range of the optical fiber 7 wider and the wiring flexibility of the connection cable 1 higher.

[0027] The connecting cable 1 can be regarded as an optical cable. The connecting cable 1 includes a plurality of optical fiber components 7 and a protective layer covering the optical fiber components 7. The optical fiber components 7 can be regarded as optical fibers.

[0028] The first branching member 2 is columnar in shape and is used to divide the optical fiber member 7 in the connecting cable 1 into multiple strands. One end of the first branching member 2 is connected to the connecting cable 1, and the other end of the first branching member 2 is detachably connected to at least two first flexible tubes 3. In this embodiment, the first branching member 2 is connected to two first flexible tubes 3. Depending on the required branches, the first branching member 2 can be connected to different numbers of first flexible tubes 3. The first branching member 2 is in communication with the first flexible tube 3.

[0029] Reference Figure 5 As shown, the first branching member 2 is composed of two detachably connected shells, which can be connected by fasteners, or by snap-fitting. The two shells are arranged to facilitate the assembly of the optical fiber and the first branching member 2. The shell is provided with a receiving groove 21, and at least two wire grooves 22 are provided at the edge of one end of the receiving groove 21, and the optical fiber member 7 passes through the wire groove 22. The shell is also provided with a wire passage 23, which is used for the passage of the optical fiber. The wire passage 23 is connected to the receiving groove 21, and the diameter of the receiving groove 21 is larger than the diameter of the wire passage 22. When the two shells are connected to form the first branching member 2, the two wire passages 22 form a wire hole, and the multiple optical fibers in the connecting cable 1 enter the wire passage 23 and extend from the wire passage 23. The multiple optical fibers form branches when passing through the receiving cavity, that is, the multiple optical fibers are divided into multiple optical fiber members 7 corresponding to the number of wire holes in the receiving cavity, and the multiple optical fiber members 7 respectively pass through a wire hole.

[0030] The first flexible tube 3 is detachably connected to the first branch member 2. The first flexible tube 3 corresponds to the position of the wire hole. Specifically, the first flexible tube 3 can be threadedly connected to the first branch member 2. At least two first flexible tubes 3 are connected to the first branch member 2. Specifically, each optical fiber member 7 passes through a first flexible tube 3. The first flexible tube 3 can be regarded as a flexible armored tube. A reinforcement member is also sleeved on the first flexible tube 3. A sheath is sleeved on the reinforcement member, so that the first flexible tube 3 can be bent and have a certain strength. It can resist corrosion and prevent rodents from damaging the optical fiber member 7, reduce the probability of failure of the optical fiber member 7, enhance the compression and tensile properties of the optical fiber member 7, and make the optical fiber member 7 suitable for different environments. Through the detachable connection between the first flexible tube 3 and the first branch member 2, it can be quickly installed and disassembled, and the cable 1 can be easily connected in a small space, so as to facilitate subsequent maintenance and installation and improve maintenance efficiency.

[0031] One end of the second branch member 4 is detachably connected to the first flexible tube 3, and each second branch member 4 is detachably connected to a single first flexible tube 3. The second branch member 4 has the same structure and function as the first branch member 2, and will not be described in detail. The end of the second branch member 4 is provided with a plurality of through holes, and after the plurality of optical fiber members 7 are divided into a plurality of optical fiber members 7 by the first branch member 2, the plurality of optical fiber members 7 in each optical fiber member 7 are divided into a plurality of separate optical fiber members 7 by the through holes of the second branch member 4, and the end of the optical fiber member 7 is connected to a first connector 8, and the first connector 8 is used to connect to the end to be connected.

[0032] In another embodiment, a third branch component 6 is further included, and the second branch component 4 is also detachably connected to the second flexible tube 5, and the end of the third branch component 6 is detachably connected to the second flexible tube 5. The third branch component 6 has the same structure and function as the first branch component 2, and the second flexible tube 5 has the same structure and function as the first flexible tube 3, which will not be repeated. Each optical fiber component 7 branched from the first branch component 2 is divided into multiple optical fiber components 7 again after passing through the second branch component 4, and each optical fiber component 7 branched from the second branch component 4 is divided into multiple separate optical fiber components 7 after passing through the third branch component 6. Different numbers of branch components can be set according to the number of branches required. The optical fiber component 7 in the connecting cable 1 can pass through the first branch component 2, the first flexible tube 3, the second branch component 4, the second flexible tube 5 and the third branch component 6 in sequence.

[0033] The first branching member 2 is symmetrically connected to the two ends of the connection cable 1, so that the connection cable 1 can connect multiple ends to be connected of multiple devices or distribution frames.

[0034] Reference Figure 3 and Figure 4 As shown, the end of the optical fiber component 7 away from the first connector 8 is connected to the second connector 9. Specifically, the first connector 8 can be regarded as an LC connector. The first connector 8 is suitable for high-density connection, and a spring is provided in the first connector 8 so that the optical fiber is stably connected to the first connector 8. The first connector 8 is used to connect to an external distribution frame. The second connector 9 can be regarded as an FC connector. The second connector 9 is used to connect to the end to be connected of the device. Depending on the needs, different distributors can be connected to the two ends of the optical fiber component 7. Preferably, a third flexible tube is provided between the third branch component 6 and the first connector 8 and the second connector 9. The third flexible tube has the same structure and function as the first flexible tube 3, and will not be repeated. The ends of the first connector 8 and the second connector 9 can be inserted into the third flexible tube, so as to protect the optical fiber component 7, reduce signal loss, and achieve overall protection of the optical fiber component 7 and extend its service life.

[0035] Embodiment 2

[0036] The present invention also provides an optical fiber connection method, which uses the optical fiber connection device in Example 1 to connect equipment, including the following steps: S1: peeling off the protective layer of the connecting cable 1 until the multiple optical fiber components 7 in the connecting cable 1 are exposed; S2: passing the multiple optical fiber components 7 through the first branch component 2, so that the multiple optical fiber components 7 are divided into at least two strands; S3: sleeve a first flexible tube 3 on each optical fiber component 7; S4: passing each optical fiber component 7 through the second branch component 4, so that each optical fiber component 7 is dispersed into multiple optical fiber components 7; S5: the end of each optical fiber component 7 is connected to the first connector 8, and the first connector 8 is connected to the end to be connected.

[0037] In step S1, before stripping the protective layer of the connecting cable 1, the required stripping length is measured. In steps S2 and S4, a protective cover is set on the bending position of the optical fiber component 7 to prevent damage to the bending position of the optical fiber component 7. After completing step S4, waterproof and dustproof sealing materials are coated on both ends of the first branch component 2 and both ends of the second branch component 4, thereby improving the sealing of the first branch component 2, the second branch component 4 and the first flexible tube 3, and also providing the connection strength between the components. In step S1, before stripping the protective layer of the connecting cable 1, the position of the connecting cable 1 is fixed by a fixing ring to prevent the optical fiber component 7 from being loosened or detached from the connector due to force. In step S5, before the optical fiber component 7 is connected to the first connector 8, the end face of the optical fiber component 7 is cut and polished to make the end face of the optical fiber component 7 flat and smooth, thereby reducing the insertion loss, and then the optical fiber component 7 is inserted into the ferrule of the first flexible tube 3, and the optical fiber component 7 and the ferrule are stably fixed by a fixing agent to prevent the optical fiber component 7 from loosening when the first connector 8 is plugged in and out. After the first connector 8 is connected to the optical fiber component 7, the first connector 8 is tested to ensure that the connection quality meets the specification.

[0038] In step S5, after the end of the optical fiber component 7 is connected to the first connector 8, the step of installing a traction net is also included. The traction net is set on the first branch component 2, the first flexible tube 3, the second branch component 4, the optical fiber component 7 and the first connector 8. The traction net is used to firmly bundle the components to avoid pulling the first connector 8 during the wiring process and causing damage to the first connector 8. When the first connector 8 is to be connected to the end to be connected, the traction net is removed.

[0039] An optical fiber connection device and method of the present invention, through the arrangement of a first branch component 2 and a second branch component 4, allows the optical fiber component 7 to be connected to the end to be connected by bending twice at a smaller angle, thereby making the connection range of the optical fiber component 7 wider, and more optical fiber components 7 can be arranged in a limited space, the wiring flexibility of the connecting cable 1 is higher, the density of the optical fiber component 7 is reduced, and the heat dissipation effect is better.

[0040] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
