Description

Technical Field

[0001] This utility model relates to the field of fiber optic coupler technology, specifically an adjustable beam angle fiber optic coupler. Background Technology

[0002] Fiber optic couplers are an indispensable component in fiber optic communication systems. Their main function is to enable the efficient transmission of optical signals between optical fibers. In many application scenarios, in order to adapt to different fiber optic connection requirements and improve coupling efficiency, it is necessary to precisely adjust the beam angle. Beam adjustment refers to changing the propagation direction of the beam through physical means to achieve optimal coupling of optical signals between optical fibers. With the rapid development of fiber optic communication technology, the performance requirements for fiber optic couplers are also increasing, especially in situations where the beam angle needs to be dynamically adjusted to adapt to different connection conditions.

[0003] However, when not in use, the openings of traditional fiber optic couplers are easily affected by external dust, leading to dust accumulation during fiber splicing and affecting the coupling efficiency between fibers. In addition, traditional couplers usually use a snap-fit ​​connection method during fiber splicing, which has poor connection stability. If subjected to large external forces, it is easy for the connector and coupler to deviate, causing optical signal loss at the connection point and affecting communication quality. Therefore, an adjustable beam angle fiber optic coupler is needed to solve the existing shortcomings. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an adjustable beam angle fiber coupler. The reset component facilitates the opening of the main body during use, preventing dust accumulation when the main body opening is not in use. The limiting component, through the interlocking of the limiting block and the tooth block, corrects the position of the fiber optic connector, preventing misalignment between the fibers, reducing light loss at the connection point, and ensuring the connection stability of the two fiber optic connectors.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable beam angle fiber coupler, comprising a body and a fiber connector, wherein both ends of the body are provided with sliding grooves, and a reset component is slidably connected to the body through the sliding grooves, and a cover plate is movably connected to the other end of the reset component, the cover plate being adapted to the end opening of the body, the fiber connector being adapted to the opening of the body, a toothed block being fixedly connected to the outside of the fiber connector, the toothed block being adapted to the sliding groove, and a limiting component being provided on the cover plate, and the limiting component being connected to the toothed block.

[0008] The present invention is further configured such that the reset assembly includes a folding spring, a connecting rod, and a support block, one end of the folding spring is fixedly connected to one end of the connecting rod, and the support block is fixedly connected to the other end of the folding spring.

[0014] Beneficial effects:

[0015] Compared with existing technologies, this adjustable beam angle fiber coupler has the following advantages:

[0016] I. This utility model, through the set reset component, facilitates the control of the movement range of the limiting segment. When the support block is at the first end of the limiting segment, the cover plate can block and seal the opening of the main body. When the support block is at the last end of the limiting segment, the cover plate is flush with the side of the main body. At this time, it is convenient to insert the optical fiber connector into the opening of the main body to connect the two optical fibers. It is also beneficial to open the opening of the main body when in use, and to avoid the accumulation of dust in the opening of the main body when not in use.

[0017] II. This utility model, through the setting of a limiting component, rotates the knob, which drives the adjusting column to rotate. One end of the adjusting column pushes the limiting block to move towards the toothed block until the limiting block and the toothed block mesh, causing the return spring to stretch and lengthen. This keeps the fiber optic connector in a fixed position and prevents the fiber optic connector from changing angle. Thus, when the angle of the fiber optic connector changes, the position of the fiber optic connector is corrected by the mutual meshing of the limiting block and the toothed block, preventing misalignment between the fibers, reducing light loss at the connection point, and ensuring the connection stability of the two fiber optic connectors.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-5As shown, this utility model provides a technical solution: an adjustable beam angle fiber coupler, including a body 1 and a fiber connector 2. Both ends of the body 1 are provided with sliding grooves. The body 1 is slidably connected to a reset component 3 through the sliding grooves, and the other end of the reset component 3 is movably connected to a cover plate 4. The cover plate 4 is adapted to the end opening of the body 1. The cover plate 4 is used to seal the opening of the body 1. When the opening of the body 1 is not connected to the fiber connector 2, the cover plate 4 blocks and seals the opening of the body 1 to prevent external dust from entering the interior of the opening of the body 1. This facilitates the normal connection between the optical fibers when the fiber connector 2 is connected, and reduces the influence of dust on the optical fibers. The fiber connector 2 is adapted to the opening of the body 1. A toothed block 5 is fixedly connected to the outside of the fiber connector 2. The toothed block 5 is adapted to the sliding groove. A limiting component 6 is provided on the cover plate 4, and the limiting component 6 is connected to the toothed block 5.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the reset assembly 3 includes a folding spring 301, a connecting rod 302, and a support block 303. One end of the folding spring 301 is fixedly connected to one end of the connecting rod 302, and the support block 303 is fixedly connected to the other end of the folding spring 301. A notch is provided on the cover plate 4. The support block 303 is movably connected to the notch of the cover plate 4 through a rotating shaft. The slide includes a receiving section 7 and a limiting section 8. The receiving section 7 and the limiting section 8 are connected. The folding spring 301 is fixedly connected to the inside of the receiving section 7, and the connecting rod 302 is movably connected to the receiving section 7. The support block 303 is movably connected to the limiting section 8.

[0028] The receiving section 7 provides a space for the folding spring 301 and the connecting rod 302. Through the cooperation of the limiting section 8 and the receiving section 7, the support block 303 can only move in the limiting section 8, which facilitates the control of the movement range of the limiting section 8. When the support block 303 is at the beginning of the limiting section 8, the cover plate 4 can block and seal the opening of the body 1. When the support block 303 is at the end of the limiting section 8, the cover plate 4 is flush with the side of the body 1. At this time, it is convenient to insert the fiber optic connector 2 into the opening of the body 1 to connect the two optical fibers. This is beneficial to open the opening of the body 1 when in use and to prevent dust accumulation in the opening of the body 1 when not in use.

[0029] like Figure 1 and Figure 5As shown, the limiting component 6 includes a limiting block 601, a return spring 602, an adjusting post 603, and a knob 604. One end of the return spring 602 is fixedly connected to the back side of the limiting block 601, and one end of the adjusting post 603 is fixedly connected to one side of the knob 604. The other end of the adjusting post 603 abuts against the back side of the limiting block 601. A receiving groove 9 is provided on the inner side of the cover plate 4. The return spring 602 is fixedly connected inside the receiving groove 9, and the limiting block 601 meshes with the toothed block 5. A thread is provided on the outer side of the adjusting post 603. The adjusting post 603 passes through the cover plate 4 and is threadedly connected to the cover plate 4. The adjusting post 603 is located inside the return spring 602.

[0030] Rotating the knob 604 causes the adjusting column 603 to rotate. One end of the adjusting column 603 pushes the limiting block 601 toward the toothed block 5 until the limiting block 601 engages with the toothed block 5. This causes the return spring 602 to stretch and lengthen, thereby keeping the fiber optic connector 2 in a fixed position and preventing the fiber optic connector 2 from changing angle. Thus, when the angle of the fiber optic connector 2 changes, the position of the fiber optic connector 2 is corrected by the engagement of the limiting block 601 and the toothed block 5, preventing misalignment between the optical fibers, reducing light loss at the connection point, and ensuring the connection stability of the two fiber optic connectors 2.

[0031] like Figure 1 and Figure 3 As shown, a set of symmetrical slots 10 are provided on the main body 1, and a card block 11 is fixedly connected to the fiber optic connector 2. The card block 11 is adapted to the slots 10, which helps to improve the position limitation of the fiber optic connector 2 and avoid the fiber optic connector 2 from shifting due to external force.

[0032] Working principle: In use, pull the cover plate 4 outward to separate it from the opening of the main body 1, causing the connecting rod 302 to move along the receiving section 7, which stretches the folding spring 301. At the same time, rotate the cover plate 4 outward to make it flush with the side of the main body 1. Release the cover plate 4. Under the action of the folding spring 301, the support block 303 moves along the inside of the limiting section 8, and the cover plate 4 moves along the side of the main body 1. Then, insert the fiber optic connector 2 into the opening of the main body 1, insert the locking block 11 into the locking slot 10, and insert the toothed block 5 into the limiting section 8. Next, turn the knob 604 to rotate the adjusting column 603. One end of the adjusting column 603 pushes the limiting block 601 toward the toothed block 5 until the limiting block 601 and the toothed block 5 mesh, which stretches the return spring 602, thereby keeping the fiber optic connector 2 in a fixed position and preventing the fiber optic connector 2 from changing angle. Repeat the same operation to connect another fiber optic connector 2 to the main body 1.

[0033] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
