Description

Technical Field

[0001] This invention relates to the field of fiber optic distribution box technology, and in particular to a non-fusion splicing and non-redundancy fiber optic distribution box and its usage method. Background Technology

[0002] With the rapid development of optical fiber communication technology, optical fiber distribution boxes, as an important component of optical fiber networks, are used for the connection, distribution and management of optical fibers. The optical fibers in existing optical fiber distribution boxes are fixed by fusion splicing, which has poor scalability and is difficult to adapt to the needs of optical fiber networks of different sizes and complexities. In addition, in order to avoid the inability to use the equipment when the optical fiber fails, redundant links need to be set up, resulting in a complex link structure and large size of the distribution box.

[0003] In a fiber optic distribution box with application number CN202510604481.5, the fiber optic connector is fixed in the connector fixing slot, the fiber optic adapter is plugged into the fiber optic connector, the fiber optic adapter is provided with support plates on both sides, the support plates abut against the buffer, and the pigtail connector is plugged into the other end of the fiber optic adapter opposite to the fiber optic connector.

[0004] However, in actual use, fiber optic connectors and pigtails are fixed by fiber optic adapters. After the connector clip is inserted into the clip groove, the locking protrusion and locking groove can prevent the pigtail connector from coming off the pigtail interface. However, the method of fixing the pigtail connector by locking the locking protrusion into the locking groove has the defect of unstable pigtail connector. When the pigtail connector is pulled by external force, it is easy to overcome the locking force of the locking protrusion in the locking groove, causing the pigtail connector to come off, which in turn leads to the failure of the connection between the fiber optic connector and the fiber optic adapter. The anti-disconnection ability is poor.

[0005] Therefore, this invention proposes a fusion-free and redundancy-free fiber optic distribution box and its usage method to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a fusion-free and redundancy-free fiber optic distribution box and its usage method to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a splice-free and redundancy-free fiber optic distribution box, comprising a distribution box and a matching protective cover, wherein multiple sets of linearly arranged fiber optic adapters are provided inside the distribution box, fiber optic connectors are inserted into the fiber optic adapters, a wire winding device for winding the fiber optic connectors is provided inside the distribution box, and a locking device is provided on the fiber optic connectors to lock the fiber optic connectors inside the fiber optic adapters. The fiber optic adapter has a mounting slot, and the mounting slot has a locking slot. The fiber optic connector includes a locking plate housed inside the locking slot. The locking device includes an arc-shaped flexible plate fixed to the outer wall of the locking plate, an arc-shaped piece connected to the bottom end of the arc-shaped flexible plate, a connecting plate connected to the bottom end of the arc-shaped piece, and a sliding plate slidably mounted on the outer side of the fiber optic connector.

[0008] Preferably, the wiring box is evenly provided with partitions, and a wiring chamber is set between two adjacent sets of partitions. A wire support is fixed to the front end of the partition, and a tail stop is integrally connected to the front end of the wiring chamber. A first wire hole is opened on the top of both the wire support and the tail stop. A baffle is integrally formed at the front end of the protective cover. A limiting plate is provided on the inner side of the protective cover and fits against the side wall of the partition. A second wire hole corresponding to the first wire hole is opened on the baffle.

[0009] Preferably, a first optical fiber is fixed in the middle of the rear end of the optical fiber adapter, and buffer springs are provided on both the left and right sides of the rear end of the optical fiber adapter. The other end of the buffer spring is fixed to the inner side wall of the wiring chamber. An optical fiber interface slot is provided inside the optical fiber adapter, and the optical fiber interface slot, the locking slot and the mounting slot are connected.

[0010] Preferably, the fiber optic connector further includes a fiber optic connector fixed to the side wall of the locking plate, and the fiber optic connector matches the fiber optic interface slot. The outer side of the fiber optic connector is wrapped with a protective shell fixed to the locking plate, and a second fiber optic line connected to the fiber optic connector is provided on the protective shell.

[0011] Preferably, the length of the engaging groove is greater than the length of the mounting groove, and the width of the engaging groove is the same as the width of the mounting groove. The width of the engaging plate is the same as the width of the mounting groove, and the length of the mounting groove is greater than the length of the engaging plate.

[0012] Preferably, the wire guide includes a rotating shaft rotatably mounted in the wiring chamber, a coil rod fixed to the top of the rotating shaft, a helical spring sleeved on the outside of the rotating shaft fixed between the bottom of the coil rod and the inner side wall of the wiring chamber, and the second optical fiber wire is wound and assembled on the outer side wall of the coil rod.

[0013] Preferably, the locking device further includes a slide rail formed on the outer wall of the protective housing, a slider is slidably mounted in the slide rail, the slider is fixed on the slide plate, a support spring is fixed on the side wall of the slider away from the fiber optic adapter, and the other end of the support spring is fixed on the inner wall of the slide rail.

[0014] Preferably, the engaging groove and the mounting groove are connected by an arc-shaped surface, and the arc-shaped piece and the arc-shaped surface are in contact.

[0015] Preferably, the arc-shaped flexible plate includes a pressure-bearing part fixed to the outer wall of the locking plate, and the pressure-bearing part is housed inside the locking groove. The bottom end of the pressure-bearing part is integrally formed with a locking part, which abuts against the inner wall of the locking groove. The locking part is connected to the arc-shaped piece, and the end of the locking part is directly opposite the bottom of the locking plate.

[0016] This invention provides a method for using a fusion-free and redundancy-free fiber optic distribution box. The steps of the method are as follows: S1: Multiple fiber optic adapters are evenly distributed inside the patch panel to facilitate fiber optic organization, while fiber optic connectors are stored in the wiring compartment and plugged into the fiber optic adapters. S2: The cable guide winds the second fiber optic cable on the fiber optic connector to ensure it is neatly stored in the wiring chamber, preventing excessive bending and damage. S3: When the fiber optic connector is installed inside the fiber optic adapter, the arc-shaped flexible plate on the locking device is housed in the locking groove. The locking plate is supported and limited by the cooperation of the pressure bearing part and the locking part. When the fiber optic connector is detached outward, the locking part is deformed due to compression and abuts against the bottom of the locking plate to limit the locking plate, thereby completing the self-locking of the fiber optic connector. It has strong stability and prevents the fiber optic connector from detaching from the fiber optic adapter due to external pulling. S4: When removing the fiber optic connector from the fiber optic adapter, manually slide the sliding plate. The sliding plate will pull the connecting plate to pull the arc-shaped piece, thereby causing the arc-shaped piece to deform the locking part and move along the arc surface. At the same time, the pressure bearing part will deform synchronously and fit against the locking plate. That is, the external force will cause the arc-shaped flexible plate and the arc-shaped piece to disengage from the locking groove, thereby releasing the locking plate from its limit in the locking groove. Then pull the fiber optic connector outward to remove the fiber optic connector from the fiber optic adapter. The operation is convenient.

[0017] The technical effects and advantages of this invention are as follows: The fiber optic connector of this invention is simple and convenient to disassemble. External force releases the limiting mechanism within the locking slot, ensuring smooth disassembly. By incorporating a locking device on the fiber optic connector, the self-locking mechanism and disassembly method are improved. The locking device enhances the stability and tensile strength between the fiber optic connector and the fiber optic adapter, effectively solving the problem of fiber optic connector detachment caused by loose or unstable engagement between the locking protrusion and locking slot in traditional technologies. Simultaneously, the design of the fiber optic cable holder ensures orderly and safe storage of the optical fibers on the connector, preventing excessive bending and damage, and extending the lifespan of the fiber optic connector. The fiber optic distribution box has a reasonable design structure, improving the fixing stability of the fiber optic connector, overcoming the shortcomings of existing technologies, and exhibiting better tensile and impact resistance, making it more reliable in use.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 10As shown, this embodiment discloses a splice-free and redundancy-free fiber optic distribution box, including a distribution box 10 and a matching protective cover 50. The distribution box 10 contains multiple linearly arranged fiber optic adapters 20, each with a fiber optic connector 30 inserted into it. The distribution box 10 also contains a wire guide 40 for winding the fiber optic connectors 30. Each fiber optic connector 30 is equipped with a locking device 60 that self-locks the connector inside the fiber optic adapter 20. The fiber optic adapters 20 are arranged linearly inside the distribution box 10 and can be inserted into the fiber optic connectors 30, forming a pluggable connection structure. Each fiber optic adapter 20 contains a fiber optic connector 30. The distribution box 10 also contains a wire guide 40 specifically for winding the fiber optic cable onto the connector 30, ensuring that the fiber optic connectors 30 can be stored orderly and safely. The locking device 60 improves the stability of the fiber optic connector 30 inside the fiber optic adapter 20, achieving self-locking.

[0022] Please see Figure 7 and Figure 8 The fiber optic adapter 20 has a mounting slot 21, and a locking slot 22 is provided inside the mounting slot 21. The fiber optic connector 30 includes a locking plate 31 housed inside the locking slot 22.

[0023] Please see Figure 8 The locking device 60 includes an arc-shaped flexible plate 61 fixed to the outer wall of the locking plate 31. An arc-shaped piece 62 is connected to the bottom end of the arc-shaped flexible plate 61, and a connecting plate 63 is connected to the bottom end of the arc-shaped piece 62. A sliding plate 64 is slidably mounted on the outer side of the fiber optic connector 30. When the fiber optic connector 30 is pulled outward, the arc-shaped flexible plate 61 will deform due to the action of external force, thereby releasing the fit with the inner wall of the locking groove 22 and ensuring that the fiber optic connector 30 can be smoothly pulled out.

[0024] Please see Figure 2 and Figure 3 The wiring box 10 is evenly equipped with partitions 11. A wiring chamber 12 is set between two adjacent sets of partitions 11. A cable support 13 is fixed to the front end of the partition 11. A tail stop 14 is integrally connected to the front end of the wiring chamber 12. The top of the cable support 13 and the tail stop 14 are both provided with a first wire hole 15. The independent wiring chamber 12 can improve the orderliness and maintenance convenience when connecting optical fibers. The first wire hole 15 on the tail stop 14 and the cable support 13 can store and limit the optical fiber.

[0025] Please see Figure 1 and Figure 2The protective cover 50 has a baffle 51 integrally formed at the front end, and a limiting plate 53 that fits against the side wall of the partition 11 is provided on the inner side of the protective cover 50. The baffle 51 has a second wire hole 52 that corresponds to the first wire hole 15. The protective cover 50 is fastened to the wiring chamber 12, and the limiting plate 53 can fit tightly against the partition 11. It can position the protective cover 50 when it is placed on the top of the wiring box 10, ensuring that the protective cover 50 can accurately correspond to the wiring chamber 12 and complete the protective coverage of the wiring chamber 12.

[0026] Please see Figure 6 The fiber optic adapter 20 has a first fiber optic cable 25 fixed in the middle of its rear end. Buffer springs 26 are provided on both the left and right sides of the rear end of the fiber optic adapter 20. The other end of the buffer spring 26 is fixed to the inner wall of the wiring chamber 12, which further improves the impact resistance and stability of the fiber optic adapter 20. The two ends of the buffer spring 26 are fixed between the two sides of the fiber optic adapter 20 and the inner wall of the wiring chamber 12, which can effectively reduce the impact force when the fiber optic connector 30 is inserted and pulled out, and avoid excessive pulling force that could damage or cause the fiber optic connector 30 to fall off.

[0027] Please see Figure 7 The fiber optic adapter 20 has a fiber optic interface slot 23, and the fiber optic interface slot 23, the locking slot 22 and the mounting slot 21 are connected. The length of the locking slot 22 is greater than the length of the mounting slot 21, and the width of the locking slot 22 is the same as the width of the mounting slot 21. The width of the locking plate 31 is the same as the width of the mounting slot 21, and the length of the mounting slot 21 is greater than the length of the locking plate 31, so that the locking plate 31 can be retracted from the mounting slot 21 into the locking slot 22. The size design of the locking slot 22 matches the locking plate 31 on the fiber optic connector 30.

[0028] Please see Figure 8 The fiber optic connector 30 also includes a fiber optic connector 32 fixed to the side wall of the locking plate 31, and the fiber optic connector 32 and the fiber optic interface slot 23 are matched. The outer side of the fiber optic connector 32 is wrapped with a protective shell 33 fixed to the locking plate 31. A second fiber optic line 34 connected to the fiber optic connector 32 is provided on the protective shell 33. The fiber optic connector 32 is connected in the fiber optic interface slot 23.

[0029] Please see Figure 8The fiber optic cable connector 40 includes a rotating shaft 41 rotatably mounted in the wiring chamber 12. A coil rod 42 is fixed to the top of the rotating shaft 41. A spiral spring 43 sleeved on the outside of the rotating shaft 41 is fixed between the bottom of the coil rod 42 and the inner wall of the wiring chamber 12. The second optical fiber 34 is wound and assembled on the outer wall of the coil rod 42 to neatly wind the second optical fiber 34 on the optical fiber connector 30, avoiding excessive bending and damage to the optical fiber 34. Through the cooperation of the rotating shaft 41 and the coil rod 42, the fiber optic cable connector 40 can orderly store the optical fiber 34 in the wiring chamber 12, improving the overall stability and service life of the optical fiber connector 30. Moreover, the second optical fiber 34 can be stored in the first wire hole 15 and the second wire hole 52, realizing the limiting clamping of the second optical fiber 34.

[0030] Please see Figures 8-10 The locking device 60 also includes a slide 65 formed on the outer wall of the protective shell 33. A slider 66 is slidably mounted in the slide 65. The slider 66 is fixed on the slide plate 64. A support spring 67 is fixed on the side wall of the slider 66 away from the fiber optic adapter 20. The other end of the support spring 67 is fixed on the inner wall of the slide 65. The engaging groove 22 and the mounting groove 21 are connected by an arc-shaped surface 24. The arc-shaped piece 62 and the arc-shaped surface 24 are in contact. The arc-shaped flexible plate 61 includes a pressure-bearing part 611 fixed on the outer wall of the engaging plate 31. The pressure-bearing part 611 is housed inside the engaging groove 22. A locking part 612 is integrally formed at the bottom end of the pressure-bearing part 611. The locking part 612 abuts against the inner wall of the engaging groove 22. The locking part 612 is connected to the arc-shaped piece 62. The end of the locking part 612 is directly opposite the bottom of the engaging plate 31.

[0031] In practical use, to enhance tensile strength, the self-locking structure of the fiber optic connector 30 also achieves higher fixing strength through the cooperation of the pressure-bearing part 611 and the locking part 612 of the arc-shaped flexible plate 61. The pressure-bearing part 611 is located inside the locking groove 22 and limits the installation position of the fiber optic connector 30 by cooperating with the locking plate 31. The locking part 612 enhances the fixing stability of the fiber optic connector 30 by abutting against the inner wall of the locking groove 22, effectively preventing the fiber optic connector 30 from detaching when pulled by external force. This solves the connection failure problem caused by unstable locking or poor fit between the locking protrusion and the locking groove in the traditional technology. Moreover, the support spring 67 can provide support force to the slider 66 and the sliding plate 64, thereby preventing the sliding plate 64 from slipping and providing support strength for the locking of the arc-shaped flexible plate 61 inside the locking groove 22.

[0032] This embodiment discloses a method for using a fusion-free and redundancy-free fiber optic distribution box. The steps of the method are as follows: S1: Multiple fiber optic adapters 20 are evenly distributed inside the patch panel 10 to facilitate fiber optic routing, while the fiber optic connectors 30 are stored in the wiring compartment 12 and plugged into the fiber optic adapters 20. S2: The wire guide 40 winds the second optical fiber 34 on the optical fiber connector 30 to ensure that it is neatly stored in the wiring chamber 12 and to avoid excessive bending and damage. S3: When the fiber optic connector 30 is installed inside the fiber optic adapter 20, the arc-shaped flexible plate 61 on the locking device 60 is housed in the locking groove 22. The locking plate 31 is supported and limited by the cooperation of the pressure bearing part 611 and the locking part 612. When the fiber optic connector 30 is disengaged outward, the locking part 612 is deformed due to compression and abuts against the bottom of the locking plate 31 to limit the locking plate 31, thereby completing the self-locking of the fiber optic connector 30. It has strong stability and avoids the fiber optic connector 30 from disengaging from the fiber optic adapter 20 due to external pulling. S4: When pulling the fiber optic connector 30 out of the fiber optic adapter 20, manually slide the sliding plate 64. The sliding plate 64 drives the connecting plate 63 to pull the arc-shaped piece 62, thereby causing the arc-shaped piece 62 to pull the locking part 612 to deform and then move along the arc-shaped surface 24. At the same time, it pulls the pressure bearing part 611 to deform synchronously and fit onto the locking plate 31. That is, the external force causes the arc-shaped flexible plate 61 and the arc-shaped piece 62 to separate from the locking groove 22, thereby releasing the locking plate 31 from the locking groove 22. Then pull the fiber optic connector 30 outward to pull the fiber optic connector 30 out of the fiber optic adapter 20. The operation is convenient.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
