Description

Technical Field

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

[0002] Fiber optic splitter boxes are wiring and distribution equipment for user terminals in FTTH systems. They are typically used outdoors, in corridors, or indoors to connect trunk optical cables with distribution cables. They can perform functions such as fiber splicing, distribution, and scheduling. Existing fiber optic splitter boxes typically have multiple interfaces to accommodate the simultaneous connection of multiple optical fibers. Common examples include 12-core and 24-core fiber optic splitter boxes.

[0003] The multiple interfaces of a conventional multi-core fiber optic distribution box are arrayed on the side wall of the box. A fiber optic flange is installed in the interface to connect the connector outside the box and the adapter inside the box. The two ends of the fiber optic flange are constructed as threads or snaps. When the connector outside the box is inserted, the threaded connection needs to be aligned with the flange at the interface and inserted and rotated. The snap connection requires manual pressing of the connector to insert the connector into the flange and then fasten it. However, whether it is a threaded connection or a snap connection, manual operation is required at the interface, and manual tightening or plugging requires a certain amount of operating space to be reserved. Therefore, when multiple interfaces are arrayed on the side wall of the box, sufficient operating space needs to be reserved between each interface. However, when there are multiple interfaces, such as a 48-core fiber optic distribution box, the space between each interface is limited if the box size remains unchanged, and there may be a situation where there is insufficient operating space and it is inconvenient to insert the connector. Summary of the Invention

[0004] In order to solve the problem of insufficient operating space for inserting connectors into an optical fiber distribution box with multiple interfaces, the present application provides an optical fiber flange structure.

[0005] The optical fiber flange structure provided in this application adopts the following technical solution:

[0006] An optical fiber flange structure, comprising:

[0007] A fixed base, wherein the fixed base has a docking channel therein, and the docking channel is for inserting the optical fiber connector;

[0008] A column, the column being slidably connected to the fixed base, the column being located on at least one side of the docking channel; the column being provided with a fixed protrusion on the side facing the docking channel, the column being slidable along its length so that the fixed protrusion is disengaged or irreversibly extended into the docking channel;

[0009] A reset member is located on the fixed base and forces the column to slide in one direction so that the fixed protrusion always has a tendency to reset into the docking channel.

[0010] By adopting the above technical solution, the reset member is driven to force the column to slide in one direction, causing the fixed protrusion to disengage from the docking channel. At this time, the reset member has a tendency to reset. The optical fiber connector is then inserted into the docking channel to connect it in place. The driving force of the reset member is then removed. The elastic force generated by the reset member to reset drives the column to slide in the opposite direction. At this time, the fixed protrusion will extend into the docking channel irreversibly, thereby locking the optical fiber connector located in the docking channel. The connection and locking of the optical fiber connector only requires the operation of driving the reset member to slide the column and removing the driving force to reset the column. Specifically, during operation, the locking is completed by manually pressing, inserting the connector, and then releasing it. There is no need to manually tighten the connector or grasp the connector by hand to tighten it, and the required operating space is small.

[0011] Preferably, the fixed base has a slide groove, the slide groove is connected to the docking channel, and the column slides in the slide groove along the length direction of the column.

[0012] Preferably, the column has a limiting protrusion on the side away from the docking channel, and the fixed base has a limiting groove for the limiting protrusion to slide, the limiting groove is connected to the sliding groove, and the limiting protrusion only slides in the limiting groove, and the reset member always has a reset tendency so that the limiting protrusion abuts against the groove wall at one end of the limiting groove after sliding.

[0013] Preferably, a clearance space communicating with the slide groove and the docking channel is provided on the fixed base, and the fixed protrusion moves into the clearance space after being separated from the docking channel.

[0014] Preferably, a pressing plate is connected to the column, one end of the reset member abuts against the pressing plate, and the other end of the reset member abuts against the fixed base.

[0015] Preferably, a sleeve is passed through the fixed base, the reset member is sleeved on the sleeve, one end of the sleeve is connected to the pressing plate, and the other end of the sleeve is passed through the fixed base, and the sleeve can slide along its axial direction.

[0016] Preferably, a guide buckle is provided on the fixing base and on the inner wall of the docking channel, and the guide buckle is used to clamp the optical fiber connector and to indicate that the optical fiber connector is connected in place.

[0017] Preferably, an optical cable fiber distribution box comprises a box body and a box cover, wherein the box body has the optical fiber flange structure as described above, wherein the box cover has a pressing hole, and the pressing plate is pressed through the pressing hole.

[0018] Preferably, a button is provided on the pressing plate, the button abuts against the pressing plate, and the button extends from the pressing hole.

[0019] Preferably, the button is provided with a limiting ring, which presses against the inner wall of the box cover to prevent the button from falling out.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] Save operating space. The optical fiber connector can be fixed by pressing the pressing plate or button with your fingers. There is no need to tighten it manually or grasp it with your hands. The required operating space is small, and more interfaces can be set up when the size of the optical cable distribution box remains unchanged.

[0022] Easy to operate and well guided, just press or release the button to switch the locking state. In the case of blind insertion of the optical fiber connector, the guide buckle can be tightened to indicate that the optical fiber connector is connected in place, and then the button can be operated to lock the connector;

[0023] The locking effect is good. Different from locking the optical fiber connector by the elastic force of the elastic member, the locking component of the present application is a rigid component, that is, the connector is locked by the column and the protrusion, and it is difficult to lose the locking performance due to overcoming the elastic force of the elastic member.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-11 This application is described in further detail.

[0037] The embodiment of the present application discloses a fiber optic flange structure. The fiber optic flange is used to connect two optical paths. One end of the fiber optic flange is for the fiber optic connector 3 to be inserted and connected. The other end of the fiber optic flange can be constructed to connect to the fiber optic connector 3 or to be directly led out of the optical cable, thereby achieving a quick connection between optical paths through the fiber optic flange structure. Figure 1 and Figure 2 The optical fiber flange structure includes a fixed base 1 and a pressing fixture 2. The fixed base 1 is used to insert the optical fiber connector 3. The pressing fixture 2 is provided on the fixed base 1 to lock the optical fiber connector 3. The pressing fixture 2 includes a column 21, a pressing block 22 and a reset member 23. The column 21 is passed through the fixed base 1 and can slide along the length direction of the column 21. The column 21 is used to clamp the optical fiber connector 3. The pressing block 22 is connected to the column 21. One end of the reset member 23 abuts the pressing block 22, and the other end abuts the fixed base 1. Pressing the pressing block 22 forces the column 21 to slide. At this time, the optical fiber flange is in an unlocked state. After inserting the optical fiber connector 3, release the pressing block 22. The reset member 23 resets and causes the column 21 to slide in the opposite direction, thereby switching to a locked state and clamping the optical fiber connector 3 on the optical fiber flange structure.

[0038] Reference Figure 3 and Figure 4 The fixed base 1 has a docking channel 11 for inserting the optical fiber connector 3. The docking channel 11 is divided into a circular channel 111 and a square channel 112 along the axial direction. When the optical fiber connector 3 is inserted, it first enters the circular channel 111 and then enters the square channel 112. The square channel 112 can prevent the optical fiber connector 3 from rotating in the circumferential direction. The column 21 is located on at least one side of the docking channel 11. A preferred embodiment is to have a column 21 on each side of the docking channel 11. The fixed base 1 has a slide groove 12 on both sides of the docking channel 11 for the column 21 to slide. The slide groove 12 is connected to the docking channel 11. The column 21 can slide in the slide groove 12 along the length of the column 21.

[0039] Reference Figure 1 and Figure 4 The side of the column 21 facing the docking channel 11 has a fixing protrusion 211, which is used to clamp the optical fiber connector 3 in the docking channel 11. The fixing protrusion 211 can be a convex hemisphere. A preferred embodiment is that each column 21 on both sides has one. The outer circumference of the optical fiber connector 3 has an annular groove 31 for the fixing protrusion 211 to engage. The two fixing protrusions 211 are stuck in the annular groove 31, limiting the axial slippage of the optical fiber connector 3, thereby clamping and fixing the optical fiber connector 3 to the optical fiber flange. When the column 21 is located on one side of the docking channel 11, the corresponding sliding groove 12 for the sliding of the column 21 is provided on one side, and a fixing protrusion 211 is provided on the column 21. One fixing protrusion 211 is stuck in the annular groove 31 of the optical fiber connector 3, which can also limit the axial slippage of the optical fiber connector 3.

[0040] Reference Figure 4 and Figure 5 The fixed base 1 has a clearance space 13 for temporarily accommodating the fixing protrusion 211. The clearance space 13 is connected to the slide groove 12 and the docking channel 11 and can be located at one end of the slide groove 12. When the optical fiber connector 3 needs to be inserted, the driving column 21 moves the fixing protrusion 211 to the clearance space 13, reserving space for the insertion of the optical fiber connector 3. After the optical fiber connector 3 is inserted, the fixing protrusion 211 is reset to lock the optical fiber connector 3.

[0041] One end of the two side columns 21 is connected to a pressing plate 221, and the pressing plate 221 is used to drive the columns 21 to make the two side columns 21 slide synchronously, so that the fixed protrusion 211 disengages from the docking channel 11 or extends into the docking channel 11 irreversibly. The fixed protrusion 211 disengages from the docking channel 11 and is in an unlocked state, and the fixed protrusion 211 irreversibly extends into the docking channel 11 and is in a locked state. There is a limiting protrusion 212 on the column 21, and one limiting protrusion 212 is provided on each of the two side columns 21. The limiting protrusion 212 is used to limit the column 21 to remain relatively fixed in the locked state, so that the fixed protrusion 211 is always located in the docking channel 11. There is a limiting groove 14 for the limiting protrusion 212 to slide on the fixed base 1. The limiting protrusion 212 can only slide in the limiting groove 14. When the limiting protrusion 212 slides to the limiting groove 14, one end abuts against the groove wall of the limiting groove 14, thereby keeping the column 21 relatively fixed. Figure 5 For example, the limiting groove 14 is connected with the slide groove 12, one end of the slide groove 12 has an opening, and one end of the limiting groove 14 has a groove wall for the limiting protrusion 212 to abut against, and the clearance space 13 is close to the other end of the slide groove 12 and is connected with the slide groove 12 and the limiting groove 14. The clearance space 13 is located at the lower left corner and the lower right corner of the docking channel 11, which can make the fixing protrusion 211 out of the range of the axial projection of the docking channel 11.

[0042] Reference Figure 6 The column 21 is installed through the opening at one end of the chute 12. The opening of the chute 12 must be larger than the cross-section of the column 21 so that the fixing protrusion 211 and the limiting protrusion 212 can pass through the opening of the chute 12. When the column 21 is installed into the chute 12, the fixing protrusion 211 first passes through the opening of the chute 12, and then the limiting protrusion 212 passes through the opening of the chute 12. The limiting protrusion 212 is then moved into the limiting groove 14 and abuts against the groove wall of the limiting groove 14. The column 21, the fixing protrusion 211, and the limiting protrusion 212 can be made of rigid materials and are not easily deformed.

[0043] Reference Figure 4 and Figure 5 The reset member 23 is located on the fixed base 1. In one embodiment, the reset member 23 is a spring, located between the two side columns 21 and on one side of the docking channel 11, and is arranged parallel to the column 21. One end of the reset member 23 abuts the pressing plate 221, and the other end of the reset member 23 abuts the fixed base 1. Figure 4As shown, in the initial state, the reset member 23 is in a compressed state. The resilience of the reset member 23 to reset presses against the pressing plate 221, and causes the limiting protrusion 212 to press against the upper wall of the limiting groove 14, so that the fixed protrusion 211 is relatively fixed in the docking channel 11. When it is necessary to switch to the unlocked state, the pressing plate 221 is pressed downward, causing the column 21 to slide axially downward, and the fixed protrusion 211 gradually disengages from the docking channel 11 and moves to the clearance space 13 to rest. At this time, the reset member 23 is further compressed downward, releasing the pressure on the pressing plate 221. The resilience of the reset member 23 causes the pressing plate 221 and the column 21 to reset upward, and the limiting protrusion 212 presses against the upper wall of the limiting groove 14. At this time, the fixed protrusion 211 is irreversibly extended into the docking channel 11. In addition, the "up" and "down" referred to above are based on the directions of the accompanying drawings.

[0044] Reference Figure 7 Obviously, the reset member 23 can also be located on the other side of the docking channel 11 between the two side columns 21. In this case, both ends of the column 21 are connected to a pressing plate 221, and the pressing plates 221 at both ends of the column 21 are respectively a first pressing plate 222 and a second pressing plate 223. The reset member 23 is located on the side of the second pressing plate 223 facing away from the docking channel 11. One end of the reset member 23 abuts the fixed base 1, and the other end of the reset member 23 abuts the second pressing plate 223. Similarly, in the initial state, the reset member 23 is in a compressed state. The rebound force of the reset member 23 causes the limiting protrusion 212 to press against the groove wall of the limiting groove 14, and the fixing protrusion 211 is relatively fixed in the docking channel 11. When switching to the unlocked state, pressing the first pressure plate 222 drives the column 21 to slide, and the column 21 synchronously drives the second pressure plate 223 to further compress the reset member 23, and the fixed protrusion 211 gradually withdraws from the docking channel 11 and moves to the clearance space 13 to stay. The pressure on the first pressure plate 222 is released, and the rebound force of the reset member 23 to reset causes the column 21 to slide, and the limiting protrusion 212 presses against the groove wall of the limiting groove 14, and the fixed protrusion 211 is irreversibly reset to the docking channel 11.

[0045] Reference Figure 4 and Figure 6The fixed base 1 has a guide hole 15, through which a sleeve 224 is inserted. The sleeve 224 can slide axially within the guide hole 15. One end of the sleeve 224 abuts the pressing plate 221, while the other end of the sleeve 224 penetrates the guide hole 15 and extends into the fixed base 1. A reset member 23 is sleeved on the sleeve 224. One end of the reset member 23 abuts the pressing plate 221, while the other end abuts the outer surface of the fixed base 1 on one side of the guide hole 15. The sleeve 224 is arranged parallel to the column 21 to serve as a guide. The sleeve 224 restricts the column 21 from sliding axially along its length, limiting the column 21 from shaking in other directions. Pressing the pressing plate 221 causes the pressing plate 221 to slide against the sleeve 224. The sleeve 224 then slides axially into the fixed base 1 in the pressing direction, squeezing the reset member 23 against the pressing plate 221.

[0046] Reference Figure 1 and Figure 8 In a preferred embodiment, the pressing block 22, the column 21, the reset member 23 and the sleeve 224 are arranged perpendicular to the fixed base 1. In addition, the pressing block 22, the column 21, the reset member 23 and the sleeve 224 can also be arranged tilted, and the tilt direction is as shown in the attached figure. Figure 8 In the direction indicated by the middle arrow, accordingly, the sliding groove 12 and the limiting groove 14 also adjust the angle to adapt to the oblique sliding of the column 21. Therefore, whether it is set vertically or tilted, the optical fiber connector 3 can be clamped.

[0047] Reference Figure 1 and Figure 6 The inner wall of the square channel 112 on the fixed base 1 has guide clips 16. The guide clips 16 can be arranged on both sides of the inner wall of the fixed base 1 and are inclined toward the inside of the docking channel 11. When the optical fiber connector 3 is inserted, the guide clips 16 cooperate with the corresponding slots 32 on the optical fiber connector 3 to achieve the connection of the optical fiber connector 3. At the same time, the guide clips 16 can indicate that the optical fiber connector 3 is in place, thereby further locking the optical fiber connector 3.

[0048] Reference Figure 1 and Figure 9 In addition, when the optical fiber connector 3 does not need to be inserted, the dust cap 4 can be inserted to block the docking channel 11 to prevent water and dust from entering. Similarly, the dust cap 4 is locked and fixed by driving the column 21 through the pressing plate 221 and the reset member 23.

[0049] The implementation principle of the optical fiber flange structure of the embodiment of the present application is as follows: when inserting the optical fiber connector 3, pressing the pressing plate 221 drives the sleeve 224 and the column 21 to slide axially along the pressing direction, the reset member 23 is further compressed, and the fixing protrusion 211 gradually withdraws from the docking channel 11 and moves to the clearance space 13 to stay, and the optical fiber connector 3 is inserted into the docking channel 11 along the guide buckle 16. The guide buckle 16 and the optical fiber connector 3 are completely engaged, indicating that the optical fiber connector 3 is connected in place. At this time, the pressure on the pressing plate 221 is released, and the rebound force of the reset member 23 to be reset abuts against the pressing plate 221, causing the column 21 to gradually slide and reset until the limiting protrusion 212 abuts against the groove wall of the limiting groove 14. At the same time, the fixing protrusion 211 gradually moves out of the clearance space 13 and extends into the docking channel 11 without retreat, gradually clamping the optical fiber connector 3 in the docking channel 11.

[0050] The present application also discloses an optical fiber distribution box, referring to Figure 10 and Figure 11, which includes the above-mentioned optical fiber flange structure and a box body 5 and a box cover 6, wherein the box body 5 and the box cover 6 are hingedly connected. The optical fiber flange structure includes a fixed base 1 and a pressing fixture 2, and the fixed base 1 has a docking channel 11 for inserting the optical fiber connector 3. The fixed base 1 is fixed on the base of the box body 5, and the docking channel 11 runs through the side wall of the box body 5. The pressing fixture 2 includes a pressing block 22, a reset member 23 and a column 21. The pressing block 22 includes a pressing plate 221, and the pressing plate 221 is used to drive the reset member 23 and the column 21 to switch the state of the optical fiber flange, and the column 21 is used to clamp the optical fiber connector 3. By pressing the pressing plate 221, the reset member 23 is compressed, and the column 21 slides axially to switch the optical fiber flange to the unlocked state. After the optical fiber connector 3 is inserted, the pressing plate 221 is released, and the elastic force of the reset member 23 resets the column 21 to switch to the locked state. The box cover 6 is provided with a pressing hole 61, through which the pressing plate 221 can be pressed when the box cover 6 is closed. The pressing block 22 also includes a button 225, which is provided on the pressing plate 221. The button 225 penetrates the pressing hole 61 and is flush with the box cover 6. The pressing plate 221 can be pressed by pressing the button 225 from outside the box body 5. The button 225 is connected to a fixing post 226. The pressing plate 221 has a fixing groove 227 above. The fixing post 226 is locked in the fixing groove 227 to connect the button 225 to the pressing plate 221. The fixing post 226 is located in the center of the pressing plate 221, which ensures that the force applied to the pressing plate 221 is relatively uniform when pressed, thereby causing the two side columns 21 to slide synchronously. The button 225 abuts against the inner wall of the box cover 6 to prevent it from falling out of the box body 5. Specifically, a limiting ring 228 can be provided around the circumference of the button 225. The outer circumference of the button 225 is stepped. The limiting ring 228 abuts against the inner wall of the box cover 6 to prevent the button 225 from falling out of the pressing hole 61. Furthermore, a sealing ring 7 is provided on the button 225 to seal the pressing hole 61 and prevent water and dust from entering the box body 5.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
