[0002] The digital optical fiber terminal generally refers to an Optical Network Terminal (ONT for short), which is an important component of a broadband access solution.

Detailed implementation manners

[0024] To better understand the technical content of the present invention, a specific embodiment is provided below, and the present invention will be further described in conjunction with the accompanying drawings.

[0025] See Figures 1 to 5, a digital optical fiber terminal easy to install provided by the present invention includes a terminal main body 1, a detection box body 2, an outer cylinder 3, a main control unit 4 and a plug-in adjustment mechanism. A plurality of optical fiber interfaces 5 are arranged on one side of the terminal main body 1. The outer cylinder 3 is sleeved outside the optical fiber interfaces 5. The detection box body 2 is arranged on the top of the terminal main body 1, and a detection port 6 is arranged on its bottom surface. The detection port 6 is located above the optical fiber interfaces 5. The plug-in adjustment mechanism includes an electric sliding table 7, a top plate 8, a rotary motor 9, a lead screw 10, a sliding seat 11, a first electric push rod 12, an arc plate 13, a second electric push rod 14, a lifting plate 15, a clamping mechanism and an interface loss detection mechanism. The electric sliding table 7 is arranged on the inner top surface of the detection box body 2, and its moving part is connected to the top surface of the top plate 8. The rotary motor 9 is arranged on the bottom surface of the top plate 8, and its output shaft is connected to one end of the lead screw 10. The other end of the lead screw 10 is rotatably connected to the bottom surface of the top plate 8. The top surface of the sliding seat 11 is slidably connected to the bottom surface of the top plate 8, and a through hole 16 is arranged thereon. The first electric push rod 12 is arranged on the inner wall of the through hole 16, and its output shaft is connected to the convex surface of the arc plate 13. Threads (not shown in the figure) are arranged on the concave surface of the arc plate 13. The lead screw 10 passes through the concave surface of the arc plate 13. The second electric push rod 14 is arranged on the bottom surface of the sliding seat 11, and its output shaft is connected to the top surface of the lifting plate 15. The clamping mechanism and the interface loss detection mechanism are respectively arranged on the bottom surfaces of different lifting plates 15. The interface loss detection mechanism includes a plug-in end 17, a detection optical cable 18, an optical pulse generator 19, an optical detector 20, a vertical rod 21 and a sleeve 22. The top end of the vertical rod 21 is connected to the bottom surface of the lifting plate 15, and its bottom end is connected to the top surface of the sleeve 22. The detection optical cable 18 is arranged in the sleeve 22. The plug-in end 17 is connected to one end of the detection optical cable 18. The optical pulse generator 19 and the optical detector 20 are connected to the other end of the detection optical cable 18. An opening 23 is arranged on the top surface of the outer cylinder 3. The opening 23 is located below the moving path of the sleeve 22. The main control unit 4 is arranged on the inner side wall of the detection box body 2 and is respectively connected to the electric sliding table 7, the rotary motor 9, the first electric push rod 12, the second electric push rod 14, the clamping mechanism, the optical pulse generator 19 and the optical detector 20 for data connection.

[0026] For a digital optical fiber terminal easy to install according to the present invention, a plurality of optical fiber interfaces 5 are arranged on one side of the terminal main body 1. An outer cylinder 3 is arranged outside each optical fiber interface 5. The outer cylinder 3 can protect the optical fiber interfaces 5, prevent dust and avoid damage caused by external foreign objects. At the same time, the connecting optical cable can be quickly plugged and installed through the outer cylinder 3, improving the installation efficiency and avoiding wear and damage of the optical fiber interfaces 5 caused by improper installation methods.

[0027] A detection box body 2 is arranged above the terminal body 1. A detection port 6 is arranged on the bottom surface of the detection box body 2 extending above the optical fiber interface 5. An electric sliding table 7 is arranged in the detection box body 2. The electric sliding table 7 can drive the top plate 8 to move, so that the top plate 8 can move above different optical fiber interfaces 5. A rotary motor 9 is arranged on the bottom surface of the top plate 8. The rotary motor 9 can drive the lead screw 10 to rotate. An arc-shaped plate 13 that can move is arranged in the through hole 16 of the sliding seat 11. When the first electric push rod 12 drives the arc-shaped plate 13 to be screwed with the lead screw 10, the rotational movement of the lead screw 10 can be converted into the horizontal movement of the sliding seat 11. When the arc-shaped plate 13 is not screwed with the lead screw 10, the rotational movement of the lead screw 10 will not be converted into the horizontal movement of the sliding seat 11. At this time, the sliding seat 11 will remain suspended on the bottom surface of the top plate 8. The number of sliding seats 11 is two. Second electric push rods 14 are arranged at the bottoms of the two sliding seats 11. The second electric push rods 14 realize the lifting of the clamping mechanism and the interface loss detection mechanism through the lifting plate 15. By controlling the arc-shaped plate 13, the separate movement drive of the clamping mechanism and the interface loss detection mechanism can be realized, so as to realize the independent clamping and interface loss detection. The clamping mechanism can descend to the position of the connecting optical cable and clamp the connecting optical cable. Driven by the lead screw 10, the clamping mechanism can drive the connecting optical cable to move horizontally, so as to realize the disconnection and plug-in installation of the connecting optical cable. An opening 23 is arranged at the top of the outer cylinder 3. The interface loss detection mechanism can descend into the outer cylinder 3 through the opening 23. After being connected to the optical fiber interface 5, the loss of the optical fiber interface 5 is detected. Since the electric sliding table 7 can drive the top plate 8 to move, the interface loss detection mechanism can detect the loss of all optical fiber interfaces 5, so as to obtain the loss of all optical fiber interfaces 5. Thus, the optical fiber interface 5 with less loss can be selected for connection, and automatic connection can be carried out through the clamping mechanism, which is convenient for installation and improves the installation efficiency.

[0028] When detecting the loss of the optical fiber interface 5, the second electric push rod 14 drives the lifting plate 15 to descend, so that the vertical rod 21 drives the sleeve 22 to descend synchronously. Finally, the sleeve 22 will descend into the outer cylinder 3. After the insertion end 17 is aligned with the center of the optical fiber interface 5, the rotary motor 9 drives the sliding seat 11 to move horizontally through the lead screw 10. After the insertion end 17 is connected to the optical fiber interface 5, the optical pulse generator 19 is driven to send an optical pulse to the detection optical cable 18. The optical pulse will return after being transmitted to the optical fiber interface 5 and is received by the optical detector 20. After the optical detector 20 converts the received optical pulse into an electrical signal, the main control unit 4 can perform the loss detection calculation of the optical fiber interface 5, so as to obtain the loss degree of the optical fiber interface 5. Then, the loss of all optical fiber interfaces 5 can be detected, so as to make a choice for the plug-in of the detection optical cable 18.

[0029] Preferably, the plug-in adjustment mechanism further includes a fixing plate 24 and a bearing 25. The fixing plate 24 is arranged on the bottom surface of the top plate 8 and is opposite to the rotary motor 9. The bearing 25 is arranged on the side wall of the fixing plate 24. The end of the lead screw 10 away from the rotary motor 9 is connected to the bearing 25.

[0030] When the rotary motor 9 drives the lead screw 10 to rotate, the end of the lead screw 10 can rotate under the support of the bearing 25 on the side wall of the fixing plate 24, ensuring the stability of rotation.

[0031] Preferably, a T-shaped groove 26 is arranged on the bottom surface of the top plate 8, and a T-shaped block 27 is arranged on the top surface of the sliding seat 11. The T-shaped block 27 is located in the T-shaped groove 26.

[0032] When the sliding seat 11 moves, the T-shaped block 27 at its top can slide along the T-shaped groove 26, preventing the sliding from shifting, ensuring that the clamping mechanism and the interface loss detection mechanism can accurately move to the corresponding positions. When the arc-shaped plate 13 leaves the lead screw 10, the sliding seat 11 will be suspended at the bottom of the top plate 8 under the limitation of the T-shaped block 27 and the T-shaped groove 26.

[0033] Preferably, the clamping mechanism includes a metal plate 28, side plates 29, an electromagnet 30, and a clamping spring 31. The side plates 29 are relatively arranged on the bottom surface of the lifting plate 15. The metal plates 28 are relatively arranged between the side plates 29. The clamping spring 31 connects the metal plate 28 and the side plate 29. The electromagnet 30 is arranged on the side wall of the side plate 29 and is located on one side of the metal plate 28. The main control unit 4 is data-connected to the electromagnet 30. The clamping mechanism further includes a hollow tube 32 and a moving rod 33. The hollow tube 32 is arranged on the side wall of the side plate 29. The clamping spring 31 is arranged in the hollow tube 32. One end of the moving rod 33 is connected to the metal plate 28, and the other end extends into the hollow tube 32 and is connected to the clamping spring 31.

[0034] After the second electric push rod 14 lowers the metal plate 28 to both sides of the connecting optical cable through the lifting plate 15, the current passed through the electromagnet 30 is slowly reduced. The magnetic force received by the metal plate 28 will continuously weaken. Under the action of the clamping spring 31, the metal plate 28 can contact both sides of the cable and realize the clamping and fixing of the cable, facilitating the removal and installation of the connecting optical cable. When the metal plate 28 moves, the moving rod 33 can move along the hollow tube 32, preventing the movement of the metal plate 28 from shifting and ensuring the clamping effect on the connecting optical cable.

[0035] Preferably, the clamping mechanism further includes an airbag 34, an air pump 35, and an air delivery pipe 36. The airbag 34 is disposed on the opposite sidewalls of the metal plate 28. The air pump 35 is disposed on the top surface of the lifting plate 15. The air delivery pipe 36 connects the airbag 34 and the air pump 35. The main control unit 4 is in data connection with the air pump 35. The clamping mechanism further includes an air release pipe 37 and an air valve 38. The air release pipe 37 is connected to the air delivery pipe 36. The air valve 38 is disposed on the air release pipe 37. The main control unit 4 is in data connection with the air valve 38.

[0036] Airbags 34 are provided on both sides of the metal plate 28. After the metal plate 28 contacts the connecting optical cable, the air pump 35 can deliver external air to the airbag 34 through the air delivery pipe 36. After the airbag 34 bulges, it can completely cover the connecting optical cable. Under the action of air pressure, the connecting optical cable can be firmly clamped, so that the disassembly and insertion can be carried out stably. At the same time, the setting of the airbag 34 can be applied to different connecting optical cables. After the disassembly and assembly are completed, the air valve 38 can be opened to discharge the air in the airbag 34 through the air delivery pipe 36 and the air release pipe 37. Then, the current of the electromagnet 30 is increased, and the metal plate 28 is attracted by magnetic force to move, so that the airbag 34 leaves the connecting optical cable, thereby driving the entire clamping mechanism to rise.

[0037] Preferably, the plugging and adjusting mechanism further includes a physical loss detection mechanism. The physical loss detection mechanism includes a biasing spring 39 and a pressure sensor 40. An annular groove 41 is provided on the outer wall of the terminal body 1. The pressure sensor 40 is disposed in the annular groove 41. The end of the outer cylinder 3 extends into the annular groove 41. The biasing spring 39 connects the end of the outer cylinder 3 and the pressure sensor 40. The main control unit 4 is in data connection with the pressure sensor 40.

[0038] In addition to detecting the transmission loss of the optical fiber interface 5, its physical loss is also detected. When the user plugs in the connecting optical cable by himself, there may be a situation of misalignment. At this time, the connecting optical cable will push the entire outer cylinder 3 to move, and the biasing spring 39 will be compressed. At this time, the pressure sensor 40 can detect the pressure provided by the biasing spring 39, which is equivalent to the external force when the user plugs in the connecting optical cable. When the external force is too large, the pressure exerted by the connecting optical cable on the optical fiber interface 5 will also be too large, and the possibility of loss will be greater. Therefore, the main control unit 4 can comprehensively evaluate the loss of the optical fiber interface 5 according to the physical loss and the transmission loss, so as to adjust the plugging position of the connecting optical cable.

[0039] Preferably, the plugging and adjusting mechanism further includes a carrier plate 42. The carrier plate 42 is disposed on the sidewall of the terminal body 1. The bottom surface of the outer cylinder 3 is slidably connected to the top surface of the carrier plate 42. A slider 43 is provided on the top surface of the carrier plate 42. A chute 44 is provided on the bottom surface of the outer cylinder 3. The slider 43 is located in the chute 44.

[0040] In order to ensure that the outer cylinder 3 can successfully protect the optical fiber interface 5, a bearing plate 42 is provided at its bottom to support the outer cylinder 3. When the outer cylinder 3 is pushed by a user when plugging in and connecting an optical cable, the slider 43 will move along the chute 44 to ensure that the movement of the outer cylinder 3 does not deviate, and to ensure the accuracy of the pressure data collected by the pressure sensor 40.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
