Description

Technical Field

[0001] The present invention relates to the technical field of optical cable connection equipment, in particular to an optical cable distribution frame. Background Art

[0002] Fiber optic distribution frames are used to terminate and distribute trunk optical cables at the central office in fiber optic communication systems, facilitating the connection, distribution, and scheduling of optical fiber lines. With the increasing level of network integration, hybrid optical and digital distribution frames integrating ODF, DDF, and power distribution units have emerged. These are suitable for small and medium-sized fiber-to-the-cell, fiber-to-the-building, remote modules, and wireless base stations. Existing fiber optic distribution frames in communication transmission rooms generally include a line-side fiber optic distribution frame and an equipment-side fiber optic distribution frame. External optical cables enter the line-side fiber optic distribution frame and form optical cable terminals in the line-side terminal module of the line-side fiber optic distribution frame. When launching services, fiber jumpers are required from the line-side fiber optic distribution frame to the equipment-side fiber optic distribution frame, forming optical port terminals in the equipment-side terminal module of the equipment-side fiber optic distribution frame.

[0003] Currently, the most common optical cable distribution frames are drawer-type multi-layer distribution frames.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the present invention, when the maintenance personnel perform routine maintenance on the wiring rack, they can first pull out the optical cable from the end of the connector, and then rotate the knob to drive the convex strip on the outside of the cylinder to rotate until it is limited to the groove inside the extrusion block 1 and the extrusion block 2. In this state, the distance between the extrusion block 1 and the extrusion block 2 will increase under the resistance of the convex strip and be larger than the maximum diameter of the cone. At this time, the knob can be used to drive the bending plate 1 to pull the cone and the connecting shaft out of the inside of the connecting plate, so that the limiting effect between the wiring clamp 1 and the connecting plate disappears. At this time, the corresponding wiring clamp 1, wiring clamp 2 and wiring clamp 3 can be rotated out of the shell along the fixed axis by holding the corresponding bending plate 1 or bending plate 2, and the wiring clamp can be continuously rotated out to facilitate the maintenance or repair of the wiring clamp. On the contrary, after the maintenance is completed, the bending plate 1 is reinserted into the interior of the connecting plate using the turning knob. During this process, the elastic force of the torsion spring 1 will reset the convex strip to its original state, and the arc surface area of ​​the cone will resist the inner wall of the gap between the extrusion block 1 and the extrusion block 2. Then, driven by the elastic force of the spring 1 and the spring 2 and the inclined surface resistance, the cone will eventually pass through the extrusion block 1 and then the extrusion block 2, and the restoring elastic force of the spring 1 and the spring 2 will make the extrusion block 1 and the extrusion block 2 close again, and limit the sliding of the cone and the rotation of the bending plate 1. During the entire maintenance process, the staff does not need to use auxiliary tools for installation and disassembly, and can maintain and repair each wire clamp without disassembling the wire clamp, making the overall maintenance process more convenient and quick.

[0016] 2. In the present invention, when the patch panel needs to be maintained on a local wire clamp with the cable inserted, the staff can first pull the auxiliary button on one side of the bending plate 2 in the direction away from the shell, and then the bending rod will drive the limit rod inside the slider to move in the same direction. During the process of the slider shrinking in the outer tube, the end of the slider will gradually resist the end of the cross bar until the ends of the arc surface areas of the two contact each other. The cross bar will pop out to the outside of the shell under the action of the elastic force of the torsion spring 2, and at the same time, the multiple grooves on the surface of the cross bar will contact the original inserted wiring clamp 1 or wiring clamp 1. The cables inside the second wire clamp are summarized and organized so that they expand outward in a fixed direction, reducing the possibility of cable tangle. After that, the staff can pull out the corresponding bending plate 2 by turning the knob to rotate the wire clamp under the cable. The connector inside the wiring clamp 1 will also be slightly rotated in the fan-shaped area along the corresponding direction under the resistance of the cross bar. While ensuring that the optical cable has good expansion space, the resistance of the cross bar to the cable also provides a larger operating space for the staff to wipe the surface of the wire clamp, making the maintenance process more convenient.

One end of the rotating shaft 27 is fixedly connected to the wiring clamp 5, and the rotating shaft 27 is rotatably connected to the connector 23. The connector 23 can rotate freely along the rotating shaft 27 in the sector area 24 under the limiting action of the arc strip 25 and the arc groove 26, thereby increasing the flexibility of the optical cable connection of the wiring clamp, making it easier for the staff to organize and tie the optical cable. The outside of the fixed axis 3 is also provided with a wiring clamp 2 6 and a wiring clamp 3 7. The wiring clamp 5, The outside of the wiring clamp 2 6 and the wiring clamp 3 7 are both provided with a slide bar 8 and fixedly connected thereto, and the inner wall of the housing 1 is provided with a plurality of slide rails 9 for sliding the slide bar 8. The internal structures of the above wiring clamp 1 5, wiring clamp 2 6 and wiring clamp 3 7 are the same, and are all rotatably connected to the fixed shaft 3, so the wiring clamp 1 5 is described as an example. A connecting plate 10 is provided on one side of the housing 1, and one side of the connecting plate 10 is fixedly connected to the housing 1. A bending plate 11 is provided on one side of the connecting plate 10, and one end of the bending plate 11 is fixedly connected to the wiring clamp 1 5;

[0036] Furthermore, a limiting assembly 12 for limiting the rotation of the bending plate 11 is provided inside the connecting plate 10. The limiting assembly 12 includes a connecting shaft 121 that passes through the bending plate 11. A cylinder 122 is provided on the outside of the connecting shaft 121. The cylinder 122 is rotatably connected to the connecting shaft 121. A stopper 123 that resists the bending plate 11 is provided on the outside of the cylinder 122. The stopper 123 is fixedly connected to the cylinder 122. A knob 124 that resists the bending plate 11 is also provided on the outside of the cylinder 122. The knob 124 is fixedly connected to the cylinder 122, one end of the connecting shaft 121 is provided with a connecting column 125, one end of the connecting column 125 is fixedly connected to the connecting shaft 121, one end of the connecting column 125 is provided with a cone 126 and fixedly connected thereto, the outside of the cylinder 122 is provided with an extrusion block 127 and an extrusion block 2 128 for extruding the cylinder 122, one side of the extrusion block 127 is provided with a spring 129, the two ends of the spring 129 are respectively fixedly connected to the extrusion block 127 and the connecting plate 10, A spring 2 1210 is provided on one side of the extrusion block 2 128. The two ends of the spring 2 1210 are fixedly connected to the extrusion block 2 128 and the connecting plate 10 respectively. A convex strip 13 is provided on the outside of the cylinder 122 and is fixedly connected thereto. One end of the convex strip 13 is shaped into an arc surface. The surfaces of the extrusion block 1 127 and the extrusion block 2 128 are provided with a notch 14 for the convex strip 13 to resist. The internal shape of the notch 14 is shaped into an arc surface. The convex strip 13 can enter the interior of the notch 14 and simultaneously connect with the extrusion block 1 127 and the extrusion block 2 12 8 are mutually limited, a torsion spring 15 is provided between the connecting shaft 121 and the cylinder 122, and the two ends of the torsion spring 15 are fixedly connected to the connecting shaft 121 and the cylinder 122 respectively. Under normal conditions, the elastic force of the torsion spring 15 rotates the convex strip 13 on the outside of the cylinder 122 to a state perpendicular to the ground. The elastic force of the torsion spring 15 keeps the convex strip 13 in this state, which is conducive to making the limiting effect of the bending plate 11 in a relatively stable state, and also facilitates the secondary insertion of the bending plate 11 into the interior of the connecting plate 10;

[0037] In addition, an auxiliary rotating assembly 16 for resisting the optical cable is provided on the top of the wiring clamp 2 6. The auxiliary rotating assembly 16 includes a cross bar 161 located between the wiring clamp 2 6 and the wiring clamp 1 5. One end of the cross bar 161 is provided with a fixing ring 162 and is fixedly connected thereto. The fixing ring 162 is located outside the fixed shaft 3. The fixing ring 162 is rotatably connected to the fixed shaft 3. A torsion spring 2 163 is provided between the fixing ring 162 and the fixed shaft 3. The two ends of the torsion spring 2 163 are fixedly connected to the fixing ring 162 and the fixed shaft 3 respectively. Under normal elasticity, the crossbar 161 is rotated to a 45° angle at the outlet of the housing 1. A plurality of grooves 22 for the optical cables to sink into are equidistantly provided on the outside of the crossbar 161. The diameter of the grooves 22 is larger than the diameter of the optical cables. The plurality of grooves 22 are conducive to arranging the optical cables that have been inserted into the wiring clamp 5 when the crossbar 161 is rotated outward, so that the optical cables are pushed outward according to the direction of the inserted state, thereby reducing the possibility of cable entanglement. The inner wall of the housing 1 is provided with a slider 164 for resisting the end of the crossbar 161. The slider 164 is provided with a slider 164 for resisting the end of the crossbar 161. 4 is provided with an outer cylinder 165 on the outside and is slidably connected thereto, and a spring 3 166 is provided inside the outer cylinder 165. The two ends of the spring 3 166 are fixedly connected to the slider 164 and the housing 1 respectively. The end of the cross bar 161 and the end of the slider 164 are both cambered. When the slider 164 contracts toward the inside of the outer cylinder 165, the end cambered area of ​​the cross bar 161 and the cambered area of ​​the slider 164 contact each other, thereby making it easier for the cross bar 161 driven by the elastic force of the hand torsion spring 3 to squeeze the slider 164 and finally rotate outward, A bending plate 2 17 is provided on one side. The connection structure of the wiring clamp 3 7 and the wiring clamp 2 6 are equal, so the following description is based on the wiring clamp 2 6. A limiting rod 18 is provided on one side of the bending plate 2 17 and is inserted into the interior of the slider 164. A bending rod 19 is provided at one end of the limiting rod 18 and is fixedly connected thereto. An auxiliary button 20 is provided at one end of the bending rod 19 and is fixedly connected thereto. A fixing sleeve 21 is provided on the outside of the bending rod 19. The fixing sleeve 21 is located on one side of the bending plate 2 17 and is fixedly connected thereto. The bending rod 19 can slide freely inside the fixing sleeve 21.

[0038] When the cable is disconnected, the cable is disconnected from the cable tray 10 and the cable tray 128 is disconnected. On the contrary, after the maintenance is completed, the bending plate 11 is reinserted into the connecting plate 10 by using the knob 124. During this process, the elastic force of the torsion spring 15 will restore the convex strip 13 to its original state, and the arc surface area of ​​the cone 126 will resist the inner wall of the gap between the extrusion block 127 and the extrusion block 2 128. Then, under the joint drive of the elastic force of the spring 129 and the spring 2 1210 and the inclined surface resistance, the cone 126 will eventually pass through the extrusion block 127 and then the extrusion block 2 128, and the restoring elastic force of the spring 129 and the spring 2 1210 will make the extrusion block 127 and the extrusion block 2 128 close again, and limit the sliding of the cone 126 and the rotation of the bending plate 11. During the entire maintenance process, the staff does not need to use auxiliary tools for installation and disassembly, and can maintain and repair each wire clamp without disassembling the wire clamp, making the overall maintenance process more convenient and quick.

[0039] Secondly, when the patch panel needs to be maintained on a local wire clamp with the cable inserted, the staff can first pull the auxiliary button 20 on the side of the bending plate 17 away from the housing 1, and then the bending rod 19 will drive the limit rod 18 inside the slider 164 to move in the same direction. During the process of the slider 164 shrinking in the outer tube 165, the end of the slider 164 will gradually resist the end of the cross bar 161 until the ends of the arc surface areas of the two contact each other. The cross bar 161 will pop out to the outside of the housing 1 under the action of the elastic force of the torsion spring 163, and at the same time, the multiple grooves 22 on the surface of the cross bar 161 will contact the original plug The cables entering the wiring clamp 1 5 or the wiring clamp 2 6 are summarized and arranged so that they expand outward along a fixed direction, reducing the possibility of cable tangling. After that, the staff can pull out the corresponding bending plate 2 17 through the knob 124 to rotate the wire clamp located under the cable out, and the connector 23 located inside the wiring clamp 1 5 will also be slightly rotated in the fan-shaped area 24 along the corresponding direction under the resistance of the cross bar 161. While ensuring that the optical cable has good expansion space, the resistance of the cross bar 161 to the cable also provides a larger operating space for the staff to wipe the surface of the wire clamp, making the maintenance process more convenient.
