Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber connectors, and particularly to a fast optical fiber connector. Background Art

[0002] An optical fiber connector is an optical device used at the end of an optical cable. By precisely aligning the cores of two optical fibers, low-loss and highly reliable transmission of optical signals is achieved. The optical fiber connector is usually inserted into the interface of an optical module to transmit optical signals from devices such as switches and routers to the optical fiber link. For 40G / 100G networks, MPO multi-core connectors are required. Dozens of ports can be integrated on a single panel to meet the centralized cabling of TOR switches. For example, FTTH splitters require multiple SC / LC interfaces to support connecting the user side and the central office optical cables on the same panel.

[0003] Because the gap between connectors is too small, it is difficult to apply force with fingers or tools, which may damage the buckle. Using a push-pull type high-density connector may cause adjacent connectors to detach from the panel, accidentally touch adjacent connectors and cause link interruption, affecting the plugging and unplugging efficiency of the optical fiber connector. Therefore, we propose a fast optical fiber connector to solve the existing problems. Summary of the Invention

[0004] The object of the present invention is to address the problems in the background art that the gap between connectors is too small, it is difficult to apply force with fingers or tools, which may damage the buckle, using a push-pull type high-density connector may cause adjacent connectors to detach from the panel, accidentally touch adjacent connectors and cause link interruption, affecting the plugging and unplugging efficiency of the optical fiber connector, and propose a fast optical fiber connector.

[0005] To achieve the above object, the present invention provides the following technical solution: A fast optical fiber connector, including a panel, connectors, extrusion rods, and springs. The panels are distributed at equal intervals. Assembly grooves one and two are respectively formed inside both ends of the panel. A spring is connected between the assembly groove one and the assembly groove two. Installation grooves one and two are respectively formed on both sides of the upper end of the panel. A rotating seat is embedded in the inner wall of the lower end of the installation groove one. A rotating shaft is rotatably installed inside the upper end of the rotating seat. A rotating rod is provided at the upper end of the rotating shaft. Symmetrically distributed extrusion rods are provided on the outer wall of the rotating shaft. Equally spaced interfaces are formed at both ends of the panel. Connectors are inserted into the interfaces. One end of the connector is provided with an optical fiber sheath.

[0006] Preferably, guiding surfaces distributed oppositely are formed inside both the installation groove one and the installation groove two. During the rotation of the extrusion rods, the guiding surfaces guide the rotating extrusion rods. The extrusion rods extrude the panels that are fitted together and move away from each other outwardly.

[0007] Preferably, a shelving groove is provided between the guiding surfaces, the distance between the guiding surfaces gradually decreases from the center to the shelving groove, and both ends of the extrusion rod are located inside the shelving groove. When the panels are fitted together, both ends of the extrusion rod are located inside the shelving groove, and the extrusion rod is placed in order by the shelving groove, preventing the extrusion rod from applying an extrusion force to the panels.

[0008] Preferably, clamping grooves are provided at the joints of the guiding surfaces, and arc surfaces are provided at the joints of the clamping grooves and the guiding surfaces. After the extrusion rod enters the clamping groove through the guiding surface, the extrusion rod is positioned, enabling the extrusion rod to obtain temporary positioning, and at this time, the panels fitted together are temporarily positioned after being unfolded. During the process of the guiding surface entering the clamping groove through the arc surface, the resistance when the clamping groove squeezes the extrusion rod in and out of the clamping groove is reduced.

[0009] Preferably, a socketing groove is provided on one inner wall of the second installation groove, and the socketing groove is socketed on the outer side of the rotating seat. When the panels are fitted together, the first installation groove and the second installation groove are fitted and docked, and the socketing groove is socketed on the outer side of the rotating seat, effectively placing the rotating seat after the first installation groove and the second installation groove are docked.

[0010] Preferably, a guide rod inserted into the spring is provided at one end of the first assembly groove, and a sleeve socketed on the outer sides of the spring and the guide rod is provided at one end of the second assembly groove. During the telescoping process of the spring, the guide rod slides inside the sleeve, limiting the telescoping spring to prevent the spring from shifting, and the guide rod and the sleeve are slidably installed to guide the panels moving relatively or away from each other.

[0011] Preferably, a pressing block is provided on one side of the upper end of the connector, and anti-slip particles are evenly distributed on the upper end of the pressing block. By pressing the pressing block and applying a force to the connector, the insertion and extraction of the connector are forced. During insertion and extraction, the anti-slip particles improve the anti-slip property of the skin and increase the fitting tightness with the hand.

[0012] Preferably, a central block is provided on one side of the panel, a clamping block is provided at one end of the central block, and an extrusion block located on one side of the clamping block is provided on the outer wall of one side of the panel.

[0013] Preferably, brackets symmetrically distributed on one side of the interface are provided at one end of the panel, and a mounting shaft with both upper and lower ends rotatably installed inside the brackets is inserted into the central block. The brackets provide rotational support for the mounting shaft. When the connector during the insertion and extraction process squeezes the clamping block through the extrusion block, the central block is driven to rotate around the mounting shaft as the axis, and the clamping block provides a positioning effect for the passing extrusion block.

[0014] Preferably, torsion springs symmetrically distributed and connected to the central block and the brackets respectively are socketed on the outer side of the rotating shaft. When the mounting shaft rotates, a torsional force is applied to the torsion springs, enabling the clamping block to be elastically supported torsionally and positioning the extrusion block.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. When the optical fiber installed inside the optical fiber sheath and connected to the connector is connected to the panel, the optical fiber is assembled by inserting the connector into the interface of the panel. When the optical fiber connector is pulled out, the panel is elastically connected to a plurality of single-interface panels through springs. By grasping the rotating rod to drive the extrusion rod to extrude the connection part of the panel, the panel at the connector is relatively opened, the distance between the connectors is expanded, the assembly space of the optical fiber connector is expanded, and it is avoided that the adjacent optical fiber connectors are taken out when pulling out the optical fiber connector, making the plugging and unplugging of the optical fiber connector stable and convenient.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Such as Figures 1 - 5As shown in the figure, a fast fiber optic connector proposed by the present invention includes a panel 1, a connector 4, a pressing rod 15, and a spring 16. The panels 1 are evenly distributed. Inside both ends of the panel 1, an assembly groove 17 and an assembly groove 20 are respectively arranged. A spring 16 is connected between the assembly groove 17 and the assembly groove 20. On both sides of the upper end of the panel 1, an installation groove 2 and an installation groove 28 are respectively arranged. Inside the inner wall of the lower end of the installation groove 2, a rotating seat 12 is embedded. Inside the upper end of the rotating seat 12, a rotating shaft 13 is rotatably installed. At the upper end of the rotating shaft 13, a rotating rod 14 is arranged. On the outer wall of the rotating shaft 13, symmetrically distributed pressing rods 15 are arranged. At both ends of the panel 1, evenly distributed interfaces 3 are arranged. Inside the interfaces 3, connectors 4 are inserted. At one end of the connector 4, an optical fiber sheath 5 is arranged;

[0025] Inside both the installation groove 2 and the installation groove 28, guiding surfaces 9 distributed oppositely are arranged;

[0026] Between the guiding surfaces 9, a placing groove 8 is arranged. The distance between the guiding surfaces 9 gradually decreases from the center to the placing groove 8. Both ends of the pressing rod 15 are located inside the placing groove 8;

[0027] At the joints of the guiding surfaces 9, clamping grooves 10 are arranged. At the joints of the clamping grooves 10 and the guiding surfaces 9, arc surfaces 11 are arranged;

[0028] On one inner wall of the installation groove 28, a socketing groove 27 is arranged. The socketing groove 27 is socketed on the outer side of the rotating seat 12;

[0029] At one end of the assembly groove 17, a guide rod 18 inserted into the spring 16 is arranged. At one end of the assembly groove 20, a sleeve 19 sleeved on the outer sides of the spring 16 and the guide rod 18 is arranged;

[0030] On one side of the upper end of the connector 4, a pressing block 6 is arranged. On the upper end of the pressing block 6, evenly distributed anti-slip particles 7 are arranged;

[0031] On one side of the panel 1, a center block 23 is arranged. At one end of the center block 23, a clamping block 25 is arranged. On the outer wall of one side of the panel 1, an extrusion block 26 located on one side of the clamping block 25 is arranged;

[0032] At one end of the panel 1, brackets 21 symmetrically distributed on one side of the interface 3 are arranged. Inside the center block 23, a mounting shaft 24 rotatably installed at both the upper and lower ends inside the brackets 21 is inserted;

[0033] On the outer side of the rotating shaft 13, symmetrically distributed torsion springs 22 with both ends respectively connected to the center block 23 and the brackets 21 are sleeved;

[0034] Implementation steps based on Embodiment 1: Before use, the optical fiber is connected to the connector 4 and is located inside the optical fiber sheath 5. It is connected to the connector 4 through the optical fiber sheath 5 to ensure that the optical fiber can be firmly inserted into the connector 4 for protecting the optical fiber. Subsequently, the connector 4 is aligned with the interface 3 on the panel 1, and a gentle force is applied to insert the connector 4. When the connector 4 needs to be pulled out, by grasping and rotating the rotating rod 14, the rotating shaft 13 and the extrusion rod 15 thereon are driven to rotate. During the rotation of the extrusion rod 15, it moves along the guiding surface 9 inside the installation groove. Since the distance between the guiding surfaces 9 gradually decreases from the center to the placement groove 8, the two ends of the extrusion rod 15 gradually move outward under the guidance of the guiding surface 9, thereby applying an extrusion force to the connection part of the panel 1, causing the originally closely fitting panel 1 to open relatively, and expanding the distance between the connectors 4;

[0035] Utilizing the elastic effect of the spring 16, the spring 16 is arranged between the assembly groove one 17 and the assembly groove two 20 inside the two ends of the panel 1. When the extrusion rod 15 applies an extrusion force to the panel 1, the spring 16 is compressed, and a gap appears between the panels 1, providing sufficient operating space for pulling out the connector 4. At the same time, the arrangement of the guide rod 18 and the sleeve 19 ensures the stability of the spring 16 during the telescopic process, avoiding deviation, and providing guidance for the relative or opposite movement of the panel 1;

[0036] The advantages of this quick optical fiber connector 4 are that it significantly improves the plugging and unplugging efficiency of the optical fiber connector 4. Through the design of the rotating rod 14 and the extrusion rod 15, the operator does not need to directly apply force to the connector 4, avoiding the problems of difficult force application or damage to the buckle due to too small a gap of the connector 4. At the same time, the control of the panel 1 by the extrusion rod 15 effectively prevents accidental touch of adjacent connectors 4, reducing the risk of link interruption. In addition, the design of the pressing block 6 and its anti-slip particles 7 at the upper end of the connector 4 further improves the anti-slip property and stability during the plugging and unplugging process;

[0037] Aiming at the problems of small gap and difficult plugging and unplugging of the connector 4, through the design of the extrusion rod 15 and the panel 1, the distance between the connectors 4 can be flexibly adjusted, providing convenience for the plugging and unplugging operation. Secondly, it avoids the problem of adjacent connectors 4 being disengaged that may be caused by the push-pull type high-density connector 4, ensuring the stability and reliability of the optical fiber connection. Through the precise control of the rotating rod 14 and the extrusion rod 15, accidental touch of adjacent connectors 4 is effectively prevented, thereby improving the overall use efficiency and safety of the optical fiber connector 4.
