Description
Technical Field
[0001] The present application relates to the technical field of optical fiber connectors, and in particular to an optical fiber connector connection structure. Background Art
[0002] Fiber-optic communication technology has emerged from optical communication and has become one of the main pillars of modern communications. It plays a vital role in modern telecommunications networks. As an emerging technology, fiber-optic communication has developed at a rapid speed and has a wide range of applications in recent years, which is rare in the history of communications. It is also an important symbol of the world's new technological revolution and the main means of transmitting various information in the future information society.
[0003] The connection between optical fibers and the connection between optical fibers and devices are basically achieved through connectors. Among them, the connection between optical fibers and devices is generally achieved by setting a plug interface on the device and a plug connector at the end of the optical fiber. The plug connector and the plug interface are plugged together to achieve the connection between the optical fiber and the device. The plug-in cooperation of the plug interface and the plug connector has poor anti-detachment performance. Both the device plug interface and the optical fiber plug connector are constructed with a clamping part of plastic material, which is elastically clamped and fixed by using the deformation of its material. When the optical fiber cable is accidentally collided and pulled, it is easy to cause the elastic clamping part to break, making it unable to be effectively clamped, so that the optical fiber plug connector and the device plug interface are loose, and in severe cases, they are separated, thereby affecting the connection transmission of the optical fiber and affecting the normal operation of the equipment. At the same time, it itself uses material deformation for elastic clamping. After frequent plugging and unplugging, its elastic deformation is easy to fail, resulting in an ineffective and stable connection. Therefore, the present application proposes a fiber optic connector connection structure. Summary of the invention
[0004] The purpose of the present application is to solve the problem that the existing connection mechanism between optical fiber and equipment has poor stability and anti-detachment performance, and the present application provides an optical fiber connector connection structure.

DETAILED DESCRIPTION
[0015] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.
[0016] like Figure 1-Figure 8As shown, an optical fiber connector connection structure proposed in an embodiment of the present application includes: an installation frame 1, the installation frame 1 is used to connect with the device, when connected, the installation frame 1 encloses the plug interface on the device, one side of which is provided with a frame body 2, and the opposite sides of the inner wall of the free end of the frame body 2 are provided with sliding grooves 3; two plug-in plates 4 are slidably inserted in the two sliding grooves 3, and the two plug-in plates 4 can block the frame body 2 after sliding and buckling, and the opposite sides of the two plug-in plates 4 are penetrated with a plurality of arc grooves 5, and the corresponding two arc grooves 5 can enclose to form a wire groove for the optical fiber cable to pass through;When the optical fiber connector is plugged into the connector of the device, the two plug plates 4 slide and buckle the frame 2, the connector is located in the frame 2, and the optical fiber moves through the wire groove formed by the two arc grooves 5. Preferably, the diameter of the wire groove formed by the two arc grooves 5 is slightly larger than the diameter of the optical fiber, but smaller than the diameter of the connector. When the two plug plates 4 are buckled, the end of the connector away from the connector contacts and overlaps with the plug plates 4. The shell 6 is slidably sleeved on the frame 2. The outer surface array of the shell 6 is provided with a plurality of anti-slip teeth. The provision of the anti-slip teeth is used to increase the friction between the fingers and the shell 6, making it easier to move the sliding shell 6. The frame 2 has two opposite sides with through grooves 7. The plug plates 4 are each provided with a support plate 8, and the two support plates 8 are each provided with an oblique groove 9, and the two oblique grooves 9 are inclined in opposite directions. The opposite sides of the inner wall of the casing 6 are provided with shaft rods 10, and the two shaft rods 10 are respectively movably passed through the two through grooves 7 and are respectively slidably inserted in the two oblique grooves 9, and a limit spring 11 is connected between the shaft rods 10 and the inner wall of the through groove 7. Preferably, when the two plug plates 4 are buckled to block the frame 2, the two shaft rods 10 are respectively located in the ends of the two oblique grooves 9 with higher inclinations. When the device needs to be connected to the optical fiber, the sliding casing 6 slides upward along the frame 2. At this time, the shaft rod 10 slides along the oblique groove 9. Due to the inclined structure of the oblique groove 9, the shaft rod 10 moves vertically. Therefore, when When the casing 6 moves downward, the shaft rod 10 slides along the inclined groove 9. Under the action of the oblique thrust, the plug plate 4 slides horizontally along the slide groove 3. Since the two support plates 8 are respectively arranged on the two plug plates 4, and the two inclined grooves 9 are inclined in opposite directions, when the casing 6 moves, the shaft rod 10 will squeeze the limit spring 11. Under the resistance of the two shaft rods 10 and the two inclined grooves 9, the two plug plates 4 slide away in opposite directions synchronously, so that the two plug plates 4 release the blockage of the frame 2. At this time, the optical fiber connector can be plugged and connected with the plug interface of the device, so as to realize the connection between the optical fiber and the device. After the optical fiber is connected to the device, the casing 6 is loosened, and under the resistance of the elastic force of the limit spring 11 , the sleeve 6 moves upward to reset, so that the two shafts 10 slide and reset along the two inclined grooves 9 respectively, thereby driving the two plug boards 4 to slide close to each other, thereby blocking the frame 2 again, and the two plug boards 4 resist and limit the optical fiber plug connector. Since the sliding direction of the plug board 4 is perpendicular to the insertion direction of the optical fiber plug connector, and the elastic force of the limit spring 11 is resisted and locked, when the optical fiber is accidentally touched or pulled, the two plug boards 4 are subjected to stress, while the optical fiber plug connector and the device plug interface are not subjected to stress, so that the plug connector is not easy to loosen and disengage, so as to ensure the stability of the connection between the optical fiber and the device, ensure that the device is not easily disturbed by the pulling of the optical fiber, and ensure the normal operation of the device. ;
[0017] like Figure 6As shown, in some embodiments, a vertical rod 12 is provided on the opposite side of the inner wall of the groove 7, the shaft rod 10 is slidably sleeved on the vertical rod 12, and the limit spring 11 is movably sleeved on the vertical rod 12. The vertical rod 12 is provided not only for limiting the vertical movement of the shaft rod 10, but also for guiding the limit spring 11, so that the limit spring 11 can only be elastically compressed and deformed along the axial direction of the vertical rod 12, but cannot be bent in a non-axial direction. That is, the elastic force of the limit spring 11 can be maximized, the elastic force stability of the limit spring 11 is improved, and the stability of the connection between the optical fiber and the equipment is improved.
[0018] like Figure 6 and Figure 8 As shown, in some embodiments, a vertical slot 13 connected to the inclined slot 9 is formed through the support plate 8. Preferably, the vertical slot 13 is connected to the end of the inclined slot 9 with a high inclination. The opposite sides of the two plug plates 4 are overlapped with the opposite sides of the inner wall of the sleeve 6 respectively. When the two plug plates 4 are overlapped with each other, the shaft rod 10 is just located in the end of the inclined slot 9 with a high inclination. Since the vertical slot 13 is connected to the inclined slot 9, and the sleeve 6 can move upward for a distance due to the elastic force of the limiting spring 11, the shaft rod 10 moves vertically upward from the end of the inclined slot 9 with a high inclination, thereby sliding from the inclined slot 9 to the vertical slot 13. In this state, the opposite sides of the two plug boards 4 are overlapped with the opposite sides of the inner wall of the casing 6 respectively, thereby limiting the movement of the two plug boards 4, so that the two plug boards 4 can effectively limit and fix the optical fiber connector. Even if the optical fiber is subjected to an oblique pulling force, it will not cause the plug boards 4 to move, thereby improving the stability of the connection between the optical fiber and the equipment. When it is necessary to open the limit seal of the plug board 4, the casing 6 is slid downward. After the casing 6 moves vertically for a distance, the shaft rod 10 slides along the vertical groove 13 and transitions to the oblique groove 9. After the casing 6 releases the limit on the plug board 4, the plug board 4 can slide horizontally.
[0019] like Figure 8 As shown, in some embodiments, a bearing wheel 14 is fixedly provided on the shaft rod 10, and the bearing wheel 14 is rolled and inserted in the inclined groove 9. Since the shaft rod 10 is limited by the through groove 7 and the vertical rod 12 and can only move vertically, and the inclined groove 9 is opened at an angle, the shaft rod 10 will be subjected to oblique stress when sliding along the inclined groove 9, resulting in a certain friction resistance when the shaft rod 10 slides along the inclined groove 9. By arranging the bearing wheel 14 on the shaft rod 10 and utilizing the rolling overlap of the bearing wheel 14 and the inclined groove 9 to reduce the sliding friction resistance of the shaft rod 10 along the inclined groove 9, the shaft rod 10 slides more smoothly, which not only makes the two plug plates 4 block or release smoothly, but also makes the sliding sleeve 6 smooth, thereby improving practicality.
[0020] like Figure 1As shown, in some embodiments, a plurality of blocking members 15 are provided on the two plug boards 4, and the plurality of blocking members 15 correspond to a plurality of cable troughs respectively. When no optical fiber cable is passed through the cable trough, the blocking member 15 blocks the cable trough. Generally, a plurality of plug interfaces are provided on the equipment for connecting multiple optical fiber cables for network transmission branching, but the plug interfaces are not necessarily all fully plugged in. By setting the blocking member 15, the blocking member 15 blocks the cable trough to which the optical fiber is not plugged, so as to prevent dust and impurities in the outside air from accumulating in the plug interface and affecting the cleanliness of the plug interface, so as to ensure the stability of the connection transmission of the subsequently plugged optical fiber and ensure that it will not be disturbed, thereby improving practicality.
[0021] like Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the blocking member 15 includes: two sealing plates 1501, preferably, the sealing plates 1501 are made of foam or rubber material, and the opposite sides of the two plug plates 4 are provided with grooves 1502 connected to the arc groove 5, and the two sealing plates 1501 are respectively movably inserted in the two grooves 1502, and a resistance spring 1503 is connected between the sealing plates 1501 and the inner wall of the groove 1502. Preferably, when no external force is applied to the sealing plates 1501, under the elastic force of the resistance spring 1503, the sealing plates 1501 partially protrude from the groove 1502, and when the two plug plates 4 are slidably buckled, When no optical fiber is plugged into the plug interface, the two sealing plates 1501 contact each other, blocking the wire groove formed by the two arc grooves 5, and sealing the wire hole to prevent dust. When the two plug plates 4 are slid together and the plug interface is connected to an optical fiber conductor, the two sealing plates 1501 will contact the optical fiber conductor. Under the action of the anti-contact force, the two sealing plates 1501 will slide and shrink into the two grooves 1502 respectively, without affecting the normal passage of the optical fiber conductor. At the same time, the elastic force of the contact spring 1503 and the deformable material of the sealing plate 1501 are used to tightly contact the optical fiber to reduce gaps and improve the dust-proof effect.
[0022] like Figure 4 and Figure 7 As shown, in some embodiments, a socket 16 is provided on the outer surface of one side of the frame 2, and a rod 17 is movably inserted on one side of the casing 6, and the rod 17 is plugged into and matched with the socket 16. When connecting optical fiber wires, since multiple optical fiber wires need to be plugged in, when plugging in the wires, when the casing 6 is slid downward to open and close the two plug boards 4, the rod 17 can be movably inserted into the socket 16, and the casing 6 and the frame 2 are temporarily fixed, and the two plug boards 4 after opening and closing are temporarily fixed, so as to better plug in the optical fiber wires. When all the optical fibers are connected, the rod 17 is pulled out of the socket 16 to release the temporary fixation of the casing 6 and the frame 2, and the casing 6 can be reset under the elastic force of the limit spring 11, so that the plug board 4 can limit and fix the optical fiber, thereby improving practicality.
[0023] like Figure 7 As shown, in some embodiments, a slot 18 is provided on the inner wall of one side of the sleeve 6, and the insertion rod 17 movably passes through the slot 18. A limit plate 19 is fixed on the insertion rod 17 and is slidably inserted in the slot 18. Through the opening of the slot 18 and the setting of the limit plate 19, the two form a limit structure, so that the insertion rod 17 cannot be separated from the sleeve 6, so as to prevent it from being lost. A reset spring 20 mounted on the insertion rod 17 is installed between the limit plate 19 and the inner wall of the slot 18. Spring 20, when the shell 6 is located in the upper half of the frame 2 and the two plug plates 4 are buckled, the end of the plug rod 17 overlaps the surface of the frame 2. At this time, the reset spring 20 is in a compressed state. When the shell 6 slides downward and the plug rod 17 is aligned with the socket 16, under the elastic force of the reset spring 20, the plug rod 17 is movably inserted into the socket 16, thereby automatically fixing the shell 6 to the frame 2. Only when the frame 2 and the shell 6 are released, the plug rod 17 is manually pulled, thereby improving convenience.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
