[0021] The following will refer to Figures 1 to 13 Various embodiments of the present invention are described in detail.

[0022] A shockproof buffer device for an optical fiber active connector, such as Figure 1 , Figure 5 , Figure 8 , Fig. 9 As shown, it includes a left movable connector 1 and a right movable connector 2, the right end of the left movable connector 1 is fixedly installed with a left joint 3, and the left end of the right movable connector 2 is fixedly installed with a right joint 4, the left joint 3 and the right joint 4 can be installed in a buckled manner with each other, the upper parts of the left movable connector 1 and the right movable connector 2 are installed with a semi-cylindrical shell 5, and the lower parts are installed with a semi-cylindrical shell 5, after the two semi-cylindrical shells 5 are closed, a complete cylindrical shape is formed, the interior of the semi-cylindrical shell 5 is a cavity structure, and the two ends of the semi-cylindrical shell 5 are semi-circular ring structures, and a plurality of sliding circular holes are evenly and slidably installed on the outer wall of each of the semi-cylindrical shells 5, and the plurality of sliding circular holes in the same row between the left and right sides are arranged on the outer wall of the semi-cylindrical shell 5. Sliding rods 6 are installed inside respectively, and the sliding rods 6 can slide freely inside the corresponding sliding circular holes. The outer ends of the plurality of sliding rods 6 in the same row between the left and right sides are fixedly installed with protective plates 7. The protective plates 7 are arranged horizontally. A plurality of shock-absorbing springs 8 are fixedly installed between the inner wall of each of the protective plates 7 and the outer wall of the semi-cylindrical shell 5. Four shock-absorbing springs 8 are arranged here. A compression shell 9 is fixedly installed on the inner wall of each of the protective plates 7. Each shock-absorbing spring 8 is arranged inside the cavity of the compression shell 9. The compression shell 9 has the characteristics of compression and automatic reset. The two semi-cylindrical shells 5 are connected by a locking device. Optical fibers 10 are installed inside the left movable connector 1 and the right movable connector 2 respectively. The personnel hold the left movable connector 1 and the right movable connector 2, and install them together by buckling the left joint 3 and the right joint 4, wherein one of the semi-cylindrical shells 5 is buckled on the outer ends of the upper halves of the left movable connector 1 and the right movable connector 2, and the other semi-cylindrical shell 5 is buckled on the outer ends of the lower halves of the left movable connector 1 and the right movable connector 2, and the two semi-cylindrical shells 5 are fixed by a locking device, and the left movable connector 1 and the right movable connector 2 are hidden between the two semi-cylindrical shells 5; When the left movable connector 1 and the right movable connector 2 are collided by external force, the protective plate 7 is first squeezed by the external force, and the corresponding protective plate 7 will squeeze the shock-absorbing spring 8 and the compression shell 9 for compression, and at the same time the sliding rod 6 will slide close to the left movable connector 1 and the right movable connector 2. At this time, the shock-absorbing spring 8 and the compression shell 9 can play a shock-absorbing and buffering role for the left movable connector 1 and the right movable connector 2, avoiding damage to the semi-cylindrical shell 5 and the inner parts, thereby improving the service life of the left movable connector 1 and the right movable connector 2. The setting of the sliding rod 6 can guide the compression shell 9 and the shock-absorbing spring 8 to be compressed and reset straightly during the compression process without deviation, which can protect the compression shell 9 and the shock-absorbing spring 8. When the left movable connector 1 and the right movable connector 2 are squeezed by external force, the protective plate 7 is squeezed by the external force first, and the protective plate 7 will compress the shock-absorbing spring 8 and the compression shell 9 accordingly. At the same time, the sliding rod 6 will slide closer to the left movable connector 1 and the right movable connector 2. At this time, the shock-absorbing spring 8 and the compression shell 9 can exert an outward reverse force on the protective plate 7 to avoid damage to the semi-cylindrical shell 5 and the inner parts, thereby improving the service life of the left movable connector 1 and the right movable connector 2. The setting of the sliding rod 6 can guide the compression shell 9 and the shock-absorbing spring 8 to During the compression process, the spring 8 can only be compressed and reset in a straight line without any deviation, which can protect the compression shell 9 and the shock-absorbing spring 8. When the external force disappears, the shock-absorbing spring 8 and the compression shell 9 can push the protective plate 7 to reset. By setting the shock-absorbing spring 8 and the compression shell 9, the semi-cylindrical shell 5 can be well protected to prevent the left movable connector 1 and the right movable connector 2 from being damaged; if the protective plate 7 is suddenly hit or falls to the ground, the shock-absorbing spring 8 and the compression shell 9 also protect the connector.

[0023] like Figure 1 , Figure 3 , Figure 5 As shown, rubber blocks 11 are fixedly installed on the inner walls of the semicircular rings at both ends of each semi-cylindrical shell 5, and the rubber blocks 11 are of a semi-cylindrical structure and have the characteristics of compression and resetting. Anti-aging shells 12 are installed on the outer surfaces of both ends of each semi-cylindrical shell 5, and the anti-aging shells 12 are of a semi-cylindrical structure, and the inner wall of the anti-aging shell 12 contacts the outer wall of the rubber block 11. Each of the anti-aging shells 12 is fixedly connected to the semi-cylindrical shell 5 by positioning screws 13; The personnel hold the left movable connector 1 and the right movable connector 2, and install them together by buckling them together through the left joint 3 and the right joint 4, wherein one of the semi-cylindrical shells 5 is buckled on the outer ends of the upper halves of the left movable connector 1 and the right movable connector 2, and the other semi-cylindrical shell 5 is buckled on the outer ends of the lower halves of the left movable connector 1 and the right movable connector 2, and the inner circular surfaces of the four rubber blocks 11 are seamlessly installed on the outer end circular surfaces of the left movable connector 1 and the right movable connector 2, and then the locking device fixes the two semi-cylindrical shells 5, at which time the rubber blocks 11 can be tightly pressed on the corresponding outer end circular surfaces of the left movable connector 1 and the right movable connector 2, so that the two semi-cylindrical shells 5 can be firmly installed on the outer sides of the left movable connector 1 and the right movable connector 2, thereby improving the stability of the connectors; If the connector is hit, the semi-cylindrical shell 5 will not detach from the connector, and the rubber block 11 can also seal the two ends of the semi-cylindrical shell 5 to prevent external impurities from entering the interior of the semi-cylindrical shell 5 and affecting the transmission effect of the optical fiber 10. Since the semi-cylindrical shell 5 and the anti-aging shell 12 are provided on the outside of the connector, the aging speed of the connector is slowed down and the service life is increased.

[0024] like Figure 2 , Figure 7 , Fig.13 As shown, a positioning shell 14 is fixedly installed inside the semicircular rings at both ends of each of the semi-cylindrical shells 5, and the positioning shell 14 is a semicircular ring structure. A mounting cavity is opened on the corresponding ends of each two positioning shells 14, and six isolation blocks 15 are evenly fixedly installed inside each mounting cavity. A mounting groove 16 is provided between each two isolation blocks 15 on the same side, and a ventilation box 17 is fixedly installed on the inner bottom of each mounting groove 16. A compressed air bag 18 is fixedly installed on the top of each ventilation box 17. The ventilation box 17 and the compressed air bag 18 are connected. Under normal circumstances, the compressed air bag 18 is filled with air. The compressed air bag 18 has the characteristics of compression and resetting, and an expansion device is provided between the two ventilation boxes 17 located in the same direction.

[0025] like Figure 4 , Figure 7 As shown, a pressure strip 19 is installed between two installation grooves 16 located in the same direction between the left and right sides. The pressure strip 19 can slide freely inside the installation groove 16. The pressure strip 19 is arranged at the outer side of the compression airbag 18. A plurality of circular plates 20 are fixedly installed on each of the pressure strips 19, and each of the sliding rods 6 is arranged correspondingly to the circular plate 20 below.

[0026] like Figure 2 , Figure 7 , Fig.11 As shown, the expansion device includes a vent pipe 21, and the outer end of each vent box 17 is fixedly penetrated by a vent pipe 21, and the outer end of each vent pipe 21 is fixedly penetrated by a through plate 22, and a fixed plate 23 is fixedly installed between two through plates 22 located in the same direction between the left and right sides, and the interior of the fixed plate 23 is a cavity structure, and each through plate 22 is connected with the fixed plate 23, and an expansion airbag 24 is fixedly installed on the bottom end of each fixed plate 23, and the expansion airbag 24 is connected with the fixed plate 23; When the left movable connector 1 and the right movable connector 2 are squeezed by external force or the collision force is large, the protective plate 7 is squeezed by the external force first, and the corresponding protective plate 7 will quickly squeeze the shock-absorbing spring 8 and the compression shell 9, and at the same time the sliding rod 6 will slide closer to the left movable connector 1 and the right movable connector 2, and the sliding rod 6 pushes the circular plate 20 and the pressure plate strip 19 to approach the connector, and the pressure plate strip 19 compresses the corresponding compression airbag 18, and the air inside the compression airbag 18 enters the inside of the expansion airbag 24 through the ventilation box 17, the ventilation pipe 21 and the fixing plate 23, so that the expansion airbag 24 quickly expands and lengthens in the direction of the connector, so that the outer end face of the expansion airbag 24 squeezes the outer end face of the connector and protects the outer side face of the connector, and the outer surface of the connector forms a protective barrier, so that the connection between the two connectors is more stable; After the expansion airbag 24 expands to a certain extent, there will be an inward contraction force. When this contraction force reaches a balance with the air compression force of the compression airbag 18, the air inside the compression airbag 18 no longer enters the expansion airbag 24, and the external protective plate 7 no longer moves toward the connector, thereby playing a protective and stabilizing role for the connector. At the same time, the shock-absorbing spring 8 and the compression shell 9 can also give the protective plate 7 an outward reverse elastic force to avoid damage to the semi-cylindrical shell 5 and the inner components, thereby improving the service life of the left movable connector 1 and the right movable connector 2.

[0027] like Figure 4 , Fig.11 , Fig.12 As shown, pressure rods 25 are fixedly installed on the inner sides of the two ends of the pressure strip 19 near one end of the semi-cylindrical shell 5, and two symmetrical pressure rods 25 are fixedly connected to the two ends of each other pressure strip 19 (the installation position of the pressure rod 25 is as shown in FIG. Figure 7 As shown in the figure, a limiting block 26 is fixedly installed on the isolation block 15 between each two pressure plate strips 19, and a limiting hole is provided on the limiting block 26. A sliding bar 27 is slidably installed inside each limiting hole. A cross block 28 is fixedly installed on the top of each sliding bar 27, and each pressure rod 25 is placed on the top of the corresponding cross block 28; A return spring 29 is fixedly installed on the top of each cross block 28, a positioning block 30 is fixedly installed on the top of each return spring 29, the positioning block 30 is fixedly installed on the corresponding isolation block 15, a cross bar 31 is fixedly installed on the bottom end of each sliding bar 27, a pressure block 32 is fixedly installed on the bottom end of the other side of each cross bar 31, and a thrust device located below the pressure block 32 is provided between every two pressure plate strips 19.

[0028] like Figure 7 , Fig.13As shown, the thrust device includes an ear plate 33, and an ear plate 33 is fixedly installed on the isolation block 15 between each two pressure plate strips 19. The ear plate 33 is arranged at a position below the corresponding limiting block 26. A swing link 34 is rotatably installed on each ear plate 33, and a torsion spring is arranged between the swing link 34 and the ear plate 33. Due to the arrangement of the torsion spring, the free end of the swing link 34 is swung and raised toward the semi-cylindrical shell 5, and a locking rod 35 is rotatably installed on the other end of each swing link 34. A tension spring is fixedly installed on the inner end of the locking rod 35, and the other end of the tension spring is fixedly installed on the corresponding swing link 34. Due to the force of the tension spring, the swing link 34 at this time An included angle is formed between the inner end of the locking rod 35, and the angle is between 110 degrees and 130 degrees, and is 120 degrees under normal conditions. A sliding shaft 36 is fixedly installed on the other end of each locking rod 35, and a clamping rod 37 is slidably installed on the other end of each sliding shaft 36. A pressure spring 38 is sleeved on each sliding shaft 36, and one end of the pressure spring 38 is fixedly installed on the clamping rod 37, and the other end is fixedly installed on the locking rod 35. A locking arc plate 39 is rotatably installed on the other end of each clamping rod 37. After the expansion airbag 24 expands and becomes longer, it will not affect the normal use of the locking arc plate 39. A friction pattern is provided on the inner end surface of the locking arc plate 39; When the left movable connector 1 and the right movable connector 2 are squeezed by external force or the collision force is large, the protective plate 7 is squeezed by the external force first, and the corresponding protective plate 7 will quickly squeeze the shock-absorbing spring 8 and the compression shell 9 to compress. At the same time, the sliding rod 6 will slide closer to the left movable connector 1 and the right movable connector 2, and the sliding rod 6 pushes the circular plate 20 and the pressure plate strip 19 to approach the connector. At the same time, the pressure rod 25 presses the cross block 28 to slide, the return spring 29 is stretched, the sliding bar 27 pushes the cross bar 31 to slide, the pressure block 32 presses the corresponding swing link 34 to swing, the torsion spring twists and accumulates force, and the locking rod 35 pushes the sliding shaft 36 to slide to the inside of the clamping rod 37 At the same time, the pressure spring 38 is compressed, and the clamping rod 37 pushes the locking arc plate 39 to contact the outer side of the connector. At this time, multiple locking arc plates 39 on the left side push the left active connector 1 to move to the right, and multiple locking arc plates 39 on the right side push the right active connector 2 to move to the left. At this time, the left active connector 1 and the right active connector 2 are in close contact with each other, thereby providing a stable state for the transmission of the optical fiber 10. Since the inner end surface of the locking arc plate 39 is provided with textures, the locking arc plate 39 at this time will be firmly attached to the outer side of the connector, thus avoiding misalignment of the two optical fiber pins and affecting the use of the optical fiber 10.

[0029] like Figure 1 , Fig.10As shown, the locking device includes a bending plate 40 and a locking frame 42, wherein the bending plates 40 are fixedly installed on the semicircular rings at both ends of one of the semi-cylindrical shells 5, and the bending plates 40 are L-shaped structures and have elastic characteristics. An inclined block 41 is fixedly installed on the other end of each of the bending plates 40, and the locking frames 42 are fixedly installed on the semicircular rings at both ends of the other semi-cylindrical shell 5, respectively. The locking frames 42 are arranged corresponding to the bending plates 40, and a socket is opened on the locking frame 42, and a locking nail 43 is threadedly installed on each of the locking frames 42; The personnel hold the two semi-cylindrical shells 5 and gradually move them closer to the left movable connector 1 and the right movable connector 2. Each inclined block 41 is inserted into the inside of the socket respectively. At this time, each bending plate 40 will deform and gradually move closer to the semicircular ring. When the two semi-cylindrical shells 5 are fully engaged on the left movable connector 1 and the right movable connector 2, due to the rebound force of the bending plate 40, each inclined block 41 will come out of the socket, and then be clamped on one end of the locking frame 42, so that the two semi-cylindrical shells 5 are firmly attached to the left movable connector 1 and the right movable connector 2. The rotating locking pin 43 presses the bending plate 40 to avoid separation of the two semi-cylindrical shells 5 when they collide. The setting of the locking pin 43 further improves stability.

[0030] like Figure 2 , Figure 3 , Figure 5 As shown, locking arc plates 39 are respectively provided on the left side of the left joint 3 and the right side of the right joint 4. The outer diameters of the left joint 3 and the right joint 4 are the same, and the outer diameter of the right joint 4 is larger than the outer diameters of the left movable connector 1 and the right movable connector 2. When the locking arc plate 39 continues to slide toward the contact surface of the left movable connector 1 and the right movable connector 2, it will be blocked by the left joint 3 or the right joint 4, so that the two left joints 3 or the right joints 4 are in close contact, further improving the stability of the two connectors. Each of the expansion airbags 24 is respectively arranged on the outside of the left movable connector 1 and the right movable connector 2, so that the two connectors can be squeezed conveniently, further improving the stability of the connectors.
