Description

Technical Field

[0001] The present invention relates to the technical field of optical cable connectors, and more particularly to a waterproof and sealed optical cable connector assembly. Background Art

[0002] An optical cable connector is a device used to connect optical fibers, mainly for optical fiber communication systems to achieve the transmission of optical signals. The design of the optical cable connector enables precise docking of optical fibers during connection to reduce signal loss and reflection.

[0003] Patent No. CN112255736B discloses an optical cable connector with good waterproof performance, including a sleeve body. An indoor optical cable is arranged inside the sleeve body. One end inside the sleeve body is provided with an optical cable guide head, and the other end inside the sleeve body is provided with an elastic plug mechanism. One side of the sleeve body is provided with a fixed socket housing, and the outer side of the fixed socket housing away from the sleeve body is provided with a sliding socket housing. A vacuum sealing structure is arranged between the sleeve body and the fixed socket housing. When the elastic plug mechanism and the socket disclosed in the present invention are inserted into each other, an instantaneous elastic force is generated, so that the plug has sufficient insertion force when inserted, avoiding poor contact between the socket and the plug. And after the cavity formed by the sleeve body and the fixed socket housing is evacuated, the vacuum sealing structure continuously maintains this vacuum state to avoid the intrusion of external water vapor, having a very good waterproof effect.

[0004] Since after the optical cable connector connects the optical fibers, test equipment is also needed to test the optical fiber signal transmission parameters. When the optical fiber signal transmission parameters do not meet the requirements or are abnormal, the ferrule needs to be continuously inserted into the socket multiple times. The above technical solutions and existing optical cable connectors all adopt the overall plugging and unplugging method, and this method has the following defects: (1) Since the internal of the optical cable connector uses a clamping structure for fixed connection, the multiple plugging and unplugging method is likely to reduce the service life of the internal clamping structure; (2) Since the ferrule is internally provided with an optical fiber, the signal is easily interfered by dust and water vapor in the air. The overall plugging and unplugging method will prolong the time when the ferrule is exposed to the air, increasing the probability of the end of the ferrule being contaminated with dust or water vapor, and easily affecting the stability of optical fiber connection or signal transmission.

At this time, when the connecting sleeve 6 is rotated, the plug-in blocks 63 perform a spiral movement on the outer surface of the rotating sleeve 5, and the first retaining ring 16 and the second retaining ring 24 play an axial limiting role.

[0044] Please refer to Figure 8 , Figure 9 , Figure 11 and Figure 13 In one embodiment of the present invention, an elastic sealing portion 7 is further included. The elastic sealing portion 7 includes a pressure-bearing member 71 and a sealing member 72. The pressure-bearing member 71 includes a connecting piece 711, a sliding rod 712, a convex platform 713 and a second spring 714. The connecting piece 711 and the convex platform 713 are fixedly connected to both ends of the sliding rod 712. The sliding rod 712 penetrates through the movable sleeve 41. The second spring 714 is connected between the convex platform 713 and the movable sleeve 41. The sealing member 72 includes a sealing ring 721. The connecting piece 711 contacts the inner surface of the sealing ring 721. The convex platform 713 is in sliding contact with the surface of the limiting sleeve 13. The inner walls of the socket housing 11 and the fixed sleeve 2 are both in interference fit with the outer side of the sealing ring 721.

[0045] Please refer to Figure 13 As shown in, further, an inclined step 131 and a bayonet 15 are provided on the surface of the limiting sleeve 13. The limiting card 25 is clamped in the bayonet 15. A plurality of the convex platforms 713 drive a plurality of connecting pieces 711 to perform a radial movement by sliding contact with the surface of the limiting sleeve 13, thereby driving the diameter of the sealing ring 721 to expand.

[0046] Please refer to Figure 8 As shown in, further, the sealing member 72 further includes an annular housing 722 and a cavity 723. The sealing ring 721 is movably sleeved in the annular housing 722. The connecting pieces 711 are distributed in the cavity 723 between the annular housing 722 and the sealing ring 721.

[0047] In an embodiment of the present invention, the sealing ring 721 is a rubber ring or a silica gel ring, and the connecting piece 711 is a hard rubber piece. During the process of pressing the fixing sleeve 2 towards the socket housing 11, the convex platform 713 slides along the inclined step 131. At this time, the convex platform 713 receives a radial force from the limiting sleeve 13. This radial force drives several connecting pieces 711 to perform radial movement through the convex platform 713 and the sliding rod 712, and further drives the sealing ring 721 to perform a movement of expanding the diameter, so that the sealing ring 721 is pressed at the docking seam position between the socket housing 11 and the fixing sleeve 2. Since the radial force generated during installation can make the sealing ring 721 made of rubber or silica gel material have an interference fit with the socket housing 11 and the fixing sleeve 2, the sealing performance at the docking seam position between the socket housing 11 and the fixing sleeve 2 can be improved, and the waterproof effect can be further improved.

[0048] Working principle: At the factory stage, the optical cable 3 is embedded in the fixing sleeve 2, the ferrule 32 is embedded in the mounting hole 44 on the surface of the moving sleeve 41, and the optical fiber 31 is embedded in the ferrule 32. Hold the fixing sleeve 2 and insert it into the socket housing 11. The limit card 44 first contacts the surface of the limiting sleeve 13, and then rotate the fixing sleeve 2. Since the ball head part 43 penetrates the fixing sleeve 2, the limit card 44 rotates following the fixing sleeve 2. When the limit card 44 is aligned with the bayonet 15, press the fixing sleeve 2 towards the socket housing 11. At this time, the limit card 44 is clamped in the bayonet 15, and the ferrule 32 is inserted into the plug socket 12. Under the action of pressure, the first spring 42 is in a compressed state, and the end faces of the socket housing 11 and the pressing fixing sleeve 2 are in contact;

[0049] Then use the testing equipment to test the optical fiber 31. When the test result is unqualified and the ferrule 32 needs to be repeatedly inserted and pulled out continuously for many times, on the premise of confirming that one end of the connecting sleeve 6 contacts the second retaining ring 24, rotate the connecting sleeve 6. Since the third thread 61 and the fourth thread 62 are respectively disengaged from the first thread 14 and the second thread 22 at this time, the rotating connecting sleeve 6 drives the rotating sleeve 5 to rotate through the plugging block 63 and the socket 52. The rotating rotating sleeve 5 drives the ball head part 43, the moving sleeve 41 and the ferrule 32 to perform a linear movement away from the plug socket 12 along the linear guide rail 23 through the sliding connection between the arc-shaped guide rail 53 and the ball head part 43, so that the ferrule 32 is separated from the plug socket 12. Then release the rotating sleeve 5, and the elastic deformation of the first spring 42 drives the ball head part 43, the moving sleeve 41 and the ferrule 32 to move in the reverse direction. At this time, the connecting sleeve 6 and the rotating sleeve 5 rotate in the reverse direction, so that the ferrule 32 is inserted into the plug socket 12 again. Compared with the traditional overall plugging and unplugging method, on the one hand, this application can reduce the clamping times of the limit card 44, thereby improving the service life. On the other hand, it can reduce the number of times or the time that the ferrule 32 is exposed to the air, thereby reducing the probability that the end of the ferrule 32 is contaminated with dust or water vapor, and has the characteristics of improving the service life and improving the connection stability of the optical fiber 31.

[0050] After the test is qualified, first move the connecting sleeve 6 along the fixed sleeve 2 so that the plug block 63 disengages from the socket 52. Since the third thread 61 and the fourth thread 62 are respectively connected to the first thread 14 and the second thread 22 at this time, the connecting sleeve 6 can be fixed between the socket housing 11 and the fixed sleeve 2 by rotating the connecting sleeve 6, which plays a role in enhancing the firmness.

[0051] In summary, the present application uses the structural design in which the socket assembly 1, the fixed sleeve 2, the plug guiding portion 4, the rotating sleeve 5, and the connecting sleeve 6 cooperate with each other. On the premise that the limit card 44 is clamped in the bayonet 15, when it is necessary to repeatedly insert and remove the ferrule 32 continuously for testing the optical fiber 31 using a testing device, the rotating connecting sleeve 6 drives the rotating sleeve 5 to rotate through the plug block 63 and the socket 52. The rotating rotating sleeve 5 drives the ferrule 32 to move in the direction away from the plug base 12 by using the ball head member 43. After releasing the connecting sleeve 6, the elastic deformation of the first spring 42 drives the ferrule 32 to move in the reverse direction and insert into the plug base 12 again. Compared with the traditional overall insertion and removal method, on the one hand, the present application can reduce the clamping times of the limit card 44, thereby improving the service life. On the other hand, it can reduce the number of times or the time that the ferrule 32 is exposed to the air, thereby reducing the probability that the end of the ferrule 32 is contaminated with dust or water vapor, and has the characteristics of improving the service life and improving the connection stability of the optical fiber 31.
