Description

Technical Field

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

[0002] Fiber optic connectors are devices used to connect optical fibers. They are mainly used in fiber optic communication systems to achieve the transmission of optical signals. The design of fiber optic connectors enables precise docking of optical fibers when connected to reduce signal loss and reflection.

[0003] The Chinese invention with authorization announcement number CN112255736B discloses a waterproof optical cable connector, including a sleeve body, an indoor optical cable is arranged inside the sleeve body, an optical cable guide is arranged at one end inside the sleeve body, an elastic plug mechanism is arranged at the other end inside the sleeve body, a fixed socket shell is arranged on one side of the sleeve body, a sliding socket shell is arranged on the outside of the fixed socket shell away from the sleeve body, and a vacuum sealing structure is arranged between the sleeve body and the fixed socket shell; when the elastic plug mechanism and the socket disclosed in the present invention are plugged into each other, an instantaneous elastic force is generated, so that the plug has sufficient plugging force when inserted, avoiding false contact between the socket and the plug, and after the cavity formed by the sleeve body and the fixed socket shell is evacuated, the vacuum sealing structure continues to maintain the vacuum state to avoid the invasion of external water vapor, and has a very good waterproof effect.

[0004] After the optical cable connector is connected to the optical fiber, it is necessary to use a test device to test the optical fiber signal transmission parameters. When the optical fiber signal transmission parameters do not meet the requirements or there are abnormalities, the ferrule needs to be reinserted into the socket multiple times. The above technical solutions and existing optical cable connectors all adopt an integral plug-in and pull-out method, which has the following defects: (1) Since the optical cable connector adopts a snap-in structure for fixed connection, multiple plug-in and pull-out methods are likely to reduce the service life of the internal snap-in structure; (2) Since the ferrule has an optical fiber built in, the signal is easily disturbed by dust and water vapor in the air. The integral plug-in and pull-out method will prolong the time that the ferrule is exposed to the air, increase the probability of the ferrule end being contaminated with dust or water vapor, and easily affect the stability of the optical fiber connection or signal transmission.

[0043] In the embodiment of the present invention, at the factory stage, the optical cable 3 is embedded in the fixed sleeve 2, the core 32 is embedded in the mounting hole 44 on the surface of the movable sleeve 41, the optical fiber 21 is embedded in the core 32, and the plug-in block 63 is distributed in the socket 52. The third thread 61 and the fourth thread 62 are disengaged from the first thread 14 and the second thread 22 respectively, and one end of the connecting sleeve 6 is in contact with the second retaining ring 24. When the third thread 61 and the fourth thread 62 are connected to the first thread 14 and the second thread 22 respectively, the plug-in block 63 is disengaged from the socket 52, and the other end of the connecting sleeve 6 is in contact with the first retaining ring 16. At this time, when the connecting sleeve 6 is rotated, the plug-in block 63 makes a spiral motion on the outer surface of the rotating sleeve 5, and the first retaining ring 16 and the second retaining ring 24 play a role of axial limiting.

[0044] See also Figure 8 , Fig. 9 , Fig.11 and Fig.13 In one embodiment of the present invention, it also includes an elastic sealing part 7, the elastic sealing part 7 includes a pressure-bearing part 71 and a sealing part 72, the pressure-bearing part 71 includes a connecting piece 711, a sliding rod 712, a boss 713 and a second spring 714, the connecting piece 711 and the boss 713 are fixedly connected at both ends of the sliding rod 712, the sliding rod 712 passes through the movable sleeve 41, the second spring 714 is connected between the boss 713 and the movable sleeve 41, the sealing part 72 includes a sealing ring 721, the connecting piece 711 is in contact with the inner surface of the sealing ring 721, the boss 713 is in sliding contact with the surface of the limiting sleeve 13, and the inner walls of the socket housing 11 and the fixed sleeve 2 are both interference fit with the outer side of the sealing ring 721.

[0045] See also Fig.13 Furthermore, the surface of the limiting sleeve 13 is provided with an inclined step 131 and a bayonet 15, and the limiting card 25 is clamped in the bayonet 15. The plurality of bosses 713 drive the plurality of connecting pieces 711 to move radially by sliding contact with the surface of the limiting sleeve 13, thereby driving the caliber of the sealing ring 721 to expand.

[0046] See also Figure 8 Furthermore, the sealing member 72 further includes an annular shell 722 and a cavity 723 , the sealing ring 721 is movably sleeved in the annular shell 722 , and the connecting piece 71 is distributed in the cavity 723 between the annular shell 722 and the sealing ring 721 .

[0047] In the embodiment of the present invention, the sealing ring 721 is a rubber ring or a silicone ring, and the connecting piece 711 is a hard rubber piece. In the process of pressing the fixed sleeve 2 toward the socket housing 11, the boss 713 slides along the inclined step 131. At this time, the boss 713 is subjected to a radial force from the limiting sleeve 13. The radial force drives a plurality of connecting pieces 711 to perform radial movement through the boss 713 and the sliding rod 712, thereby driving the sealing ring 721 to perform a movement to expand the diameter, so that the sealing ring 721 is squeezed at the joint position between the socket housing 11 and the fixed sleeve 2. Since the radial force generated during installation can make the sealing ring 721 made of rubber or silicone material interference fit with the socket housing 11 and the fixed sleeve 2, it can improve the sealing of the joint position between the socket housing 11 and the fixed sleeve 2, and further improve the waterproof effect.

[0048] Working principle: At the factory stage, the optical cable 3 is embedded in the fixed sleeve 2, the ferrule 32 is embedded in the mounting hole 44 on the surface of the movable sleeve 41, and the optical fiber 21 is embedded in the ferrule 32. The fixed sleeve 2 is held and inserted into the socket housing 11. The limit card 44 first contacts the surface of the limit sleeve 13, and then the fixed sleeve 2 is rotated. Since the ball head 43 penetrates the fixed sleeve 2, the limit card 44 rotates with the fixed sleeve 2. When the limit card 44 is aligned with the bayonet 15, the fixed sleeve 2 is pressed toward the socket housing 11. At this time, the limit card 44 is engaged 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 socket housing 11 and the end face of the fixed sleeve 2 are in contact;

[0049] Then, the optical fiber 31 is tested by the testing equipment. When the test result is unqualified and the ferrule 32 needs to be re-inserted and unplugged for multiple times, the connecting sleeve 6 is rotated on the premise that one end of the connecting sleeve 6 is confirmed to be in contact with the second retaining ring 24. 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 plug block 63 and the socket 52. The rotating rotating sleeve 5 drives the ball head 43, the moving sleeve 41 and the ferrule 32 to move linearly away from the plug socket 12 along the linear guide 23 by slidingly connecting with the ball head 43 through the arc guide rail 53. Thereby, the ferrule 32 is separated from the plug socket 12, and then the rotating sleeve 5 is loosened. The elastic deformation of the first spring 42 drives the ball head 43, the movable sleeve 41 and the ferrule 32 to move in the opposite direction. At this time, the connecting sleeve 6 and the rotating sleeve 5 rotate in the opposite direction, so that the ferrule 32 is inserted into the plug socket 12 again. Compared with the traditional overall plug-in and pull-out method, the present application can reduce the number of times the limit card 44 is engaged, thereby improving the service life. On the other hand, it can reduce the number of times or time that the ferrule 32 is exposed to the air, thereby reducing the probability of the end of the ferrule 32 being 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] When the test is passed, first move the connecting sleeve 6 along the fixed sleeve 2 to disengage the plug-in block 63 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, thereby enhancing the firmness.

[0051] In summary, the present application utilizes a structural design in which the socket assembly 1, the fixed sleeve 2, the plug guide 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 the optical fiber 31 is tested by the test equipment and the ferrule 32 needs to be re-inserted and unplugged for multiple times, the rotating connecting sleeve 6 is driven to rotate through the plug block 63 and the socket 52. The rotating rotating sleeve 5 uses the ball head 43 to drive the ferrule 32 to move in the direction of leaving the plug socket 12. After the connecting sleeve 6 is released, the elastic deformation of the first spring 42 drives the ferrule 32 to move in the opposite direction and be inserted into the plug socket 12 again. Compared with the traditional overall plug-in and pull-out method, the present application can reduce the number of clamping times of the limit card 44 on the one hand, thereby improving the service life. On the other hand, it can reduce the number of times or time that the ferrule 32 is exposed to the air, thereby reducing the probability of the end of the ferrule 32 being 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.
