Technical Field

[0001] The present application relates to the field of optical fiber connectors, and more specifically, to an optical fiber plastic connector assembly. Background Art

[0002] Optical fiber is the abbreviation of optical fiber, which is a fiber made of glass or plastic that can be used as a light transmission tool. The transmission principle is "total reflection of light", and the optical fiber connector is a connecting part that connects two optical fibers permanently or detachably and has protective components. The optical fiber connector is the end device of the optical fiber.

[0003] The patent with application number 202021352788.X discloses a fiber optic connector assembly, including an optical fiber and a tailstock, the tailstock is cylindrical, the tailstock is sleeved on the outside of the optical fiber, and a plurality of locking mechanisms fixed to the optical fiber are arranged on the outer wall of the tailstock, both ends of the optical fiber pass through the tailstock, and the inner wall of the port of the tailstock away from the optical fiber is evenly distributed with a first thread, and the port of the tailstock is connected with a connector, and the connector includes a first bobbin, the first bobbin is rotatably connected in the port of the tailstock, and the outer wall of the first bobbin is evenly distributed with a second thread connected with the first thread. A hexagonal column is fixedly connected to the side wall of the first bobbin away from the tailstock. The application can use the limiting bobbin to limit the optical fiber core, ensure that the core is in a concentric position, and realize the flexible transmission of single-fiber high-power laser by optical fiber.

[0004] In view of the above-mentioned related technologies, the limiting tube and the support rod are fixedly arranged inside the first tube, but it can only limit the optical fiber of one thickness and may not be able to limit the optical fibers of different thicknesses. Therefore, we propose an optical fiber plastic connector assembly. Utility Model Content

[0005] In order to solve the above problems, the present application provides an optical fiber plastic connector assembly, which adopts the following technical solutions:

[0006] A fiber optic plastic connector assembly comprises a connector body, the connector body comprises a splicing end and a connecting end arranged on one side of the splicing end, a screw groove is provided on the side of the splicing end close to the connecting end, a first thread tooth matching the screw groove is provided on the side wall of the connecting end close to the splicing end, a fixing component is provided on the side of the splicing end away from the connecting end, a slot is provided on the side of the connecting end close to the splicing end, a mounting tube is rotatably installed in the slot, and a limiting component is provided on the inner wall of the mounting tube.

[0007] By adopting the above technical solution, when the product is used, the staff places the optical fiber in the splicing end, and then fixes the splicing end to the side wall of the optical fiber through the fixing component. Then, the staff places the optical fiber in the slot opened at one end of the connecting end. The slot is provided with a limit component, which can play the role of clamping and positioning the optical fiber. When the optical fiber clamping and positioning is completed, the screw groove opened at one end of the splicing end is screwed with the first thread tooth opened on the side wall of the connecting end to connect the splicing end and the connecting end. Because the mounting tube is rotatably installed inside the slot, when the connecting end is rotated, the limit component and the clamped optical fiber will not rotate synchronously, which helps to prevent the optical fiber from being damaged due to rotation.

[0008] Furthermore, the fixing assembly includes a plurality of fastening blocks arranged on the side of the splicing end away from the connecting end, and the plurality of fastening blocks are distributed in a circular array on the side of the splicing end away from the connecting end. A nut is provided on the outer side of the splicing end, and the fastening block and the side wall of the splicing end are both provided with a second thread tooth matching the nut.

[0009] By adopting the above technical solution, the staff puts the nut on the side wall of the optical fiber, and then places the optical fiber in the splicing end. Then, the staff rotates the nut to make the nut screw into the second thread teeth opened on the fastening block and the side wall of the splicing end, so as to make the inner wall of the fastening block contact with the side wall of the optical fiber, thereby playing the role of fixing the connection between the optical fiber and the splicing end.

[0010] Furthermore, a first rubber pad is fixedly mounted on the inner wall of the fastening block.

[0011] By adopting the above technical solution, the inner wall of the fastening block plays a role in protecting the optical fiber through the arrangement of the first rubber pad, which helps to prevent the optical fiber from being worn.

[0012] Furthermore, the limiting assembly includes three mounting blocks fixedly mounted on the inner wall of the mounting tube, the mounting blocks are provided with movable grooves on the side away from the mounting tube, and the inner walls of the movable grooves are slidably mounted with support blocks, the support blocks are fixedly mounted with clamps on the side away from the mounting tube, the inner walls of the support blocks on the side away from the mounting tube and opposite to the movable grooves in the same group are fixedly mounted with springs distributed in a straight line, and the clamps are fixedly mounted with a second rubber pad on the side away from the mounting tube.

[0013] By adopting the above technical solution, the staff places the optical fiber in the slot opened on one side of the connection end, and the clamp is covered on the side wall of the optical fiber. The clamp is pushed by the spring and the support block to clamp and stabilize the optical fiber. The optical fiber can push the support block to slide into the movable groove through the clamp, thereby playing the role of the distance between the clamp and the mounting block, so that the equipment can clamp and limit optical fibers of different sizes, which is beneficial to improving the practicability of the equipment.

[0014] Furthermore, the support block is fixedly installed with limit blocks on both sides close to one end of the mounting tube, and the inner wall of the movable groove is provided with a limit groove matching the limit block on the same side.

[0015] By adopting the above technical solution, when the support block slides in the movable groove, the support block slides in the limit groove with the limit block. The cooperation between the limit block and the limit groove helps to prevent the support block from detaching from the movable groove, which is beneficial to maintaining the sliding stability of the support block.

[0016] Furthermore, the outer fixed sleeve of the mounting tube is provided with two symmetrically distributed rotating rings, and the inner wall of the slot is provided with rotating grooves matching the rotating rings.

[0017] By adopting the above technical solution, when the staff screws the splicing end and the connecting end together, the installation tube rotates on the inner wall of the slot, which helps to prevent the optical fiber from being damaged due to twisting, and the installation tube slides in the rotating groove with the rotating ring. The cooperation between the rotating ring and the rotating groove is conducive to maintaining the stability of the rotation of the installation tube.

[0018] In summary, this application includes the following beneficial technical effects:

[0019] (1) In the present application, the setting of the limit assembly plays a role in limiting the positioning of the optical fiber, and through the cooperation of the mounting block, the support block, the spring and the clamp, the connector body can clamp and position optical fibers of different sizes, which is beneficial to improving the practicality of the equipment.

[0020] (2) In the present application, by setting up a fixing assembly, the staff places the optical fiber in the splicing end and allows the fastening block cover to be set on the side wall of the optical fiber. Subsequently, the nut and the second threaded teeth opened on the side wall of the fastening block are screwed together to make the inner wall of the fastening block fit tightly with the outer side of the optical fiber, thereby playing the role of fixing the assembled optical fiber.
