Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber connectors, and particularly to a wear-resistant and impact-resistant plastic optical fiber connector and a preparation method thereof. Background Art

[0002] Optical fibers have revolutionized communication. As the use of optical fibers has increased, it has become increasingly important to be able to repeatedly dock optical fibers. To connect two optical fibers together, for example, an optical fiber connector and an optical fiber adapter can be used. The optical fiber connector is usually provided at both ends of the optical fiber and can be inserted into the opening of the optical fiber adapter. The optical fiber adapter has two openings, and each opening is connected to an optical fiber connector. An optical fiber connector is a device for detachably (actively) connecting between optical fibers. It precisely docks the two end faces of the optical fibers so that the optical energy output by the transmitting optical fiber can be coupled into the receiving optical fiber to the greatest extent, and the influence on the system caused by its intervention in the optical link is minimized.

[0003] The existing optical fiber connectors are made of plastic as a whole and are prone to deformation when subjected to external impact forces. After deformation, the optical fiber connectors are likely to damage internal structures such as optical fiber plugs and plug bases, so the use safety of the optical fiber connectors is greatly reduced. In addition, the plugging and unplugging stability and smoothness between the optical fiber plug and the optical fiber connector decrease as the number of plugging and unplugging operations increases, and the use effect of the optical fiber connector is not ideal.

[0004] Therefore, we have proposed a wear-resistant and impact-resistant plastic optical fiber connector, and at the same time, we have also disclosed a preparation method of the wear-resistant and impact-resistant plastic optical fiber connector. Summary of the Invention

Finally, connect the two dust-proof frames to the sides of the first housing and the second housing respectively through bolt groups, and put on wear-resistant sleeves on the surfaces of the first housing and the second housing.

[0011] When installing between an optical fiber plug and an optical fiber connector, by inserting one side of the optical fiber plug into the inside of the optical fiber plug, the bumps on both sides of the optical fiber plug slide inside two grooves respectively until one side of the two bumps slides into the inside of the first movable groove. By using the two bumps to press on the first movable plate, the first movable plate drives the two movable rods to slide to one side. One end of the two movable rods drives the fixed block to slide in the second chute, so that one side of the fixed block slides to one side of the limiting groove. At this time, the limiting block inside the fixed block enters the limiting groove under the thrust of the second spring. Through the mating connection between the limiting block and the limiting groove, a stable connection is formed between the optical fiber plug and the optical fiber connector, and it is not easy for the optical fiber plug and the optical fiber connector to become disengaged, improving the connection stability of the optical fiber connector.

[0017] When detaching the fiber optic plug from the fiber optic connector holder, by pressing the pressing block inside the through hole towards one side of the fiber optic connector holder, one side of the pressing block pushes the second movable plate to slide inside the second movable groove, and the second movable plate drives the pushing block to slide inside the third sliding groove. The pushing block is used to push one side of the movable block, and the pulling rope between the movable block and the limiting block drives the limiting block to slide inside the fixed block, controlling the detachment between the limiting block and the limiting groove.

[0026] 2. Apply pressure to the first movable plate through two bumps on both sides of the optical fiber plug. The first movable plate drives two movable rods to slide to one side.

Use the pushing block to push one side of the movable block. Drive the limit block to slide inside the fixed block through the pull rope between the movable block and the limit block, control the separation between the limit block and the limit groove, and then push the optical fiber plug out of the inside of the optical fiber connection frame under the action of the first spring to realize the separation between the optical fiber plug and the optical fiber connection frame.

The plug base 10 is inserted into the interior of the protective frame 50, and then the protective frame 50 is installed on one side of the first housing 30 and the second housing 40 by means of a bolt group. The protective frame 50 is used to connect the first housing 30 and the second housing 40. At the same time, the plug base 10, the fiber optic connection frame 70, and the fiber optic plug 20 inside the fiber optic connector are safely protected by using the protective frame 50 and the support frame 90, so as to prevent the fiber optic connector from deforming after being impacted by the outside world, and improve the use safety performance of the fiber optic connector.

The wear-resistant sleeves 120 effectively improve the wear resistance of the fiber optic connector, and the wear-resistant sleeves 120 can buffer the impact force received by the fiber optic connector, thereby playing a certain safety protection effect on the internal first housing 30 and the second housing 40.

[0040] Furthermore, in order to improve the service life of the fiber optic connector, increase the insertion and extraction times of the fiber optic plug 20 inside the fiber optic connector, and improve the connection stability of the fiber optic plug 20 inside the fiber optic connector, bumps 11 are provided on both sides of the fiber optic plug 20, and four limiting grooves 12 are symmetrically arranged on both sides of the fiber optic plug 20. Grooves 13 that cooperate with the bumps 11 are provided on both sides of the inner wall of the fiber optic connection frame 70.
