[0002] An optical fiber connector is a device for detachably connecting optical fibers. It precisely butts 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 maximum extent, and the influence on the system caused by its insertion into the optical link is minimized. This is the basic requirement of the optical fiber connector. To a certain extent, the optical fiber connector affects the reliability and various performances of the optical transmission system.

[0003] When the two end faces of the optical fibers are butted and installed by using the optical fiber connector, generally, one end of the two optical fibers is fixed through a female connection base and a male connection base, and the positions of the female connection base and the male connection base are fixed by using a spring piece or a threaded connection method. However, during use, since the spring piece is generally made of plastic, it is easy to break during the plugging and unplugging process, and it is more inconvenient to install and disassemble by using the threaded connection.

[0022] By inserting the male connection socket 4 into the female connection socket 1, the positioning plate 3 slides in the positioning groove 5 to achieve the quick positioning and installation of the female connection socket 1 and the male connection socket 4. After moving a certain depth, the positioning plate 3 slides with the wedge block 10 and gradually presses the fixing plate 8 into the installation groove 6 along the inclination angle of the wedge block 10, and the first return spring 7 is compressed and contracted. When the inner side of the male connection socket 4 contacts the inner wall of the female connection socket 1, the fixing plate 8 is clamped in the fixing groove 11 under the action of the elastic force of the first return spring 7, so as to realize the connection and fixation of the two optical fibers. Press the pressing plate 13 inward to move the fixing plate 8 downward and into the installation groove 6, and the fixing plate 8 disengages from the fixing groove 11 to pull out the male connection socket 4.

[0023] The number of connection pins 2 is set to be multiple, the positioning plate 3 is located inside the positioning groove 5, the number of the first return springs 7 is set to be four, and the sliding plates 9 are in contact with the inner wall of the installation groove 6.

[0024] A fixing groove 11 is provided at the top of the female connector 1 , a sliding groove 12 is provided on the inner wall of the fixing groove 11 , a pressing plate 13 is slidably connected inside the fixing groove 11 , and sliding blocks 14 are fixedly connected to the left and right sides of the pressing plate 13 .

[0025] There are two slide grooves 12 , and the two slide grooves 12 are matched with the slider 14 , and the pressing plate 13 is in contact with the top of the fixing plate 8 .

After moving a certain depth, the positioning plate 3 slides against the wedge block 10 and gradually presses the fixing plate 8 into the installation groove 6 along the inclination angle of the wedge block 10. The first return spring 7 is compressed and contracted. The male connector base 4 continues to move, and a slider 14 is generated between its inner side and the guiding slope of the limiting block 20, causing the sliding rod 18 to slide on the female connector base 1. The second return spring 19 is compressed and contracted. The inner side of the male connector base 4 slides to the bottom of the guiding slope and the limiting block 20 enters the groove 16. When the inner side of the male connector base 4 contacts the inner wall of the female connector base 1, the fixing plate 8 is snapped into the fixing groove 11 under the action of the elastic force of the first return spring 7. At the same time, the limiting block 20 is snapped into the limiting groove 17 under the action of the elastic force of the second return spring 19, thus realizing the connection and fixation of the two optical fibers.
