It should be understood that the specific embodiments described herein are only used to explain the present invention and do not limit the present invention.

[0020] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0021] See also Figure 1 and Figure 2 , an optical fiber active connector provided by an embodiment of the present invention, the optical fiber active connector comprising:

[0022] A support shell 1, wherein the support shell 1 is provided with a cavity 2 and a socket, the sockets are arranged on both sides of the cavity 2, and a groove is arranged on the inner wall of the socket provided by the support shell 1; a wire-releasing mechanism 3, which is installed in the cavity 2 provided by the support shell 1, and an optical fiber 4 is passed around the wire-releasing mechanism 3, and both ends of the optical fiber 4 are arranged in the socket provided by the support shell 1 and are fixedly connected with a connecting mechanism 5, which is fixedly arranged in the groove for connecting to the optical fiber head; a locking mechanism 6, which is installed in the groove provided by the support shell 1, and is used to clamp the optical fiber head to maintain the stability of the connection between the optical fiber head and the connecting mechanism 5.

[0023] When using the fiber optic active connector, insert the fiber optic heads of the service line and the extension line into the jacks provided in the support shell 1 until the locking mechanism 6 is inserted into the groove provided in the fiber optic head, thereby completing the fixation of the fiber optic head and the support shell 1. Subsequently, rotate the control end of the pay-off mechanism 3, and the pay-off mechanism 3 can gradually release the optical fiber line 4. Under the elastic force of the connecting mechanism 5 itself, the connecting mechanism 5 can be close to the fiber optic head, thereby achieving the extension of the optical fiber. The data can be transmitted from the service fiber optic head to the extended fiber optic head via the connecting mechanism 5 on the left, the optical fiber line 4, and the connecting mechanism 5 on the right.

[0024] like Figure 1 and Figure 2As shown in the figure, as a preferred embodiment of the present invention, the wire releasing mechanism 3 includes: two guiding wheels 31 which are arranged and installed in the cavity 2 opened in the support shell 1, and the optical fiber wire 4 bypasses the two guiding wheels 31; a pressing and releasing assembly 32 which is installed on the support shell 1, a pressing wheel 33 is fixedly installed on the pressing and releasing assembly 32, the optical fiber wire 4 bypasses the pressing wheel 33, and the pressing and releasing assembly 32 is used to drive the pressing wheel 33 to move to pull the optical fiber.

[0025] As Figure 1 and Figure 2 shown in the figure, as a preferred embodiment of the present invention, the pressing and releasing assembly 32 includes: a threaded barrel 321 which is rotatably installed on the inner wall of the cavity 2 opened in the support shell 1, a turning handle 322 arranged outside the cavity 2 is fixed on the threaded barrel 321, the threaded barrel 321 is threadedly connected with a threaded column 323, a connecting plate 324 is fixedly arranged on the threaded column 323, and the pressing wheel 33 is fixedly installed on the connecting plate 324; a guide post 325 which is fixedly installed on the inner wall of the cavity 2 and distributed on both sides of the threaded barrel 321, and a guide sleeve 326 fixedly connected with the connecting plate 324 is sleeved on the guide post 325.

[0026] When connecting the optical fiber line, rotate the turning handle 322, the turning handle 322 drives the threaded barrel 321 to rotate, the rotation of the threaded barrel 321 can make the threaded column 323 drive the connecting plate 324 and the guide sleeve 326 to move upward along the guide post 325, the upward movement of the connecting plate 324 can drive the pressing wheel 33 to move upward, the connecting mechanism 5 gradually reduces the tension of the optical fiber wire 4, and the connecting mechanism 5 can be attached to the optical fiber head under its own elastic force. During this process, the guiding wheel 31 can play a guiding role for the optical fiber wire 4.

[0027] In this embodiment, the purpose of pressing the optical fiber wire 4 by the wire releasing mechanism 3 is to prevent the optical fiber wires 4 reserved in the cavity 2 from being wound together and affecting the normal data transmission.

[0028] As Figure 4 shown in the figure, as a preferred embodiment of the present invention, the connecting mechanism 5 includes: a sleeve 51 which is fixedly installed on the inner wall of the jack opened in the support shell 1, a sleeve rod 52 is slidably arranged on the sleeve 51, a transmission terminal 53 is fixedly arranged on the sleeve rod 52, and the end of the optical fiber wire 4 is fixedly connected with the transmission terminal 53; a push spring 54 whose two ends are respectively fixedly connected with the transmission terminal 53 and the sleeve 51, and is used to push the transmission terminal 53 to be attached to the optical fiber head.

[0029] As the wire releasing mechanism 3 gradually reduces the pressure on the optical fiber wire 4, under the elastic force of the push spring 54, the transmission terminal 53 can drive the sleeve rod 52 to slide along the sleeve 51, and the transmission terminal 53 can gradually be attached to the optical fiber head, thus completing the connection of the entire optical fiber line.

[0030] As Figure 5As shown, as a preferred embodiment of the present invention, the locking mechanism 6 includes: a sliding column 61 fixedly installed on the inner wall of the groove formed in the support shell 1. A sliding plate 62 is sleeved on the sliding column 61. A connecting block 63 is fixedly arranged on the sliding plate 62. A compression spring 64 is fixedly connected between the sliding plate 62 and the inner wall of the groove; an upward pulling assembly 65 installed at the groove formed in the support shell 1 and fixedly connected to the connecting block 63 for pulling the connecting block 63 and the sliding plate 62 to move upward along the sliding column 61; a locking block 66 fixedly connected to the connecting block 63, and the locking block 66 is used to clamp onto the optical fiber head to lock the optical fiber head.

[0031] When locking the optical fiber head, after inserting the optical fiber head into the jack, the groove on the optical fiber head will gradually align with the locking block 66. When the groove on the optical fiber head is aligned with the locking block 66, under the elastic force of the compression spring 64, the sliding plate 62 can drive the connecting block 63 and the locking block 66 to slide along the sliding column 61, and the locking block 66 can be inserted into the groove, thereby locking the optical fiber head. If the optical fiber head needs to be removed, press the control end of the upward pulling assembly 65, and the upward pulling assembly 65 can drive the connecting block 63, the locking block 66, and the sliding plate 62 to slide along the sliding column 61, so as to drive the locking block 66 to disengage from the groove on the optical fiber head, thus facilitating the removal of the optical fiber head from the jack.

[0032] As Figure 5 shown, as a preferred embodiment of the present invention, the upward pulling assembly 65 includes: a turntable 651 rotatably installed in the groove. A column 652 is fixedly arranged on the turntable 651, and there are two columns 652 and the connecting line passes through the center of the turntable 651; a strip-shaped groove 653 sleeved on the column 652. A connecting column 654 is fixedly arranged on the strip-shaped groove 653. One connecting column 654 is fixedly connected to the connecting block 63, and a pressing handle 655 is fixedly arranged on the other connecting column 654, and the pressing handle 655 extends outside the groove.

[0033] When removing the optical fiber head from the jack, push the pressing handle 655. The pressing handle 655 pushes the connecting column 654 and the strip-shaped groove 653 on one side to move downward. When the strip-shaped groove 653 moves downward, it can push the turntable 651 to rotate counterclockwise through one column 652. When the turntable 651 rotates counterclockwise, it can drive the strip-shaped groove 653 and the connecting column 654 on the other side to move upward through the other column 652. The connecting column 654 on the other side can drive the connecting block 63, the locking block 66, and the sliding plate 62 to slide along the sliding column 61, so as to drive the locking block 66 to disengage from the groove on the optical fiber head.

[0034] As Figure 1 and Figure 2 shown, as a preferred embodiment of the present invention, it further includes: a lead pipe 7 fixedly installed on the support shell 1. The two ends of the lead pipe 7 are respectively arranged in the cavity 2 and the jack, and the optical fiber cable 4 passes through the lead pipe 7.
