DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

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

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

[0022] A supporting 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 provided on the inner wall of the socket provided in the supporting shell 1; a pay-off mechanism 3 is installed in the cavity 2 provided in the supporting shell 1, and an optical fiber 4 is passed around the pay-off mechanism 3, and both ends of the optical fiber 4 are provided in the socket provided in the supporting shell 1 and are fixedly connected to a connecting mechanism 5, which is fixedly provided in the groove for connecting to the optical fiber head; a locking mechanism 6 is installed in the groove provided in the supporting shell 1, for clamping 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 head of the household line and the fiber optic head of the extension line into the jack opened in the support shell 1 until the locking mechanism 6 is locked into the groove opened 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 action of the elastic force of the connecting mechanism 5 itself, the connecting mechanism 5 can be close to the fiber optic head, thereby realizing the extension of the optical fiber. The data can be transmitted from the household fiber optic head to the extended fiber optic head through 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, as a preferred embodiment of the present invention, the pay-off mechanism 3 includes: two guide wheels 31, which are provided and installed in the cavity 2 opened by the support shell 1, and the optical fiber line 4 passes around the two guide wheels 31; a pressing assembly 32, which is installed on the support shell 1, and a pressing wheel 33 is fixedly installed on the pressing assembly 32, and the optical fiber line 4 passes around the pressing wheel 33, and the pressing assembly 32 is used to drive the pressing wheel 33 to move to pull the optical fiber.

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

[0026] When connecting the optical fiber line, the handle 322 is turned, and the handle 322 drives the threaded barrel 321 to rotate. The rotation of the threaded barrel 321 can cause the threaded column 323 to drive the connecting plate 324 and the guide sleeve 326 to move upward along the guide column 325. The upward movement of the connecting plate 324 can drive the pressure wheel 33 to move upward. The connecting mechanism 5 gradually reduces the tension of the optical fiber line 4, and the connecting mechanism 5 can be close to the optical fiber head under the action of its own elastic force. In this process, the guide wheel 31 can guide the optical fiber line 4.

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

[0028] like Figure 4 As shown, as a preferred embodiment of the present invention, the connecting mechanism 5 includes: a sleeve 51, which is fixedly mounted on the inner wall of the jacking hole opened in the support shell 1, a sleeve rod 52 is slidably provided on the sleeve 51, a transmission terminal 53 is fixedly provided on the sleeve rod 52, and the end of the optical fiber line 4 is fixedly connected to the transmission terminal 53; a push spring 54, the two ends of which are respectively fixedly connected to the transmission terminal 53 and the sleeve 51, and are used to push the transmission terminal 53 close to the optical fiber head.

[0029] As the pay-off mechanism 3 gradually reduces the pressure on the optical fiber 4, the transmission terminal 53 can drive the sleeve rod 52 to slide along the sleeve 51 under the elastic force of the push spring 54, and the transmission terminal 53 can gradually fit closely to the optical fiber head, thereby completing the connection of the entire optical fiber line.

[0030] like 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 fiber optic head to lock the fiber optic head.

[0031] When locking the fiber optic head, after inserting the fiber optic head into the jack, the groove on the fiber optic head will gradually be flush with the locking block 66. When the groove on the fiber optic head is flush 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 fiber optic head. If the fiber optic 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 fiber optic head, thus facilitating the removal of the fiber optic 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. There are two columns 652 and the line connecting them 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 fiber optic 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 fiber optic 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 fiber optic cable 4 passes through the lead pipe 7.

[0035] The design of the lead pipe 7 can further guide the optical fiber line 4, avoid the direct contact between the optical fiber line 4 and the support shell 1, reduce the wear of the optical fiber line 4 during long-term use, extend the service life of the connector, enable the connector to be used for a longer time, and improve the satisfaction of users.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
