[0002] A fiber optic connector is a device that makes a detachable (movable) connection between optical fibers. It precisely connects the two end faces of the optical fiber so that the light energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent. Among them, the SC connector is a relatively common fiber optic connector, which is most commonly used on router switches and the optical interface of transmission equipment.

[0003] The common SC connector includes a dust cap, an SC sheath, a main body and a tail sleeve. During installation, the various parts must be disassembled first, and the tail sleeve must be first put on the outside of the prepared optical fiber. After the main structure is opened to clamp the optical fiber, the tail sleeve is used to fix it. During this installation process, it is easy to accidentally touch the already untied optical fiber when putting on the tail sleeve and clamping the optical fiber, causing damage to the optical fiber. As a result, the optical fiber needs to be stripped and cleaned again, which increases the workload in disguise. Therefore, a connector is needed that can make the optical fiber cold connection more fault-tolerant, making the installation process more convenient and the connection more stable.

[0004] In view of the above problems, a clamping mechanism and an optical fiber active connector are proposed to solve the above problems. Utility Model Content

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figure 2 to Figure 4 , which is the first embodiment of the utility model, and this embodiment provides a clamping mechanism, including a connector unit 100, including a connector body 101, a tail clip 102 rotatably arranged at the rear end of the connector body 101, an optical fiber sleeve 103 arranged inside the connector body 101, and a telescopic member 104 sleeved on the outside of the optical fiber sleeve 103, and the telescopic member 104 cooperates with the tail clip 102.

[0033] Furthermore, the front section of the connector body 101 is a rectangular connecting tube 101a, the interior of which is a cylindrical through hole 101a-1, a sleeve positioning block 101a-2 is arranged in the cylindrical through hole 101a-1, which is used to fix the optical fiber sleeve 103, and snap-fit ​​blocks 101a-3 are vertically arranged on both sides of the outside of the rectangular connecting tube 101a, the rear side of the snap-fit ​​block 101a-3 is a snap-fit ​​groove 101a-4, and the rear side of the snap-fit ​​groove 101a-4 is a limit block 101a-5, and the height of the limit block 101a-5 protruding from the outside of the rectangular connecting tube 101a is consistent with the protruding height of the snap block 101a-3, and an inclined slider 101a-6 is also arranged on the upper side of the limit block 101a-5.

[0034] Furthermore, the middle section of the connector body 101 is a rotation adjustment section 101b, and connecting rotation blocks 101b-1 are extended on both sides of its exterior, and the tail clip 102 is rotatably connected to the connecting rotation block 101b-1. When the tail clip 102 cooperates with it, its external dimensions are consistent with the dimensions of the rectangular connecting tube 101a, and telescopic member slide grooves 101b-2 are symmetrically arranged on both sides of the interior of the rotation adjustment section 101b, and the telescopic member 104 cooperates with it and can be slid forward and backward for adjustment. The rear section of the connector body 101 is a fixed tail clip 101c, and card grooves 101c-1 are opened on both sides of its exterior, and a fastening inclined surface 101c-2 is arranged on the lower side. A plurality of fastening circular grooves 101c-3 are also equidistantly arranged inside the fixed tail clip 101c, and the fixed tail clip 101c cooperates with the tail clip 102 to fix the optical cable.

[0035] Furthermore, the optical fiber sleeve 103 is slidably matched with the sleeve positioning block 101a-2, and a fiber hole 103a is opened in the front section of the center position, and the rear section is an optical cable jack 103b. The optical cable jack 103b can clamp the optical cable, and its diameter is slightly smaller than the diameter of the optical cable sheath.

[0036] Furthermore, the tail clip 102 cooperates with the fixed tail clip 101c, and the two have similar structures. A telescopic rod 102a is symmetrically arranged at one end of the tail clip 102. The front end of the telescopic rod 102a is an arc-shaped structure, and an adjustment block 102a-1 is arranged on the outer side of the end. The adjustment block 102a-1 cooperates with the telescopic member 104 to adjust the telescopic structure.

[0037] Furthermore, telescopic sliders 104a are symmetrically arranged on both sides of the telescopic member 104, which cooperate with the telescopic member slide groove 101b-2. An adjustment groove 104a-1 is also vertically opened on the side of the telescopic slider 104a, which is connected with the adjustment block 102a-1. The adjustment block 102a-1 can slide up and down in the adjustment groove 104a-1, and at the same time drive the telescopic slider 104a to slide back and forth in the telescopic member slide groove 101b-2.

[0038] When in use, after the stripped optical fiber is prepared, the tail clamp 102 is opened. During the rotation and opening process, the adjusting block 102a-1 rotates accordingly and slides downward along the adjusting groove 104a-1, while driving the telescopic slider 104a to slide outward in the telescopic member slide groove 101b-2. The telescopic member 104 drives the optical fiber sleeve 103 to move synchronously, so that it extends out of the connector body 101, which is convenient for the insertion of the optical fiber. The optical fiber is inserted into the optical fiber hole 103a, and the optical cable is inserted into the optical cable jack 103b until it can no longer go deeper. At this time, the optical fiber is plugged in place, and the tail clamp 102 is rotated to close. During the closing process, the telescopic rod 102a will drive the telescopic member 104 and the optical fiber sleeve 103 to retract them into the connector body 101 again until the tail clamp 102 is completely closed, which cooperates with the fixed tail clamp 101c to clamp and fix the optical cable.

[0039] Example 2

[0040] Reference Figure 2 to Figure 5 , which is the second embodiment of the utility model, is based on the previous embodiment and provides a clamping mechanism, further comprising a sheath clamping unit 200, comprising a connector sheath 201 arranged on the outside of the connector body 101, and a limiting component 202 cooperating with the connector sheath 201 and the connector body 101.

[0041] Furthermore, the front end of the connector sheath 201 is a connecting sheath 201a, and a directional block 201a-1 is provided at its upper end for determining the connection direction of the device. Engaging through holes 201a-2 are provided on both sides of the connecting sheath 201a, and a limiting baffle 201a-3 is provided at the front end of the engaging through holes 201a-2. The rear end of the connector sheath 201 is a fastening sheath 201b, and its inner side cooperates with the fixed tail clip 101c and the tail clip 102 to clamp the two. Limiting rod grooves 201b-1 are provided on the side walls on both sides of the fastening sheath 201b, which connect the inner and outer sides of the fastening sheath 201b, and the position of the limiting rod groove 201b-1 corresponds to the position of the engaging groove 101c-1.

[0042] Furthermore, the limiting assembly 202 includes a limiting rod 202a, which is rotatably arranged in the limiting rod groove 201b-1. The limiting assembly 202 also includes a spring 202b, one end of which is fixed to the inner wall of the limiting rod groove 201b-1 and the other end cooperates with the limiting rod 202a. The spring 202b provides an elastic force for it.

[0043] Furthermore, the rear end of the limiting rod 202a is a beveled locking block 202a-1, and the front end is an opening and closing block 202a-2. The beveled locking block 202a-1 cooperates with the slot 101c-1 to limit the connection between the connector sleeve 201 and the connector body 101. The opening and closing block 202a-2 extends out of the limiting rod slot 201b-1 to adjust the connection state.

[0044] When in use, after completing the optical fiber plug-in, the connector sheath 201 is connected to the connector body 101. During the connection process, the fastening sheath 201b cooperates with the fixed tail clip 101c and the tail clip 102 to clamp and fasten the two. At the same time, the side wall of the connector body 101 pushes the inclined clamping block 202a-1 to retract it into the limiting rod groove 201b-1. When the limiting rod groove 201b-1 corresponds to the position of the clamping groove 101c-1, the inclined clamping block 202a-1 enters the clamping groove 101c-1 and cooperates with it. At this time, the sheath connection work is completed, and the connecting sheath 201a cooperates with the rectangular connecting tube 101a, which is convenient for inserting into the corresponding interface.

[0045] In summary, when the optical fiber needs to be cold-connected, the tail clamp 102 can be turned to open and the optical fiber sleeve 103 can be brought out at the same time, which can make the positioning and installation of the optical fiber more convenient. After closing the tail clamp 102, the optical fiber sleeve 103 is automatically brought back into the device. The tail clamp 102 can be clamped by the connector sheath 201 to ensure the stability of the optical fiber. The limit assembly 202 can facilitate the disassembly of the device while preventing accidental loosening.

[0046] Example 3

[0047] Reference Figure 1, which is the third embodiment of the utility model, based on the above embodiment, this embodiment further provides an optical fiber active connector. It includes an optical fiber unit 300, an optical cable 301, an optical cable sheath 301a and an optical fiber 301b, and the two ends of the optical cable 301 are respectively connected with a clamping mechanism, which cooperates with the optical fiber sleeve 103 and the tail clip 102.

[0048] When in use, the optical fiber 301b is inserted into the optical fiber hole 103a, and the end of the optical cable sheath 301a is inserted into the optical cable insertion hole 103b until it cannot go deeper, thus completing the connection work with the clamping mechanism.

[0049] In summary, by assembling the clamping mechanism and the optical fiber into an active connector, it is convenient to quickly make a detachable connection between optical fibers and between devices.
