Description

Technical Field

[0001] This utility model belongs to the field of optical fiber and cable technology, and more specifically, it relates to a tensile-resistant optical fiber and cable. Background Technology

[0002] Fiber optic cable is a type of communication cable consisting of two or more glass or plastic optical fiber cores. These optical fiber cores are located within a protective cladding and are covered by an outer plastic PVC sheath. Signal transmission along the internal optical fibers typically uses infrared light.

[0003] Existing fiber optic cables typically require connectors at the cable end to connect to equipment. However, these cables are usually directly fixed to the connectors, lacking tensile strength protection at the connection point. Pulling out the cable or connector can easily damage this connection. Therefore, this paper researches and improves upon existing structures and shortcomings to provide a tensile-resistant fiber optic cable with greater practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a tensile-resistant optical fiber cable, which is achieved by the following specific technical means:

[0005] A tensile-resistant optical fiber cable includes a protective sleeve installed on the outside of multiple sets of optical fibers. A fixing plate is fixedly installed on the outside of the protective sleeve. A connecting frame is fixedly installed on both sides of the fixing plate. A clamp is rotatably connected to the inner side of each of the two sets of connecting frames.

[0006] Furthermore, a movable disk is installed on the outer side of the protective sleeve, and connecting brackets are fixedly installed on both sides of the movable disk. Connecting rods are rotatably connected to the inner sides of the two sets of connecting brackets. The fixed disk is provided with two sets of connecting grooves corresponding to the two sets of connecting rods, allowing the connecting rods to move. One end of each of the two sets of connecting rods passes through the two sets of connecting grooves and is rotatably connected to the inner side of the two sets of grippers.

[0007] Furthermore, a clamping plate is installed at one end of each of the two sets of grippers, a connecting pin is fixedly installed on one side of each of the two sets of clamping plates, and a connecting shaft is fixedly installed on the inner side of each of the two sets of connecting pins. The two sets of connecting shafts are rotatably connected to the ends of the two sets of grippers away from the fixed disk.

[0008] Furthermore, a rubber pad is fixedly adhered to one side of each of the two sets of clamps, and anti-slip texture is provided on one side of each of the two sets of rubber pads.

[0009] Furthermore, a threaded cylinder is fixedly installed on the outer side of the protective sleeve, and a threaded seat is threadedly connected to the outer side of the threaded cylinder. The outer side of the threaded seat is rotatably connected to the inner side of the movable disk. One side of the threaded seat abuts against the movable disk. A thread is provided on the outer side of the threaded seat and a limit seat is threadedly connected to it. A plane bearing is installed between the limit seat and the movable disk.

[0010] Furthermore, the outer sides of multiple sets of optical fibers are jointly fixedly connected with a filler.

[0011] Furthermore, multiple sets of steel strands are equidistantly installed on the outer side of the first filler, and the outer sides of the multiple sets of steel strands are fixedly connected to the second filler. The inner side of the second filler is fixedly connected to the first filler, and the outer side of the second filler is fixedly connected to the inner side of the protective sleeve. Both the first filler and the second filler are rubber strips.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model, through the cooperation of the fixing plate and the connecting frame, enables the flexible rotation of two sets of clamps. Through the cooperation of the two sets of clamps, the connector can be clamped between the two sets of clamps, thereby ensuring that when the optical cable and the connector are pulled out, the connection between the connector and the optical cable is not subjected to force, avoiding damage to the connection between the optical cable and the connector, and increasing the service life of the product.

[0014] 2. This utility model can achieve flexible movement of the moving disc by means of the cooperation of the threaded cylinder and the threaded seat. By means of the cooperation of the moving disc and the connecting rod, it can achieve flexible rotation of the gripper. The structure is simple, the processing cost is low, and it is easy to drive the rotation of the gripper. Attached Figure Description

[0029] Among them, rubber pads 8 are fixedly adhered to one side of both sets of clamping plates 7, and anti-slip textures are provided on one side of both sets of rubber pads 8 to prevent slippage between the connector and the clamping plate 7.
