[0002] The optical fiber splicing tray is an important device widely used in the field of optical fiber communication. The optical fiber splicing tray is mainly used to accommodate and protect the optical fiber splicing points. It is usually made of high-quality plastic or metal materials and has multiple card slots or wire grooves to fix and arrange the optical fibers. Optical cable splicing is the entire operation process of connecting the end of one optical cable to the beginning of the next optical cable to form a continuous optical cable line. The connection point defining the optical cable splicing is called an optical cable joint, which has a great impact on the transmission quality and maintenance cost.
[0003] In vocational education and training, the optical cable splicing tray is often used in the teaching of optical cable splicing. The existing splicing tray has a base and an arc-shaped pressing piece, which is fixed on both sides of the pressing piece by screws to press the optical cable; however, when the splicing tray is used for teaching, the disassembly is relatively frequent. Long-term disassembly and assembly of the screws cause the base made of plastic material to have a thread stripping phenomenon, or the screws may be lost when the screws need to be completely unscrewed during the operation, resulting in relatively large losses and unable to ensure the teaching of optical cable splicing.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0033] Please refer to Figures 1-8, in the embodiment of the present utility model, an optical cable splicing tray for training teaching includes a bottom plate 1, and an installation plate 2 is respectively fixed above both ends of the bottom plate 1; a plurality of cable fixing components 3 are installed on the installation plate 2, and each cable fixing component 3 corresponds to a clamping component 4;
[0034] A steel wire disc 5 is provided between the two installation plates 2;
[0035] The cable fixing component 3 includes a base 31, and an upper fixing piece 32 is fixed above the base 31; a screw rod 34 is threadedly connected to the middle position of the upper fixing piece 32, and a pressing piece 33 is movably connected to the lower end of the screw rod 34.
[0036] By adopting the above technical solution, when fixing the cable, first rotate the screw rod 34 counterclockwise. The screw rod 34 converts the rotational motion into a linear motion and drives the pressing piece 33 to move upward, increasing the opening degree between the pressing piece 33 and the base 31; then pass the cable through the space between the pressing piece 33 and the base 31, and then rotate the screw rod 34 clockwise, so that the pressing piece 33 presses the cable on the base 31, thus completing the clamping and fixing of the cable;
[0037] In this embodiment, through holes are opened at both ends of the pressing piece 33, screws are provided in the through holes, and the screws are threadedly connected to the base 31.
[0038] The two ends of the upper fixing piece 32 are fixed to the base 31 by screws, and the screws at both ends of the upper fixing piece 32 are not disassembled after being fixed, so the screw holes in the base 31 will not be stripped; there will be no thread slipping between the upper fixing piece 32 made of metal and the screw rod 34, which is applicable to frequent teaching operations.
[0039] In this embodiment, the steel wire disc 5 is fixed above the bottom plate 1 by screws, and two convex blocks 6 for facilitating the winding of the steel wire are provided inside the steel wire disc 5.
[0040] By adopting the above technical solution, the setting of the convex blocks 6 facilitates the winding of the steel wire.
[0041] An arc-shaped groove for facilitating the pressing of the optical cable is opened at the middle position of the top of the base 31.
[0042] In this embodiment, the clamping component 4 includes a fixed outer cylinder 41, a fixed disc 44 is fixed at the upper position inside the fixed outer cylinder 41, and a pressing member 43 is slidably connected to the fixed disc 44;
[0043] A semi-circular groove is provided on the surface of the pressing member 43 in contact with the fixed disk 44, and a semi-circular groove is provided on the upper surface of the fixed disk 44; an arc-shaped groove 46 is provided on the surface of the pressing member 43 facing the bottom of the fixed disk 44; a stop groove 47 is penetrated through the fixed outer cylinder 41. A wire passing hole 48 is penetrated through the fixed outer cylinder 41, and the center of the wire passing hole 48 coincides with the center of the semi-circular groove provided on the upper surface of the fixed disk 44.
[0044] By adopting the above technical solution, when fixing the steel wire, first pass the steel wire through the wire passing hole 48 into the space between the pressing member 43 and the fixed disk 44, and then press down the pressing cap 42. At this time, the pressing member 43 presses the steel wire on the fixed disk 44;
[0045] While the pressing member 43 moves downward, the arc-shaped groove 46 at the lower end of the pressing member 43 is aligned with the stop groove 47. Then, an operator inserts a pin shaft into the arc-shaped groove 46 and the stop groove 47, thus realizing the relative fixation of the pressing member 43 and firmly fixing the steel wire;
[0046] With the above structure, the use of screws is not required, and the steel wire can be well clamped and fixed, so that the problem of wire slipping due to the use of screws will not occur.
[0047] In this embodiment, a spring 45 is further provided between the pressing member 43 and the fixed disk 44, and both ends of the spring 45 are embedded in the circular grooves provided on the pressing member 43 and the fixed disk 44.
[0048] By adopting the above technical solution, when the pin shaft is taken out from the arc-shaped groove 46 and the stop groove 47, under the pushing of the elastic force of the spring 45, the pressing member 43 and the fixed disk 44 are separated, and at this time, the steel wire can be taken out. The structure is simple and the operation is very convenient.
[0049] In this embodiment, a D-shaped through groove is penetrated through one side of the fixed disk 44; the pressing member 43 is slidably connected in the D-shaped through groove; a pressing cap 42 is further fixed on the top of the pressing member 43.
[0050] By adopting the above technical solution, the above setting enables the pressing member 43 to be slidably connected in the fixed disk 44, thus facilitating the operation when clamping the steel wire.
[0051] The working principle of the present utility model is as follows: When fixing a cable, first rotate the screw rod 34 counterclockwise. The screw rod 34 converts the rotational motion into a linear motion and drives the pressing piece 33 to move upward, increasing the opening degree between the pressing piece 33 and the base 31. Then, pass the cable through the space between the pressing piece 33 and the base 31. Subsequently, rotate the screw rod 34 clockwise so that the pressing piece 33 presses the cable against the base 31, thus completing the clamping and fixing of the cable. The two ends of the upper fixing piece 32 are fixed to the base 31 by screws. After the screws at both ends of the upper fixing piece 32 are fixed, they are not disassembled anymore, so it will not cause the screw holes in the base 31 to become stripped. There will be no slipping phenomenon between the upper fixing piece 32 made of metal and the screw rod 34, which is applicable to frequent teaching operations.
[0052] When fixing a steel wire, first pass the steel wire through the wire threading hole 48 into the space between the pressing member 43 and the fixing disk 44. Then, press down the pressing cap 42. At this time, the pressing member 43 presses the steel wire against the fixing disk 44.
[0053] While the pressing member 43 moves downward, the arc-shaped groove 46 at the lower end of the pressing member 43 aligns with the stop groove 47. Then, the operator inserts a pin into the arc-shaped groove 46 and the stop groove 47, realizing the relative fixation of the pressing member 43 and firmly fixing the steel wire.
[0054] When the pin is taken out from the arc-shaped groove 46 and the stop groove 47, under the pushing force of the spring 45, the pressing member 43 and the fixing disk 44 are separated. At this time, the steel wire can be taken out. The structure is simple and the operation is very convenient.
