After installation, the numerous and long pigtails are prone to getting messy, resulting in troublesome wiring and inconvenience for subsequent maintenance. In addition, the long pigtails need to be wound inside the installation box.

[0030] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the protection scope of the present utility model.

[0031] Please refer to the attached Figures 1-5, the planar optical waveguide optical splitter in the embodiment of the present utility model includes a housing 1, which is used for protection. The housing 1 is made of aluminum alloy, with light weight, high strength, and good protection ability. On one side inside the housing 1, an optical splitter main body 3 is fixed. The optical splitter main body 3 is connected with a plurality of pigtails 4. At the front end inside the housing 1, a wire clamping mechanism 6 is fixed. On the other side inside the housing 1, a multi-layer wire distributing disk 5 is fixed, and a plurality of pigtails 4 are all wound around the multi-layer wire distributing disk 5.

[0032] The provided wire clamping mechanism 6 is used to separate and fix the pigtails 4, thereby preventing the pigtails 4 from being scattered. The provided multi-layer wire distributing disk 5 is used to wind the pigtails 4 in layers. Compared with the way of winding all the pigtails 4 together, when disassembling a single pigtail 4, the corresponding pigtail can be separated more quickly, further improving the subsequent maintenance efficiency.

[0033] The wire clamping mechanism 6 includes a housing 61. On the upper end surface of the housing 61, a plurality of notches 62 are evenly spaced. Inside each of the plurality of notches 62, a wire clamp 63 is fixed. The number of notches 62 is the same as the number of pigtails 4, and one pigtail 4 corresponds to a corresponding notch 62, thereby separating the pigtails 4.

[0034] The wire clamp 63 includes a fixed seat 631 fixedly connected to the housing 61. Above the fixed seat 631, a movable table 632 is provided. Between the fixed seat 631 and the movable table 632, a locking assembly 634 is provided. On both sides of the movable table 632, clamping assemblies 633 are provided.

[0035] The clamping assembly 633 includes a rotating shaft 6331 rotatably connected to the housing 61. On both outer ends of the rotating shaft 6331, clamping claws 6333 are fixed. In the middle of the rotating shaft 6331, a gear 6332 is fixedly sleeved.

[0036] The clamping assembly 633 further includes a rack 6334. The rack 6334 is fixedly connected to the lower end of the movable table 632. The gear 6332 is meshed with the rack 6334.

[0037] When installing the pigtail 4, the pigtail 4 is passed through the corresponding notch 62, and then the pigtail 4 is pressed downward. The pigtail 4 contacts the movable table 632, and the movable table 632 moves downward under the force. Since the rack 6334 is fixedly connected to the movable table 632, the rack 6334 also moves downward together with the movable table 632, thereby driving the gear 6332 to rotate. As the gear 6332 rotates, the upper ends of the clamping claws 6333 on both sides approach each other, thereby clamping the pigtail 4.

[0038] The locking assembly 634 includes a running pin 6341 and a maze cavity 6342. The lower end of the running pin 6341 is rotatably connected to the fixed seat 631. The maze cavity 6342 is opened at the outer end of the movable table 632. The upper end of the running pin 6341 is slidably connected to the maze cavity 6342.

[0039] The locking component 634 further includes a spring rod 6343. The upper and lower ends of the spring rod 6343 are respectively fixedly connected to the fixed seat 631 and the movable table 632. The provided spring rod 6343 is used to provide elastic force so that the movable table 632 can rebound to a high position after being pressed down.

[0040] When clamping the optical fiber pigtail 4, the movable table 632 moves downward, and the needle 6341 slides along one side of the maze cavity 6342 until it slides to the concave part at the upper end of the maze cavity 6342. At this time, stop pressing down the movable table 632, and the needle 6341 is limited at the concave part at the upper end of the maze cavity 6342, thereby locking the movable table 632. When unlocking is required, the movable table 632 can be pressed down again, and the needle 6341 slides along the other side of the maze cavity 6342, slides out of the concave part at the upper end of the maze cavity 6342, and until it slides to the lower end of the maze cavity 6342, the movable table 632 moves to a high position through the elastic force of the spring rod 6343, and the clamping jaws 6333 on both sides are separated, thereby unlocking the optical fiber pigtail 4.

[0041] The multi-layer distribution disc 5 includes a disc body 51. A plurality of wire grooves 52 are evenly spaced at the outer end of the disc body 51. A plurality of optical fiber pigtails 4 are respectively wound around different wire grooves 52. The inside of the disc body 51 is hollow, and the inner walls of the plurality of wire grooves 52 are all arc-shaped.

[0042] A plurality of optical fiber pigtails 4 can be wound around each wire groove 52 in layers, so that only a small number of optical fiber pigtails 4 are accommodated in one layer of wire grooves 52. Compared with the way that all the optical fiber pigtails 4 are wound together, when disassembling a single optical fiber pigtail 4, the corresponding optical fiber pigtail 4 can be separated more quickly, further improving the subsequent maintenance efficiency. Among them, the hollow setting inside the disc body 51 can reduce the weight of the disc body 51, which is convenient for installation, and the arc-shaped wire grooves 52 are more in line with the cylindrical shape of the optical fiber pigtail 4, and the stability after winding is good.

[0043] A plurality of interfaces 2 are fixed to the outer end of the housing 1. The end parts of a plurality of optical fiber pigtails 4 are respectively connected to the plurality of interfaces 2. The parts of the plurality of optical fiber pigtails 4 close to the interfaces 2 all pass through the wire clamps 63. The optical fiber pigtails 4 and the wire clamps 63 are in one-to-one correspondence, and each wire clamp 63 is independently arranged and can be used separately, so that each optical fiber pigtail 4 can be disassembled separately without affecting the use of other optical fiber pigtails 4.

[0044] Working principle: During use, the multi-layer wire dividing disc 5 and the wire clamping mechanism 6 are respectively fixed inside the housing 1. First, the optical splitter body 3 is fixedly installed inside the housing 1. Then, the respective pigtails 4 of the optical splitter body 3 are coiled in the respective wire receiving grooves 52 of the multi-layer wire dividing disc 5, so that only a small number of pigtails 4 are received in one layer of the wire receiving groove 52, which is convenient for separating a single pigtail 4. After the coiling is completed, the pigtail 4 is connected to the corresponding interface 2. After the connection is completed, the pigtail 4 is separated and fixed by the wire clamping mechanism 6. When fixing, the pigtail 4 passes through the corresponding wire clamp 63 in sequence, and then the pigtail 4 is driven to be pressed downward. The movable table 632 of the wire clamp 63 moves downward under force, and drives the upper ends of the clamping jaws 6333 on both sides to approach each other through the transmission of the rack 6334 and the gear 6332, so as to clamp the pigtail 4. When it is necessary to take out the pigtail 4, the part where the pigtail 4 contacts the wire clamp 63 can be pressed again, and the locking assembly 634 is unlocked. The movable table 632 moves upward under the elastic force of the spring rod 6343, and drives the clamping jaws 6333 on both sides to separate through the transmission of the rack 6334 and the gear 6332, so that the pigtail 4 is unlocked.

[0045] The above has described an embodiment of the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as used to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
