[0026] Box body 1 side is also equipped with outlet 24, when using, incoming optical fiber enters into box body 1 from wire inlet hole, then appears optical fiber and goes out from outlet 24, in order to prevent outgoing optical fiber from being pulled, multiple support plates 15 are equipped at the side of outlet 24, support plate 15 bottom is connected with the bottom surface of box body 1, second slot 14 is formed on each support plate 15, and the second slot 14 is used to place outgoing optical fiber, as Figure 6 Indicated, outgoing optical fiber can be in a strand or multiple strands, and then the formed strand is placed at support plate 15, and then it can be fixed by binding on second slot 14 with ribbon.

[0027] Further, as shown in Figure 1 and Figure 2 The mounting plate 10 is located in the middle of the bottom surface of the box body 1, and the mounting plate 10 is fastened to the bottom of the box body 1 by screws. A rectangular seat 12 is arranged on the top surface of the mounting plate 10, and a plurality of grooves 13 are arranged on the top of the rectangular seat 12. The grooves 13 are dovetail grooves or T-shaped grooves, and the edges of the rectangular seat 12 are arranged in steps with the edges of the mounting plate 10.

[0028] The present application also includes a plurality of supports 19, the number of which corresponds to the number of fiber cores, that is, the number of light paths. Each support 19 is provided with a first sliding block 20 that is slidably arranged in the groove 13. The first sliding block 20 corresponds to the groove 13 and is a dovetail block or a T-shaped block. The support 19 can move along the groove 13 by the first sliding block 20 to adjust the position of the support 19 on the rectangular seat 12. A fastening screw is arranged on each first sliding block 20. When the position of the support 19 is adjusted, the fastening screw can be used for positioning.

[0029] Each support 19 is provided with a mounting seat 2, and an adapter 17 is detachably arranged in the mounting seat 2. The mounting seat 2 is provided with a cavity that matches the adapter 17. The adapter 17 is actually clamped in the mounting seat 2, which facilitates the installation and removal of the adapter 17.

[0030] A plurality of L-shaped blocks 9 are arranged at the edges of the mounting plate 10, and the top of each L-shaped block 9 extends towards the mounting plate 10. The space surrounded by the L-shaped blocks 9 is used to place the optical fiber (i.e., the tail fiber). It should be noted that the fiber core in the incoming optical fiber needs to be fused with the tail fiber in the box body 1. Since the tail fiber is long, after fusion is completed, the tail fiber can be bent and arranged along the L-shaped blocks 9. The specific bending and arranging condition is shown in Figure 6 Thus, the tail fiber can be placed in the L-shaped blocks 9, thereby avoiding the scattering of the L-shaped blocks 9.

[0031] Further, two stop rods 11 are arranged at one end of the side surface of the rectangular seat 12, and the bottom of the stop rod 11 is connected to the bottom surface of the box body 1.

The fixing seat 5 is provided with at least one second sliding block 21 that is slidably arranged in the groove 13. The second sliding block 21 corresponds to the groove 13 and is a dovetail block or a T-shaped block. The second sliding block 21 is provided with a fastening screw. The fixing seat 5 can move along the groove 13 to change the position, and the fastening screw can be used for fastening when the position is adjusted. Figure 2As shown, the top of the fixed base 5 is provided with two symmetrically arranged limiting baffles 6, which are parallel to the slide groove 13. Limiting rods 23 are detachably connected to the top of the two stop rods 11. The limiting rods 23 are fastened to the stop rods 11 by screws. Limiting plates 16 are detachably provided on the top of the two limiting baffles 6, and the limiting plates 16 are also fastened to the limiting baffles 6 by screws.

[0032] In summary, the specific operational process of this application is as follows:

[0033] 1. First, insert one end of the incoming optical fiber into the inlet hole, then strip the outer sheath of one end of the incoming optical fiber to expose the multiple fiber cores inside the incoming optical fiber, and trim the ends of the fiber cores neatly.

[0034] 2. Fix one end of the incoming optical fiber to the top of the support 8 to prevent the incoming optical fiber from being pulled. Then, fusion splice multiple fiber cores to each pigtail, and cover the fusion splice with a heat-shrink sleeve for protection. Then, attach the pigtail to... Figure 6 The same disc can be fixed inside the L-shaped stop block 9;

[0035] 3. The adapter plug 18 at the end of the pigtail needs to be connected to the adapter 17, so as... Figure 6 As shown, after the pigtail is coiled, the adapter plugs 18 at the ends of each pigtail can be placed between the stop bars 11 to gather the pigtail. Then the pigtail is placed between the two limit plates 6, and both ends of the two limit plates 6 are outwardly flared wide-mouthed. This allows the pigtail to transition along the shape of the limit plates 6, preventing the limit plates 6 from breaking the pigtail.

[0036] 4. Then, the adapter plug 18 at the end of the pigtail can be inserted into the adapter 17. It is important to note that although the pigtails are all coiled along the inner edge of the L-shaped stop 9, the coil lengths of each pigtail differ. Therefore, when the pigtails emerge from between the limiting stops 6, the ends of the pigtails will definitely not be on the same plane, meaning the lengths of the pigtail ends will vary. At this point, the position of the bracket 19 can be adjusted, bringing the adapter 17 closer to the pigtail ends, thus compensating for the uneven lengths of the pigtail ends.

[0037] 5. Finally, install the upper limit plate 16 and the limit rod 23 to limit the pigtail between the two limit baffles 6 and the two stop rods 11, so as to prevent the pigtail from scattering.

[0038] Based on the above embodiments, further optimization can be achieved by providing a baffle 3 on each side of the mounting plate 10, and a first slot 4 is provided on each baffle 3. When coiling the pigtail, the heat shrink sleeves that have been fused together are placed on the side of the baffle 3, and then each heat shrink sleeve is fixed by tying it to the first slot 4 with cable ties. The remaining first slots 4 can also be used to bind the pigtail with cable ties.

[0039] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
