Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the adhesive-free optical cable junction box includes a box base 1 and a box cover 2 that snap together. The box base 1 and the box cover 2 are rotatably assembled on one side, and a locking bolt 3 is provided between the box base 1 and the box cover 2. The box base 1 and the box cover 2 are respectively provided with flanges on their periphery to widen them, thereby improving the firmness of their closed connection and facilitating the installation of sealing facilities. The locking bolt 3 passes through the flanges on the box base 1 and the box cover 2. Reinforcing ribs 4 can also be provided between the box base 1, the box cover 2, and the corresponding flanges, and these reinforcing ribs 4 can be provided both inside and outside the box to improve the overall strength of the box.

[0019] In this embodiment, a silicone sealing strip 5 is fixedly arranged around the open end of the bottom 1 of the box, and a sealing strip 6 that works in conjunction with the silicone sealing strip 5 is arranged around the open end of the cover 2 of the box, with the sealing strip 6 protruding from the surface of the cover 2. After the bottom 1 of the box and the cover 2 of the box are fastened together, the sealing strip 6 is pressed against the silicone sealing strip 5, so that the deformable characteristics of the silicone sealing strip 5 can be used to cover both sides of the sealing strip 6, thereby sealing the optical cable junction box and preventing the ingress of external dust and rainwater.

[0020] like Figure 3 As shown, the sealing strip 6 can be configured as two strips, forming a gap 7 between them. When the silicone sealing strip 5 is pressed, it deforms and partially enters the gap 7, thus forming multiple sealing lines to improve the sealing effect. When the box bottom 1 and the box cover 2 are opened and separated, the silicone sealing strip 5 automatically returns to a flat state due to its self-recovery characteristic, so that when the box bottom 1 and the box cover 2 are fastened again, it can cover and seal the edge of the sealing strip 6. An annular groove can be provided on the box bottom 1, and the silicone sealing strip 5 can be placed in the annular groove to accommodate the protrusion of the sealing strip 6, so that the fastening surfaces of the box bottom 1 and the box cover 2 can be in close contact.

[0021] The bottom of the box 1 has a recessed bottom plug groove 8 at its open end, and the top of the box 2 has a matching top plug groove 9 at its open end corresponding to the bottom plug groove 8. When the bottom of the box 1 and the top of the box 2 are fastened together, the corresponding bottom plug groove 8 and the top plug groove 9 form a cylindrical through hole. Silicone sealing sheets 10 are fixed to the surface of the bottom of the box 1 where the bottom plug groove 8 is located and to the surface of the top of the box 2 where the top plug groove 9 is located. The silicone sealing sheets 10 extend and are laid on the groove walls of the bottom plug groove 8 and the top plug groove 9, respectively. A fiber optic cable plug is detachably installed in the bottom plug groove 8, and the two silicone sealing sheets 10 can tightly cover the outer periphery of the fiber optic cable plug, achieving a seal at the fiber optic cable plug. When connecting the optical cable, the corresponding optical cable plug is removed, allowing the optical cable to pass through into the box. At this time, the silicone sealing sheet 10 can tightly cover the outer periphery of the optical cable, achieving a seal at the point where the optical cable passes through, and completely blocking dust, rainwater, etc. from entering the box.

[0022] The optical cable plugs in this embodiment include a standard optical cable plug 11 and a drop optical cable plug 12. The bottom plug groove 8 and the top plug groove 9, when combined, match the corresponding standard optical cable plug 11 or drop optical cable plug 12. Furthermore, the outer end face of the standard optical cable plug 11 is provided with an optical cable type identifier 13, such as the Arabic numerals "16" or "13". "16" indicates that a 16-core optical cable is used here, and "13" indicates that a 13-core optical cable is used here. Of course, other Arabic numerals can be used depending on the actual usage to distinguish the standard optical cable plug 11, facilitating quick optical cable connection and positioning.

[0023] The bottom of the box 1 is provided with layered splice trays 14. Adjacent splice trays 14 are rotatably assembled, and the splice tray 14 at the lowest layer is fixedly connected to the bottom of the box 1, so as to realize the installation of each layer of splice trays 14 in the bottom of the box 1. The layered arrangement of the splice trays 14 greatly increases the capacity of the optical cable junction box. Between the bottom plug groove 8 and the splice trays 14, there are also ordinary optical cable fixing seats 15, drop optical cable clamps 16 and reinforcing core fixing seats 17. The ordinary optical cable fixing seats 15 are used to fix the introduced ordinary optical cable, the drop optical cable clamps 16 are used to fix the led-out drop optical cable, and the reinforcing core fixing seats 17 are used to fix the reinforcing core of the optical cable.

[0024] The fusion splice tray 14 includes a tray body 141. Several fusion splice grooves 142 are fixed on the surface of the tray body 141. The tray body 141 has two fiber passage ports 143, one for introducing optical fibers and the other for leading out optical fibers. Fiber baffles 144 extending towards the fusion splice grooves 142 are arranged around the periphery of the tray body 141 to limit the optical fibers coiled within the tray body 141, preventing them from being pulled when the upper fusion splice trays 14 move. This helps maintain the neatness of the optical fibers within the tray body 141 and avoids splice point separation due to pulling. A tray body rotation assembly device is provided on the side wall of the tray body 141, allowing all fusion splice trays 14 except the bottommost one to be rotated for easy fiber splicing or inspection and maintenance.

[0025] like Figure 2 and Figure 4As shown, the disc rotation assembly device includes two opposing rotating assembly ears 145 fixedly connected to the disc body 141. Assembly shafts 146 are fixedly attached to the opposing surfaces of the two rotating assembly ears 145. A rotating assembly hook 147 is fixedly connected to each rotating assembly ear 145 directly above the assembly shaft 146, and the rotating assembly hooks 147 are gradually separated from the rotating assembly ears 145 from the inside out. In use, the assembly shaft 146 on the upper welding disc 14 and the rotating assembly hook 147 on the lower welding disc 14 rotate and assemble, realizing the rotational assembly of adjacent welding discs 14.

[0026] In this embodiment, a fiber fixing device is also provided around the splice tray 14 inside the box bottom 1. This device is used to limit and fix the spliced ​​optical fibers, maintaining the neatness of the wiring inside the box and making the fiber routing clear for easy inspection and maintenance. Specifically, the fiber fixing device includes a fiber fixing base 18 fixed to the bottom wall of the box bottom 1. The fiber fixing base 18 is provided with an elastic open ring 19, and the two ends of the elastic open ring 19 are staggered and abutted at the opening. When fixing the optical fiber, the optical fiber is pushed into the elastic open ring 19 through the opening, and the elasticity of the elastic open ring 19 automatically closes the opening with its staggered ends, realizing the circumferential limiting of the optical fiber. The elastic open ring 19 can be configured with an elastic metal sheet or a non-metal sheet, etc.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the utility model, and to enable those skilled in the art to understand the utility model and design various embodiments with various modifications suitable for a particular purpose.
