[0055] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0056] Referring to Figures 1, 2, 3, 4, 5 and 6, an embodiment of the present application provides a miniaturized optical cable junction box, which includes a box body 1, a door panel 2, an internal component 3 and a telescopic assembly 4. The box body 1 is provided with a door panel 2, and the box body 1 is opened and closed by the door panel 2; the telescopic assembly 4 is located on the side wall of the box body 1, and the side wall is adjacent to the door panel 2. One end of the telescopic assembly 4 is fixed to the side wall, and the other end is rotatably connected to the internal component 3, and is used to extend or retract so that the internal component 3 extends from the inside of the box body 1 or returns to the inside of the box body 1.

[0057] In the optical cable junction box provided in the embodiment of the present application, the internal component 3 is rotatably connected to one end of the telescopic component 4, and the other end of the telescopic component 4 is fixed on the inner wall of the box body 1 adjacent to the door panel 2. Since the telescopic component 4 can be extended or retracted, when it is necessary to operate the various functional modules on the internal component 3, the internal component 3 can be dragged outward, and the telescopic component 4 will extend accordingly, so that the internal component 3 extends from the inside of the box body 1, and then the space outside the box body 1 is used for operation; since the internal component 3 is rotatably connected to the telescopic component 4, when it is necessary to operate the functional modules on the side or back of the internal component 3, the internal component 3 can also be rotated to perform the operation; when the operation is completed, the internal component 3 can be rotated back to its original position, and then the internal component 3 can be pushed into the box body 1, and the telescopic component 4 can be retracted, so that the internal component 3 returns to the inside of the box body 1, and finally the door panel 2 is locked.

[0058] It can be seen that the present application designs the push-pull and rotation operations of the internal component 3, so that it can make full use of the external space to achieve the operation purpose of each functional module on the internal component 3. In this way, while ensuring sufficient operating space, the size of the optical cable junction box is reduced, the land resource occupied by the optical cable junction box is reduced, and land resources are saved.

[0059] It is understood that in the present application, the box body 1 has three side walls, one of which is the rear side wall opposite the door panel 2, and the other two parallel and opposite side walls, one is the left side wall and the other is the right side wall. The telescopic assembly 4 can be installed on the left or right wall. Since the door panel 2 is usually installed on the left wall to rotate to the left to open, for more convenient operation and more in line with operating habits, as shown in Figures 1 and 2, the telescopic assembly 4 is installed on the right wall.

[0060] In order to enable the internal component 3 to extend from the inside of the box body 1 or return to the inside of the box body 1, the present application also provides a specific structure of the telescopic assembly 4, as shown in Figures 5 and 6, the telescopic assembly 4 includes a fixed column 5, a movable column 6, a vertical sliding groove 7 and two telescopic arms 8, the fixed column 5 is provided with a vertical sliding groove 7, the movable column 6 is rotatably connected to the internal component 3, and is provided with a vertical sliding groove 7; the two telescopic arms 8 are cross-arranged and rotatably connected, one end of the two telescopic arms 8 is respectively rotatably connected to the fixed column 5 and the movable column 6, and the other end is movably provided in the vertical sliding groove 7 of the fixed column 5 and the movable column 6 through a sliding pin.

[0061] When the internal component 3 is dragged outward, the movable column 6 will move outward accordingly. Due to the presence of the vertical sliding groove 7, the movable column 6 will drive the two telescopic arms 8 to rotate and extend, thereby achieving the purpose of extension. When the internal component 3 is pushed inward, the two telescopic arms 8 will move in the opposite direction and finally retract.

[0062] It can be understood that, with two telescopic arms 8 as a group, multiple groups can be set according to the length of the fixed column 5 and the movable column 6. For example, in Figure 6, two groups of telescopic arms 8 are set to prevent local uneven force from getting stuck, resulting in unsmooth movement.

[0063] The present application adopts the above-mentioned crossed telescopic arms 8 to achieve telescopic movement for at least the following reasons: on the one hand, the structure is simple and efficient, and setting the structure in the originally small box 1 will not occupy too much space in the box 1; on the other hand, multiple sets of telescopic arms 8 can be added according to actual conditions to achieve uniform force and ensure smooth movement.

[0064] It is understandable that in addition to the above-mentioned cross telescopic arm 8 scheme, other schemes can also be adopted, such as installing a driving device such as a cylinder or an oil cylinder on the side wall, and using the telescopic shaft of the cylinder or the oil cylinder to push the moving column 6 to achieve telescopic movement.

[0065] In order to further ensure the smooth movement of the movable column 6, the telescopic assembly 4 provided in the present application also includes a guide mechanism, as shown in Figure 2, the guide mechanism includes a guide member 9 and a horizontal guide groove 10, and the horizontal guide groove 10 can be formed by bending a sheet metal part. The guide member 9 is arranged on the movable column 6, and the horizontal guide groove 10 is arranged on the side wall of the box body 1.

[0066] It is understandable that the above-mentioned guide mechanisms can be provided with two, one above and one below. As shown in FIG2 , a horizontal guide groove 10 is provided above the top of the fixed column 5 , and a horizontal guide groove 10 is also provided below the bottom of the fixed column 5 .

[0067] 2 and 6 , the inner member 3 is also provided with a guide member 9, and when the inner member 3 is extended from the interior of the box body 1, the guide member 9 slides out of the horizontal guide groove 10. The advantage of providing the guide member 9 on the inner member 3 is that, under the guidance and constraint of the horizontal guide groove 10, the inner member 3 can be pushed into the box body 1 more smoothly.

[0068] It is understandable that the guide member 9 may be a bolt or the like. In order to reduce friction, preferably, the guide member 9 is a roller. Rolling friction is relative to sliding friction, and the operator can push and pull with less force, which is more labor-saving and worry-free.

[0069] Referring to Figures 1, 2, 3 and 4, in the present application, the internal component 3 includes a frame rotatably connected to the telescopic assembly 4. When the frame returns to the inside of the box 1, the wall of the frame facing the door panel 2 is sequentially arranged with a splitter module 11, a termination module 12 and a parking module 13 from top to bottom, and a splitter pigtail management module 14 is also provided on the side of the termination module 12; the wall of the frame away from the telescopic assembly 4 is sequentially arranged with a pigtail management module 15, a fusion splicing module 16, an optical fiber management module 17 and an optical fiber fixing module 18 from top to bottom.

[0070] This application also designs a set of fiber routing paths suitable for this layout. Taking the cable entry and exit at the bottom of the box 1 as an example, as shown in Figures 2, 3, and 4, the bottom of the box 1 is installed with several cable sealing modules 30 for the entry and exit of optical cables, and the rear side wall of the box 1 is provided with a fiber routing unit 45.

[0071] The input optical cable enters the box 1 from the cable sealing module 30 at the bottom, and then separates the input optical fiber (marked with label A). After running on the fiber running unit 45 on the rear side wall of the box 1, the input optical fiber A is fixed on the optical fiber fixing module 18, and then enters the fusion splicing module 16 to be fused with the input end pigtail (marked with label C). After the input end pigtail C passes through the pigtail management module 15, it passes through the pigtail inlet and outlet 46 on the pigtail management module 15, runs downward from the back of the pigtail management module 15, and enters the termination module 12. The input end pigtail C is terminated with the splitter input end pigtail (marked with label E) through the termination module 12. The splitter input end pigtail E passes through the front of the termination module 12, goes upward around the splitter pigtail management module 14, and enters the splitter module 11. The optical signal is transmitted to the splitter module 11 through the splitter input end pigtail E and is split.

[0072] After splitting, the pigtail (marked with label F) is output from the splitter output end, and the splitter output end pigtail F comes out from the splitter module 11, passes through the splitter pigtail management module 14, and enters the termination module 12. The splitter output end pigtail F and the output end pigtail (marked with label D) are terminated through the termination module 12. The output end pigtail D comes out from the back of the termination module 12, passes through the pigtail inlet and outlet 46 on the pigtail management module 15, passes through the pigtail management module 15, and is fused with the output optical fiber (marked with label B) on the fusion splicing module 16. After the output optical fiber B is routed on the fiber routing unit 45 on the rear side wall of the box 1, it exits the box 1 from the cable sealing module 30 at the bottom.

[0073] 5 and 6 , in the present application, the telescopic assembly 4 is rotatably connected to the internal component 3 via a rotating shaft 19 ; it is understandable that a plurality of the rotating shafts 19 may be provided.

[0074] In order to improve the anti-theft capability of the transfer box, as shown in Figure 7, in the present application, the box body 1 and the door panel 2 are connected by an embedded hinge 20; in this way, after the door panel 2 is closed, the gap between the door panel 2 and the box body 1 is extremely small. On the one hand, the sealing performance is good to prevent rainwater from entering, and on the other hand, it is difficult to pry open with tools, thereby improving the anti-theft capability.

[0075] Furthermore, as shown in FIG8 , the door panel 2 includes an outer door panel layer and an inner door panel layer that are connected to each other. A door panel reinforcement 21 is provided between the outer door panel layer and the inner door panel layer. The provision of the door panel reinforcement 21 increases the strength of the door panel 2 and thereby enhances the anti-theft capability. It is understood that the door panel reinforcement 21 can be formed by bending sheet metal, and multiple door panel reinforcements 21 may be provided.

[0076] Furthermore, as shown in FIG9 , the box body 1 includes an outer and inner box layer connected to each other. Corner reinforcements 22 are provided between the outer and inner box layers and at the corners of the box body 1. The provision of the corner reinforcements 22 increases the strength of the box body 1 and thereby enhances its anti-theft capabilities. It is understood that the corner reinforcements 22 can be formed by bending sheet metal, and multiple corner reinforcements 22 may be provided.

[0077] Further, referring to Figure 1, a lock rod guide seat 23 is provided on the inner wall of the door panel 2, and a lock rod 25 of the anti-theft lock 24 installed on the door panel 2 vertically passes through the lock rod guide hole of the lock rod guide seat 23, and a lock rod pin hole 26 compatible with the lock rod 25 is provided in the box body 1; since the lock rod 25 is long, the bending resistance of the lock rod 25 can be enhanced by providing the lock rod guide seat 23 and the lock rod pin hole 26. When the door panel 2 is pulled outward with force, since one end of the lock rod 25 passes through the lock rod guide seat 23 and the lock rod pin hole 26, and the other end is connected to the anti-theft lock 24, when the door panel 2 is pulled outward, the lock rod 25 is subjected to force at the lock rod guide seat 23, the lock rod pin hole 26 and the anti-theft lock 24, so that the lock rod 25 is not easy to bend and cause the door panel 2 to open, thereby improving the anti-theft ability of the transfer box.

[0078] As can be seen in Figure 1, there are two locking rods 25, one above the other. Each locking rod 25 is equipped with a locking rod guide seat 23. The locking rod pin hole 26 of the lower locking rod 25 is located at the bottom of the box body 1. As shown in Figure 10, the locking rod pin hole 26 of the upper locking rod 25 is located at the top of the box body 1. When tightening the anti-theft lock 24, the two locking rods 25 are moved closer together to unlock, thereby opening the door panel 2, or moved away from each other to insert into the corresponding locking rod pin hole 26 to achieve locking.

[0079] Furthermore, referring to Figure 1, an operating platform 27 is rotatably provided on the inner wall of the door panel 2, and a support platform 28 is also provided on the inner wall of the door panel 2 below the operating platform 27. A support rod 29 is rotatably connected to the operating platform 27, and when the support rod 29 rotates to support the support platform 28, the operating platform 27 is in a horizontal state.

[0080] When the operating table 27 is folded up, the support rod 29 can be placed against the back of the operating table 27 . In order to fix the support rod 29 , a bayonet 47 is provided on the back of the operating table 27 , and the support rod 29 can be snapped into the bayonet 47 .

[0081] Furthermore, as shown in FIG1 , the bottom of the box 1 is provided with a plurality of cable sealing modules 30 for the entry and exit of optical cables. It can be seen that the present application can allow the entry and exit of optical cables from the top or the bottom, and the choice can be flexible according to the actual installation site.

[0082] 1 , 2 , 11 , 12 and 13 , the box body 1 has an open top cover 32 , and a cable sealing module 30 for the entry and exit of optical cables is installed on the opening 31 provided on the open top cover 32 , thereby achieving the purpose of entry and exit of optical cables from the top.

[0083] It is understandable that the opening top cover 32 can be detachably mounted on the top of the box body 1 by screws or the like.

[0084] If there is no need for cables to enter or exit the top of the box body 1, the sealing problem of the opening 31 is involved. This application exemplarily provides two solutions. For example, as an example, in one solution, as shown in FIG14 , the box body 1 is configured with a closed top cover 34. The closed top cover 34 and the open top cover 32 are selectively installed on the top of the box body 1. If cables need to enter or exit the top, the open top cover 32 is selected to be installed on the top of the box body 1. If cables do not need to enter or exit the top, the closed top cover 34 is replaced. For another example, as an example, in another solution, as shown in FIG12 , the open top cover 32 is configured with a blind hole sealing module 33. The blind hole sealing module 33 is installed on the opening 31 to achieve sealing of the opening 31.

[0085] Due to the complex arrangement of optical cables on site, it may be necessary to replace the position of the incoming and outgoing cables at the top. Therefore, in order to arrange the optical cables more flexibly, the present application exemplarily provides two solutions for replacing the position of the opening 31. For example, as an example, in one scheme, referring to Figures 12 and 13, openings 31 are provided on both sides of the open top cover 32 of the box body 1, and a cable sealing module 30 is installed on one of the openings 31, and a blind hole sealing module 33 is installed on the other opening 31. According to actual conditions, the positions of the cable sealing module 30 and the blind hole sealing module 33 can be replaced, thereby realizing the replacement of the position of the opening 31 for cables to enter and exit. For another example, as an example, in another scheme, referring to Figure 11, the open top cover 32 of the box body 1 has two mutually perpendicular axes of symmetry, one of which is the midpoint line of the two wide sides of the open top cover 32, and the other is the midpoint line of the two long sides of the open top cover 32, and there is one opening 31, which is located on one of the two sides of the open top cover 32 of the box body 1. In this scheme, the open top cover 32 is a symmetrical structure, one side of which is provided with an opening 31, and the position of the opening 31 can be replaced by rotating the open top cover 32.

[0086] In addition, the closed top cover 34 and the open top cover 32 can be designed to be inclined to facilitate rainwater to slide off.

[0087] The closed top cover 34 and the open top cover 32 are designed with screw holes near the side of the door panel 2. The closed top cover 34 and the open top cover 32 can be disassembled and assembled only after the door is opened, which has better anti-theft performance.

[0088] Furthermore, as shown in FIG. 15 , a top shielding cover 35 for shielding the cable sealing module 30 is provided on the opening top cover.

[0089] In the present application, there are at least two installation schemes for the box 1. For example, as an example, a floor-mounted installation method can be adopted. Specifically, referring to FIG. 1 , a floor-mounted installation base 36 is provided at the bottom of the box 1 .

[0090] For another example, a pole installation method can be adopted. Specifically, as shown in FIG15 , a pole installation component 37 for installation on a pole is provided on the side wall of the box body 1 .
