Description

Technical Field

[0001] The utility model relates to the technical field of optical cable installation, in particular to an outdoor optical cable junction box. Background Art

[0002] Optical cable is manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. Since the optical fiber itself is long, it is inevitable that extra optical fiber will be left during installation, and the extra length of optical fiber stored in the junction box will inevitably be entangled with each other, causing damage to the optical fiber. This requires the use of an outdoor optical cable junction box, so the existing outdoor optical cable junction box has been continuously innovated and developed. Therefore, it can be seen that the current outdoor optical cable junction box basically meets people's needs, but there are still some problems.

[0003] For example, the patent document with the announcement number CN214409402U discloses an outdoor optical cable junction box, including a first box body, the first box body is provided with a second box body, the second box body is provided with an L-shaped connecting plate, and a locking mechanism is provided between the second box body and the first box body; the locking mechanism includes a locking block, a spring, a movable block, a pull rope, an inner handle and an outer handle, the second box body is provided with a step cavity, the locking block is arranged in the step cavity, the spring is located between the locking block and the step cavity, the first box body is provided with a lock hole, the L-shaped connecting plate is provided with a movable groove, and the movable block is arranged in the movable groove Inside, one end of the pull rope is connected to the locking block, and the other end of the pull rope is connected to the movable block. The second box body is provided with a pull rope groove, the inner handle is arranged on the rear side of the movable block, and the outer handle is arranged on the L-shaped connecting plate. When the optical cable junction box needs to be expanded, the first box body and the second box body can be staggered with each other to adjust the use space size of the optical cable junction box. It is convenient to use and has high practicality. By arranging the L-shaped connecting plate, the first box body and the second box body can be staggered with each other to adjust the use space size of the optical cable junction box. It is convenient to use and has high practicality.

[0004] However, when the above device expands the use space of the box, it is inevitable that the number of optical fibers in the box will increase. When the optical fibers are connected, there will be too long optical fibers. Due to the excessive number of optical fibers in the box, multiple groups of too long optical fibers will inevitably be entangled with each other, thereby causing damage to the optical fibers. Therefore, an outdoor optical cable junction box is urgently needed to solve the above problem. Utility Model Content

[0005] The utility model aims to provide an outdoor optical cable junction box to solve the problem in the above background technology that overlong optical fibers are inevitably entangled with each other, thus causing damage to the optical fibers.

[0014] As a preferred technical solution of the utility model, the wire groove is Z-shaped, the wire groove runs through the inner wall of the box, and the opening of the wire groove located on the inner wall of the box is higher than the opening of the outer wall of the box.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] 1. The utility model connects two groups of optical fibers by inserting the optical fibers through the wire trough into the slots. After the optical fibers are connected, the excess length of the optical fibers is coiled, and the second limiting plate is pushed to open the gap between the first limiting plate and the second limiting plate, and the center of the rolled optical fiber is overlapped to the surface of the second limiting plate, and then the second limiting plate is loosened to close the first limiting plate and the limiting plate to store the rolled optical fiber. This not only improves the cleanliness inside the box, omits the subsequent step of combing the optical fibers, thereby facilitating the installation of the optical fibers by the staff, but also reduces the probability of the optical fibers being entangled with each other when the equipment is in use, thereby avoiding damage to the optical fibers.

[0017] 2. The utility model passes the optical fiber through the cable trough, and the springs on both sides of the cable trough push the clamping block, so that the rubber pad on one side of the clamping block fits the surface of the optical fiber, thereby clamping the optical fiber. The rubber pad not only avoids the situation where the clamping block causes crushing damage to the optical fiber, but also reduces the distance between the optical fiber and the inner wall of the cable trough, preventing insects from entering the box through the cable trough and building nests in the box or damaging the structure inside the box, thereby extending the service life of the equipment.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1 , Figure 5 and Figure 6 An outdoor optical cable junction box: comprising a box body 1, the inner walls of both sides of the box body 1 are provided with wire grooves 2, a partition 3 is fixedly connected to the middle of the inner wall of the box body 1, and a slot 4 is provided on the inner wall of the partition 3;

[0029] The winding assembly includes a first limit plate 5, the inner wall of the box body 1 is fixedly connected to the first limit plate 5, the inner wall of the box body 1 is provided with a movable groove 6, the inner wall of the movable groove 6 is slidably connected to a movable block 7, one side of the movable block 7 is fixedly connected to a second limit plate 8, one side of the movable block 7 is provided with a first spring 9, and one end of the first spring 9 is provided on the inner wall of the movable groove 6.

[0030] In an outdoor optical cable junction box, two groups of optical fibers are first distributed through the wire grooves 2 on both sides of the box body 1, the joint part of the optical fiber is inserted into the box body 1, and then the joint of the optical fiber is inserted into the slot 4, so as to dock the two groups of optical fibers, and then the optical fiber is pulled. Since the optical fiber is long, when the optical fiber is pulled, the excess part of the optical fiber is pulled into the box body 1 through the wire groove 2, and then the excess optical fiber is wound into a roll, and the second limit plate 8 is pushed, so that the extended movable block 7 of the second limit plate 8 slides in the movable groove 6, so that the second limit plate 8 moves relatively, and the second limit plate 8 After the movement, a gap is formed between the second limiting plate 8 and the first limiting plate 5, and then the rolled optical fiber is placed between the second limiting plate 8 and the first limiting plate 5, and then the second limiting plate 8 is released, and the movable block 7 is pushed to move by the first spring 9. The movement of the movable block 7 then drives the second limiting plate 8 to move. After the second limiting plate 8 moves, one side of it is attached to the first limiting plate 5, thereby closing the opened gap. After the first limiting plate 5 and the second limiting plate 8 are closed, the rolled optical fiber is retracted between the first limiting plate 5 and the second limiting plate 8.

[0031] See also Figure 4 and Figure 8 A second spring 10 is arranged on both sides of the inner wall of the wire groove 2, a clamping block 11 is arranged at one end of the second spring 10, a first rubber pad 12 is arranged on one side of the clamping block 11, and a groove 13 is opened on the top of the first rubber pad 12.

[0032] When the optical fiber passes through the wire groove 2 from the opening in the box body 1, the optical fiber is first released to the groove 13. Since the opening of the groove 13 gradually becomes smaller from top to bottom, the optical fiber encounters less resistance when passing through the clamping block 11. After passing through the wire groove 2, the clamping block 11 is relatively moved by the small elastic force of the second springs 10 on both sides, so that the first rubber pad 12 on one side of the clamping block 11 can fit the surface of the optical fiber.

[0033] See also Figure 2 , Figure 4 and Figure 7 The top and bottom of the inner wall of the slot 4 are fixedly connected with a card block 14, the surface of the card block 14 is fixedly connected with a second rubber pad 15, the back of the box body 1 is fixedly connected with a mounting plate 18, and threaded grooves 19 are opened on both sides of the front of the mounting plate 18.

[0034] Before using an outdoor optical cable junction box, first use bolts to fix the mounting plate 18 to the wall through the threaded groove 19. After the mounting plate 18 is fixed, the front box body 1 is fixed, and the clamp block 14 can clamp and fix the structure of the optical fiber connector part.

A sealing gasket 20 is fixedly connected to the top of the front of the box body 1, and one side of the sealing gasket 20 is overlapped on the back of the door 16. The wire groove 2 is Z-shaped, and the wire groove 2 runs through the inner wall of the box body 1. The opening of the wire groove 2 located on the inner wall of the box body 1 is higher than the opening of the outer wall of the box body 1.

[0036] The lock body 17 usually needs to be opened with a specific key. The Z-shaped wire groove 2 can prevent rainwater from entering the box body 1, and the sealing gasket 20 can prevent rainwater from penetrating into the box body 1.

[0037] Working principle: when using an outdoor optical cable junction box, first insert two groups of optical fibers into the box 1 through the wire grooves 2 on both sides of the box 1, and then insert the joint of the optical fiber into the slot 4, so that the block 14 clamps and fixes the structure at the optical fiber joint, thereby connecting the two groups of optical fibers, and then coil the excess length of the optical fiber into a roll, and then push the second limit plate 8 to open the gap between the first limit plate 5 and the second limit plate 8, place the rolled optical fiber on the surface of the second limit plate 8, loosen the second limit plate 8, and let the first spring 9 push the second limit plate 8 to reset, thereby fixing the rolled optical fiber between the first limit plate 5 and the second limit plate 8, and storing the excess length of the optical fiber.
