Description

[0002] After the existing arrays are docked, the optical fibers and electric wires are directly coiled in the connector, and there is no auxiliary fiber coiling structure inside. This docking method has a simple structure, but has high requirements for the proficiency of the fiber coiling personnel and the fiber coiling process. Since there are many optical fibers and electric wires in the connector, it is easy to cause the optical fibers to be arranged disorderly and unevenly, which not only has poor aesthetics, but also causes the bending radius of the optical fibers in the box to be too small and the optical fibers to twist with each other, affecting the array loss and subsequent maintenance; the optical fibers and electric wires are placed together, and the optical fibers are easily squeezed by the electric wires and heat shrinkable sleeves, resulting in damage or even breakage of the optical fiber surface; there is no optical fiber fixing structure design, and the optical fibers are easily bounced up or moved, resulting in the optical fibers being clamped off. Content of the Utility Model

Detailed Description of the Invention

[0021] The following further details the specific implementation manners of the present utility model with reference to the drawings, so that those skilled in the art can more clearly understand how to practice the present utility model. Although the present utility model is described in conjunction with its preferred specific implementation manners, these implementation manners are only illustrative and do not limit the scope of the present utility model.

[0022] Specific Embodiment 1: Please refer to Figure 1A storage device inside an optical fiber array docking box, comprising: a backup optical path fiber coiling box 1, a main optical path fiber coiling box 2, a wire storage box 3, a storage box cover 4, a number of buckles 5 and a number of baffles 8. The backup optical path fiber coiling box 1, the main optical path fiber coiling box 2, the wire storage box 3, and the storage box cover 4 are stacked and covered in sequence from bottom to top through the buckles 5. At the same time, the backup optical path fiber coiling box 1 is communicated with the main optical path fiber coiling box 2, and the main optical path fiber coiling box 2 is communicated with the wire storage box 3, which is convenient for completely coiling the optical fiber and the wire inside the storage device after connection, avoiding the situation that the optical fiber and the wire are damaged or even broken on the surface due to exposure; a number of baffles 8 are distributed on the ports of the backup optical path fiber coiling box 1, the main optical path fiber coiling box 2, and the wire storage box 3 to prevent the optical fiber and the wire from bouncing up; this storage device inside the optical fiber array docking box is applied during the docking process of the optical fiber hydrophone array, and has the characteristics of neat and orderly optical fiber storage, effective fixation of heat shrinkable tubes without loosening, reasonable distinction between the main and backup optical paths, and non-interference between wires and optical fibers.

[0023] In this embodiment, the buckle 5 is composed of a plug and a socket that cooperate with each other. The socket is a cylindrical structure, and a plugging groove is opened at the top thereof. During implementation, the plug and the socket are respectively arranged on two relatively independent components and are in corresponding positions. Inserting a part of the plug into the plugging groove and tightly fitting with the socket can realize the fixed connection between the above two relatively independent components. For example, in this embodiment, between the storage box cover 4 and the wire storage box 3, the plug is arranged at the lower end of the storage box cover 4, and the socket is arranged inside the wire storage box 3. The storage box cover 4 and the wire storage box 3 are fixedly connected by plugging; similarly, between the backup optical path fiber coiling box 1 and the main optical path fiber coiling box 2 and between the main optical path fiber coiling box 2 and the wire storage box 3, they are all fixedly connected by plugging through the buckle 5.

[0024] In one embodiment, the structure of the socket is not limited to the above-mentioned cylindrical shape, and can also be a strip or block structure; in addition, the external position of the buckle 5 is not limited to the inside of the storage device body, and can also be on its outside or the edge of the corresponding component.

[0025] As described above, the backup optical path fiber coiling box 1 is used as a storage box for optical fiber backup, and its structure is the same as that of the main optical path fiber coiling box 2. Taking the main optical path fiber coiling box 2 as an example, the main optical path fiber coiling box 2 is a box-shaped structure with an open upper end and two wire outlets 7 opened at both ends. A number of baffles 8 are distributed on the upper port of the main optical path fiber coiling box 2; the backup optical path fiber coiling box 1 is communicated with the main optical path fiber coiling box 2 through the wire outlets 7 at corresponding positions;

[0026] The optical fibers of the array need to be fusion-connected, and an optical fiber heat shrinkable tube 10 is arranged at the fusion connection; a number of limiting plates with mutually parallel main planes are also arranged along the length direction inside the main optical path fiber coiling box 2, and a card slot 9 is formed between two adjacent limiting plates for fixing the optical fiber heat shrinkable tube 10.

[0027] Furthermore, in order to improve the quality of fiber coiling, reduce the fiber breakage rate and meet the requirement of the fiber bending radius within the required range, both ends of the main optical path fiber coiling box 2 in the length direction are semi-circular structures; in other embodiments, the main optical path fiber coiling box 2 can also be a cylindrical structure, and the smooth internal structure can better meet the fiber bending requirements.

[0028] In order to increase the air permeability and heat dissipation performance, through holes are provided on the bottom walls of the backup optical path fiber coiling box 1 and the main optical path fiber coiling box 2.

[0029] The wire storage box 3 is covered on the main optical path fiber coiling box 2, and an outlet 7 is also provided on the bottom wall of the wire storage box 3. The wire storage box 3 is communicated with the main optical path fiber coiling box 2 through the outlet 7.

[0030] In one embodiment, both the backup optical path fiber coiling box 1 and the main optical path fiber coiling box 2 serve as fiber storage devices, and their numbers are not limited to the above two, and the number of fiber storage devices can be increased or decreased according to the specific usage situation.

[0031] The specific implementation of the fiber storage device for the fiber array docking box is as follows:

[0032] 1. Thread the array pigtail into the fiber coiling box through the outlet, and butt-fuse the two ends of the pigtail; the array backup optical path fiber is stored in the backup optical path fiber coiling box, fix the fiber heat shrinkable sleeve in the card slot, and coil the remaining fiber inside the fiber coiling box and place it under the retaining piece to prevent the fiber from bouncing up;

[0033] 2. After the backup optical path fiber coiling is completed, fix the main optical path fiber coiling box on the backup optical path fiber coiling box through the buckle. Thread the array main optical path fiber into the fiber coiling box through the outlet of the main optical path fiber coiling box, and the fiber coiling method is the same as that in step 1;

[0034] 3. Fix the wire storage box on the main optical path fiber coiling box through the buckle, and thread the wire into the wire storage box through the outlet of the wire storage box and place it under the retaining piece to prevent the wire from bouncing up;

[0035] 4. Fix the storage box cover on the wire storage box through the buckle to protect and isolate the wire.

[0036] In summary, by providing a plurality of card slots, baffles and optical fiber accommodating cavities on the fiber winding box, the optical fiber devices and heat shrinkable sleeves are positioned, placed and fixed, and at the same time, the bending radius of the optical fiber in the box is controlled within the required range. This not only improves the orderliness and aesthetics of the placement and fiber winding of the devices in the box, but also reduces the phenomenon of optical fiber damage caused by too small bending radius of the optical fiber, interference between loose devices or optical fibers; in addition, the array backup optical path and the remaining unused optical fibers are wound in the bottom backup optical path fiber winding box, the array main optical path is wound in the main optical path fiber winding box, the wire is wound in the wire storage box, and the top is the storage box cover. This layered structure design meets the requirement that the wires do not squeeze the optical fibers, effectively separates the placement of the optical fibers and wires, and facilitates the disassembly, installation and maintenance after the array docking.
