Description

Technical Field

[0001] This utility model belongs to the field of optical cable joint technology, and in particular relates to an optical cable joint pressure protection device. Background Technology

[0002] Optical fiber cable is a communication cable that uses light waves as the information carrier and optical fiber as the transmission medium. It is used for long-distance, high-capacity data transmission and is widely used in backbone networks, metropolitan area networks, access networks, and home networks. Optical fiber cables are connected together by connectors. Among them, the home optical fiber cable connector is a key component that connects the operator's optical network terminal (ONT) to the home's internal optical fiber equipment (such as optical fiber routers, ONUs) to realize the signal distribution and transmission after high-speed broadband (gigabit / 10 gigabit) is brought into the home.

[0003] Existing protective structures for household fiber optic cable connectors have low compressive strength. When the outer protective structure is subjected to pressure during use, it is prone to deformation and cracking, squeezing the internal fiber optic cable and connector, affecting the connection. Furthermore, when the outer protective structure is damaged, the entire structure needs to be replaced. Some protective shells have a buffer structure on the inside, such as a buffer pad, so replacing the entire structure would be wasteful. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a pressure-resistant protection device for optical cable joints, which more accurately solves the problems described above.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a pressure-resistant protection device for optical cable joints, including a first protective shell and a second protective shell. Two connecting components are provided between the first protective shell and the second protective shell. The two connecting components are located on the upper and lower surfaces of the first protective shell and the second protective shell, respectively. Both the first protective shell and the second protective shell are provided with through holes. A first reinforcing plate and a second reinforcing plate are slidably placed on the inner walls of the first protective shell and the second protective shell. A support rod is fixedly connected between the first reinforcing plate and the second reinforcing plate.

[0007] Preferably, the support rod includes a fixed cylinder and a sliding rod, the fixed cylinder is fixedly connected to the second reinforcing plate, the sliding rod is fixedly connected to the first reinforcing plate, the sliding rod is slidably connected to the fixed cylinder, and a spring is fixedly connected between the sliding rod and the fixed cylinder.

[0008] Preferably, the connecting assembly includes a first mounting base and a second mounting base. The first mounting base is fixedly connected to a first protective shell, and the second mounting base is fixedly connected to a second protective shell. A screw is fixedly connected to one side of the second mounting base. The first mounting base is provided with a circular through groove, and a rotating tube is rotatably connected to the side wall of the circular through groove. The inner wall of the rotating tube is provided with a threaded groove.

[0009] Preferably, the rotating tube is fixedly connected to the operating ring on the side away from the second mounting base.

[0010] Preferably, fixing seats are fixedly connected to both sides of the first protective shell, and insert plates are fixedly connected to one side of each of the two fixing seats.

[0011] Preferably, the support rods are located on both sides of the first and second reinforcing plates near the side walls, and the distance between the two support rods is greater than the width of the optical cable joint.

[0012] The optical cable joint pressure-resistant protection device proposed in this utility model can bring the following beneficial effects:

[0013] 1. By setting up a first protective shell, a second protective shell, a first reinforcing plate, a second reinforcing plate, and a support rod, the first and second protective shells are fitted onto the optical cable. The first and second reinforcing plates and the support rod in the middle are placed inside the first and second protective shells, respectively. The first and second protective shells are pushed together and connected by a connecting component to wrap the joint in the middle.

Detailed Implementation

[0020] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0021] like Figures 1-4 As shown, an embodiment of this utility model proposes a pressure-resistant protection device for optical cable joints, including a first protective shell 1 and a second protective shell 2. Two connecting components 3 are provided between the first protective shell 1 and the second protective shell 2, located on the upper and lower surfaces of the first protective shell 1 and the second protective shell 2, respectively. Both the first protective shell 1 and the second protective shell 2 have through holes. A first reinforcing plate 4 and a second reinforcing plate 5 are slidably placed on the inner walls of both the first protective shell 1 and the second protective shell 2. Support rods 6 are fixedly connected between the first reinforcing plate 4 and the second reinforcing plate 5, located on both sides of the first reinforcing plate 4 and the second reinforcing plate 5 near the side walls. The distance between the two support rods 6 is greater than the width of the optical cable joint. Before installing the optical cable joint, the first protective shell 1 and the second protective shell 2 are first fitted onto the two optical cables to be connected, simply allowing the optical cables to pass through the through holes in the first protective shell 1 and the second protective shell 2. Then, the joint is installed on the two optical cables, with the first protective shell 1 and the second protective shell 2 respectively... Place the first reinforcing plate 4 and the second reinforcing plate 5, along with the intermediate support rod 6. The size of the first reinforcing plate 4 and the second reinforcing plate 5 is the same as the size of the inner walls of the first protective shell 1 and the second protective shell 2. After the optical cable connector is connected, push the first protective shell 1 and the second protective shell 2 together through the connecting component 3, thus enclosing the connector in the middle. At this time, the first reinforcing plate 4 and the second reinforcing plate 5 inside the first protective shell 1 and the second protective shell 2 respectively abut against each other. The connector is located between the first reinforcing plate 4 and the second reinforcing plate 5, supported by multiple support rods 6 on the side. The first protective shell 1 and the second protective shell 2 form the first layer of protection, and the first reinforcing plate 4 and the second reinforcing plate 5 form the second layer of protection, improving the protection capability of the connector. At the same time, the first reinforcing plate 4 and the second reinforcing plate 5 can be removed. Even if the first protective shell 1 and the second protective shell 2 or the first reinforcing plate 4 and the second reinforcing plate 5 are damaged due to impact, they can be replaced accordingly, making it flexible and convenient to use.

[0022] like Figure 2 and Figure 3As shown, the support rod 6 includes a fixed cylinder 61 and a sliding rod 62. The fixed cylinder 61 is fixedly connected to the second reinforcing plate 5, and the sliding rod 62 is fixedly connected to the first reinforcing plate 4. The sliding rod 62 is slidably connected to the fixed cylinder 61, and a spring 63 is fixedly connected between the sliding rod 62 and the fixed cylinder 61. The support rod 6 is composed of the sliding rod 62, the fixed cylinder 61, and the spring 63. The optical cable connector is located between the first reinforcing plate 4, the second reinforcing plate 5, and the support rod 6. At the same time, the distance between the first reinforcing plate 4, the second reinforcing plate 5, and the support rod 6 is greater than the size of the connector, providing sufficient deformation distance for the first protective shell 1, the second protective shell 2, the first reinforcing plate 4, and the second reinforcing plate 5. When the outer side is impacted, the impact force is transmitted to the innermost support rod 6. Through the sliding rod 62 and the spring 63, the impact force can be dissipated, improving the impact resistance.

[0023] like Figure 2 and Figure 4 As shown, the connecting assembly 3 includes a first mounting base 31 and a second mounting base 32. The first mounting base 31 is fixedly connected to the first protective shell 1, and the second mounting base 32 is fixedly connected to the second protective shell 2. A screw 33 is fixedly connected to one side of the second mounting base 32. The first mounting base 31 is provided with a circular through groove, and a rotating tube 34 is rotatably connected to the side wall of the circular through groove. The inner wall of the rotating tube 34 is provided with a threaded groove, and an operating ring 7 is fixedly connected to the side of the rotating tube 34 away from the second mounting base 32. When connecting the first protective shell 1 and the second protective shell 2, the first protective shell 1 and the second protective shell 2 are connected together. Align the screw 33 on the second protective shell 2 with the rotating tube 34. Then align the screw 33 with the rotating tube 34 and rotate the rotating tubes 34 on both sides to make the screw 33 gradually pass through the rotating tube 34, while simultaneously pulling the distance between the first protective shell 1 and the second protective shell 2 closer, until the first protective shell 1 and the second protective shell 2 are tightly pressed together, covering the joint. At this time, the rotating tube 34 and the screw 33 not only provide a fastening connection, but also prevent the first protective shell 1 and the second protective shell 2 from bending at the middle contact surface, which would cause the inner wall to squeeze the joint and cause it to break.

[0024] like Figure 1 and Figure 4 As shown, fixing seats 8 are fixedly connected to both sides of the first protective shell 1, and insert plates 9 are fixedly connected to one side of each of the two fixing seats 8. Fixing blocks 10 are fixedly connected to both sides of the second protective shell 2. Each side of the fixing block 10 is provided with a slot, which cooperates with the insert plate 9. When the screw 33 is aligned with the rotating tube 34, the insert plate 9 is aligned with the slot on the fixing block 10. As the rotating tube 34 rotates, the first protective shell 1 and the second protective shell 2 approach each other until they are tightly pressed together. During this process, the insert plate 9 is gradually inserted into the slot on the fixing block 10, which further improves the bending resistance between the first protective shell 1 and the second protective shell 2, thereby improving the pressure resistance effect.

[0025] Working principle: The optical cable passes through the through holes on the first protective shell 1 and the second protective shell 2. The first protective shell 1 and the second protective shell 2 are then fitted onto the optical cable. The first reinforcing plate 4 and the second reinforcing plate 5, as well as the middle support rod 6, are placed inside the first protective shell 1 and the second protective shell 2, respectively. A connector is installed and connected at the end of the optical cable. The screw 33 on the first protective shell 1 and the second protective shell 2 is aligned with the rotating tube 34, and the insertion plate 9 is aligned with the slot on the fixing block 10. The rotating tubes 34 on both sides are turned to start rotating, so that the screw 33 gradually passes through the rotating tube 34, while simultaneously pulling the distance between the first protective shell 1 and the second protective shell 2 closer together until the first protective shell 1 and the second protective shell 2 are tightly pressed together, covering the connector.
