Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber communication, in particular to an optical fiber fusion splicer with a compression tube structure. Background Art

[0002] The main material that constitutes optical fiber is quartz glass. The characteristic of glass is that it is fragile. Conventional optical fiber is a glass thread with a diameter of φ125 microns. The main function of the optical fiber fusion splicer is to fuse two optical fibers together to form a light-transmitting circuit to meet the needs of optical signal communication transmission. Since the fiber optic joints after docking cannot withstand the external force of construction operations, the joints need to be protected by sleeves to meet the purpose of the fiber optic joints being pulled and flexible. The fiber optic joints wrapped in the heat shrink tube material are heat-shrunk and reinforced through the fusion splicer "heater" to achieve protection.

[0003] There are currently a small number of well-adopted "non-heating plate pressed heat shrink tube" heating processes in the existing welding machine heaters, but there is no more efficient auxiliary heating design and device like "heating plate pressed heat shrink tube". That is, a small number of manufacturers in the industry have solved the problem of insufficient heat conduction in the "suspended" contact between the plastic "heat shrink tube" and the "V-groove" of the heating element heating core, but there is still only two heat conduction surfaces, which is not as efficient as three heat conduction surfaces, making it inconvenient for daily use. Utility Model Content

[0004] The purpose of the utility model is to provide an optical fiber fusion splicer with a press-tube structure, which increases the heat conduction area of ​​the heating element and the heat receiving element by cooperating with the wire and the single heating plate, thereby improving the working thermal efficiency of the heater of the optical fiber fusion splicer and extending the battery life of the lithium battery.

[0005] The utility model is realized through the following technical solutions:

[0006] The utility model is a fiber optic fusion splicer with a pressed tube structure, comprising a shell, a rotating shaft and an upper cover. The top opening of the shell is rotatably connected to the upper cover through the rotating shaft. A V-groove heating element is installed inside the shell, and a heat shrink tube is placed at the opening of the V-groove heating element. A single heating sheet is provided on one side of the inner wall of the upper cover, and wires are connected to both ends of the single heating sheet.

[0007] Furthermore, the outer shell is in the shape of a rectangular box with an open top surface, and the bottom surface of the upper cover is connected to the open top surface of the outer shell.

[0008] Furthermore, the V-groove heating element is formed by two inclined heating surfaces to form a "V"-shaped groove body that is wider at the top and narrower at the bottom.

[0009] Furthermore, the heat shrink tube is in the shape of a cylinder with two ends open, and the bottom surface of the heat shrink tube is arranged to abut against the side wall of the opening of the V-groove heating element.

[0010] Furthermore, the single heating sheet is vertically arranged on the bottom surface of the upper cover, and the length of the single heating sheet matches the length of the V-groove heating element.

[0011] The utility model has the following beneficial effects:

[0012] The utility model increases the heat conduction area of ​​the heating element and the heat receiving element by cooperating with the wire and the single heating plate, thereby improving the working thermal efficiency of the heater of the optical fiber fusion splicer and extending the battery life of the lithium battery. The "heating plate pressing the heat shrink tube" device is added to the heater component of the optical fiber fusion splicer, which can shorten the heating operation time for the user by 1 time and effectively extend the battery life of the lithium battery by about 30% or more, effectively improving the working efficiency of the user in using the optical fiber fusion splicer and extending the operation time of the optical fiber project. Therefore, it also reduces the number of times the user operates to charge the lithium battery, saves charging costs, and extends the service life of the standard lithium battery of the fusion splicer. Energy saving and consumption reduction bring certain economic and social benefits to the user, and the energy saving and consumption reduction effect is obvious.

[0013] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4The utility model provides a technical solution: an optical fiber fusion splicer with a press-tube structure, comprising a shell 1, a rotating shaft 2 and an upper cover 3. The top opening of the shell 1 is rotatably connected to the upper cover 3 by the rotating shaft 2. The shell 1 is in the shape of a rectangular box with an open top surface, providing stable installation space and protection for the internal components. The bottom surface of the upper cover 3 is connected to the top surface of the opening of the shell 1, so that the upper cover 3 can be flexibly opened and closed, which is convenient for operation and maintenance of the internal components. When the upper cover 3 is closed, its bottom surface can be tightly covered with the top surface of the opening of the shell 1, forming a relatively closed internal environment, which is conducive to reducing the influence of external interference on the fusion process. A V-groove heating element 4 is installed inside the shell 1. The V-groove heating element 4 is composed of two inclined The heating surface forms a "V"-shaped groove that is wide at the top and narrow at the bottom, which can accurately adapt to the placement and heating requirements of the optical fiber. The fusion splicer plays an effective protective role by wrapping the optical fiber joints in heat shrink tubing material to heat shrink and reinforce them. The core component of the V-groove heating element 4 is the heating core, which is a power-consuming heating element. The heating element base material is a 0.4mm thick stainless steel sheet with a heating coating printed on the stainless steel surface. Then the left and right pieces of stainless steel are fixed into a "V-groove" structural component. When the heating coating is connected to the circuit and starts to heat up, the "V-groove" heating core becomes a heating element, providing a stable and uniform heating environment for the optical fiber during fusion splicing, ensuring that the optical fiber end face can be fully melted and achieve high-quality connection. A heat shrink tube is placed at the opening of the V-groove heating element 4. Tube 5, the heat shrink tube 5 is a cylindrical shape with two ends open, the tube wall thickness is about 0.6mm, and a φ1*50 steel rod is reserved for reinforcement on the inner side wall of the tube. The heat shrink tube 5 is made of a special plastic material. When placed on the V-groove heating element 4 and heated, it can shrink rapidly when subjected to high temperature, thereby tightly wrapping the protected optical fiber in the tube, enhancing its mechanical strength and stability, and effectively preventing external factors from damaging the fusion joint. The bottom surface of the heat shrink tube 5 is set on the side wall of the opening of the V-groove heating element 4, and a single heating plate 7 is set on one side of the inner wall of the upper cover 3. The two ends of the single heating plate 7 are connected with wires 6, and the wires 6 provide a power transmission channel for the single heating plate 7. The wires at both ends of the single heating plate 7 are connected to the control circuit board, so that In order to realize the temperature control function of the circuit and enable it to work normally, the single heating sheet 7 is vertically arranged on the bottom surface of the upper cover 3. The length of the single heating sheet 7 matches the length of the V-groove heating element 4. The single heating sheet 7 is connected to the bottom surface of the upper cover 3 through an elastic connector. The single heating sheet 7 presses the heat shrink tube 5 at the lower end, which can increase the heating area of ​​the heat shrink tube 5. The heat shrink tube 5 can shrink and change rapidly when heated, and finally quickly and tightly wrap the protected optical fiber in the tube, so as to better realize all-round protection of the optical fiber fusion splicing part, further improve the overall quality and reliability of the optical fiber fusion splicing, and lay a solid foundation for the stable operation of the optical fiber communication network. The V-groove heating element 4 and the single heating sheet 7 mentioned above are both existing technologies and will not be elaborated in detail.
