[0002] This innovative device is designed to meet the critical requirement of heating and curing heat shrink tubing after fiber optic fusion splicing. It overcomes the limitations of traditional integrated heating devices and fiber optic fusion splicers, adopting a split structure with unique design and functional features. It mainly consists of two parts: a heating element and a control unit. The heating element typically uses high-efficiency heating elements, such as ceramic heating plates or resistance wire heating rods. These elements can quickly generate heat and evenly transfer it to the heat shrink tubing, ensuring uniform heating of the tubing in a short time, effectively protecting and reinforcing the fusion joint. The cavity design of the heating element is closely matched to the size of the heat shrink tubing, accommodating heat shrink tubing of different specifications while ensuring efficient heat utilization and minimizing heat loss.

[0003] However, after heating the heat shrink tubing, it is usually necessary to wait for a certain period of time to cool it before it can be removed from the heating device. After removal, external tools are also required, which increases the completion time of a single fiber optic splicing task. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figure 1-4 The present invention relates to a novel split-type heating device for an optical fiber fusion splicer, comprising a working chamber 1 and a cover plate 3 installed on the upper side of the working chamber 1.

[0027] The upper inner wall of the working chamber 1 is provided with an upward-opening heating chamber 6;

[0028] The working chamber 1 is equipped with a heating unit 11;

[0029] A heating wire 12 is installed inside the working chamber 1 and below the heating chamber 6. Open the cover plate 3, put the heat shrink tube to be heated onto the spliced ​​optical fiber, and put it into the heating chamber 6. Then close the cover plate 3 and turn on the device. After receiving the start signal, the heating unit 11 starts to work and supplies power to the heating wire 12. The heat generated by the heating wire 12 is first transferred to the air in contact with it through heat conduction, which raises the temperature of the air at the bottom of the heating chamber 6. The hot air is in full contact with the surface of the heat shrink tube and the heat is transferred to the heat shrink tube through heat convection. When the preset heating time is reached, the control circuit cuts off the power supply to the heating wire 12 and stops heating. Open the cover plate 3 and take the heat shrink tube out of the heating chamber 6.

[0030] Inside the heating chamber 6, near the left and right sides, are clamping plates a9 and b10 respectively. Multiple support rings 18 are fixedly connected to the lower outer walls of clamping plates a9 and b10. When heating the heat shrink tubing, clamping plates a9 and b10 are first placed inside the heating chamber 6, and then the heat shrink tubing is placed on the support rings 18. After the heat shrink tubing is heated, the operator can lift clamping plates a9 and b10 upwards to move the support rings 18 and the heat shrink tubing upwards together, making the removal of the heat shrink tubing simple and convenient, avoiding the problem of damage to the heat shrink tubing or optical fiber that may be caused by difficulty in removal in the traditional method.

[0031] like Figure 3 and Figure 4 As shown, a limiting plate 16 is fixedly connected to the upper outer wall of the clamping plate b10. A handle 17 is fixedly connected to the upper outer wall of the limiting plate 16 near the right side, so that the clamping plate a9 and the clamping plate b10 can be moved upward under the action of external force.

[0032] When it is necessary to remove clamps a9 and b10, pinch the handle 17 and slowly lift it in a tilted direction to one side during the lifting process. This provides a tilting driving force during the movement, allowing the heated heat shrink tubing to sway on the support ring 18, reducing its stickiness and facilitating subsequent removal.

[0033] like Figure 4 As shown, a connecting rod a13 is provided on the outer wall of the right end of the clamping plate a9 and near the front and rear sides respectively, and a connecting rod b15 is provided on the outer wall of the left end of the clamping plate b10 and near the front and rear sides respectively. A connecting shaft 14 is provided between the two connecting rods a13 and the connecting rod b15.

[0034] After removing clamps a9 and b10 using handle 17, the upper sides of clamps a9 and b10 can be pinched and force applied towards the center. Under the constraint of connecting shaft 14, the multiple support rings 18 on the left and right sides can open to the left and right, allowing the lifted heat shrink tubing to be lowered and discharged.

[0035] like Figure 2 As shown, the lower inner wall of the cover plate 3 is provided with grooves for the limiting plate 16 and the handle 17 to be accommodated.

[0036] After the cover plate 3 is closed, the corresponding groove on the cover plate 3 can accommodate the limiting plate 16 and the handle 17, so that the cover plate 3 can maintain its original closure and sealing after closing.

[0037] like Figure 3 As shown, the working chamber 1 is equipped with an observation unit 8 to detect whether there is heat shrink tubing inside the heating chamber 6, and the working chamber 1 is equipped with a controller 7 to control the start and stop of various electronic devices.

[0038] The observation unit 8 inside the working chamber 1 starts working, detecting whether heat shrink tubing is placed inside the heating chamber 6. The observation unit 8 can detect this using optical sensors, infrared sensors, or other methods. If heat shrink tubing is detected, the observation unit 8 will send a signal back to the controller 7. Heating can only be started after heat shrink tubing has been detected.

[0039] like Figure 1 and Figure 2 As shown, a rotating shaft 5 is provided between the working chamber 1 and the cover plate 3. A handle 2 is fixedly connected to the outer wall of the right end of the cover plate 3 near the front side, so that the cover plate 3 can be rotated around the rotating shaft 5 as the center of rotation under the action of external force.

[0040] The operator can push the handle 2 to flip the cover 3 upwards around the pivot 5, thus exposing the heating chamber 6.

[0041] like Figure 1 As shown, an observation window 4 is embedded inside the upper outer wall of the cover plate 3.

[0042] Operators can observe the situation inside the heating chamber 6 in real time through the observation window 4 embedded in the upper outer wall of the cover plate 3, such as the heating status of the heat shrink tubing and whether there are any abnormalities.

[0043] The implementation principle of this embodiment is as follows: Open the cover plate 3, place the heat shrink tubing to be heated onto the spliced ​​optical fiber, and put it into the heating chamber 6. Then close the cover plate 3, and turn on the device. After receiving the start signal, the heating unit 11 starts working and supplies power to the heating wire 12. The heat generated by the heating wire 12 is first transferred to the air in contact with it through heat conduction, which raises the temperature of the air at the bottom of the heating chamber 6. The hot air makes full contact with the surface of the heat shrink tubing, and the heat is transferred to the heat shrink tubing through heat convection. When the preset heating time is reached, the control circuit cuts off. Disconnect the power supply to the heating wire 12 to stop heating. Open the cover plate 3 and remove the heat shrink tubing from the heating chamber 6. When heating the heat shrink tubing, first place the clamping plates a9 and b10 inside the heating chamber 6, and then place the heat shrink tubing on the support ring 18. After the heat shrink tubing is heated, the operator can lift the clamping plates a9 and b10 upwards to move the support ring 18 and the heat shrink tubing upwards together, making the removal of the heat shrink tubing simple and convenient, avoiding the problem of damage to the heat shrink tubing or optical fiber that may be caused by difficulty in removal in the traditional method.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
