[0023] The following will describe in detail the embodiments of the present utility model with reference to the accompanying drawings.

[0024] As Figures 1 to 7 shown, the present utility model discloses an optical fiber thermal stripper, which includes a base body 1. The base body 1 is rotatably connected with a heating pressing cover 2. The base body 1 is provided with a heating sheet 11 and a first stripping knife 12. The heating pressing cover 2 is provided with a pressing plate 21 cooperating with the heating sheet 11 and a second stripping knife 22. When the heating pressing cover 2 rotates to cover the heating sheet 11, the positions of the first stripping knife 12 and the second stripping knife 22 correspond to each other. One side of the base body 1 is slidably connected with a fixture seat 3. The fixture seat 3 is rotatably connected with a fixture pressing cover 4. The base body 1 is further provided with a mounting plate 5. The upper part of the mounting plate 5 is provided with a supporting part 51 extending upward. The heating sheet 11 abuts against the supporting part 51, so that a heat insulation gap 6 is left between the heating sheet 11 and the mounting plate 5. The lower part of the mounting plate 5 is provided with a heat insulation groove 52 for further heat insulation.

[0025] The seat body 1 serves as the main body of the thermal stripper. The heating cover 2 is rotatably connected to the seat body 1. The heating cover 2 and the seat body 1 cooperate to enclose the optical fiber and heat its protective layer. The heating sheet 11 provided on the seat body 1 can generate heat, and while the pressing plate 21 provided on the heating cover 2 evenly distributes the heat, it restricts the movement of the optical fiber during the heating process, ensuring that the optical fiber is stably placed within the heating area. Ensuring that the protective layer of the optical fiber is evenly heated helps to improve the stripping efficiency and quality. The second stripping knife 22 is installed on the heating cover 2. When the heating cover 2 is closed, the second stripping knife 22 cooperates with the first stripping knife 12 on the seat body 1 to act on the protective layer of the optical fiber together to achieve the cutting purpose. The fixture seat 3 can fix the optical fiber during the heating and stripping processes. By slidingly connecting the fixture seat 3 to one side of the seat body 1, the softened protective layer of the optical fiber after heating can be separated from the optical fiber. The fixture cover 4 is rotatably connected to the fixture seat 3, thereby realizing the opening and closing of the fixture cover 4. When the fixture cover 4 is closed, the fixture cover 4 cooperates with the fixture seat 3 to fix the optical fiber. The mounting plate 5 is installed on the seat body 1 to provide support and a mounting position for the heating sheet 11. The mounting plate 5 can be made of a material with a low thermal conductivity to reduce the conduction of heat to the seat body 1 and protect the seat body 1 from high temperatures. The support portion 51 extends upward from the upper part of the mounting plate 5 to support the heating sheet 11. By abutting against the heating sheet 11, the stability and correct mounting position of the heating sheet 11 are ensured. The heat insulation gap 6 is formed between the heating sheet 11 and the mounting plate 5 to isolate heat and reduce the direct transfer of heat to the mounting plate 5 and the seat body 1, thereby reducing heat loss. The lower part of the mounting plate 5 is provided with a heat insulation groove 52 for further heat insulation, using air as a poor heat conduction medium to reduce the conduction of heat generated by the heating sheet 11 to the seat body 1.

[0026] Through the heat insulation groove 52 opened in the lower part of the mounting plate 5 and the setting of the heat insulation gap 6 left between the heating sheet 11 and the mounting plate, the mounting plate 5 adopts a hollow design with double-sided heat insulation on the upper and lower surfaces, effectively preventing the heat loss of the heating sheet 11, while improving the safety and durability of the equipment, and at the same time, improving the stripping speed of the optical fiber protective layer and the operation stability.

[0027] The support portion 51 is provided on both sides of the mounting plate 5. The upper part of the mounting plate 5 is detachably connected with a limiting plate 53, and the heating sheet 11 is arranged between the support portion 51 and the limiting plate 53.

[0028] The support portions 51 are respectively arranged on both sides of the mounting plate 5 to support both sides of the heating sheet 11, reducing the contact area between the heating sheet 11 and the support portion 51. The limiting plate 53 is detachably connected to the upper part of the mounting plate 5 and is located above the support portion 51. Together with the support portion 51, it limits the position of the heating sheet 11 to ensure that the heating sheet 11 is firmly installed on the mounting plate 5.

[0029] An installation groove 54 for installing the heating sheet 11 is provided in the upper part of the supporting part 51, and the limiting plate 53 covers the installation groove 54 when installed on the upper part of the installation plate 5.

[0030] The installation groove 54 is provided on one side close to the middle of the installation plate 5. By providing the installation groove 54 on both sides of the supporting part 51, the contact area between the heating sheet 11 and the supporting part 51 is further reduced. The limiting plate 53 covers the installation groove 54 when installed on the upper part of the installation plate 5, thereby fixing the heating sheet 11 in the installation groove 54.

[0031] There are multiple supporting parts 51, which are arranged at intervals along the length direction of the installation plate 5, and a connecting rod 55 is provided between adjacent supporting parts 51 on the same side.

[0032] There are multiple supporting parts 51, which are arranged at intervals along the length direction of the installation plate 5, thereby reducing the contact area between the heating sheet 11 and the supporting part 51. The connecting rod 55 is provided between adjacent supporting parts 51 on the same side, increasing the structural strength between the supporting parts 51 and ensuring the stability of the overall structure.

[0033] An abutting part 56 is provided in the heat insulation groove 52. The abutting part 56 is arranged in the heat insulation groove 52 for supporting the installation plate 5 and reducing the conduction of heat from the installation plate 5 to the seat body 1.

[0034] The abutting part 56 is cross-shaped, and the four ends of the cross-shaped abutting part 56 are connected to the groove wall of the heat insulation groove 52. The cross-shaped abutting part 56 is connected to the groove wall of the heat insulation groove 52 through the four ends, which can enhance the structural stability in the heat insulation groove 52 and prevent the installation plate 5 from being deformed by heat.

[0035] The abutting part 56 and the installation plate 5 are integrally formed. The integrally formed design can ensure that there is no additional joint or connection point between the abutting part 56 and the installation plate 5, which helps to improve the strength and durability of the overall structure. At the same time, the integrally formed design reduces the assembly steps, simplifies the production process, and reduces the manufacturing cost.

[0036] In the embodiment, the heating sheet 11, the first stripping knife 12, the pressing plate 21, and the second stripping knife 22 are all widened to be compatible with the stripping of the protective layer of ribbon optical fibers with more than 12 cores and the batch stripping of the protective layers of multiple bare optical fibers and pigtails at one time, effectively improving the efficiency of stripping the protective layer of optical fibers.

[0037] A guide sleeve 13 is provided at one end of the seat body 1 close to the fixture seat 3. A guide rod 31 matching with the guide sleeve 13 is provided on the fixture seat 3, and a detachable connection structure 7 is provided between the guide rod 31 and the seat body 1.

[0038] The guide sleeve 13 is provided at one end of the seat body 1 close to the fixture seat 3 to guide the fixture seat 3 to slide along the seat body 1 and ensure the smooth movement of the fixture seat 3.

[0039] The guide rod 31 is arranged on the fixture seat 3 and inserted into the guide sleeve 13, enabling the fixture seat 3 to slide on the seat body 1. The detachable connection structure 7 is arranged between the guide rod 31 and the seat body 1, making the guide rod 31 and the seat body detachable, facilitating the user to operate to remove and install the fixture seat 3, thereby achieving free switching between the two forms of the ribbon fiber heat stripper and the pigtail fiber heat stripper.

[0040] The detachable connection structure 7 includes a clamping groove 71 arranged on the guide rod 31, a clamping pin 72 arranged in the seat body 1, and the clamping pin 72 is connected with a sliding switch 73 capable of driving the clamping pin 72 to insert into or disengage from the clamping groove 71.

[0041] The clamping groove 71 is arranged on the guide rod 31, the clamping pin 72 is arranged in the seat body 1, and the number and position of the clamping groove 71 match those of the clamping pin 72, so as to cooperate with the clamping groove 71 to lock the guide rod 31. The sliding switch 73 can control the movement of the clamping pin 72 to enable it to insert into or disengage from the clamping groove 71.

[0042] The detachable connection structure 7 can also be realized by means of snap connection, magnetic attraction connection, etc.

[0043] The sliding switch 73 is arranged at the bottom of the seat body 1. Arranging the sliding switch 73 at the bottom of the seat body 1 can reduce the occurrence of misoperation by the user during normal use.

[0044] During use, according to the type of optical fiber, the state of the clamping pin 72 is adjusted through the sliding switch 73 to make the clamping pin 72 insert into or disengage from the clamping groove 71, so as to install or remove the fixture seat 3. Then, the optical fiber to be processed is placed into the space between the seat body 1 and the heating pressing cover 2, and the fixture pressing cover 4 is used to fix one end of the optical fiber on the fixture seat 3. The heating pressing cover 2 is closed. At this time, the pressing plate 21 applies a certain pressure to the optical fiber, and at the same time, the positions of the first stripping knife 12 and the second stripping knife 22 correspond. The heating sheet 11 starts to heat, and the heat loss of the heating sheet 11 is reduced through the heat insulation gap 6 and the heat insulation groove 52, so that more heat generated by the heating sheet 11 is transferred to the optical fiber protective layer. After the protective layer is softened, the first stripping knife 12 and the second stripping knife 22 act together to complete the cutting of the protective layer to strip the protective layer, thus completing the process of stripping the optical fiber protective layer.
