[0002] The optical fiber preform sintering furnace is a key piece of equipment in the optical fiber manufacturing process. It is used to sinter the preform in a high-temperature environment to form a dense and uniform optical glass structure, thereby meeting the requirements of optical fiber transmission performance.

[0003] Currently, temperature controllers (E5CC series temperature controllers) are used to control the temperature in optical fiber preform sintering furnaces. However, the structure of these temperature controllers is simple. They are usually fixed to the temperature controller by screws. This installation method makes it difficult to install and remove the temperature controller. If the buttons or display on the temperature controller are damaged, it will take a lot of time to replace them, which will affect the production of optical fibers. Summary of the Invention

Conductive columns are clamped and fixed in each clamping channel. The other end of each conductive column is enlarged to form a fixing part. The fixing parts are installed in the through holes. Extrusion fixing mechanisms are installed on both sides of the housing.

[0006] As a preferred technical solution, the extrusion fixing mechanism includes a pressure plate and a positioning plate. The two sides of the housing protrude to form thickened parts.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a temperature control device for an optical fiber preform sintering furnace according to this utility model includes a housing 2 and a temperature controller 1 for controlling the temperature of the sintering furnace. One end of the temperature controller 1 is inserted into the housing 2. The temperature controller 1 has multiple grooves 16 on both sides inside the housing 2. Each groove 16 has a conductive pressure-bearing column 9 connected to the main board inside the temperature controller 1. Each groove 16 has a conductive extrusion block 8 in an opening on one side. Each conductive extrusion block 8 and the conductive pressure-bearing column 9 has an arc-shaped groove on their opposite surfaces. Adjacent arc-shaped grooves are combined to form a clamping channel. Each end of the housing 2 away from the temperature controller 1 has a through hole opposite the clamping channel. Each clamping channel clamps and fixes a conductive column 10. The other end of each conductive column 10 is enlarged to form a fixing part 7. The fixing part 7 is installed in the through hole. Extrusion fixing mechanisms are installed on both sides of the housing 2.

[0024] In this embodiment, the extrusion fixing mechanism includes a pressure plate 12 and a positioning plate 14. The two sides of the housing 2 protrude to form thickened portions 4. The inner side of the housing 2 is provided with a limiting groove facing the thickened portion 4. One end of the limiting groove extends into the inside of the thickened portion 4. The pressure plate 12 is disposed in the limiting groove. One side of the pressure plate 12 protrudes to form an extrusion portion 13 facing the conductive extrusion block 8. One end face of the extrusion portion 13 is in contact with the conductive extrusion block. The temperature controller 1 is provided with positioning grooves on both sides. One end of the positioning plate 14 is inserted into the positioning groove, and the other end is mounted on the pressure plate 12. The length and width of the limiting groove match the length and width of the pressure plate, so that the pressure plate can only move back and forth along the limiting groove.

[0025] In this embodiment, the pressing and fixing mechanism also includes a handwheel 3, a screw 11, and a bearing. The bearings are all embedded on the outer side of the pressure plate 12. The outer side of the thickened part 4 is provided with a first screw hole opposite the inner ring of the bearing. The screw 11 is threaded into the first screw hole. One end of the screw 11 is installed in the inner ring of the bearing, and the other end of the screw 11 is set to the outside and is equipped with a handwheel 3. The handwheel facilitates the rotation of the screw and drives the movement of the pressure plate.

[0026] In this embodiment, each of the exposed end faces of the fixing part 7 is provided with a second screw hole, and each of the second screw holes is threaded with a locking screw 6 for pressing and fixing the cable. The external cable can be bent and fitted onto the locking screw. After the locking screw is rotated, it can be pressed and fixed on the fixing part to complete the stable connection between the thermostat, the conductive post and the cable.

[0027] In this embodiment, a thickened sleeve 15 is installed on a section of the conductive post 10 located inside the housing 2, and one end face of the thickened sleeve 15 is arranged to abut against the inner wall surface of the housing 2.

[0028] The thickened sleeve, pressure plate, and housing are all made of insulating plastic material to prevent electrical conduction between them.

[0029] In this embodiment, one end of the housing 2 is provided with multiple fixing holes 5, through which bolts can pass and, together with nuts, fix the housing in the equipment housing.

[0030] In this embodiment, the length and width of the thermostat 1 located inside the housing 2 match the length and width of the inner cavity of the housing 2, which increases the stability of the thermostat after it is inserted.

[0031] In this embodiment, grooves 17 are provided on both sides of the groove 16, and sliders 18 are formed by protrusions on both sides of the conductive extrusion block 8. The sliders 18 are slidably disposed in the grooves 17. The conductive extrusion block can be positioned by the grooves and sliders, so that the conductive extrusion block can only move back and forth along the grooves, avoiding falling directly out of the groove.

[0032] During installation, first insert the conductive extrusion block into the groove, but do not make contact between the conductive extrusion block and the conductive pressure column, so that after the thermostat is inserted into the housing, one end of the conductive column can be inserted into the clamping channel between the conductive extrusion block and the conductive pressure column;

[0033] After the above is completed, the screw is rotated by handwheel, causing the screw to move inward along the screw hole. The movement of the screw drives the pressure plate, which in turn drives the positioning plate and the extrusion part. The extrusion part squeezes the conductive extrusion block by bringing them together, causing the conductive extrusion block to move toward the conductive pressure post, thereby clamping and fixing the inserted conductive post to ensure the connection stability between the thermostat, the conductive post, and the external cable.

[0034] The positioning plate can be inserted into the positioning groove and abut against the positioning groove. The positioning plate can simultaneously press and restrict the temperature controller, so that the temperature controller can be fixed in the housing.

[0035] Since the temperature controller can be fixed to the housing and the conductive post by moving the pressure plate, rotating the handwheel in the opposite direction will cause the pressure plate and the positioning plate to move outward by moving the screw. This will cause the pressure exerted by the extrusion part on the conductive extrusion block to disappear, and the positioning plate can be moved out of the positioning slot. At this time, the temperature controller can be directly removed from the housing, which greatly increases the efficiency of replacement and reduces the waste in the middle, so as to meet the needs of the optical fiber preform sintering furnace.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
