Description
Technical Field
[0001] The utility model belongs to the technical field of drying, and in particular relates to a drying fixture and a drying device applied to optical fiber connectors and ferrules. Background Art
[0002] Drying refers to the process of removing solvents and retaining solid content in some way. It usually refers to the process of passing hot air to evaporate and take away the moisture in the material.
[0003] At present, the ferrule is a precisely aligned cylinder in the fiber optic connector plug, with a micro hole in the center, which is used to fix the optical fiber. After the ferrule and the optical fiber are fixed, the ferrule joint needs to be fixed to the outer shell of the optical fiber connector. The commonly used method of fixing the ferrule joint and the optical fiber connector is: first use glue to bond the ferrule and the core of the optical fiber, and then embed the ferrule in the connector shell, that is, after applying glue in the inner hole of the ferrule, insert the core of the optical fiber into the hole of the ferrule after applying glue, and heat the glue in the inner hole of the ferrule through a heating device, so that the glue solidifies and the ferrule and the core are fixed. Then, the fixed ferrule is embedded in the embedding groove of the connector shell, thereby fixing the front end of the optical fiber cable to the connector shell.
[0004] However, when the above-mentioned drying and fixing method is adopted, the heating temperature uniformity of the fiber core of the ferrule and the connector during the drying process is poor, and due to the large difference in the weight of the fiber core and the ferrule, the fiber core often experiences fiber debonding, misalignment, or the optical fiber tilts inside the ferrule during the drying process, making it difficult to ensure a good connection between the ferrule and the connector. Utility Model Content

The flow groove and the heat preservation component are combined in the design. The heat preservation component maintains the temperature in the receiving groove as much as possible during the drying process to avoid being affected by the external temperature, and the temperature is combined to connect each receiving groove through the flow groove to effectively ensure the uniformity of temperature.

[0034] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.
[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.
[0036] Embodiment 1:
[0037] Please see attached Figure 1-4 The drying fixture of the utility model comprises a placing part 1 and a heat-insulating part 2, wherein the heat-insulating part 2 is covered on the placing part 1; the placing part 1 comprises a placing object 11 symmetrically arranged and a flow groove 12 connected to the placing objects 11 on both sides; the placing object 11 is relatively provided with a first plane 11a and a second plane 11b, wherein the first plane 11a is sunken toward the second plane 11b to form a receiving groove 111, wherein the bottom surface of the receiving groove 111 is parallel to the first plane 11a and is connected to the flow groove 12; the angle formed between the extension surface of the first plane 11a and the extension surface of the second plane 11b is an acute angle α.
[0038] The receiving groove 111 is used to place the ferrule 3 and the optical fiber connector 4. The heat preservation component 2 is used to block the exchange between the temperature of the receiving groove 111 and the external temperature, reducing large temperature changes. The circulation groove 12 is used to connect the various receiving grooves 111, so that the heat can flow into the various receiving grooves 111 through the circulation groove 12, so as to achieve temperature uniformity during the drying process.
[0039] In this embodiment, the operation process of the drying fixture is as follows: first, glue is used to bond the ferrule 3 and the fiber core; secondly, the ferrule 3 and the optical fiber connector 4 are placed in the accommodating groove 111, wherein the ferrule 3 is placed close to one end of the flow groove 12, and its optical fiber connector 4 is tilted toward the side of the ferrule 3 through an acute angle α, which can offset the weight difference between the optical fiber connector 4 and the ferrule 3 and ensure the stability of the placement; then the heat preservation component 2 is covered on the placement object 11; finally, the drying fixture is heated and dried to perform the drying operation.
[0040] Through the arrangement of the above-mentioned storage component 1, the optical fiber connector 4 and the ferrule 3 are placed in a receiving groove 111 with a certain tilt angle, so that the optical fiber connector 4 is subjected to a force toward the middle during the drying process, effectively avoiding undesirable phenomena such as optical fiber debonding, dislocation, and tilting, and improving the good connection effect of the ferrule 3 and the optical fiber connector 4. In addition, the flow groove 12 and the heat preservation component 2 are combined in design. The heat preservation component 2 can reduce the contact time between the receiving groove 111 and the external environment during the drying process, maintain the temperature in the receiving groove 111 as much as possible, reduce the influence of the external temperature, and connect each receiving groove 111 through the flow groove 12 in combination with the temperature, effectively ensuring the uniformity of the temperature. On the other hand, the flow groove 12 also plays a ventilation role, improving the safety of the drying operation. And the temperature is effectively locked by the heat preservation component 2, which can speed up the drying speed and thus improve the drying timeliness.
[0041] In some embodiments, a plurality of accommodating grooves 111 are arranged in a linear array on the object 11. With this arrangement, the drying fixture can perform batch drying operations on the ferrules 3 and the optical fiber connectors 4, increase the drying load, and efficiently complete large batch drying tasks.
[0042] Please see attached Figure 5 , the acute angle α is 4-6 degrees. Specifically, the acute angle α can be flexibly set according to the weight difference between the ferrule 3 and the optical fiber connector 4; when the weight difference is greater, the acute angle α is increased accordingly, and when the weight difference is small, the acute angle α is reduced accordingly to ensure the stability of the placement of the ferrule 3 and the optical fiber connector 4.
[0043] Please see attached Figure 6 In the extending direction of the flow slot 12 along the placement object 11, the accommodating slot 111 includes a first slot 1111 and a second slot 1112 in sequence, and the width of the first slot 1111 is smaller than the width of the second slot 1112. Among them, the first slot 1111 is used for the ferrule 3, and the second slot 1112 is used for placing the optical fiber connector 4. Since the size of the ferrule 3 is smaller than the size of the optical fiber connector 4, the first slot 1111 and the second slot 1112 are respectively set according to the size of the ferrule 3 and the optical fiber connector 4, so as to improve the placement fit and ensure the placement stability.
[0044] The length of the second notch 1112 is greater than the length of the optical fiber connector 4, and the depth of the second notch 1112 is greater than the cross-sectional width of the optical fiber connector 4. With this arrangement, the optical fiber connector 4 is embedded in the second notch 1112, effectively preventing it from changing position due to slight shaking, improving the stability of placement, and thus ensuring a good drying effect.
[0045] Please see attached Figure 7 , limit blocks 112 are provided on both sides of the object 11. Specifically, the heat-insulating component 2 is placed between the limit blocks 112 on both sides. Through this arrangement, when the heat-insulating component 2 is covered, it is convenient for the heat-insulating component 2 to cover the object 11 quickly and accurately, and the placement stability of the heat-insulating component 2 can be ensured, and the convenience of placing the heat-insulating component 2 is improved.
[0046] Please see attached Figure 8 The heat preservation component 2 includes a heat preservation plate 21, a heat insulating plate 22 and a handle 23. The heat insulating plate 22 is connected between the heat preservation plate 21 and the handle 23. Specifically, the heat preservation plate 21 maintains the heat in the receiving groove 111 as much as possible. The heat insulating plate 22 blocks the temperature on the heat preservation plate 21 to prevent the heat from being transferred to the handle 23, thereby improving the operation safety; on the other hand, it can also reduce the loss of heat in the receiving groove 111 and ensure the drying efficiency; the handle 23 is used to take the heat preservation plate 21 for easy operation.
[0047] In some embodiments, the insulation board 21 is an aluminum alloy insulation board 21. The aluminum alloy has a uniform heat dissipation property, which can ensure that the ferrule 3 and the optical fiber connector 4 in the receiving groove 111 are uniformly heated.
[0048] Embodiment 2:
[0049] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the storage component 1 of the utility model.
[0050] See also Fig. 9 The storage component 1 of this embodiment further includes a heat balancing tube 113, which is embedded in the first notch 1111, and is a U-shaped heat balancing tube 113. Specifically, the heat balancing tube 113 is an aluminum alloy heat balancing tube 113. Aluminum alloy has a uniform heat dissipation property, thereby ensuring that the ferrule 3 is heated uniformly. And by setting the heat balancing tube 113 as a U-shaped heat balancing tube 113, the clamping operation of the ferrule 3 is facilitated.
