Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of optical fiber processing, in particular to a core curing tool. Background Art
[0002] The optical fiber ferrule processing process involves multiple precision steps to ensure that the ferrule can be accurately fixed and aligned with the optical fiber, thereby optimizing the transmission efficiency of the optical signal; among them, the optical fiber ferrule curing is an essential step in the ferrule process to ensure an efficient and stable connection between the optical fiber and the ferrule.
[0003] A common curing method is vertical baking for curing, in which a vertical curing limit plate is generally used in conjunction with a heating furnace, and is mainly used in the curing process of a single short ferrule. When the optical fiber to be cured is long and metal parts are installed in the middle of the optical fiber, if the vertical baking method is used, the optical fiber is easily scattered on the curing tooling under the action of the gravity of the metal parts, and then comes into contact with the high-temperature heating platform. At this time, part of the optical fiber is easily damaged by heat melting. At the same time, the end of the optical fiber away from the ceramic ferrule is easily not supported by the metal parts, and the end of the optical fiber is easily offset from the axis of the ceramic ferrule, which will reduce the insertion accuracy of the optical fiber and the ceramic ferrule. In addition, the end of the optical fiber away from the ceramic ferrule will extend outside the tooling. During the curing process, the end of the optical fiber is easily interfered with by other components, and the middle of the optical fiber is also easily pressed and bent, which will affect the quality of the final optical fiber ferrule. Utility Model Content
[0004] In response to the shortcomings of the existing technology, the utility model provides a core curing tool to solve the problem that when a metal part is installed in the middle of the optical fiber, if a vertical baking method is adopted, the optical fiber is easily scattered on the curing tool under the action of the gravity of the metal parts, and the part of the optical fiber is easily damaged by heat melting.
[0005] To achieve the above-mentioned object, the basic scheme of the present invention is as follows: a ferrule curing tool, comprising a ferrule limiting plate, the ferrule limiting plate being arranged horizontally, and a plurality of first limiting grooves for limiting the position of a single ceramic ferrule being arranged horizontally on one side of the ferrule limiting plate, and further comprising:
[0006] The part limiting plate is horizontally mounted on the core limiting plate. The part limiting plate is provided with a plurality of second limiting grooves for limiting individual metal parts, and the first limiting grooves are opposite to the second limiting grooves.
[0007] The technical principle of the present invention is as follows: when curing the optical fiber and the ceramic ferrule, the combination of the ceramic ferrule, the optical fiber, the metal parts and the capillary are placed on the ferrule curing tooling, the ceramic ferrule is horizontally embedded in the first limiting groove, and the metal parts are placed on the second limiting groove. The second limiting groove can support and limit the optical fiber so that the metal parts of the optical fiber are stably supported, avoiding the left and right shaking of the long optical fiber, avoiding the interference between the tail of the optical fiber and other components and being pressed and bent, and also ensuring the stability of the cooperation between the ferrule and the first limiting groove, avoiding the left and right shaking of the optical fiber and preventing the optical fiber from being glued by heat.
[0008] Furthermore, the component limiting plate and the core limiting plate are detachably connected.
[0009] Through the above arrangement, different part limiting plates can be adjusted and replaced according to the size and specifications of the metal parts, so that the ferrule curing tooling can support and limit different metal parts.
[0010] Furthermore, a plurality of heat-insulating support plates of different sizes are detachably mounted on a side of the ferrule limiting plate away from the first limiting groove.
[0011] Through the above arrangement, the heat-insulating support plate can provide heat-insulating support for the tail of the optical fiber, thereby preventing contact between the optical fibers and causing optical fiber adhesion.
[0012] Furthermore, a side of the heat-insulating support plate away from the first limiting groove is located outside the range of the edge of the core insert limiting plate.
[0013] Through the above arrangement, the heat-insulating support plate can support the tail of the optical fiber, thereby preventing the tail of the optical fiber from contacting the heated ferrule limiting plate and preventing several optical fibers from being adhered to each other due to heat.
[0014] Furthermore, the first limiting groove and the second limiting groove are opposite to each other.
[0015] Through the above arrangement, after the ceramic ferrule and the metal parts are placed on the ferrule curing tooling, the ceramic ferrule and the metal parts are regularly arranged under the restriction of the second limiting groove and the first limiting groove, so that the arrangement of the optical fiber is also more regular and the optical fiber is less likely to be entangled and bent.
[0016] Furthermore, the longitudinal cross-section profile of the second limiting groove is V-shaped or an inverted trapezoid.
[0017] Through the above arrangement, the inner wall of the second limiting groove can offset the stable limiting of the metal part, so that the installation support of the metal part is stable.
[0018] Furthermore, the ferrule limiting plate is provided with a first embedding groove for embedding and installing the lower side of the part limiting plate, and the side of the metal part close to the ceramic ferrule can be against or opposite to the vertical side wall of the first embedding groove.
[0019] Through the above arrangement, the provision of the first embedding groove can reduce the installation height of the component limiting plate, making it easier for the component limiting plate to be stably fitted onto the ferrule limiting plate, thereby making the installation of the ferrule limiting plate more stable.
[0020] Furthermore, the center of the inscribed circle of the longitudinal section profile of the second limiting groove may be located on the same horizontal line as the center of the inscribed circle of the longitudinal section profile of the first limiting groove.
[0021] Through the above arrangement, the relativity between the second limiting groove and the first limiting groove can be improved, and the coaxiality of the ceramic ferrule and the metal part during installation and limiting can be improved, so that the coaxiality of the optical fiber and the ceramic ferrule can be better during the ferrule curing process.
[0022] Furthermore, the longitudinal cross-sectional profile of the part limiting plate is "L"-shaped, and the second limiting groove is horizontally provided at the upper end of the part limiting plate.
[0023] Through the above arrangement, the second limiting groove is more easily set to penetrate the upper side of the part limiting plate, and the second limiting groove is also more easily coaxially opposite to the first limiting groove.
[0024] Furthermore, a second embedding groove for embedding and installing the heat insulation support plate is provided on the core limiting plate, and the upper surface of the heat insulation support plate can be coplanar with the upper surface of the lower end of the part limiting plate.
[0025] Through the above arrangement, the heat insulation support plate can be more easily embedded and stably installed on the core insert limiting plate, so that the cooperation between the heat insulation support plate and the core insert limiting plate is smoother, more beautiful and more stable.

DETAILED DESCRIPTION
[0029] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.
[0030] The embodiment is basically as shown in the attached Figure 1 As shown:
[0031] This embodiment is basically as Figure 1 and Figure 2 As shown, an embodiment of the present invention proposes a core insert curing tool, including a core insert limiting plate 10, a part limiting plate 20 and several heat-insulating support plates 30 of different sizes. The heat-insulating support plate 30 is made of red bakelite, and the part limiting plate 20 and the core insert limiting plate 10 are made of 4Cr13 / S136.
[0032] like Figure 1 As shown, the ferrule limiting plate 10 is arranged horizontally, and the longitudinal cross-sectional profile of the ferrule limiting plate 10 is stepped. A plurality of first limiting grooves 101 for limiting the single ceramic ferrules 40 are horizontally arranged on the right front side of the ferrule limiting plate 10. The first limiting grooves 101 horizontally penetrate the top layer of the ferrule limiting plate 10.
[0033] like Figure 1 As shown, the part limiting plate 20 is horizontally detachably mounted on the core limiting plate 10, and the core limiting plate 10 is provided with a first embedding groove 102 for embedding and installing the lower side of the part limiting plate 20. A first mounting hole 202 detachably connected to the core limiting plate 10 is vertically provided at the middle of the part limiting plate 20, and a plurality of second limiting grooves 201 for limiting the single metal part 402 are provided on the part limiting plate 20. The longitudinal section profile of the second limiting groove 201 is "V" shape, the first limiting groove 101 and the second limiting groove 201 are opposite to each other, and the first limiting groove 101 and the second limiting groove 201 are opposite to each other. After the metal part 402 is installed in the second limiting groove 201, the right front side of the metal part 402 can be against or opposite to the vertical side wall of the first embedding groove 102. At the same time, the inscribed center of the longitudinal section profile of the second limiting groove 201 can be on the same horizontal line as the inscribed center of the longitudinal section profile of the first limiting groove 101.
[0034] like Figure 1 As shown, the insert limiting plate 10 is provided with a second embedding groove 103 for the thermal insulation support plate 30 to be embedded and installed. The upper surface of the thermal insulation support plate 30 can be coplanar with the upper surface of the lower end of the part limiting plate 20. A second mounting hole 301 detachably connected to the insert limiting plate 10 is vertically provided on the upper surface of the thermal insulation support plate 30. The left front side of the thermal insulation support plate 30 is located outside the range of the edge of the insert limiting plate 10.
[0035] In addition, if Figure 1 As shown, the longitudinal section profile of the part limiting plate 20 is “L”-shaped, and the second limiting groove 201 is horizontally penetrated and arranged at the upper end of the part limiting plate 20 .
[0036] When the core insert curing tool in this embodiment is used, Figure 2The ceramic ferrule 40, optical fiber 401, metal part 402 and capillary 403 shown are assembled and installed on the ferrule curing tool, so that several groups of optical fiber ferrules are installed one by one in the first limiting groove 101 and the second limiting groove 201. The ceramic ferrule 40 is horizontally embedded in the first limiting groove 101, and the metal part 402 is placed on the second limiting groove 201. The "V"-shaped second limiting groove 201 can stably abut against the side wall of the metal part 402, and the side wall of the first embedding groove 102 can limit the end of the metal part 402, so that the metal part 402 of the optical fiber 401 is stably supported, preventing the long optical fiber 401 from shaking left and right, and also ensuring the stability of the ceramic ferrule 40 and the first limiting groove 101.
[0037] When the end of the optical fiber 401 and the ceramic ferrule 40 are baked and cured, the ferrule limiting plate 10 can limit the left and right movement of the ceramic ferrule 40, and the metal part 402 can also prevent the optical fiber 401 from shaking left and right, thereby preventing the optical fiber 401 from sticking; the metal part 402 can also cooperate with the part limiting plate 20 to support the tail of the optical fiber 401, thereby preventing the tail of the optical fiber 401 from interfering with other components and being pressed and bent; at the same time, the capillary 403 on the optical fiber 401 can support and insulate the optical fiber 401. When the capillary 403 and the tail of the optical fiber 401 contact the insulation support plate 30, the insulation support plate 30 can insulate the capillary 403 and the optical fiber 401, thereby preventing contact between the optical fibers 401 and causing the optical fibers 401 to stick.
