Description

Technical Field

[0001] This utility model relates to a tooling for installing fiber optic ceramic ferrules, and more specifically, it relates to a tooling for simplifying the ceramic ferrule installation process and improving the quality of finished products. Background Technology

[0002] Ceramic ferrules, also known as fiber optic ceramic ferrules, are a type of fiber optic connector that makes the connection, conversion, and scheduling of optical channels more flexible, and facilitates the debugging and maintenance of optical communication systems.

[0003] Currently, fiber optic ceramic ferrules are generally installed manually or with simple clamps. This installation method has the following disadvantages: insufficient precision in the ferrule installation position, causing the ferrule to tilt and affecting subsequent use; excessive force causing indentations on the ferrule surface; and lack of compensation mechanism, resulting in a significant decrease in positioning accuracy during continuous operation. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tooling for simplifying the installation process of ceramic pins and improving the quality of finished products.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tooling for installing fiber optic ceramic ferrules, comprising a ferrule positioning tooling and a base tooling. The ferrule positioning tooling is cylindrical and is used to fix the tail shank of the fiber optic ceramic ferrule. The base tooling is cylindrical and has a groove for placing the ferrule positioning tooling. The bottom outer side of the ferrule positioning tooling has a pair of notches. A pair of elastic clips matching the position and shape of the notches are fixed in the cylindrical groove of the base tooling. The thickness of the elastic clips is between 0.5mm and 2mm.

[0006] By adopting the above technical solution, the tooling of the utility model includes a pin positioning tooling and a base tooling. The pin positioning tooling is annular in shape, and its internal space is used to accommodate the tail shank of the fixed fiber optic ceramic pin. The base tooling has a groove for placing the pin positioning tooling. The pin positioning tooling matches the elastic clip inside the base tooling through a notch on the outside, so that the base tooling and the pin positioning tooling will not shift or slide when the ceramic pin is installed. The thickness of the elastic clip is set within a certain range. When the thickness is less than 0.5mm, the relative size of the elastic clip is insufficient and the anti-slip effect is not obvious. When the thickness is greater than 2mm, the friction between the two toolings will be too large, making disassembly inconvenient. At the same time, it will also cause the notch on the pin positioning tooling to be too large, resulting in insufficient structural strength of the lower half of the pin positioning tooling.

[0007] The present invention is further configured such that: the elastic clip includes a block fixed inside the groove and an anti-slip sleeve fitted on the block, and the block has several strip-shaped protrusions on the side in contact with the anti-slip sleeve.

[0008] By adopting the above technical solution, the elastic clip includes a block located inside the groove and an anti-slip sleeve fitted on the block. When the pin positioning fixture is placed in the base fixture, the anti-slip sleeve will be clamped between the block and the pin positioning fixture. The anti-slip sleeve has a large coefficient of friction, which effectively prevents the pin positioning fixture from shifting on the base fixture. The block is also provided with several strip-shaped protrusions. These strip-shaped protrusions are located at the position where the block surface engages with the anti-slip sleeve, which can effectively prevent the sleeve from falling off the block during use.

[0009] The present invention is further configured such that: the bottom of the base fixture is provided with an anti-displacement structure, the anti-displacement mechanism including a vacuum adsorption hole and an anti-slip rubber pad.

[0010] By adopting the above technical solution, the bottom of the base fixture is provided with an anti-deviation mechanism, which includes a vacuum adsorption hole and an anti-slip rubber pad. The anti-deviation mechanism can effectively prevent the base fixture from slipping and shifting on the worktable. The vacuum adsorption hole can provide a stable adsorption force for the base to work through vacuum adsorption, and the anti-slip rubber pad increases the friction coefficient between the bottom fixture and the worktable. Overall, the bottom fixture is less likely to slip, thus improving the overall stability.

[0011] The present invention is further configured such that the ratio of the inner diameter to the outer diameter of the base fixture is between 2 / 3 and 5 / 7.

[0012] By adopting the above technical solution, the ratio of the inner diameter to the outer diameter of the base fixture is controlled between 2 / 3 and 5 / 7. When the ratio is less than 2 / 3, the volume of the base fixture will be too large relative to the pin positioning fixture, which will increase unnecessary material costs. When the ratio is greater than 5 / 7, the inner diameter of the groove of the base fixture will be close to the outer diameter of the base fixture, making the groove wall relatively insufficient for the pin positioning fixture, thus weakening the support and fixing ability of the base fixture for the pin positioning fixture.

[0013] The present invention is further configured such that: the outer side of the pin positioning fixture and the part that fits with the base fixture are provided with a composite coating, the composite coating being made of molybdenum dioxide and epoxy resin in a ratio of 1:5 to 1:3.

[0014] By adopting the above technical solution, the outer part of the pin positioning fixture is coated with a composite coating. This coating is made of molybdenum dioxide and epoxy resin in a ratio of 1:5 to 1:3. This composite coating can achieve maintenance-free lubrication of the fixture and reduce the risk of jamming when removing the ceramic pin after installation.

[0015] The present invention is further configured such that the surface of the pin positioning fixture is coated with an insulating protective layer.

[0016] By adopting the above technical solution, the insulating protective layer coated on the surface of the pin positioning fixture plays a role in electrostatic protection. When using this fixture for automated production, it can effectively prevent the accumulation of static voltage and avoid generating electric sparks that could cause fires and damage the fixture and other equipment.

[0017] The present invention is further configured such that the pin positioning fixture and the base fixture are made of carbon steel, alloy steel or stainless steel.

[0018] By adopting the above technical solution, the pin positioning fixture and the base fixture are made of common materials such as carbon steel, alloy steel or stainless steel. Since these two types of fixtures are used to install ceramic pins, rigid materials should be given priority in manufacturing. Carbon steel has higher strength and hardness than stainless steel, but it is prone to rust. Alloy steel has additional alloys added to the original composition of carbon steel, which improves its strength and corrosion resistance. However, in actual manufacturing, the choice of material should be determined based on the actual situation due to the different sources of raw materials and cost issues. Attached Figure Description

[0024] Reference Figures 1 to 4 The following is a further description of an embodiment of the sealing structure of this utility model for cables.

[0025] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0026] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0027] A fixture for installing fiber optic ceramic ferrules includes a ferrule positioning fixture 1 and a base fixture 2. The ferrule positioning fixture 1 is cylindrical and is used to fix the tail shank of the fiber optic ceramic ferrule. The base fixture 2 is cylindrical and has a groove 3 for placing the ferrule positioning fixture 1. The bottom outer side of the ferrule positioning fixture 1 has a pair of notches 4. A pair of elastic clips 5 that match the position and shape of the notches 4 are fixed in the cylindrical groove 3 of the base fixture 2. The thickness of the elastic clips 5 is between 0.5 mm and 2 mm. By adopting the above technical solution, the tooling of the utility model includes a pin positioning tooling 1 and a base tooling 2. The pin positioning tooling 1 is an annular cylindrical shape, and its internal space is used to accommodate the tail shank of the fixed fiber optic ceramic pin. The base tooling 2 is provided with a groove 3 for placing the pin positioning tooling 1. The pin positioning tooling 1 matches the elastic clip 5 inside the base tooling 2 through the notch 4 set on the outside, so that there will be no offset or sliding between the base tooling 2 and the pin positioning tooling 1 when installing the ceramic pin. The thickness of the elastic clip 5 is set within a certain range. When the thickness is less than 0.5mm, the relative size of the elastic clip 5 is insufficient and the anti-slip effect is not obvious. When the thickness is greater than 2mm, the friction between the two toolings will be too large, making it inconvenient to disassemble. At the same time, it will also cause the notch 4 on the pin positioning tooling 1 to be too large, resulting in insufficient structural strength of the lower half of the pin positioning tooling 1.

[0028] Furthermore, the elastic clip 5 includes a block 6 fixed inside the groove 3 and an anti-slip sleeve 7 fitted onto the block 6. The block 6 has several strip-shaped protrusions 8 on the side that contacts the anti-slip sleeve 7. By adopting the above technical solution, the elastic clip 5 includes a block 6 located inside the groove 3 and an anti-slip sleeve 7 fitted onto the block 6. When the pin positioning fixture 1 is placed in the base fixture 2, the anti-slip sleeve 7 will be clamped between the block 6 and the pin positioning fixture 1. The anti-slip sleeve 7 has a large coefficient of friction, which effectively prevents the pin positioning fixture 1 from shifting on the base fixture 2. The block 6 also has several strip-shaped protrusions 8, which are located at the position where the anti-slip sleeve 7 fits on the surface of the block 6, which can effectively prevent the sleeve from falling off the block 6 during use.

[0029] Furthermore, the bottom of the base fixture 2 is also provided with an anti-displacement structure, which includes a vacuum adsorption hole 9 and an anti-slip rubber pad 10. By adopting the above technical solution, the bottom of the base fixture 2 is provided with an anti-displacement mechanism, which includes a vacuum adsorption hole 9 and an anti-slip rubber pad 10. This anti-displacement mechanism can effectively prevent the base fixture 2 from slipping and shifting on the worktable. The vacuum adsorption hole 9 can provide a stable adsorption force for the base to work through vacuum adsorption, while the anti-slip rubber pad 10 increases the coefficient of friction between the bottom fixture and the worktable. Overall, the bottom fixture is less likely to slip, thus improving the overall stability.

[0030] Furthermore, the ratio of the inner diameter to the outer diameter of the base fixture 2 is between 2 / 3 and 5 / 7. By adopting the above technical solution, the ratio of the inner diameter to the outer diameter of the base fixture 2 is controlled between 2 / 3 and 5 / 7. When this ratio is less than 2 / 3, the volume of the base fixture 2 will be too large relative to the pin positioning fixture 1, which will increase unnecessary material costs. When this ratio is greater than 5 / 7, the inner diameter of the groove 3 of the base fixture 2 will be close to the outer diameter of the base fixture 2, making the groove wall of the groove 3 relatively insufficient for the pin positioning fixture 1, thus weakening the support and fixing ability of the base fixture 2 for the pin positioning fixture 1.

[0031] Furthermore, the outer side of the pin positioning fixture 1, which is in contact with the base fixture 2, is coated with a composite coating. This composite coating is made of molybdenum dioxide and epoxy resin in a ratio of 1:5 to 1:3. By adopting the above technical solution, the outer side of the pin positioning fixture 1 is coated with a composite coating made of molybdenum dioxide and epoxy resin in a ratio of 1:5 to 1:3. This composite coating enables maintenance-free lubrication of the fixture, reducing the risk of jamming when removing the ceramic pin after installation.

[0032] Furthermore, the surface of the pin positioning fixture 1 is coated with an insulating protective layer. By adopting the above technical solution, the insulating protective layer coated on the surface of the pin positioning fixture 1 plays a role in electrostatic protection. When using this fixture for automated production, it can effectively prevent the accumulation of static voltage, avoid the generation of electric sparks that could cause fires, and prevent damage to the fixture and other equipment.

By adopting the above technical solution, the pin positioning fixture 1 and the base fixture 2 are made of common materials such as carbon steel, alloy steel, or stainless steel. Since these two fixtures are used to install ceramic pins, rigid materials should be prioritized during manufacturing. Carbon steel has higher strength and hardness than stainless steel, but it is prone to rust. Alloy steel, on the other hand, has additional alloys added to the original composition of carbon steel, improving both strength and corrosion resistance. However, in actual manufacturing, the choice of material depends on the specific circumstances, considering the different sources of raw materials and cost issues.
