Description

Technical Field

[0001] This utility model relates to the field of optical fiber connection technology in optical communication, and specifically to an optical module optical interface assembly device. Background Technology

[0002] With the rapid development of fiber optic communication technology, big data, and artificial intelligence (AI), society's demand for data transmission is increasing. This trend is driving the continuous improvement of optical module transmission rates, while also placing stringent requirements on the entire optical path system for low loss and high stability.

[0003] The optical interface (receptacle end) of an optical module carries the tasks of storing, processing, and transmitting massive amounts of data, and has become an important support for information exchange and transformation in various industries. At the same time, in order to adapt to the technological upgrade direction of optical modules, the optical interface also needs to meet multiple requirements such as higher density connector assembly, miniaturized design of optical modules, and high-speed transmission.

[0004] Optical modules typically consist of an external metal component, a ceramic sleeve, and a ferrule. Tools are required to assemble these components. However, current assembly methods place the ferrule at the bottom, the external metal component and ceramic sleeve at the top, and then use tools to press the external metal component down. This process cannot guarantee the concentricity of the ferrule and the external metal component, resulting in significant deviations between the metal component and the ceramic sleeve's center. This leads to substantial fluctuations in four-way insertion loss (IL), uneven insertion and extraction force distribution, and excessive concentricity in the finished product, resulting in low product quality. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an optical module and optical interface assembly device, which aims to improve the quality of finished optical interfaces.

After the locking bolt passes through the locking bolt hole, the inner end of the locking bolt is pressed against the outer peripheral surface of the probe fixing fixture.

[0014] According to the above scheme, the base assembly includes a limiting clamp and a clamp base. The limiting clamp is fixed to the top of the clamp base. The limiting clamp has a limiting groove that is adapted to the outer periphery of the pressing lower clamp. The pressing lower clamp is installed on the top of the clamp base, and the outer periphery of the pressing lower clamp is in contact with the groove wall of the limiting groove.

The ceramic sleeve 13-3 is open at both ends and is assembled inside the external metal part 13-4, serving as a key connection component. The ferrule 13-2 houses an optical fiber 13-5. The upper end of 13-2 needs to be inserted into the ceramic sleeve 13-3. The lower end of the ferrule 13-2 is fixed with the collar 13-1. The collar 13-1 is assembled into the external metal part 13-4, and the upper end face of the collar 13-1 abuts against the lower end face of the ceramic sleeve 13-3. The optical fiber 13-5 is led out from the lower end of the ferrule 13-2. To ensure sealing and connection firmness, the lower ends of the ferrule 13-2 and the external metal part 13-4 are encapsulated with adhesive layer 13-6.

[0035] This utility model is used for the assembly of the ferrule 13-2 (configured with optical fiber 13-5 and collar 13-1), ceramic sleeve 13-3 and external metal part 13-4, to ensure that each component is precisely matched and meets the requirements of the component.

[0036] Example 1 like Figures 2-3The optical module optical interface assembly device shown includes a crimping clamp assembly, a base assembly, and a pressing assembly; The base assembly is placed on the workbench; The crimping clamp assembly includes a lower crimping clamp 4 and an upper crimping clamp 5. The lower crimping clamp 4 is fixed on the base assembly, and the upper crimping clamp 5 is arranged opposite to the lower crimping clamp 4 and the two are connected by a guide mechanism. The upper inner part of the upper crimping clamp 5 is provided with an upper crimping hole that is adapted to the external metal part 13-4 of the optical interface 13, and the lower inner part of the upper crimping clamp 5 is provided with a lower crimping hole that is adapted to the ferrule of the optical interface 13. The upper crimping hole and the lower crimping hole are coaxial and connected. The pressing clamp 4 is provided with a tightening boss 16 that is adapted to the pressing hole, and the upper end of the tightening boss 16 is inserted into the pressing hole. The pressing component is positioned directly above the pressing clamp 5, and the pressing component drives the pressing clamp 5 to move vertically downward.

[0037] In this utility model, the lower end of the external metal part 13-4 of the optical interface 13 is inserted into the upper pressing hole of the upper clamping fixture 5. The upper end of the external metal part 13-4 is directly opposite the driving end of the lower pressing assembly. The lower pressing assembly can drive the external metal part 13-4 and the upper clamping fixture 5 to move vertically downward. The insert 13-2 of the optical interface 13, which is fitted with a ceramic sleeve 13-3, is located in the lower pressing hole of the upper clamping fixture 5. The upper end of the tightening boss 16 is inserted into the lower pressing hole and can contact the end face of the collar 13-1 at the lower end of the insert 13-2.

[0038] In this utility model, such as Figure 6 As shown, the lower clamping fixture 4 is fixed on the base assembly, and its clamping boss 16 is inserted into the lower pressing hole of the upper clamping fixture 5 (the clamping boss 16 is coaxial with the lower pressing hole), and the upper end of the clamping boss 16 can contact the end face of the collar 13-1 at the lower end of the insert 13-2; an external metal part 13-4 is installed in the upper pressing hole of the upper clamping fixture 5, and the lower end of the external metal part 13-4 is fitted onto the upper end of the ceramic sleeve 13-3; the lower pressing assembly presses down on the upper part of the external metal part 13-4. When the end is reached, the external metal part 13-4 drives the upper clamping fixture 5 to move downward, and the gap between the upper clamping fixture 5 and the lower clamping fixture 4 becomes smaller. At this time, the insert 13-2 and the collar 13-1 located in the lower pressing hole enter the external metal part 13-4 under the pressing action of the pressing boss 16. The upper part of the insert 13-2 is assembled with the lower part of the ceramic sleeve 13-3, and the upper part of the ceramic sleeve 13-3 is assembled with the external metal part 13-4, thus realizing the assembly of the optical interface 13.

Three sets of guiding mechanisms are provided, arranged in an equilateral triangle. This arrangement ensures that the upper clamp 5 is pressed vertically downward under the action of the guiding mechanisms, further improving the concentricity of the optical interface 13 assembly.

[0041] Preferably, such as Figure 3 As shown, a vertical ejector groove is provided in the upper clamping fixture 5, and an ejector pin 6 is installed in the ejector groove. The lower end of the ejector pin 6 is sleeved with an ejector pin spring 14.

A pin spring 14 is sleeved at the lower end of the pin 6, and the pin spring 14 is disposed inside the spring fixing sleeve 10, which is installed in the spring groove below the pin groove. When the pressing assembly drives the external metal part 13-4 to press down, the pin 6 located below the annular boss 13-4-1 compresses the pin spring 14 downwards. After the external metal part 13-4 is assembled with the insert 13-2 and the ceramic sleeve 13-3, the pressing assembly is raised, the pin spring 14 is reset, and the pin 6 pushes the external metal part 13-4 out of the upper pressing hole of the pressing clamp 5 under the action of the pin spring 14, making it convenient for the operator to pick it up.

[0043] Preferably, a limiting bolt 11 is further provided between the upper pressing clamp 5 and the lower pressing clamp 4; the upper pressing clamp 5 has a through hole adapted to the limiting bolt 11, the diameter of the through hole being smaller than the outer diameter of the head of the limiting bolt 11; the head of the limiting bolt 11 is located outside the through hole of the upper pressing clamp 5, and the lower end of the limiting bolt 11 passes through the through hole of the upper pressing clamp 5 and is threadedly connected to the lower pressing clamp 4.

[0045] Preferably, the pressing component includes a pressing head 3, the lower end of which is directly opposite the external metal part 13-4 of the optical interface 13; and the pressing head 3 can move downward under the action of the lifting mechanism to press the upper surface of the external metal part 13-4.

[0047] In this utility model, the top of the pressure head 3 is provided with a mounting groove that is compatible with the probe fixing clamp 2, and the probe fixing clamp 2 is located in the mounting groove; the outer sides of the pressure head 3 are respectively provided with radial locking bolt holes 3-1, and the inner end of the locking bolt passes through the locking bolt hole 3-1 and presses against the outer peripheral surface of the probe fixing clamp 2; the lifting mechanism drives the probe fixing clamp 2 and the pressure head 3 to move downward, and the pressure head 3 presses down to press the outer metal part 13-4 of the optical interface 13.

[0049] In this invention, the probe 1 is a ceramic probe 1; the probe 1 is inserted into the probe hole of the probe fixing fixture 2 to ensure that the probe 1 is coaxial with the probe hole (the probe hole is coaxial with the upper pressure hole and the lower pressure hole), and to ensure that the probe 1 moves smoothly and without interference in the probe hole after assembly; when assembling the external metal part 13-4, ceramic sleeve 13-3, and ferrule 13-2 of the optical interface 13, the probe 1 can be used to detect the depth of the ferrule 13-2 extending into the external metal part 13-4 to ensure proper assembly.

[0050] Preferably, such as Figure 2 As shown, the base assembly includes a limiting clamp 9 and a clamp base 12. The limiting clamp 9 is fixed to the top of the clamp base 12 by a fixing screw 15. The limiting clamp 9 has a limiting groove that is adapted to the outer periphery of the pressing lower clamp 4. The pressing lower clamp 4 is installed on the top of the clamp base 12, and the outer periphery of the pressing lower clamp 4 fits against the groove wall of the limiting groove.

[0053] This embodiment describes the assembly of optical interface 13 in a POSA product. The lower end of optical fiber 13-5 of optical interface 13 connects to other accessories; this is not an improvement on the technology described in this application and will not be elaborated upon here. The working process of this embodiment is as follows: Step 1: According to the product type and installation requirements of the optical interface 13, adjust the maximum displacement of the upper clamping fixture 5 relative to the lower clamping fixture 4 by using the limit bolt 11; Step 2: Pass probe 1 through the probe hole of probe fixing fixture 2 to ensure that probe 1 is concentric with ferrule 13-2 of optical interface 13 during measurement; Step 3: The lower end of probe 1 passes through the probe hole of pressure head 3, and pressure head 3 is fixed on probe fixing fixture 2 by locking screw, forming a pressable and measurable structure.

Step 7: The pressing head 3 of the pressing assembly moves downward, driving the external metal part 13-4 and the pressing clamp 5 to press down. The guide spring 7 and the ejector pin spring 14 are compressed. Under the action of the pressing boss 16, the insert 13-2 in the pressing clamp 5 is assembled with the lower end of the ceramic sleeve 13-3. At the same time, the upper end of the ceramic sleeve 13-3 is assembled with the external metal part 13-4.

Step 8: After the crimping is completed, the pressure head 3 moves upward, the guide spring 7 rebounds, the ejector spring 14 resets and pushes the ejector pin 6 upward. The ejector pin 6 then pushes out the assembled optical interface 13, crimps it onto the clamp 5, and removes it. Step 9: Place the assembled optical interface 13 product on the existing concentricity test platform and test the concentricity of the optical interface 13 product.
