Description

Technical Field

[0001] This utility model relates to the field of TO-CAN communication laser manufacturing technology, specifically to an AF two-dimensional tube socket measuring fixture. Background Technology

[0002] TO (Transistor Outline) refers to the transistor's external shape. Early transistors mostly used coaxial packaging, which was later adopted in optical communication and called TO packaging, or coaxial packaging. Coaxial means that the center lines of each optical path, from the laser and lens to the optical fiber, are on the same straight line. Therefore, optical components with TO packaging are also called coaxial packages.

[0003] Currently, coaxial devices dominate the mainstream optical device market due to their ease of manufacturing and cost advantages. TO38, TO46, and TO56 represent the diameter of the TO socket (3.8mm, 4.6mm, and 5.6mm respectively), and these three sizes are commonly used in optical communication. The TO socket provides the mechanical basis for mounting semiconductor laser diodes or simple circuits and other electronic and optical components, while also providing electrical signals to the packaged components through leads and chip placement. Changes in position can lead to device malfunction. Therefore, during production, AF two-dimensional socket measuring fixtures are used to measure the component's position. Two-dimensional measurement ensures compliance with TO packaging process requirements, improving the quality of laser diodes. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the aforementioned shortcomings of existing technologies, this invention provides an AF two-dimensional tube socket measuring fixture, which effectively solves the problem that in existing technologies, electrical signals are provided to packaged components through lead wires and chip mounting positions, and changes in these positions may cause the entire device to malfunction.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides an AF two-dimensional tube socket measuring fixture, comprising:

[0009] The jig body is made of aluminum alloy material;

[0010] A through hole is located in the middle of the fixture body;

[0011] The surface of the through hole is provided with uneven parts.

[0012] Furthermore, the through holes adopt a double-row design, with each row of PCS holes enabling simultaneous fixing and testing of the PCS components to be tested.

[0013] Furthermore, the concave and convex portions are fastened to the concave and convex portions on the tube seat by interlocking with each other.

[0014] Furthermore, the height of the fixture body is the same as the height of the tube seat pin.

[0015] Beneficial effects

[0016] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0017] The fixture body of this utility model is made of imported A6061 aluminum alloy material and undergoes anodizing black process. It has no tendency to stress corrosion cracking and has excellent corrosion resistance. There is no need to worry about measurement errors caused by corrosion and wear of the fixture body.

[0018] The through holes of this utility model adopt a double-row design with 10 holes in each row, which can fix and test 20 components to be tested at the same time, greatly improving production efficiency.

[0019] This invention uses the interlocking of the concave and convex parts on the through hole and the concave and convex parts on the tube seat to make its structure firm and effectively fit the tube seat to be measured. The center of the tube seat and the center of each through hole on the fixture body are kept in the same position.

[0020] This invention inserts the tube pin of the tube seat to be tested into the through hole. The height of the fixture body fully meets the height of the tube pin, thus avoiding the tube seat being out of center of the through hole or not being placed flat due to the height of the tube pin, which would affect the measurement accuracy.
