Description

Technical Field

[0001] This utility model relates to the field of optoelectronic communication technology, and in particular to a detection fixture for quickly determining the parallelism and angle of the coupling lens of a COB single-channel SFP board core. Background Technology

[0002] SFP (Small Form Pluggable) is a small, hot-swappable optoelectronic transceiver module widely used in telecommunications and data communications. It enables electro-optical conversion between network equipment and fiber optic or copper cables. It can be simply understood as an upgraded version of GBIC (Gigabit Interface Converter), a device that converts gigabit electrical signals to optical signals and is hot-swappable. When producing SFP boards using COB technology using active couplers, a problem arises where the coupled boards experience high insertion and extraction forces after housing installation. This results in high insertion and extraction forces on dual LC jumpers after housing installation, affecting module operation and hindering the current active couplers from effectively detecting module parallelism and filtering out defective products, thus impacting production quality. Summary of the Invention

The light emitting sub-module is connected to the first gauge, and the light receiving sub-module is connected to the second gauge. The base is provided with a reference seat, which is arranged along the length of the base and located between the first gauge and the second gauge.

[0005] Preferably, the reference base is perpendicular to the base body, the reference base and the base body are integrally formed, and a first channel and a second channel are provided at the connection between the reference base and the base body.

Detailed Implementation

[0017] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0018] The present invention will now be described in detail with reference to the accompanying drawings.

[0019] like Figures 1 to 4 As shown, this utility model discloses a detection fixture for quickly determining the parallelism and angle of a COB single-channel SFP core coupled lens. It includes a base 1, an SFP optical assembly 2 disposed on the base 1, and a first guide gauge 3 and a second guide gauge 4 connected to the SFP optical assembly 2. The SFP optical assembly 2 includes a PCB board 21 and a light emitting sub-module 22 and a light receiving sub-module 23 disposed on the PCB board 21. The light emitting sub-module 22 and the light receiving sub-module 23 are spaced apart and arranged parallel to each other. The light emitting sub-module 22 is connected to the first guide gauge 3, and the light receiving sub-module 23 is connected to the second guide gauge 4. The base 1 is provided with a reference seat 13, which is arranged along the length of the base 1 and located between the first guide gauge 3 and the second guide gauge 4.

[0020] During operation, the operator first places the PCB board 21 flat on the base 1, and then inserts the first guide gauge 3 and the second guide gauge 4 into the coupled light emitting sub-module 22 and light receiving sub-module 23, respectively. Since the reference base 13 is located between the first guide gauge 3 and the second guide gauge 4, the operator observes from a top-down angle whether the first guide gauge 3 and the second guide gauge 4 are parallel to the parallel plane of the reference base 13. If they are not parallel, it indicates that the light emitting sub-module 22 and the light receiving sub-module 23 have a horizontal angular tilt. Next, the operator observes from a front-view angle whether the first guide gauge 3 and the second guide gauge 4 are on the same horizontal plane. If they are not parallel, it indicates that the socket of the light emitting sub-module 22 is not parallel to the socket of the light receiving sub-module 23. In addition, the operator continues to observe whether the first guide gauge 3 and the second guide gauge 4 are parallel to the surface of the base 1. If they are not parallel, it indicates that the light emitting sub-module 22 and the light receiving sub-module 23 have a vertical angular tilt. The detection operation is simple and convenient, and the detection efficiency is high. This invention enables effective detection and judgment of module parallelism, quickly screens out defective products, avoids the situation of large insertion and extraction force of double LC jumpers after the shell is installed, ensures stability in use, and improves production quality.

[0021] In this embodiment, the reference base 13 is perpendicular to the base body 1, and the reference base 13 and the base body 1 are integrally formed. A first channel 11 and a second channel 12 are provided at the connection between the reference base 13 and the base body 1. The first channel 11 and the second channel 12 are located on opposite sides of the reference base 13. The first gauge 3 is housed within the first channel 11, and the second gauge 4 is housed within the second channel 12. Specifically, the reference base 13 is perpendicular to the base body 1, and the integral formation of the reference base 13 and the base body 1 results in high structural strength, simplified manufacturing steps, and a high yield rate. When the first gauge 3 and the second gauge 4 are inserted into the coupled optical emission sub-module 22 and optical receiving sub-module 23, respectively, the first gauge 3 is housed within the first channel 11, and the second gauge 4 is housed within the second channel 12. This allows the operator to better observe whether the first gauge 3 and the second gauge 4 are parallel to the parallel surface of the reference base 13, improving the accuracy of judgment.

[0022] In this embodiment, the base 1 is provided with a receiving cavity 14, which is recessed from the surface of the base 1, and the PCB board 21 is housed in the receiving cavity 14. Specifically, the receiving cavity 14 is recessed from the surface of the base 1 and has a square structure, which increases the contact area between the receiving cavity 14 and the PCB board 21 and improves the stability of the PCB board 21.

[0023] In this embodiment, the base 1 is provided with a through groove 15, which penetrates through the middle of the base 1 to connect with the receiving cavity 14. Specifically, the through groove 15 penetrates through the middle of the base 1 to connect with the receiving cavity 14. Based on the through groove 15, the operator can easily pick up and put down the PCB board 21.

[0024] In this embodiment, the base 1 is provided with support columns 16, which protrude from the inner wall of the base 1. Multiple support columns 16 are provided, and these multiple support columns 16 abut against the PCB board 21. Specifically, preferably, four support columns 16 are provided, and all four support columns 16 abut against the PCB board 21, providing stable support around the PCB board 21 and further improving the stability of the PCB board 21 on the base 1.

[0025] In this embodiment, the bottom of the seat 1 is provided with an anti-slip pad 17. Specifically, the anti-slip pad 17 is located at the bottom of the seat 1 and is made of rubber. This arrangement allows the anti-slip pad 17 to contact the tabletop, increasing friction and preventing the seat 1 from sliding.
