[0029] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 as well as Figure 5 The PIN / APD-TIA detector 1 is a device commonly used in optical communications and optical detection applications. During use, the performance of the detector 1 may vary with temperature. In some cases, temperature fluctuations may cause unstable performance.

[0030] At the same time, the performance of the detector 1 may be affected by optical effects, such as reflection, scattering, etc., especially in complex optical environments. Based on this, when using it, it is necessary to try to avoid the above-mentioned phenomena. Therefore, the present application provides a photoelectric detector 1, including a detector body 1, and a matching portion 2 mounted on the detector body 1;

[0031] The middle part of the detector body 1 is provided with a detection part 12 for receiving signals for detection;

[0032] The matching part 2 includes a shell 22 , a light channel 21 is provided on the top of the shell 22 , and a boss 23 is provided on the inner side of the light channel 21 for assembling different lenses to cooperate with the detection part 12 to improve the detection accuracy.

[0033] The detection unit 12 is used to receive signals and perform detection, which ensures that the detector 1 has high sensitivity and accuracy to light signals.

[0034] A light channel 21 is provided at the top of the housing 22, and a boss 23 is provided on the inner side of the light channel 21 for assembling different lenses, allowing the user to select a suitable lens according to specific application requirements and install it on the detector body 1 to customize the optical properties of the detector body 1. By coordinating the lens and the detection part 12, the light can be more accurately focused on the detection part 12 of the detector body 1, thereby improving the accuracy and sensitivity of the detection front end.

[0035] By optimizing the optical design, it is ensured that the light is accurately focused on the detection part 12, thereby improving the accuracy of the detector body 1, enabling it to more accurately capture and analyze optical signals. The selection and installation of the lens can make the detector body 1 have more stable performance under different environmental conditions. Even in the case of complex optical environment or large temperature changes, it can maintain good detection performance. Users can choose different lenses according to specific application requirements to customize the optical properties of the detector body 1, making it more suitable for different optical communication and optical detection scenarios. A simple and easy-to-use matching part 2 is designed, and users can easily replace lenses for rapid customization and adjustment without the need for complicated operating steps or professional knowledge.

[0036] See also Figure 1 、 Figure 2 、 Figure 3 A slot 13 is provided at the top of the detector body 1 on the outside of the detection part 12 , and a positioning ring 14 is provided at the top of the detector body 1 on the outside of the slot 13 for cooperating with the matching part 2 to keep the matching part 2 fixed.

[0037] One or more telescopic members 15 are provided at the top of the detector body 1 between the positioning ring 14 and the locking groove 13 , and the telescopic members 15 are adapted to the matching portion 2 .

[0038] A positioning ring 14 is provided on the outside of the slot 13. The purpose of this design is to cooperate with the matching portion 2 (ie, the housing 22) to ensure that the matching portion 2 can be firmly connected to the detector body 1 and remain stable.

[0039] One or more telescopic members 15 are provided between the positioning ring 14 and the retaining groove 13, and these telescopic members 15 are adapted to the mating portion 2. The telescopic members 15 are used to adjust and secure the mating portion 2 as needed during use of the detector 1. This ensures a tight and reliable connection between the mating portion 2 and the detector body 1, regardless of the environment, and prevents it from loosening or falling off.

[0040] The design of the slot 13 , the positioning ring 14 and the telescopic member 15 ensures that the connection between the fitting portion 2 and the detector body 1 is firm and reliable, and is not easily disturbed or affected by external factors, thereby improving the stability of the entire detector.

[0041] The telescopic member 15 can be used to conveniently adjust the position and fixation of the matching portion 2, making the installation process simpler and faster without the need for additional tools or complicated operating steps.

[0042] Since the retractable telescopic member 15 is designed, the fitting portion 2 can be fine-tuned as needed, thereby reducing damage or wear caused by external impact on the connecting member and extending the service life of the detector.

[0043] The design of the telescopic member 15 enables the detector to adapt to matching parts 2 of different sizes and shapes, thereby enhancing its scope of application and flexibility, making it more versatile and adaptable.

[0044] See also Figure 2 、 Figure 3 A resistance block is provided on the top of the telescopic member 15, and the resistance block is in contact with one side of the filter.

[0045] The telescopic member 15 is one of the common components in the mechanical field, such as a spring telescopic rod, a micro pneumatic rod, etc. From the perspective of use, the micro pneumatic rod is preferably used;

[0046] The design of the resistance block takes into account the protection and stability of the filter. By fitting closely to the side of the filter, it can effectively reduce the gap between the filter and the telescopic member 15, preventing unnecessary vibration and movement. This not only ensures the effectiveness of the filter, but also improves the performance and stability of the entire photodetector 1.

[0047] The fitting design of the resistance block can effectively protect the filter surface from scratches or damage, extend the service life of the filter, and ensure the stability and durability of its optical performance.

[0048] By fitting the abutment block to the filter, looseness and friction between the filter and the telescopic member 15 can be reduced, thereby improving the stability and reliability of the entire component.

[0049] The design of the resistance block makes the installation of the filter easier and faster. No additional support or fixing tools are required, and users can easily fix and adjust the filter.

[0050] By ensuring a close fit between the filter and the telescopic member 15 , the loss and interference of the optical signal can be minimized, and the transmission efficiency and accuracy of the optical system can be improved.

[0051] See also Figure 1 、 Figure 2 、 Figure 3 A sealing ring 24 is provided at the bottom of the housing 22 . The sealing ring 24 is adapted to the positioning ring 14 to maintain the stability of the housing 22 .

[0052] The outer side of the boss 23 is close to the vertical center line of the light channel 21 to form a step, and is combined with the filter area.

[0053] A sealing ring is also provided on the inner side of the boss 23, and the sealing ring is adapted to the filter.

[0054] The sealing ring 24 is adapted to the positioning ring 14, and its function is to ensure that the connection between the outer shell 22 and the detector body 1 is firm and reliable. The design of the sealing ring 24 can not only effectively prevent dust, water vapor and other foreign substances from entering the interior of the detector, but also improve the waterproof performance of the detector and extend its service life.

[0055] The boss 23 is combined with the filter so that the boss 23 can better accommodate the filter assembly, ensuring its stable installation on the detector, while reducing the loss and interference of light during transmission, thereby improving the performance and accuracy of the optical system.

[0056] A sealing ring is also provided on the inner side of the boss 23. This sealing ring is adapted to the filter and its function is to further strengthen the fixation and sealing effect of the filter. The sealing ring can effectively prevent the erosion and damage of the filter by external environmental factors such as dust and moisture, and protect the optical performance and stability of the filter.
