[0002] A photodetector is an electronic device that converts light signals into electrical signals. Its core function is to perform photoelectric conversion. It works through the photoelectric effect of semiconductor materials (such as internal photoelectric effect or external photoelectric effect), absorbing photons to generate electron-hole pairs, thereby forming a photocurrent in the external circuit that is proportional to the intensity of the incident light. The applications of photodetectors cover many fields such as military, communications, medical, industrial, environmental, scientific research, consumer electronics and intelligent driving. They are an indispensable sensory nerve of modern technology.

[0003] The existing technical solutions mentioned above have the following drawbacks: When performing internal maintenance on existing photodetectors, some are integrated structures, some have complex disassembly structures, or the interlocking structures between the housings are too tight, making it difficult to perform internal maintenance and repair on the detector.
