Description

Technical Field

[0001] The invention relates to a photoelectric detector installation structure. Background Art

[0002] The principle of photodetectors is that radiation causes the conductivity of the irradiated material to change. Photodetectors are widely used in various fields of military and national economy. In the visible light or near-infrared band, they are mainly used for ray measurement and detection, industrial automatic control, photometry, etc.; in the infrared band, they are mainly used for missile guidance, infrared thermal imaging, infrared remote sensing, etc. Another application of photoconductors is to use them as camera tube targets. In order to avoid image blur caused by the diffusion of photogenerated carriers, high-resistance polycrystalline materials such as PbS-PbO, Sb2S3, etc. are used for continuous thin film targets. Other materials can be inlaid with the target surface, and the entire target surface is composed of about 100,000 individual detectors. When strong light irradiates the detector for a long time, the detector reaches saturation, the output value is non-linear, the detector generates heat with a large current for a long time, and the detector is burned. Therefore, it is very necessary to design a quick assembly installation structure for photodetectors under strong light conditions. Summary of the invention

The photoelectric detector installation structure of the present invention realizes the rapid installation of the photoelectric detector and the upper seat plate by rotating the mounting sleeve, and after the photoelectric detector moves down, the metal ball is against the groove, the spring is compressed and bent, so that the metal ball can be firmly against the groove, thereby ensuring conduction. The photoelectric detector installation structure of the present invention has a simple and convenient installation method and a good conduction effect. The spring bending is not prone to fatigue failure and can remain effective for a long time.
