Description

Technical Field

[0001] The present application relates to the field of photoelectric detector testing technology, and in particular to a photoelectric detector fixture. 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 are used for continuous thin film targets.

[0003] Photodetectors are the most basic receiving devices in optical communication systems. Since different types of materials have different spectral selection characteristics, their parameter performance directly determines the various indicators of the entire optical communication system to a large extent. Therefore, the detector spectral response test is of great significance to the production, detection, application, development and research of the detector.

[0040] The following is combined with Figure 1-4 This application is described in further detail.

[0041] The present application embodiment discloses a photoelectric detector fixture, referring to Figure 1 and Figure 2 The photodetector fixture includes a support frame 2, a top plate 3, a wiring terminal 1, a first clamping mechanism 4 and a second clamping mechanism 5. The top plate 3 is connected to the top of the support frame 2. The first clamping mechanism 4 and the second clamping mechanism 5 are both installed on the top plate 3 for clamping the electrode pins of the photodetector. The second clamping mechanism 5 can press the photodetector without packaging onto the top plate 3. Two wiring terminals 1 are provided, and the two wiring terminals 1 are installed on the top plate 3. The wiring terminals 1 are electrically connected to the photodetector.

[0042] The device can clamp different types of photodetectors, that is, when clamping a packaged photodetector, the first clamping mechanism 4 is used to clamp the electrode pins of the photodetector, and then the photodetector is electrically connected to the two wiring terminals 1 respectively, so that the test can be carried out. When clamping an unpackaged photodetector, the second clamping mechanism 5 can be directly used to fix it. In this way, the device can be applied to both packaged photodetectors and unpackaged photodetectors, thereby improving the versatility of the clamp.

[0043] Specifically, refer to Figure 1 and Figure 2 The support frame 2 includes a bottom plate 21 and a plurality of support columns 22, and the plurality of support columns 22 are connected between the bottom plate 21 and the top plate 3. In this embodiment, four support columns 22 are provided, and the four support columns 22 are arranged in a rectangular shape. Under the action of the support columns 22, the top plate 3 is at a certain distance from the mounting surface, which is convenient for fixing the photoelectric detector and can also ensure stability. The support columns 22 are detachably connected to the top plate 3 and the bottom plate 21, and the detachable connection method can be bolt connection, snap connection, etc., to facilitate assembly and disassembly.

[0044] A through groove 6 capable of accommodating the first clamping mechanism 4 is provided on the top plate 3, and the first clamping mechanism 4 is embedded in the through groove 6. Specifically, the first clamping mechanism 4 includes four clamping components 41, and the four clamping components 41 are divided into two groups. The two clamping components 41 in each group are arranged opposite to each other, and there is a gap between the two groups of clamping components 41. The two groups of clamping components 41 can just fit with the two electrode pins, that is, the two groups of clamping components 41 clamp the two electrode pins respectively to ensure the stability of the clamping. At the same time, since the first clamping mechanism 4 is divided into two parts, the horizontal length can be maximized, which can meet the needs of photoelectric detectors with different electrode pin spacings and improve the scope of application.

[0045] Further, refer to Figure 3 and Figure 4 The clamping assembly 41 includes a spring plate seat 411 and a wire pressing spring plate 412. The spring plate seat 411 is mounted on the top plate 3, and the wire pressing spring plate 412 is mounted on the side of the spring plate seat 411 away from the top plate 3, that is, the two wire pressing spring plates 412 are arranged opposite to each other. When the electrode pin of the photodetector is inserted between the two wire pressing spring plates 412, due to the elasticity of the two wire pressing spring plates 412, the electrode pin of the photodetector can be clamped together to achieve fixation.

[0046] Reference Figure 2 and Figure 3 In order to further improve flexibility, the clamping assembly 41 also includes a fixing screw 413, and the wire pressing spring 412 is connected to the spring seat 411 through the fixing screw 413. By adjusting the fixing screw 413, the distance between the two wire pressing springs 412 in each group can be adjusted to achieve the clamping of electrode pins of different diameters, thereby improving practicality and adaptability.

[0047] Of course, in this embodiment, the spring seat 411 and the top plate 3 are preferably detachably connected to facilitate the assembly and replacement of the spring seat 411. At the same time, the upper surface of the spring seat 411 is flush with the upper surface of the top plate 3, so that the upper surface of the top plate 3 can be ensured to be in a horizontal state. When the photoelectric detector is placed on the top plate 3, it is ensured that the photoelectric detector can be in a horizontal state, which is convenient for the second clamping mechanism 5 to be pressed.

[0048] Reference Figure 2 and Figure 3The second clamping mechanism 5 includes a pressing sheet 51, which is mounted on the top plate 3. The photodetector is placed on the top plate 3, and the pressing sheet 51 is rotated and lifted to fix the photodetector. Of course, in this embodiment, the pressing sheet 51 is made of elastic material to ensure the best pressing effect.

[0049] The second clamping mechanism 5 further includes an adjusting screw 52, ​​through which the pressing piece 51 is connected to the top plate 3. On the one hand, the pressing piece 51 can be detachably connected, and on the other hand, the tightness of the pressing piece 51 can be adjusted to adapt to photoelectric detectors of different sizes.

[0050] In this embodiment, two second clamping mechanisms 5 are provided, and the two second mechanisms are respectively located on both sides of the through slot 6. When the photodetector is placed on the top plate 3, the two second mechanisms respectively press and fix the photodetector and are located on both sides of the photodetector, which can improve stability.

[0051] Of course, in this embodiment, the connection terminal 1 and the top plate 3 are preferably detachably connected, and the detachable connection method is not limited. This facilitates the assembly, disassembly and replacement of the connection terminal 1.

[0052] The implementation principle of a photodetector clamp in an embodiment of the present application is as follows: when clamping a photodetector with a package, adjust the fixing screw 413 according to the diameter of the electrode pin to change the spacing between the two pressing wire springs 412, and use the pressing wire springs 412 to clamp the two electrode pins respectively, and then electrically connect them to the two wiring terminals 1 respectively. After completing the above operations, detection can be carried out. When clamping a photodetector without a package, place the photodetector on a table, press and fix it with two pressing sheets 51 respectively, and then electrically connect it to the two wiring terminals 1. After completing the above operations, detection can be carried out. In this way, the device can be applied to both packaged photodetectors and unpackaged photodetectors, thereby improving the versatility of the clamp.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
