[0002] A sensitive element is a special electronic component that can keenly sense certain physical, chemical, or biological information and convert it into electrical information. These components are typically made using a material's sensitive properties. Sensitive elements can be named according to the physical quantity they input, such as thermistors (see thermistors), photosensors, pressure sensors, magnetic sensors, gas sensors, and humidity sensors. Using sensitive elements in electronic devices to perceive external information can achieve or exceed the capabilities of human sensory organs. Sensitive elements are the core components of sensors. With the rapid development of electronic computers and information technology, the importance of sensitive elements is increasing daily.
[0003] Sensitive components typically have two or three connection pins. The testing process requires connecting these pins to power on the component for testing. However, due to the inconsistent number of pins and the varying lengths of pins of different specifications, traditional testing equipment fixtures require manual wiring of each sensitive component, resulting in very low operational efficiency. Summary of the Invention
[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a fixture for testing the performance of sensitive components, which solves the problem that traditional testing equipment fixtures often require manual wiring one by one when testing sensitive components, which greatly reduces the efficiency of operation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;
[0021] Please refer to Figures 1-4. In this utility model, a performance testing fixture for sensitive elements includes a base 1. A control host 2 is fixedly installed on the top of the base 1. Two parallel guide rods 3 are fixedly installed on one side of the control host 2. Two locking strips 4 are slidably connected to the two guide rods 3. Two support columns 5 are fixedly installed on the base 1. The tops of the two support columns 5 are respectively fixedly connected to the ends of the two guide rods 3. A front pressure plate 6 is fixedly installed between the two support columns 5. The front pressure plate 6 and the locking strips 4 are electrically connected to the control host 2 via a cable tray. Two clamping mechanisms 7 for positioning the locking strips 4 are installed on the control host 2. A main wiring board 8 is fixedly installed between the two guide rods 3. The main wiring board 8 is located between the front pressure plate 6 and the locking strips 4. Semi-circular vertical grooves 9 are opened on both sides of the main wiring board 8. A clamping member 10 is slidably installed at the bottom between the two guide rods 3.
[0022] In this invention, the base 1 serves as the support for the device. First, the two pins of the sensitive element are placed across the clamping strip 4 so that they are inserted into the interior of the vertical slots 9 on both sides. Then, the clamping mechanism 7 is released, and the clamping strip 4 is moved along the guide rod 3 to the front pressure plate 6, so that the pins inside one side of the vertical slot 9 are pressed by the front pressure plate 6. Then, the clamping member 10 is driven to rise, and then the clamping member 10 is moved to the other side of the clamping strip 4 to cooperate with the front pressure plate 6 to clamp the pins of the sensitive element on the clamping strip 4, thereby clamping and fixing the sensitive element. Then, the host 2 is controlled to perform an electrical test on the sensitive element. When there are three pins, the two clamping strips 4 are closed to form three holes in the longitudinal direction, so that the three pins can be inserted. Then, the above operation is repeated for positioning and electrical testing. This device has the advantages of flexible clamping structure switching for different numbers of pins, making the operation more flexible and efficient. It solves the problem in the prior art that due to the inconsistent number of pins and the different lengths of pins of different specifications, traditional testing equipment fixtures need to manually connect wires one by one when testing sensitive elements, resulting in very low operating efficiency.
[0023] Please refer to Figure 2, in which: the clamping mechanism 7 includes a sliding post 71, a clamping block 72 and a spring 73. One end of the sliding post 71 is slidably connected to the control host 2, and the other end of the sliding post 71 passes through and is slidably connected to one side of the clamping block 72. The spring 73 is sleeved on the outside of the sliding post 71. One end of the spring 73 is fixedly connected to the clamping block 72, and the other end of the spring 73 is fixedly connected to the outside of the sliding post 71. The clamping block 72 clamps and limits the clamping strip 4.
[0024] In this utility model, by pulling the locking block 72 to stretch the spring 73, the locking block 72 is separated from the locking strip 4. Then, the sliding column 71 is pushed laterally to make the locking block 72 and the locking strip 4 misaligned, so that the locking strip 4 can be pushed to slide along the guide rod 3. Conversely, the locking strip 4 is limited and locked.
[0025] Please refer to Figures 3 and 4, wherein: the clamping member 10 includes a sliding frame 101, a vertical screw 102 and a movable plate 103. The sliding frame 101 is slidably installed at the bottom between the two guide rods 3. The bottom of the vertical screw 102 is slidably connected to the inside of the sliding frame 101. The top of the vertical screw 102 is rotatably connected to the movable plate 103. The outer side of the movable plate 103 is slidably connected to the inside of the sliding frame 101.
[0026] In this utility model, by pushing the sliding frame 101 to move, the movable line plate 103 is brought close to the locking strip 4. Then, the vertical screw 102 is turned to drive the movable line plate 103 to rise to be flush with the locking strip 4. Then, the sliding frame 101 is pushed to drive the movable line plate 103 to stick tightly to the locking strip 4, thereby clamping and positioning the sensitive element on it.
[0027] Please refer to Figure 4, in which: both sides of the sliding frame 101 are threaded with fastening bolts 1011, and the ends of the fastening bolts 1011 are in contact with the guide rod 3.
[0028] In this utility model, the sliding frame 101 and the guide rod 3 are locked and positioned by tightening the fastening bolt 1011, thereby achieving clamping and positioning.
[0029] Please refer to Figure 1, in which: the front pressure plate 6 is fixedly connected with the first wiring terminals 61 arranged at equal intervals, and the first wiring terminals 61 are correspondingly matched with the vertical groove 9.
[0030] In this invention, the first terminal 61 is matched with the vertical slot 9 to make contact with the pins of the sensitive unit on the card strip 4 and realize power supply detection.
[0031] Please refer to Figure 1, in which: the movable line plate 103 is fixedly connected with second terminals 1031 arranged at equal intervals, and the second terminals 1031 are correspondingly matched with the vertical slot 9.
[0032] In this invention, the second terminal 1031, in conjunction with the vertical slot 9, provides power to the pins, while the first terminal 61 provides a power supply path for detection.
[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
