Description

Technical Field

[0001] This utility model relates to the field of electronic equipment component technology, and more specifically, to an anti-static protection device for sensitive components. Background Technology

[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 input physical quantity, such as thermistors (see thermistors), photosensors, (electro)barometers, magnetometers, 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] Existing sensors are typically soldered onto circuit boards, which makes replacement inconvenient when a fault occurs. Often, the entire circuit board needs to be replaced, resulting in unnecessary waste. Furthermore, the sensitive components are susceptible to interference and may exhibit abnormal behavior under electrostatic interference, severely affecting the normal operation of the sensor.

[0004] Patent application number CN202120413601.0 discloses an anti-static protection device for sensitive components, comprising a circuit board, an insulating shell, adjusting posts, and an anti-static rubber sheet. The top of the circuit board has four threaded holes arranged in a rectangular array, each threaded hole containing a countersunk bolt threaded through a mounting lug. The four mounting lugs are bonded to the outer periphery of the insulating shell. The bottom of the insulating shell abuts against the circuit board, and the interior of the insulating shell is integrally molded with multiple threaded posts, each threaded post being threaded to an adjusting post. An anti-static rubber sheet is bonded to the bottom of the circuit board. Circular top plates are bonded to the bottom of each of the adjusting posts, and rubber flexible sheets are bonded to the bottom of each of the top plates. This anti-static protection device for sensitive components eliminates the need for soldering, facilitating the replacement of sensitive components and the fixing of sensitive components at different heights, thus preventing the sensitive components from being affected by static electricity.

[0005] When using this structure, the adjustment mechanism needs to be adjusted before assembling the insulating shell. The degree of adjustment required varies depending on the sensitive element. If the adjustment accuracy is insufficient after adjustment, it needs to be removed and readjusted. Direct assembly may cause excessive pressure on the sensitive element and damage it.

[0007] To achieve the above objectives, the present invention adopts the following technical solution;

[0008] An anti-static protection device for sensitive elements includes an anti-static rubber sheet, a circuit board, and multiple sensitive element bodies.

The top of the insulating shell is provided with uniformly distributed limiting components, which are located on top of the sensitive element bodies.

[0009] The limiting component includes a rotating shaft rotatably connected to the top of the insulating shell.

[0023] 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;

[0024] Please see Figures 1-4 In this utility model, a sensitive element anti-static protection device includes an anti-static rubber plate 1, a circuit board 2, and multiple sensitive element bodies 3. The sensitive element bodies 3 are installed on the top of the circuit board 2, and the circuit board 2 is installed on the top of the anti-static rubber plate 1. An insulating shell 4 is detachably connected to the top of the circuit board 2. The bottom of the anti-static rubber plate 1 is equipped with uniformly distributed anti-static protection protrusions 101. Heat dissipation grooves 401 are provided on both the left and right sides of the insulating shell 4. The top of the insulating shell 4 is provided with uniformly distributed limiting components 5, which are located on the top of the sensitive element bodies 3.

[0025] The limiting component 5 includes a rotating shaft 501, which is rotatably connected to the top of the insulating shell 4. The bottom end of the rotating shaft 501 extends through and into the interior of the insulating shell 4. A threaded sleeve 502 is threadedly connected to the rotating shaft 501. The threaded sleeve 502 is slidably connected to the bottom of the insulating shell 4. A rubber flexible plate 503 is installed at the bottom end of the threaded sleeve 502. A through groove 504 is opened at the top of the rotating shaft 501. A movable column 505 is slidably connected to the inner wall of the through groove 504. The bottom end of the movable column 505 extends through and into the bottom of the rubber flexible plate 503.

[0026] The inner wall of the through groove 504 is coated with a schematic paint surface 6, which is located at the top of the movable column 505; both sides of the threaded sleeve 502 are equipped with limit sleeves 7, and the top of the limit sleeves 7 is installed on the top of the insulating shell 4; two guide grooves 10 are opened on the inner wall of the through groove 504, and the movable column 505 is slidably connected to the inner wall of the guide groove 10.

[0027] When it is necessary to install and protect sensitive components, the operator first connects the sensitive component body 3 to the circuit board 2 through the antennae, and then covers the top of the circuit board 2 with the insulating shell 4 and fixes it. At this time, the anti-static rubber plate 1 and the anti-static protective bumps 101 at the bottom can effectively eliminate external static interference.

[0028] Next, by rotating the rotating shaft 501, the threaded sleeve 502 is moved up and down along the rotating shaft 501, so that the rubber flexible plate 503 gradually approaches the sensitive element body 3. At the same time, the degree of deformation of the rubber flexible plate 503 is judged by observing the movement trend of the movable column 505 in the through groove 504. When the movable column 505 completely covers the schematic paint surface 6, it indicates that the rubber flexible plate 503 has been appropriately deformed and forms a stable limit on the sensitive element body 3. At this time, the anti-static rubber plate 1 and the anti-static protective protrusion 101 work together to effectively eliminate the influence of static electricity on the sensitive element, while the heat dissipation grooves 401 on both sides of the insulating shell 4 ensure that the heat inside the device can be dissipated in time.

[0029] In this invention, the antistatic rubber plate 1, together with the bottom antistatic protective protrusion 101, forms a double electrostatic shielding layer, effectively eliminating external electrostatic interference. At the same time, the limiting component 5 adopts a precise mechanical adjustment structure, which can change the height of the rubber flexible plate 503. The rubber flexible plate 503 provides flexible limiting protection through deformation, thereby limiting the different sensitive element bodies 3. Furthermore, the movable column 505 in the through groove 504 and the schematic paint surface 6 form a visual adjustment indication system, which can intuitively judge the limiting status and thus improve the adjustment accuracy. The overall structure is compact, and the electrostatic protection, mechanical limiting and heat dissipation functions are coordinated and unified, effectively improving the working reliability and service life of the sensitive element body 3.

[0030] Please see Figures 1-3The top of the rotating shaft 501 has two tool slots 8, and the interior of the tool slots 8 is connected to the interior of the through slot 504.

[0031] In this invention, when the user needs to rotate the rotating shaft 501, the rotation can be achieved by using a tool in conjunction with the tool slot 8, thereby improving practicality.

[0032] Please see Figure 1 and 2 The insulating shell 4 has detachable dustproof plates 9 on both the left and right sides, which shield the heat dissipation slots 401.

[0033] In this invention, the dustproof plate 9 can block dust passing through the heat dissipation groove 401, preventing dust from entering the interior of the insulating shell 4 and affecting the sensitive element body 3.

[0034] 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.
