Description

Technical Field

[0001] This utility model relates to the technical field of electrostatic tester calibration devices, specifically a calibration device for electrostatic testers. Background Technology

[0002] An electrostatic discharge (ESD) tester is a device used to measure the electrostatic voltage or charge density on the surface of an object. It is widely used in many industries such as electronics manufacturing, printing, textiles, and pharmaceuticals. It is mainly used to detect and evaluate electrostatic phenomena so that effective anti-static measures can be taken to protect sensitive electronic components from electrostatic damage and ensure the safety of the production environment and product quality. However, ESD testers may experience accuracy drift over time, so calibration devices are needed to verify and adjust the ESD tester to ensure the accuracy of its measurements.

[0003] However, the calibration device is equipped with test sockets for connecting to the test leads of the electrostatic tester. These test sockets are usually exposed. After using the calibration device, it is often simply put away without protecting the test sockets. During storage, dust and other impurities may enter the test sockets, affecting the accuracy of the calibration. Utility Model Content

[0004] The present invention aims to address the shortcomings of the prior art by providing a calibration device for an electrostatic tester. To solve the above problems, the protective components prevent dust from entering the test socket, reducing the risk of poor contact or other electrical faults caused by contamination and maintaining the optimal working condition of the device. Furthermore, the buffer components reduce the force directly acting on the calibration device when the device is accidentally dropped or impacted, thereby effectively preventing damage to internal precision components.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a calibration device for an electrostatic tester, comprising: a housing, an installation cavity inside the housing, a fixed shell inside the installation cavity, a calibration device body fixedly installed inside the fixed shell, a protective shell fixedly installed on one side of the calibration device body, a protective assembly disposed between the housing and the protective shell, the protective assembly comprising: a protective plate, a pull block, a spring b, and a locking block, and a buffer assembly disposed inside the installation cavity, the buffer assembly comprising: a damper and a spring a.

[0006] Furthermore, a movable cavity is provided on one side of the protective shell, a protective plate is provided inside the movable cavity, a limit groove is provided on one side of the inner wall of the movable cavity, and a spring cavity is provided inside the protective shell.

[0007] Furthermore, sliders are fixedly connected to the upper and lower surfaces of the protective plate, and sliding grooves are provided on both sides of the inner wall of the moving cavity. Sliding rods are fixedly connected inside the two sliding grooves, and through holes are provided on one side of each of the two sliders. Springs are sleeved on the outer sides of each of the two sliding rods.

[0008] Furthermore, a pull block is fixedly connected to one side of the protective plate, and a slot is provided on one side of the pull block.

[0009] Furthermore, a pull rod is provided at the top of the spring cavity, and a locking block is fixedly connected to the bottom end of the pull rod. The bottom end of the locking block extends into the interior of the limiting groove, and a spring b is sleeved on the outside of the spring cavity.

[0010] Furthermore, multiple dampers are fixedly installed between the outer surface of the calibration device body and the inner wall of the mounting cavity, and springs a are sleeved on the outer side of each of the multiple dampers.

[0011] Furthermore, a slot is provided on one side of the protective shell, and multiple test sockets are connected to one side of the main body of the calibration device.

[0012] The advantage of this invention is that, through the setting of the protective components, dust can be prevented from entering the test socket, reducing the risk of poor contact or other electrical failures caused by contamination and maintaining the equipment in its best working condition.

[0013] Secondly, the buffer components can absorb and disperse impact energy when the equipment is accidentally dropped or hit, reducing the force acting directly on the calibration device and thus effectively preventing damage to internal precision components. Attached Figure Description

[0023] This application provides a calibration device for an electrostatic discharge (ESD) tester. This device, through the inclusion of protective components, prevents dust from entering the test sockets, reducing the risk of poor contact or other electrical malfunctions caused by contamination and maintaining optimal equipment operation. Furthermore, through the inclusion of buffer components, it reduces the force directly acting on the calibration device in the event of an accidental drop or impact, effectively preventing damage to internal precision components. The calibration device for an ESD tester will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0024] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] Please see Figure 1-6In this embodiment, a calibration device for an electrostatic tester is provided, comprising: a housing 1, an installation cavity 101 inside the housing 1, a fixing shell 102 inside the installation cavity 101, a calibration device body 2 fixedly installed inside the fixing shell 102, and a protective shell 3 fixedly installed on one side of the calibration device body 2; a protective assembly disposed between the housing 1 and the protective shell 3, the protective assembly comprising: a protective plate 4, a pull block 401, a spring b304, and a locking block 302; and a buffer assembly disposed inside the installation cavity 101, the buffer assembly comprising: a damper 201 and a spring a202.

[0026] The protective shell 3 has a movable cavity 306 on one side, a protective plate 4 inside the movable cavity 306, a limit groove 301 on one side of the inner wall of the movable cavity 306, and a spring cavity 303 inside the protective shell 3. Slider blocks 403 are fixedly connected to the upper and lower surfaces of the protective plate 4. Slide grooves 308 are opened on both sides of the inner wall of the movable cavity 306. Slide rods 405 are fixedly connected inside the two slide grooves 308. Through holes are opened on one side of the two slider blocks 403. Springs c404 are sleeved on the outer side of the two slide rods 405.

[0027] When the test socket 203 is needed, the pull rod 305 can be pulled to cause the locking block 302 to squeeze the spring cavity 303, so that the locking block 302 is disengaged from the slot 402. At this time, the spring c404, which is in a compressed state, is released, and a force is applied to the slider 403, so that the slider 403, the protective plate 4 and the pull block 401 are reset, and the test socket 203 is exposed.

[0028] Among them, a pull block 401 is fixedly connected to one side of the protective plate 4, and a slot 402 is opened on one side of the pull block 401; a pull rod 305 is provided at the top of the spring cavity 303, and a slot 302 is fixedly connected to the bottom end of the pull rod 305, and the bottom end of the slot 302 extends into the interior of the limiting groove 301; a spring b304 is sleeved on the outside of the spring cavity 303; a through hole slightly larger than the diameter of the slide rod 405 is opened on the slider 403, and the slide rod 405 passes through the through hole on the slider 403.

[0029] When it is necessary to cover the test socket 203, the pull block 401 can be pulled, so that the protective plate 4 drives the slider 403 to slide on the slide rod 405 and compress the spring c404. The spring c404 is in a compressed state until the pull block 401 moves into the limiting groove 301 and moves along the inclined edge opened at the bottom of the locking block 302, thereby lifting the locking block 302 and squeezing the spring b304. The spring b304 undergoes elastic deformation, so that the bottom end of the locking block 302 is higher than the pull block 401, until the bottom end of the locking block 302 is aligned with the slot 402, so that the spring b304 is released, thereby pushing the locking block 302 down and locking it into the slot 402. This fixes the protective plate 4 and the pull block 401 on one side of the multiple test sockets 203, so that the protective plate 4 and the protective shell 3 can prevent external dust from entering the interior of the test sockets 203.

[0030] Multiple dampers 201 are fixedly installed between the outer surface of the calibration device body 2 and the inner wall of the mounting cavity 101. Springs a202 are sleeved on the outer side of each damper 201. A slot 307 is opened on one side of the protective shell 3, and multiple test holes 203 are connected to one side of the calibration device body 2. When the device is dropped or impacted, the springs a202 set between the mounting cavity 101 and the calibration device body 2 can absorb and disperse the impact energy, reducing the force directly acting on the calibration device. By reducing the setting of dampers 201, the vibration of the fixed shell 102 and the calibration device body 2 inside the mounting cavity 101 can be reduced, avoiding collision between the fixed shell 102 and the shell 1.

[0031] The working principle is as follows:

[0032] Since the slider 403 has a through hole slightly larger than the diameter of the slide rod 405, and the slide rod 405 passes through the through hole in the slider 403, when it is necessary to cover the test socket 203, the pull block 401 can be pulled, causing the protective plate 4 to move the slider 403 on the slide rod 405 and compress the spring c404, so that the spring c404 is in a compressed state until the pull block 401 moves into the limiting groove 301 and moves along the inclined edge opened at the bottom of the locking block 302, thereby lifting the locking block 302. The locking block 302 compresses the spring b304, causing the spring b304 to undergo elastic deformation. This causes the bottom of the locking block 302 to rise above the pull block 401 until the bottom of the locking block 302 aligns with the slot 402. This releases the spring b304, pushing the locking block 302 downward and locking it into the slot 402. This fixes the protective plate 4 and the pull block 401 to one side of the multiple test sockets 203, preventing external dust from entering the interior of the test sockets 203 through the protective plate 4 and the protective shell 3.

[0033] In use, move the calibration device of the electrostatic tester to the location where it is needed and connect the device to an external power source. Then, pull the lever 305 to cause the locking block 302 to squeeze the spring cavity 303, causing the locking block 302 to disengage from the slot 402. At this time, the compressed spring c404 is released, which will apply a lateral force to the slider 403, causing the slider 403, the protective plate 4, and the lever 401 to reset and expose the test socket 203. Then, connect the test socket 203 to the electrostatic tester through the connecting cable. Turn on the calibration device of the electrostatic tester and infer the accuracy of the electrostatic tester by reading the real-time data on the display screen on the main body 2 of the calibration device.

[0034] Furthermore, when the device is dropped or impacted, the spring a202 located between the mounting cavity 101 and the calibration device body 2 can absorb and disperse the impact energy, reducing the force acting directly on the calibration device. By reducing the setting of the damper 201, the vibration of the fixed shell 102 and the calibration device body 2 inside the mounting cavity 101 can be reduced, avoiding collision between the fixed shell 102 and the housing 1.
