Detailed Description
The terminology used in the description of the embodiments of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application, as will be described in detail with reference to the accompanying drawings.
Electronic devices include various electronic components, and some of the electronic components are susceptible to electrostatic interference, so that the electronic devices need to be subjected to electrostatic testing.
Static electricity test is typically performed on electronic devices using static electricity generators. The static generator may be such that the static gun may be another type of static generator. When an electrostatic generator is used to perform electrostatic testing on an electronic device, the electrostatic generator generates a series of voltages of values that are applied to the electronic device to test the withstand voltage of the electronic device. After the electrostatic generator is manufactured or used for a period of time, testing is performed to ensure that the voltage value output by the electrostatic generator is accurate.
In the related art, the electrostatic generator can be tested by means of an existing shielding room. Specifically, an electrostatic discharge target is arranged on a wall of a shielding room, an oscilloscope is placed in the shielding room, and a coaxial cable is used for connecting the electrostatic discharge target and the oscilloscope; and then the electrostatic generator is contacted with an electrostatic discharge target, the electrostatic discharge target transmits the voltage value to an oscilloscope through a coaxial cable, the voltage value is read through the oscilloscope, and the read voltage value is compared with the rated parameter, so that the electrostatic generator is calibrated.
However, other devices are usually arranged in the shielding room, electromagnetic signals emitted by the devices during operation cause interference to the oscilloscopes, so that errors of voltage values read by the oscilloscopes are larger, and when the devices do not operate, the interference to the oscilloscopes is smaller, so that errors of the voltage values read by the oscilloscopes are smaller, and therefore, the electrostatic discharge targets are arranged in the shielding room to test the electrostatic generator, and the consistency of test results in different time periods is poor. These equipment in the shielding room still need carry out the electricity through the wire and the outside various equipment of shielding room and be connected, consequently, still be provided with the opening that supplies the wire to come in and go out on the wall of shielding room, outside electromagnetic signal can get into in the shielding room through the opening, also can cause the interference to the oscilloscope.
In addition, the shielding room is usually large in size and not movable, if the electrostatic discharge target needs to be maintained or tested, the electrostatic discharge target needs to be detached from the wall of the shielding room, after the maintenance or testing of the electrostatic discharge target is completed, the electrostatic discharge target is installed on the wall of the shielding room, and the consistency of the test result is also affected by frequent disassembly and assembly of the electrostatic discharge target.
Therefore, when the electrostatic generator is tested by using the shielding room, the consistency of the test results is poor. And calibrating the static generator according to the test result, so that the consistency of the calibration result of the static generator is poor.
Based on this, the embodiment of the application provides a testing device of the electrostatic generator, and the testing device of the electrostatic generator has better consistency of testing results.

With continued reference to fig. 1 to 2, the case 110 may be made of a metal material with higher conductivity, so as to improve electromagnetic shielding of the case 110 and avoid interference of external devices to devices in the case 110. The case 110 includes four side walls 111, a top wall 112, and a bottom wall 113, and the case 110 is a rectangular parallelepiped or square surrounded by the side walls 111, the top wall 112, and the bottom wall 113.

Specifically, as shown in fig. 3, the electrostatic discharge target 120 is provided with first mounting holes 121, where the first mounting holes 121 may be threaded holes or through holes, and the first mounting holes 121 are uniformly arranged on the electrostatic discharge target 120 at intervals along the circumferential direction of the electrostatic discharge target 120.
The side wall 111 of the case 110 is provided with second mounting holes 111a, and the second mounting holes 111a may be screw holes, and the second mounting holes 111a are aligned with the first mounting holes 121 one by one.

With continued reference to fig. 2, a support 170 is further disposed in the case 110, and the oscilloscope 140 is placed on the support 170, so that the height of the oscilloscope 140 can be close to the electrostatic discharge target 120, thereby reducing the length of the coaxial cable 160, reducing the loss of the voltage signal during transmission through the coaxial cable 160, and improving the accuracy of the test result.
Referring to fig. 4, when the testing apparatus 100 using the electrostatic generator is used to test the electrostatic generator 200, the electrostatic generator 200 is mounted on the tripod 300, and the height of the tripod 300 is adjusted such that the height of the electrostatic generator 200 is consistent with the height of the electrostatic discharge target 120, the electrostatic generator 200 contacts the center of the electrostatic discharge target 120, and the electrostatic discharge target 120 is electrically connected to the oscilloscope 140, so that the voltage value of the electrostatic generator 200 is read by the oscilloscope.
Since the second mounting hole 111a is opened in the sidewall 111 of the case 110 when the electrostatic discharge target 120 is mounted on the case 110, electromagnetic shielding performance of the case 110 is affected, and in this embodiment, the problem is solved by providing the shielding member 130.

By providing the shield 130, the electromagnetic shielding property of the case 110 can be increased, and thus, interference of external electromagnetic waves to the oscilloscope 140 in the case 110 can be reduced, and thus, consistency of test results of the test apparatus 100 of the electrostatic generator can be increased.
The electrostatic discharge target 120 needs to be maintained or calibrated after being used for a period of time, the electrostatic discharge target 120 is detached from the side wall 111 of the case 110, and when the electrostatic discharge target 120 is maintained by using other test tests, the consistency of the test result of the test device 100 of the electrostatic generator is affected due to the inconsistent mounting position and fastening state of the electrostatic discharge target 120 each time the electrostatic discharge target 120 is mounted due to the repeated dismounting of the electrostatic discharge target 120.

The side of the case 110 facing the ground has a moving member 150 so that the case 110 is movable with respect to the ground. During calibration or maintenance of the electrostatic discharge target 120, the whole electrostatic discharge testing device 100 of the electrostatic generator can be moved to the vicinity of other testing equipment by the moving member 150 to perform testing, so that the electrostatic discharge target 120 in the electrostatic discharge testing device 100 of the electrostatic generator can be directly tested without detaching the electrostatic discharge target 120 from the side wall of the box body 110, and the influence of repeated disassembly and assembly of the electrostatic discharge target 120 on the consistency of the testing results of the testing device 100 of the electrostatic generator is avoided, and the consistency of the testing results of the testing device 100 of the electrostatic generator is further increased.
