Description

Technical Field

[0001] The utility model relates to the technical field of testing, in particular to an electrostatic discharge immunity testing device for information technology equipment. Background Art

[0002] Generally speaking, when conducting ESD immunity tests on information technology equipment, different ESD events that the equipment is subjected to in the actual use environment and the impacts that may be caused by them are simulated. During the test, the equipment will be exposed to specific ESD scenarios to observe whether the equipment operates normally and whether it will be interfered with or damaged. ESD immunity tests on information technology equipment are usually performed by special test equipment. A commonly used test equipment is an ESD generator, also known as an ESD generator. ESD generators can generate ESD with different energy levels and waveforms to simulate ESD events in different situations, such as human ESD or cable ESD. The equipment is tested in these simulated environments to evaluate its ability to resist ESD. In addition to ESD generators, other auxiliary equipment may be required, such as monitoring equipment, data recording equipment, etc., to ensure the accuracy and reliability of the test process.

[0003] However, the existing generators have the following problems: the device is generally connected to the test gun through a line, and when storing, the test gun and the line are inconvenient to store; when placed on a flat surface, they are only supported by support columns, which can easily cause the device to move due to accidental contact, causing the device to fall, and also pull the line, affecting the test.

An electrostatic discharge immunity test device for information technology equipment is proposed to solve the problem.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A placing mechanism, which is arranged on the top of the generator body and is used to store the test gun and the circuit;

[0008] The fixing mechanism is arranged at the bottom of the generator body to facilitate fixing the generator body.

[0009] In a possible design, the placement mechanism includes a placement box, a top cover, two hinges, a snap ring and a connecting column. The bottom of the placement box is fixedly connected to the top of the generator body, the top cover is arranged on the top of the placement box, and the two hinges are respectively fixedly arranged on the two sides of the rear side of the top cover and the placement box by bolts. The top cover and the placement box are rotatably connected by the hinges. The front side of the top cover is fixedly connected to two No. 1 blocks, and the side of the two No. 1 blocks that are close to each other is rotatably connected to a rotating rod.

One end of the connecting column is fixedly connected to the front side of the placement box, and the snap ring is sleeved on the connecting column. The bottom of the top cover and the bottom inner wall of the placement box are fixedly provided with a cushion for reducing collision damage to the test gun and the line.

[0010] In a possible design, the fixing mechanism includes four bottom plates, four suction cups and four pulling straps. The tops of the four bottom plates are fixedly connected to the bottoms of four support columns, respectively. The bottoms of the four bottom plates are fixedly connected to the tops of four suction cups, respectively. One ends of the four pulling straps are fixedly arranged on the outsides of the four suction cups, respectively. The four pulling straps are all arranged to be in an inclined state for easy pulling.

[0011] In a possible design, a baffle for shielding and protecting the connection hole and the display screen is provided on the front side of the generator body, a threaded groove is opened on the front side of the generator body, a fixing column is threadedly connected to the baffle, one end of the fixing column passes through the front side of the baffle and is threadedly connected to the threaded groove, and the other end of the fixing column is fixedly connected to a rotating handle.

[0013] In a possible design, connection handles are fixedly connected to both sides of the generator body for facilitating holding and moving the generator body.

[0014] In this application, when in use, the generator body is moved to the place where the test is required by connecting the handle, and it is placed on the plane, and then the support column is away from the plane to reduce the influence of dust and water stains on the generator body, and the generator body is fixed by the suction cup to prevent it from moving, and the safety of the generator body is ensured, and then the clamp ring and the connecting column are separated from each other, and the top cover is opened by the hinge and the lifting plate, and the test gun and the line stored in the placement box are taken out and connected to the generator body, and the generator body uses a high voltage source or a voltage generator to transfer the charge to a large capacitor, commonly referred to as an energy storage capacitor. This large capacitor will be charged to a specific voltage level to simulate the state of static electricity accumulation, and then, when the test equipment needs to perform an electrostatic discharge immunity test, the charge in the energy storage capacitor is released. At this time, by turning on the discharge switch, the charge in the energy storage capacitor is transferred to two other smaller capacitors, which are connected to the electrodes of the device or simulate human contact and connected by the discharge switch. The charge of the capacitor is quickly released to the device to be tested through the test gun and the line, forming a simulated electrostatic discharge event, generating a high peak current, and then testing the device, and displaying the test results on the display screen on the generator body. After the test is completed, the test gun and the line are placed back in the placement box for storage to facilitate finding, and the connection holes and the display screen of the generator body are shielded and protected by baffles and fixed columns to extend the service life of the generator body, and then the suction cup is loosened by pulling the tilted setting, and the generator body is moved by the connecting handle.

[0015] The beneficial effects of the utility model are:

[0016] In the utility model, the placement mechanism and the fixing mechanism make it convenient to take out the test gun and the line used in conjunction with the generator body from the storage box, thereby facilitating the testing of the equipment, and also facilitating the finding and protection of the test gun and the line. At the same time, by providing a suction cup and a pulling belt, the generator body can be conveniently fixed on a plane to ensure the safety of the generator body, and the suction cup can also be conveniently loosened to improve the practicability of the device.
