Description

Technical Field

[0001] This utility model relates to the field of electromagnetic compatibility testing technology, specifically to a micro-distance electrostatic discharge testing auxiliary device. Background Technology

[0002] Currently, according to the EMC (electromagnetic compatibility) electrostatic discharge immunity test for Toyota automotive parts, the reference standard for the micro-gap electrostatic discharge test method is TSC 0504G, which requires the electrostatic discharge tip to be 0.5mm away from the pin terminal of the connector of the sample under test. However, in the test, the handheld electrostatic gun cannot accurately control this small distance, which will reduce the test efficiency and effect. Therefore, a fixing device is needed to assist the electrostatic gun to achieve micro-distance control, so as to meet the standard test requirements while improving the test efficiency and effect.

[0015] To facilitate understanding of this utility model by those skilled in the art, the specific embodiments of this utility model are clearly described below with reference to the accompanying drawings. Obviously, the specific embodiments described are merely preferred embodiments of this utility model, and not all embodiments.

[0016] like Figure 1-3 As shown, this utility model provides a micro-distance electrostatic discharge testing auxiliary device, used to assist the electrostatic gun in achieving micro-distance control during electrostatic discharge testing (micro-gap electrostatic discharge testing method, the reference test method standard is TSC 0504G). Specifically, the distance between the discharge tip of the electrostatic gun and the pin terminal of the sample being tested is 0.5mm. It includes a base plate 1, a lifting platform assembly 2, and a fixing ring 3 for fixing the electrostatic gun. The lifting platform assembly 2 includes a scale box 21, a lead screw 22, a lifting platform 23, and an adjusting handwheel 24. The scale box 21 is vertically mounted on the base plate 1, and the lead screw 22 is vertically mounted inside it. The lifting platform 23 is slidably sleeved on the scale box 21, and its sliding end is connected to the lead screw 22. The connection is such that the top of the lead screw 22 is fixedly connected to the adjusting handwheel 24 located on the top of the scale box 21, the fixing ring 3 is provided on the lifting platform 23, and the scale box 21 is provided with scale graduations on the side; the vertical height position of the electrostatic gun is adjusted to accommodate samples of different sizes. By shaking the adjusting handwheel clockwise or counterclockwise, the lifting platform will be driven by the lead screw to move up and down along the scale box, so that the height position of the electrostatic gun can be precisely adjusted. Its adjustment accuracy reaches 0.05mm, which fully meets the standard requirement of 0.5mm micro-distance control.

[0017] The lifting platform assembly 2 also includes a translation frame assembly 25 that drives the electrostatic gun to move along the X-axis direction; the translation frame assembly 25 includes a translation frame 251, a slide rod assembly 252, and a translation seat 253; the translation frame 251 is horizontally fixed on the lifting platform 23, the slide rod assembly 252 is horizontally fixed on the translation frame 251, the translation seat 253 is slidably sleeved on the slide rod assembly 252, and a fixing ring 3 is fixed on the translation seat 253; this allows the electrostatic gun to slide freely in the horizontal direction, facilitating the horizontal alignment adjustment of the discharge tip of the electrostatic gun with the pin terminal of the sample being tested.

[0018] The lifting platform assembly 2 also includes a rotating seat 26; the bottom end of the rotating seat 26 is rotatably engaged with the top surface of the base plate 1, and the scale box 21 is vertically fixed on the rotating seat 26; the lifting platform assembly realizes the rotation function through the rotating seat, which can rotate the electrostatic gun to the periphery of the base plate, thereby raising or elevating the device so that larger samples are not limited by the adjustment range of the lifting platform assembly, thus enabling testing of larger samples that exceed the effective stroke.

[0019] It also includes a calibration ruler (not shown in the attached figure) for quick calibration of the test distance. In this example, a 0.5mm ruler is preferred, which can conveniently, quickly and accurately calibrate the test distance.

[0020] The electrostatic gun also includes an extension gun head (not shown in the attached drawings); when the extension of the sample pin terminal is not applicable, the extension gun head can be used to directly contact the pin terminal, and then the distance between the electrostatic gun head and the extension gun head can be adjusted to 0.5mm. A scale hole is reserved at the rear end of the extension gun head for easy calibration of the distance using a scale.

[0021] The micro-distance electrostatic discharge testing auxiliary device provided by this utility model can adjust the position of the electrostatic gun in any vertical or horizontal direction according to the size of the sample being tested through the lifting platform assembly. It can adapt to testing samples of different sizes and makes it easier to accurately control the testing distance within 0.5mm, thereby improving testing efficiency and effectiveness and having better versatility.
