Description

Technical Field

[0001] The present invention relates to the technical field related to electrostatic discharge test generators, in particular to loop cable supporting equipment for an electrostatic discharge test generator. Background Art

[0002] Currently, when ESD laboratories conduct ESD tests on products under test using a handheld ESD gun according to standard requirements, the position of the loop cable changes during the test depending on the position of the discharge gun. However, in most cases, it is difficult to ensure that the loop cable remains at least 0.2m away from other conductive parts of the test configuration, and this regulatory requirement is often overlooked.

[0003] Publication No. CN116231544A discloses a device for securing the return line of an electrostatic discharge gun during testing. The device comprises a fixing element, a connector, and several position-limiting elements. The fixing element is fan-shaped, with one side of its bottom portion mounted to the outside via the connector. Position-limiting elements are evenly mounted on the outer curved surface of the fixing element. These position-limiting elements are used to position the return line of the electrostatic gun, ensuring maximum accuracy, reproducibility, and repeatability of test results.

[0004] Although the existing technology has achieved the fixation of the lines to a certain extent, the bending angle cannot be adjusted, which is inconvenient to use; and the fan-shaped structure takes up space. Therefore, we propose an electrostatic discharge test generator loop cable support device. Summary of the Invention
