Description

Technical Field

[0001] This utility model relates to the technical field of electrostatic discharge test generators, specifically a circuit cable support device for an electrostatic discharge test generator. Background Technology

[0002] Currently, when conducting electrostatic discharge tests in electrostatic discharge laboratories, the position of the loop cable changes according to the position of the discharge gun when the handheld electrostatic discharge gun is used to discharge the product under test according to the standard requirements. However, in most cases, it is difficult to ensure that the loop cable maintains a distance of not less than 0.2m from other conductive parts of the test setup. This specification requirement is often ignored.

[0003] Publication No. CN116231544A discloses a device for fixing the return wire of an electrostatic discharge test gun, including a fixing component, a connecting component, and several limiting components. The fixing component has a fan-shaped structure, and one side of its bottom is installed to the outside via the connecting component. Several limiting components are evenly installed on the outer arc section of the fixing component. The limiting components are used to limit the return wire of the electrostatic discharge gun, thereby maximizing the accuracy, reproducibility, and repeatability of the test results.

[0004] While existing technologies have achieved a certain degree of fixation for lines, their bending angle is not adjustable, making them inconvenient to use; moreover, their fan-shaped structure occupies space. Therefore, we propose a circuit cable support device for an electrostatic discharge test generator. Utility Model Content

The fixed base is mounted on the fixed bracket, and the flexible bracket is mounted on the fixed base. The flexible bracket has a hollow structure for cable passage, and the fixed base has a cable through hole.

[0007] Preferably, the flexible support includes a flexible tube, the outer side of which is covered with a protective sleeve, and an outlet connector is installed at the end of the flexible tube away from the fixed seat.
