Description

Technical Field

[0001] The utility model belongs to the technical field of circuit board testing, in particular to a portable circuit board clamping device. Background Art

[0002] In the prior art, the traditional tooling for testing circuit boards is mostly simple devices. The currently common integrated circuit board clamping device is mainly used to clamp the circuit board during assembly on the production line. However, the device can only clamp circuit boards of a certain shape and size, and cannot clamp circuit boards of different specifications, and cannot meet the actual testing requirements of most models and sizes of circuit boards. Although some clamping devices that can adapt to different sizes have appeared in recent years, there are hidden dangers that the circuit board cannot be firmly clamped or the circuit board is easily damaged. At the same time, the device structure is generally more complicated, and most of the parts used in the device are non-standard parts. Once the device fails, the maintenance cycle is long and difficult, which seriously affects the smooth progress of the test.

[0003] In addition, the conventional circuit board clamping device can only clamp a single circuit board and is mostly used indoors, which makes it inconvenient to carry outside for operation.

[0004] At present, there are no relevant standards and corresponding equipment for circuit board testing tools. Although various temporary tools can meet basic testing requirements, they are not suitable for batch testing and cannot meet the testing of circuit boards of various specifications and sizes. Although there have been devices that can adapt to different sizes, they are easy to damage the circuit board when clamping. Utility Model Content
